HIV counselling and testing is a key component of both HIV care and HIV prevention, but uptake is currently low. We investigated the impact of rapid HIV testing at the workplace on uptake of voluntary counselling and testing (VCT).
                The study was a cluster-randomised trial of two VCT strategies, with business occupational health clinics as the unit of randomisation. VCT was directly offered to all employees, followed by 2 y of open access to VCT and basic HIV care. Businesses were randomised to either on-site rapid HIV testing at their occupational clinic (11 businesses) or to vouchers for off-site VCT at a chain of free-standing centres also using rapid tests (11 businesses). Baseline anonymised HIV serology was requested from all employees. HIV prevalence was 19.8% and 18.4%, respectively, at businesses randomised to on-site and off-site VCT. In total, 1,957 of 3,950 employees at clinics randomised to on-site testing had VCT (mean uptake by site 51.1%) compared to 586 of 3,532 employees taking vouchers at clinics randomised to off-site testing (mean uptake by site 19.2%). The risk ratio for on-site VCT compared to voucher uptake was 2.8 (95% confidence interval 1.8 to 3.8) after adjustment for potential confounders. Only 125 employees (mean uptake by site 4.3%) reported using their voucher, so that the true adjusted risk ratio for on-site compared to off-site VCT may have been as high as 12.5 (95% confidence interval 8.2 to 16.8).
                High-impact VCT strategies are urgently needed to maximise HIV prevention and access to care in Africa. VCT at the workplace offers the potential for high uptake when offered on-site and linked to basic HIV care. Convenience and accessibility appear to have critical roles in the acceptability of community-based VCT. 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.
                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.
                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.
                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).
                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. HIV voluntary counseling and testing (VCT) may be an effective strategy to prevent transmission of HIV in developing countries. Hypothesizing that primary care services and HIV VCT have synergistic benefits, we examine the feasibility, the demand, and the effect of integrating on-site primary care services into VCT at a stand-alone VCT center in Port au Prince, Haiti.
                Through a retrospective review of patient records, we describe the integration of primary care services at the Groupe Haitien d'Etude du Sarcome de Kaposi et des Infections Opportunistes (GHESKIO) VCT center between1985 and 2000.
                Between 1985 and 1999, services for HIV care, tuberculosis care, treatment of sexually transmitted diseases, and reproductive health were sequentially integrated into HIV VCT at GHESKIO. The number of new people seeking voluntary counseling and testing at GHESKIO increased from 142 in 1985 to 8175 in 1999, with an increasing percentage of women, adolescents, symptom-free clients, and self-referred clients. Of new adults seeking VCT in 1999, the center was able to provide AIDS care to 17%, tuberculosis treatment to 6%, sexually transmitted infection management to 18%, and family planning to 19%. HIV transmission between discordant couples was 0 infections/100 follow-up years (95% CI, 0-3.2); vertical transmission from mother to child was 11 infections/100 live births (95% CI, 4.6-21.9); These rates are significantly lower than expected rates of transmission in Haiti.
                This report demonstrates the feasibility, demand, and effective synergy of integrating on-site primary care services into HIV VCT in Haiti. VCT is a good entry point for people in need of services for communicable diseases and reproductive health, and, reciprocally, services attract more people to VCT, including populations that are at high risk for HIV infection. This program is being duplicated elsewhere in Haiti and can serve as a model for other countries. Our aim was to determine the efficacy of HIV-1 voluntary counselling and testing (VCT) in reducing unprotected intercourse among individuals and sex-partner couples in Nairobi (Kenya), Dar es Salaam (Tanzania), and Port of Spain (Trinidad).
                Individual or couple participants were randomly assigned HIV-1 VCT or basic health information. At first follow-up (mean 7.3 months after baseline) health-information participants were offered VCT and all VCT participants were offered retesting. Sexually transmitted infections were diagnosed and treated at first follow-up. The second follow-up (mean 13.9 months after baseline) involved only behavioural assessment, and all participants were again offered VCT.
                3120 individuals and 586 couples were enrolled. The proportion of individuals reporting unprotected intercourse with non-primary partners declined significantly more for those receiving VCT than those receiving health information (men, 35% reduction with VCT vs 13% reduction with health information; women, 39% reduction with VCT vs 17% reduction with health information), and these results were maintained at the second follow-up. Individual HIV-1-infected men were more likely than uninfected men to reduce unprotected intercourse with primary and non-primary partners, whereas HIV-1-infected women were more likely than uninfected women to reduce unprotected intercourse with primary partners. Couples assigned VCT reduced unprotected intercourse with their enrolment partners significantly more than couples assigned health information, but no differences were found in unprotected intercourse with non-enrolment partners. Couples in which one or both members were diagnosed with HIV-1 were more likely to reduce unprotected intercourse with each other than couples in which both members were uninfected. These changes were replicated by those in the health-information group diagnosed with HIV-1 at first follow-up.
                These data support the efficacy of HIV-1 VCT in promoting behaviour change. Mobile populations are vulnerable to contracting HIV. The present study aims to evaluate the relative efficacy of the voluntary counseling and testing plus information dissemination (VCT-ID) approach versus the information dissemination (ID) approach for promoting HIV preventive behaviors in a mobile population, cross-border truck drivers. A total of 301 adult male cross-border truck drivers who self-reported having had sex with female sex workers (FSW) or non-regular sex partners (NRPs) in mainland China in the last 12 months were recruited and randomized into the VCT-ID intervention group (Group I) or ID control group (Group C). Anonymous structured questionnaires, administered through a computer-assisted method, were used to collect data. At the follow-up survey (about 8-9 weeks since the baseline survey), Group I participants, as compared to Group C participants, were more likely to be consistent condom users when having sex with FSW (85.5% versus 68.5%, p<0.05) and with NRP (54.8% versus 36.4%, p<0.1), more knowledgeable about HIV, and were less likely to have contracted sexually transmitted diseases (STD) in the last two months. The VCT-ID approach is shown to be more efficacious than the ID approach in promoting safer sex and HIV-related knowledge among local cross-border truck drivers. Feasibility of providing voluntary counseling and testing (VCT) services at locations which are convenient to the target population is demonstrated. It also shows that VCT services can be used as a means of HIV prevention. The findings of this study resulted in up-scaled VCT services for the local target population. Governments and donors encourage the integration of family planning into voluntary testing and counselling (VCT) services. We aimed to determine if clients of VCT services have a need for and will accept quality family planning services.
                'Voluntary HIV counselling and testing integrated with contraceptive services' is a proof-of-concept study that interviewed 4019 VCT clients before the addition of family planning services and 4027 different clients after family planning services were introduced. Clients attended eight public VCT facilities in the Oromia region, Ethiopia. The intervention had four components: development of family planning counselling messages for VCT clients, VCT provider training, contraceptive supply provision and monitoring.
                Ethiopia's population of 80 million is increasing rapidly at an annual rate of 2.5%. Contraceptive prevalence is only 15%. The estimated adult HIV prevalence rate is 2.1%, with more than 1.1 million people infected. The number of VCT facilities increased from 23 in 2001 to more than 1000 in 2007, and the number of HIV tests taken doubled from 1.7 million tests in 2007 to 3.5 million in 2008.
                Clients interviewed after the introduction of family planning services received significantly more family planning counselling and accepted significantly more contraceptives than those clients served before the intervention. However, three-quarters of the clients were not sexually active. Of those clients who were sexually active, 70% were using contraceptives.
                The study demonstrated that family planning can be integrated into VCT clinics. However, policy-makers and programme managers should carefully consider the characteristics and reproductive health needs of target populations when making decisions about service integration. HIV voluntary counseling and testing (VCT) programs are usually delivered by government health agencies in China. This study examined the feasibility of using a Chinese non-government organization (NGO) to deliver a VCT program to injection drug users (IDUs) in a southern Chinese city. The process data indicated the program successfully recruited and served 226 male and female IDUs in 4 months. The HIV prevalence rate of the study population was 57.5% by rapid HIV testing with a secondary rapid test to confirm. Quantitative and qualitative evaluations indicated that the VCT program was implemented appropriately and participants' HIV knowledge and safe drug and sex practices were significantly improved after participation in the VCT program. This study demonstrates the feasibility of a Chinese NGO to provide VCT for IDUs and documents the processes and outcomes of the program. There remains a great need to find additional sources to provide VCT and other HIV prevention services to IDUs and other high-risk populations in China. Chinese NGOs have the potential to fill this need. The effectiveness of provider-initiated HIV testing and counseling (PITC) for patients with sexually transmitted infection (STI) in resource-constrained settings are of particular concern for high HIV prevalence countries like South Africa. This study evaluated whether the PITC approach increased HIV testing amongst patients with a new episode of sexually transmitted infection, as compared to standard voluntary counseling and testing (VCT) at the primary care level in South Africa, a high prevalence and low resource setting.
                The design was a pragmatic cluster-controlled trial with seven intervention and 14 control clinics in Cape Town. Nurses in intervention clinics integrated PITC into standard HIV care with few additional resources, whilst lay counselors continued with the VCT approach in control clinics. Routine data were collected for a six-month period following the intervention in 2007, on new STI patients who were offered and who accepted HIV testing. The main outcome measure was the proportion of new STI patients tested for HIV, with secondary outcomes being the proportions who were offered and who declined the HIV test.
                A significantly higher proportion of new STI patients in the intervention group tested for HIV as compared to the control group with (56.4% intervention versus 42.6% control, p = 0.037). This increase was achieved despite a significantly higher proportion intervention group declining testing when offered (26.7% intervention versus 13.5% control, p = 0.0086). Patients were more likely to be offered HIV testing in intervention clinics, where providers offered the HIV test to 76.8% of new STI patients versus 50.9% in the control group (p = 0.0029). There was significantly less variation in the main outcomes across the intervention clinics, suggesting that the intervention also facilitated more consistent performance.
                PITC was successful in three ways: it increased the proportion of new STI patients tested for HIV; it increased the proportion of new STI patients offered HIV testing; and it delivered more consistent performance across clinics. Recommendations are made for increasing the impact and feasibility of PITC in high HIV prevalence and resource-constrained settings. These include more flexible use of clinical and lay staff, and combining PITC with VCT and other community-based approaches to HIV testing.
                Controlled trial ISRCTN93692532. To explore behaviour change, baseline risk behaviour, perception of risk, HIV disclosure and life events in health centre-based voluntary counselling and testing (VCT) clients.
                Single-arm prospective cohort with before-after design at three (one urban and two rural) government health centres in Kenya; study duration 2 years, 1999-2001.
                Consecutive eligible adult clients.
                Numbers of sexual partners, partner type, condom use, reported symptoms of sexually transmitted infection, HIV disclosure and life events.
                High rates of enrollment and follow-up provided a demographically representative sample of 401 clients with mean time to follow-up of 7.5 months. Baseline indicators showed that clients were at higher risk than the general population, but reported a poor perception of risk. Clients with multiple partners showed a significant reduction of sexual partners at follow-up (16% to 6%; p<0.001), and numbers reporting symptoms of sexually transmitted infection decreased significantly also (from 40% to 15%; p<0.001). Condom use improved from a low baseline. Low rates of disclosure (55%) were reported by HIV-positive clients. Overall, no changes in rates of life events were seen.
                This study suggests that significant prevention gains can be recorded in clients receiving health centre-based VCT services in Africa. Prevention issues should be considered when refining counselling and testing policies for expanding treatment programmes.
Although home-based HIV VCT has the potential to enhance VCT uptake in developing countries, insufficient data exist to recommend large-scale implementation of home-based HIV testing. Further studies are needed to determine if home-based VCT is better than facility-based VCT in improving VCT uptake.
