[Assessment of data quality of intervention in population at high risk for HIV/AIDS in China, 2014-2018]

Objective: To assess the quality of data of intervention in population at high risk for HIV/AIDS, especially in female sex workers (FSWs) and men who have sex with men (MSM), in China during 2014-2018, for the purpose of improving intervention data quality. Methods: Data accuracy was evaluated by sampling monthly reported intervention data and comparing the consistency of the information recorded in national HIV/AIDS prevention and treatment information system to original paper records. Data authenticity was assessed by visiting intervention sites and interviewing owners, manager and/or target groups at sites. The assessment results of both national level and provincial level were summarized by year and analyzed with descriptive statistical method. The data quality problems recognized by assessments were summed up. Results: The annual concordance rate of the data recorded in information system to paper records was 94.6%(17 671/18 673) in provincial level assessment and 79.4%(558/703) in national level assessment. Up to 81.6%(8 617/10 559) and 84.4% (249/295) of all sampled intervention sites were annually evaluated as "good" in provincial and state level assessments respectively. The assessment found that the intervention data in original paper records were not completely consistent to that recorded in the information system, the deficiency of ability on intervention data management, and the insufficient coverage and effect of intervention service influenced the intervention data quality. Conclusions: In general, the accuracy and authenticity of intervention data were fine in China during 2014-2018. Intervention data quality can be improved through measures of enhancing data quality management, strengthening training for the prevention and intervention in FSWs and MSM, and providing high- quality intervention service.
