Background: Early discharge (ED) is becoming a crucial component of an enhanced recovery after cardiac surgery (ERACS) program. The aim of this study was to investigate the safety and health resource utilization of an ED pathway implementation in patients undergoing coronary artery bypass grafting and/or valve surgery. Methods: An ED protocol implemented in 2020 used a set of standard de nitions to identify patients eligible for hospital discharge on post-operative days (POD) 3 or 4. Retrospective chart reviews and data collection were conducted. Results: A total of 392 patients were enrolled during the study period. Their median STS mortality risk was 3. 3%, and STS risk for long length of stay was 1. 3%. Half of the patients were discharged to a step-down unit on POD 1. Moreover, 88 (22%) patients were discharged from hospital on POD 3. The rate of re-hospitalization at 30 days was 3. 5%, compared to 4. 7% in a control group of similar patients from 2019. All patients were alive at 30 days. Savings in post-operative hospitalization costs amounted to 2, 923, 200 CAD over the year during the study period. Conclusions: Implementation of an ED protocol can shorten hospital stays without increasing readmission rates while saving costs on post-operative hospitalization. These ndings corroborate previous studies. Telephone monitoring following ED is crucial as it can provide ongoing reassurance on post-operative progress and may help alleviate utilization of emergency services in the early post-operative period.
