This report presents the most current nationally representative data on inpatient care in the United States. Data are from the National Hospital Discharge Survey (NHDS), the longest continuously running nationally representative survey of hospital utilization.
As seen in the figure on this page, the length of stay for inpatients has changed dramatically from 1970 through 2003. In 1970, the average length of stay was 7.8 days, with one-third of patients hospitalized for 8 days or more. In 2003, the average length of stay decreased to 4.8 days, with only 16 percent of inpatients staying 8 days or more. During the same period, the percent of patients hospitalized for 3 days or less increased from 36 percent to 57 percent. Length of stay declined despite a significant increase in the average age of hospital inpatients (1).
A number of forces have exerted pressure on the length of hospital stays, including the shift from a Medicare cost-based to a prospective payment system for hospitals in the early 1980s, greater development and coverage of postacute care alternatives to hospitalization, the growth in utilization review programs, and the increased enrollment in managed care programs. Also important were advances in technology and drug therapy (including anesthesia and pain relief) that assisted in

earlier diagnosis and treatment of acute conditions, safer and less invasive surgical interventions, and shorter postoperative recovery times.
