Hospital Variations in Adverse Patient Outcomes

The Medical Collège of Virginia, Department of Health Administration, Virginia Commonwealth University, Box 206, Richmond, VA 23298

Careful review of the literature suggests that the conceptual problem in analyzing hospitals' quality of care is the difficulty of identifying problem domains of hospital care. An appropriate measurement model using multiple indicators of hospital quality problems is developed and evaluated. Adverse patient outcomes reflecting the quality problems are compiled from a peer review organization's generic screen indicators for 85 acute care hospitals. Predictor variables of adverse outcomes include bed size, number of high- technology services offered, case mix, severity of pa tients treated, ownership, net profit, market share, efficiency, teaching status, and metropolitan size. The findings show that hospital characteristics exert lim ited effects on adverse outcomes. Efficiency and av erage length of stay are the only statistically signifi cant factors that explain the variation in adverse outcomes.
