Objective To assess the quality of literatures about healthcare-associated infection (HAI)outbreaks in China in recent 10 years,so as to standardize the research process and reporting methods. Methods HAI outbreak and intervention literature reports published from January 1, 2007 to December 31, 2017 were searched systematically from Wan Fang Database, China National Knowledge Infrastructure (CNKI), two researchers independently screened literatures according to inclusion and exclusion criteria, data were cross-checked and extracted, quality of literature reports was evaluated according to on-line retrieval of information over a network (ORION) statement guidelines. Results A total of 166 literature reports on HAI outbreaks were included in study, with an average ORION score of 5.34. The top three provinces that published the most research were Guangdong (19 studies), Jiangsu (19 studies) and Hubei (18 studies). The top three provinces with higher quality of published study were Guangdong (17.0 points), Shaanxi (13.5 points) and Jiangsu (12.0 points). The main methodological flaws involved:the background of the study was not described in detail(80.72%), the purpose of study were not explained(87.95%), HAI outbreak-related economics research was not carried out (100%) and so on. Conclusion In the past 10 years, literature reports on HAI outbreaks in China are not standardized, and there is much room for quality improvement.
