Why increasing availability of ART is not enough: a rapid, community-based study on how HIV-related stigma impacts engagement to care in rural South Africa. BMC Public Health 2016; 16:87. [PMID: 26823077 PMCID: PMC4730651 DOI: 10.1186/s12889-016-2753-2] [Citation(s) in RCA: 105] [Impact Index Per Article: 13.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2015] [Accepted: 01/19/2016] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Stigma is a known barrier to HIV testing and care. Because access to antiretroviral therapy reduces overt illness and mortality, some scholars theorized that HIV-related stigma would decrease as treatment availability increased. However, the association between ART accessibility and stigma has not been as straightforward as originally predicted. METHODS We conducted a "situational analysis"--a rapid, community-based qualitative assessment to inform a combination HIV prevention program in high prevalence communities. In the context of this community-based research, we conducted semi-structured interviews and focus groups with 684 individuals in four low-resource sub-districts in North West Province, South Africa. In addition to using this data to inform programming, we examined the impact of stigma on the uptake of services. RESULTS Findings suggested that anticipated stigma remains a barrier to care. Although participants reported less enacted stigma, or hostility toward people living with HIV, they also felt that HIV remains synonymous with promiscuity and infidelity. Participants described community members taking steps to avoid being identified as HIV-positive, including avoiding healthcare facilities entirely, using traditional healers, or paying for private doctors. Such behaviors led to delays in testing and accessing care, and problems adhering to medications, especially for men and youth with no other health condition that could plausibly account for their utilization of medical services. CONCLUSIONS We conclude that providing access to ART alone will not end HIV-related stigma. Instead, individuals will remain hesitant to seek care as long as they fear that doing so will lead to prejudice and discrimination. It is critical to combat this trend by increasing cultural acceptance of being seropositive, integrating HIV care into general primary care and normalizing men and youths' accessing health care.

Abstract
Background Despite large investments in HIV testing, only 45% of HIV-infected persons in sub-Saharan Africa are estimated to know their status. Optimal methods for maximizing population-level testing remain unknown. We sought to demonstrate the effectiveness at achieving population-wide testing coverage of a hybrid mobile HIV testing approach. Methods From 2013–2014, we enumerated 168,772 adult (≥15 years) residents of 32 communities in Uganda (N=20), and Kenya (N=12) using a door-to-door census. “Stable” residence was defined as living in community for ≥6 months over the past year. In each community we performed 2-week multi-disease community health campaigns (CHC) that included HIV testing, counseling, and referral to care if HIV-infected; CHC non-participants were approached for home-based testing (HBT) over 1–2 months. We determined population HIV testing coverage, and predictors of testing via HBT (vs. CHC) and non-testing. Findings HIV testing was achieved in 89% of stable adult residents (131,307/146,906). HIV prevalence was 9.6% (13,043/136,033 stable and non-stable adults); median CD4+ T-cell count was 514 cells/μL (IQR: 355–703). Among stable adults tested, 43% (56,106/131,307) reported no prior testing. Among HIV-infected adults, 38% (4,932/13,043) were unaware of their status. Among stable CHC attendees, 99.5% (104,635/105,170) accepted HIV testing. Of stable adults tested, 80% (104,635/131,307, range: 60–93%) tested via CHCs. In multivariable analyses of stable adults, predictors of non-testing included male gender (risk ratio [RR]: 1.52, 95% CI: 1.48–1.56), single marital status (RR: 1.70, 95% CI: 1.66–1.75), Kenyan residence (RR: 1.46, 95% CI: 1.41–1.50, vs. Ugandan), and out-of-community migration for ≥1 month in past year (RR: 1.60, 95% CI: 1.53–1.68). Testing was more common among farmers (RR: 0.73, 95% CI: 0.67–0.79) and adults with primary education (RR: 0.84, 95% CI: 0.80–0.89). Interpretation High HIV testing coverage was achieved in rural Ugandan and Kenyan communities using a hybrid, mobile approach of multi-disease CHCs followed by HBT. This approach allowed for flexibility at the community and individual level in reaching testing coverage goals. Men and mobile populations remain challenges for universal testing.

Abstract
Little is known about the factors that encourage or discourage refugees to test for HIV, or to access and adhere to HIV care. In non-refugee populations, social support has been shown to influence HIV testing and utilisation of services. The present study enrolled HIV-infected refugees on anti-retroviral therapy (ART) in Uganda, who participated in qualitative interviews on HIV testing, treatment, and adherence. Interviews were analysed for themes about four types of social support: emotional, informational, instrumental, and appraisal support. A total of 61 interviews were analysed. Four roles for these types of social support were identified: (1) informational support encouraged refugees to test for HIV; (2) emotional support helped refugees cope with a diagnosis of HIV; (3) instrumental support facilitated adherence to ART and (4) after diagnosis, HIV-infected refugees provided informational and emotional support to encourage other refugees to test for HIV. These results suggest that social support influences HIV testing and treatment among refugees. Future interventions should capitalise on social support within a refugee settlement to facilitate testing and treatment.

The views and experiences of nurses and midwives in the provision and management of provider-initiated HIV testing and counseling: a systematic review of qualitative evidence. ACTA ACUST UNITED AC 2016; 13:130-286. [PMID: 26767819 DOI: 10.11124/jbisrir-2015-2345] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2015] [Revised: 09/25/2015] [Accepted: 10/22/2015] [Indexed: 10/31/2022]
Abstract
BACKGROUND Global progress towards HIV prevention and care is contingent upon increasing the number of those aware of their status through HIV testing. Provider-initiated HIV testing and counseling is recommended globally as a strategy to enhance uptake of HIV testing and is primarily conducted by nurses and midwives. Research shows that provider-initiated HIV testing and counseling implementation is sub-optimal. The reasons for this are unclear. OBJECTIVES The review aimed to explore nurses' and midwives' views and experiences of the provision and management of provider-initiated HIV testing and counseling. INCLUSION CRITERIA TYPES OF PARTICIPANTS All cadres of nurses and midwives were considered, including those who undertake routine HIV testing as part of a diverse role and those who are specifically trained as HIV counselors. Types of phenomenon of interest: The review sought to understand the views and experiences of the provision and management of provider-initiated HIV testing and counseling (including perceptions, opinions, beliefs, practices and strategies related to HIV testing and its implementation in practice). CONTEXT The review included only provider-initiated HIV testing and counseling. It excluded all other models of HIV testing. The review included all countries and all healthcare settings. Types of studies: This review considered all forms of qualitative study design and methodology. Qualitative elements of a mixed method study were included if they were presented separately within the publication. SEARCH STRATEGY A three-step search strategy was utilized. Eight databases were searched for papers published from 1996 to October 2014, followed by hand searching of reference lists. Only studies published in the English language were considered. METHODOLOGICAL QUALITY Methodological quality was assessed using the Qualitative Assessment and Review Instrument developed by the Joanna Briggs Institute. DATA EXTRACTION Qualitative findings were extracted using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. DATA SYNTHESIS Qualitative research findings were pooled using a pragmatic meta-aggregative approach and the Joanna Briggs Institute Qualitative Assessment and Review Instrument software. RESULTS This review included 21 publications from 18 research studies, representing a wide range of countries and healthcare settings. There were 245 findings which were aggregated into 12 categories and five synthesized findings. 1. Nurses/midwives are supportive of provider-initiated HIV testing and counseling if it is perceived to enhance patient care and to align with perceived professional roles. 2. Nurses'/midwives' ability to perform provider-initiated HIV testing and counseling well requires an appropriate infrastructure and adequate human and material resources. 3. At the organizational level, nurses'/midwives' engagement with provider-initiated HIV testing and counseling is facilitated by an inclusive management structure, alongside the provision of ongoing training and clinical supervision. Provider-initiated HIV testing and counseling is hindered by difficulties in fitting it into existing workloads and routines. 4. Nurses/midwives perceive that good quality care in provider-initiated HIV testing and counseling involves finding a balance between public health needs and individual patient needs. Good care requires time and the ability to apply a patient centred approach. 5. The emotional work involved in provider-initiated HIV testing and counseling can be stressful. Nurses/Midwives may require support to deal with complex moral and ethical issues. CONCLUSIONS This review shows that provider-initiated HIV testing and counseling is supported by nurses/midwives who strive to implement it according to principles of good care and a patient centered approach. Nurses/midwives face multiple operational, infra-structural, resource and ethical challenges in the implementation of provider-initiated HIV testing and counseling. IMPLICATIONS FOR PRACTICE The implementation process for provider-initiated HIV testing and counseling would benefit from using a quality improvement framework. Nurses/midwives undertaking provider-initiated HIV testing and counseling require management support, ongoing training and adequate infrastructure/resources. Additional guidance is required on legal/ethical issues in testing of children and in third party disclosure. IMPLICATIONS FOR RESEARCH Operational research is required to determine an optimal skill mix and optimal methods of integrating provider-initiated HIV testing and counseling into existing work routines.

Abstract
OBJECTIVE To examine the associations between perceived quality of care and patient satisfaction among HIV and non-HIV patients in Zambia. SETTING Patient exit survey conducted at 104 primary, secondary and tertiary health clinics across 16 Zambian districts. PARTICIPANTS 2789 exiting patients. PRIMARY INDEPENDENT VARIABLES Five dimensions of perceived quality of care (health personnel practice and conduct, adequacy of resources and services, healthcare delivery, accessibility of care, and cost of care). SECONDARY INDEPENDENT VARIABLES Respondent, visit-related, and facility characteristics. PRIMARY OUTCOME MEASURE Patient satisfaction measured on a 1-10 scale. METHODS Indices of perceived quality of care were modelled using principal component analysis. Statistical associations between perceived quality of care and patient satisfaction were examined using random-effect ordered logistic regression models, adjusting for demographic, socioeconomic, visit and facility characteristics. RESULTS Average satisfaction was 6.9 on a 10-point scale for non-HIV services and 7.3 for HIV services. Favourable perceptions of health personnel conduct were associated with higher odds of overall satisfaction for non-HIV (OR=3.53, 95% CI 2.34 to 5.33) and HIV (OR=11.00, 95% CI 3.97 to 30.51) visits. Better perceptions of resources and services were also associated with higher odds of satisfaction for both non-HIV (OR=1.66, 95% CI 1.08 to 2.55) and HIV (OR=4.68, 95% CI 1.81 to 12.10) visits. Two additional dimensions of perceived quality of care--healthcare delivery and accessibility of care--were positively associated with higher satisfaction for non-HIV patients. The odds of overall satisfaction were lower in rural facilities for non-HIV patients (OR 0.69; 95% CI 0.48 to 0.99) and HIV patients (OR=0.26, 95% CI 0.16 to 0.41). For non-HIV patients, the odds of satisfaction were greater in hospitals compared with health centres/posts (OR 1.78; 95% CI 1.27 to 2.48) and lower at publicly-managed facilities (OR=0.41, 95% CI=0.27 to 0.64). CONCLUSIONS Perceived quality of care is an important driver of patient satisfaction with health service delivery in Zambia.

Abstract
HIV/AIDS, a chronic burden in Ghana, poses social and health outcome concerns to those infected. Examining the Medical Outcome Study Social Support Survey (MOS-SSS) instrument among 300 Ghanaians from a cross-sectional design, Principal Component Analysis yielded four factors (positive interaction, trust building, information giving, and essential support), which accounted for 85.73% of the total variance in the MOS-SSS. A logistic regression analysis showed that essential support was the strongest predictor of the length of time an individual stayed in the support group, whereas positive interaction indicated negative association. The study's implications for policy, research, and practice were discussed.

Systematic review and meta-analysis of community and facility-based HIV testing to address linkage to care gaps in sub-Saharan Africa. Nature 2015; 528:S77-85.

Abstract
HIV testing and counselling is the first crucial step for linkage to HIV treatment and prevention. However, despite high HIV burden in sub-Saharan Africa, testing coverage is low, particularly among young adults and men. Community-based HIV testing and counselling (testing outside of health facilities) has the potential to reduce coverage gaps, but the relative impact of different modalities is not well assessed. We conducted a systematic review of HIV testing modalities, characterizing community (home, mobile, index, key populations, campaign, workplace and self-testing) and facility approaches by population reached, HIV positivity, CD4 count at diagnosis and linkage. Of 2,520 abstracts screened, 126 met eligibility criteria. Community HIV testing and counselling had high coverage and uptake and identified HIV-positive people at higher CD4 counts than facility testing. Mobile HIV testing reached the highest proportion of men of all modalities examined (50%, 95% confidence interval (CI) = 47-54%) and home with self-testing reached the highest proportion of young adults (66%, 95% CI = 65-67%). Few studies evaluated HIV testing for key populations (commercial sex workers and men who have sex with men), but these interventions yielded high HIV positivity (38%, 95% CI = 19-62%) combined with the highest proportion of first-time testers (78%, 95% CI = 63-88%), indicating service gaps. Community testing with facilitated linkage (for example, counsellor follow-up to support linkage) achieved high linkage to care (95%, 95% CI = 87-98%) and antiretroviral initiation (75%, 95% CI = 68-82%). Expanding home and mobile testing, self-testing and outreach to key populations with facilitated linkage can increase the proportion of men, young adults and high-risk individuals linked to HIV treatment and prevention, and decrease HIV burden.

Abstract
OBJECTIVES Despite substantial public health efforts to increase HIV testing, testing rates have plateaued in many countries and rates of repeat testing for those with ongoing risk are low. To inform policies aimed at increasing uptake of HIV testing, we identified characteristics associated with individuals' willingness-to-accept (WTA) an HIV test in a general population sample and among two high-risk populations in Moshi, Tanzania. METHODS In total, 721 individuals, including randomly selected community members (N = 402), female barworkers (N = 135), and male Kilimanjaro mountain porters (N = 184), were asked in a double-bounded contingent valuation format if they would test for HIV in exchange for 2000, 5000 or 10,000 Shillings (approximately $1.30, $3.20, and $6.40, respectively). The study was conducted between September 2012 and February 2013. RESULTS More than one quarter of participants (196; 27 %) stated they would be willing to test for Tanzania Shilling (TSH) 2000, whereas one in seven (98; 13.6 %) required more than TSH 10,000. The average WTA estimate was TSH 4564 (95 % Confidence Interval: TSH 4201 to 4927). Significant variation in WTA estimates by gender, HIV risk factors and other characteristics plausibly reflects variation in individuals' valuations of benefits of and barriers to testing. WTA estimates were higher among males than females. Among males, WTA was nearly one-third lower for those who reported symptoms of HIV than those who did not. Among females, WTA estimates varied with respondents' education, own and partners' HIV testing history, and lifetime reports of transactional sex. For both genders, the most significant association was observed with respondents' perception of the accuracy of the HIV test; those believing HIV tests to be completely accurate were willing to test for approximately one third less than their counterparts. The mean WTA estimates identified in this study suggest that within the study population, incentivized universal HIV testing could potentially identify undiagnosed HIV infections at an incentive cost of $150 per prevalent infection and $1400 per incident infection, with corresponding costs per quality adjusted life year (QALY) gained of $70 for prevalent and $620 for incident HIV infections. CONCLUSIONS The results support the value of information about the accuracy of HIV testing, and suggest that relatively modest amounts of money may be sufficient to incentivize at-risk populations to test.

Abstract
INTRODUCTION Remarkable strides have been made in controlling the HIV epidemic, although not enough to achieve epidemic control. More recently, interest in biomedical HIV control approaches has increased, but substantial challenges with the HIV cascade of care hinder successful implementation. We summarise all available HIV prevention methods and make recommendations on how to address current challenges. DISCUSSION In the early days of the epidemic, behavioural approaches to control the HIV dominated, and the few available evidence-based interventions demonstrated to reduce HIV transmission were applied independently from one another. More recently, it has become clear that combination prevention strategies targeted to high transmission geographies and people at most risk of infections are required to achieve epidemic control. Biomedical strategies such as male medical circumcision and antiretroviral therapy for treatment in HIV-positive individuals and as pre-exposure prophylaxis in HIV-negative individuals provide immense promise for the future of HIV control. In resource-rich settings, the threat of HIV treatment optimism resulting in increased sexual risk taking has been observed and there are concerns that as ART roll-out matures in resource-poor settings and the benefits of ART become clearly visible, behavioural disinhibition may also become a challenge in those settings. Unfortunately, an efficacious vaccine, a strategy which could potentially halt the HIV epidemic, remains elusive. CONCLUSION Combination HIV prevention offers a logical approach to HIV control, although what and how the available options should be combined is contextual. Therefore, knowledge of the local or national drivers of HIV infection is paramount. Problems with the HIV care continuum remain of concern, hindering progress towards the UNAIDS target of 90-90-90 by 2020. Research is needed on combination interventions that address all the steps of the cascade as the steps are not independent of each other. Until these issues are addressed, HIV elimination may remain an unattainable goal.

Wiklander M, Brännström J, Svedhem V, Eriksson LE. Development and psychometric testing of a barriers to HIV testing scale among individuals with HIV infection in Sweden; The Barriers to HIV testing scale-Karolinska version. Health Qual Life Outcomes 2015; 13:185. [PMID: 26584977 PMCID: PMC4653894 DOI: 10.1186/s12955-015-0381-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2015] [Accepted: 11/14/2015] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Barriers to HIV testing experienced by individuals at risk for HIV can result in treatment delay and further transmission of the disease. Instruments to systematically measure barriers are scarce, but could contribute to improved strategies for HIV testing. Aims of this study were to develop and test a barriers to HIV testing scale in a Swedish context. METHODS An 18-item scale was developed, based on an existing scale with addition of six new items related to fear of the disease or negative consequences of being diagnosed as HIV-infected. Items were phrased as statements about potential barriers with a three-point response format representing not important, somewhat important, and very important. The scale was evaluated regarding missing values, floor and ceiling effects, exploratory factor analysis, and internal consistencies. RESULTS The questionnaire was completed by 292 adults recently diagnosed with HIV infection, of whom 7 were excluded (≥9 items missing) and 285 were included (≥12 items completed) in the analyses. The participants were 18-70 years old (mean 40.5, SD 11.5), 39 % were females and 77 % born outside Sweden. Routes of transmission were heterosexual transmission 63 %, male to male sex 20 %, intravenous drug use 5 %, blood product/transfusion 2 %, and unknown 9 %. All scale items had <3 % missing values. The data was feasible for factor analysis (KMO = 0.92) and a four-factor solution was chosen, based on level of explained common variance (58.64 %) and interpretability of factor structure. The factors were interpreted as; personal consequences, structural barriers, social and economic security, and confidentiality. Ratings on the minimum level (suggested barrier not important) were common, resulting in substantial floor effects on the scales. The scales were internally consistent (Cronbach's α 0.78-0.91). CONCLUSIONS This study gives preliminary evidence of the scale being feasible, reliable and valid to identify different types of barriers to HIV testing.

Abstract
Background In Malawi, outpatients who have presumptive tuberculosis (TB), i.e. fever, night sweats, weight loss and/or any-duration cough (HIV-infected) or cough of at least 2 weeks (HIV-uninfected), are registered in chronic cough registers. They should receive a diagnostic work-up with first-step provider-initiated HIV testing and sputum testing which includes XpertMTB/RIF, following a national algorithm introduced in 2012. Methods An operational study, in which we prospectively studied 6-month outcomes of adult outpatients who were registered in chronic cough registers in Zomba Central Hospital and Matawale peri-urban Health Center, between February and September 2013. We recorded implementation of the diagnostic protocol and outcomes at 6 months from registration. Results Of 348 patients enrolled, 165(47%) were male, median age was 40 years, 72(21%) had previous TB. At registration 154(44%) were known HIV-positive, 34(10%) HIV-negative (26 unconfirmed) and 160(46%) had unknown HIV status; 104(56%) patients with unknown/unconfirmed HIV status underwent HIV testing. At 6 months 191(55%) were HIV-positive, 87(25%) HIV-negative (26 unconfirmed) and 70(20%) still had unknown HIV status. Higher age and registration in Matawale were independently associated with remaining unknown HIV status after 6 months. 62% of patients had sputum tested, including XpertMTB/RIF, according to the algorithm. TB was diagnosed in 54(15%) patients. This was based on XpertMTB/RIF results in 8(15%) diagnosed cases. In 26(48%) TB was diagnosed on clinical grounds. Coverage of ART in HIV-positive patients was 89%. At 6 months, 236(68%) were asymptomatic, 48(14%) symptomatic, 25(7%) had been lost-to-follow-up and 39(11%) had died. Mortality among those HIV-positive, HIV-negative and with unknown HIV-status was 15%, 2% and 10%, respectively. Male gender, being HIV-positive-not-on-ART and not receiving antibiotics were independent risk factors for mortality. Conclusion HIV prevalence among patients with presumptive TB was high (55%). One quarter was not HIV tested and mortality in this group was substantial (10%). The impact of XpertMTB/RIF on TB diagnosis was limited.

Abstract
Alcohol-serving venues in South Africa are sites for high-risk behaviours that may lead to HIV transmission. Prevention and treatment interventions are sorely needed in these settings, but HIV-related stigma may limit their effectiveness. This study explored expressions of stigma among alcohol-serving venue patrons in Cape Town and examined the potential impact of stigma on HIV disclosure, testing and treatment-seeking behaviours. A total of 92 in-depth interviews with male and female, black and coloured patrons were conducted. Transcripts were analysed via memo-writing and diagramming techniques. Many participants mentioned knowing other patrons living with HIV/AIDS (PLWH), and this visibility of HIV impacted expressions of HIV-related stigma. Participants discussed four forms of HIV-related stigma in the venues: fearing PLWH, fearing HIV acquisition, blaming others for spreading HIV and isolating PLWH. HIV visibility and expressions of HIV-related stigma, particularly fear of isolation, influenced participants' willingness to disclose their status. HIV-related stigma in the venues also appeared to indirectly influence testing and treatment-seeking behaviour outside the venue. Results suggest that efforts to change norms and reduce expressions of HIV-related stigma in alcohol-serving venues are necessary to successfully deliver tailored HIV prevention interventions and increase uptake of HIV testing and care in this important social setting.

Abstract
Background Opt-out HIV testing is a novel concept in Australia. In the opt-out approach, health care providers (HCPs) routinely test patients for HIV unless they explicitly decline or defer. Opt-out HIV testing is only performed with the patients’ consent, but pre-test counselling is abbreviated. Australian national testing guidelines do not currently recommend opt-out HIV testing for the general population. Non-traditional approaches to HIV testing (such as opt-out) could identify HIV infections and facilitate earlier treatment, which is particularly important now that HIV is a chronic, manageable disease. Our aim was to explore HCPs’ attitudes toward opt-out HIV testing in an Australian context, to further understanding of its acceptability and feasibility. Methods In this qualitative study, we used purposeful sampling to recruit HCPs who were likely to have experience with HIV testing in Western Australia. We interviewed them using a semi-structured guide and used content analysis as per Graneheim to code the data. Codes were then merged into subcategories and finally themes that unified the underlying concepts. We refined these themes through discussion among the research team. Results Twenty four HCPs participated. Eleven participants had a questioning attitude toward opt-out HIV testing, while eleven favoured the approach. The remaining two participants had more nuanced perspectives that incorporated some characteristics of the questioning and favouring attitudes. Participants’ views about opt-out HIV testing largely fell into two contrasting themes: normalisation and routinisation versus exceptionalism; and a need for proof versus openness to new approaches. Conclusion Most HCPs in this study had dichotomous attitudes toward opt-out HIV testing, reflecting contrasting analytical styles. While some HCPs viewed it favourably, with the perceived benefits outweighing the perceived costs, others preferred to have evidence of efficacy and cost-effectiveness.

A qualitative study comparing clients' experiences of accessing HIV testing at public sector primary health care facilities or non-governmental mobile services in Cape Town, South Africa. BMC Public Health 2015; 15:845. [PMID: 26329262 PMCID: PMC4557635 DOI: 10.1186/s12889-015-2173-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2015] [Accepted: 08/21/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The South African government is striving for universal access to HIV counselling and testing (HCT), a fundamental component of HIV care and prevention. In the Cape Town district, Western Cape Province of South Africa, HCT is provided free of charge at publically funded primary health care (PHC) facilities and through non-governmental organizations (NGOs). This study investigated the availability and accessibility of HCT services; comparing health seeking behaviour and client experiences of HCT across public PHC facilities (fixed sites) and NGO mobile services. METHODS This qualitative study used semi-structured interviews. Systematic sampling was used to select 16 participants who accessed HCT in either a PHC facility (8) or a NGO mobile service (8). Interviews, conducted between March and June 2011, were digitally recorded, transcribed and where required, translated into English. Constant comparative and thematic analysis was used to identify common and divergent responses and themes in relation to the key questions (reasons for testing, choice of service provider and experience of HCT). RESULTS The sample consisted of 12 females and 4 males with an age range of 19-60 years (median age 28 years). Motivations for accessing health facilities and NGO services were similar; opportunity to test, being affected by HIV and a perceived personal risk for contracting HIV. Participants chose a particular service provider based on accessibility, familiarity with and acceptability of that service. Experiences of both services were largely positive, though instances of poor staff attitude and long waiting times were reported at PHC facilities. Those attending NGO services reported shorter waiting times and overall positive testing experiences. Concerns about lack of adequate privacy and associated stigma were expressed about both services. CONCLUSIONS Realised access to HCT is dependent on availability and acceptability of HCT services. Those who utilised either a NGO mobile service or a public PHC facility perceived both service types as available and acceptable. Mobile NGO services provided an accessible opportunity for those who would otherwise not have tested at that time. Policy makers should consider the perceptions and experiences of those accessing HCT services when increasing access to HCT.

Uptake, Accuracy, Safety, and Linkage into Care over Two Years of Promoting Annual Self-Testing for HIV in Blantyre, Malawi: A Community-Based Prospective Study. PLoS Med 2015; 12:e1001873.

Abstract
BACKGROUND Home-based HIV testing and counselling (HTC) achieves high uptake, but is difficult and expensive to implement and sustain. We investigated a novel alternative based on HIV self-testing (HIVST). The aim was to evaluate the uptake of testing, accuracy, linkage into care, and health outcomes when highly convenient and flexible but supported access to HIVST kits was provided to a well-defined and closely monitored population. METHODS AND FINDINGS Following enumeration of 14 neighbourhoods in urban Blantyre, Malawi, trained resident volunteer-counsellors offered oral HIVST kits (OraQuick ADVANCE Rapid HIV-1/2 Antibody Test) to adult (≥16 y old) residents (n = 16,660) and reported community events, with all deaths investigated by verbal autopsy. Written and demonstrated instructions, pre- and post-test counselling, and facilitated HIV care assessment were provided, with a request to return kits and a self-completed questionnaire. Accuracy, residency, and a study-imposed requirement to limit HIVST to one test per year were monitored by home visits in a systematic quality assurance (QA) sample. Overall, 14,004 (crude uptake 83.8%, revised to 76.5% to account for population turnover) residents self-tested during months 1-12, with adolescents (16-19 y) most likely to test. 10,614/14,004 (75.8%) participants shared results with volunteer-counsellors. Of 1,257 (11.8%) HIV-positive participants, 26.0% were already on antiretroviral therapy, and 524 (linkage 56.3%) newly accessed care with a median CD4 count of 250 cells/μl (interquartile range 159-426). HIVST uptake in months 13-24 was more rapid (70.9% uptake by 6 mo), with fewer (7.3%, 95% CI 6.8%-7.8%) positive participants. Being "forced to test", usually by a main partner, was reported by 2.9% (95% CI 2.6%-3.2%) of 10,017 questionnaire respondents in months 1-12, but satisfaction with HIVST (94.4%) remained high. No HIVST-related partner violence or suicides were reported. HIVST and repeat HTC results agreed in 1,639/1,649 systematically selected (1 in 20) QA participants (99.4%), giving a sensitivity of 93.6% (95% CI 88.2%-97.0%) and a specificity of 99.9% (95% CI 99.6%-100%). Key limitations included use of aggregate data to report uptake of HIVST and being unable to adjust for population turnover. CONCLUSIONS Community-based HIVST achieved high coverage in two successive years and was safe, accurate, and acceptable. Proactive HIVST strategies, supported and monitored by communities, could substantially complement existing approaches to providing early HIV diagnosis and periodic repeat testing to adolescents and adults in high-HIV settings.

Protocol for a systematic review: understanding the motivations and barriers to uptake and use of female-initiated, primary biomedical HIV prevention technologies in sub-Saharan Africa. Syst Rev 2015; 4:111. [PMID: 26286506 PMCID: PMC4545706 DOI: 10.1186/s13643-015-0096-1] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2015] [Accepted: 07/30/2015] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Women in sub-Saharan Africa are disproportionately affected by high rates of HIV, yet relatively few products exist for female-initiated HIV prevention. New antiretroviral (ARV)-based prevention options could present opportunities for women to expand their HIV prevention choices; however, acceptability and adherence play a key role in the effectiveness of these products and implementation is still in early stages. To better understand which HIV prevention options might best serve women in sub-Saharan Africa, how and why, this review will explore qualitative evidence from clinical trials and implementation studies alike using a meta-ethnographic approach to synthesise data and interpret results. METHODS/DESIGN This systematic review will use a meta-ethnographic approach to analyse qualitative data extracted from multiple studies featuring actual use of female-initiated technologies for HIV prevention. The search strategy will be applied in seven databases and papers will be selected using strict inclusion and exclusion criteria. The review will closely follow the guidance set forth by preferred reporting items for systematic reviews and meta-analyses (PRISMA) and Centre for Reviews Dissemination (CRD) where the guidance applies to qualitative data. Two reviewers will review all papers during the paper selection phase, with consultation from a third reviewer to confirm consensus. All papers included in the review will be read and analysed by two reviewers. The final analysis will be conducted by three primary reviewers with additional input from all other authors. DISCUSSION With new HIV prevention technologies currently in early implementation phases and still more on the horizon, there is much to learn about how best these products may be delivered. A review such as this could help to inform the real-world implementation of the next wave of new HIV prevention technologies such as ARV-based oral pre-exposure prophylaxis (PrEP).

Abstract
Background Voluntary HIV counseling and testing (VCT) is a key strategy towards HIV prevention yet, the uptake of VCT services among young people remains low. This study determined the factors that influence the uptake of VCT among secondary school students in Arusha City, Tanzania. Methods A cross sectional study using quantitative methods was conducted. A multi-stage sampling method was applied to randomly select the secondary schools. Stratification, random and systematic sampling techniques were used to identify the study participants. Interviews were conducted using structured questionnaires. Data analysis was done using statistical package for social sciences version 16. Analytical statistics were done using odds ratio to measure strength of association between VCT uptake and independent variables. Association with p-value < 0.05 was considered significant. Binary logistic regression was used to identify predictors of VCT uptake. Results Of 400 study participants, 50.5% were male and 49.5% were female. 93.5% of the respondents were aware of the VCT services, 79.1% had high knowledge on VCT services and 75.9% had positive attitude towards VCT services. On VCT uptake, only 29.3% had ever tested. VCT uptake was found to be significantly predicted by age (p = 0.003), sex (p < 0.001), religion (p < 0.001), exposure to VCT information from a VCT centre (p < 0.001) and type of school ownership (p < 0.013). Conclusion Despite high knowledge on VCT services, the uptake of VCT among secondary school students was found to be low. The uptake of VCT was mainly found to be influenced by fear of HIV test results, knowledge and attitude on VCT services, age, education, engagement in sexual relationships, stigma and distance to the VCT centre. Integration of youth friendly VCT services in secondary schools would increase VCT uptake among secondary school students. Support and care received after knowing the test results should be clearly communicated as it helps motivate more young people towards VCT uptake and reduce stigma among them.

Abstract
Background HIV counselling and testing (HCT) and knowledge about HIV have been key strategies utilised in the prevention and control of HIV/AIDS worldwide. HIV knowledge and uptake of HCT services in sub-Saharan Africa are still low. This study was conducted to determine factors associated with HCT and HIV/AIDS knowledge levels among a commuter population in Johannesburg, South Africa. Objective To identify the factors associated with HCT uptake among the commuter population. Design A simple random sampling method was used to select participants in a venue-based intercept survey at a taxi rank in the Johannesburg Central Business District. Data were collected using an electronic questionnaire. Logistic regression analysis assessed factors associated with HIV testing stratified by gender. Results 1,146 respondents were interviewed, the maority (n=579, 50.5%) were females and (n=780, 68.1%) were over 25 years of age. Overall HCT knowledge was high (n=951, 83%) with more females utilising HCT facilities. There was a significant difference in HIV testing for respondents living closer to and further away from health facilities. Slightly more than half of the respondents indicated stigma as one of the barriers for testing (n=594, 52%, p-value=0.001). For males, living with a partner (aOR: 1.68, 95% CI: 1.02–2.78, p-value: 0.041) and possessing a post-primary education were positively associated with testing (aOR: 2.00, 95% CI: 1.15–3.47, p-value: 0.014), whereas stigma and discrimination reduced the likelihood of testing (aOR: 0.40, 95% CI: 0.31–0.62, p-value: <0.001). For females, having one sexual partner (aOR: 2.65, 95% CI: 1.19–5.90, p-value: 0.017) and a low perceived benefit for HIV testing (aOR: 0.54, 95% CI: 0.30–0.96, p-value: 0.035) were associated with HIV testing. Conclusion The overall HIV/AIDS knowledge was generally high. Gender-specific health education and HIV intervention programmes are needed for improved access to HCT services. One favourable intervention would be the use of home-based HCT programmes.

Assessment of policy and access to HIV prevention, care, and treatment services for men who have sex with men and for sex workers in Burkina Faso and Togo. J Acquir Immune Defic Syndr 2015; 68 Suppl 2:S189-97.

Abstract
BACKGROUND In Burkina Faso and Togo, key populations of men who have sex with men (MSM) and sex workers (SW) have a disproportionately higher HIV prevalence. This study analyzed the 2 countries' policies impacting MSM and SW; to what extent the policies and programs have been implemented; and the role of the enabling environment, country leadership, and donor support. METHODS The Health Policy Project's Policy Assessment and Advocacy Decision Model methodology was used to analyze policy and program documents related to key populations, conduct key informant interviews, and hold stakeholder meetings to validate the findings. RESULTS Several policy barriers restrict MSM/SW from accessing services. Laws criminalizing MSM/SW, particularly anti-solicitation laws, result in harassment and arrests of even nonsoliciting MSM/SW. Policy gaps exist, including few MSM/SW-supportive policies and HIV prevention measures, e.g., lubricant not included in the essential medicines list. The needs of key populations are generally not met due to policy gaps around MSM/SW participation in decision-making and funding allocation for MSM/SW-specific programming. Misaligned policies, eg, contradictory informed consent laws and protocols, and uneven policy implementation, such as stockouts of sexually transmitted infection kits, HIV testing materials, and antiretrovirals, undermine evidence-based policies. Even in the presence of a supportive donor and political community, public stigma and discrimination (S&D) create a hostile enabling environment. CONCLUSIONS Policies are needed to address S&D, particularly health care provider and law enforcement training, and to authorize, fund, guide, and monitor services for key populations. MSM/SW participation and development of operational guidelines can improve policy implementation and service uptake.

BMC Public Health 2015; 15:388.

Abstract
Background The proposal by the South African Health Ministry to implement HIV testing and counselling (HTC) at schools in 2011 generated debates about the appropriateness of such testing. However, the debate has been between the Ministries of Education and Health, with little considerations of the students. The main aim of the study was to assess the students’ opinions and uptake of HIV testing and counselling in general, and the acceptability of the provision of HIV testing and counselling in schools. The study also determined the association between socio-demographic characteristics, sexual behaviour, and HIV testing behaviour of the students. Methods A survey was conducted among grade 10–12 high school students in North West and Gauteng provinces, South Africa. Seventeen high schools (nine rural and eight urban) were randomly selected for the administration of a researcher-assisted, self-administered, semi-structured questionnaire. Results A total of 2970 students aged 14–27 years participated in the study; 1632 (55%) were girls, 1810 (61%) ever had sex, and 1271 (49.8%) had more than one sex partner. The mean age of first sexual activity was 15.6. Half (n = 1494, 50.1%) had been tested for HIV. Having multiple sexual partners, age, and gender were significantly associated with increased odds of having had a HIV test. Fear, being un-informed about HTC, and low HIV risk perceptions were the reasons for not getting tested. The acceptability of HTC at school was high (n = 2282, 76.9%) and 2129 (71.8%) were willing to be tested at school. Appropriateness, privacy, and secrecy were the main arguments for and against HTC at school. One-third (n = 860, 29%) had intentions to disclose their HIV status to students versus 1258 (42.5%) for teachers. Stigma, discrimination and secrecy were the primary reasons students did not intend to disclose. Conclusions A high acceptability of HTC and willingness to be tested at school suggest that HIV prevention programs tailored to youth have a high potential of success given the readiness of students to uptake HTC. Bringing HIV testing to the school setting will increase the uptake of HTC among youth and contribute towards efforts to scale up HTC in South Africa.

Abstract
BACKGROUND Home HIV counselling and testing (HTC) achieves high coverage of testing and linkage to care compared with existing facility-based approaches, particularly among asymptomatic individuals. In a modelling analysis we aimed to assess the effect on population-level health and cost-effectiveness of a community-based package of home HTC in KwaZulu-Natal, South Africa. METHODS We parameterised an individual-based model with data from home HTC and linkage field studies that achieved high coverage (91%) and linkage to antiretroviral therapy (80%) in rural KwaZulu-Natal, South Africa. Costs were derived from a linked microcosting study. The model simulated 10,000 individuals over 10 years and incremental cost-effectiveness ratios were calculated for the intervention relative to the existing status quo of facility-based testing, with costs discounted at 3% annually. FINDINGS The model predicted implementation of home HTC in addition to current practice to decrease HIV-associated morbidity by 10–22% and HIV infections by 9–48% with increasing CD4 cell count thresholds for antiretroviral therapy initiation. Incremental programme costs were US$2·7 million to $4·4 million higher in the intervention scenarios than at baseline, and costs increased with higher CD4 cell count thresholds for antiretroviral therapy initiation; antiretroviral therapy accounted for 48–87% of total costs. Incremental cost-effectiveness ratios per disability-adjusted life-year averted were $1340 at an antiretroviral therapy threshold of CD4 count lower than 200 cells per μL, $1090 at lower than 350 cells per μL, $1150 at lower than 500 cells per μL, and $1360 at universal access to antiretroviral therapy. INTERPRETATION Community-based HTC with enhanced linkage to care can result in increased HIV testing coverage and treatment uptake, decreasing the population burden of HIV-associated morbidity and mortality. The incremental cost-effectiveness ratios are less than 20% of South Africa's gross domestic product per person, and are therefore classed as very cost effective. Home HTC can be a viable means to achieve UNAIDS' ambitious new targets for HIV treatment coverage. FUNDING National Institutes of Health, Bill & Melinda Gates Foundation, Wellcome Trust.

Abstract
This study examined the predictors of intention to use HIV counseling and testing (HCT) services among those who had never used HCT services in a sample of 2,536 Thai youth in Bangkok (ages 15-24). Web-based questionnaires included assessments of HIV knowledge, HIV testing attitude, AIDS stigma, and youth-friendly HCT (YFHCT) service expectation. More than 80% of the sexually experienced youth had never used HCT services but among this group 74.06% reported having intentions to do so. The significant predictors consisted of favorable expectations of YFHCT services (p < .001), positive attitude toward HIV testing (p < .005), perceived high risk for HIV infection (p < .01), having multiple sex partners while also using condoms consistently (p < .01), willingness to pay (p < .001), and being informed about HCT and knowing service locations (p < .001). Policy makers, as well as health promotion program developers and researchers can use these findings to increase intention and use of HCT services among at-risk youth.

Abstract
This short report identifies enablers and barriers to the uptake of provider-initiated testing and counselling for HIV (PITC) in Namibia and identifies key opportunities for strengthening this vital aspect of the national HIV response. We explored this through facility mapping, register reviews and qualitative methods including focus group discussions and in-depth interviews. Four health facilities (clinics and hospitals) in two regions were included in the study. We identified that PITC in Namibia was largely delivered by lay counsellors operating in designated rapid testing rooms located in health facilities and found a large number of missed opportunities for HIV testing through this model. Nurses did not see it as an integral part of their role, were not aware of HIV testing and counselling policy, felt inadequately trained and supported, and experienced staffing shortages. Institutional issues also acted as barriers to nurses performing or initiating discussions about PITC. Wider dissemination and implementation of policy, increasing privacy of consultation spaces and community sensitisation are simple measures that represent opportunities for strengthening this response and ensuring that symptomatic individuals who are unaware of their HIV status do not fall through the net.

Abstract
While men who have sex with men (MSM) in Africa are at high risk for HIV infection, few of those already infected know their status. Effectively promoting frequent HIV testing-of increasing importance with the expanding accessibility of antiretroviral treatment-requires an understanding of the testing practices in this population. To understand men's HIV testing practices, including their behavior, experiences, and perceptions, we conducted in-depth interviews with 81 black South African MSM (ages 20-39), purposively recruited from four townships. Many men in the sample had tested for HIV. While ever having tested seemed to facilitate repeat testing, men still expressed a high level of discomfort with testing. It was common to test after having engaged in risky behavior, thus increasing anxiety about testing that was already present. Fear that they might test HIV positive caused some men to avoid testing until they were clearly sick, and others to avoid testing completely. HIV testing may increase in this population if it becomes a routine practice, instead of being driven by anxiety-inducing incidents. Mobilization through social support might facilitate frequent testing while education about current treatment options is needed.

Abstract
The stigma attached to HIV is a major public health problem given its adverse impacts on HIV prevention and on the psychosocial wellbeing of persons with HIV. In this study, I apply a novel method to data from the Demographic and Health Surveys to identify persons with HIV who were aware of their seropositivity at the time of the survey. The pooled dataset includes 4,314 persons with HIV in Cameroon, Ethiopia, Gabon, Kenya, Lesotho, Malawi, Rwanda, Swaziland, Tanzania, Uganda, Zambia, and Zimbabwe. My findings indicate that nearly one-fifth of study participants provided survey responses consistent with internalization of stigmatizing beliefs. Furthermore, in multivariable regression models, striking socioeconomic gradients in internalized stigma were observed. A clear implication of my findings is that the adverse health and psychosocial impacts of HIV stigma are likely concentrated among those with the fewest socioeconomic resources for managing and resisting it.

Abstract
Background This study aimed to determine barriers to accessing human immunodeficiency virus (HIV) counseling and testing (HCT) services among a commuter population. Methods A cross-sectional, venue-based intercept survey was conducted. Participants were recruited during a 2-day community campaign at the Noord Street taxi rank in Johannesburg, South Africa. Data were collected using a self-administered questionnaire loaded onto an electronic data collection system and analyzed using Stata software. Factors contributing to barriers for HCT were modeled using multivariate logistic regression. Results A total of 1,146 (567 male and 579 female) individuals were interviewed; of these, 51.4% were females. The majority (59.5%) were aged 25–35 years. Significant factors were age group (15–19 years), marital status (married), educational level (high school), distance to the nearest clinic (>30 km), area of employment/residence (outside inner city), and number of sexual partners (more than one). Participants aged 15–19 years were more likely to report low-risk perception of HIV as a barrier to HCT (odds ratio [OR] 1.62; 95% confidence interval [CI] 1.01–2.59), the married were more likely to report low-risk perception of HIV as a barrier to HCT (OR 1.49; 95% CI 1.13–1.96), and those living outside the inner city were more likely to report lack of partner support as a potential barrier (OR 1.94; 95% CI 1.34–2.80), while those with a high school education were more likely to report poor health worker attitude as a potential barrier to HIV testing (OR 2.17; 95% CI 1.36–3.45). Conclusion Age, marital status, occupation, educational level, area of employment and residence, distance to the nearest clinic, and number of sexual partners were factors significantly associated with barriers to HIV testing in the study population. Future HIV intervention targeting this population need to be reinforced in order to enhance HIV testing while taking cognizance of these factors.

Abstract
In 2012, we interviewed a population-based sample of 285 young adult residents (age 18-35 years) of the city of Bo, Sierra Leone, about their attitudes toward and experience with voluntary testing and counseling (VCT) for HIV. In total, 33% of the participants (44% of women and 25% of men) reported having been tested for HIV at least once. More than 85% of those not previously tested indicated a willingness to be tested in the near future, but untested participants were nearly twice as likely as tested participants to report fears about family/partner rejection, job loss, and other potential consequences of testing. More than 90% of participants expressed a high desire for testing privacy, and the majority reported a preference for VCT at a facility far from home where no one would know them. Social barriers to HIV testing remain a challenge for HIV prevention in Sierra Leone.

Abstract
BACKGROUND Both population- and individual-level benefits of antiretroviral therapy (ART) for human immunodeficiency virus (HIV) are contingent on early diagnosis and initiation of therapy. We estimated trends in disease status at presentation to care and at ART initiation in sub-Saharan Africa. METHODS We searched PubMed for studies published January 2002-December 2013 that reported CD4 cell count at presentation or ART initiation among adults in sub-Saharan Africa. We abstracted study sample size, year(s), and mean CD4 count. A random-effects meta-regression model was used to obtain pooled estimates during each year of the observation period. RESULTS We identified 56 articles reporting CD4 count at presentation (N = 295 455) and 71 articles reporting CD4 count at ART initiation (N = 549 702). The mean estimated CD4 count in 2002 was 251 cells/µL at presentation and 152 cells/µL at ART initiation. During 2002-2013, neither CD4 count at presentation (β = 5.8 cells/year; 95% confidence interval [CI], -10.7 to 22.4 cells/year), nor CD4 count at ART initiation (β = -1.1 cells/year; 95% CI, -8.4 to 6.2 cells/year) increased significantly. Excluding studies of opportunistic infections or prevention of mother-to-child transmission did not alter our findings. Among studies conducted in South Africa (N = 14), CD4 count at presentation increased by 39.9 cells/year (95% CI, 9.2-70.2 cells/year; P = .02), but CD4 count at ART initiation did not change. CONCLUSIONS CD4 counts at presentation to care and at ART initiation in sub-Saharan Africa have not increased over the past decade. Barriers to presentation, diagnosis, and linkage to HIV care remain major challenges that require attention to optimize population-level benefits of ART.

Abstract
OBJECTIVES To examine changes between 2006 and 2011 in the proportion of HIV-positive patients newly enrolled in HIV care with advanced disease and the median CD4 cell count at enrollment; and identify patient, facility, and contextual-level factors associated with late enrollment in care in 2011. DESIGN Cross-sectional over time. METHODS For time-trends analyses, routinely collected patient-level data (307 110 adults newly enrolled in 138 HIV clinical care facilities) in Kenya, Mozambique, Rwanda and Tanzania; and for analyses of correlates, patient-level data (46 201 in 195 facilities), and facility and population-level survey data were used. Late enrollment was defined as CD4 cell count 350 cells/μl or less and/or WHO clinical stage 3/4. RESULTS Late enrollment declined from 69.9 to 57.2% (P < 0.0001); median CD4 cell count increased from 242 to 292 cells/μl (Ptrend < 0.0001). In 2011, risk of late enrollment was significantly higher for men and nonpregnant women vs. pregnant women; patients aged above 25 vs. 15-25 years; nonmarried vs. married; and those entering from sites other than prevention of mother-to-child transmission. More extensive HIV testing coverage in the region of a facility was significantly associated with lower risk of late enrollment. CONCLUSIONS Despite improvement, in 2011, 57% of patients entered HIV care who were already antiretroviral therapy-eligible. The lower risk of late enrollment among those referred from prevention of mother-to-child transmission and in regions where HIV testing coverage was higher suggests that innovative approaches to rapidly increase testing uptake among people living with HIV prior to the development of symptoms have the potential to reduce late enrollment in care.

Abstract
Point-of-care (POC) testing in communities, home settings and primary healthcare centers plays an important role in cutting delays in HIV diagnosis and in the uptake of voluntary testing and counseling. Qualitative research methods have important potential to overcome the current challenges in expanding HIV POC testing programs and strategies, by examining the diagnostic processes, complex inter-relationships and patterns involved in making POC diagnostics work in real-world settings. This article reviews existing qualitative studies on POC testing strategies and programs for HIV. Qualitative research on POC diagnostics around the uptake of POC tests, the actual diagnostic and testing processes involved, the influence of POC tests on clinical decision-making, communication of decisions and decisions exercised by patients are limited. Equally limited are studies that explore adaptation of POC programs to various socio-cultural contexts. More qualitative research is needed to inform test developers, funders and policymakers.

Abstract
Objective To determine factors associated with HIV status unawareness and assess HIV prevention knowledge and condom use among people living with HIV/AIDS (PLHIV) in Mozambique. Design Cross-sectional household-based nationally representative AIDS Indicator Survey. Methods Analyses focused on HIV-infected adults and were weighted for the complex sampling design. We identified PLHIV who had never been tested for HIV or received their test results prior to this survey. Logistic regression was used to assess factors associated with HIV status unawareness. Results Of persons with positive HIV test results (N = 1182), 61% (95% confidence interval [CI] 57–65%) were unaware of their serostatus. Men had twice the odds of being unaware of their serostatus compared with women [adjusted odds ratio (aOR) 2.05, CI 1.40–2.98]. PLHIV in the poorest wealth quintile were most likely to be unaware of their serostatus (aOR 3.15, CI 1.09–9.12) compared to those in the middle wealth quintile. Most PLHIV (83%, CI 79–87%) reported not using a condom during their last sexual intercourse, and PLHIV who reported not using a condom during their last sexual intercourse were more likely to be unaware of their serostatus (aOR 2.32, CI 1.57–3.43) than those who used a condom. Conclusions Knowledge of HIV-positive status is associated with more frequent condom use in Mozambique. However, most HIV-infected persons are unaware of their serostatus, with men and persons in the poorest wealth quintile being more likely to be unaware. These findings support calls for expanded HIV testing, especially among groups less likely to be aware of their HIV status and key populations at higher risk for infection.

Role of community-level factors across the treatment cascade: a critical review. J Acquir Immune Defic Syndr 2014; 66 Suppl 3:S311-8.

Abstract
Addressing community-level factors (CLFs) is integral to the ongoing effort to design multilevel, effective, and sustainable interventions to address each element of the HIV/AIDS treatment cascade. This review, the first critical review of this topic, identified 100 articles that (1) assessed CLFs in relation to the HIV/AIDS treatment cascade, (2) had been peer-reviewed, and (3) were based on studies conducted in low- or middle-income countries. Social support and social networks, cultural norms, gender norms, and stigma were the key CLFs associated with treatment and care. This extensive review found only 5 evaluations of interventions designed to affect CLFs, reflecting a major gap in the literature. All were communication interventions designed to create a more positive environment for HIV testing and access to treatment and care, thus pointing to some of the potential extraindividual effects of communication interventions. The qualitative data are rich and vital for understanding the context; yet, more quantitative analysis to provide evidence regarding the distribution of these factors is essential, as only 19 of the studies were quantitative. There is a pressing need to (1) collect community-level data, (2) validate social and gender norm scales, and (3) better use available data regarding social norms, gender norms, and other CLFs. These data could be aggregated at the cluster, neighborhood, or community levels and incorporated into multilevel analysis to help clarify the pathways to enhanced outcomes across the treatment cascade and thereby mitigate HIV sequelae.

Abstract
Progression through the HIV continuum of care, from HIV testing to lifelong retention in antiretroviral therapy (ART) care and treatment programs, is critical to the success of HIV treatment and prevention efforts. However, significant losses occur at each stage of the continuum and little is known about contextual factors contributing to disengagement at these stages. This study sought to explore multi-level barriers and facilitators influencing entry into and engagement in the continuum of care in Iringa, Tanzania. We used a mixed-methods study design including facility-based assessments and interviews with providers and clients of HIV testing and treatment services; interviews, focus group discussions and observations with community-based providers and clients of HIV care and support services; and longitudinal interviews with men and women living with HIV to understand their trajectories in care. Data were analyzed using narrative analysis to identify key themes across levels and stages in the continuum of care. Participants identified multiple compounding barriers to progression through the continuum of care at the individual, facility, community and structural levels. Key barriers included the reluctance to engage in HIV services while healthy, rigid clinic policies, disrespectful treatment from service providers, stock-outs of supplies, stigma and discrimination, alternate healing systems, distance to health facilities and poverty. Social support from family, friends or support groups, home-based care providers, income generating opportunities and community mobilization activities facilitated engagement throughout the HIV continuum. Findings highlight the complex, multi-dimensional dynamics that individuals experience throughout the continuum of care and underscore the importance of a holistic and multi-level perspective to understand this process. Addressing barriers at each level is important to promoting increased engagement throughout the continuum.

HIV testing preferences in Tanzania: a qualitative exploration of the importance of confidentiality, accessibility, and quality of service. BMC Public Health 2014; 14:838.

Abstract
Background HIV counseling and testing (HCT), an effective preventive strategy and an entry point for care, remains under-utilized in Tanzania. Limited uptake of HCT, despite the widespread availability of varied testing options, suggests that existing options may not align well with population preferences for testing. Methods Between October and December 2011, we conducted an exploratory study in the Kilimanjaro Region to develop a conceptual framework for understanding which characteristics of HIV testing are associated with preferences for testing. Forty individuals (55% women, 53% never having tested) participated in in-depth interviews and focus groups to identify factors that influence whether and where people test for HIV. Results A variety of discrete characteristics of testing venues, test providers, and testing procedures (e.g. distance to testing, counselor experience, type of HIV test, and availability of antiretroviral therapy) mapped conceptually to three domains: confidentiality of testing and test results, quality of HCT, and accessibility and availability of ancillary services. We noted heterogeneous preferences and demonstrate that while some test characteristics overlap and reinforce across multiple domains, others demand clients to make trade-offs between domains. Conclusion Testing decisions appear to be influenced by an array of often inter-linked factors across multiple domains, including quality, confidentiality, and accessibility; perceptions of these factors varied greatly across participants and across available testing options. HCT interventions that jointly target barriers spanning the three domains have the potential to increase uptake of HIV testing and deserve further exploration.

Abstract
This study's objective was to describe awareness of, access to, belief in, and utilization of the healing tea Kikombe cha babu and other alternative treatments for HIV in Tanzania. Associations with HIV testing, treatment, and prevention behaviors are also explored. A survey with questions about alternative medicine was administered to a sample in Tanzania using a stratified, multistage random selection method. Adults were interviewed face-to-face. Items concerning alternative HIV treatments addressed awareness, access, beliefs, and treatment-seeking behaviors. Questions about HIV prevention and treatment were also asked. Results showed participants indicated a high awareness of alternative treatments available in Tanzania, with 95.3% of 2313 adults having heard of these treatments. Of those, 6.0% had actually sought the treatment, and 46.8% had an acquaintance seek it. However, 81.0% indicated these treatments were not easily accessible. There is a high level of belief in the ability of these alternative treatments to cure HIV, with 44.0% of people who had heard of these treatments indicating they believe such treatments can cure HIV. Additionally, many people indicated having these alternative treatments available would result in decreased condom use (15.6%), no need to use condoms (94.9%), and no need to take antiretroviral therapy (81.7%). However, 57.4% indicated they would be more likely to get tested for HIV if alternative treatments were available. Belief in the ability of alternative treatments to cure HIV in Tanzania is high and should be further explored due to its implications for potentially sidelining HIV prevention and treatment initiatives.

Abstract
Background HIV is a major public health problem in the world, especially in sub-Saharan Africa. It often leads to loss of productive labour and disruption of existing social support system which results in deterioration of population health. This poses a great challenge to infected people in meeting their essential goods and services. This paper examines health and social support services provided by employers to HIV/AIDS infected employees in Tanzania. Methods This was a cross-sectional study, which employed qualitative and quantitative methods in data collection and analysis. Structured questionnaires and in-depth interviews were used to assess the health and social support services provision at employers and employees perspectives. The study participants were employees and employers from public and private organizations. Results A total of 181 employees and 23 employers from 23 workplaces aged between 18–68 years were involved. The results show that 23.8% (i.e., 20.4% males and 27.3% females) of the employees had at least one member of the family or close relatives living with HIV at the time of the study. Fifty six percent of the infected employees reported to have been receiving health or social support from their employers. Employees’ responses were consistent with those reported by their employers. A total of 12(52.2%) and 11(47.8%) employers reported to have been providing health and social supports respectively. Female employees (58.3%) from the private sector (60.0%) were more likely to receive supports than male employees (52.6%) and than those from the public sector (46.2%). The most common health and social support received by the employees were treatment, and nutritional support and reduction of workload, respectively. Conclusions HIV/AIDS infected employees named treatment and nutritional support, and soft loans and reduced workload respectively, as the most important health and social supports they needed from their employers. This study provides baseline information for further studies on provision of health and social support services by employers to HIV/AIDS infected employees in the context of a developing economy like Tanzania.

Barriers to provider-initiated testing and counselling for children in a high HIV prevalence setting: a mixed methods study. PLoS Med 2014; 11:e1001649.

Abstract
BACKGROUND There is a substantial burden of HIV infection among older children in sub-Saharan Africa, the majority of whom are diagnosed after presentation with advanced disease. We investigated the provision and uptake of provider-initiated HIV testing and counselling (PITC) among children in primary health care facilities, and explored health care worker (HCW) perspectives on providing HIV testing to children. METHODS AND FINDINGS Children aged 6 to 15 y attending six primary care clinics in Harare, Zimbabwe, were offered PITC, with guardian consent and child assent. The reasons why testing did not occur in eligible children were recorded, and factors associated with HCWs offering and children/guardians refusing HIV testing were investigated using multivariable logistic regression. Semi-structured interviews were conducted with clinic nurses and counsellors to explore these factors. Among 2,831 eligible children, 2,151 (76%) were offered PITC, of whom 1,534 (54.2%) consented to HIV testing. The main reasons HCWs gave for not offering PITC were the perceived unsuitability of the accompanying guardian to provide consent for HIV testing on behalf of the child and lack of availability of staff or HIV testing kits. Children who were asymptomatic, older, or attending with a male or a younger guardian had significantly lower odds of being offered HIV testing. Male guardians were less likely to consent to their child being tested. 82 (5.3%) children tested HIV-positive, with 95% linking to care. Of the 940 guardians who tested with the child, 186 (19.8%) were HIV-positive. CONCLUSIONS The HIV prevalence among children tested was high, highlighting the need for PITC. For PITC to be successfully implemented, clear legislation about consent and guardianship needs to be developed, and structural issues addressed. HCWs require training on counselling children and guardians, particularly male guardians, who are less likely to engage with health care services. Increased awareness of the risk of HIV infection in asymptomatic older children is needed.

Impact of HIV-related stigma on treatment adherence: systematic review and meta-synthesis. J Int AIDS Soc 2013; 16:18640.

Abstract
Introduction Adherence to HIV antiretroviral therapy (ART) is a critical determinant of HIV-1 RNA viral suppression and health outcomes. It is generally accepted that HIV-related stigma is correlated with factors that may undermine ART adherence, but its relationship with ART adherence itself is not well established. We therefore undertook this review to systematically assess the relationship between HIV-related stigma and ART adherence. Methods We searched nine electronic databases for published and unpublished literature, with no language restrictions. First we screened the titles and abstracts for studies that potentially contained data on ART adherence. Then we reviewed the full text of these studies to identify articles that reported data on the relationship between ART adherence and either HIV-related stigma or serostatus disclosure. We used the method of meta-synthesis to summarize the findings from the qualitative studies. Results Our search protocol yielded 14,854 initial records. After eliminating duplicates and screening the titles and abstracts, we retrieved the full text of 960 journal articles, dissertations and unpublished conference abstracts for review. We included 75 studies conducted among 26,715 HIV-positive persons living in 32 countries worldwide, with less representation of work from Eastern Europe and Central Asia. Among the 34 qualitative studies, our meta-synthesis identified five distinct third-order labels through an inductive process that we categorized as themes and organized in a conceptual model spanning intrapersonal, interpersonal and structural levels. HIV-related stigma undermined ART adherence by compromising general psychological processes, such as adaptive coping and social support. We also identified psychological processes specific to HIV-positive persons driven by predominant stigmatizing attitudes and which undermined adherence, such as internalized stigma and concealment. Adaptive coping and social support were critical determinants of participants’ ability to overcome the structural and economic barriers associated with poverty in order to successfully adhere to ART. Among the 41 quantitative studies, 24 of 33 cross-sectional studies (71%) reported a positive finding between HIV stigma and ART non-adherence, while 6 of 7 longitudinal studies (86%) reported a null finding (Pearson's χ2=7.7; p=0.005). Conclusions We found that HIV-related stigma compromised participants’ abilities to successfully adhere to ART. Interventions to reduce stigma should target multiple levels of influence (intrapersonal, interpersonal and structural) in order to have maximum effectiveness on improving ART adherence.

Abstract
Mobile unit (MU) HIV testing is an alternative method of providing healthcare access. We compared demographic and behavioural characteristics, HIV testing history and HIV prevalence between participants seeking testing at a MU vs. fixed clinic (FC) in Lima, Peru. Our analysis included men and transgender women (TW) in Lima aged ≥ 18 years old seeking HIV testing at their first visit to a community-based MU or FC from October 2007 to November 2009. HIV testing history, HIV serostatus and behavioural characteristics were analysed. A large percentage of MU attendees self-identified as transgender (13%) or heterosexual (41%). MU attendees were more likely to engage in transactional sex (24% MU vs. 10% FC, p < 0.001), use alcohol/drugs during their last sexual encounter (24% MU vs. 20% FC, p < 0.01) and/or be a first-time HIV tester (48% MU vs. 41% FC, p < 0.001). MU HIV prevalence was 9% overall and 5% among first-time testers (49% in TW and 11% in men who have sex with men [MSM] first-time testers). MU testing reached large numbers of at-risk (MSM/TW) populations engaged in unsafe sexual behaviours, making MU outreach a worthy complement to FC testing. Investigation into whether MU attendees would otherwise access HIV testing is warranted to determine the impact of MU testing.

Abstract
Central Asia is experiencing one of the fastest growing HIV epidemics in the world, with some areas' infection rates doubling yearly since 2000. This study examines the impact of multilevel stigma (individual, family, and community) on uptake of HIV testing and receipt of HIV testing results among women in Central Asia. The sample consists of 38,884 ever-married, Central Asian women between the ages of 15 and 49. Using multilevel modeling (MLM), HIV stigma variables at the individual, family, and community levels were used to assess the significance of differences in HIV testing and receipt of HIV test results among participants while adjusting for possible confounding factors, such as age, wealth, and education. MLM results indicate that HIV stigma is significantly associated with decreased HIV testing uptake at the individual, family, and community levels and with a decrease in receipt at the community level. A one standard deviation increase in individual, family, and community level composite stigma score was associated with a respective 49 %, 59 %, and 94 % (p < 0.001) decrease in the odds of having been tested for HIV. A one standard deviation increase in community composite stigma score was associated with a 99 % (p < 0.001) decrease in the odds of test receipt. HIV stigma operates on the individual, family, and community levels to hinder HIV testing uptake and at the community level to hinder receipt. These findings have important interventions implications to improve uptake of HIV testing and receipt of HIV test results.

Abstract
Program implementers and qualitative researchers have described how increasing availability of HIV antiretroviral therapy (ART) is associated with improvements in psychosocial health and internalized stigma. To determine whether, and through what channels, ART reduces internalized stigma, we analyzed data from 262 HIV-infected, treatment-naïve persons in rural Uganda followed from ART initiation over a median of 3.4 years. We fitted Poisson regression models with cluster-correlated robust estimates of variance, specifying internalized stigma as the dependent variable, adjusting for time on treatment as well as socio-demographic, clinical, and psychosocial variables. Over time on treatment, internalized stigma declined steadily, with the largest decline observed during the first 2 years of treatment. This trend remained statistically significant after multivariable adjustment (χ(2) = 28.3; P = 0.03), and appeared to be driven by ART-induced improvements in HIV symptom burden, physical and psychological wellbeing, and depression symptom severity.

Abstract
Background Stigma is a barrier to HIV prevention and treatment. There is a limited understanding of the types of stigma facing people living with HIV (PLHIV) on antiretroviral therapy (ART). We describe the stigma trajectories of PLHIV over a 5-year period from the time they started ART. Methods Longitudinal qualitative in-depth interviews were conducted with 41 members of The AIDS Support Organisation (TASO) from 2005 to 2008 in Jinja, Uganda, who were part of a pragmatic cluster-randomised trial comparing two different modes of ART delivery (facility and home). Participants were stratified by gender, ART delivery arm and HIV stage (early or advanced) and interviewed at enrolment on to ART and then after 3, 6, 18 and 30 months. Interviews focused on stigma and ART experiences. In 2011, follow-up interviews were conducted with 24 of the participants who could be traced. Transcribed texts were translated, coded and analyzed thematically. Results Stigma was reported to be very high prior to starting ART, explained by visible signs of long-term illnesses and experiences of discrimination and abuse. Early coping strategies included: withdrawal from public life, leaving work due to ill health and moving in with relatives. Starting ART led to a steady decline in stigma and allowed the participants to take control of their illness and manage their social lives. Better health led to resumption of work and having sex but led to reduced disclosure to employers, colleagues and new sexual partners. Some participants mentioned sero-sorting in order to avoid questions around HIV sero-status. A rise in stigma levels during the 18 and 30 month interviews may be correlated with decreased disclosure. By 2011, ART-related stigma was even more pronounced particularly among those who had started new sexual relationships, gained employment and those who had bodily signs from ART side-effects. Conclusion This study has shown that while ART comes with health benefits which help individuals to get rid of previously stigmatising visible signs, an increase in stigma may be noticed after about five years on ART, leading to reduced disclosure. ART adherence counselling should reflect changing causes and manifestations of stigma over time.

Abstract
The purpose of this study was to examine the results of implementing a rapid counselor-based HIV testing program in community pharmacies. A prospective cross-sectional study was conducted on a convenience sample of clients at five community pharmacies in New York City (NYC). In 294 days of pharmacy testing, 2805 clients were eligible to receive testing, and 2030 individuals agreed to test. The average age was 33±15 years, 41% were male, 59% were Hispanic, 77% had been previously tested for HIV, and 34% were uninsured. HIV incidence was 0.3%, median CD4 cell count was 622.0, and the average age of the newly diagnosed positives was 36.0±13.9 years. Participants were satisfied with a counselor-based rapid HIV testing program in community-based pharmacies.

Dye C. Making wider use of the world's most widely used vaccine: Bacille Calmette-Guerin revaccination reconsidered. J R Soc Interface 2013; 10:20130365. [PMID: 23904584 PMCID: PMC3757998 DOI: 10.1098/rsif.2013.0365] [Citation(s) in RCA: 67] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/24/2023] Open
Abstract
Approximately 100 million newborn children receive Bacille Calmette–Guérin (BCG) annually, because vaccination is consistently protective against childhood tuberculous meningitis and miliary TB. By contrast, BCG efficacy against pulmonary TB in children and adults is highly variable, ranging from 0% to 80%, though it tends to be higher in individuals who have no detectable prior exposure to mycobacterial infections, as judged by the absence of delayed-type hypersensitivity response (a negative tuberculin skin test, TST). The duration of protection against pulmonary TB is also variable, but lasts about 10 years on average. These observations raise the possibility that BCG revaccination, following primary vaccination in infancy, could be efficacious among TST-negative adolescents as they move into adulthood, the period of highest risk for pulmonary disease. To inform continuing debate about revaccination, this paper assesses the effectiveness and cost-effectiveness of revaccinating adolescents in a setting with intense transmission—Cape Town, South Africa. For a cost of revaccination in the range US$1–10 per person, and vaccine efficacy between 10% and 80% with protection for 10 years, the incremental cost per year of healthy life recovered (disability-adjusted life years, DALY) in the vaccinated population lies between US$116 and US$9237. The intervention is about twice as cost-effective when allowing for the extra benefits of preventing transmission, with costs per DALY recovered in the range US$52–$4540. At 80% efficacy, revaccination averted 17% of cases. Under the scenarios investigated, BCG revaccination is cost-effective against international benchmarks, though not highly effective. Cost-effectiveness ratios would be more favourable if we also allow for TB cases averted by preventing transmission to HIV-positive people, for the protection of HIV-negative people who later acquire HIV infection, for the possible non-specific benefits of BCG, for the fact that some adolescents would receive BCG for the first time, and for cost sharing when BCG is integrated into an adolescent immunization programme. These findings suggest, subject to further evaluation, that BCG revaccination could be cost-effective in some settings.
