Incidence and economic burden of acute otitis media in children aged up to 5years in three Middle Eastern countries and Pakistan: A multinational, retrospective, observational study.

Epidemiological data on acute otitis media (AOM), an infectious disease frequently affecting children, are lacking in some countries. This study was undertaken to assess the incidence of AOM in children ≤5years in Saudi Arabia, Oman, Pakistan, and Turkey, as well as the economic burden from a parent/caregiver perspective. Medical records of 4043 children (Saudi Arabia=1023, Oman=998, Pakistan=1022, Turkey=1000) were retrospectively reviewed and the incidence of AOM episodes calculated from suspected and confirmed cases. Using a standardized Health Economics Questionnaire, parents recorded resource use and expenses incurred per AOM episode [in local currency and converted to US dollars (USD)]. The overall incidence of AOM episodes per 1000 person-years was: Saudi Arabia, 207 [95% confidence interval (CI): 178-238]; Oman, 105 (95% CI: 85-127); Pakistan, 138 (95% CI: 116-163); and Turkey, 99 (95% CI: 79-123). The mean total out-of-pocket healthcare expense incurred by parents/caregivers per episode was: Saudi Arabia USD67.1 [standard deviation (SD)=93.0], Oman USD16.1 (SD=16.4), Pakistan USD22.1 (SD=20.5), and Turkey USD33.6 (SD=44.9). The incidence of AOM episodes varied across all four countries, probably due to different diagnostic and management practices. Nevertheless, our results confirm that AOM causes a substantial burden to public health, reinforcing the need for cost-effective prevention strategies.
