The role of social capital in successful adherence to antiretroviral therapy in Africa

Feasibility and acceptability of B6: a social capital program for young Black gay, bisexual and other men who have sex with men living with HIV

Young Black gay, bisexual and other men who have sex with men (YB-GBMSM) are disproportionately burdened by HIV and often exhibit suboptimal engagement in HIV care. With the goal of increasing engagement in HIV care, we designed a culturally specific, theory-based group-level program, Brothers Building Brothers by Breaking Barriers (B6), which aimed to strengthen resilience and social capital among YB-GBMSM living with HIV. We conducted a pilot trial to evaluate the program's acceptability and feasibility. Through clinic-based recruitment and community outreach events, we recruited and enrolled 71 YB-GBMSM into the study. Participants were randomized to either the B6 program or a control comparison program. Post-session evaluation surveys and in-depth qualitative interviews showed B6 to have high levels of acceptability and satisfaction. Specifically, participants described benefits to interacting in a group with other YB-GBMSM, and several described increased comfort with their own gay identities after participation. No adverse events or safety concerns were reported. However, there were challenges to feasibility, as reflected in recruitment and retention rates. The B6 program was highly acceptable among YB-GBMSM living with HIV; however, innovative program delivery methods and implementation strategies will be needed to improve recruitment and retention in future implementation of B6.

Dehumanizing language, motherhood in the context of HIV, and overcoming HIV stigma - the voices of Rwandan women with HIV: A focus group study

BACKGROUND

Stigma is an underlying cause of health inequities, and a major barrier to HIV prevention, care, and treatment. Experiences of HIV stigma have been shown to reduce engagement in care across the HIV care continuum, from testing and diagnosis to long-term retention in care and anti-retroviral therapy adherence. In Rwanda, approximately 130,000 women are living with HIV, representing a prevalence rate (3.7%) which is substantially higher than Rwandan men (2.2%). Both the national Rwanda and City of Kigali HIV and AIDS strategic plans identify stigma as a key concern for reducing the burden of HIV.

OBJECTIVES

The first objective of this study was to understand the sources of HIV-related stigma among women living with HIV in Rwanda. The second objective was to understand the cultural, linguistic, and contextual context of HIV-related stigma and the intersection of HIV-related stigma to the HIV care continuum (engagement in care, medication/treatment adherence) among women with HIV in Rwanda.

DESIGN

This study used a cross-sectional, qualitative design.

SETTING AND PARTICIPANTS

Three-three women from urban and rural settings in Rwanda were recruited from public HIV treatment and care centers to participate in this study.

METHOD

Focus groups discussions, guided by a structured interview guide, were used to collect qualitative data. Framework analysis was used to analyze the data, which was collected during July 2018.

RESULTS

The participants in this study highlighted that Rwandan women with HIV experience all forms of stigma - enacted, anticipated, perceived, and internalized - associated with HIV as well as structural stigma. Further, three major themes - dehumanizing language, importance of motherhood in the context of HIV, and overcoming HIV stigma - emerged from the data.

CONCLUSION

The results of this study are among the few to give voice and perspective to the stigma experiences of Rwandan women with HIV. The women with HIV participating in this study shed light on the pervasive and culturally constructed effects of stigma that continue to exist. Further, the findings from this study highlighted the significant intersection of the role dehumanizing language experienced by Rwandan women with HIV. Additionally, the intersectional identities of being a woman with HIV and a mother and their relationship to societal and cultural norms and expectations must be considered concurrently. Finally, the beneficial effects of support groups was identified as key in helping Rwandan women with HIV to accept self.

Out-of-Facility Multimonth Dispensing of Antiretroviral Treatment: A Pooled Analysis Using Individual Patient Data From Cluster-Randomized Trials in Southern Africa

BACKGROUND

Out-of-facility multi-month dispensing (MMD) is a differentiated service delivery model which provides antiretroviral treatment (ART) at intervals of up to 6 monthly in the community. Limited randomized evidence investigating out-of-facility MMD is available. We evaluated participant outcomes and compared out-of-facility MMD models using data from cluster-randomized trials in Southern Africa.

SETTING

Eight districts in Zimbabwe and Lesotho.

METHODS

Individual-level participant data from 2 cluster-randomized trials that included stable adults receiving ART at 60 facilities were pooled. Both trials had 3 arms: ART collected 3-monthly at healthcare facilities (3MF, control); ART provided three-monthly in community ART groups (CAGs) (3MC); and ART provided 6-monthly in either CAGs or on an individual provider-patient basis (6MC). Participant retention, viral suppression and incidence of unscheduled facility visits were compared.

RESULTS

Ten thousand one hundred thirty-six participants were included, 3817 (37.7%), 2893 (28.5%) and 3426 (33.8%) in arms 3MF, 3MC and 6MC, respectively. After 12 months, retention was non-inferior for 3MC (95.7%) vs. 3MF (95.0%) {adjusted risk difference (aRD) = 0.3 [95% confidence interval (CI): -0.8 to 1.4]}; and 6MC (95.1%) vs. 3MF [aRD = -0.2 (95% CI: -1.4 to 1.0)]. Retention was greater amongst intervention arm participants in CAGs versus 6MC participants not in CAGs, aRD = 1.5% (95% CI: 0.2% to 2.9%). Viral suppression was excellent (≥98%) and unscheduled facility visits were not increased in the intervention arms.

CONCLUSIONS

Three and 6-monthly out-of-facility MMD was non-inferior versus facility-based care for stable ART patients. Out-of-facility 6-monthly MMD should incorporate small group peer support whenever possible.

A framework for identifying and mitigating the equity harms of COVID-19 policy interventions

BACKGROUND

Coronavirus disease 2019 (COVID-19) is a global pandemic. Governments have implemented combinations of "lockdown" measures of various stringencies, including school and workplace closures, cancellations of public events, and restrictions on internal and external movements. These policy interventions are an attempt to shield high-risk individuals and to prevent overwhelming countries' healthcare systems, or, colloquially, "flatten the curve." However, these policy interventions may come with physical and psychological health harms, group and social harms, and opportunity costs. These policies may particularly affect vulnerable populations and not only exacerbate pre-existing inequities but also generate new ones.

METHODS

We developed a conceptual framework to identify and categorize adverse effects of COVID-19 lockdown measures. We based our framework on Lorenc and Oliver's framework for the adverse effects of public health interventions and the PROGRESS-Plus equity framework. To test its application, we purposively sampled COVID-19 policy examples from around the world and evaluated them for the potential physical, psychological, and social harms, as well as opportunity costs, in each of the PROGRESS-Plus equity domains: Place of residence, Race/ethnicity, Occupation, Gender/sex, Religion, Education, Socioeconomic status, Social capital, Plus (age, and disability).

RESULTS

We found examples of inequitably distributed adverse effects for each COVID-19 lockdown policy example, stratified by a low- or middle-income country and high-income country, in every PROGRESS-Plus equity domain. We identified the known policy interventions intended to mitigate some of these adverse effects. The same harms (anxiety, depression, food insecurity, loneliness, stigma, violence) appear to be repeated across many groups and are exacerbated by several COVID-19 policy interventions.

CONCLUSION

Our conceptual framework highlights the fact that COVID-19 policy interventions can generate or exacerbate interactive and multiplicative equity harms. Applying this framework can help in three ways: (1) identifying the areas where a policy intervention may generate inequitable adverse effects; (2) mitigating the policy and practice interventions by facilitating the systematic examination of relevant evidence; and (3) planning for lifting COVID-19 lockdowns and policy interventions around the world.

Households in HIV Care: Designing an Intervention to Stimulate HIV Competency in Households in South Africa

Despite the Universal Test and Treat program and widespread antiretroviral treatment rollout, South Africa is still facing HIV prevention and treatment challenges, which are aggravated by human resource shortages in the healthcare sector. Individual- and community-level responses to these HIV-related challenges are increasingly being explored, for example, in community and home-based care. The role of the household as a crucial mediating social level has, however, largely been omitted. This paper outlines the design of an intervention to stimulate the involvement of the household in support for people living with HIV in South Africa. The 6SQuID model guided the intervention development process in four phases: (1) formative research, theory formulation, and a review of the existing literature, (2) integration of the results from the formative research into the "Positive Communication Process" (P2CP model) as a mechanism of change, (3) design of a community-health-worker-led intervention as the way to deliver the change mechanism, and (4) testing and revision of the developed intervention material-called Sinako-in a small-scale pilot study. The Sinako intervention anticipates that the future of chronic HIV care in resource-constrained settings will need to integrate the patient's household into the fight against HIV.

The effectiveness and cost-effectiveness of community-based support for adolescents receiving antiretroviral treatment: an operational research study in South Africa

Introduction

Adolescents and youth receiving antiretroviral treatment (ART) in sub‐Saharan Africa have high attrition and inadequate ART outcomes, and evaluations of interventions improving ART outcomes amongst adolescents are very limited. Sustainable Development Goal (SDG) target 3c is to substantially increase the health workforce in developing countries. We measured the effectiveness and cost‐effectiveness of community‐based support (CBS) provided by lay health workers for adolescents and youth receiving ART in South Africa.

Methods

A retrospective cohort study including adolescents and youth who initiated ART at 47 facilities. Previously unemployed CBS‐workers provided home‐based ART‐related education, psychosocial support, symptom screening for opportunistic infections and support to access government grants. Outcomes were compared between participants who received CBS plus standard clinic‐based care versus participants who received standard care only. Cumulative incidences of all‐cause mortality and loss to follow‐up (LTFU), adherence measured using medication possession ratios (MPRs), CD4 count slope, and virological suppression were analysed using multivariable Cox, competing‐risks regression, generalized estimating equations and mixed‐effects models over five years of ART. An expenditure approach was used to determine the incremental cost of CBS to usual care from a provider perspective. Incremental cost‐effectiveness ratios were calculated as annual cost per patient‐loss (through death or LTFU) averted.

Results

Amongst 6706 participants included, 2100 (31.3%) received CBS. Participants who received CBS had reduced mortality, adjusted hazard ratio (aHR) = 0.52 (95% CI: 0.37 to 0.73; p < 0.0001). Cumulative LTFU was 40% lower amongst participants receiving CBS (29.9%) compared to participants without CBS (38.9%), aHR = 0.60 (95% CI: 0.51 to 0.71); p < 0.0001). The effectiveness of CBS in reducing attrition ranged from 42.2% after one year to 35.9% after five years. Virological suppression was similar after three years, but after five years 18.8% CBS participants versus 37.2% non‐CBS participants failed to achieve viral suppression, adjusted odds ratio = 0.24 (95% CI: 0.06 to 1.03). There were no significant differences in MPR or CD4 slope. The cost of CBS was US$49.5/patient/year. The incremental cost per patient‐loss averted was US$600 and US$776 after one and two years, respectively.

Conclusions

CBS for adolescents and youth receiving ART was associated with substantially reduced patient attrition, and is a low‐cost intervention with reasonable cost‐effectiveness that can aid progress towards several health, economic and equality‐related SDG targets.

The Longitudinal Association between Social Support on HIV Medication Adherence and Healthcare Utilization in the Women's Interagency HIV Study

Social support is associated with HIV-related health outcomes. However, few studies have explored this longitudinally. We assessed psychometric properties of the Medical Outcomes Study's Social Support Survey among women in the Women's Interagency HIV Study, and explored the longitudinal effects of social support on HIV medication adherence (HIV-positive women) and healthcare utilization (HIV-positive and negative women). The 15 questions loaded into two factors, with Cronbach's Alpha > 0.95. Over 3 years, perceived emotional support was associated with optimal medication adherence (OR 1.19, 95% CI 1.10-1.28) and healthcare utilization (OR 1.16, 95% CI 1.05-1.27), and tangible social support with adherence only (OR 1.18, 95% CI 1.08-1.27) when controlling for covariates, including core sociodemographic characteristics and depressive symptoms. Interventions to further understand the drivers of sub-types of social support as well as enhance sustained social support may assist with optimizing care of women with and at risk for HIV.

Barriers on the pathway to survival for children dying from treatable illnesses in Inhambane province, Mozambique

BACKGROUND

Mozambique has one of the highest under-5 mortality rates in the world. Community health workers (CHWs) are deployed to increase access to care; in Mozambique they are known as agentes polivalentes elementares (APEs). This study aimed to investigate child deaths in an area served by APEs by analysing the causes, care seeking patterns, and the influence of social capital.

METHODS

Caregivers of children under-5 who died in 2015 in Inhambane province, Mozambique, were interviewed using Verbal Autopsy/Social Autopsy (VA/SA) tools with a social capital module. VA data were analysed using the WHO InterVA analytical tool to determine cause of death. SA was analysed using the INDEPTH SA framework for illnesses lasting no more than three weeks. Social capital scores were calculated.

RESULTS

117 child deaths were reported; VA/SA was conducted for 115. Eighty-five had died from an acute illness lasting no more than three weeks, which in most cases could have been treated at community level; 50.6% died from malaria, 11.8% from HIV/AIDS, and 9.4% for each of diarrhoea and acute respiratory infections. In 35.3% the caregiver only noticed that the child was sick when symptoms of very severe illness developed. One in four children were never taken outside the home before dying. Sixteen children were first taken to an APE; of these 7 had signs of very severe illness. Caregivers who waited to seek care until the illness was very severe had a lower social capital score. The mean travel time to go to the APE was 2hrs 50min, which was not different from any other provider. Most received treatment from the APE, 3 were referred. The majority went to another provider after the APE; most to a health centre.

CONCLUSIONS

The leading causes of death in children under-5 can be detected, treated or referred by APEs. Major care seeking delays took place in the home, largely due to lack of early disease recognition and late decision-making. Low social capital, distance to APEs and to referral facilities likely contribute to these delays. Increasing caregiver illness awareness is urgently needed, as well as stronger referral linkages. A review of the geographical coverage and scope of work of APEs should be conducted.

Social Capital Associated with Quality of Life among People Living with HIV/AIDS in Nanchang, China

Background: This study aims to explore the relationship between quality of life (QOL) and social capital factors among "people living with HIV/AIDS" (PLWHA), in order to improve their quality of life and help them to release AIDS discrimination. Methods: A cross-sectional survey with 225 PLWHA was done in Nanchang, China, between January and June of 2015. Questionnaires consisted of a socio-demographic questionnaire, Personal Social Capital Scale and Medical Outcomes Study HIV Health Survey. To identify social capital factors influencing QOL among PLWHA, t-test and multiple linear regression were used as statistical tools. The analysis of data was conducted using SPSS 22.0 with a significant value of p < 0.05. Results: The scores of total social capital, bonding social capital and bridging social capital were 23.68 ± 5.55, 14.11 ± 3.40 and 9.46 ± 3.43 respectively. The scores of Physical Health Summary (PHS) and Mental Health Summary (MHS) were 51.88 ± 7.04 and 49.29 ± 6.60. Multiple linear regression analysis showed that age (B = -0.137, p = 0.020), income (B = 0.2170, p ≤ 0.001), employment (B = 0.112, p = 0.043) and bonding social capital (B = 0.178, p = 0.001) had significant effects on PHS. Bonding social capital was the most important influencing factor for MHS (B = 0.506, p < 0.001). There was no significant relationship between bridging social capital and QOL (p > 0.05). Conclusions: The PLWHA community has low social capital and a poor QOL in Nanchang. Bonding social capital had a positive impact on the QOL of PLWHA. There is an urgent need to build a better social support system based on bonding social capital for PLWHA. It is worth further exploring to identify how to make full use of bridging social capital for improving QOL among PLWHA.

Brothers Building Brothers by Breaking Barriers: development of a resilience-building social capital intervention for young black gay and bisexual men living with HIV

Young Black gay/bisexual and other men who have sex with men (YB-GBMSM) are disproportionately impacted by HIV/AIDS. Novel intervention strategies are needed to optimize engagement in HIV care for this population. We sought to develop a group-level intervention to enhance resilience by augmenting social capital (defined as the sum of resources in an individual's social network) among YB-GBMSM living with HIV, with the ultimate goal of improving engagement in HIV care. Our multiphase, community-based participatory research (CBPR) intervention development process included: (1) Development and maintenance of a youth advisory board (YAB) comprised of YB-GBMSM living with HIV; (2) Qualitative in-depth interviews with YB-GBMSM living with HIV; (3) Qualitative in-depth interviews with care and service providers at clinics and community-based organizations; and (4) Collaborative development of intervention modules and activities with our YAB, informed by social capital theory and our formative research results. The result of this process is Brothers Building Brothers By Breaking Barriers, a two-day, 10-module group-level intervention. The intervention does not focus exclusively on HIV, but rather takes a holistic approach to supporting youth and enhancing resilience. Intervention modules aim to develop resilience at the individual level (exploration of black gay identity, development of critical self-reflection and coping skills), social network level (exploring strategies for navigating family and intimate relationships) and community level (developing strategies for navigating clinical spaces and plans for community participation). Most intervention activities are interactive, in order to facilitate new social network connections - and accompanying social capital - within intervention groups. In summary, our intensive CBPR approach resulted in a novel, culturally-specific intervention designed to enhance HIV care engagement by augmenting resilience and social capital among YB-GBMSM living with HIV.

Prevalence of depressive symptoms and associated factors among adolescents living with HIV/AIDS in South Western Uganda

Adolescents living with HIV (ALHIV) are prone to depression, which can have detrimental effects including disease progression, poor treatment adherence and mortality. We aimed to determine the prevalence of depressive symptoms and their associated factors among ALHIV in Uganda. We conducted a cross-sectional survey among ALHIV (10-19 years) attending urban and rural clinics in Mbarara, Uganda between March and May 2017. Presence of depressive symptoms was assessed using the Centre for Epidemiological Studies' Depression scale. We interviewed 336 adolescents with a median age of 13 years, 62% of whom were female. A third (37%) had disclosed their HIV/AIDS status and 13% were sexually active. Overall, 154 (∼46%, [95% CI: 40.5-51.2]) had depressive symptoms. On bivariate analysis, the odds of having depressive symptoms were higher among adolescents who were ≥ 15 years, had disclosed HIV status, traveled >30 min for routine care and had risky sexual practices. On multiple variable analysis, only travel time to the clinic of >30 min was independently associated with depressive symptoms (AOR = 1.6 [95% CI: 1.02-2.7]). With the high prevalence of depressive symptoms among ALHIV in Uganda, screening and prompt treatment of depression should be incorporated within their routine care.

Parental obligations, care and HIV treatment: How care for others motivates self-care in Zimbabwe

This article examines how parental obligations of care intersect with HIV treatment-seeking behaviours and retention. It draws on qualitative data from eastern Zimbabwe, produced from 65 interviews. Drawing on theories of practice and care ethics, our analysis revealed that norms of parental obligation and care acted as key motivators for ongoing engagement with HIV services and treatment. Parents' attentiveness to the future needs of their children (caring about), and sense of obligation (taking care of) and improved ability to care (caregiving) following treatment initiation, emerged as central to understanding their drive for self-care and engagement with HIV services.

Social capital and resilience among people living on antiretroviral therapy in resource-poor Uganda

BACKGROUND

Despite the national roll-out of free HIV medicines in Uganda and other sub-Saharan African countries, many HIV positive patients on antiretroviral therapy (ART) are at risk of non-adherence due to poverty and other structural and health system related constraints. However, several patients exhibit resilience by attaining and sustaining high levels of adherence amid adversity. Social capital, defined as resources embedded within social networks, is key in facilitating resilience but the mechanism through which it operates remains understudied. This article provides insights into mechanisms through which social capital enables patients on ART in a resource-poor setting to overcome risk and sustain adherence to treatment.

METHODOLOGY

The article draws from an ethnographic study of 50 adult male and female HIV patients enrolled at two treatment sites in Uganda, 15 of whom were followed-up for an extended period of six months for narrative interviews and observation. The patients were selected purposively on the basis of socio-demographic and treatment related criteria.

FINDINGS

Social capital protects patients on ART against the risk of non-adherence in three ways. 1) It facilitates access to scarce resources; 2) encourages HIV patients to continue on treatment; and 3) averts risk for non-adherence.

CONCLUSIONS

Social capital is a key resource that can be harnessed to promote resilience among HIV patients in a resource-limited setting amid individual, structural and health system related barriers to ART adherence. Invigoration and maintenance of collectivist norms may however be necessary if its protective benefits are to be fully realized.

Ongoing Initiatives to Improve the Quality and Efficiency of Medicine Use within the Public Healthcare System in South Africa; A Preliminary Study

Introduction: South Africa has an appreciable burden of both communicable and non-communicable diseases as well as high maternal, neonatal, and child morbidity. In recent years there have been significant strides with improving the public health system, and addressing current inequalities, with the right to health a constitutional provision in South Africa. Initiatives include the introduction of National Health Insurance, programmes to enhance access to medicines for patients with chronic diseases, as well as activities to improve care in hospitals, including improving pharmacovigilance. Consequently, the objective of this paper is to review ongoing initiatives within the public healthcare sector in South Africa and their influence to provide future direction.

Method: Principally a structured review of current and planned activities.

Results: There have been a number of major activities and initiatives surrounding the availability and access to medicines in the public system in recent years in South Africa. This includes a National Surveillance Centre and an innovative early warning system for the supply of medicines as well as the development of a National Health Care Pricing Authority and initiatives to improve contracting. There have also been developments to improve the supply chain including instigating Medicine Procurement Units in the provinces and enhancing forecasting capabilities. Access to medicines is improving though the instigation of stable chronic disease management initiatives to increase the number of external pick-up points for medicines. There are also ongoing programmes to enhance adherence to medicines as well as enhance adherence to the Standard Treatment Guidelines and the Essential Medicines List with their increasing availability. In addition, there is a movement to enhance the role of health technology assessment in future decision making. Hospital initiatives include increased focus on reducing antimicrobial resistance through instigating stewardship programmes as well as improving adverse drug reaction reporting and associated activities.

Conclusion: Overall, there are an appreciable number of ongoing activities within the public healthcare system in South Africa attempting to ensure and sustain universal healthcare. It is too early to assess their impact, which will be the subject of future research.

Short message service (SMS) reminders and real-time adherence monitoring improve antiretroviral therapy adherence in rural Uganda

OBJECTIVE

To explore the effects of four types of short message service (SMS) plus real-time adherence monitoring on antiretroviral therapy (ART) adherence: daily reminders, weekly reminders, reminders triggered after a late or missed dose (delivered to patients), and notifications triggered by sustained adherence lapses (delivered to patient-nominated social supporters).

DESIGN

Pilot randomized controlled trial.

METHODS

Sixty-three individuals initiating ART received a real-time adherence monitor and were randomized (1 : 1 : 1): (1) Scheduled SMS reminders (daily for 1 month, weekly for 2 months), then SMS reminders triggered by a late or missed dose (no monitoring signal within 2 h of expected dosing); SMS notifications to social supporters for sustained adherence lapses (no monitoring signal for >48 h) added after 3 months. (2) Triggered SMS reminders starting at enrolment; SMS notifications to social supporters added after 3 months. (3) CONTROL: No SMS. HIV RNA was determined at 9 months. Percentage adherence and adherence lapses were compared by linear generalized estimating equations and Poisson regression, respectively.

RESULTS

Median age was 31 years, 65% were women, and median enrolment CD4 cell count was 322 cells/μl 97% took once daily tenofovir/emtricitabine/efavirenz. Compared to control, adherence was 11.1% higher (P = 0.04) and more than 48-h lapses were less frequent (IRR 0.6, P = 0.02) in the scheduled SMS arm. Adherence and more than 48-h lapses were similar in the triggered SMS arm and control. No differences in HIV RNA were seen.

CONCLUSION

Scheduled SMS reminders improved ART in the context of real-time monitoring. Larger studies are needed to determine the impact of triggered reminders and role of social supporters in improving adherence.

Does Social Participation Predict Better Health? A Longitudinal Study in Rural Malawi

Research on the relationship between social capital and individual health often suffers from important limitations. Most research relies on cross-sectional data, which precludes identifying whether participation predicts health and/or vice versa. Some important conceptualizations of social capital, like social participation, have seldom been examined. Little is known about participation and health in sub-Saharan Africa. Furthermore, both physical and mental health have seldom been tested together, and variation by age has rarely been examined. We use longitudinal survey data for 2,328 men and women from the Malawi Longitudinal Study of Families and Health, containing (1) several measures of social participation, (2) measures of physical and mental health, and (3) an age range of 15 to 80+ years. Our results differ by gender and age and for mental and physical health. We find that social participation is associated with better physical health but can predict worse mental health for Malawians.

Community-based accompaniment and psychosocial health outcomes in HIV-infected adults in Rwanda: a prospective study

We examined whether the addition of community-based accompaniment to Rwanda's national model for antiretroviral treatment (ART) was associated with greater improvements in patients' psychosocial health outcomes during the first year of therapy. We enrolled 610 HIV-infected adults with CD4 cell counts under 350 cells/μL initiating ART in one of two programs. Both programs provided ART and required patients to identify a treatment buddy per national protocols. Patients in one program additionally received nutritional and socioeconomic supplements, and daily home-visits by a community health worker ("accompagnateur") who provided social support and directly-observed ingestion of medication. The addition of community-based accompaniment was associated with an additional 44.3 % reduction in prevalence of depression, more than twice the gains in perceived physical and mental health quality of life, and increased perceived social support in the first year of treatment. Community-based accompaniment may represent an important intervention in HIV-infected populations with prevalent mental health morbidity.

Improved virological suppression in children on antiretroviral treatment receiving community-based adherence support: a multicentre cohort study from South Africa

Adherence to antiretroviral treatment (ART) is a challenge in childhood, and children on ART have reduced virological suppression compared to adults. This study evaluated the effect of community-based adherence support (CBAS) on virological outcomes amongst children receiving ART in four South African provinces. Patient Advocates are lay CBAS workers who provide adherence and psychosocial support for patients, undertaking home visits to address household challenges affecting adherence. Patient Advocates provide counselling for children's carers regarding adherence and psychosocial problems. A multicentre cohort study using routinely collected data was conducted at 57 public ART sites including ART-naive children (<16 years) starting ART. Virological suppression until four years of ART was compared between children who received and did not receive CBAS. Analyses were by intention-to-treat, controlling for confounding using multivariable generalised estimating equations. A total of 4853 children were included, of whom 982 (20.2%) received CBAS. The median baseline age was 6.3 years and the baseline CD4 cell percentage was 12.0%; both were equivalent between the two groups. CBAS children had more advanced baseline clinical disease (62.1% vs. 52.6% World Health Organisation stages III or IV; P < 0.0001). A total of 5908 viral load results were analysed. Virological suppression was 65.6% (95% confidence interval [CI]: 62.7-68.4%) vs. 55.5% (95% CI: 54.1-57.0%) in CBAS and non-CBAS children, respectively, at any time-point on treatment (P < 0.0001). In analyses controlling for baseline clinical, demographic, site-related variables and time on ART, children receiving CBAS were more likely to achieve virological suppression, adjusted odds ratio (aOR) 1.60 (95% CI: 1.35-1.89; P < 0.0001). The effect of CBAS increased in magnitude with increasing durations of ART, and CBAS particularly improved virological suppression in a higher-risk subgroup (children younger than two years, aOR 2.47 [95% CI: 1.59-3.84]). CBAS was associated with improved virological suppression in children receiving ART. Expanded implementation of this low-cost intervention should be considered in resource-poor settings.

Role of Education in HIV Clinical Outcomes in a Tuberculosis Endemic Setting

This study evaluated how educational attainment impacts clinical outcomes of HIV-positive patients in Durban, South Africa. The authors conducted a prospective study of 466 adult HIV-positive patients initiating antiretroviral therapy (ART) at an urban TB-HIV clinic from October 2004 to June 2007. The level of educational attainment (highest grade completed) was assessed at ART initiation. The authors measured tuberculosis treatment outcomes as well as death, lost to follow-up, viral suppression (HIV RNA <400 copies/mL), and immunologic response (CD4 ≥200 cells/mm(3)) at 6, 12, and 24 months after ART initiation. After 24 months of ART initiation, there were 43 deaths; viral suppression and immunologic response were observed in 88% and 83% of the remaining patients, respectively. The authors found no association between level of educational attainment and mortality (P = .12), loss to follow-up (P = .85), virologic response (P = .51), or immunologic response (P = .63). Similar findings were observed at 6 and 12 months post-ART initiation.

Living with HIV postdiagnosis: a qualitative study of the experiences of Nairobi slum residents

OBJECTIVES

To characterise the experiences of heterosexual men and women living with HIV postdiagnosis and explain these experiences in relation to their identity and sexuality.

DESIGN

Qualitative study using in-depth interviews and a theoretically informed biographic disruption theory.

SETTING

Interviews were conducted in two Nairobi slums (Kenya).

PARTICIPANTS

41 HIV-infected heterosexual men and women aged 18 years or older.

RESULTS

People living with HIV have divergent experiences surrounding HIV diagnosis. Postdiagnosis, there are multiple phases of identity transition, including status (non-)disclosure, and attempts at identity repair and normalcy. For some people, this process involves a transition to a new self-identity, incorporating both HIV and antiretroviral treatment (ART) into their lives. For others, it involves a partial transition, with some aspects of their prediagnosis identity persisting, and for others it involves a rejection of HIV identity. Those people who were able to incorporate HIV/AIDS in their identity, without it being disruptive to their biography, were pursuing safer sexual and reproductive lives. By contrast, those people with a more continuous biography continued to reflect their prediagnosis identity and sexual behaviour.

CONCLUSIONS

People living with HIV/AIDS (PLWHA) had to rework their sense of identity following diagnosis in the context of living in a slum setting. Men and women living with HIV in slums are poorly supported by health systems and services as they attempt to cope with a diagnosis of HIV. Given the availability of ART, health services and professionals need to support the rights of PLWHA to be sexually active if they want to and achieve their fertility goals, while minimising HIV transmission risk.

Antiretroviral therapy drug adherence in Rwanda: perspectives from patients and healthcare workers using a mixed-methods approach

Rwanda has achieved high enrollment into antiretroviral therapy (ART) programs but data on adherence after enrollment are not routinely collected. We used a mixed-methods approach (standardized questionnaires, pill counts, focus group discussions, and in-depth interviews) to determine levels of and barriers to ART adherence from the perspective of both patients and healthcare workers (HCW). Data were available from 213 patients throughout the first year on ART; 58 of them and 23 HCW participated in a qualitative sub-study. Self-reported adherence was high (96% of patients reporting more than 95% adherence), but adherence by pill count was significantly lower, especially in the first 3 months. In the standardized interviews, patients mostly reported that they "simply forgot" or "were away from home" as reasons for nonadherence. The qualitative research identified three interrelated constructs that appeared to negatively influence adherence: stigma, difficulty coming to terms with illness, and concealment of illness. Both standardized questionnaires and the qualitative research identified poverty, disruption to daily routines, factors related to regimen complexity and side effects, and service-related factors as barriers to adherence. We conclude that regular triangulation of different sources of adherence data is desirable to arrive at more realistic estimates. We propose that program monitoring and evaluation cycles incorporate more in-depth research to better understand concerns underlying reasons for nonadherence reported in routine monitoring.

Improved survival and antiretroviral treatment outcomes in adults receiving community-based adherence support: 5-year results from a multicentre cohort study in South Africa

INTRODUCTION

A large increase in lay health care workers has occurred in response to shortages of professional health care staff in sub-Saharan African antiretroviral treatment (ART) programs. However, little effectiveness data of the large-scale implementation of these programs is available. We evaluated the effect of a community-based adherence-support (CBAS) program on ART outcomes across 57 South African sites.

METHODS

CBAS workers provide adherence and psychosocial support for patients and undertake home visits to address household challenges affecting adherence. An observational multicohort study of adults enrolling for ART between 2004 and 2010 was performed. Mortality, loss to follow-up, and virological suppression were compared by intention to treat between patients who received and did not receive CBAS until 5 years of ART, using multiple imputation of missing covariate values.

RESULTS

Of the 66,953 patients who were included, 19,668 (29.4%) patients received CBAS and 47,285 (70.6%) patients did not. Complete-case covariate data were available for 54.3% patients. After 5 years, patient retention was 79.1% [95% confidence interval (CI): 77.7% to 80.4%] in CBAS patients versus 73.6% (95% CI: 72.6% to 74.5%) in non-CBAS patients; crude hazard ratio (HR) for attrition was 0.68 (95% CI: 0.65 to 0.72). Mortality and loss to follow-up were independently lower in CBAS patients, adjusted HR (aHR) was 0.65 (95% CI: 0.59 to 0.72) and 0.63 (95% CI: 0.59 to 0.68), respectively. After 6 months of ART, virological suppression was 76.6% (95% CI: 75.8% to 77.5%) in CBAS patients versus 72% (95% CI: 71.3% to 72.5%) in non-CBAS patients (P < 0.0001), adjusted odds ratio was 1.22 (95% CI: 1.14 to 1.30). Improvement in virological suppression occurred progressively for longer durations of ART [adjusted odds ratio was 2.66 (95% CI: 1.61 to 4.40) by 5 years].

CONCLUSIONS

Patients receiving CBAS had considerably better ART outcomes. Further scale-up of these programs should be considered in low-income settings.

The United States government's response to HIV/AIDS today: 'test and treat' as prevention

Three decades into the HIV/AIDS epidemic, HIV prevention programs have been only partially effective. New prevention tools are providing new reasons for optimism. Effective use of these new tools, including the 'test-and-treat' strategy, will require considerable effort to assure that their potential for prevention is fully realized. Challenges with the test-and-treat strategy are global ones, and include retention in care and adherence to treatment. Worldwide, those with HIV infection become less adherent to antiretroviral therapy over time. Many factors contributing to retention in care and adherence to therapy differ among countries and regions of the world. HIV-infected persons receiving treatment in sub-Saharan Africa have been reported to have higher adherence rates than those receiving treatment on the North American continent; higher health literacy and perception of treatment as a social obligation may enhance adherence to treatment and retention in care. The HIV test-and-treat strategy offers a major step forward when combined with other prevention efforts; we need to consider what additional steps are needed to deliver on the promise of prevention through treatment.

Impact of individual-level social capital on quality of life among AIDS patients in China

Background

With growing recognition of the social determinants of health, social capital is an increasingly important construct in international health. However, the application of social capital discourse in response to HIV infection remains preliminary. The aim of this study was to assess the impact of social capital on quality of life (QoL) among adult patients with acquired immune deficiency syndrome (AIDS).

Methods

A convenient sample of 283 patients receiving antiretroviral treatment (ART) was investigated in Anhui province, China. QoL data were collected using the Medical Outcomes Study HIV Survey (MOS-HIV) questionnaire. Social capital was measured using a self-developed questionnaire. Logistic regression models were used to explore associations between social capital and QoL.

Results

The study sample had a mean physical health summary (PHS) score of 50.13±9.90 and a mean mental health summary (MHS) score of 41.64±11.68. Cronbach's α coefficients of the five multi-item scales of social capital ranged from 0.44 to 0.79. When other variables were controlled for, lower individual levels of reciprocity and trust were associated with a greater likelihood of having a poor PHS score (odds ratio [OR] = 2.02) or PHS score (OR = 6.90). Additionally, the factors of social support and social networks and ties were associated positively with MHS score (OR = 2.30, OR = 4.17, respectively).

Conclusions

This is the first report to explore the effects of social capital on QoL of AIDS patients in China. The results indicate that social capital is a promising avenue for developing strategies to improve the QoL of AIDS patients in China, suggesting that the contribution of social capital should be fully exploited, especially with enhancement of QoL through social participation. Social capital development policy may be worthy of consideration.

How treatment partners help: social analysis of an African adherence support intervention

Treatment partnering is an adherence intervention developed in sub-Saharan Africa. This paper describes the additional social functions that treatment partners serve and shows how these functions contribute to health and survival for patients with HIV/AIDS. Ninety-eight minimally structured interviews were conducted with twenty pairs of adult HIV/AIDS patients (N = 20) and treatment partners (N = 20) treated at a public HIV-care setting in Tanzania. Four social functions were identified using inductive, category construction and interpretive methods of analysis: (1) encouraging disclosure; (2) combating stigma; (3) restoring hope; and (4) reducing social difference. These functions work to restore social connections and reverse the isolating effects of HIV/AIDS, strengthening access to essential community safety nets. Besides encouraging ARV adherence, treatment partners contribute to the social health of patients. Social health as well as HIV treatment success is essential to survival for persons living with HIV/AIDS in sub-Saharan Africa.

Attitudes and practices towards HAART among people living with HIV/AIDS in a resource-limited setting in northern Burkina Faso

OBJECTIVES

To assess the perception of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), and attitudes and practices towards highly active antiretroviral treatment (HAART) among patients living in a resource-poor region of northern Burkina Faso, where HAART has only become available in recent years.

STUDY DESIGN

A clinic-based cross-sectional survey of 306 patients taking HAART and 106 patients not yet on HAART.

METHODS

Face-to-face interview with a structured questionnaire at the clinic or at participants' homes.

RESULTS

Most patients were illiterate, but overall, they had adequate knowledge and positive attitudes towards HAART, and self-reported that their adherence was good. However, AIDS carried a psychological burden, as 27% of respondents were concerned that others might discover they were on HAART. The majority of respondents expressed concerns about transmitting HIV to others, but only 22% had disclosed their HIV status to their partners, and condom use was suboptimal. Approximately one-third of participants in the HAART group reported that they could no longer work in the same way as before they had AIDS. Multivariate logistic regression found that education and living with someone were positively associated with a favourable functioning status, and distance from clinic and lack of general support from family or friends were negatively associated with a favourable functioning status.

CONCLUSIONS

HAART was well accepted in this resource-poor region. Community education and supportive approaches may be critical for an effective preventive programme.

Building adherence-competent communities: factors promoting children's adherence to anti-retroviral HIV/AIDS treatment in rural Zimbabwe

Given relatively high levels of adherence to HIV treatment in Africa, we explore factors facilitating children's adherence, despite poverty, social disruption and limited health infrastructure. Using interviews with 25 nurses and 40 guardians in Zimbabwe, we develop our conceptualisation of an ‘adherence competent community’, showing how members of five networks (children, guardians, community members, health workers and NGOs) have taken advantage of the gradual public normalisation of HIV/AIDS and improved drug and service availability to construct new norms of solidarity with HIV and AIDS sufferers, recognition of HIV-infected children's social worth, an ethic of care/assistance and a supporting atmosphere of enablement/empowerment.

Social capital and women's reduced vulnerability to HIV infection in rural Zimbabwe

Social capital—especially through its “network” dimension (high levels of participation in local community groups)—is thought to be an important determinant of health in many contexts. We investigate its effect on HIV prevention, using prospective data from a general population cohort in eastern Zimbabwe spanning a period of extensive behavior change (1998–2003). Almost half of the initially uninfected women interviewed were members of at least one community group. In an analysis of 88 communities, individuals with higher levels of community group participation had lower incidence of new HIV infections and more of them had adopted safer behaviors, although these effects were largely accounted for by differences in socio-demographic composition. Individual women in community groups had lower HIV incidence and more extensive behavior change, even after controlling for confounding factors. Community group membership was not associated with lower HIV incidence in men, possibly refecting a propensity among men to participate in groups that allow them to develop and demonstrate their masculine identities—often at the expense of their health. Support for women's community groups could be an effective HIV prevention strategy in countries with large-scale HIV epidemics.

Treatment of hypertension in rural Cambodia: results from a 6-year programme

This study was aimed to describe the outcomes of a hypertension treatment programme in two outpatient clinics in Cambodia. We determined proportions of patients who met the optimal targets for blood pressure (BP) control and assessed the evolution of mean systolic and diastolic BP (SBP/DBP) over time. Multivariate analyses were used to identify predictors of BP decrease and risk factors for LTFU. A total of 2858 patients were enrolled between March 2002 and June 2008 of whom 69.2% were female, 30.5% were aged ≥64 years and 32.6% were diabetic. The median follow-up time was 600 days. By the end of 2008, 1642 (57.4%) were alive-in-care, 8 (0.3%) had died and 1208 (42.3%) were lost to follow-up. On admission, mean SBP and DBP were 162 and 94 mm Hg, respectively. Among the patients treated, a significant SBP reduction of 26.8 mm Hg (95% CI: 28.4-25.3) was observed at 6 months. Overall, 36.5% of patients reached the BP targets at 24 months. The number of young adults, non-overweight patients and non-diabetics reaching the BP targets was more. Older age (>64 years), uncontrolled DBP (≥90 mm Hg) on last consultation and coming late for the last consultation were associated with LTFU, whereas non-diabetic patients were 1.5 times more likely to default than diabetics (95% CI: 1.3-1.7). Although the definite magnitude of the BP decrease due to antihypertension medication over time cannot be assessed definitely without a control group, our results suggest that BP reduction can be obtained with essential hypertension treatment in a large-scale programme in a resource-limited setting.
