RESUMO
OBJECTIVES: CMS measures and reports hospital performance to drive quality improvement (QI), but information on actions that hospitals have taken in response to quality measurement is lacking. We aimed to develop national estimates of QI actions undertaken by hospitals and to explore their relationship to performance on CMS quality measures. STUDY DESIGN: Nationally representative cross-sectional survey of acute care hospitals in 2016 (n = 1313 respondents; 64% response rate). METHODS: We assessed 23 possible QI changes. Using multivariate linear regression, we estimated the relationship between reported QI changes and performance on composite measures derived from 26 Hospital Inpatient Quality Reporting Program measures (scaled 0-100), controlling for case mix and facility characteristics. RESULTS: Hospitals reported implementing a mean of 17 QI changes (median [interquartile range], 17 [15-20]). Large hospitals reported significantly higher adoption rates than small hospitals for 18 QI changes. Most hospitals that reported making QI changes (63%-96% for the 23 changes) responded that the specific change made helped improve performance. In multivariate regression analyses, adoption of 92% of QI changes (90th percentile among hospitals), compared with adoption of 50% of QI changes (10th percentile), was associated with a 2.3-point higher overall performance score (95% CI, 0.7-4.0) and higher process (8.7 points; 95% CI, 5.7-11.7) and patient experience (3.0 points; 95% CI, 0.1-5.9) composite scores. CONCLUSIONS: Hospitals reported widespread adoption of QI changes in response to CMS quality measurement and reporting. Higher QI adoption rates were associated with modestly higher process, patient experience, and overall performance composite scores.
