Enhanced Recovery after Surgery (ERAS) pathways in colorectal surgery improve outcomes and reduce disparities, but pathway adherence rates are variable. Sustainability of adherence following initial implementation, particularly in academic settings with trainee involvement, is underexplored. This study measures and describes ERAS adherence for 163 consecutive patients undergoing elective colorectal resection in an academic colorectal surgery department with a well-established ERAS pathway. Providers, including residents and nursing staff, were surveyed regarding pathway knowledge and obstacles to adherence. Adherence was higher preoperatively (80%) and intraoperatively (93%) than postoperatively (61%). Opioid-sparing analgesia and bowel motility agents were underdosed on up to 63% of hospital days, without clinical rationale in ≥50% of cases. Providers cited peer teaching (71%) as the primary source of pathway knowledge and identified individual surgeon preferences as an obstacle to adherence. Formalized ERAS pathway education, communication, and coordination among attending physicians are needed to reduce provider-driven deviation in an academic setting.
