Village AIDS committees (VAC) were formed by the Tanzanian government in 2003 to provide HIV education to their communities. However, their potential has not been realised due to their limited knowledge and misconceptions surrounding HIV, which could be addressed through training of VAC members. In an attempt to increase HIV knowledge levels and address common misconceptions amongst the VACs, an HIV curriculum was delivered to members in rural north western Tanzania.An evaluation of HIV knowledge was conducted prior to and post-delivery of HIV training sessions, within members of three VACs in Kisesa ward. Quantitative surveys were used with several open-ended questions to identify local misconceptions and evaluate HIV knowledge levels. Short educational training sessions covering HIV transmission, prevention and treatment were conducted, with each VAC using quizzes, role-plays and participatory learning and action tools. Post-training surveys occurred up to seven days after the final training session.Before the training, "good" HIV knowledge was higher amongst men than women (p = 0.041), and among those with previous HIV education (p = 0.002). The trade-centre had a faster turn-over of VAC members, and proximity to the trade-centre was associated with a shorter time on the committee.Training improved HIV knowledge levels with more members achieving a "good" score in the post-training survey compared with the baseline survey (p = < 0.001). The training programme was popular, with 100% of participants requesting further HIV training in the future and 51.7% requesting training at three-monthly intervals.In this setting, a series of HIV training sessions for VACs demonstrated encouraging results, with increased HIV knowledge levels following short educational sessions. Further work is required to assess the success of VAC members in disseminating this HIV education to their communities, as well as up-scaling this pilot study to other regions in Tanzania with different misconceptions.
The expansion in the provision of life-saving antiretroviral therapy (ART) in sub-Saharan Africa over the past 15 years has been an unprecedented achievement for public health. By the end of 2015, an estimated 10.3 million persons living with HIV (PLHIV) were receiving ART in southern and eastern Africa, the most affected region in the world. Just over half of all PLHIV in the region are now receiving ART, more than double the number just 3 years earlier.1
ART scale-up has dramatically reduced HIV-related mortality and morbidity, bringing countless social and economic benefits to communities that had been hard hit by the epidemic. The network for Analysing Longitudinal Population data on HIV/AIDS (ALPHA), a collaboration among 10 health and demographic surveillance system (HDSS) sites in east and southern Africa, has been investigating declines in adult mortality and their causes in seven countries (www.lshtm.ac.uk/alpha).2 Recent analyses from seven sites indicate a substantial impact of HIV treatment programmes on adult mortality following the expansion of ART, with declines ranging from 58% to 84%.3
Despite this progress, there remains a substantial deficit in overall life expectancy among adults living with HIV, with their survival between 5 and 10 years less than among uninfected adults.4 These ‘excess’ deaths among PLHIV are occurring due to late diagnosis, poor linkage to care and treatment, and ART interruptions.5 By the end of 2015, an estimated 44% of PLHIV in southern and eastern Africa remained undiagnosed,6 and rates of linkage to care after diagnosis range widely from 17% to 78%, while ART initiation among those eligible for treatment ranges from 14% to 95%.7 A number of studies have documented reasons for delays in testing, and initiating and adhering to treatment including beliefs that treatment is for people who are sick, fear of side …
Introduction: The traditional “one-size-fits-all” model of HIV care whereby people living with HIV (PLWH) have regular individual clinical visits does not reflect the various preferences and needs of PLWH and stretches the capacity of health facilities (HFs). Little is known about the availability and the experience of differentiated HIV care delivery in the rural areas of Zimbabwe.Methods: We used a mixed-method approach to collect data from clients and providers at 26 HFs in Zimbabwe in 2019. We collected quantitative data about antiretroviral therapy (ART) delivery and time spent at the HF during a visit from one representative healthcare providers (HCP) and a stratified sample of PLWH at each HF. We performed semi-structured interviews among HCPs and focus group discussions (FGDs) among PLWH to collect information about the implementation of differentiated ART delivery (DART) models and their experience. We performed linear regression models to assess factors associated with the time spent in the HFs. We analyzed the interviews using an inductive approach. Transcripts were coded and constricted down to themes significant to the research objectives.Results: The majority (77%) of participating HFs offered at least one of the five DART models recommended in Zimbabwe: 13 (50%) offered community ART refill group (CARG), 1 (4%) club refill, 6 (23%) family refill, and 8 (31%) fast-track refill models. Mobile outreach was not available at any participating HF. In an unadjusted linear model, PLWH enrolled in the fast-track refill model spent 0.40 (95% confidence interval (CI): 0.15-0.56) less time at the HF than PLWH on routine care, whereas PLWH in the family refill model and delegated to go to the HF spent 2.63 (95% CI 1.42-4.88) more time at the HF during visit. Confidentiality and disclosure concerns were highlighted as the major barriers affecting the implementation of DART models, together with travel costs and waiting times. HCPs reported on the challenge of excessive workloads. Fast-track refill was perceived as the most adapted DART model to meet clients’ needs, followed by CARG and family refill.Conclusions: Confidentiality, travel costs and waiting times are key elements to consider in the implementation of differentiated care in rural Zimbabwe. More implementation research is needed to support the roll-out of differentiated HIV services in that region, especially DART models addressing the needs of PLWH. Our study supports the call for personalized care at ART programs in rural Africa.
The Network for Analysing Longitudinal Population-based HIV/AIDS data on Africa (ALPHA Network, http://alpha.lshtm.ac.uk/) brings together ten population-based HIV surveillance sites in eastern and southern Africa, and is coordinated by the London School of Hygiene and Tropical Medicine (LSHTM).It was established in 2005 and aims to (i) broaden the evidence base on HIV epidemiology for informing policy, (ii) strengthen the analytical capacity for HIV research, and (iii) foster collaboration between network members.All study sites, some starting in the late 1980s and early 1990s, conduct demographic surveillance in populations that range from approximately 20 to 220 thousand individuals.In addition, they conduct population-based surveys with HIV testing, and verbal autopsy interviews with relatives of deceased residents.ALPHA Network datasets have been used for studying HIV incidence, sexual behaviour and the effects of HIV on mortality, fertility, and household composition.One of the network's substantive focus areas is the monitoring of AIDS mortality and HIV services coverage in the era of antiretroviral therapy.Service use data are retrospectively recorded in interviews and supplemented by information from record linkage with medical facilities in the surveillance areas.Data access is at the discretion of each of the participating sites, but can be coordinated by the network.
Background: HIV/AIDS programmes and organisations around the world use routinely updated estimates of the UNAIDS 90-90-90 targets to track progress and prioritise further programme implementation. Any bias in these estimates has the potential to mislead organisations on where gaps exist in HIV testing and treatment programmes.Objective: To measure the extent of undisclosed HIV testing history and its impact on estimating the proportion of people living with HIV (PLHIV) who know their HIV status (the 'first 90' of the UNAIDS 90-90-90 targets).Methods: We conducted a retrospective cohort study using population-based HIV serological surveillance conducted between 2010 and 2016 and linked, directly observed HIV testing records in Kisesa, Tanzania. Generalised estimating equations logistic regression models were used to detect associations with non-disclosure of HIV testing history adjusting for demographic, behavioural, and clinical characteristics. We compared estimates of the 'first 90' using self-reported survey data only and augmented estimates using information from linked records to quantify the absolute and relative impact of undisclosed HIV testing history.Results: Numbers of participants in each of the survey rounds ranged from 7171 to 7981 with an average HIV prevalence of 6.9%. Up to 33% of those who tested HIV-positive and 34% of those who tested HIV-negative did not disclose their HIV testing history. The proportion of PLHIV who reported knowing their status increased from 34% in 2010 to 65% in 2016. Augmented estimates including information from directly observed testing history resulted in an absolute impact of 6.7 percentage points and relative impact of 12.4%.Conclusions: In this population, self-reported testing history in population-based HIV serological surveys under-estimated the percentage of HIV positives that are diagnosed by a relative factor of 12%. Research should be employed in other surveillance systems that benefit from linked data to investigate how bias may vary across settings.
Abstract Objective To analyse survival and retention rates of the Tanzanian care and treatment programme. Methods Routine patient‐level data were available from 101 of 909 clinics. Kaplan–Meier probabilities of mortality and attrition after ART initiation were calculated. Mortality risks were corrected for biases from loss to follow‐up using Egger’s nomogram. Smoothed hazard rates showed mortality and attrition peaks. Cox regression identified factors associated with death and attrition. Median CD4 counts were calculated at 6 month intervals. Results In 88,875 adults, 18% were lost to follow up 12 months after treatment initiation, and 36% after 36 months. Cumulative mortality reached 10% by 12 months (15% after correcting for loss to follow‐up) and 14% by 36 months. Mortality and attrition rates both peaked within the first six months, and were higher among males, those under 45 kg and those with CD4 counts below 50 cells/μl at ART initiation. In the first year on ART, median CD4 count increased by 126 cells/μl, with similar changes in both sexes. Conclusion Earlier diagnoses through expanded HIV testing may reduce high mortality and attrition rates if combined with better patient tracing systems. Further research is needed to explore reasons for attrition.
Integration of HIV with other primary health services, including sexual and reproductive health (SRH) care, is being widely promoted in sub-Saharan Africa. However, evidence on its benefits is equivocal, and some studies indicate client preferences for stand-alone HIV services. A comparative case study investigated the relationship between integration and client satisfaction across different models of care in Swaziland: two clinics integrated with SRH services, and two stand-alone HIV clinics. An exit survey (n=602) measured satisfaction across model using logistic regression. In-depth interviews (n=22), repeated three times, explored satisfaction and how it was influenced by integration or not. Satisfaction was highest at the fully stand-alone clinic; in multivariable models, clients there were more satisfied than partially integrated and partially stand-alone sites (adjusted odds ratio [aOR] 0.45, 95% confidence interval [CI] 0.25-0.81; and aOR 0.53, 95% CI 0.31-0.90, respectively); there was no difference between the fully integrated and fully stand-alone sites. Qualitative analysis suggested that satisfaction was constituted by eleven dimensions of care, including access to HIV medication, interpersonal care, efficiency, and confidentiality. Some dimensions were positively influenced by integration, while others were positively influenced by stand-alone care; some were not influenced by integration at all. Assumptions on the inherent value of integrated care were challenged in this high HIV prevalence setting, where stand-alone HIV care could be equally if not more satisfying to many clients. Those aiming to scale-up access to HIV care in this region may need to consider providing a variety of treatment models for clients with different health care needs.
Abstract Background Despite the introduction of free antiretroviral therapy (ART), the use of voluntary counselling and testing (VCT) services remains persistently low in many African countries. This study investigates how prior experience of HIV and VCT, and knowledge about HIV and ART influence VCT use in rural Tanzania. Methods In 2006–7, VCT was offered to study participants during the fifth survey round of an HIV community cohort study that includes HIV testing for research purposes without results disclosure, and a questionnaire covering knowledge, attitudes and practices around HIV infection and HIV services. Categorical variables were created for HIV knowledge and ART knowledge, with “good” HIV and ART knowledge defined as correctly answering at least 4/6 and 5/7 questions about HIV and ART respectively. Experience of HIV was defined as knowing people living with HIV, or having died from AIDS. Logistic regression methods were used to assess how HIV and ART knowledge, and prior experiences of HIV and VCT were associated with VCT uptake, with adjustment for HIV status and socio-demographic confounders. Results 2,695/3,886 (69%) men and 2,708/5,575 women (49%) had “good” HIV knowledge, while 613/3,886 (16%) men and 585/5575 (10%) women had “good” ART knowledge. Misconceptions about HIV transmission were common, including through kissing (55% of women, 43% of men), or mosquito bites (42% of women, 34% of men). 19% of men and 16% of women used VCT during the survey. After controlling for HIV status and socio-demographic factors, the odds of VCT use were lower among those with poor HIV knowledge (aOR = 0.5; p = 0.01 for men and aOR = 0.6; p < 0.01 for women) and poor ART knowledge (aOR = 0.8; p = 0.06 for men, aOR = 0.8; p < 0.01 for women), and higher among those with HIV experience (aOR = 1.3 for men and aOR = 1.6 for women, p < 0.01) and positive prior VCT experience (aOR = 2.0 for all men and aOR = 2.0 for HIV-negative women only, p < 0.001). Conclusions Two years after the introduction of free ART in this setting, misconceptions regarding HIV transmission remain rife and knowledge regarding treatment is worryingly poor, especially among women and HIV-positive people. Further HIV-related information, education and communication activities are urgently needed to improve VCT uptake in rural Tanzania.
Integrating HIV with primary health services has the potential to reduce HIV-related stigma through delivering care in settings disassociated with HIV. This study investigated the relationship between integrated care and felt stigma. The study design was a comparative case study of four models of HIV care in Swaziland, ranging from fully integrated to fully stand-alone HIV care.An exit survey (N=602) measured differences in felt stigma across model of care; the primary outcome "perception of HIV status exposure through clinic attendance" was analyzed using multivariable logistic regression. In-depth interviews (N=22) explored whether and how measured differences in stigma experiences were related to service integration.There were significant differences in perceived status exposure across models of care. After adjustment for potential confounding between sites, those at a partially integrated site and a partially stand-alone site had greater odds of perceived status exposure than those at the fully stand-alone site (aOR 3.33, 95% CI 1.98-5.60; and aOR 11.84, 95% CI 6.89-20.36, respectively). There was no difference between the fully stand-alone and the fully integrated clinic. Qualitative data suggested that many clients at HIV-only sites felt greater confidentiality knowing that those around them were positive, and support was gained from other HIV care clients. Confidentiality was maintained in various ways, even in stand-alone sites, through separate waiting areas for HIV testing and HIV treatment, and careful clinic and room labelling.The relationship between model of care and stigma was complex, and the hypothesis that stigma is higher at stand-alone sites did not hold true in this high prevalence setting. Policy-makers should ensure that service integration does not increase stigma, in particular within partially integrated models of care.
Abstract Irregular or delayed attendance at HIV treatment clinics among HIV-positive individuals can have negative implications for clinical outcomes and may ultimately undermine the effectiveness of national treatment programmes. This study explores factors influencing attendance at HIV clinic appointments among patients in a rural ward in north-west Tanzania. Forty-two in-depth interviews (IDI) and four focus group discussions were conducted with HIV-infected persons who had been referred to a nearby antiretroviral therapy (ART) clinic, and IDI were undertaken with 11 healthcare workers involved in diagnosis, referral and care of HIV-positive patients. The Health Belief Model was applied to explore the role of health-related beliefs and the perceived barriers and benefits associated with regular clinic attendance. Perceived susceptibility to HIV-related illnesses emerged as an important factor influencing clinic attendance, and was often manifest through expressions of acceptance or denial of HIV status and knowledge of HIV disease progression. Denial of HIV status was often associated with using alternative healers, and could occur prior to, during, or after starting ART. Perceptions of illness severity also influenced HIV clinic attendance, and often evolved in relation to changes in physical symptoms. Barriers to clinic attendance frequently included health systems factors, while physical and social benefits encouraged regular clinic attendance. Self-confidence in being able to sustain clinic attendance was often determined by patients' expectations or experiences of family support. These findings suggest that multi-faceted interventions are required to promote regular HIV clinic attendance, including on-going education, counselling and support in both clinic and community settings. These interventions also need to recognise the evolving needs of patients that accompany changes in physical health, and should address local beliefs around HIV aetiology. Decentralisation of HIV services to rural communities should be considered as a priority to redress the balance between perceived barriers to, and benefits of accessing HIV treatment programmes.
