ABSTRACT
Background: Antimicrobial resistance is a significant clinical problem in pediatric practice in China. Surveillance of antibiotic use is one of the cornerstones to assess the quality of antibiotic use and plan and assess the impact of antibiotic stewardship interventions. Methods: We carried out quarterly point prevalence surveys referring to WHO Methodology of Point Prevalence Survey in 16 Chinese general and children's hospitals in 2019 to assess antibiotic use in pediatric inpatients based on the WHO AWaRe metrics and to detect potential problem areas. Data were retrieved via the hospital information systems on the second Monday of March, June, September and December. Antibiotic prescribing patterns were analyzed across and within diagnostic conditions and ward types according to WHO AWaRe metrics and Anatomical Therapeutic Chemical (ATC) Classification. Results: A total of 22,327 hospitalized children were sampled, of which 14,757 (66.1%) were prescribed ≥1 antibiotic. Among the 3,936 sampled neonates (≤1 month), 59.2% (n = 2,331) were prescribed ≥1 antibiotic. A high percentage of combination antibiotic therapy was observed in PICUs (78.5%), pediatric medical wards (68.1%) and surgical wards (65.2%). For hospitalized children prescribed ≥1 antibiotic, the most common diagnosis on admission were lower respiratory tract infections (43.2%, n = 6,379). WHO Watch group antibiotics accounted for 70.4% of prescriptions (n = 12,915). The most prescribed antibiotic ATC classes were third-generation cephalosporins (41.9%, n = 7,679), followed by penicillins/ß-lactamase inhibitors (16.1%, n = 2,962), macrolides (12.1%, n = 2,214) and carbapenems (7.7%, n = 1,331). Conclusion: Based on these data, overuse of broad-spectrum Watch group antibiotics is common in Chinese pediatric inpatients. Specific interventions in the context of the national antimicrobial stewardship framework should aim to reduce the use of Watch antibiotics and routine surveillance of antibiotic use using WHO AWaRe metrics should be implemented.
ABSTRACT
OBJECTIVES: To assess clinical indication-specific antibiotic prescribing in pediatric practice in China based on the World Health Organization (WHO) Access, Watch, and Reserve (AWaRe) metrics and to detect potential problem areas. STUDY DESIGN: Pediatric prescription records on the 16th of each month during 2018 were sampled for all encounters at outpatient and emergency departments of 16 tertiary care hospitals via hospital information systems. Antibiotic prescribing patterns were analyzed across and within diagnostic conditions according to WHO AWaRe metrics and Anatomical Therapeutic Chemical (ATC) classification. RESULTS: A total of 260â001 pediatric encounters were assessed, and antibiotics were prescribed in 94â453 (36.3%). In 35â167 encounters (37.2%), at least 1 intravenous antibiotic was administered. WHO Watch group antibiotics accounted for 82.2% (n = 84â176) of all antibiotic therapies. Azithromycin (n = 15â791; 15.4%) was the most commonly prescribed antibiotic, and third-generation cephalosporins (n = 44â387; 43.3%) were the most commonly prescribed antibiotic class. In at least 66â098 encounters (70.0%), antibiotics were prescribed for respiratory tract conditions, mainly for bronchitis/bronchiolitis (n = 25â815; 27.3%), upper respiratory tract infection (n = 25â184; 26.7%), and pneumonia (n = 13â392; 14.2%). CONCLUSIONS: Overuse and misuse of WHO Watch group antibiotics for respiratory tract conditions and viral infectious diseases is common in pediatric outpatients in China. Pediatric antimicrobial stewardship should be strengthened using WHO AWaRe metrics.
