Successful Implementation of Enhanced Recovery After Surgery (ERAS) in Paediatric Cardiac Surgery in Australia

Abstract

Background & Aim

Fast-track or enhanced recovery after surgery (ERAS) is a care pathway for surgical patients based on a multidisciplinary team approach aimed at optimising recovery without increasing risk with protocols based on scientific evidence, which is monitored continuously to ensure compliance and improvement. These protocols have been shown to reduce the duration of postoperative mechanical ventilation and intensive care unit (ICU) length of stay (LOS) following paediatric cardiac surgery. We present the first structured implementation of ERAS in paediatric cardiac surgery in Australia.

Methods

All patients enrolled in the ERAS pathway between October 2019 and July 2023 were identified. Demographic and perioperative data were collected retrospectively from hospital records for patients operated before June 2021 and prospectively from June 2021. A control group (non-ERAS) was identified using propensity matching from patients who underwent similar procedures and were not enrolled in the ERAS pathway (prior to October 2019). Patients were matched for age, weight, and comprehensive Aristotle score. Outcomes of interest were duration of postoperative mechanical ventilation, ICU LOS, readmission to the ICU, hospital LOS, cardiac reintervention rate, postoperative complication rate, and number of 30-day readmissions.

Results

Of 1,084 patients who underwent cardiac surgery during the study period (October 2019–July 2023), 121 patients (11.2%) followed the ERAS pathway. The median age at the time of surgery was 4.8 years (interquartile range [IQR] 2.8–8.8 years). The most common procedure was the closure of atrial septal defect (n=58, 47.9%). The median cardiopulmonary bypass and cross-clamp times were 40 min (IQR 28–53.5 minutes) and 24.5 min (IQR 13–34 minutes) respectively. The majority were extubated in the operating theatre (n=108, 89.3%). The median ICU and hospital LOS were 4.5 hrs (IQR 4.1–5.6 hours) and 4 days (IQR 4–5 days) respectively. None of the patients required readmission to the ICU within 24 hrs of discharge from the ICU. Three (3) patients (2.5%) required reintervention. When compared with the non-ERAS group, the duration of postoperative mechanical ventilation, ICU and hospital LOS were significantly lower in the ERAS group. There was no significant difference in the ICU readmission rate, reintervention rate, complication rate, and number of 30-day readmissions between both groups.

Conclusions

ERAS after paediatric cardiac surgery is feasible and safe in select patients with low preoperative risk. This pathway reduces the duration of postoperative mechanical ventilation, ICU and hospital LOS without increasing risks, enabling the optimisation of resources.
