Impact of Enhanced Recovery Program (ERP) on Clinical Outcomes After Elective Colorectal Surgery in a Rural Hospital: A Prospective Cohort Study with Retrospective Control.

Abstract Introduction: The main purpose was to determine the impact on postoperative outcome of a standardized enhanced recovery program (ERP) for elective colorectal surgery in a rural hospital. Methods A prospective series of patients (N = 80) undergoing elective colorectal resection completing a standardized ERP protocol in 2018–2020 (ERP group) was compared to patients (N = 80) operated at the same rural hospital in 2013–2015 (pre-ERP group), before the implementation of the program. The exclusion criteria for both groups were: ASA score IV, TNM stage IV, inflammatory bowel disease, emergency surgery, and rectal cancer. The primary outcome was hospital length of stay (LoS) which was used as an estimate of functional recovery. Secondary outcomes included 30-day readmission and mortality rates as well as factors predicting both postoperative complications and prolonged hospital LoS. Results Baseline characteristics were comparable in both groups. Laparoscopic approach was performed in 95% of patients in the ERP group versus 0% in pre-ERP group. The median adherence to ERP protocol elements was 68% as opposed to 12% in the retrospective control group. The median hospital LoS in the ERP-group was significantly lower than in the pre-ERP group (5 vs. 10 days) with no increase in 30-day readmission and mortality rates. The Body Mass Index ≥ 30 and the traditional perioperative protocol were the independent predictive factors of postoperative complications, while following a traditional peri-operative protocol was the only factor predicting a prolonged hospital LoS. Conclusions Although limited hospital resources are perceived as a barrier to ERP implementation, the current experience demonstrates how adopting an ERP program in a rural area is feasible and effective, despite it requires greater effort. For patients in such areas, colorectal ERP in elective surgery may also reduce time to functional recovery, postoperative hospital LoS and complications, with no increase in mortality and 30-day re-admissions.
