National Health Interview Survey, 1973: Prescribed Medicine Supplement (ICPSR 9799)
Principal Investigator(s): United States Department of Health and Human Services. Centers for Disease Control and Prevention. National Center for Health Statistics
The basic purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. Provided with this Prescribed Medication Supplement are variables from the 1973 core Person File (see HEALTH INTERVIEW SURVEY, 1973 [ICPSR 8338]) including items such as sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. This Prescribed Medicine Supplement features information on when, how, and the number of times prescriptions were obtained, and the cost and payment source of prescriptions. The Prescribed Medicine File (Part 1) documents activity restriction, bed disability, work or school loss days, hospitalization days, the number of chronic conditions obtained, and source of payment for medication and care.
These data are available to the general public.
This study is maintained and distributed by the National Archive of Computerized Data on Aging (NACDA), the aging program within ICPSR. NACDA is sponsored by the National Institute on Aging (NIA) at the National Institutes of Heath (NIH).

Scope of Study
Subject Terms: chronic disabilities, chronic illnesses, disabilities, drug costs, health, health care, health care services, health policy, health problems, illness, insurance coverage, prescription drugs
Geographic Coverage: United States
Date of Collection:
Universe: Civilian, noninstitutionalized population of the 50 states and the District of Columbia.
Data Types: clinical data, survey data
Data Collection Notes:
These data files contain weights, which must be used in any analysis.
Per agreement with the National Center for Health Statistics (NCHS), ICPSR distributes the data file(s) and technical documentation in this collection in their original form as prepared by NCHS. In January 1973, the selected number of PSUs in the first stage of sampling changed from 357 to 376 to reflect the 1970 Decennial Census. The segment size changed from six to four households. The data contain ampersands (&), dashes (-), and blank codes.
Sample: Multistage probability design. The first stage selected geographically defined Primary Sampling Units (PSUs) from a total of 1,900 PSUs. There were successive stages, with the final selection being a cluster of neighboring households called a "segment."
Weight: These data contain multiple weight variables for each part. Users should refer to the User Guide for further information regarding the weights and their derivation. Additionally, users may need to weight the data prior to analysis.
Mode of Data Collection: face-to-face interview
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Created online analysis version with question text.
Restrictions: In preparing the data tape(s) for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
