How well can we identify the high-performing hospital?

Sharing lessons from high-performing hospitals facilitates quality improvement. High-performing hospitals have usually been identified using a small number of performance measures. The objective was to analyze how well 1,006 hospitals performed across a broader range of measures. Five measures were developed from publicly available data: adherence to processes of care, 30-day readmission rates, in-hospital mortality, efficiency, and patient satisfaction. For a subset of hospitals, the authors included two survey-based assessments of patient care quality, one by chief quality officers and one by frontline clinicians. In general, there was little correlation among the publicly available measures (r ≤ .10), though there was notable correlation between objective measures and survey-based measures (r = .23). Hospitals that performed well on a composite measure calculated from the publicly available measures were often not in the top quintile on most individual measures. This highlights the challenge in identifying high-performing hospitals to learn organizational-level best practices.
