Abstract
Lateral skull base defects (LSBD) pose a diagnostic challenge; however, early recognition and treatment are important to avoid sequelae. This study examines the impact of health care disparities associated with time to diagnosis and treatment for patients with LSBD. Multi-institutional retrospective cohort study at four U.S. tertiary centers from 2000 to 2022. Adult patients with a primary diagnosis of CSF leak or encephalocele were included. Multivariate regressions used to analyze how age, sex, race/ethnicity, insurance, language, zip code, distance to medical center, referral patterns, diagnostic workup, and clinical course affected time to diagnosis and treatment. In 127 patients with LSBD, mean time to treatment of CSF leak or encephalocele was 13.9 months. On average, patients waited 10.6 months from initial assessment to diagnosis and saw 2 providers prior to diagnosis. Approximately 91% (115) of patients had a CT scan, and 75% (95) had an MRI. Imaging did not influence time to treatment. Older age, public insurance, and number of providers seen were associated with delays. Non-English speakers (5% of 127) encountered treatment delays, although this was not statistically significant. Fifty-eight (46%) people had private insurance. The average traveled distance for care was 62.6 miles. Clinical presentation, race, zip code, imaging, myringotomy, beta-2 transferrin, and ED workup were not found to be associated with delays to care. There are significant delays in diagnosis and management of LSBD. Referral patterns did influence care. Health care disparities did not impact care; however, disparities and language barriers need to be studied further to determine contributions to delays in care.
