A systematic review of antibiotic utilization in china

Abstract

Objectives: Reliable data about antibiotic utilization in the large pharmaceutical market of the world's most populous country, the People's Republic of China, are in short supply. Although many primary studies have investigated the use of antibiotics in China, mostof the relevant studieswere published in the Chinese language. This systematic review aims to summarize reported percentages of outpatient encounters resulting in the prescription of antibiotics in China. Methods:We systematically searched and reviewed studies of antibiotic prescribing patterns in China, published in Chinese or English between 2000 and August 2012. The study quality was assessed and the overall percentage of outpatient encounters resulting in the prescription of antibiotics was calculated using random-effects metaanalysis. Subgroup analyses were conducted to investigate heterogeneity across studies. Results:We included 57 eligible studies (with a total of 556435 outpatient encounters). The overall percentage of outpatients prescribed antibiotics was 50.3% (95% CI: 47.4%-53.1%). Of the outpatients prescribed antibiotics, 74.0% (95% CI: 71.3%-76.6%) were prescribed one antibiotic, 23.3% (95% CI: 21.1%-25.7%) were prescribed two antibiotics and 2.0% (95% CI: 1.3%-2.8%) were prescribed three or more antibiotics. The proportion of antibiotic utilization differed greatly across hospital levels and geographical regions and fluctuated over time. Conclusions: The percentage use of antibiotics is high in China. The excessive use of antibiotics is particularly more problematic in lower-level hospitals and in less developed western China. The implementation and impact of the national efforts to control the excessive use of antibiotics should be appropriately evaluated. © The Author 2013.
