BACKGROUND

 General Information

   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 by
 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.

   Additional information on NMES-2 is available from Daniel C.
 Walden, Ph.D., Director of the Division of Medical Expenditure
 Studies; Center for General Health Services Intramural Research,

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 two data files and
 related documentation on the use of and expenditures for formal
 home health care and the purchase and rental of medical
 equipment, supplies and other medical items for calendar year
 1987.  The data file on home health services (File 1) contains
 information on each person in the Household Survey using these
 services in 1987.  Each record is restricted to the set of formal
 services provided during the year by each type of provider sent
 by each unique agency furnishing home health care.  Services
 provided informally by friends or family are not included.  Each
 record also contains selected person-level demographic
 information for the respective user, and household reported
 medical conditions associated with the use of home health care.

   File 2 contains one record per type of medical item per round
 for each eligible person in the Household Survey who reported
 having purchased, rented, or otherwise obtained such items during
 that round.  This file also contains selected person-level
 demographic, medical condition and date of purchase variables.

   Each data file represents all persons in the civilian
 noninstitutionalized population who used home health care, in the
 first instance, or medical equipment and supplies, in the second
 instance, for one or more reference periods during calendar year
 1987 and who responded for their entire period of eligibility.
 The files can be used to construct summary variables of
 expenditures, sources of payment and other aspects of utilization
 of home health care and purchases of medical equipment and
 supplies. NMES Public Use Tape 13 provides information on persons
 in the Household Survey without home care or without purchase of
 other medical equipment and supplies in 1987.  Also provided on
 Tape 13 are annual person-level information on other health
 services use as well as detailed demographic, employment and
 insurance information, round-specific eligibility status
 indicators and reference period dates for the entire civilian
 noninstitutionalized population.

   The data on this tape are being released as 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 records on either of the data files can be linked to all
 NMES public use tapes from the Household Survey by using the
 person identifier (PIDX).

   The following documentation offers a brief overview of the type
 and level of data provided, the content and structure of the data

 File 1:  Home Health Care Data File Structure and Contents

  General Information

   File 1 contains data pertaining to the use of and expenditures
 for home health services. To expedite release of home health data
 and ensure data processing efficiency, the file structure
 generally reflects the aggregation across rounds of the household
 questionnaire (see Attachment 3A for the instrument used). This
 file contains 1,682 records.  Each record provides variables
 related to the set of formal services provided during the year by
 a specific provider type from a unique agency furnishing home
 health care.  For example, the set of services provided by RN's
 from Home Health Agency "ABC" are represented as a single record.
 Services provided by LPN's, from Agency "ABC", a second record,
 and services by RN's from Agency "XYZ" a third record.

   File 1 variables include type of home health care provider, the
 household reported conditions related to each set of services,
 the number of visits and type of care provided, and associated
 expenses and sources of payment.  Using the number of visits
 variable (VISTNUMX) and linking all records with the same person
 identifier (PIDX) will provide the total number of home health
 care visits by all providers to each user during the survey year.

   Each record on File 1 contains the following information:

           Unique person and record identifiers

           Selected demographic variables

           Beginning and end dates of each set of home
           health care visits

           A constructed and edited variable representing the
           number of visits each health care provider made to the
           individual based on questions H32 to H46 in the home
           health booklet.

           Constructed and edited variable representing the home
           health provider type based on questions H2 and H3 in
           the home health booklet

           Variables based on questionnaire items H5 through H47
           in the home health booklet. These include the ICD-9
           codes representing the conditions for which the home
           health care provider visited, the types of services
           provided, the place of employment of the provider
           (including self-employed), average visit expenses, and
           sources of payment for each set of services as well as
           associated imputation flags.

           Weight and variance estimation variables

   Detailed information on editing of home health care provider
 type, editing of number of visits and the coding of medical
 conditions is provided in Sections 1.1, 1.2 and 1.3. The
 construction of the expense and source of payment variables and
 associated imputation procedures are described in Sections 1.4
 and 1.5. Miscellaneous edits and omissions are discussed in
 Section 1.6. Additional detail for selected variables is also
 provided in the Codebook Notes at the end of the File 2 codebook.

  Home Health Care Provider Type

   Each record on this file contains a constructed and edited
 variable (PROVTYPE) corresponding to the type of home health care
 provider whose visits were reported by the household respondent
 for 1987. Each provider is identified by profession, e.g. nurse,
 therapist.  As noted, the informal caregiving by friends or
 relatives is excluded from the file.  The variable PROVTVPE was
 logically edited using responses from questions H2 and H3 in the
 home health booklet and supplemented from matching records from
 the NMES Medical Provider Survey (information on the MPS is
 available in Section 4 and in Attachment 1B.). When the household
 data were missing, MPS data were used. When there were
 discrepancies in reporting between the two sources, they were
 resolved by examining responses, including the text variables, to
 questions about the types of services performed by the home
 health provider and by checking the specialty of the provider
 (PROVCOD). Provider type responses (PROVTYPE) were not imputed.

  Number of Visits

   The variable VISTNUMX represents all visits by a particular
 provider (or substitutes for that provider) for the whole year.
 VISTNUMX was constructed and edited from the household survey
 data in a three-step process using all the information in
 questions H32 through H46 for each round of data collection.  The
 first level of editing was to logically impute missing beginning
 dates from end dates of hospitalizations.  If no hospitalization
 occurred, missing beginning dates were imputed to the midpoint of
 the reference period in which the visits were reported to have
 begun.  A similar procedure was used for end dates.  In the
 second step, logical inconsistencies were resolved, duplication
 involving visit dates eliminated, and a visit count determined
 based upon edited beginning and end dates and the frequency of
 visits.  All editing was done at the level of a data segment.  Up
 to eight data segments were created for each record depending
 upon the branching possibilities of the questionnaire (questions
 H32 - H46).  Finally, a hotdeck imputation process was carried
 out for those in which missing data still existed. Missing values
 were imputed using a weighted sequential hotdeck procedure based
 upon known values. Variables with known values were used to form
 groups of donors and groups of recipients. Within such groups,
 data on the number of visits from donors were assigned to
 recipients, taking into account the weights associated with each
 person in the complex NMES household survey design. The
 classification variables used for this process were age, sex,
 number of conditions and provider type. An imputation flag
 indicates for each record whether the visit number for any round
 was imputed or not.

   For the purposes of this data file, the first date of the year
 indicating the beginning of home health visits from a unique
 provider type and the last date of the year indicating the ending
 of home health visits for that provider type were used to define
 the period of home health care use by that provider. The number
 of visits during that period was totaled over rounds between
 those two dates to create VISTNUMX.

  Medical Conditions

   This file contains up to four condition codes per home health
 provider record.  For each use of a home health provider (File 1)
  (or medical equipment and supplies purchase, File 2)  reported
 in the Household Survey, reasons for use in terms of related
 medical conditions were obtained from Household Survey
 respondents. This included medical diagnosis, if any, related
 history, and parts of the body affected by the condition. This
 information was used to code each condition related to the
 reported use of a provider 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 4
 provides details of the NHIS coding scheme for X-codes.

   The first condition on the record does not necessarily reflect
 the primary condition for the sample person, nor its importance
 or severity.  For 20 records, there were more than four
 conditions related to the set of home health provider visits
 comprising the record. In these cases, the conditions were
 reviewed, and the less serious conditions dropped in order to
 satisfy the four-condition limit.

   Coding 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.

  Visit Expense for Home Health Care

    The file contains the constructed and edited average visit
 expense for the home health care received by the sample person.
 The visit expense variable (VISTEXPX) reflects the average amount
 paid for a visit from all sources including out-of-pocket and
 third party payers.  Home health data were collected for all
 visits in four rounds throughout the year, but visit charges were
 only collected for the last visit in each round.  Since visit
 expenses could change between rounds of data collection, an
 overall average visit expense was calculated based on the last
 visit expense associated with each round of data collection and
 weighted by the number of visits which occurred in each round for
 which there were both visits and recorded visit expenses.

   Visit expenses on this file refer to the average visit charge
 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
 when services were delivered by providers who do not specify a
 charge for such services, such as providers who are financed out
 of budgets of governments, charities and other organizations who
 do not specify charges for their services. In these cases, a
 visit expense value was imputed from the expenses associated with
 otherwise similar services. There are no home health visits with
 zero expenses in this file.

   Data for visit expense were derived both from the home health
 questionnaire data from the Household Survey and from the NMES
 Medical Provider Survey (MPS).  MPS data were used as the primary
 data source for expense data where it was available.  The MPS was
 designed to collect data from the organization or provider
 reported by all respondents in the Household Survey who reported
 use of home health care.

   Data were edited when 1) the reported expense was a total for
 all visits rather than a per visit expense; (2) discrepencies
 were found between the MPS and Household data; (3) charges were
 exceptionally high or low; and (4) data were missing.  When a
 total figure was available rather than a visit expense, the total
 was divided by the number of visits as reported in the Household
 Survey. Outliers were checked against the length and number of
 visits and the types of services given. If no MPS expense data
 were available, the expense as reported by the household
 respondent was used. Missing values were imputed using a weighted
 sequential hotdeck procedure, based upon known values from both
 the MPS and Household data.  Type of provider, census region of
 residence and insurance coverage were used as classification
 variables and age, race, gender and marital status were used as
 sort variables.

   In total, approximately 50 percent of expense information was
 edited or imputed. All imputations were performed at the level of
 the last visit expense in each round. Each record with any
 imputed expense information contains a corresponding imputation
 flag.

  Sources of Payment for Home Health Care

   Unlike the expense variable, which refers to the average
 expense per visit, the source of payment variables refer to the
 share of total expenses paid by each source for the set of
 services represented by each record.  These percentages were
 derived from the questions about the last visit for each round.
 Each record contains 9 constructed variables which sum to 100
 percent, corresponding to the percent of the total expense (the
 sum of all visit expenses for each provider) paid by each of the
 following sources:

           Out of pocket by user or family;

           Private insurance;

           Medicaid;

           Medicare;

           Other Federal  (CHAMPUS, CHAMPVA, SSI, Indian
           Health Service facility or contact,
           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 (such as
           community health centers but 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.

   The source of payment variables reflect all home health visits
 by a specific provider type, whether self-employed or charging
 through a home health care agency. If a provider was responsible
 for 10 visits (VISTNUMX = 10), the SOP variables refer to the
 total expenses for all 10 visits (10 x VISTEXPX). Based on
 respondent reports of the percent or amount paid by each of these
 sources of payment, the source of payment variables were edited
 and, where necessary, imputed to correct for the following:  (1)
 the household-reported payer was incompatible with enrollment in
 public and private insurance programs reported for the person;
 (2) the person was not billed for the home health visit so no
 charge 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. Since the source of payment information
 is based on questions which refer to the last visit of a
 particular provider rather than all the visits of that provider,
 the cumulated data yield accurate aggregate or average estimates
 but are not necessarily accurate for any specific visit or
 individual case if the payers for the services of the provider
 changed during the year.

   As for visit expenses, the general imputation strategy for
 sources of payment used a weighted sequential hotdeck procedure.
 The classification variables used in the source of payment
 imputation included insurance coverage, type of provider, region,
 ethnicity and family income. Each record with imputed values
 contains a corresponding flag.

  Other Edits and Omissions

    Some data items from the home health care booklet were omitted
 from this file because they were components or probes used to
 construct the summary variables provided.  Omitted variables were
 considered not to be of independent analytic interest but as
 methodological probes to insure that the respondent had provided
 complete utilization and expenditure information.  The summary
 variables included on this file, such as visit expense and number
 of visits, reflect all of the components related to the home
 health information elicited in the home health care section of
 the questionnaire.

   Verification was performed on all link variables (e.g., ODUX,
 PIDX) except PROVIDX.

 File 2:  Medical Equipment and Supplies Data File Structure and Co

  General Information

   File 2 contains data on the purchase of and expenditures for
 medical equipment, supplies and other medical items.  File 2
 contains one record per type of medical item per reference period
 for each eligible person in the Household Survey who reported
 having purchased, rented, or otherwise used such medical item
 during that reference period.
    To expedite the release of the data and ensure data processing
 efficiency, the file structure generally reflects the structure
 of the household questionnaire (see Attachment 3B for the
 instrument used).  The file contains information for various
 types of medical items and related conditions, and charges and
 sources of payment, as obtained in four rounds of interviews
 covering calendar year 1987.  The persons represented on this
 file include all sampled users of medical items in calendar year
 1987 who responded for their entire period of NMES eligibility.
 The file contains 11,010 records, or one record for each type of
 medical item purchased, rented or otherwise obtained by a sample
 person during a round of data collection.  A record can represent
 one or more purchases of the particular type of item within the
 reference period.

     Each record on the data file contains the following
 information:

           Unique person and record identifiers

           Indicator of the round of data collection

           Selected demographic variables

           Type of medical item (coded in question P18 of the
           Other Medical Expenses Booklet)

           Variables based on questionnaire items P19 through P38
           of the Other Medical Expenses Booklet.  These include
           the ICD-9 codes representing the conditions for which
           the medical item(s) was used, the date when it was
           first used during the reference period, and total
           expense and sources of payment across all uses of that
           medical item(s) per record per reference period as well
           as associated imputation flags.

           Weight and variance estimation variables

   Detailed information on coding of medical items is provided in
 Section 2.1. Medical condition coding is described in Section
 2.2. The construction of the total expenses and source of payment
 variables and imputation procedures are described in Sections 2.3
 and 2.4. Other edits and omissions are discussed in Section 2.5
 and additional detail for selected variables are also provided in
 the codebook notes at the end of the File 2 codebook.

 Medical Items

    The data were collected in the Other Medical Expenses Probes
 and the Other Medical Expenses Booklets of the NMES
 questionnaire.  The medical items were identified by means of
 seven structured questions and one open-ended question which
 together comprise the Other Medical Expenses Probes.  The
 structured questions asked about the purchase, rental, or repair
 of a variety of medical equipment and supplies, including:
 eyeglasses and contact lenses, orthopedic items (crutches,
 wheelchairs, walkers, corrective shoes), hearing aid devices,
 diabetic equipment or supplies (insulin, syringes, test paper),
 prostheses, special home or car alterations or equipment (ramps,
 handrails, special bathroom fixtures, special automobile
 equipment), and ambulance services. Those medical items that
 require a prescription, such as insulin syringes, may also have
 been captured in the questions about prescription medications (no
 attempt was made to exclude medical items also reported on NMES
 Tape 14.1, Prescribed Medicine Data)  The open-ended question
 asked about the purchase of any other medical equipment.  A
 booklet was completed for each type of medical item mentioned in
 a round.  CODEITMX references the type of medical item and
 includes the original seven categories specified in the probes
 plus additional items organized to incorporate all the responses
 from the open ended question.  Thirty records referenced more
 than one type of medical item, and these additional mentions were
 coded in OMECOD2X and OMECOD3X.

    The information collected in the Other Medical Expenses
 Booklet about each item identified include:  the person who
 obtained the item(s); the medical conditions associated with the
 item(s); the date when the item(s) were bought, rented or put in
 service; the cost of the item(s); sources of payment; and the
 amount or percent of total charges paid by each source.

  Medical Conditions
           See discussion for File 1.

  Total Expense

   The file contains both the unedited (EXPTOT) and edited
 (EXPTOTX) total expenses for the type of medical item (or types
 of items in the few cases of multiple mentions) identified in the
 record as corresponding to the particular reference period for a
 given person. These variables sum all expenses paid out-of-pocket
 and by third party sources for the medical item(s) of the type
 indicated in CODEITMX, over the reference period covered by the
 record and reported in the Household Survey for the round. In the
 case of the 30 records that referenced more than one type of
 item, the edited expense refers to all items.

   Total expenses on this file 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 insurers, Medicare or Medicaid. Second, a
 dollar value was assigned to each item for which there was no
 specified total charge. For example, most equipment and supplies
 that are financed out of budgets of governments, charities and
 other organizations do not specify charges for the equipment. In
 these cases a total expense value was imputed from the expenses
 associated with otherwise similar equipment. There are no records
 on the file with zero expenses.

   Data edits addressed (1) copayment amounts reported by
 respondents as the total expense of the item(s); (2) extreme
 values; and (3) missing data.  Logical edits were performed in
 those cases where enough information existed to construct a
 logical value for total expense.  Where the reported expense
 appeared to be a copayment rather than the total cost for the
 item(s), the expense was set to missing and imputed to reflect
 the total cost rather than the copayment amount.

   A statistical procedure was used to impute a total expense
 amount from medical item records with complete information, as
 reported by the Household Survey respondent, to records with
 similar characteristics but with charge data missing.  Each
 medical item category in CODEITMX was treated as a separate group
 for imputation purposes (for a total of 47 categories).
 Covariates of total expense and charge nonresponse were
 identified through separate regression runs for the various
 medical items in CODEITMX.  These covariates were used as
 classification variables during imputation to form groups of
 donors (with known expense data) and recipient groups with
 identical characteristics but missing expense data.  The number
 of classification variables used varied according to medical item
 and included such characteristics as census region of residence,
 poverty status, gender, and whether the person had coverage from
 Medicare or private insurance, or was a member of an HMO during
 the year.  Within such groups, the median expense amount reported
 by donors was assigned to recipients.  For records missing one or
 more of the classification variables, matching was performed on
 some subset of the classification variables.  Each record with
 imputed values contains a corresponding imputation flag.  In
 total, approximately 28% of records had total expenses imputed.

  Sources of Payment

   Each record on File 2 contains 9 constructed variables which
 sum to 100 percent, corresponding to the percent of the total
 charge paid by each of the following sources:

           Out of pocket by user or family;

           Private insurance;

           Medicaid;

           Medicare;

           Other Federal (CHAMPUS, CHAMPVA, SSI, Indian
           Health Service facility or contact,
           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 (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.

   Based on respondent reports of the percent or amount paid by
 each of these sources of payment, the source of payment variables
 were edited and, where necessary, imputed to correct for the
 following:  (1)  the household reported payer was incompatible
 with enrollment in public and private insurance programs reported
 for the person; (2) the sum of the reported sources did not equal
 100 percent; or (3) 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 total expense, a statistical procedure was used to
 impute information about sources of payment.  The general
 imputation strategy for sources of payment used a weighted
 sequential hotdeck procedure.  The classification variables used
 in the source of payment imputation included insurance coverage,
 region of residence, month of purchase, and union status of the
 primary insured. Each record with imputed values contains a
 corresponding imputation flag.

  Other Edits and Omissions

    Question P18 of the Other Medical Expenses Booklet consists of
 seven prelisted categories of medical items (numbered 1 through
 7) and an Other (Specify) response category.  The responses
 recorded under Other were reviewed during editing in order to
 identify and assign a unique numeric code to the other classes of
 medical items not captured by the categories listed in the
 instrument. If the medical item was captured as an "other" and
 was the same as or similar to the prelisted categories in the
 questionnaire, it was not incorporated into the prelisted
 categories but categorized as a unique code from 11 thru 99.  The
 edited data appear in CODEITMX, where code categories 1 through 7
 reference the original data corresponding to the codes prelisted
 in the instrument, and categories 11 through 99 reference the
 codes developed to classify the verbatim responses. Because of
 this method of coding the text response, some items may be found
 in two category codes, e.g. one respondent who had wheelchair
 expenses answered the medical expenditure probe question about
 buying or renting orthopedic items such as crutches, wheelchairs,
 walkers or corrective shoes with a yes and was coded as a (2)
 orthopedic equipment, while another respondent answered the probe
 about buying or renting medical equipment besides what was talked
 about and answered an electric wheelchair which was recoded to
 (73).  A handful of records had more than one type of medical
 item listed as part of the Other response.  These additional
 mentions are coded in variables OMECOD2X and OMECOD3X.

   Unless indicated, all other Medical Expense Booklet variables
 are unedited. Skip patterns associated with unedited variables
 have not been reconciled. No editing was performed on the round
 indicator that is on this file, however, verification was
 performed on all link variables on the file.

 Variable Naming and Codebook Conventions

   A codebook is provided for each data file on this tape. The
 codebooks provide unweighted and weighted frequencies for all
 variables on each of the data files. The File 1 codebook contains
 variable information and frequency distributions for a total of
 1,682 records.  Weighted, these records represent 8,841,220 home
 health care visits to 5,878,253 persons (unweighted sample of
 1,067 persons). The File 2 codebook contains variable information
 for a total of 11,010 records. Weighted, these records represent
 all purchases of medical equipment and supplies by 50,951,843
 persons (unweighted sample of 7,322 persons).

   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 home health care booklet and round one
 medical equipment booklet are included as Attachment 3A and 3B 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

   NAME                   Variable name (maximum of 8
                          characters)

   NOTES                  Indicator of an explanatory note(s)
                          corresponding to the variable

   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.

   The following reserved code values are used:

 Sample Design and Response Rates

  NMES 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 NORC.  To
 improve the quality of the data and to allow for analysis of
 trends during 1987, it 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).

  NMES 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 survey estimates. See
 Attachment 1B for a full discussion of MPS design and response
 rates.

 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 home health care and medical
 item 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 1,067 persons who have
 positive INCALPER weights, and who used home health care and
 responded for their entire period of eligibilty are represented
 on File 1.  Only the 7,322 persons who have positive INCALPER
 weights and who purchased or otherwise obtained medical
 equipment, supplies and/or items and who responded for their
 entire period of eligibility are represented on File 2.  In order
 to produce national estimates related to the types, frequency of
 use, expenses and sources of payment for these utilizations and
 purchases, 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).  The variable on each record in File 1 containing the
 number of visits by the provider during 1987, VISTNUMX, must be
 used as an additional factor in most estimates of home health
 care utilization.

   For estimates involving persons in the Household Survey not on
 these files (e.g., in the case of File 1, persons without use of
 home health care 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, using the person-level
 identification variable PIDX.

  Basic Estimates of Utilization and Expenditures

   Basic Estimates of Home Health Care Utilization and Expenditures

   File 1 is constructed for efficient estimation of utilization
 and expenditures for home health care visits.  Such estimates
 include the total number of and expenses for visits.  The mean
 home health care visit expense, for instance, should be
 calculated as the sum of each record's weighted values for
 average visit expense multiplied by the number of visits across
 all records in the file (sum of (VISTEXPX x VISTNUMX x INCALPER))
 divided by weighted sum of the number of visits (sum of VISTNUMX
 x INCALPER).  Thus, the numerator is the national estimate for
 total expenses for home health care and the denominator is the
 population estimate for the total number of home health care
 visits.

   Subsetting to records based on characteristics of interest
 expands the scope of potential estimates.  For example, the
 number of home health care visits provided by nurses is estimated
 by summing (VISTNUMX x INCALPER) across all records with
 PROVTYPE = 1.

   The variables VISTNUMX and PROVTYPE on File 1 are used to
 replicate the home health care data provided on Public Use Tape
 13.  PROVTYPE equal to 7 identifies home health care visits by
 physicians and summing, at the person-level (PIDX), VISTNUMX from
 records with that provider type will correspond to DRHOME on Tape
 13.  Summing, at the person-level, VISTNUMX for records with
 PROVTYPE not equal to 7 will be equivalent to NONDRMHM (non-
 physician home health care visits) on Tape 13.

   Basic Estimates of Medical Item Purchase and Expenditures

   File 2 is constructed for efficient estimation of purchase or
 rental and expenditures for medical equipment, supplies or items.
 Such estimates include the incidence of and expenses for medical
 item procurement by round.  The proportion of total medical item
 expenses accounted for by the purchase of eyeglasses or contact
 lenses, for instance, should be calculated as the weighted sum of
 total medical item expense (sum of TOTEXPX x INCALPER) across all
 records in the file with CODEITMX = 1 divided by weighted sum of
 total medical item expense (sum of TOTEXPX x INCALPER) across all
 records in the file.  Thus, the numerator is the national
 estimate for total expenses for eyeglasses and contact lenses and
 the denominator is the national estimate for total expenses for
 all categories of medical equipment, supplies and items.

   This file should not be used to calculate the mean expense per
 medical item.  The variable EXPTOTX is the total expense for all
 medical items of the type identified in CODEITMX (and, where
 applicable, in OMECOD2X and OMECOD3X) acquired during the
 reference period; however, the count of items represented by this
 expense is not available (the question was not asked).  It should
 be noted that contained on NMES Tape 13 are person-level use
 variables suggesting the unique number of purchases.  In fact
 these variables (MEXP1 and MEXPOTH) are an aggregation of
 purchases for a round, where one purchase represents all
 purchases for a particular kind of item obtained during a round
 of data collection.  Consequently, mean expenditure estimates per
 item should be avoided.

   In order to replicate the Other Medical Expenses data on Public
 Use Tape 13, use the variables CODEITMX, OMECOD2X and OMECOD3X on
 File 2 of the current tape to distinguish purchase of eyeglasses
 and contact lenses from purchase or rental of other medical
 equipment, supplies or items.  A count, at the person-level
 (PIDX), of records with CODEITMX = 1 will identify acquisitions
 of eyeglasses/contact lenses (MEXP1 on Tape 13).  To reconstruct
 the Tape 13 variable MEXPOTH; i.e. procurement of medical
 equipment other than eyeglasses/contact lenses; count, at the
 person-level, records with CODEITMX greater than 1 or OMECOD2X
 greater than 0 or OMECOD3X greater than 0.

  Person-Based Ratio Estimates

   Person-Based Ratio Estimates for Persons with Use of Home Health

   When calculating ratio estimates where the denominator is
 persons, not home health visits, care should be taken to properly
 define and estimate this denominator.  If the estimate of
 interest, for example, is the mean annual home health care
 expense for users of home health care, the following strategy
 should be considered:  All expenses for a person on this file
 should be summed and a person-level total expense variable
 created (e.g., the variable X).  The mean national estimate would
 then be derived by obtaining the ratio of the weighted sum of
 total expense per person across all unique persons on the file
 (sum of INCALPER times X) divided by the weighted number of
 unique persons on the file (sum of INCALPER).  Only one INCALPER
 value for each PIDX should contribute to the calculation of the
 sums for both the denominator and numerator.

   Person-Based Ratio Estimates for Persons with Purchase
    or Rental of Medical Equipment, Supplies or Items
 
  As was the case with person-based home health care estimates,
 care should be taken to properly define and estimate the
 denominator when calculating ratio estimates where the
 denominator is persons, not medical items.  If the estimate of
 interest, for example, is the mean annual expense for hearing
 aids and/or communication devices for persons who purchased this
 type of medical equipment, the following strategy should be
 considered:  all expenses with CODEITMX = 3 or CODEITMX = 97 for
 a person on this file should be summed and a person-level total
 expense variable created (e.g., the variable Z).  The mean
 national estimate would then be derived by obtaining the ratio of
 the weighted sum of total hearing aid/communication device
 expenses per person across all unique persons on the file with Z
 greater than 0 (sum of INCALPER times Z) divided by the weighted
 number of unique persons on the file with Z greater than 0 (sum
 of INCALPER).  Only one INCALPER value for each PERSON (PIDX)
 with expenses for hearing aids and/or communication devices
 should contribute to the calculation of the sums for both the
 denominator and numerator.

   Person-Based Ratio Estimates Relative to the Entire Population

   If the ratio relates to the entire population, these files
 cannot be used to calculate the denominator, as only those
 persons with at least one home health care visit are represented
 on File 1 and, similarly, only those with at least one medical
 item purchase or acquisition are represented on File 2.  In this
 case, Public Use Tape 13 -- Rounds 1-4 Household Survey:
 Population Characteristics and Person-level Utilization, which
 has data for all sampled people, must be used to estimate
 persons.  For example, to estimate the proportion of persons 65
 and over with at least one purchase (rental or repair) of an
 orthopedic item, the current file 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 previous releases of NMES Household
 Survey public use data (see Attachment 5).  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 home health care use or expenditures (from
 File 1 on the present 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 home health care utilization 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 adjustments 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
           appearing on the present tape that are not on Tape 9.

  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.

    LASTAGE        An edited variable which identifies person 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 in NMES were edited.

    PROVCOD        Identifies the specialty of the provider on each

    PROVIDX        Unique number identifying the home health agency
                   employing the home health care provider on each
                   record (includes self-employed).  This File 1
                   variable may be used as a link to similar
                   variables on NMES Public Use Tapes 9, 14.5 and
                   14.4 (usual source of care, ambulatory medical
                   visit data and hospital stays data). The
                   identifier consists of the ODUX variable plus a
                   three digit number which was assigned to each
                   facility reported by dwelling unit respondents.
                   Since this number was assigned within a dwelling
                   unit, this identifier is not unique across
                   dwelling units. In order to link the files all
                   identification variables provided for medical
                   providers, physicians and place of care (PROVIDX,
                   DOCRIDX, PLACEIDX and IHSANIDX; the last three are
                   not provided on the current tape but are on NMES
                   Tapes 9, 14.5 and 14.4) must first be renamed to a
                   common variable name. Consistency across files for
                   provider type has not been verified, e.g., a
                   medical provider identified on the current file
                   may link to a place of care on another file rather
                   than a medical provider.

    PRVDKEY        When used in concert with the ODUX variable, this
                   File 1 variable identifies unique provider types.
                   It is an edited version of PROVIDX.  See PROVIDX.

    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.

    RECIDX         The unique record identifier on File 1.

    ROUND          Indicator of the round of data collection
                   (applies to File 2 only). Dates for each


                   sample person's rounds of data collection are
                   provided on NMES Public Use Tape 13.

    SOPTFLG        A flag indicating whether all the source of
                   payment percentages for that record were imputed
                   or provided by the household respondent. Applies
                   to Files 1 and 2.

    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
                   Section 5 of the documentation.

    TMPROVSX       This edited File 1 variable indicates the time of
                   day the set of visits occurred and incorporates
                   information from the home health questionnaire
                   (H47) on the length of stay. If the length of stay
                   was calculated to be greater than 12 hours, this
                   variable was edited to reflect the fact that the
                   visit must have occurred in both night and day.

    VISLGTHX       File 1 variable representing the average length of
                   visit by the home health provider. Constructed
                   variable which combines information from question
                   H8 and H47. Since each record reflects the
                   cumulation of data for visits over the period of
                   the survey year, the question referring to the
                   usual visit length was used to create a weighted
                   average across visits. If these data were missing
                   for any one or more rounds, information on the
                   length of stay for a particular visit (H8) was
                   used in its place. All answers were converted to
                   minutes to give a uniform unit of measure.

    VISTNUMX       File 1 variable indicating the total number of
                   visits per record by the specific home health care
                   provider for 1987. It is a constructed and edited
                   variable using questions H34, H35 and H36. See
                   Section 1.2 for details.

    VISTNFLG       File 1 flag indicating if home health visits were
                   imputed for at least one round of data collection.

    VISTEXPX       File 1 variable indicating the average visit
                   expense for each home health care provider, per
                   record.

                   This is a constructed variable based on the visit
                   charge information collected in both the Household


                   Survey and the Medical Providers Survey. See
                   Section 1.4 for details.

    VISTEFLG       File 1 flag indicating whether the source of data,
                   for the number of visits per record came from
                   either the MPS, the Household Survey or was
                   imputed.
