Use of UNAIDS tools to evaluate HIV voluntary counselling and testing services for mineworkers in South Africa

HIV voluntary counselling and testing (VCT) is now an integral part of many HIV care and control programmes. However, very little work has been done to assess the quality of VCT services. An evaluation of VCT services for mineworkers in Welkom, South Africa was conducted to assess client and counsellor satisfaction, the quality of the services and to identify barriers to uptake of VCT. A cross-sectional survey was carried out using tools developed by UNAIDS, consisting of semi-structured interviews and observation of counselling sessions. Twenty-two nurse counsellors and six community volunteers were interviewed. Twenty-four counselling sessions were observed and 24 client exit interviews were conducted. Although nine of the 22 nurse counsellors had only in-service rather than formal training for HIV counselling whereas all community volunteers had been formally trained, nurse counsellors demonstrated better interpersonal skills than did community volunteers. Both clients and counsellors identified fear of a positive result as a major barrier to HIV testing. Clients also raised concerns about confidentiality. UNAIDS evaluation tools were a feasible and an acceptable method of assessing VCT in this operational setting. The study identified areas where training needs to be strengthened and suggested ways of improving the services, and changes to the service have now been implemented in line with these recommendations.     

Introduction of voluntary counselling and rapid testing for HIV in rural South Africa: from theory to practice

Expanding access to voluntary counselling and testing (VCT) for HIV is an important first step in the development of a comprehensive package of HIV services. This article describes the introduction of VCT among five primary health care (PHC) facilities in a rural South African setting, alongside a multidimensional impact assessment as part of a national pilot programme. A baseline review of services demonstrated low levels of VCT, which were predominantly hospital-based. Twenty health workers in five PHC facilities were trained to provide VCT using rapid-testing assays. The feasibility of VCT introduction and its overall acceptability to clients and providers were evaluated using clinic testing registers, semi-structured interviews with counsellors and mock client encounters. One year after its introduction, a major increase in the quantity of HIV testing, the proportion of clients who receive their results, and the proportion who present voluntarily was observed. The majority of those presenting were women, and 20-40 year olds predominated. There was a high level of acceptance among health workers, and the quality of VCT was rated very good in mock client encounters. This work demonstrates one effective model for improving access to VCT through existing primary health care services in a rural South African context.     

Costs and outcomes of VCT delivery models in the context of scaling up services in Indonesia

Objective To evaluate costs and outcomes of voluntary counselling and testing (VCT) service delivery models in urban Indonesia. Methods We collected primary data on utilization, costs and outcomes of VCT services in a hospital clinic (568 clients), HIV community clinic (28 clients), sexually transmitted infection (STI) community clinic (784 clients) and prison clinic (574 clients) in Bandung, Indonesia, in the period January 2008–April 2009. Results The hospital clinic diagnosed the highest proportion and absolute number of HIV infections, but with the lowest average CD4 cell count and with the highest associated travelling and waiting time. The prison clinic detected fewer cases, but at an earlier stage, and all enrolled in HIV care. The community clinics detected the smallest number of cases, and only 0–8% enrolled in HIV care. The unit cost per VCT was highest in the hospital clinic (US$74), followed by the STI community clinic (US$65), the HIV community clinic (US$39) and the prison (US$23). Conclusion We propose a reorientation of the delivery models for VCT and related HIV/AIDS treatment in this setting. We call for the scaling up of community clinics for VCT to improve access, promote earlier detection and to perform (early) treatment activities. This would reduce the burden of the hospital clinic to orient itself towards the treatment of AIDS patients. This is one of very few studies addressing this issue in Asia and the first of its kind in Indonesia, which has a rapidly growing HIV epidemic. The conceptual framework and overall conclusions may be relevant to other low‐income settings.     

HIV and family planning service integration and voluntary HIV counselling and testing client composition in Ethiopia

Integrating voluntary HIV counselling and testing (VCT) with family planning and other reproductive health services may be one effective strategy for expanding VCT service delivery in resource poor settings. Using 30,257 VCT client records with linked facility characteristics from Ethiopian non-governmental, non-profit, reproductive health clinics, we constructed multi-level logistic regression models to examine associations between HIV and family planning service integration modality and three outcomes: VCT client composition, client-initiated HIV testing and client HIV status. Associations between facility HIV and family planning integration level and the likelihood of VCT clients being atypical family planning client-types, versus older (at least 25 years old), ever-married women were assessed. Relative to facilities co-locating services in the same compound, those offering family planning and HIV services in the same rooms were 2-13 times more likely to serve atypical family planning client-types than older, ever-married women. Facilities where counsellors jointly offered HIV and family planning services and served many repeat family planning clients were significantly less likely to serve single clients relative to older, married women. Younger, single men and older, married women were most likely to self-initiate HIV testing (78.2 and 80.6% respectively), while the highest HIV prevalence was seen among older, married men and women (20.5 and 34.2% respectively). Compared with facilities offering co-located services, those integrating services at room- and counsellor-levels were 1.9-7.2 times more likely to serve clients initiating HIV testing. These health facilities attract both standard material and child health (MCH) clients, who are at high risk for HIV in these data, and young, single people to VCT. This analysis suggests that client types may be differentially attracted to these facilities depending on service integration modality and other facility-level characteristics.     

Return to post-test counselling by out-of-treatment injecting drug users participating in a cross-sectional survey in north Vietnam

Return to post-test counselling is essential for optimal individual and public health impact of voluntary counselling and testing (VCT) services. Our study assessed factors associated with return to post-test counselling among 309 out-of-treatment injecting drug users who underwent VCT as part of a cross-sectional survey in Bac Ninh, Vietnam during August and September 2003. The overall return rate to post-test counselling was 54% (n=167). While participants in the rural study district were significantly less likely (chi2=5.8; p<0.05) to return compared with participants in the town centre (42.7 versus 58.1%), return rates did not significantly vary by age, perception of personal HIV risk, HIV serostatus diagnosed by the study, counsellor, history of HIV testing or prior knowledge of HIV status. In a multivariate analysis, higher return rate was associated with residence in Bac Ninh town centre (adjusted OR=1.9; CI=1.1-3.1). Of HIV-positive participants (n=131), 45% (n=59) did not return to collect test results. In view of the findings it is crucial to address risk perception and benefits of collecting test results during pre-test counselling sessions in order to maximize the desired impact of community-based VCT services targeting IDUs in Vietnam.     

Voluntary counselling and testing sites as a source of sentinel information on HIV prevalence in a concentrated epidemic: a pilot project from Indonesia

A new system for monitoring HIV voluntary counselling and testing (VCT) outcomes was established in 2007 at seven VCT clinics in Jakarta and Bali, Indonesia. Counsellors collected demographic and risk information from VCT clients. Logistic regression was used to determine factors associated with HIV infection. In 15 months, HIV prevalence in 5569 new clients without HIV symptoms was 63.3% in injecting drug users (IDUs) (n = 783), 7.7% in female sex workers (n = 1437), 31.6% among transgender people (n = 395), 9.3% in men who have sex with men (n = 268), 13.5% in clients of sex workers (n = 643), 21.1% in people with high-risk partners (n = 569) and 3.2% in other VCT clients (n = 822). Among IDUs, being older, tested though outreach, tested due to being 'at risk' and having injected for one or more years were independently associated with HIV infection. This network confirmed high HIV prevalence among IDUs and transgender people. HIV prevalence estimates were consistent with serosurveys.     

Integration of tuberculosis screening at an HIV voluntary counselling and testing centre in Haiti

OBJECTIVE: To describe the integration of tuberculosis screening into the activities of an HIV voluntary counselling and testing (VCT) centre in a country with endemic tuberculosis. SETTING: An HIV VCT centre in Port au Prince, Haiti. DESIGN: All patients presenting for HIV VCT who reported cough received same-day evaluation for active tuberculosis. Of the 1327 adults presenting to the centre for the first time between January and April 1997, 263 (20%) reported cough and of these 241 (92%) were evaluated. RESULTS: Of the 241 patients evaluated for cough, 76 (32%) were diagnosed with pulmonary tuberculosis. Of the 76 patients diagnosed with pulmonary tuberculosis, 28 (37%) had a positive smear for acid-fast bacilli (AFB), 14 (18%) had a negative AFB smear but a positive sputum culture for Mycobacterium tuberculosis, and 34 (45%) had culture-negative tuberculosis. Also, 31 out of 241 (13%) VCT clients evaluated for cough were diagnosed with bacterial pneumonia. CONCLUSION: This report confirms that in areas with a high HIV and tuberculosis prevalence, a high proportion of VCT clients have active pulmonary tuberculosis. The integration of tuberculosis screening offers several benefits, including the diagnosis and treatment of large numbers of individuals with tuberculosis, a decreased risk of nosocomial tuberculosis transmission, and the opportunity to provide tuberculosis prophylaxis to HIV-positive patients in whom tuberculosis has been excluded. Future studies are needed to determine the cost-effectiveness of integrated tuberculosis and HIV VCT services, and whether integration should be recommended in all countries with high HIV and tuberculosis rates.     

Trends in the uptake of voluntary counselling and testing for HIV in rural Tanzania in the context of the scale up of antiretroviral therapy

Objectives To describe trends in voluntary counselling and testing (VCT) use and to assess whether high‐risk and infected individuals are receiving counselling and learning their HIV status in rural Tanzania. Methods During two rounds of linked serological surveys (2003–2004 and 2006–2007) with anonymous HIV testing among adults, VCT was offered to all participants. The crude and adjusted odds ratios for completing VCT in each survey were calculated to compare uptake by demographic, behavioural and clinical characteristics, stratified by sex. Repeat testing patterns were also investigated. Results The proportion of participants completing VCT increased from 10% in 2003–2004 to 17% in 2006–2007, and among HIV‐infected persons from 14% to 25%. A higher proportion of men than women completed VCT in both rounds, but the difference declined over time. Socio‐demographic and behavioural factors associated with VCT completion were similar across rounds, including higher adjusted odds of VCT with increasing numbers of sexual partners in the past 12 months. The proportion having ever‐completed VCT reached 26% among 2006–2007 attendees, with repeat testing rates highest among those aged 35–44 years. Among 3923 participants attending both rounds, VCT completion in 2006–2007 was 17% among 3702 who were HIV negative in both rounds, 19% among 124 who were HIV infected in both rounds and 22% among 96 who seroconverted between rounds. Conclusion VCT services are attracting HIV‐infected and high‐risk individuals. However, 2 years after the introduction of antiretroviral therapy, the overall uptake remains low. Intensive mobilisation efforts are needed to achieve regular and universal VCT use.     

HIV incidence and risk behaviours after voluntary HIV counselling and testing (VCT) among adults aged 19-35 years living in peri-urban communities around Chiang Mai city in northern Thailand, 1999

The Thai government began HIV voluntary counselling and testing (VCT) in all provinces in 1992. We evaluated HIV incidence after participants utilized VCT and its effect on risk behaviours among northern Thai adults aged 19-35 years. A total of 924 men and 1,327 women volunteered to participate in the study. Subjects were counseled, interviewed (socio-demographic, HIV risk behaviour, and HIV testing history), and tested for HIV infection at baseline and at 6 months follow-up. All participants were provided group pre-test counselling; HIV test results were provided in individual confidential post-test counselling. Overall, 329 of 391 men and 621 of 669 women who reported a prior HIV test before participating in our study reported negative results at the previous test. Of these, nine men and 13 women tested positive at baseline, giving incidence rates of 1.04 and 0.69 per 100 person years (PY), respectively. Recent risk behaviour was rare; as a result, the effects of VCT on risk behaviours among the study participants could not be determined. The HIV incidence after VCT among this study population is substantial. Studies to investigate factors associated with HIV incidence among VCT clients could provide insights for more effective HIV prevention.     

Sociodemographic and clinical characteristics of clients presenting for HIV voluntary counselling and testing in Moshi, Tanzania

HIV voluntary counselling and testing (VCT) reduces high-risk sexual behaviour. Factors associated with HIV infection in VCT clients have not been well characterized in northern Tanzania. We prospectively surveyed 813 VCT clients in Moshi, Tanzania. Clients were administered a questionnaire on sociodemographic characteristics, sexual behaviour, and health status. Blood was taken for rapid HIV antibody testing. Factors associated with HIV seropositivity were identified using multivariate logistic regression analysis. Of 813 clients, the seroprevalence was 16.7%. The strongest associations with seropositivity were reporting diarrhoea (odds ratio [OR] 10.4, 95% confidence interval [CI] 3.6-29.9), an ill sexual partner (OR 6.3, 95% CI 3.0-12.9), or being a woman (OR 3.5, 95% CI 2.0-6.3). In a separate regression, the number of symptoms also predicted HIV infection (OR 2.1, 95% CI 1.6-2.6). VCT clients who tested positive had more HIV-related symptoms suggesting presentation at a later stage of HIV infection.     

HIV incidence during a cluster-randomized trial of two strategies providing voluntary counselling and testing at the workplace, Zimbabwe

OBJECTIVE: To investigate HIV incidence during a trial of two voluntary counselling and testing (VCT) strategies. Counselling may promote beneficial behavioural change, although knowledge of negative status does not appear to contribute further benefit. DESIGN: The parent cluster-randomized trial demonstrated much greater uptake of VCT when counselling and rapid testing were available on-site (intensive VCT) than through pre-paid vouchers to an external provider (standard VCT). Anonymous HIV tests had been requested from all employees at enrolment and after 2 years intervention. METHODS: The study setting was 22 businesses in Harare, Zimbabwe. Participants were 3146 HIV-negative individuals remaining in employment at the end of intervention, of whom 2966 (94.3%) consented to repeat testing. VCT linked to basic HIV care was provided and the main outcome measures were HIV incidence under each study arm, as a retrospective secondary analysis. RESULTS: Mean VCT uptake in this cohort was 70.7 and 5.2%, respectively, in the intensive and standard arms. Crude HIV incidence was 1.21 per 100 person-years, with non-significantly higher rates in the intensive VCT arm [mean site incidence 1.37 and 0.95 per 100 person-years, respectively; adjusted rate ratio 1.49 (95% confidence interval 0.79-2.80). CONCLUSIONS: Highly acceptable VCT did not reduce HIV incidence in this predominantly male cohort. HIV incidence was highest in the high uptake VCT arm, lending support to a US trial in which rapid testing appeared to have adverse behavioural consequences in some HIV-negative clients. Careful comparison of outcomes under different counselling and testing strategies is needed to maximize HIV prevention from global scale-up of VCT.

The meaning and challenge of voluntary counselling and testing (VCT) for counsellors — report of the Kenya Association of Professional Counsellors (KAPC) conference for sub-Saharan Africa

A large number of voluntary counselling and testing (VCT) sites are being opened in sub-Saharan Africa. The services provided by these sites are playing an increasingly important role in the prevention of HIV/AIDS. The sites offer many possibilities and it is crucial that they provide the optimum services for clients. Counselling is an integral part of these services, yet it receives little attention. Counsellors need to be consulted if the optimum services are to be provided, but they are rarely consulted for their professional opinion. Accordingly, the Kenya Association of Professional Counsellors (KAPC) organised a 3-day conference in September 2002 to provide counsellors, drawn from the sub-Saharan region, with a forum to identify VCT-related issues and discuss their implications. The main aim of the conference was for counsellors to arrive at a consensual position regarding HIV/AIDS and what improvements they thought could be made for the VCT services to clients. The counsellors identified the issues that they considered important and this paper presents those issues together with recommendations regarding improvements.     

Predictors of voluntary HIV counselling and testing services utilization among people with disabilities in Addis Ababa,Ethiopia

The study investigated HIV testing prevalence and factors associated with the utilization of voluntary HIV counselling and testing (VCT) services among individuals with disabilities in Addis Ababa. The analysis was based on a survey of 209 men and 203 women with disabilities, aged 15–49, who had ever heard about HIV and AIDS in four sub-cities in Addis Ababa. HIV testing prevalence was 53.2%, with no significant difference between males and females. Comprehensive HIV knowledge, living with spouse, and religious affiliations positively predicted utilization of VCT services among participants. Living with both parents and having physical or mental/intellectual disabilities were negative predictors of VCT services utilization. More research on the predictors of utilization of VCT services by gender and urban/rural divides are needed among people with disabilities.     

Voluntary counselling,HIV testing and adjunctive cotrimoxazole reduces mortality in tuberculosis patients in Thyolo,Malawi

OBJECTIVES: To assess the feasibility and effectiveness of voluntary counselling, HIV testing and adjunctive cotrimoxazole in reducing mortality in a cohort of tuberculosis (TB) patients registered under routine programme conditions in a rural district of Malawi. DESIGN: 'Before' and 'after' cohort study using historical controls. METHODS: Between 1 July 1999 and 30 June 2000 all TB patients were started on standardized anti-TB treatment, and offered voluntary counselling and HIV testing (VCT). Those found to be HIV-positive were offered cotrimoxazole at a dose of 480 mg twice daily, provided there were no contraindications. Side-effects were monitored clinically. End-of-treatment outcomes in this cohort (intervention group) were compared with a cohort registered between 1 July 1998 and 30 June 1999 in whom VCT and cotrimoxazole was not offered (control group). FINDINGS: A total of 1986 patients was registered in the study: 1061 in the intervention group and 925 in the control cohort. In the intervention group, 1019 (96%) patients were counselled pre-test, 964 (91%) underwent HIV testing and 938 (88%) were counselled post-test. The overall HIV-seroprevalence rate was 77%. A total of 693 patients were given cotrimoxazole of whom 14 (2%) manifested minor dermatological reactions. The adjusted relative risk of death in the intervention group compared with the control group was 0.81 (P < 0.001). The number needed to treat with VCT and adjunctive cotrimoxazole to prevent one death during anti-TB treatment was 12.5. INTERPRETATION: This study shows that VCT and adjunctive cotrimoxazole is feasible, safe and reduces mortality rates in TB patients under routine programme conditions.     

Condom use after voluntary counselling and testing in central Mozambique

OBJECTIVE: To evaluate the efficacy of voluntary counselling and testing (VCT) for HIV/AIDS in changing risky sexual behaviour in central Mozambique. METHOD: Longitudinal cohort study of men and women aged at least 18 years from October 2002 to June 2003. We interviewed 622 participants in VCT groups and 598 in non-VCT groups. The interviews occurred before counselling and 4 and 6 months afterwards. RESULTS: Reported use of condoms while having sex with a friends/prostitute increased over each time period in the VCT group and between baseline and first visit in the non-VCT group. Both men and women in the VCT group increased their condom use over time, but the women in the non-VCT group did not. Reported always/sometimes use of condoms for both literate and illiterate subjects was higher and rose over time in the VCT group. CONCLUSION: People who undergo voluntary counselling and testing fro HIV/AIDS change their behaviour, presumably as a result of their counselling.     

Responses to VCT for HIV among young people in Kampala,Uganda

Attitudes to voluntary counselling and testing (VCT) for HIV among young men and women in a slum area of Kampala, Uganda, were studied through 22 individual semi-structured interviews and 5 focus group discussions. Attitudes to VCT ranged from having no problem with the procedure to being very reluctant. Despite fear of stigma, the participants perceived 'positive living' after HIV testing as realistic. VCT was regarded as an important step to avoid HIV infection, but informants expressed the need for the service to be more accessible in terms of cost, time and quality of pre- and post-test counselling. We argue that counselling without HIV testing should be available for those who are reluctant to test. Poverty and gender power imbalances appeared to limit youths' possibility of making rational decisions about sexual behaviour and accessing VCT. The importance of considering the context in which such issues are being negotiated and decided is highlighted.     

Scaling up HIV/AIDS and joint HIV-TB services in Malawi.

Two country-wide surveys were undertaken to assess progress in scaling up human immunodeficiency virus/ acquired immune-deficiency syndrome (HIV/AIDS) and HIV-tuberculosis (TB) services in the public health sector in Malawi between 2002 and 2003. In 2003, 118 sites were performing counselling and HIV testing compared with 70 in 2002. There were 215 269 HIV tests carried out in 2003 compared with 149 540 in 2002, the largest increases being in pregnant women (from 5059 to 26791), patients with TB (from 2130 to 3983) and patients/clients attending health facilities (from 35 407 to 79 584). In 2003, 3703 patients with AIDS were started on antiretroviral therapy compared with 1220 patients in 2002.
