Impact of enhanced recovery program on clinical outcomes after elective colorectal surgery in a rural hospital. A single center experience.

Background: The main purpose was to determine the impact on postoperative outcomes 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 associated factors with both postoperative complications and prolonged hospital LoS.

Results: Baseline characteristics were comparable in both groups. The median adherence to ERP protocol elements was 68 % versus 12 % in the retrospective control group. The median hospital LoS in the ERP-group was significantly lower than in the pre-ERP group (5 . 10 days) with no increase in 30-day readmission and mortality rates. The Body Mass Index ≥30 and the traditional peri-operative protocol were the associated factors to postoperative complications, while following a traditional peri-operative protocol was the only factor associated with a prolonged hospital LoS (p < 0.0001).

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.
