OBJECTIVE: Increasing complexity of patients referred to cardiac surgery demands more effective heart centers, in order to maintain the same quality. The aim of this study is to examine the short-term effect of adoption of an organizational model on surgical outcomes. METHODS: From January 2006 to June 2007, 367 consecutive adult patients underwent cardiovascular surgery. Pre-, intra- and postoperative data were prospectively collected and transferred to an institutional database. Organizational model was established in August 2006, and based on integrated multiprofessional team work patient-centered, evidence-based medicine with standardized patient care and personal conflict management. The outcomes studied were hospital mortality and combined adverse events (death, stroke, acute myocardial infarction and acute renal failure), by using multivariate logistic regression analysis. RESULTS: After establishment of such model, there was reduction of hospital mortality (from 12% to 3.6%, relative risk= 0.3; P=0.003) and combined events (from 22% to 15%, relative risk=0.68; P=0.11). Operations performed previously to the model were independently associated with higher mortality (OR=2.5; P=0.04), adjusted to preoperative characteristics and Euroscore risk stratification system. Other predictors of mortality were age > 65 years (OR=6.36; 95%CI 2.57 - 17.21; P<0.0001) and cardiopulmonary bypass time > 145 minutes (OR=8.57; 95%CI 3.55 - 21.99; P<0.0001). CONCLUSION: Marked improvements in surgical outcomes depend on development of cardiac surgery centers based on organizational models similar to the model proposed in this study.
