Outer and middle ear pathologies are known to disproportionately affect low-income countries but data is limited. We aim to quantify the prevalence rate of patients presenting with middle/outer ear pathologies at ABC Hearing Clinic and Training Centre in Lilongwe, Malawi. Audiological consultations (adult and paediatric) from 2018-2020 were reviewed for outer and middle ear pathologies. Secondary outcomes included patient type (private vs. community) compared to otoscopy findings, tympanometry findings, need for follow up, and follow up compliance. Out of 1576 patients reviewed, the proportion of abnormal cases\' was 98.2%, with 41.4% being unilateral and 57.4% bilateral. Eighty-three percent presented with outer/middle ear pathologies. 68% of those presented with a pathology often associated with some degree of conductive hearing loss (occluding wax, perforation, discharge, Type B/Type C tympanogram). Average age was 29 + 0.527 years; 41.6% private and 58.2% community patients. Cerumen impaction was most common finding (51%). Higher rates of otoscopic abnormalities and type B tympanograms were noted in community vs. private patient (~40% vs. ~30%; ~70% vs. ~30%). Adherence to follow up was higher for community vs. private patients (29% vs. 17%); ~70% reported subjective improvement upon follow up. The majority required multiple interventions on follow up. Secondary follow up was recommended in 64.8%. A significant disease burden of outer and middle ear pathologies was identified. Further research is required to understand the disease burden and promote health policy.

OBJECTIVE: We examined individual-level factors associated with hearing aid use by race and ethnicity in a nationally representative sample of Medicare beneficiaries.
METHODS: We used the Medicare Current Beneficiary Survey (cycles 2016-2018) for 10,301 older adults with hearing loss and hearing aid use as the primary outcome. Covariates included education, income, urban residence, chronic conditions, functional limitations, and Medicaid eligibility. Multivariable logistic regression stratified by race and ethnicity was used to identify factors associated with hearing aid use.
RESULTS: Factors associated with hearing aid use included higher education among White (OR = 1.35, 95%CI:1.16, 1.58), Black (OR = 1.76, 95%CI:1.02, 3.05), and Hispanic (OR = 1.77, 95%CI:1.17, 2.68) beneficiaries. Urban residence was associated with hearing aid use for Black participants (OR = 3.06, 95%CI:1.17, 8.03) and Medicaid eligibility for Hispanic participants (OR = 1.58, 95%CI:0.97, 2.59), although the confidence interval included the null hypothesis.
CONCLUSIONS: ndividual-level factors associated with hearing aid use differed by race and ethnicity among Medicare beneficiaries.
