Combined benchmarking of hospital outcomes and utilization.

A strong case is made for developing quantitative benchmarks for hospital outcomes as well as utilization that includes both acute care re-admissions and lengths of stay. A number of hospitals in two distinctly different geographic health care environments [CA and NY] are studied as to the differences in outcomes and utilization for three of the most common high-cost DRGs. Unscheduled hospital readmissions (within 30 days of initial discharge) were employed as outcome indicators because they reflect both the quality of acute care and the need for case management in the post-discharge period. Benchmark targets were established for patients with a diagnosis of congestive heart failure, acute MI treated medically, or COPD using scattergrams that showed each hospital's mean acute LOS on the x axis and the re-admission rates on the y axis. "Benchmarks were identified as those points with the lowest values for both indicators, as demonstrated by points that were closest to the intersection of the two axes."
