Short-term outcomes and benefits of ERAS program in elderly patients undergoing colorectal surgery: a case-matched study compared to conventional care.

Abstract

The aim of the study was to evaluate the benefits of implementing Enhanced Recovery After Surgery (ERAS) protocols in elderly patients undergoing elective colorectal surgery. A retrospective non-randomized cohort study was conducted from September 2012 to December 2016. We included patients ≥ 70years undergoing elective colorectal surgery. Outcome measures, compliance with interventions, and postoperative complications of patients treated under ERAS were case-matched (based on gender, age, type of surgery, and the presence/absence of a temporal stoma) to a retrospective group of patients ≥ 70years treated under conventional care. A total of 312 patients (156 ERAS vs. 156 non-ERAS) were included in the study. The ERAS group had a significant reduction of grade III/IV Dindo-Clavien's postoperative complications when compared with conventional care. ERAS had a positive effect in reducing anastomotic leakage (14.7% non-ERAS vs. 9%) and postoperative mortality (11.5% non-ERAS vs. 1.9% ERAS; p = 0.001). A reduction of 2days in length of hospital stay was achieved after implementing ERAS (8 (6.75) vs. 6 (5.25); p < 0.0001), while readmission rates remained unaffected. The average of global compliance (GC) with all ERAS interventions was 42%. GC was significantly lower in patients with permanent/temporary stomas and in patients in whom an open approach was performed. In our experience, ERAS should be implemented without reservations in elderly patients expecting the same goals and benefits as with other age groups. Barriers in achieving a high compliance rate are common and will require a great effort in patient's education, an intensive perioperative care, and sometimes a change in the surgeons' practice.
