ABSTRACT
Background: Bithermal caloric irrigation, video head impulse test (vHIT), and rotational testing are commonly used to assess peripheral vestibular function, but the relative clinical utility of each test in differentiating patients with peripheral vestibulopathy is debated. Objectives: To determine whether (1) the combination of two or more vestibular tests enhances diagnostic utility over a single test; (2) abnormal test results on vestibular tests correlate with one another. Methods: Retrospective analysis of data collected from multidisciplinary vestibular clinics at two academic medical centers from 2016 to 2022. Results: 150 patients (54.10 ± 15.09 years, 88 females) were included. No individual test was significantly better at predicting the presence of peripheral vestibular damage (p > 0.05). vHIT test results improved significantly when combined with either the caloric test (p = 0.007) or rotary chair test (p = 0.039). Caloric and rotational testing had high sensitivity (74.65% and 76.06%, respectively) and specificity (83.54% and 78.48%, respectively). vHIT demonstrated excellent specificity (89.87%) but poor sensitivity (47.89%). Caloric, vHIT, and rotary chair tests results did not correlate with one another (p > 0.05). Conclusions: Vestibular function tests have comparable diagnostic utility, yet each offers unique advantages. Caloric and rotational testing may be best suited for screening peripheral damage and vHIT may function ideally as a confirmatory test.
ABSTRACT
OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
