Background: The insufficient knowledge regarding the serological status of people affected with human immunodeficiency virus (HIV) is a concern in Brazil. HIV self-testing (HIVST) has been proved to have great potential for increasing testing, especially among vulnerable populations. The large-scale distribution of HIVST by the Brazilian public health system has increased in recent years. We aimed to investigate the awareness of HIVST among health care providers (HCP) from specialized HIV/AIDS care services in the state of Bahia, Northeast Brazil. Further we investigated HCP acceptability and willingness to offer its use., Methods: A cross-sectional study on HCP from 29 specialized care services (SCS) located in 21 cities in the state of Bahia. HCP working in the service for at least 6 months were included. Sociodemographic, occupational, and behavioral data were collected using a questionnaire. Descriptive statistics were carried out. Bivariate, and multivariate analyses estimating adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) using logistic regression were conducted., Results: The awareness and acceptability of HIVST and the willingness to provide it were 79.8, 55.2, and 47.1%, respectively. Few HCP reported that the SCS where they worked dispensed HIVST (3.6%), and 13.5% received some information or training on HIVST. Factors associated with willingness to offer HIVST were: HIVST acceptability (aOR = 9.45; 95% CI: 4.53-19.71), willingness to use HIVST on themselves (aOR = 4.45; 95% CI: 1.62-12.24), confidence in offering HIVST to clients (aOR = 5.73; 95% CI: 2.26-12.72), and considering everyone eligible for HIVST (aOR = 2.88; 95% CI: 1.25-6.59)., Conclusions: Although most HCP were aware of HIVST, acceptability and willingness to provide it to the clients was moderate. The scale up of HIVST as a mean for the HIV prevention and control policy in Brazil, requires further training of HCP and better implementation of this program., (© 2022. The Author(s).)

Background: Brazil has many people living with HIV (PLWH) who are unaware of their serostatus. The public health system has recently added HIV self-testing (HIVST) for key populations such as men who have sex with men (MSM). This study estimates HIVST acceptability among Brazilian MSM and explores factors associated with acceptability among MSM who have never tested for HIV or who had a previous negative result., Methods: Respondent-driven sampling (RDS) was used to recruit 4176 MSM in 12 Brazilian cities in 2016 to this biological and behavioral surveillance study. We excluded from this analysis all MSM who were aware of their positive HIV serostatus. Descriptive, bivariate and multivariate analyses were conducted. Overall proportions were weighted with Gile's estimator in RDS Analyst software and 95% confidence intervals were calculated. The analyses of HIVST acceptability were stratified by prior HIV testing (never or one or more times)., Results: For this analysis, 3605 MSM were included. The acceptability of HIVST was 49.1%, lower among those who had never tested for HIV (42.7%) compared to those who had a previous HIV negative test (50.1%). In the subgroup of MSM who had never tested for HIV, those who reported discrimination or who had a medical appointment in the last 12 months reported higher HIVST acceptability. Among MSM who had a previous negative HIV test, only those reporting condomless receptive anal sex reported higher HIVST acceptability. In addition, we observed that high levels of knowledge of HIV/AIDS, taking part in lesbian, gay, bisexual, and transgender nongovernmental organizations (LGBT-NGO), or complete secondary or incomplete higher undergraduate education reported higher acceptability., Conclusions: The acceptability of HIVST was low among MSM, especially among those who never tested for HIV. Given access to HIVST in Brazil, we point to the need for programs that enhance promotion of testing addressed to MSM.
