ABSTRACT

     This documentation describes one in a series of public use
     tapes issued by the Agency for Health Care Policy and Research
     with data from the National Medical Expenditure Survey.  This
     survey provides extensive information on health expenditures by
     or on behalf of families and individuals, the financing of these
     expenditures, and each person's use of services.  The National
     Medical Expenditure Survey (NMES) is a research project of the
     Center for General Health Services Intramural Research, Agency
     for Health Care Policy and Research.

       Since the 1970s the intramural research program has given
     particular emphasis to studies of the use and financing of health
     services.  The first series of studies (NMES-1) employed data
     collected in the 1977 National Medical Care Expenditure Survey.
     NMES-1 produced information on a broad range of issues such as
     the number and characteristics of the uninsured and the
     underinsured, the tax implications of excluding employer-paid
     premiums for health insurance from employee income, and the
     differences among socioeconomic and demographic groups with
     respect to the use of health services.

       A new series of studies (NMES-2) was initiated in the 1980s.
     These studies also involve a major data collection effort - the
     1987 National Medical Expenditure Survey.  Like its predecessor,
     NMES-2 provides information about the non-institutionalized
     population.  In addition and in contrast to the earlier studies,
     NMES-2 also provides extensive information on the population
     residing in or admitted to nursing homes and facilities for the
     mentally retarded.

       The Household Component of NMES-2 is based on a national
     probability sample of the civilian, noninstitutionalized
     population living in the community.  The sample is designed to
     provide a larger representation of population groups of special
     policy interest to the Federal Government than would have been
     obtained from a random sample.  These groups include poor and low
     income families, the elderly, the functionally impaired, and
     black and Hispanic minorities.  A Survey of American Indians and
     Alaska Natives includes a separate sample of American Indians and
     Alaska Natives living on or near Federal reservations and
     eligible to receive care provided or supported by the Indian
     Health Service.  The Institutional Population Component includes
     a sample of persons residing in or admitted to nursing and
     personal care homes and facilities for the mentally retarded
     during 1987.  A separate Medicare Records Component provides
     claims data on all Medicare beneficiaries included in the
     household and institutional samples.

       Together, the major components of NMES-2 contain information to
     make national estimates of health status, use of health services,
     insurance coverage, expenditures, and sources of payment for the
     civilian population of the United States during the period from
     January 1 to December 31, 1987.  Oversampling of population
     groups of special interest makes possible in-depth studies of
     these groups.  The database can also be used to assess the
     implications of recent or proposed changes in public or private
     health care benefits, methods of financing both health care and
     insurance coverage, various public and private subsidies for
     health care, and employee compensation arrangements.

     Household Survey

       Each family in the Household Survey was interviewed four times
     over a period of 16 months to obtain information about the
     family's health and health care during calendar year 1987.
     Baseline data on household composition, employment, and insurance
     were updated at each interview, and information was obtained on
     illnesses, use of health services, and health expenditures for
     each family member.  A fifth round of interviews was conducted in
     the spring of 1988 to obtain information on the tax filing and
     medical deductions of each household.  A long term care
     supplement was administered during the first and fourth rounds of
     interviewing to permit estimates of persons with functional
     disabilities and the use of formal services or long term care
     provided by family or friends.

       In order to verify and supplement the information provided by
     household respondents, the Household Component of NMES-2
     included two additional surveys.  The Medical Provider Survey
     obtained information from the physicians, hospitals, outpatient
     clinics, emergency rooms, and home health agencies used by the
     household sample during 1987.  The Health Insurance Plan Survey
     obtained information on the private insurance of persons in the
     household sample, including premiums paid by all sources and the
     provisions of their coverage.

     Survey of American Indians and Alaska Natives (SAIAN)

       This component was conducted with the same data collection
     instruments and interview procedures as the Household Component
     and covered the same reference period, calendar year 1987.  SAIAN
     also included follow-up surveys to medical providers and health
     insurers.  Consequently, the data can be used to compare American
     Indians and Alaska Natives eligible for care from the Indian
     Health Service and the general U.S. population with regard to
     such issues as health status, use of health services, and access
     to care.  Information was obtained on services provided outside
     the Indian Health Service and on other sources of health care
     financing available for persons eligible for care from the IHS.

     Institutional Population Component

       The Institutional Population Component of NMES-2 included
     persons resident in or admitted to nursing and personal care
     homes and facilities for the mentally retarded at any time in
     calendar year 1987.  This survey provides information on the
     functional status, use of services, and health expenditures of
     the institutionalized population.  The Survey in Institutions
     (SII) collected data from facility administrators and designated
     staff on the characteristics of facilities and charges.  The
     Survey of Next of Kin (SNK) obtained data from the respondent's
     next-of-kin or other knowledgeable persons in the community on
     the financial status, insurance coverage, and personal history of
     the institutionalized person.

     Survey Samples

       All survey components were designed to provide statistically
     unbiased estimates that are representative of the civilian
     population of the United States in 1987.  The Household Survey
     sample is a stratified multistage area probability design with a
     total sample of roughly 35,000 individuals, in 14,000 households,
     who completed all rounds of data collection.  Oversampling of the
     population subgroups of special policy interest was based on a
     separate screening interview conducted in the fall of 1986 with a
     sample of 36,000 addresses.

       The Survey of American Indians and Alaska Natives adopted a
     multistage area probability sample design using an IHS-
     constructed frame of counties with individuals eligible for
     services provided or supported by the Indian Health Service and
     living on or near Federally recognized reservations or in Alaska.
     An initial screening interview was completed in approximately
     13,700 dwelling units to identify the eligible sample.  The
     screening yielded approximately 1,950 households responding for
     the full year and approximately 6,500 SAIAN persons responded for
     their entire period of eligibility in 1987.

       The institutional population sample was based on a three stage
     probability design.  The first two stages were used to select
     facilities; the final stage sampled facility residents present on
     January 1, 1987.  These facilities were also used to obtain a
     sample of admissions between January 1, 1987, and December 31,
     1987.  Based on sampling specifications the Institutional
     Population Component includes 1,500 facilities, 800 nursing homes
     and 700 facilities for the mentally retarded.  There is a total
     of approximately 10,100 persons in the sample including both
     residents and new admissions.  This includes 5,700 persons in
     nursing homes and 4,400 persons in facilities for the mentally
     retarded.  The sample frame for facilities in the Institutional
     Population Component was derived from the 1986 Inventory of Long-
     Term Care Places.

       Taken in conjunction, the NMES-2 surveys yield comprehensive,
     population-based information that will support studies of most
     population groups of policy interest, including those presently
     outside the scope of various public and private financing
     mechanisms.  In contrast to information obtained from program or
     provider statistics, NMES-2 data can be used to analyze all
     public and private sources of coverage for health care services
     and out-of-pocket payments by individuals and families.

       The Agency for Health Care Policy and Research sponsored the
     NMES-2 data collection activities.  A substantial part of the
     support for the Survey of American Indians and Alaska Natives was
     provided by the Indian Health Service.  The Health Care Financing
     Administration, the National Center for Health Statistics, and
     the Office of the Assistant Secretary for Planning and Evaluation
     provided extensive technical assistance during the development of
     the survey design and instruments.  Interviews were conducted by
     the primary contractor, Westat, Inc., Rockville, Maryland and the
     National Opinion Research Center at the University of Chicago;
     the Council of Energy Resource Tribes, Denver, Colorado; and
     Stephen R. Braund and Associates, Anchorage Alaska.  Data
     processing during the analysis stage of the project is being
     provided by Social and Scientific Systems, Inc., Bethesda,
     Maryland.

       The data were collected under the authorities of the Public
     Health Service Act and are being edited and published in
     accordance with the confidentiality provisions of that Act and
     the Privacy Act.

TECHNICAL AND PROGRAMMING INFORMATION

 General Information

       This documentation describes one in a series of public use
     tapes from the Household Survey of the 1987 National Medical
     Expenditure Survey (NMES).  The tape provides information and
     related documentation on the use of and expenditures for
     ambulatory medical services for calendar year 1987.  This tape
     contains three data files: (1) visits and telephone calls to
     physician's offices (including HMOs and health departments) in
     settings other than a hospital or at home, and to other providers
     of care (e.g. chiropractors and psychologists), (2) visits to
     hospital outpatient departments, and (3) hospital emergency room
     visits, both regardless of provider type.  A record on any of
     these data files represents a unique ambulatory visit.  In
     addition, each record contains basic person-level demographic
     information for the respective user, dates of visits, medical
     conditions associated with the visit, and variables such as types
     of procedures performed and the main reason for the visit.

       The records on this tape represent all persons in the civilian
     noninstitutionalized population who reported ambulatory medical
     visits during calendar year 1987 and who responded for their
     entire period of eligibility.  Taken together, they represent all
     instances in which the person made an ambulatory visit to a
     medical provider during 1987.  Excluded from this tape are
     persons who were admitted and discharged from a hospital on the
     same day and had no other ambulatory care visits.  The variables
     on the tape can be used to construct summary variables of
     expenditures, sources of payment, and other aspects of the use of
     ambulatory care.

       Information on persons in the Household Survey without
     ambulatory visits in 1987 is provided on NMES Public Use Tape 13.
     Tape 13 also contains annual person-level information on other
     health services use as well as detailed demographic, employment,
     insurance, round specific eligibility status indicators and
     reference period dates for the entire civilian
     noninstitutionalized population.  The data file records on the
     current tape can be linked to all NMES public use tapes from the
     Household Survey by using the person identifier (PIDX).

       The data on this tape are being released as three EBCDIC files.
     The tape also includes an EBCDIC file containing programming
     statements required to create a SAS data set and a SAS format
     library for each data file on the tape.

       The following documentation offers a brief overview of the type
     and level of data provided, the content and structure of the data
     files and the codebooks, and programming information.  It

       More detailed information on NMES survey instruments and data
     collection procedures, variance estimation programs, and coding
     and related information are in Attachments 1 to 8, which are
     provided as hard-copy attachments to the documentation.
     Attachment 8 contains a catalogue of data items released on this
     and other NMES Household Survey public use tapes.  It is supplied
     to guide the user to the appropriate public use tape for the data
     items of interest in the NMES Household Survey.

 Structure and Contents of the Data Files

  General Information
 
      This public use tape contains three data files and represents
     the data collected by means of three separate visit booklets in
     NMES.  In addition, expenditure information from the NMES Medical
     Provider Survey (MPS) was used to supplement expenditure data
     obtained in the Household Survey.  To expedite release of data
     and ensure data processing efficiency, the structure of the files
     generally reflects the structure of the applicable household
     questionnaire (see Attachments 1, and 3 through 5 for the
     instruments used).  The files contain information on ambulatory
     services, expenses, and sources of payment as obtained in four
     rounds of interviews covering calendar year 1987.  Each record on
     these data files represents a unique visit during 1987,
     regardless of the file.  The persons represented on this tape
     include all sampled users of ambulatory services in calendar year
     1987 who responded for their entire period of NMES eligibility.
     Unless otherwise indicated, variables and variable names are
     identical across files.  The medical provider visit file (File 1)
     contains 156,957 records, the hospital outpatient visit file
     (File 2) 20,648 records, and the hospital emergency room visit
     file (File 3) 8,249 records.  An ambulatory visit is defined as a
     single contact with a medical provider for one or more services
     in either a hospital outpatient department or emergency room, or
     in a setting (such as a physician's office, a clinic, or a lab)
     other than an inpatient  hospital, a nursing home, or a person's
     home.

       Each record on the medical provider visit, hospital outpatient
     visit and hospital emergency visit files contains the following
     information:

               Unique person and record identifiers

               Indicator of the round of data collection

               Selected demographic variables

               Variables based on questionnaire items J1 through J43
               for medical provider visits (File 1), F1 thru F60  for
               hospital outpatient visits (File 2) and E1 thru E56 for
               emergency room visits (File 3) - They include the ICD-9
               codes representing the conditions for each medical
               event, dates of the visit, the total expense and
               sources of payment as well as associated imputation
               flags.  Also included on the medical provider visit
               file (File 1) and the hospital outpatient visit file
               (File 2) are questions regarding the type of health
               professional and the specialty of the medical provider
               seen during the visit, the location at which services
               were delivered, the reason for the visit, and the types
               of procedures performed.  Included on the emergency
               room visit file (File 3) only are variables
               representing whether or not the visit was a result of a
               referral, the travel time to and waiting time in the
               emergency room, and whether the emergency room visit
               resulted in an immediate hospital admission.

               Weights and variance estimation variables

       Detailed information on coding of medical conditions and
     procedures is provided in Section 1.1.  The construction of the
     expense and source of payment variables and associated imputation
     procedures are described in Sections 1.2 and 1.3.  A summary of
     the edits and omissions for the three files is provided in
     Section 1.4.  Additional details on selected File 1, 2 or 3
     variables are provided in the codebook notes which immediately
     follow the codebook for File 3.

 Condition and Procedure Coding

  Medical Condition Coding

       The three data files on this tape contain up to four condition
     codes per visit.  For each ambulatory medical visit reported in
     the Household Survey, information on reasons for use, in terms of
     related medical conditions, medical diagnosis, if any, related
     history, and parts of the body affected by the condition were
     obtained.  This information was used to code each condition
     related to the reported use into one of the codes of the 9th
     Revision of the International Classification of Diseases, revised
     for use in the National Health Interview Survey (NHIS; NCHS,
     1979).  The revision takes into account the experience of the
     National Center for Health Statistics, the sponsor of the NHIS,
     in coding household reported conditions.  One major revision of
     the ICD-9 coding procedure in surveys using the NHIS system is
     the introduction of X-codes.  These codes represent impairments
     such as blindness, deafness, and paralysis.  Coding instructions
     directed coders to favor X-codes over other ICD-9 codes that
     could be applied to a particular condition.  Attachment 6A
     provides details of the NHIS coding scheme for X-codes.

       The first condition on a record does not necessarily reflect
     the primary condition for the sample person and, more generally,
     the order of the conditions on the record does not reflect
     importance or severity.  In addition, there is a small
     probability that duplicate conditions are attached to the same
     record.  No editing to eliminate these duplications was done.

  Procedure Coding

       Each data file can contain a single procedure code per record.
     For each ambulatory visit reported in the Household Survey,
     questions were asked about operations or surgical procedures
     performed during that visit.  The respondent-reported procedure
     was used to code to one of the codes in the 9th Revision of the
     International Classification of Diseases, Clinical Modification,
     3 (ICD9-CM3) revised for use in the National Health Interview
     Survey (NHIS; NCHS, 1979).  The revision uses only the first two
     digits of the ICD9-CM3 which indicates the body system or region
     on which the procedures was performed.  For miscellaneous
     diagnostic and therapeutic procedures, the code represents a
     general procedure class, for example, "diagnostic radiology" or
     "physical or rehabilitative procedures".  Attachment 6B provides
     the codes for medical procedures.

  Quality Control

       Coding for conditions and medical procedures was conducted by
     trained medical coders.  Two-stage verification of the coding was
     performed first by supervisors and then by trained nosologists.
     Coders were required to maintain an error rate at or below 2
     percent throughout the coding process.  No additional editing or
     imputation was performed on these variables.

 Expenses and Imputation of Expenses

  General Information

         The medical provider visit file (File 1) contains only one
     expense variable, which reflects the total expenses associated
     with each visit.  The hospital outpatient department and
     emergency room visit files (Files 2 and 3) contain both facility
     and doctor expense variables for each hospital outpatient
     department or emergency room visit made by sample persons during
     1987.  These files also contain a combined expense variable which
     equals the sum of the separate facility and doctor expense
     variables for each visit (EXPTOTX).

       Total expenses on these data files refer to total charges with
     two exceptions.  First, expenses reflect payments rather than
     charges when charges were reduced to the amounts allowed by
     third-party payers such as private health insurers, Medicare, or
     Medicaid.  Second, a dollar value was assigned to each service in
     settings that do not specify a total charge for such services.
     For example, there is no stated total charge (although there may
     be copayments) for each visit to a provider in an HMO, where care
     is financed through a prepaid capitation payment rather than on a
     fee-for-service payment basis.  Also, providers who are financed
     out of budgets of governments, charities, and other organizations
     may not specify charges for their services.  In these cases where
     the expense was not otherwise accounted for, a total expense
     value was imputed from the expenses associated with similar types
     of services.  This approach was also used for most flat fee
     arrangements, when a respondent reported one lump sum charge that
     applied to a number of different medical services and there was
     no reasonable method of allocating that charge among them.

        Where the reported total expense for the visit appeared to be
     a copayment rather than the total cost for the event, the total
     expense was set to missing and imputed, as described below, to
     reflect the total cost rather than the copay amount.  The total
     expense was also set to missing and imputed for cases that
     appeared to be extreme outliers.  In cases where the respondent
     stated a visit was "free from provider", but the person was
     enrolled in an HMO or was a Medicaid recipient, the total expense
     was imputed.

       Zero total expenses occur only in situations where the charge
     for a particular service is included with other charges.  For
     example, emergency room charges were often included with
     inpatient stay charges when the emergency room visit led directly
     to an inpatient hospitalization.  As a result there are a
     relatively large number of records with zero facility expenses in
     the emergency room visit file.  There are also a large number of
     zeros in the doctor expense variables on Files 2 and 3 because
     doctor expenses are often included in the facility charges of
     hospital outpatient departments and emergency rooms.

       The edited expense variables adjust for missing or inconsistent
     values by a series of edits and imputations.  These addressed
     three major issues:  (1) potential copayment amounts which were
     mainly charges reported at the lower extreme of the total expense
     distribution; (2) potential flat fees which encompassed multiple
     visits over a course of treatment and were mainly visit charges
     at the upper extreme of the total expense distribution; and
     (3) missing charges where care was delivered under a prepaid
     arrangement such as an HMO, covered by a flat fee or by Medicaid,
     or otherwise not reported by the respondent.

       Weighted sequential hot deck imputation was used to replace
     cases with missing data.  This procedure imputes data to events
     with missing data from events with complete data, where the
     events have similar characteristics.  Cases with known values on
     characteristics of the person and other variables shown to be
     correlates of total expense and to distinguish persons with data
     from their missing data counterparts were used to form groups of
     donors for the cases with identical person and correlation
     information but with missing total expenses (called recipients).
     This procedure also takes into account the complex survey design
     and weights associated with persons with missing and nonmissing
     data. All imputations were done at the visit level with the
     exception of repeat visits (see Section 1.4).  Imputation flags
     are provided for all expense variables.

  Total Expense for File 1

       Both unedited (EXPTOT) and edited (EXPTOTX) expense variables
     are included on the medical provider visit file.  Where possible,
     expense data were obtained from linked records in the NMES
     Medical Provider Survey (MPS), which obtained provider
     information for a sample of medical events reported by household
     respondents (see Section 3.1.2 for brief description of the MPS).
     If MPS data were not available, expenses as reported by the
     household respondent were used.  If household reported data were
     not available the expense was imputed using either MPS or
     household reported data as the source data for the imputation.

       Imputations of expenses for medical provider visits (EXPTOTX)
     were performed according to type of provider (physician,
     chiropractor, podiatrist, optometrist, psychologist, others
     working for a medical doctor, and others not working for a
     medical doctor).  While the variables used to form groups of
     donors and recipients by the type of provider differed somewhat
     across imputations in the medical provider visits file, in
     general the variables used were the following: if any test was
     performed during the visit, if a third party was a source of
     payment for the visit, the patient's race and education, the
     Medicare prevailing charge index for specialists and general
     practitioners for the county in which the sampled person resided
     (obtained from the 1987 Area Resource File), region of the
     country, and type of medical condition.

  Facility Expense for Files 2 and 3

   General Information

      Both unedited (EXPFAC) and edited (EXPFACX) facility expense
     variables are included on the hospital outpatient visit and
     emergency room files (Files 2 and 3).  Facility expenses comprise
     all expenses associated with visits except those of physicians
     who bill the patient separately from the emergency room or
     outpatient department.  As with the medical provider visit file,
     where possible, facility expense data were obtained from linked
     records in the Medical Provider Survey.  If MPS data were not
     available, facility expenses as reported by the household
     respondent were used.  If household reported data were not
     available, the facility expense was imputed using only MPS data
     as the source data for the imputation.

  Facility Expenses for Outpatient Visits (File 2)

       Missing facility expenses for outpatient visits were imputed
     using a weighted sequential hot deck procedure.  The variables
     used to form the donor and recipient groups were: whether or not
     the patient had cataract surgery, whether or not the patient saw
     a physician, region of the country, use of Medicaid as a source
     of payment and performance of any diagnostic test.  The edited
     variable EXPFACX reflects this imputation on File 2.

  Facility Expenses for Emergency Room Visits (File 3)

       Missing facility expenses for emergency room visits were
     imputed with a weighted sequential hot deck using as
     classification variables: whether or not the patient had an x-
     ray, a cat scan, imaging, or surgery; type of residence of
     patient (SMSA, Non-SMSA), region of the country, age, number of
     activities of daily living for which the patient needed
     assistance, perceived health status, the cost of malpractice
     insurance for physicians in the MSA or state (outside of MSAs) of
     the sampled person, and Medicaid or Medicare as a source of
     payment.  The edited variable EXPFACX on File 3 reflects this
     imputation.

  Physician Expenses for Files 2 and 3

       Because household respondents often do not accurately report
     the physicians seen in conjunction with emergency room or
     hospital outpatient department visits, charges for physician
     services associated with visits billed separately from the
     facility charges were derived entirely from the Medical Provider
     Survey.  The variable EXPDRX (provided on both Files 2 and 3) is
     the sum of expenses for all separately billing doctors for a
     visit.

       In the Medical Provider Survey, physicians who were listed in
     the medical records for a given visit to an emergency room or
     hospital outpatient department were enumerated by specialty and
     contacted to determine the charges rendered for the visit.  When
     physician nonresponse yielded partial expenditure data for a
     visit, the missing elements were imputed using the mean MPS
     charge for a physician of that specialty.  When all physician
     charges were missing, the total was imputed using procedures
     described for the facility charge (Section 1.2.2).

  Total Expense for Files 2 and 3

       The total expense variable (EXPTOTX) on  the outpatient and
     emergency room files (Files 2 and 3) is the sum of the facility
     (EXPFACX) and the physician expenses (EXPDRX) for a visit.

 Sources of payment

     Each record on the medical provider visit file (File 1) contains
     9 constructed variables which sum to 100 percent, corresponding
     to the percent of the total expense paid by each of the following
     sources:
               Out of pocket by user or family;
               Private insurance;
               Medicaid;
               Medicare;
               Other Federal programs, which include CHAMPUS, CHAMPVA,
                Supplemental Security Income (SSI), Indian Health
                Service facility or contract, Intertribal Council,
                Alaska Native Corporation, Veteran's Administration,
                any military and other federal programs such as free
                government screening services and NIH care;
               Other State and local medical assistance programs, such
                as community health centers (excluding local and state
                employment related insurance and welfare programs);
               Workers compensation;
               Free from the provider, including professional courtesy
                and bad debt, and;
               Other, which includes automobile and car insurance,
                other kinds of insurance not specified, company (where
                the company is not the insurer), school (where the
                school is not the insurer or employer), union (where
                the union is not the insurer, or employer), charity,
                friend, foreign government or not otherwise specified.


       HMO provided visits were assigned to a source of payment
     according to the insurance status of the person who had the
     visit.  For example, if an individual had private insurance and
     the visit was covered by an HMO plan, the source of payment was
     set to private.

       The hospital outpatient department and emergency room visit
     files (Files 2 and 3) contain two separate sets of source of
     payment variables, one for the facility and a second for the
     physician expenses for each visit.

       The source of payment variables are based on respondent reports
     of the percent or amount paid by each of these sources of
     payment.  Edits or imputations were performed under the following
     circumstances: (1) the payer reported by the household was
     incompatible with enrollment in public and private insurance
     programs reported for the person; (2) the person was not billed
     for the visit so that no expenses or sources of payment were
     reported; (3) the sum of the reported sources did not equal 100
     percent; or (4) the sources of payment or the amounts or
     proportions of the payment were partially or completely missing.
     Logical edits for sources of payment were performed in those
     cases where enough information existed.  When only a partial
     source of payment was available and no logical edit was possible,
     the total distribution of sources of payment was imputed.

       As for the expense variables on all three files, the general
     imputation strategy for sources of payment used a weighted
     sequential hot deck procedure.  Source of payment imputations
     were conditional upon insurance coverage.  The classification
     variables included insurance coverage, region, date of visit,
     whether the respondent had reported a specific charge, and union
     membership of the primary insured.  In addition, visits with
     missing source of payment information and for which a Veteran's
     Administration facility was the site of care (on File 1 question
     J6=1 or question J22=4; on File 2 question F3=1 or question F16=4
     or question F36=4; on File 3 question E4=1 or question E16=4 or
     question E36=4), were assigned to the other Federal category as
     the sole source of payment.  Each record with imputed values
     contains a corresponding imputation flag.

 Other Edits and Omissions

  General Information

       Some data items from the medical provider, the hospital
     outpatient department, and the hospital emergency room
     questionnaires were omitted from these files because they were
     components or probes used to construct the summary variables
     provided.  Omitted variables were not considered to be of
     independent analytic interest but rather were methodological
     probes to insure that the respondent had provided complete
     utilization and expenditure information.  The summary variables
     included on this file, such as total expense, reflect all of the
     components collected in the medical provider visits, the hospital
     outpatient visits or the hospital emergency room visits booklets.
     Other omitted variables are box items for use by the interviewer
     in following skip patterns, interview times and names, and items
     related to the confidentiality of sample persons or respondents.
     Unless indicated, all variables on these files are unedited.
     Skip patterns associated with unedited variables have not been
     reconciled.  No editing was performed on the round indicator
     provided on these files.  Verification was performed on all link
     variables except DOCRIDX, PLACEIDX and PROVIDX.

 Repeat Visits

       Questions pertaining to repeat visits (i.e., F55-F59 in the
     outpatient visit questionnaire and J38-J42 in the medical
     provider visit questionnaire) are not represented by separate
     variables on these files.  Instead, to increase data processing
     efficiency, the data collected in these questions are represented
     as separate records, with each record representing a single
     visit.  VISITIDX is the unique record identifier for each
     outpatient department or medical provider visit.  It concatenates
     ODUX, PN, EN and RVISN.  The ODUX identifies the dwelling unit.
     The PN represents the person number.  The event number, EN,
     identifies an initial contact with a given provider for specific
     services during a round.  RVISN is the numerical identifier for
     any repeat visit within one data collection round to the same
     provider for the same services at the same expense.  The value
     for RVISN for the first visit equals zero and all repeat visits
     associated with that visit are numbered consecutively (RVISN = 1
     to n).  The first visit and all of the repeat visits share the
     same event number (EN).  All characteristics of the initial visit
     (except the date) are assigned to the repeat visits.

 Type of Provider

       A variable ascertaining the type of provider seen during a
     medical provider visit (MVISCLAS) is included on File 1.  It was
     constructed based on both information reported on the doctor
     roster developed during the survey year and from selected
     questions in the medical provider visits booklet.  This variable
     is not in all cases consistent with the specialty information
     provided in questions J10 and J12.

  Persons with Zero Night Stays

       In a number of cases, hospital outpatient department visits may
     have been reported by the household respondent as a hospital
     admission, but with admission and discharge dates on the same
     calendar day.  Since these events were reported as hospital
     admissions they, and related expenditures and sources of
     payments, are included on the hospital stays file (NMES Public
     Use Tape 14.4, Household Survey, Hospital Stays, Calendar Year
     1987).  In order to provide a more complete picture of persons
     with ambulatory hospital use, persons with both outpatient
     department use and zero night hospital stays can be identified
     with the person-level variable ZERONITE provided on File 2.
     Persons with only zero night stays are not included on the
     outpatient department file (File 2), see Section 4.1.

 Variable Naming and Codebook Conventions

       Three codebooks are provided, one for each file.  The codebooks
     provide unweighted and weighted frequencies for all variables on
     the files.  These codebooks contain variable information and
     frequency distributions for the following:

               A total of 156,957 records for the medical provider
               visits file,

               A total of 20,648 records for the outpatient department
               visit file,

               A total of 8,249 records for the emergency room visits
               file.

     Weighted, these records represent:

               1,112,032,040 visits to a medical provider by
               171,936,150 people (156,957 unweighted visits by 24,336
               people);

               131,906,328 visits to a hospital outpatient department
               by 41,521,102 people (20,648 unweighted visits by 6,216
               people)

               53,424,204 visits to a hospital emergency room by
               37,702,370 people (8,249 unweighted visits by 5,728
               people).

       Complete variable listings in alphabetical order and by file
     position are provided for cross-reference for each file.  Most
     variable descriptors in the codebooks are abbreviated versions of
     questionnaire items, preceded by indicators of item number.  A
     copy of the round one medical provider visit, hospital outpatient
     department visit and hospital emergency room visit booklets are
     included as Attachments 3 through 5 to this public use tape to
     permit a full understanding of the content and wording of each
     item, the structure of questionnaire sections, skip patterns and
     administrative information.

       Each codebook describes an EBCDIC data set and provides the
     following programming identifiers for each variable:

       IDENTIFIER                       DESCRIPTION
       ----------                       -----------

       END                    Ending column position of variable in
                              the record

       NOTES                  An asterisk indicating an explanatory
                              note(s) corresponding to the variable.
                              Explanatory notes can be found in the
                              Codebook Note Section

       In general, variable names reflect the content of the variable,
     with an 8 character limitation.  For edited versions of original
     variables, the edited variable name is identical to the original
     variable with an "X" appended (and truncated when necessary to
     comply with the 8 character limitation).  For variables
     corresponding to specific questionnaire items, the question
     number is included in the variable label.  Variables common to
     more than one file (e.g. conditions associated with the visit)
     are identically named for ease of data processing.

       The following reserved code values are used:

       VALUE                            DEFINITION
       -----                            ----------

 Sample Design and Response Rates

  Household Survey

       The NMES Household Survey was designed to produce national
     estimates representative of the civilian noninstitutionalized
     population of the United States as of 1987.  For sample
     selection, the household component of NMES used two independent
     national multistage area samples from Westat, Inc. and the
     National Opinion Research Center at the University of Chicago.
     To improve the quality of the data and to allow for analysis of
     trends during 1987, the Household Survey was conducted as a panel
     survey over four core rounds of interviewing.

       Sampling specifications required the selection of about 17,500
     households for the first core household interview.  Data were
     obtained for about 86 percent of eligible households in the first
     interview and 80 percent by the fourth interview.  Approximately
     6 percent of all survey participants provided data for only some
     of the time in which they were eligible to respond.  These
     persons were considered total nonrespondents and a standard
     nonresponse weight adjustment was used to account for possible
     selection bias in this respect.  For a detailed description of
     the survey design and of sampling, estimation, and adjustment
     methods see Cohen, DiGaetano, and Waksberg (1991).

  Medical Provider Survey

       The Medical Provider Survey (MPS) in NMES was primarily
     designed to reduce the bias associated with national medical
     expenditure estimates derived from household reported data.  This
     bias is a function of item nonresponse and poor quality data.  By
     selectively targeting (1) individuals who were most likely to
     misreport or not possess adequate knowledge about their medical
     expenditures and (2) medical care events that were expected to be
     associated with charge data of questionable quality, optimal use
     could be made of medical provider reported data to improve the
     accuracy of national medical expenditure estimates (See
     Attachment 1B for a full discussion of MPS design and
     objectives).

 Estimation and Sampling Weights
 
  General Information

       The application of appropriate sampling weights is essential to
     the derivation of estimates when using these public use files.
     The weight provided for use with ambulatory care data, INCALPER,
     reflects adjustments for complete nonresponse to the NMES survey
     and poststratification to the Census Bureau 1987 Current
     Population Survey (CPS) cross-classified by age, race/ethnicity,
     gender and poverty status.  All persons who were eligible at any
     time during 1987 and responded for the entire period of their
     eligibility have positive INCALPER weights.  Only the 24,336
     persons who have positive INCALPER weights and who received
     ambulatory care at a medical provider's office are represented on
     the medical provider visit file.  Similarly, only the 6,552
     persons who have positive INCALPER weights and who received care
     at an outpatient department are represented on the hospital
     outpatient department file.  And finally, only the 5,728 persons
     who have positive INCALPER weights and who received ambulatory
     care at an emergency room are represented on the hospital
     emergency room file.

       In order to produce national estimates related to the site, the
     frequency of use, and expense and sources of payment for
     ambulatory care, the value in each record contributing to the
     estimates must be multiplied by the weight (INCALPER) contained
     on that record.  It should be noted that the weight, INCALPER,
     can also serve as a person-level estimation weight (see NMES
     Public Use Tape 13).

       For estimates involving persons in the Household Survey not on
     these files (e.g., persons without use of any ambulatory care
     services in 1987) or for detailed person-level characteristics of
     users, including round specific eligibility status and reference
     period dates, the data on these files should be merged with NMES
     Public Use Tape 13. (see Section 4.3) using the person-level
     identification variable PIDX.

  Basic Estimates of Utilization and Expenditures

       These files are constructed for efficient estimation of
     utilization and expenditures for ambulatory care.  Such estimates
     include the total number of and expenses for ambulatory care
     visits.  The mean expense for emergency room visits, for
     instance, should be calculated as the weighted sum of the total
     expense across all records in File 3, the Hospital Emergency Room
     visit file (sum of EXPTOTX x INCALPER on File 3) divided by the
     weighted sum of the number of emergency room visits (sum of
     INCALPER on File 3).  Thus, the numerator is the national
     estimate for total expenses for emergency room care, and the
     denominator is the population estimate for the total number of
     emergency room visits.

       Subsetting to records based on characteristics of interest
     expands the scope of potential estimates.  For example, the
     number of medical provider visits paid for, totally or in part,
     by private insurance is estimated by summing INCALPER on File 1
     across all records in File 1 for which the private insurance
     source of payment variable (SOPTPRVT) is greater than zero.

        To analyze data from these 3 files for ambulatory care across
     sites, any two or all three files may be concatenated to create a
     single data set containing all of the observations from the input
     data files.  However, the contents of these files are not totally
     identical.  Where feasible and appropriate, variables have been
     named consistently across files.

       The variables MVISCLAS and SEETLKMX on File 1, the Medical
     Provider Office visit file, can be used to replicate the
     physician utilization data provided on NMES Public Use Tape 13.
     MVISCLAS equal to 2 identifies office visits to physicians
     (DRVISITS on Tape 13), while MVISCLAS greater than 2 indicates an
     office visit to a nonphysician (NONDRVIS on Tape 13).  For
     records with MVISCLAS equal to 1, which indicates that the
     service was provided by phone, use the variable SEETLKMX (on file
     1 of the current tape)  to distinguish calls taken by physicians
     (DRTEL on Tape 13) from those taken by nonphysicians (NONDRTEL on
     Tape 13).

       In order to replicate all the hospital outpatient department
     utilization data provided on NMES Tape 13, zero night hospital
     stays (NUMNGHTX = 0) from Public Use Tape 14.4 - HHS Hospital
     Stay data should be included with the outpatient department
     visits on File 2 of the current tape to produce estimates.  To
     reconstruct the Tape 13 variable DROPD (i.e. outpatient visits to
     physicians), combine the zero night hospital stays from Public
     Use Tape 14.4 with the outpatient department records which have
     SEEDOCX equal to 1 from File 2 of the current tape.  SEEDOCX not
     equal to 1 on File 2 on the current tape identifies outpatient
     visits to medical providers other than physicians (NONDROPD on
     Tape 13).

       Emergency room visit data is defined identically on File 3 of
     the current tape and on Public Use Tape 13.  To identify records
     for emergency room visits which resulted in hospitalization
     (EROMHO on Tape 13) select records on File 3 for which the
     variable ADMTHOSX equals 1.

  Person-Based Ratio Estimates

   Person-Based Ratio Estimates for Persons with Use of Ambulatory

       When calculating ratio estimates where the denominator is
     persons, not ambulatory medical visits, care should be taken to
     properly define and estimate this denominator.  If the estimate
     of interest, for example, is the mean charge for all the visits
     to outpatient departments across all users of outpatient
     services, not including zero night hospital stays, the following
     strategy should be considered.  All expenses for a person on the
     hospital outpatient department visit file (File 2) should be
     summed and a person-level total charge variable created (e.g.,
     the variable X).  The mean national estimate for outpatient
     department visit expense would then be derived by obtaining the
     ratio of the weighted sum of total expense per person across all
     unique persons (each unique value of PIDX) on the file (sum of
     INCALPER times X on File 2) divided by the weighted number of
     unique persons on the file (sum of INCALPER) on File 2.  Only one
     INCALPER value for each PIDX (i.e. each person) should contribute
     to the calculation of the sum for this denominator and numerator.

   Person-Based Ratio Estimates Relative to the Entire Population

       If the ratio relates to the entire population, this tape cannot
     be used to calculate the denominator, as only those persons with
     at least one ambulatory visit to a provider's office, to an
     emergency room or to an outpatient department are represented on
     this tape.  In this case, Public Use Tape 13 -- Rounds 1-4
     Household Survey: Population Characteristics and Person-level
     Utilization, which has data for all sample people, must be used
     to estimate persons.  For example, to estimate the proportion of
     children 5 to 12 years of age with at least one office visit for
     streptococcal sore throat, File 1 of the current tape is used to
     calculate the numerator and NMES Tape 13 is used to calculate the
     denominator.

  Sampling Weights for Merging Previous Releases of NMES
 
   Household Data with the Current Tape

       There have been several previously released public use data
     tapes (see Attachment 7).  Unless a variable name common to
     several tapes is provided, the sampling weights contained on
     these tapes are tape-specific.  The tape-specific sampling
     weights reflect minor adjustments to eligibility and response
     indicators due, among other factors, to birth, death, or
     institutionalization among respondents.  Adjustments to the
     weights have also included post-stratification adjustments to
     control for the distribution of the U.S. noninstitutionalized
     population by poverty status and, where appropriate, nonresponse
     adjustments for round-specific supplemental questionnaires (e.g.,
     the health status questionnaires).

       For estimates from a NMES data file that do not require merging
     with variables on other NMES files, the sampling weights provided
     on that tape are the appropriate weights.  When merging a NMES
     household survey tape to another NMES household survey tape, the
     major analytical variable (i.e., the dependent variable)
     determines the correct sampling weight to use.  For example, for
     1987 estimates of emergency room use or expenditures (from File 3
     of the current tape) using health status variables from NMES
     Public Use Tape 9, the full-year weight, INCALPER, on the present
     tape should be used.  By contrast, the weight HSQACCWT from
     Public Use Tape 9 should be used when the major dependent
     variable is health status and emergency room visits is an
     independent variable.  Three exceptions to this general sampling
     weight and merge rule are noted below.  For details concerning
     the appropriate weight specific to each tape, see the hard copy
     information specific to each tape.

               (1) For estimates of round one data from NMES
               Public Use Tape 3 (preliminary round one person
               characteristics and functional health status data), the
               round one weight (WGTR1PER) provided on NMES Public Use
               Tape 13 should be used.  It should be noted that as a
               result of further response and eligibility edits, not
               all persons with positive round one weights on Tape 3
               will link when merging it to Tape 13.  In those
               instances, an imputation or weighting strategy can be
               developed to adjust for all persons with positive
               WGTR1PER weights.  The preferred approach is to use the
               round one data and the round one weight released on
               NMES Tape 13.

               (2) For point in time estimates of persons with
               activity of daily living and instrumental activity of
               daily living difficulties (Tape 10), the round one or
               four weight (WGTR1PER and WGTR4PER, respectively),
               provided on NMES Tape 13 should be used in all
               instances of merged data regardless of the type of
               analysis.

               (3) NMES Public Use Tape 4, which contains prescribed
               medicine data for the Medicare beneficiary population,
               should not be merged with the current tape (or any
               other NMES public use file) because of adjustment to
               the sampling weights made after the release of Tape 4.

       It should be noted that the sampling weight provided on NMES
     Tape 9 (HSQACCWT) reflects nonresponse adjustments specific to
     the health status questionnaire and access to care supplement
     data on that tape.  This further nonresponse adjustment requires
     additional considerations in merging Tape 9 with the current
     tape.

               (1) When making estimates for data in the current tape,
               the sampling weights provided on the current tape
               should be used.  Since this would include persons not
               on Tape 9 in the analysis, data items from Tape 9 will
               have missing values for these persons.

               (2) When making estimates of health status or access to
               care indicators, the Tape 9 weight, HSQACCWT, should be
               used.  This weight adjusts for the exclusion of persons
               included on the present tape.

  Variance Estimation

       Variance estimates of sample statistics require that the
     complex nature of the NMES Household Survey design be taken into
     account for hypothesis testing and for the construction of
     confidence intervals.  To obtain variance estimates of statistics
     by means of statistical programs that use the Taylor series
     method of variance estimation, variables must be used that denote
     the strata and the primary sampling unit (PSU) within a given
     stratum.  The variables STRATUMX and SPSU are these variables,
     respectively and are included on the data file.

       There are variance estimation programs that account for the
     complex survey design.  A list of available variance estimation
     programs is produced in Attachment 2.

FILE 1 MEDICAL PROVIDER VISIT CODEBOOK

 General Information

 THIS CODEBOOK PROVIDES UNWEIGHTED AND WEIGHTED FREQUENCIES FOR THE
 USE OF MEDICAL PROVIDERS IN AMBULATORY OFFICE SETTINGS FOR CALENDAR
 YEAR 1987. THE DATA FILE CONTAINS ONE RECORD PER MEDICAL PROVIDER
 VISIT FOR EACH PERSON IN THE HOUSEHOLD SURVEY WHO REPORTED HAVING
 SEEN OR TALKED TO A MEDICAL PROVIDER (INCLUDING PHYSICIANS OF ALL
 SPECIALITIES, MEDICAL PROVIDERS WORKING UNDER THE SUPERVISION OF A
 PHYSICIAN, AND NONPHYSICIAN PROVIDERS SUCH AS PSYCHOLOGISTS,
 CHIROPRACTORS, AND PODIATRISTS) DURING THE REFERENCE PERIOD.  BASIC
 DEMOGRAPHIC INFORMATION FOR EACH PATIENT, MAIN REASON FOR THE VISIT
 AND ADDITIONAL CONDITIONS AS REPORTED IN THE HOUSEHOLD SURVEY, AND

 WEIGHT DESCRIBED AT THE END OF THIS CODEBOOK MUST BE USED.
 INFORMATION CONCERNING SAMPLE DESIGN AND VARIANCE ESTIMATION IS
 PROVIDED IN THE FILE DOCUMENTATION.  FOR VARIABLES CORRESPONDING
 DIRECTLY TO QUESTIONNAIRE ITEMS, THE ITEM NUMBER IS PROVIDED IN
 THE VARIABLE DESCRIPTOR, WHICH ALSO IDENTIFIES EDITED VARIABLES.
 FOR VARIABLES WITH AN ASTERISK IN THE RIGHTMOST COLUMN,
 EXPLANATORY NOTES ARE PROVIDED AT THE END OF THE CODEBOOK IN
 ALPHABETICAL ORDER OF THE VARIABLE NAME.

                    on File 1, the reported specialty was edited to
                    resolve inconsistencies with response to
                    question(s) J5 (WHRSEEMP), J13 (PRSNPROV), J15/J17
                    (ICD1-ICD4), and J18 (XRAY-DIAGTEST).  No other
                    editing was performed.

     DOCRIDX        Provider identification variables constructed to
     PLACEIDX       link medical providers, physicians, and places of
     PROVIDX        care (PROVIDX, DOCRIDX, PLACEIDX) across NMES
                    household files.  Responses to questions
                    identifying the medical provider seen or talked to
                    (File 1; question J10), or the supervising
                    physician (File 1; question J12), or the provider
                    who met the sampled person in the emergency room
                    (File 3; question E8) and the hospital visited
                    (File 2; question F4, and File 3; question E5)
                    were converted to numerical identifiers.  These
                    variables link to the corresponding variables on
                    Files 1, 2 and 3 and to NMES Public Use Tape 14.2
                    (question H6, home health visit file); Public Use
                    Tape 14.4 (question G2; hospital stay file), and
                    Public Use Tape 9 (questions W5, W12 or W15; usual
                    source of care file).  Each identifier consists of
                    the ODUX variable plus a three-digit number
                    assigned to each provider, physician, or place of
                    care reported by a dwelling unit.  Since this
                    number was assigned within a dwelling unit, this
                    identifier is not unique across dwelling units.
                    Also, if the respondent saw a provider in more
                    than one location it is possible to have a
                    different provider ID for each location.  For
                    linkage, these variables (DOCRIDX, PROVIDX,
                    PLACEIDX, and IHSANIDX; the latter on Tape 9 only)
                    must be renamed to a common variable name.
                    Provider type has not been verified across files.


     EN             These variables (Files 1 and 2)
     EVENTIDX       identify and link multiple or repeat ambulatory
     RVISN          visits.  VISITIDX is the unique record
     VISITIDX       identifier for each ambulatory visit.  The
                    event number, EN, identifies an initial
                    contact with a given provider for specific
                    services during a round.  RVISN is the numerical
                    identifier for repeat visits within one data
                    collection round to the same provider for the same
                    services at the same expense.  Here, RVISN
                    for the first visit equals zero and all repeat
                    visits associated with that visit are numbered
                    consecutively (RVISN=1 to n).  The first visit
                    and all repeat visits share the same event number.
                    There are no repeat visits on the Emergency Room
                    visit file (File 3) and the unique record
                    identifier is EVENTIDX.  EN as provided on the
                    Emergency Room file identifies each ER visit for a
                    person.

     EXPDRFLG       A flag indicating whether the facility expense
     EXPFCFLG       (EXPFCFLG on Files 2 and 3), physician expense
     EXPTFLG        (EXPDRFLG on Files 2 and 3), or total expense
                    (EXPTFLG on File 1) was imputed, provided directly
                    from the household respondent or taken from the
                    Medical Provider Survey.

     EXPDRX         On the medical provider visit file (File 1) the
     EXPFAC         unedited charge (EXPTOT) and edited expenditure
     EXPFACX        (EXPTOTX) variables reflect total expense
     EXPTOT         for each 1987 medical provider visit.  On the
     EXPTOTX        hospital outpatient file (File 2) and the
                    emergency room file (File 3), the unedited charge
                    (EXPFAC) and edited (EXPFACX) facility expense
                    represent the total charges for outpatient
                    facility care excluding separately billed charges
                    for physician services, which are represented by
                    the constructed variable EXPDRX.  For editing and
                    imputation procedures, see Section C.1.2 of the
                    documentation.

     ICD1           Variables indicating up to 4 different medical
     ICD2           conditions associated with the visits on Files
     ICD3           1-3.  They represent both conditions
     ICD4           reported by the household respondent as the reason
                    for the visit (File 1, J15; File 2, F9; File 3,
                    E11) and conditions as discovered during the visit
                    reported by the household respondent. (File 1,
                    J17; File 2, F11).  The variables do not
                    distinguish between reason for visit and
                    physician-discovered conditions.

     INCALPER       Weight adjusted for nonresponse and post-
                    stratified to U.S. census data.  Estimates of
                    utilization and expenditure for ambulatory medical
                    events require the use of weighted data.  For
                    details on this weight, see Section 4 of
                    documentation.

     LASTAGE        An edited variable which identifies the person's
                    age, in years, as of the end of the last round in
                    1987 for which the person was eligible.  Less than
                    0.1 percent of the cases were edited.

     MVISCLAS       Constructed variable (File 1) that indicates
                    the provider type for medical provider visits.

     PLACEIDX       See DOCRIDX.

     PREGFLG        A constructed variable which indicates whether the
                    visit was associated with a pregnancy.  Pregnancy
                    related visits were identified using the
                    following: (i) any condition code in the
                    ranges 6300-6769, V220-V222, V230-V239, V240-V242
                    and V300-392; (ii) a procedure code in the range
                    72-75; (iii) a pregnancy related reason given for
                    the visit on File 1 (PRSNPROV = 4) or File 2
                    (WHYVIST = 4); (iv) a flat fee which also
                    covers events having any of the characteristics of
                    items i, ii, or iii.

     RACE3          A person-level variable constructed to facilitate
                    the poststratification of the NMES person-level
                    sampling weights by race and ethnicity,
                    considering three mutually exclusive
                    classifications:  Hispanic, Black--non-Hispanic,
                    and white or other.

     RACE6          An edited variable indicating race.  Less than 0.2
                    percent of cases were edited.

     SOPDFLG        Variables indicating whether all the sources of
     SOPFFLG        payment were provided by the household respondent
     SOPTFLG        or imputed.  SOPTFLG relates to sources of payment
                    for a record on File 1; SOPFFLG and SOPDFLG are
                    common to the outpatient visit file (File 2) and
                    the emergency room visit file (File 3).

     SPSU           To obtain variance estimates of sample statistics
     STRATUMX       by means of standard statistical programs that use
                    the Taylor series linearization method of variance
                    estimation, variables must be used that denote the
                    strata and primary sampling unit (PSU) within a
                    given strata.  The variables STRATUMX and SPSU are
                    these variables, respectively.  For details on
                    sampling weights and variance estimation, see the
                    Technical and Programming section on this file and

     WHRSEEMP       Variable indicating place of care.  The skip
                    patterns associated with these questions
                    (J5 and Box J2; File 1) have not been edited.  As
                    a result, File 1 includes 11 home health provider
                    visit records and 303 hospital outpatient,
                    hospital inpatient, or emergency room visit
                    records.  Categories 12-24 were created for this
                    variable after reviewing "other specify" text
                    fields for question J5.  Possible positive values
                    for this variable are:
