Defying public expectations: Publicly reported hospital scores do not always correlate with clinical outcomes

Background: Publicly reported hospital scores are used by patients to make health care–related decisions; however, their relationship to clinical outcomes is unknown. Methods: Through the use of the New York Statewide Planning and Research Cooperative System database, the association between two commonly used scores (Healthgrades and Centers for Medicare & Medicaid Services Hospital Compare) and four clinical outcomes was evaluated in several surgical fields (general, colorectal, hepatobiliary, foregut, and bariatric). Results: After adjusting for patient-level factors, patients from facilities with greater Healthgrades scores were less likely to develop any complication after general surgery operations (P = .0013). Also, greater Healthgrades scores were associated with less 30-day readmissions and emergency department visits for general surgery operations only (P = .0061 and P = .0013, respectively). In addition, greater Healthgrades scores were significantly associated with a lesser hospital length of stay for colorectal, foregut, and general surgery operations. Greater Centers for Medicare & Medicaid Services Hospital Compare scores were significantly associated with less 30-day readmissions and lesser hospital length of stay for specific operative groups. Conclusion: Although some specialties demonstrated a correlation, there was no consistent relationship between publicly reported hospital scores and surgical outcomes that contributed to clinically meaningful use for patients or operations.
