The Study of Women's Health Across the Nation (SWAN), is a multisite longitudinal, epidemiologic study designed to examine the health of women during their middle years. The study examines the physical, biological, psychological, and social changes during this transitional period. The goal of SWAN's research is to help scientists, health care providers, and women learn how mid-life experiences affect health and quality of life during aging. The data include questions about doctor visits, medical conditions, medications, treatments, medical procedures, relationships, smoking, and menopause related information such as age at pre-, peri- and post-menopause, self-attitudes, feelings, and common physical problems associated with menopause.

Physician Responses to Medicare Payment Reductions: Impacts on the Public and Private Sectors, 1988-1991 (ICPSR 6563)
Released/updated on: 2024-02-14
Geographic coverage: United States
Time period: 1988-04-01--1991-12-31
The purpose of this study was to investigate the effects on physician behavior of decreases in Medicare payment rates for surgical procedures. The study examined the volume of services provided, billed charges, and the selection of diagnostic or therapeutic alternative procedures, or clinically unrelated procedures, for Medicare and privately-insured patients. Also studied were the proportion of physician income derived from Medicare and the profitability of procedures as they related to the volume of services provided. This data collection comprises observations for 21 surgical procedure groups in the specialty areas of general surgery, gastroenterology, orthopedic surgery, ophthalmology, urology, gynecological surgery, thoracic surgery, and cardiology, from up to 187 hospitals and for up to 15 quarters. Efforts were made to include high volume and expensive procedures. Excluded were radiology, pathology, or other lab procedures, and procedures that had experienced erratic changes in volume due to changes in technology or changes in national standards. Also included in this collection are hospital characteristics and county-level data pertaining to number of hospital beds, per capita income, licensed practical nurse and registered nurse wages, doctors per 1000 population, and health maintenance organization enrollees per 1000 population.

The National Hospital Discharge Survey (NHDS) collects medical and demographic information annually from a sample of hospital discharge records. Variables include patients' demographic characteristics (sex, age, race, marital status), dates of admission and discharge, status at discharge, final diagnoses, surgical and nonsurgical procedures, dates of surgeries, and sources of payment. Information on hospital characteristics such as bedsize, ownership, and region of the country is also included. The medical information is coded using the INTERNATIONAL CLASSIFICATION OF DISEASES, 9TH REVISION, CLINICAL MODIFICATION (ICD-9-CM).

National Medical Expenditure Survey, 1987: Survey of American Indians and Alaska Natives, Preliminary Ambulatory Medical Visit Data [Public Use Tape 23.5P] (ICPSR 6221)
Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 1987-01-01--1987-12-31
The National Medical Expenditure Survey (NMES) series provides 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 Survey of American Indians and Alaska Natives (SAIAN) was designed in collaboration with the Indian Health Service (IHS), and used the same data collection instruments, interview procedures, and time frame as the NMES Household Survey component. However, the SAIAN differed from the Household Survey in several respects. The SAIAN sample was interviewed only three times and was not given the supplements on long-term care, caregiving, and care-receiving. Also, SAIAN respondents were asked additional questions on topics such as use of IHS facilities and traditional medicine, and were given a modified self-administered questionnaire with separate versions for adults and children. Interviewers for the SAIAN were mainly American Indians or Alaska Natives, and about 20 percent of the interviews were not conducted entirely in English. Of these, approximately 40 percent were conducted entirely in the native language of the respondent. Public Use Tape 23.5 provides three data files containing information on the use of and expenditures for ambulatory medical services and sources of payment reported in the SAIAN Survey. 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, a setting other than an inpatient hospital (such as a physician's office, a clinic, or a lab), a nursing home, or a person's home. The first file includes visits and telephone calls to physicians' offices (including HMOs and health departments) in settings other than a hospital or at home, and to providers of care (e.g., chiropractors and psychologists). The second file covers visits to hospital outpatient departments, while the third file provides information on visits to hospital emergency rooms, both regardless of provider type. A record on any of these data files represents a unique ambulatory visit. Variables include dates of visits, medical conditions associated with the visit, types of procedures performed, and the main reason for the visit. In addition, each file contains demographic information such as age, sex, and race.

The 1986 National Mortality Followback Survey (NMFS) is the first National Center for Health Statistics (NCHS) mortality followback study since the 1966-1968 survey of the same name (ICPSR 8370). The 1986 NMFS supplements characteristics of mortality found in the routine vital statistics system by collecting information from death certificate informants or other knowledgeable relatives, and from health care facilities that were used by decedents in the last year of life. The death records provide demographic data on the decedent and information on the circumstances of death (location, time, underlying causes, and other health conditions at time of death) and use of medical facilities in the preceding year. Additional issues addressed in the informant questionnaire were health care sought and provided in the last year of life, risk factors associated with premature death, socioeconomic status and mortality, and reliability of selected items reported on the death certificate. Health care facilities provided information on diagnosis, diagnostic and surgical procedures performed on the decedent, and length of stay.

The survey collected information on usual sources of medical care, sources of medical care utilized, problems associated with access to sources of care, satisfaction with medical services received, utilization of medical diagnostic procedures, health insurance coverage, episodes of illness, and other health-related issues. Additional information collected by the survey includes household composition, age, sex, income, race, education, employment status, and occupation.
