Analysis of HIV testing services provided by MSM community-based organization in Qingdao from 2017 to 2021
Objective To understand the changes in HIV testing services provided by men who have sex with men(MSM)community organizations in Qingdao from 2017 to 2021.Methods HIV testing data and the number of HIV positive cases registered by MSM community organizations in Qingdao from 2017 to 2021 were obtained.Phase A was defined as the period from 2017 to 2019,while the outbreak of a public health emergency(PHE)phase was defined as 2020 to 2021,with Phase B from January to April 2020,and Phase C from May 2020 to December 2021.An ecological research method was employed,and a time-series interrupted model based on the Poisson distribution was established to analyze the changes in the number of HIV tests conducted by MSM community organizations and HIV positivity rates across different phases.Non-parametric tests were used to compare the annual average number of tests and the interval between repeat tests per person across different phases by year.Results The change rate in the number of HIV tests conducted by MSM community organizations in Phase A was 1.011(95％CI:1.005-1.017),indicating an average monthly increase of 1.1％.During phase B,the monthly number of HIV tests performed by MSM community organizations decreased by 58.5％(IRR=0.415,95％CI:0.258-0.668),63.4％(IRR=0.366,95％CI:0.265-0.505),67.8％(IRR=0.322,95％CI:0.237-0.438)and 71.6％(IRR=0.284,95％CI:0.182-0.442)compared to expected levels,respectively.In the first month of phase C,the number of HIV tests recovered to 75.1％(IRR=0.751,95％CI:0.564-1.001)of the expected level,with no significant trend of change thereafter(P＞0.05).From 2017 to 2021,the HIV positive detection rate of MSM community organizations was 4.65％(587/12 624),with 13.01％(41/315)during phase B,showing a significant increase from the expected level(P＜0.05).The interval between repeat HIV tests increased among those tested during the PHE phase compared to phase A(W=137 277,P＜0.001).Conclusions During the PHE phase,there was a decline in the number of HIV tests conducted by MSM community organizations in Qingdao,along with a rise in the HIV positivity rate.MSM community organizations play an important role in the detection of HIV infection,and support for the involvement of MSM community organizations in AIDS prevention and control efforts should be further strengthened in the future.
