RESUMEN
OBJECTIVE: Enhanced recovery after cardiac surgery is a multidisciplinary clinical care pathway that relies on a bundle of interventions, aiming to reduce the stress response to surgery and promote early recovery of organ function. In 2011, our institution introduced an institutional enhanced recovery after cardiac surgery program focusing on 9 central interventions, which have been expanded during the past decade by additional interventions now considered standard of care. After the recent publication of the enhanced recovery after cardiac surgery guidelines, we evaluated the relation between the compliance with these enhanced recovery after cardiac surgery guidelines and postoperative outcomes. METHODS: All patients enrolled in our enhanced recovery after cardiac surgery program in 2019 were included in this retrospective single-center audit. The primary outcome was compliance with 23 enhanced recovery after cardiac surgery guidelines. Secondary outcomes included occurrence of at least 1 postoperative complication and hospital length of stay. RESULTS: A total of 356 patients were included in this study. Compliance with the enhanced recovery after cardiac surgery guidelines was 64%. Postoperatively, 51% of the patients experienced at least 1 complication and had a median hospital length of stay of 6 days. Multivariable analysis showed that an increased compliance (per 10%) with the enhanced recovery after cardiac surgery guidelines was associated with a lower risk for any complication (odds ratio, 0.60; 95% confidence interval, 0.46-0.79; P = .0003) and a higher probability of earlier hospital discharge (hazard ratio, 1.25; 95% confidence interval, 1.10-1.43; P = .0008). CONCLUSIONS: This audit revealed a correlation between increased compliance with enhanced recovery after cardiac surgery guidelines and a reduction of postoperative complications and hospital length of stay. Future trials are needed to establish evidence-based recommendations for each separate intervention of the enhanced recovery after cardiac surgery guidelines and to create a minimum core-set of enhanced recovery after cardiac surgery interventions.
