Quality improvement intervention to reduce time to postoperative radiation in head and neck free flap patients.

Abstract

Best-practice guidelines for head and neck cancer patients advise postoperative radiation therapy (PORT) initiation within 6 weeks of surgery. We report our institutional experience improving timeliness of adjuvant radiation in free-flap patients. Thirty-nine patients met inclusion criteria in the 2017-2019 study period. We divided into "Early" (n=19) and "Late" (n=20) time-period groups to compare performance over time. The primary endpoint was time to PORT initiation, with success defined as <6 weeks. The number of patients achieving timely PORT improved from 10.5% in the Early group to 50.0% in the Late group (p=0.014). Patients undergoing concurrent adjuvant chemoradiation were more likely to meet the PORT target in the Late group (p=0.012). We ascribe this quality improvement in free-flap patients to increased communication among multidisciplinary care teams, proactive consultation referrals, and a targeted patient-navigator intervention. Though work is needed to further improve performance, insight gained from our experience may benefit other teams.
