Microbiological Spectrum of Osteoarticular Infections and Their Management in Mongolian Children.

Introduction. Osteoarticular infections (OI) in children cause considerable morbidity with associated long-lasting sequelae. Comprehensive clinical and microbiological data in Mongolian children are missing. Objectives. To generate epidemiological, clinical and microbiological data on osteoarticular infections (OI) in Mongolian children after the introduction of a standardized management protocol. Methods. A prospective study was done between 2019 and 2022 at the only tertiary pediatric hospital in Mongolia. Results. Forty-two children presented with septic arthritis (SA), 6 with osteomyelitis (OM) and 23 with combined SA and OM. Newborns and young infants (≤3 months) comprised 38.%. A causative organism was identified in 38 children: Staphylococcus aureus (n = 31), Klebsiella spp (n = 3), Enterobacter spp (n = 2), Enterobacter spp + Klebsiella spp (n = 1) and Candida albicans (n = 1). Five children (7%) had sequelae. Mongolian children with OI were younger compared to other cohorts. Conclusion. A standardized protocol for the management of OI in children was taken up well by the patients and treating staff leading to improved pathogen detection, facilitating antimicrobial stewardship in the future.
