HIV/AIDS testing and case analysis in Tianfu New Area of Sichuan Province from 2018 to 2022
Objective To analyze the HIV detection and case discovery in Tianfu New Area of Sichuan Province from 2018 to 2022,and to provide scientific evidence for the formulation of accurate and efficient HIV testing strategies.Methods The data of HIV antibody screening and new case report card were collected from National HIV/AIDS Comprehensive Response Information Management System(CRIMS)in Tianfu New Area from 2018 to 2022,and detection ratio,case detection rate,late detection rate,etc.were analyzed,the comparison of the rate and composition ratio of multiple copies was made by using the chi-square test method,the difference P＜0.05 was considered statistically significant.Results From 2018 to 2022,a total of 1 298 250 person were tested,with an average annual growth rate of 25.80％,and the detection rate of new cases dropped from 1.12％o to 0.43‰(x2trend=117.486,P＜0.001)and the late diagnosis ratio of new cases dropped from 42.95％to 28.86％.(x2trend=4.811,P=0.028).Among the three types of medical institutions,in terms of the amount of testing,primary healthcare institutions had the highest average annual growth rate of 30.42％and the annual rate of decrease of new case detection was the lowest and the biggest portion of 46.56％in terms of accumulative newly reported HIV/AIDS case(x2=204.128,P＜0.001),and the lowest rate was 31.63％in terms of the late diagonosis(x2=8.781,P=0.012).An increasing number of HIV testing was observed in sources such as other sources,outpatients and inpatients,VCT,key populations with average annual growth rate of 56.48％,19.61％,14.96％,12.34％and an decreasing detection rate of new cases was observed in sources of outpatients and inpatients(excluding those from STD clinics),VCT,STD clinics,key populations and other sources(Chi-square trend test all P＜0.05).The lowest of average annual decreased rate was observed in source of outpatients and inpatients.The proportion of late detection in VCT and key population was low,27.16％and 29.63％,respectively.Conclusions The detection of patients in medical institutions is still the main source of new cases,and the primary medical institutions have gradually become the main institutions for the discover of new cases.It would be more likely to detect out new cases from VCT and key populations with lower rate of late diagnosis,detention and STD clinics are the sources of new cases with no decrease in the rate or the decrease is low and the increase of detection volume is low.
