Background No systematic data on pediatric hospital admissions in Mongolia are available. Methods The Mongolian National Hospital Data registry was screened for pediatric (18 years) hospital admissions (01.01.2019–31.12.2023) to report the prevalence, main diagnoses, and outcomes of hospital admissions in Mongolian newborns, post-neonatal children und 5 years, and children aged 5–17.99 years. Descriptive methods were used for data analysis. Results During the study period, 927,223 pediatric hospital admissions were identified translating into a median prevalence of 5,218 (IQR: 4,386–6,098) pediatric hospital admissions per 100,000 population (all ages) per year. This prevalence was highest among post-neonatal children under 5 years (median: 3,780; IQR: 2,491–3,900), followed by children aged 5–17.99 years (median: 1,945; IQR: 1,929–2,071), and newborns (median: 275; IQR: 246–295) over the study period. Neonatal jaundice was the most frequent main diagnosis in newborns. Pneumonia and COVID-19 were most common in both post-neonatal children under 5 years and children aged 5–17.99 years. The median length of hospital stay was 6.7 (IQR: 5.0–9.0) days in newborns, 6.0 (IQR: 5.0–7.0) days in post-neonatal children under 5 years, and 7.0 (IQR: 5.0–8.0) days in children aged 5–17.99 years. The hospital mortality rate was 5.9% in newborns, 0.25% in post-neonatal children under 5 years, and 0.14% in children aged 5–17.99 years. Conclusions This nationwide, registry-based study found a median prevalence of 5,218 pediatric hospital admissions per 100,000 population (all ages) per year in Mongolia. The majority of pediatric hospital admissions occurred in post-neonatal children under five years. The observation period included the COVID-19 pandemic years.
