Defining High-Quality Integrated Head and Neck Cancer Care Through a Composite Outcome Measure: Textbook Outcome.

OBJECTIVES/HYPOTHESIS: To further improve the quality of head and neck cancer (HNC) care, we developed a composite measure defined as "textbook outcome" (TO). METHODS: We analyzed a retrospective cohort of patients after curvative-intent primary surgery, radiotherapy (RT), or chemoradiation (CRT) for HNC between 2015 and 2018 at the Netherlands Cancer Institute. TO was defined as 1) the start of treatment within 30 days, 2a) satisfactory pathologic outcomes, without 30-day postoperative complications, for the surgically treated group, and 2b), for RT and CRT patients, no unexpected or prolonged hospitalization and toxicity after the completion of treatment as planned. RESULTS: In total, 392 patients with HNC were included. An overall TO was achieved in 9.6% of patients after surgery, 20.6% after RT, and 2.2% after CRT. Two indicators (margins >5 mm and start treatment <30 days) reduced TO radically for both groups. CONCLUSION: TO can aid the evaluation of the quality of care for HNC patients and guide improvement processes. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:78-87, 2022.
