Medicare Current Beneficiary Survey, Calendar Year 1991: [United States] (ICPSR 6118)
Published: Jan 12, 2006
This data collection is the first in a series of data releases planned from the ongoing Medicare Current Beneficiary Survey (MCBS). The MCBS is a continuous, multipurpose survey of a representative sample of the Medicare population. Sample persons are interviewed three times a year over several years to form a continuous profile of their health care experience. Field work for Round 1 began in September of 1991 and was completed in December. New rounds, which involve reinterviewing the same sample persons (or other appropriate respondents), begin every four months. Interviews are conducted regardless of whether the sample person resides at home or in a long-term care facility, using the questionnaire version appropriate to the setting. This first-round interview captured baseline information about the Medicare population, including their demographic characteristics (date of birth, sex, race, education, military service, and marital status), health status and functioning, insurance coverage, financial resources, and family support. Round 1 of the community interview, which questioned respondents living at home, also included a topical supplement on access to medical care, sources of medical care, and satisfaction with medical care.
In preparing the data for this collection, the Health Care Financing Administration (HCFA) has removed all direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, HCFA requires, under Section 1105(a) of the Social Security Act (42 U.S.C., Section 1306(a)) and the Privacy Act (5 U.S.C., Section 552a(1)(3)), that data collected by the HCFA not be used for any purpose other than statistical analysis and reporting. HCFA further requires that analysts not use the data to learn the identity of any persons or establishments and that HCFA 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.
Respondents were sampled from the Medicare enrollment file to be representative of the Medicare population as a whole and by age group: under 45, 45-64, 65-69, 70-74, 75-79, 80-84, and 85 and over. Because of interest in their special health care needs, the oldest old (85 and over) and the disabled (64 and under) were oversampled to permit detailed analysis of these subpopulations. The sample was drawn from 107 primary sampling units (PSUs) chosen to represent the nation, including 41 states, the District of Columbia, and Puerto Rico, with a second stage of 1,163 geographic clusters randomly drawn within those PSUs. The sample is replenished annually for attrition, as well as for newly eligible persons. The Round 1 MCBS sample consisted of 14,530 Medicare beneficiaries, for whom 12,677 interviews were completed. The response rate for the first round was 87 percent, yielding 11,735 community interviews and 942 facility interviews.
