Background Antibiotics’ rational prescribing is a major goal of the World Health Organization's (WHO) global action plan to tackle antimicrobial resistance. Evaluation of antibiotic prescribing patterns is necessary to guide simple, globally applicable stewardship interventions. The impact of antimicrobial resistance is devastating, especially in low‐income countries. We aimed to introduce ambulatory data on patterns of paediatric antibiotic prescribing in Jordan, which could be used to guide local stewardship interventions. Methods A cross‐sectional retrospective study was conducted by selecting a random sample of paediatric patients, who attended ambulatory settings in 2018. Records of outpatients (age ≤18 years) receiving at least one antibiotic were included. The WHO’s model of drug utilisation was applied, and all prescribing indicators were included. Multiple linear regression was performed to examine factors influencing the ratio of prescribed antibiotics to overall medications per encounter. Results A total of 20 494 prescriptions, containing 45 241 prescribed drugs, were obtained. The average number of prescribed drugs per prescription was (2.21 ± 0.98). Approximately 77.5% of overall ambulatory prescriptions accounted for antimicrobials. Only 0.6% of total prescriptions were for injectables. All antimicrobials (100%) were prescribed by generic names and from the essential drug list. Antibiotics were most commonly prescribed for respiratory tract infections. Age, gender, season and facility type were significant predictors of prescribed antibiotics to overall medications ratio. Conclusions This is the first study of antibiotic prescribing patterns among outpatient paediatrics that covers wide regions in Jordan. Results indicate high rates of antibiotics use among outpatient paediatrics. Such findings necessitate more focussed efforts and regulations that support rational utilisation of drugs.
