Otitis Media in 2021- What's New?
Dr. Tal Marom, Samson Assuta Ashdod University Hospital
Course Objective
1. To review major interventions aimed to reduce otitis media (OM) burden: OM diagnosis and management guidelines, tympanostomy tubes insertion guidelines, vaccines (pneumococcal conjugate vaccines, influenza, RSV) and continuous medical educational activities.
2. To review time trends in antibiotics treatment policy, in light of local bacteriology and antibiotic resistance patterns.
Course Outline
Otitis media (OM) is a common childhood infection, and a leading cause for increased healthcare utilization, such as frequent office visits, repeated antibiotics prescriptions, and absence from school and parental work. Children with recurrent AOM episodes impose an additional burden, since they are frequently referred to be evaluated for possible hearing loss associated with chronic middle ear effusion and the need for tympanostomy tubes (TT) surgery. Four major efforts have been made to reduce OM burden: 1) publication of OM diagnosis and management guidelines for primary caregivers, 2) publication of indications for TT insertion, 3) introduction of effective new vaccines: pneumococcal conjugate vaccines, influenza and the new-coming RSV vaccine, and 4) educational and teaching activities. These interventions changed the management of OM in ambulatory care and also the presentation of advanced/refractory OM cases and associated complications, such as mastoiditis. Despite the call to adopt a 'watchful waiting' approach in most mild-moderate OM cases, antibiotics administration rates are still high, and in many cases, unnecessary. The bacterial changes have also resulted in the decrease of pneumococcal-OM and a concomitant increase in H. influenzae-OM. The latter infections have a higher rate of treatment failure, due to the production of beta-lactamases. A future switch of the first line therapy for OM from amoxicillin to amoxicillin/clavulanic acid is now under consideration.
