Moreover, HIV testing data from other testing strategies, both pre- and postimplementation of SPARK, were collected to evaluate the capacity of SPARK to increase HIV testing.</p><p><strong>Results: </strong>During this study, MSM testers underwent 10 441 HIV tests; HIV testing volume increased 3-fold from 2020 to 2021. On average, each volunteer recruited 40.99 testers and facilitated 58.99 HIV tests. After SPARK implementation, HIV tests in 2021 increased 1-fold compared with those in 2019; especially for rural MSM testers, the number of HIV tests performed in 2020 and 2021 increased to 2.86 and 5.85 times, respectively, that in 2019. In spatial analysis, most testers sought geographical proximity volunteers for testing; similarly, most testers recruited were from volunteers' own or nearby districts. More than 60% of HIV tests were performed outside of working hours on weekdays, regardless of whether the testers came from urban, periurban, or rural areas.</p><p><strong>Conclusions: </strong>SPARK, an MSM-friendly, geographically accessible, and time-flexible testing strategy, has the potential to promote HIV testing among MSM.</p>","PeriodicalId":19517,"journal":{"name":"Open Forum Infectious Diseases","volume":"11 12","pages":"ofae709"},"PeriodicalIF":3.8,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11639573/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142829459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
