Impact of care pathway adherence on recovery following distal pancreatectomy within an enhanced recovery program

Background: In bowel surgery, adherence to enhanced recovery program (ERP) has been associated with improved recovery. The objective of this study was to evaluate the impact of adherence to ERP elements on outcomes, and identify factors associated with successful recovery following distal pancreatectomy (DP). Methods: Data for 376 patients who underwent DP managed within an ERP including 16 perioperative elements were reviewed. Primary endpoint was successful recovery, a composite outcome defined as length of hospital stay≤7 days, no severe complications nor readmissions. Results: Patients had a mean (SD) overall adherence of 76 (14)%. Overall, 166 (44%) patients had a successful recovery. There was a positive association between overall adherence and successful recovery (OR 1.19, 95%CI 1.08–1.31 for every additional element, p = 0.001), while an inverse relationship was found with comprehensive complication index (8% reduction, 95%CI -15 to −2%, p = 0.011). Adherence to postoperative phase interventions had the greatest impact on recovery (OR 1.29, 95%CI 1.13–1.47 for every additional postoperative element; p < 0.001). At multivariable regression, early termination of IV fluids was the only ERP element associated with successful recovery (OR 2.80, 95%CI 1.73–4.54; p < 0.001). Conclusion: Increased adherence to ERP elements was associated with successful early recovery and reduction of postoperative complication severity.
