Access to Care Pilot for ED-Presenting Head and Neck Cancer Patients (ENRICH-HNC)

Patients diagnosed with head and neck cancer (HNC) after presenting to an emergency department (ED) often face significant delays in diagnosis and treatment. These patients are frequently younger, underinsured, and experience multiple socioeconomic and systems-level barriers to accessing timely cancer care. Delays of more than 30 days have been associated with worse outcomes, including higher recurrence rates and reduced survival. This pilot study will evaluate the feasibility and early impact of a community-based navigation program designed to improve access to timely care for ED-presenting HNC patients. The study embeds trained Community Health Support Specialists (CHSS) from the Engaging Navigators to Reduce Inequities in Cancer Health (ENRICH) program into the ED-to-treatment pathway. After ED discharge, CHSS staff will contact participants by telephone or text message to identify barriers to care-such as transportation, insurance, housing, or communication challenges-and connect them with appropriate community or institutional resources. All participants will receive the CHSS navigation intervention. Outcomes will be compared with a historical cohort of similar ED-presenting HNC patients treated prior to program implementation. The primary outcomes are time from ED discharge to diagnostic biopsy and time from ED discharge to initiation of definitive treatment. Secondary outcomes include feasibility, measured as the proportion of participants who complete CHSS navigation, and exploratory analyses of the types of barriers identified and resolved. Findings from this pilot will generate preliminary data to inform larger studies aimed at improving access, reducing disparities, and accelerating treatment for head and neck cancer patients who first present in the emergency setting.
