Abstract
BACKGROUND The effectiveness of community-based primary health care (CBPHC) interventions in low- and middle-income countries (LMICs), especially for maternal, neonatal and child health, is well established. However, there has not been a systematic review of the literature on the effectiveness of CBPHC on HIV outcomes derived from rigorous assessments of primary studies. Using peer-reviewed studies of randomized interventions or those containing a specified control group and directly measuring clinical HIV outcomes, we provide evidence for the effectiveness of CBPHC on HIV outcomes for mothers and children in low- and middle-income countries (LMICs). METHODS Eligibility criteria included studies assessing the effectiveness of community-based HIV interventions with or without a facility-based component, or multiple integrated projects, with outcome measures defining an aspect of HIV health status such as the utilization of prevention or health care services, nutritional status, serious morbidity (including clinical measures of HIV progression) or mortality of children aged five or younger and pregnant women. Articles published through June 3, 2020 were identified by searching four databases. The type of community-based projects implemented, the implementors, and the implementation strategies of each program were identified and the impact on HIV-related outcomes assessed. RESULTS The search yielded 10 537 articles; 4881 underwent title and abstract screening after removing duplicates. Of these, 117 studies qualified for full-text screening; only 22 were included in the final analysis. Most studies showed that community-based interventions improved HIV prevention and treatment outcomes compared to facility-based approaches alone. Each study had at least one statistically significant HIV-related outcome; the non-significant outcomes found in six of the 22 studies were mostly not related to HIV programming. Most interventions were implemented by community health workers; other implementers were government workers, community members, or research staff. Strategies used included peer-to-peer education, psychosocial support, training of community champions, community-based follow-up care, home-based care, and integrated care. CONCLUSIONS CBPHC strategies are effective in improving population-based, HIV-related health outcomes for mothers and children, especially in combination with facility-based approaches. However, there is a need to assess the scalability of such interventions and integrate them into existing health systems to assess their impact on the HIV pandemic in more routine settings.

Recruitment of Youth Living With HIV to Optimize Adherence and Virologic Suppression: Testing the Design of Technology-Based Community Health Nursing to Improve Antiretroviral Therapy (ART) Clinical Trials. JMIR Res Protoc 2020; 9:e23480. [PMID: 33306036 PMCID: PMC7762679 DOI: 10.2196/23480] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Revised: 09/24/2020] [Accepted: 09/29/2020] [Indexed: 01/26/2023] Open
Abstract
Background Despite advances in HIV diagnosis and treatment, adolescents and young adults 12-25 years old have high HIV incidence, poor engagement and retention in treatment, and low rates of adherence and virologic suppression when compared to their older counterparts. HIV has emerged as a chronic disease for which antiretroviral therapy (ART) adherence is critical for virologic suppression and long-term survival. Virologic suppression has been elusive for many youth with HIV (YHIV). Novel strategies designed to facilitate health care systems’ support for YHIV between medical visits are essential for improving ART adherence, virologic suppression, and long-term survival. Objective The aim of this study is to compare the effectiveness of a technology-enhanced community health nursing intervention (TECH2CHECK) to a standard of care (SOC) control group for improving ART adherence and subsequent viral suppression using a randomized trial design. The objectives are to assess the feasibility, acceptability, and cost-effectiveness of TECH2CHECK as compared to SOC for management of HIV in the outpatient setting and to examine the sustainability of self-care behavior, adherence, and virologic suppression among youth following the intervention period. Methods We will recruit 120 adherence-challenged YHIV being followed at clinics specializing in HIV care in the Baltimore-Washington metropolitan area and in Jacksonville. Eligible participants complete an audio, computer-assisted self-interview and are randomized to either TECH2CHECK intervention or the SOC (60 participants in each arm). The primary outcome of interest is virologic suppression (viral load <20 copies/mL) and improved treatment adherence. Participants in the intervention arm receive community health nursing visits at 2 weeks, 6 weeks, 10 weeks, 14 weeks, and 26 weeks. The intervention arm also receives SMS messaging comprising daily adherence and appointment reminders and positive reinforcement for medication adherence daily for 2 weeks, on alternate days for 2 weeks, thrice weekly for 1 month, weekly for 3 months, and every 2 weeks for the rest of the study duration. The control group receives appointment reminders and SOC per clinic protocol. Exploratory analysis will be conducted to determine differences in medication adherence and virologic suppression in the 2 arms and to assess cost-effectiveness and study feasibility and acceptability. Results In the first 23 months of the study (July 2018-April 2020), 56 (55%) of 102 eligible patients were enrolled and randomized. At present, participating youths are primarily African American (53/56, 95%), male (37/56, 66%), and ≥18 years old (53/56, 95%). Follow-up study visits, as required per the protocol, have been completed by 77% (43/56), 94% (45/48), 95% (37/39), 96% (24/25), and 100% (10/10) of participants at the 1-month, 3-month, 6-month, 12-month, and 18-month follow-ups, respectively. Conclusions Preliminary accrual and retention data suggest that TECH2CHECK is feasible and acceptable.

Abstract
BACKGROUND There are significant number of patients who are on highly active antiretroviral therapy (HAART) not virally suppressed, which is a huge clinical challenge. Social support as a non-pharmacological factor, which may influence the viral suppression, is less studied and has equivocal results. The aim of this study was to investigate the association between social support and viral load (VL) in adults on HAART. METHODS This was an analytical cross-sectional study. Using a structured questionnaire, 380 adults (≥ 18 years) on HAART for ≥ 6 months were recruited between November 2018 and February 2019 from Witbank hospital and surrounding clinics. Multivariable logistic regression was carried out. RESULTS The mean age of the participants was 40.5 years (s.d. = 10.3). The majority were females (73%), at least high school educated (84%), unemployed (57%), single (63%) and did not have comorbidity (80%). The vast majority had moderate to high adherence (84%) and moderate to good perceived social support (94%). The viral suppression rate was 87%. Both adherence (p 0.001) and social support (p = 0.017) were significantly associated with VL. However, only adherence was predictive of viral suppression in multivariable analysis. Compared to poorly adherent, moderately (OR = 2.8; 95% CI = 1.32-5.98) and highly (OR = 5.3; 95% CI = 2.41-11.81) adherent participants were more likely to have suppressed VL. CONCLUSION Viral suppression rate was high. Self-reported adherence to HAART was highly predictive of viral suppression, which highlights the importance of assessing and addressing adherence issues at every contact with patients taking HAART. Good social support did not predict viral suppression.

Abstract
Background The advent and widespread use of antiretroviral therapy (ART) has remarkably changed the paradigm of HIV infection, increasing substantially the lifespan and quality of life of people affected. Accordingly and responding to policy makers and international directives, many strategies were put in place in Cameroon to accelerate ART uptake, including the community dispensation of ART through community-based organizations (CBOs). Main body In its strategic plan to curb the burden of HIV/AIDS and as part of accelerating and reinforcing the provision of ART to all people living with HIV (PLWH), Cameroon opted for different strategies including the dispensation of ART in the community through well identified and tutored CBOs. Actually, financing of ART in Cameroon is mainly the conjugation of resources from the Government and its technical and financial partners, basically the Global Funds supplemented by supports from the Unitaid initiative which allows PLWH residing in Cameroon to benefit from continuous ART without spending a dime. However, this external funding will end-up by 2020. Therefore, there is urgent need to think of alternative and efficient strategies to sustain the fight against HIV/AIDS in Cameroon, especially the provision of ART to patients through community dispensation. Some studies carried out in sub-Saharan African countries have shown that mutual health insurance seems to be a solution with great potential to improve access to quality care, mobilize the necessary funds, improve efficiency of the health sector, and promote dialogue and democratic governance in the health sector along with social and institutional development of the society. Conclusions The pooling of associations of PLWH in Cameroon and other countries of sub-Saharan Africa in line with the Bamako Initiative constitutes a promising strategy that would undoubtedly help to offset the withdrawal of funding from external sources, and allow an appropriation of the fight against HIV/AIDS by those concerned at the first place. Nevertheless, other lines of research of financing could be explored in the economic sector.

Abstract
BACKGROUND Children and adolescents have poorer HIV treatment outcomes than adults. We aimed to assess the effect of community-based support for caregivers of HIV-infected children and adolescents, who are key mediators to children engaging with care, on treatment outcomes. METHODS In this open-label, randomised contolled trial, we recruited children aged 6-15 years with newly-diagnosed HIV attending primary health-care clinics in Harare, Zimbabwe. Children were randomly assigned to receive decentralised primary health-care clinic-based HIV care (control group), according to national guidelines for 18 months, or decentralised care plus structured support visits by trained community health workers (intervention group) according to national guidelines for 18 months. Primary outcomes were the proportion of participants who died or had an HIV viral load of 400 copies per mL or higher at 12 months after antiretroviral therapy (ART) initiation (among those who started ART within 6 months of enrolment); and the proportion who missed two or more scheduled clinic visits by 18 months post-enrolment (among all participants). Analyses were complete-case, modified-intention-to-treat. This trial is registered with the Pan African Clinical Trials Registry, number PACTR201212000442288. FINDINGS Between January, 2013, and January, 2015, 470 participants tested HIV-positive at seven study primary health-care clinics and were screened for eligibility. Of the 334 eligible children and adolescents, 166 were randomly assigned to the intervention group and 168 to the control group. The median age of participants was 11 years (IQR 8-13) and 178 (53%) were girls. Among the 238 participants who started ART within 6 months of enrolment, the proportion who died or had a viral load of 400 copies/mL or higher at 12 months post-ART initiation was significantly lower in the intervention group than in the control group (31 [33%] of 94 participants vs 42 [49%] of 86 participants, respectively, adjusted odds ratio [aOR] 0·46, 95% CI 0·23-0·89; p=0·02). The proportion of children missing two or more scheduled visits was similar in the intervention group and control group (27 [17%] of 155 vs 30 [18%] of 165, aOR 0·92, 95% CI 0·49-1·74; p=0·79). One participant withdrew from the trial 240 days after enrolment and 12 died during follow-up (five in the intervention group; seven in the control group). INTERPRETATION Community-based support for caregivers has high potential for scalability and could have a substantial effect on HIV virological suppression in children and adolescents, a group with disproportionately poor treatment outcomes.

Abstract
Little is known about the effect of community versus health facility-based interventions to improve and sustain antiretroviral therapy (ART) adherence, virologic suppression, and retention in care among HIV-infected individuals in low- and middle-income countries (LMICs). We systematically searched four electronic databases for all available randomized controlled trials (RCTs) and comparative cohort studies in LMICs comparing community versus health facility-based interventions. Relative risks (RRs) for pre-defined adherence, treatment engagement (linkage and retention in care), and relevant clinical outcomes were pooled using random effect models. Eleven cohort studies and eleven RCTs (N = 97,657) were included. Meta-analysis of the included RCTs comparing community- versus health facility-based interventions found comparable outcomes in terms of ART adherence (RR = 1.02, 95 % CI 0.99 to 1.04), virologic suppression (RR = 1.00, 95 % CI 0.98 to 1.03), and all-cause mortality (RR = 0.93, 95 % CI 0.73 to 1.18). The result of pooled analysis from the RCTs (RR = 1.03, 95 % CI 1.01 to 1.06) and cohort studies (RR = 1.09, 95 % CI 1.03 to 1.15) found that participants assigned to community-based interventions had statistically significantly higher rates of treatment engagement. Two studies found community-based ART delivery model either cost-saving or cost-effective. Community- versus facility-based models of ART delivery resulted in at least comparable outcomes for clinically stable HIV-infected patients on treatment in LMICs and are likely to be cost-effective.

Abstract
Community health workers (CHWs) can help to redress the shortages of health human resources needed to scale up antiretroviral treatment (ART). However, the selection of CHWs could influence the effectiveness of a CHW programme. The purpose of this observational study was to assess whether sociodemographic characteristics and geographic proximity to patients of volunteer CHWs were predictors of clinical outcomes in a community-based ART (CBART) programme in Kabarole, Uganda. Data from CHW surveys for 41 CHWs and clinic charts for 185 patients in the CBART programme were analysed using multivariable logistic and Cox regression models. Time to travel to patients was the only statistically significant characteristic of CHWs associated with ART outcomes. Patients whose CHWs had to travel one or more hours had a 71% lower odds of virologic suppression (adjusted OR = 0.29, 95% CI = 0.13-0.65, p = .002) and a 4.52 times higher mortality hazard rate (adjusted HR = 4.52, 95% CI = 1.20-17.09, p = .026) compared to patients whose CHWs had to travel less than one hour. The findings show that the sociodemographic characteristics of CHWs were not as important as the geographic distance they had to travel to patients.

Abstract
BACKGROUND/PURPOSE This study aimed to evaluate the association between highly active antiretroviral therapy (HAART) adherence and development of Kaposi's sarcoma (KS) in human immunodeficiency virus (HIV)/AIDS patients. METHODS We conducted a retrospective nested case-control study of 165 participants (33 cases and 132 controls) receiving HAART care at Maseno Hospital, Kenya, from January 2005 to October 2013. Cases were HIV-positive adults with KS, who were matched with controls in a ratio of 1:4 based on age (±5 years of each case), sex, and KS diagnosis date. Perfect adherence to HAART was assessed on every clinic visit by patients' self-reporting and pill counts. Chi-square tests were performed to compare socioeconomic and clinical statuses between cases and controls. A conditional logistic regression was used to assess the effects of perfect adherence to HAART, the latest CD4 count, education level, distance to health-care facility, initial World Health Organization stage, and number of regular sexual partners on the development of KS. RESULTS Only 63.6% participants reported perfect adherence, and the control group had a significantly higher percentage of perfect adherence (75.0%) than did cases (18.2%). After adjustment for potential imbalances in the baseline and clinical characteristics, patients with imperfect HAART adherence had 20-times greater risk of developing KS than patients with perfect HAART adherence [hazard ratios: 21.0, 95% confidence interval: 4.2-105.1]. Patients with low latest CD4 count (≤350 cells/mm3) had a seven-times greater risk of developing KS than did their counterparts (HRs: 7.1, 95% CI: 1.4-36.2). CONCLUSION Imperfect HAART adherence and low latest CD4 count are significantly associated with KS development.
