Abstract 113: Technical Performance Scores as a quality assessment tool in Congenital Heart Surgery; preliminary analysis of validation data
BACKGROUND : In previous work from our institution, individual practitioner technical performance of surgical procedures has been shown to be an important contributor to outcome and resource utilization in selected congenital cardiac operations. We have developed a Technical Scoring System for evaluation of majority of congenital cardiac procedures and wish to validate its efficacy as a self assessment tool for quality improvement. METHODS : All patients who were discharged between Jan 1 2011 and Dec 31, 2011 were included in this study. Based on discharge echocardiograms, a technical performance score was assigned using previously designed criteria. Case complexity was determined by RACHS-I category, postoperative adverse events and mortality were prospectively monitored. Outcomes were analyzed by non parametric methods. RESULTS : There were a total of 842 discharges encompassing all ages from neonates to adults. 560 (67%) were in RACHS-1 categories 1 to 3 (low risk) and 130 (15%) were in RACHS-1 categories 4 to 6 (high risk) and 152 (18%) could not be categorized. Technical performance scores were as follows: 436 (52%) class 1-optimal, 242(29%) class 2-adequate, 96 (115) class 3-inadequate, and 68(8%) could not classified. Occurrence of major adverse events, mortality and length of stay were all significantly higher in class 3. CONCLUSION : Preliminary data validates the usefulness of the technical scoring system as a quality assessment tool.
