Improving Surgical Care and Outcomes in Older Cancer Patients Through Implementation of a Pre-Surgical Toolkit (OPTI-Surg)-Final Results of a Phase III Cluster Randomized Trial (Alliance A231601CD).

ABSTRACT

OBJECTIVE: To assess the effect of a practice-level preoperative frailty screening and optimization toolkit (OPTI-Surg) on postoperative functional recovery and complications in elderly cancer patients undergoing major surgery. SUMMARY BACKGROUND DATA Frailty is common in older adults. it increases risk for poor postoperative functional recovery and complications. The potential for a practice-level screening/optimization intervention to improve outcomes is unknown. METHODS: Thoracic, gastrointestinal, and urologic oncological surgery practices within the NCI Community Oncology Research Program (NCORP) were randomized 111, to usual care (UC), OPTI-Surg, or OPTI-Surg with implementation coach. OPTI-Surg consisted of the Edmonton Frail Scale and guided recommendations for referral interventions. Patients ≥70 years old undergoing curative intent surgery were eligible. Primary outcome was 8 weeks postoperative function (kCal/week). Key secondary outcome was complications within 90 days. Mixed models were used to compare UC to the 2 OPTI-Surg arms combined. RESULTS: From 7/2019 to 9/2022, 325 patients were enrolled from 29 practices. 199 (64 UC, 135 OPTI-Surg) and 279 (78 UC, 201 OPTI-Surg) were evaluable for primary and secondary analysis, respectively. UC and OPTI-Surg patients did not significantly differ on total caloric expenditure (2.2 UC, 2.0 OPTI-Surg) after adjusting for baseline function (P=0.53). UC and OPTI-Surg patients did not significantly differ on postoperative complications (25.6% UC, 35.3% OPTI-Surg, P=0.5). CONCLUSIONS: Frailty assessment was successfully performed, but the OPTI-Surg intervention did not improve postoperative function nor reduce postoperative complications compared to UC. Future analysis will explore practice-level factors associated with toolkit implementation and differences between the coaching and non-coaching arms.
