Title: Quality indicators of laryngeal cancer care in the elderly.

Abstract: Objective: To examine associations between quality of care, survival, and costs in elderly patients treated for laryngeal squamous cell cancer (SCCA). Study design: Retrospective analysis of Surveillance, Epidemiology, and End Results (SEER)-Medicare data. Methods: We evaluated 2,370 patients diagnosed with laryngeal SCCA from 2004-2007 using multivariate regression and survival analysis. Using quality indicators derived from guidelines for recommended care, summary measures of quality were calculated for diagnosis, initial treatment, surveillance, treatment for recurrent disease, end-of-life care, and performance, and an overall summary measure of quality. Results: High-quality care was associated with significant differences in survival for diagnosis (HR=0.80, 95% CI [0.66-0.97]), initial treatment (HR=0.75 [0.63-0.88]), surveillance (HR=0.54 [0.44-0.66]), treatment of recurrence (HR=1.54 [1.26-1.89]), end-of-life care (HR=0.69 [0.52-0.92]), performance (HR=0.41 [0.33-0.52]), and the overall summary measure of quality (HR=0.66 [0.54-0.80]), which was significantly associated with lower mean incremental costs (-$24,958 [-$35,873- -$14,042]). There was a significant survival advantage for initial treatment with surgery and postoperative radiation (HR=0.66 [0.53-0.82]) and high-volume surgical care (HR=0.64 [0.43-0.96]), after controlling for all other variables including quality of care. Conclusions: High-quality larynx cancer care in elderly patients was associated with improved survival and reduced costs; however, high-quality care for treatment of recurrence was associated with poorer survival. These data suggest that survival outcomes in elderly patients with laryngeal cancer are not entirely explained by differences in the receipt of quality care using existing treatment and performance quality indicators, and suggest a need to develop sensitive and valid quality indicators of larynx cancer care in this population.
