Outpatient antibiotic use associated with acute upper respiratory infections in China: a nationwide cross-sectional...

The assessment of antibiotic use for acute upper respiratory infections (AURIs) is important to promote the appropriateness of antibiotic prescribing. Evaluation of antibiotic prescriptions for AURIs at a national level is very limited in China.

To investigate outpatient antibiotic prescriptions for AURIs in Chinese hospitals.

This study used data from over 10 million outpatient and emergency department visits for AURIs, which contained information on drug prescription and diagnosis, from 94 cities and 28 provinces of mainland China. Antibiotic prescription rates for various subgroups and potential predictors of antibiotic use were estimated. Patterns of antibiotic prescriptions and proportions of individual antibiotics prescribed for different types of AURIs were analysed and reported.

In total, 10 770 219 outpatient visits for AURIs were included in this study. Of these, 40.8% (95% confidence interval 40.7-40.8%) resulted in antibiotic prescriptions. Patient characteristics, including age, gender, payment type, AURI type, department and season of visit, were significantly associated with antibiotic prescriptions for AURIs. In total, 4 984 744 antibiotic agents were prescribed, of which 87.9% were broad-spectrum antibiotics and only 36.8% were prescribed in line with the guideline recommendations. Azithromycin (13.2%), cefdinir (11.7%), cefixime (8.3%) and cefaclor (8.2%) were the most commonly prescribed antibiotics for AURIs in China.

Antibiotic prescribing for patients with AURIs in outpatient settings was prevalent nationwide in China. Antibiotic stewardship efforts targeting specific populations in outpatient settings are needed to reduce antibiotic use and promote appropriate antibiotic selection for AURIs in China.
