Epidemiology and variability in management of acute mastoiditis in children

摘要

? 2022 Elsevier Inc.Background: To evaluate the epidemiology, management and outcome of acute mastoiditis (AM) in children and to improve strategies for antimicrobial stewardship. Methods: We conducted a retrospective observational study of children aged >6 months to ≤18 years of age admitted to a tertiary care hospital with AM over an 8-year period (2011—2019). Electronic medical records were reviewed to collect data. Results: A total of 129 patients met inclusion criteria for AM during this time period. Eighty-one (63 ) were males with 110 (81 ) White and 67 (52 ) non-Hispanic. The median age at presentation was 6.4 years (3–10.1 years). Ear protrusion was associated with reduced odds of having AM with intracranial extension (ICE) (OR 0.307, 95 CI = 0.107–0.883) whereas presence of headaches and/or neck pain increased the odds of having AM with ICE (OR = 3.96, 95CI 1.29–12.1). The most common etiologies were Streptococcus pyogenes (n = 23, 19.2 ), Pseudomonas aeruginosa (n = 20, 17 ), and Streptococcus pneumoniae (n = 15, 12.5 ). Empiric antibiotic selection and duration of therapy was highly variable. The most common empiric antibiotic used was intravenous vancomycin with a third generation cephalosporin (n = 45, 34.8 ). Majority completed course (n = 92; 73 ) with an oral antibiotic. Shorter (≤10 and ≤14 days) versus longer courses (>10 and >14 days) did not affect readmission rates for AM without ICE. Conclusion: There is high variability of treatment of AM in children. Broad spectrum antibiotics, especially vancomycin were used most frequently despite low rates of Methicillin Resistant Staphylococcus aureus. The use of antibiotic stewardship is essential for judicious antibiotic use.
