Feasibility of community-based HIV self-screening in South Africa: a demonstration project

Background

HIV diagnosis is a critical step in linking HIV-infected individuals to care and treatment and linking HIV-uninfected persons to prevention services. However, the uptake of HIV testing remains low in many countries. HIV self-screening (HIVSS) is acceptable to adults, but there is limited data on HIVSS feasibility in community programmes. This study aimed to evaluate the feasibility of HIVSS in South Africa.

Methods

We conducted a prospective study that enrolled participants through mobile site, homebased, workplace and sex worker programmes in two townships from May to November 2017. Following an information session on HIVSS, interested participants were offered one of three methods of HIVSS testing: supervised, semi-supervised, and unsupervised. Participants who opted for unsupervised testing and those who tested HIV positive after semi- or supervised HIVSS were followed up telephonically or with a home visit one week after receipt of the test kit to confirm results and linkages to care. Follow-up visits were concluded when the participant indicated that they had used the kit or had accessed a confirmatory HIV test.

Results

Of the 2061 people approached, 88.2% (1818/2061) received HIV testing information. Of this group, 89% (1618/1818) were enrolled in the study and 70.0% (1133/1618) were tested for HIV with the kit. The median age was 28 (IQR:23–33) years with an even gender distribution. Of those enrolled, 43.0% (696/1618) were identified through homebased outreach, 42.5% (687/1618) through mobile sites, 7.3% (118/1618) at their workplace and 7.2% (117/1618) from sex worker programmes. A total of 68.7% (1110/1616) selected unsupervised HIVSS, whereas 6.3% (101/1616) opted for semi-supervised and 25.0% ((405/1616) chose supervised HIVSS. Overall, the HIV prevalence using the HIVSS test was 8.2% (93/1129). Of those newly diagnosed with HIV, 16% (12/75) were initiated on ART. Almost half (48.0%; 543/1131) of those tested were linked to a primary HIV test as follows: supervised (85.2%; 336/394); semi-supervised (93.8%; 91/97) and unsupervised (18.1%; 116/640).

Conclusion

Unsupervised HIVSS was by far the most selected and utilised HIVSS method. Linkages to primary and confirmatory testing for the unsupervised HIVSS and further care were low, despite home visits and telephonic reminders.

Are women more likely to self-test? A short report from an acceptability study of the HIV self-testing kit in South Africa

This study assessed the acceptability of, as well as the facilitators of and barriers to the HIV self-testing kit in the Gauteng province, South Africa. An exploratory qualitative cross-sectional study was conducted using focus group discussions (FGDs) among a sample of 118 respondents selected from the Braamfontein and Soweto areas of Johannesburg. Sixteen FGDs were conducted in order to assess the acceptability of the HIV self-testing kit. Respondent groups were segmented according to area (Soweto or Braamfontein), gender (male or female), age (20-34 and 35-49 years of age) and HIV testing status (have previously tested for HIV or have never tested for HIV) in order to achieve maximum variability. The main advantage identified was that the self-testing kit allows for privacy and confidentiality with regard to HIV status, and does not require a visit to a health facility - two of the main barriers to current HIV counselling and testing uptake. However, respondents, predominantly males, were concerned about the lack of counselling involved, which they thought could lead to suicide ideation among testers. The HIV self-testing kit was found to be acceptable among the majority of respondents. However, there is still a need for follow-up services for self-testers. The idea of a hotline for telephonic counselling within the self-testing model seemed to be favourable among many respondents and is an alternative to traditional face-to-face counselling, although some respondents felt that this was not sufficient.

Piloting PrePex for Adult and Adolescent Male Circumcision in South Africa--Pain Is an Issue

BACKGROUND

The World Health Organisation and the Joint United Nations Programme on HIV/AIDS have recommended the scale-up of Medical Male Circumcision (MMC) in countries with high HIV and low MMC prevalence. PrePex device circumcision is proposed as an alternate method for scaling up MMC.

OBJECTIVE

Evaluate safety and feasibility of PrePex in South Africa.

DESIGN

A multisite prospective cohort PrePex study in adults and adolescents at three MMC clinics. Participants were followed-up 8 times, up to 56 days after PrePex placement.

RESULTS

In total, 398 PrePex circumcisions were performed (315 adults and 83 adolescents) their median ages were 26 (IQR: 22-30) and 16 years (IQR: 15-17), respectively. The median time for device placement across both groups was 6 minutes (IQR: 5-9) with the leading PrePex sizes being B (30%) and C (35%) for adults (18-45 years), and A (31%) and B (38%) for adolescents (14-17 years). Additional sizes (size 12-20) were rarely used, even in the younger age group. Pain of device application was minimal but that of removal was severe. However, described pain abated rapidly and almost no pain was reported 1 hour after removal. The Adverse Events rate were experienced by 2.7% (11/398) of all participants, three of which were serious (2 displacements and 1 self-removal requiring prompt surgery). None of the Adverse Events required hospitalization. The majority of participants returned to work within a day of device placement.

CONCLUSION

Our study shows that PrePex is a safe MMC method, for males 14 years and above. PrePex circumcision had a similar adverse event rate to that reported for surgical MMC, but device removal caused high levels of pain, which subsided rapidly.

Perceived risks and benefits of HIV testing, and predictors of acceptance of HIV counselling and testing among pregnant women in Zimbabwe

This project evaluated perceived risks and benefits and determined predictors of acceptance of voluntary HIV counselling and testing (VCT) among pregnant women in Zimbabwe. One hundred and seventy pregnant women attending an urban antenatal clinic were surveyed. Implications of a negative or positive HIV test result and of telling a partner or community members that one is HIV positive were queried. Forty women (23.5%) consented to VCT, and 16 (40%) were HIV positive. Women who saw VCT as lower risk (odds ratio [OR] = 2.3, 95% confidence interval [CI] [1.1-5.0]) and women who had had a stillbirth or child die (OR = 0.4, 95% CI [0.16-0.97]) were more likely to consent. Prenatal HIV VCT offers the best opportunity for prevention of mother-to-child transmission of HIV; however, less than 25% of women consented. If such interventions are to be successful, attention must be directed towards developing culturally appropriate strategies to address women's concerns and improve future acceptance of VCT in Zimbabwe.

The feasibility of voluntary counselling and HIV testing for pregnant women using community volunteers in Zimbabwe

The purpose of this pilot project was to assess the feasibility and acceptability of voluntary counselling and HIV testing (VCT) by pregnant women using community volunteers in Zimbabwe to prevent mother to child transmission (MTCT) of HIV. From July 1999 to June 2001, a short-course zidovudine (ZDV)-based perinatal HIV prevention programme was initiated in two antenatal clinics. Community volunteers, recruited from local community organizations, underwent a two-week training course in VCT, which included HIV/AIDS facts, systematic counselling approach, and practical counselling techniques using scripts and role-play. Rapid HIV testing was performed after informed consent. Lay counsellors conducted individual pre- and post-test counselling for HIV. A total of 35 women community volunteers were trained in VCT; 34 graduated and committed to work four hours per week in the clinic. Of the 6051 pregnant women presenting for antenatal clinics (ANC), 1824 (30%) underwent pre-test counselling and 1547 (26%) were tested, and 429 (28%) were HIV infected. Overall, 1283 (83%) returned for their test results including 406 (95%) of HIV-infected women. Of the 406 HIV-infected women who collected their test results, only 203 (50%) opted for ZDV prophylaxis to prevent MTCT of HIV. Over the two-year study period, two counsellors died and three sought employment at other organizations. Adherence to duty roster was 97% and no breach of confidentiality was reported. Despite many challenges, VCT delivered by community volunteers is feasible and acceptable for pregnant women aiming to reduce their risk of transmitting HIV to their infants. This programme is being implemented at several urban and rural MTCT sites in Zimbabwe and can serve as a model for other resource-poor countries.
