JUANEDA, ERNESTO et al. Quantification of Outcomes in Surgery for Congenital Heart Diseases in 2012-2015: a Four-Year Experience with the International Quality Improvement Collaborative Program. Rev. argent. cardiol. [online]. 2018, vol.86, n.4, pp.10-20. ISSN 1850-3748.

Background: The health care system is undergoing an increasing interest in crossing the quality chasm. Surgery for congenital heart defects has improved in terms of outcomes and quality of life; however, the risk of mortality and infection requires to be quantified. The goal of this study was to quantify the outcomes of surgery for congenital heart diseases following the International Quality Improvement Collaborative (IQIC) for Congenital Heart Disease program.

Methods: This observational and interventional study was conducted at a tertiary children’s hospital in Cordoba, Argentina. Patients undergoing surgery for congenital heart defects between January 1, 2012, and December 31, 2015, were included. The following variables were quantified: sex, age, weight, risk-adjusted congenital heart surgery score, non-adjusted risk, standardized in-hospital mortality ratios and standardized infection ratio (observed rate/expected rate) with their correspond-ing 95% confidence intervals. The results were compared with the IQIC for Congenital Heart Disease program standards (1.0=standardized rates, <1=improvement). The IQIC guidelines based on key drivers -safe perioperative practice, reduction of infections and team-based practice- were implemented as intervention for improvement.

Results: A total of 373 surgical procedures for congenital heart defects were performed on 203 male patients and 170 female patients assigned to the following RACHS-1 categories: I: 28.4%, II: 44%, III: 24.4% and IV-VI 3.2%. Non-adjusted mortality rate at 6 months was of 6%, 3%, 8%, 9%, 11%, 0%, 0% and 5%, respectively (standardized rates 4-6%). Standardized in-hospital mortality ratios and their corresponding confidence intervals were 0.85 (0.23-2.18), 1.82 (0.79-3.59), 1.07 (0.39-2.34), and 0.36 (0.04-1.29), respectively. Non-adjusted infection rate at 6 months was of 4%, 23%, 25%, 14%, 13%, 6%, 9% and 16%, respectively (standardized rates 5-7%).

Conclusion: The implementation of the International Quality Improvement Collaborative for Congenital Heart Disease program with the use of guidelines based on key drivers in a public tertiary hospital in Cordoba, Argentina, contributed to quantifying and improving the outcomes. While mortality decreased, the rate of infections is still to be improved.
