Long-term outcomes of childhood otitis media and hearing loss: a systematic review

Otitis media (OM) is a common childhood illness which can cause hearing loss and developmental delays. This is the first systematic review to investigate the long-term, longitudinal health and social outcomes of OM and hearing loss in childhood. The study was registered in PROSPERO (CRD42023396318). A structured search strategy identified literature in the following databases: CINAHL, Scopus, Medline, PsychInfo, and EmCare. Articles were independently dual-screened and extracted data were synthesised. From 2825 potential studies, 25 were selected for inclusion. These assessed broad outcomes: physical health, audiological health academic, behavioural, social function, service use, and housing. Overall, 28% of papers found no difference between those with a childhood history of OM and those without, 40% found poorer outcomes for those with a history of OM, and 32% found mixed results. This is the first study of its kind to explore the long-term effects of otitis media and resultant hearing loss in children. Trends of poor academic, behavioural, and audiological outcomes were identified in children with OM and hearing loss. Multiple gaps in the literature were identified including a paucity of recent research, studies extending into adulthood, and studies focusing on high-risk populations.
