Context
Enhanced recovery after surgery (ERAS) protocols aim to improve surgical outcomes by reducing variation in perioperative best practices. However, among published studies, results show a striking variation in the effect of ERAS pathways on perioperative outcomes after cystectomy.
Objective
To perform a systematic review of the literature and a meta-analysis comparing the effectiveness of ERAS versus standard care on perioperative outcomes after cystectomy.
Evidence acquisition
We performed a literature search of PubMed, EMBASE, Web of Science, Google Scholar, the Cochrane Library, and the health-related grey literature in February 2016 according to the Preferred Reporting Items for Systematic Review and Meta-analysis and the Cochrane Handbook. Studies were reviewed according to criteria from the Oxford Centre for Evidence-Based Medicine. Thirteen studies (1493 total patients) met the inclusion criteria (ERAS: 801, standard care: 692). A pooled meta-analysis of all comparative studies was performed using inverse-weighted, fixed-effects models, and random-effects models. Publication bias was graphically assessed using contour-enhanced funnel plots and was formally tested using the Harbord modification of the Egger test.
Evidence synthesis
Pooled data showed a lower overall complication rate (risk ratio [RR]: 0.85, 95% confidence interval [CI]: 0.74–0.97, p = 0.017, I2 = 35.6%), a shorter length of stay (standardized mean difference: −0.87, 95% CI: −1.31 to −0.42, p = 0.001, I2 = 92.8%), and a faster return of bowel function (standardized mean difference: −1.02, 95% CI: −1.69 to −0.34, p = 0.003, I2 = 92.2%) in the ERAS group. No difference was noted for the overall readmission rates (RR: 0.74, 95% CI: 0.39–1.41, p = 0.36, I2 = 51.4%), although a stratified analysis showed a lower 30-d readmission rate in the ERAS group (RR: 0.39, 95% CI: 0.19–0.83, p = 0.015, I2 = 0%).
Conclusions
ERAS protocols reduce the length of stay, time-to-bowel function, and rate of complications after cystectomy.
Patient summary
Enhanced recovery after surgery pathways for cystectomy reduce complications and the amount of time patients spend in the hospital.
