Health Insurance Supplement, 1996
DSN: CC37.NHIS96.HEALTHIN1996 National Health Interview Survey (NHIS) Health Insurance Public Use Data File 1. The 1996 National Health Interview Survey (NHIS) Health Insurance data file contains a variety of data items addressing health insurance. These data items are essentially the same as in other recent years with a few exceptions. The differences are: A) All Medicare recipients were asked about "Medicare Managed Care plans." B) All Medicaid recipients were asked about "Medicaid Managed Care plans." C) For those with private general purpose health care plans, coverage of dental care was ascertained instead of coverage for mammograms. The coding scheme for the private insurance plans has changed completely from previous years. The new codes are more directly related to newer types of managed care. As a result, many of the recodes relating to earlier HMO coverage have been deleted. These fields have been left blank on the file so that the fields that are consistent between 1996 and previous years are retained in the same locations. As a result of the Federal government furlough, two weeks of data collection were omitted in January of 1996. In addition, in orde to test the changing NHIS core questionnaire, for much of the year the sample was split between the old (paper) and new (computerized) versions of the core questionnaire. This data file includes only data obtained from the paper version of the NHIS questionnaire. As a result, the sample size is considerably smaller than in the previous year (63,402 vs. 102,467). The weights have been adjusted for these factors to produce national estimates. 2. The 1996 Health Insurance supplement was administered for the full year (except as mentioned above) in all of the NHIS sample households which were interviewed using the paper core NHIS. Information was collected from a household respondent about all family members who participated in the NHIS. The 1996 Health Insurance file is structured in the following way: a. The NHIS person record from the core questionnaire (locations 1-189) b. The weight fields (locations 190-335) c. Fields needed for calculating variances (locations 342-358) d. Data from supplement (locations 401-554) Note: All data from the Health Insurance supplement have been shifted to start in location 401 in order to accommodate a longer public use person record required by the new sample design in 1995. As noted above, fields that are the same as in 1995 are in the same locations, but many old recode fields pertaining to private health insurance have been left blank as a result of the change in the plan coding. 3. In 1996, two types of item non-response were identified: (1) "Not ascertained" (codes 8, 98, or 998) includes blanks when there should have been a response or when an impossible code appeared and; (2) Responses of "don't know" or "refused" when the question was asked (codes 9, 99 and 999). 4. The overall response rate for the 1996 Health Insurance was 89.8 percent. This response rate was calculated as follows: Household response rate from core of 93.8 percent multiplied by the 95.7 percent who responded to the Health insurance section yields an overall response rate of 89.8 percent. Dummy records were created for those with no response to the entire section (see file location 401). 5. Weights and variances: Since the NHIS uses a multistage sample design to represent the civilian non-institutionalized population of the United States, weights must be used to make accurate estimates based on data from the National Health Interview Survey. A set of weights are included on the 1996 file: The first weight listed below (i.e. the Final Basic Weight) will be used in most analyses of the Health Insurance data. The Final Basic Weight (location 219-227) is the equivalent of the Annual Final Basic Weight found on the NHIS Person Record of the Basic Health and Demographic component of the survey (i.e. the Core questionnaire). A national estimate of all person level variables can be made using this weight. This weight will be used in conjunction with Health Insurance data items in file locations 401-554. The Final Quarter Basic Weight before age-sex-race/ethnicity adjustment (loc. 172-177) is required by some software packages for variance estimation for surveys with complex sample designs. This weight is also included on the file. As mentioned above, the sample design for the NHIS was changed for 1995. Data from 1995 and 1996 can be combined with data from previous years, however, variances for 1995 and 1996 must be calculated separately from variances of previous years. In addition, because of the smaller sample size in 1996, some of the design elements were combined for reasons of confidentiality. The exact changes are included in explanation below. There are a number of computer programs that yield variance estimates for data based on complex sample surveys. Some are based on replication approaches and others are based on Taylor linearization approaches. In addition to the Final Quarter Basic Weight before age-sex-race/ethnicity adjustment (which is the weight prior to post-stratification), included on the Health Insurance file is the collapsed variance stratum (loc. 354- 357), the variance PSU (loc.358), the substratum for variance estimation (loc. 342-343), the secondary sampling unit (344-350), Panel 4 (loc. 352), and the NSR status variable (loc. 353) to permit the analyst the capability of using such variance estimation procedures. These variables and weights are necessary for directly calculating sampling variances. 6. Estimating annual numbers of events or conditions a. To reduce respondent error, the recall period for questions about some events is limited to two weeks. These events are: bed days and other restricted activity days, work loss and school loss days, and doctor visits. The two-week variables are found in locations 98-107 and 120-121. Estimates of the total number of occurrences of these events in the population can be derived as follows: Number of events x 26 (number of two-week periods in a year) x Final Basic Weight = Total number of events occurring in the population during the annual period, i.e. 1996. Example: Number of bed days (Loc. 100-101) x 26 x Final Basic Weight (Loc. 219-227) = total number of bed days reported for the population in 1996. b. The recall period for acute incidence conditions is also two weeks and a national estimate of the total number of acute incidence conditions is calculated using the same procedures as for two-week events for the annual period. Number of acute incidence conditions x 26 x Final Basic Weight = Total number of acute incidence conditions occurring in the population during 1996. Note: An acute incidence condition is an acute condition with onset during the two weeks preceding the date of interview. c. The recall period for information on hospitalizations is 12 months. However, in calculating number of discharges (Locations 132-133, 137-138), only discharges occurring in the past 6 months are counted. Therefore, the weighted estimates must be calculated as follows: Number of discharges x 2 x Final Basic Weight = Total number of discharges occurring in the population in 1996. 7. Calculation of rates for events and conditions: The number of events or conditions estimated for the population, as described in item 6, above, can be used as the basis for calculating rate of occurrence of these events (or conditions) per person and per 100 persons for the total U.S. population and for various population subgroups. Note: Only rates can be estimated from these data. The percent of the population experiencing a particular type of event during the data year cannot be estimated. (The percent of the population experiencing the even in the reporting period (i.e. two weeks or 6 months) can be estimated but is generally not meaningful.) 8. Data on hospital episodes and days, based on a 12-month recall are in locations 122-131. The Final Basic Weight is used for calculating estimates of these events in the same way it is used for all other person-based variables. These variables do permit estimating thepercent of the population in this annual period experiencing a hospital episode in the past year and the percent of that population having a specified number of hospital days. 9. Guidelines for Citation of Data With the goal of mutual benefit, the National Center for Health Statistics (NCHS) requests that recipients of data files cooperate in certain actions related to their use. Any published material derived from the data should acknowledge NCHS as the original source. The suggested citation to appear at the bottom of all tables is as follows: Source: National Center for Health Statistics (1996) When cited in a bibliography, the suggested citation should read: National Center for Health Statistics (1998). Data File Documentation, National Health Interview Survey of Health Insurance, 1996 (machine readable data file and documentation), National Center for Health Statistics, Hyattsville, Maryland. The published material should also include a disclaimer that credits any analyses, interpretations, or conclusions reached to the author (recipient of the data file) and not to NCHS, which is responsible only for the initial data. Consumers who wish to publish a technical description of the data should make a reasonable effort to insure that the description is not inconsistent with that published by NCHS.
