Abstract:
A pilot cost-of-illness study on long-term complications/sequelae following AOM. Objectives: Acute otitis media (AOM) commonly affects young children and occasionally results in serious complications/sequelae. This pilot cost-of-illness study aimed to assess the economic burden of long-term AOM complications/sequelae in Belgium, and to establish a thorough methodology for a larger study. Methodology: We retrospectively reviewed charts of patients aged 10-20 years with long-term complications/sequelae considered to be AOM-related, and 8 years of follow-up. From a list of 215 eligible patients, we selected 25 patients representing each of seven categories of complications/sequelae. Results: Included patients had a mean age of 12.9 years; nine had chronic suppurative otitis media with cholesteatoma; six sensorineural hearing loss; six chronic perforation of the tympanic membrane; and one each with conductive hear- ing loss, facial paralysis, neurological impairment after intracranial complications, and complications of surgery. During 8-15 years of follow-up, the most common complications were hearing loss, chronic otitis media (OM), and cholesteatoma. These generally occurred >5 years after the firstAOM event, although chronic OM occurred after a mean time of 3.3 years. Yearly public health care payer (PHCP) costs ranged from 119 to 7957 per patient, and were high- est for patients with sensorineural hearing loss. Yearly costs to the patients ranged from 7 to 289 per patient, and were also highest for patients with sensorineural hearing loss. Conclusions: Although complications/sequelae of AOM are rare, they can result in substantial costs. The applied methodology should be feasible for a larger study, with some minor adjustments.
