Trends in Hospitalization Rates for Heart Failure in the United States, 1973-1986

• Discharge data from a representative sample of short-stay US hospitals were examined to obtain information regarding trends in the prevalence of congestive heart failure from 1973 through 1986. During this 14-year period, the number of discharges more than doubled and the age-adjusted rates increased from 53% to 88% among the four major sex-race groups. On average, nonwhite men experienced annual hospitalization rates 33% higher than white men, while for women the corresponding nonwhite rates were 50% higher. Hospitalization rates during this period remained constant for persons younger than 55 years but rose sharply in the elderly. Concurrently, a slight decline in case fatality rates for an individual hospitalization was seen. The two factors accounting for the growing prevalence of congestive heart failure seem to be the increasing average age of the population and the longer survival of persons with chronic heart disease. The role of Improved medical therapy during the period of this study remains uncertain. Increasing demands to provide care for the congestive heart failure syndrome are likely to continue in the coming years, and medical facilities should develop new intervention strategies to treat or prevent the underlying conditions leading to heart failure as well as decrease the need for hospitalization in this common disorder.
