Impacts of health insurance on tympanostomy tube outcomes in the pediatric population.

Abstract

Tympanostomy tube (TT) placement is a common surgical procedure for treating pediatric patients with chronic otitis media with effusion (COME) with or without recurrent acute otitis media (rAOM). Prior work suggests children from low-income families face significant disparities in access to care for rAOM or COME. The impact of these health disparities in the care of children with rAOM or COME has yet to be investigated in a state with an expanded public health insurance model. We seek to examine differences in care for patients with rAOM and COME based on insurance status and socioeconomic status (SES) in Massachusetts. Retrospective review of 560 pediatric patients referred for TT insertion at a tertiary academic medical center between 2017 and 2019. Demographic data collected included age, ethnicity, insurance type (public, private, none) and zip code. Otologic history collected included prior AOM episodes, time to postoperative follow-up, postoperative "no-show" appointments, and number of postoperative audiograms. Multinomial logistic regression was used to isolate the effects of race and ethnicity. We found no major differences in preoperative outcome measures between cohorts. Postoperatively, public insurance was independently associated with decreased odds of undergoing an audiogram (OR 0.35, 95% Cl 0.16-0.76) and increased odds of "no-showing" for an appointment (OR 3.1, 95% CI 1.8-5.3). SES was not independently associated with differences in postoperative outcomes. In a state with an early expanded public health insurance model, access to care for rAOM and COME is comparable despite differences in insurance type and SES. However, enrollment in public health insurance is associated with worse measures of follow up care. Despite improvements in access to care with expanded health insurance models, retention continues to be a challenge for vulnerable populations.
