Abstract

Abstract: Background: Identifying and linking barriers to access to head and neck cancer care, specifically provider density, to stage of diagnosis and survival outcomes is important to serve as a foundation for policy interventions. Methods: Retrospective cohort study using patients with head and neck squamous cell (HNSCC) in the Surveillance, Epidemiology, and End Results (SEER) database from 2007 to 2016 and Area Resource File. Primary outcomes included stage of presentation and cancer‐specific 5‐year survival and relation to provider density. Results: The initial cohort consisted of 18 342 patients with oral cavity, 21 809 oropharyngeal, 15 860 laryngeal, and 2887 patients with hypopharyngeal malignancy. Non‐Hispanic Black race and being uninsured increased the odds of presenting with advanced stage HNSCC and increased hazard of death. There was no significant and consistent association identified between Health Service Areas provider density and advanced stage at diagnosis or cancer‐specific 5‐year mortality. Conclusions: Provider density of otolaryngologists and primary care physicians and dentists was not significantly associated with stage of presentation or cancer‐specific survival for HNSCC while race and insurance status remained independent predictors for worse outcomes.
