ObjectiveTo assess the benefit of Enhanced Recovery After Surgery (ERAS) on length of stay (LOS), postoperative complications, 30-day readmission, and cost in gynecologic oncology.MethodsA systematic literature search was performed in MEDLINE, EMBASE, Cochrane Register of Controlled Trials, and Web of Science for all peer-reviewed cohort studies and controlled trials on ERAS involving gynecologic oncology patients. Abstracts, commentaries, non-controlled studies, and studies without specific data on gynecologic oncology patients were excluded. Meta-analysis was performed on the primary endpoint of LOS. Subgroup analyses were performed based on risk of bias of the studies included, number of ERAS elements, and ERAS compliance. Secondary endpoints were readmission rate, complications, and cost.ResultsA total of 31 studies (6703 patients) were included: 5 randomized controlled trials, and 26 cohort studies. Meta-analysis of 27 studies (6345 patients) demonstrated a decrease in LOS of 1.6 days (95% confidence interval, CI 1.2-2.1) with ERAS implementation. Meta-analysis of 21 studies (4974 patients) demonstrated a 32% reduction in complications (OR 0.68, 95% CI 0.55-0.83) and a 20% reduction in readmission (OR 0.80, 95% CI 0.64-0.99) for ERAS patients. There was no difference in 30-day postoperative mortality (OR 0.61, 95% CI 0.23-1.6) for ERAS patients compared to controls. No difference in the odds of complications or reduction in LOS was observed based on number of included ERAS elements or reported compliance with ERAS interventions. The mean cost savings for ERAS patients was $2129 USD (95% CI $712 - $3544).ConclusionsERAS protocols decrease LOS, complications, and cost without increasing rates of readmission or mortality in gynecologic oncology surgery. This evidence supports implementation of ERAS as standard of care in gynecologic oncology.Copyright © 2020 Elsevier Inc. All rights reserved.
