"Show me the Data": A Recipe for Quality Improvement Success in an Academic Surgical Department.

BACKGROUND: Surgeons in academic medical centers have traditionally taken a siloed approach to reducing postoperative complications. We initiated a project focusing on transparency and sharing of data in order to engage surgeons in collaborative quality improvement. Its key features were the development of a comprehensive Department Quality Dashboard and the creation of a Clinical Operations Council that oversaw quality. The purpose of this study was to assess the impact of those efforts.

STUDY DESIGN: We compared inpatient outcomes before and after our intervention, allowing one quarter as the diffusion period. The outcomes analyzed were: risk-adjusted length of stay (LOS), mortality and direct cost and unadjusted incidence of complications and 30-day all-cause readmissions, as determined by the Vizient Clinical Database. We examined the outcomes of three groups: Group 1 (Surgery), Group 2 - all other surgical departments (Other Surgery) and Group 3 - all other patients (Non-Surgery). Two-tailed Students's t-test was used for analysis and a p value of <0.05 considered statistically significant.

RESULTS: Group 1 demonstrated statistically significant improvements in mortality (p=0.01), LOS (p=0.002), cost (p=0.0001) and complications (p=0.02) while the all-cause readmission rate was unchanged, resulting in mean decrease of 0.55 LOS days and direct cost savings of $2300 per surgical admission. The comparison groups had only modest decreases in some of the analyzed outcomes and an increase in complication rates.

CONCLUSIONS: These data suggest that a collaborative, data-driven and transparent approach to assessing the quality of surgical care can yield significant improvements in patient outcomes.
