Patient Characteristics Influencing Adherence to Enhanced Recovery Protocols for Colorectal Surgery: a Multicentric Prospective Study.

BACKGROUND: High compliance within enhanced recovery protocols is associated with lower complication rates. Understanding which clinical characteristics make patients more prone to fail adequate adherence to enhanced recovery after surgery guidelines are essential to improve quality care. Our aim was to identify patient characteristics that influence adherence to enhanced recovery protocols in colorectal surgery. METHODS: A total of 1041 patients underwent colorectal surgery under ERPs from September 2017 through December 2017 across 21 institutions in Spain. Demographic, medical, and surgical characteristics of the patients included were extracted to determine their influence on the adherence to enhanced recovery protocols. High adherence was defined as ≥ 73% (median). A univariate analysis was performed initially, followed by multivariable logistic regression analysis. RESULTS: Over 85% of the patients underwent colorectal surgery for cancer resection, of which 12% had metastatic disease. In multivariable model, the presence of coronary artery disease (aOR 1.79, 95% CI 1.12-2.96, p = 0.045) was significantly associated with high adherence to enhanced recovery protocols, while preoperative hypoalbuminemia (aOR 0.55, 95% CI 0.37-0.82, p = 0.003), indication for ostomy (aOR 0.55, 95% CI 0.4-0.75, p < 0.001), and preoperative transfusion (aOR 0.48, 95% CI 0.26-0.91, p = 0.02) were associated with lower adherence. CONCLUSION: In this study, patients that had preoperative transfusions, preoperative hypoalbuminemia, and indication for ostomy were more likely to receive care with less adherence to enhanced recovery protocols elements, while patients with coronary artery disease were more likely to receive more enhanced recovery protocols elements during their hospitalization.
