Brief Summary:
To investigate trends in the incidence and survival rates of congestive heart failure CHF in two successive cohorts of elderly people 1970-74 1990-94 in a health maintenance organization HMO
Detailed Description:
BACKGROUND
The study constituted part of a growing body of research designed to understand not only the secular trends in mortality morbidity survival and disability levels for selected major chronic diseases among older persons in the United States but also the implications of the findings for health care utilization
DESIGN NARRATIVE
The design was that of a retrospective study of successive cohorts of a well-defined and well-documented elderly population for the purpose of identifying and explaining trends in congestive heart failure CHF incidence survival comorbidities and health services utilization during the 25-year period 1970-1994 The study sample consisted of two successive period cohorts of elderly people identified for each of two five-year periods 1970-1974 and 1990-94 The study tested the following hypotheses 1 incidence of CHF had decreased among the younger old 65-74 years of age 2 incidence of CHF had increased among the older old 75 years of age or above 3 one-year survival time had increased following onset of incident CHF and 4 prevalence of hypertension had decreased and prevalence of myocardial infarction and other manifestations of coronary artery disease increased among incident cases of CHF
The study completion date listed in this record was obtained from the End Date entered in the Protocol Registration and Results System PRS record
