Antibiotic Prescribing in Hospitalized Pediatric Patients Before Implementation of a Syndromic Antibiogram at Maputo Central Hospital, Mozambique

Background: Empiric antibiotic prescribing is frequently used in low- and middle-income countries because microbiological diagnostic capacity is often limited, highlighting the need for locally generated microbiological data to support evidence-informed empiric antibiotic selection. However, data on pediatric antibiotic prescribing practices in Mozambique remain scarce. This study aimed to characterize empiric antibiotic prescribing among hospitalized pediatric patients at Maputo Central Hospital prior to the implementation of a syndromic antibiogram intervention. Methods: An exploratory, retrospective, descriptive baseline analysis was conducted among pediatric patients aged 1 month to 14 years admitted with suspected bacterial infections between January and December 2023, prior to the implementation of a syndromic antibiogram intervention. Sociodemographic, clinical, microbiological, and antibiotic prescribing data were extracted from clinical records. Antibiotics were classified according to the WHO AWaRe framework, and associations between patient characteristics, treatment strategies, and outcomes were analyzed using R software version 4.6.0. Results: A total of 358 pediatric patients were included, with a median age of 14 months (IQR: 6–48), and 57% were male. Lower respiratory tract infections were the most frequent diagnosis. Empiric treatment predominated, accounting for 89% of cases, whereas microbiologically guided therapy was observed in only 11%. Urinary tract infections showed significantly higher proportions of microbiologically guided treatment compared with respiratory infections (p < 0.001). Monotherapy predominated, while Watch antibiotics accounted for 64.7% of prescriptions. Prolonged hospitalization was associated with respiratory distress, decreased skin turgor, referral status, infection type, and anemia. Conclusions: Pediatric antibiotic prescribing was characterized by extensive empiric therapy and high Watch antibiotic use, highlighting important antimicrobial stewardship challenges in Mozambique.
