Reporting of Quality Indicators and Improvement in Hospital Performance: The P.Re.Val.E. Regional Outcome Evaluation Program

OBJECTIVE: To evaluate whether reporting of hospital performance was associated with a change in quality indicators in Italian hospitals. DATA SOURCES/STUDY SETTING: Nationwide Hospital Information System for 2006-2009. STUDY DESIGN: We performed a pre-post evaluation in Lazio (before and after disclosure of the Regional Outcome Evaluation Program P.Re.Val.E.) and a comparative evaluation versus Italian regions without comparable programs. We analyzed risk-adjusted proportions of percutaneous coronary intervention (PCI), hip fractures operated on within 48 hours, and cesarean deliveries. DATA COLLECTION/EXTRACTION METHODS: Using standardized ICD-9-CM coding algorithms, we selected 381,053 acute myocardial infarction patients, 250,712 hip fractures, and 1,736,970 women who had given birth. PRINCIPAL FINDINGS: In Lazio PCI within 48 hours changed from 22.49 to 29.43 percent following reporting of the P.Re.Val.E results (relative increase, 31 percent; p < .001). In the other regions this proportion increased from 22.48 to 27.09 percent during the same time period (relative increase, 21 percent; p < .001). Hip fractures operated on within 48 hours increased from 11.73 to 15.78 percent (relative increase, 34 percent; p < .001) in Lazio, and not in other regions (29.36 to 28.57 percent). Cesarean deliveries did not decrease in Lazio (34.57-35.30 percent), and only slightly decreased in the other regions (30.49-28.11 percent). CONCLUSIONS: Reporting of performance data may have a positive but limited impact on quality improvement. The evaluation of quality indicators remains paramount for public accountability.
