Participation in adherence clubs and on-time drug pickup among HIV-infected adults in Zambia: A matched-pair cluster randomized trial. PLoS Med 2020; 17:e1003116.

Abstract
BACKGROUND Current models of HIV service delivery, with frequent facility visits, have led to facility congestion, patient and healthcare provider dissatisfaction, and suboptimal quality of services and retention in care. The Zambian urban adherence club (AC) is a health service innovation designed to improve on-time drug pickup and retention in HIV care through off-hours facility access and pharmacist-led group drug distribution. Similar models of differentiated service delivery (DSD) have shown promise in South Africa, but observational analyses of these models are prone to bias and confounding. We sought to evaluate the effectiveness and implementation of ACs in Zambia using a more rigorous study design. METHODS AND FINDINGS Using a matched-pair cluster randomized study design (ClinicalTrials.gov: NCT02776254), 10 clinics were randomized to intervention (5 clinics) or control (5 clinics). At each clinic, between May 19 and October 27, 2016, a systematic random sample was assessed for eligibility (HIV+, age ≥ 14 years, on ART >6 months, not acutely ill, CD4 count not <200 cells/mm3) and willingness to participate in an AC. Clinical and antiretroviral drug pickup data were obtained through the existing electronic medical record. AC meeting attendance data were collected at intervention facilities prospectively through October 28, 2017. The primary outcome was time to first late drug pickup (>7 days late). Intervention effect was estimated using unadjusted Kaplan-Meier survival curves and a Cox proportional hazards model to derive an adjusted hazard ratio (aHR). Medication possession ratio (MPR) and implementation outcomes (adoption, acceptability, appropriateness, feasibility, and fidelity) were additionally evaluated as secondary outcomes. Baseline characteristics were similar between 571 intervention and 489 control participants with respect to median age (42 versus 41 years), sex (62% versus 66% female), median time since ART initiation (4.8 versus 5.0 years), median CD4 count at study enrollment (506 versus 533 cells/mm3), and baseline retention (53% versus 55% with at least 1 late drug pickup in previous 12 months). The rate of late drug pickup was lower in intervention participants compared to control participants (aHR 0.26, 95% CI 0.15-0.45, p < 0.001). Median MPR was 100% in intervention participants compared to 96% in control participants (p < 0.001). Although 18% (683/3,734) of AC group meeting visits were missed, on-time drug pickup (within 7 days) still occurred in 51% (350/683) of these missed visits through alternate means (use of buddy pickup or early return to the facility). Qualitative evaluation suggests that the intervention was acceptable to both patients and providers. While patients embraced the convenience and patient-centeredness of the model, preference for traditional adherence counseling and need for greater human resources influenced intervention appropriateness and feasibility from the provider perspective. The main limitations of this study were the small number of clusters, lack of viral load data, and relatively short follow-up period. CONCLUSIONS ACs were found to be an effective model of service delivery for reducing late ART drug pickup among HIV-infected adults in Zambia. Drug pickup outside of group meetings was relatively common and underscores the need for DSD models to be flexible and patient-centered if they are to be effective.

The Role of Patient-Provider Communication in Engagement and Re-engagement in HIV Treatment in Bamako, Mali: A Qualitative Study. JOURNAL OF HEALTH COMMUNICATION 2017; 23:129-143.

Abstract
Mounting evidence in sub-Saharan Africa suggests poor patient-provider communication (PPC) negatively impacts patient engagement (retention in care and adherence to medication) in antiretroviral therapy (ART) programs. In Bamako, Mali, where 36% of ART patients are lost to follow-up within 12 months of initiating treatment, we aimed to define features of positive PPC according to patient values and explore the mechanisms by which these features may sustain engagement and re-engagement according to patient and provider experiences. We conducted 33 in-depth interviews and 7 focus groups with 69 patients and 17 providers in five ART clinics. Regarding sustaining engagement, participants highlighted "establishing rapport" as a foundational feature of effective PPC, but also described how "responding to emotional needs", "eliciting patient conflicts and perspective" and "partnering to mitigate conflicts" functioned to address barriers to engagement and increase connectedness to care. Patients who had disengaged felt that "communicating reacceptance" may have prompted them re-engage sooner and that tailored "partnering to mitigate conflicts" would be more effective in sustaining re-engagement than the standard adherence education providers typically offer. Optimizing provider skills related to these key PPC features may help maximize ART patient engagement, ultimately improving health outcomes and decreasing HIV transmission in sub-Saharan Africa.

Retention Throughout the HIV Care and Treatment Cascade: From Diagnosis to Antiretroviral Treatment of Adults and Children Living with HIV-Haiti, 1985-2015. Am J Trop Med Hyg 2017; 97:57-70. [PMID: 29064357 PMCID: PMC5676635 DOI: 10.4269/ajtmh.17-0116] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/23/2022] Open
Abstract
Monitoring retention of people living with HIV (PLHIV) in the HIV care and treatment cascade is essential to guide program strategy and evaluate progress toward globally-endorsed 90–90–90 targets (i.e., 90% of PLHIV diagnosed, 81% on sustained antiretroviral therapy (ART), and 73% virally suppressed). We describe national retention from diagnosis throughout the cascade for patients receiving HIV services in Haiti during 1985–2015, with a focus on those receiving HIV services during 2008–2015. Among the 266,256 newly diagnosed PLHIV during 1985–2015, 49% were linked-to-care, 30% started ART, and 18% were retained on ART by the time of database closure. Similarly, among the 192,187 newly diagnosed HIV-positive patients during 2008–2015, 50% were linked to care, 31% started ART, and 19% were retained on ART by the time of database closure. Most patients (90–92%) at all cascade steps were adults (≥ 15 years old), among whom the majority (60–61%) were female. During 2008–2015, outcomes varied significantly across 42 administrative districts (arrondissements) of residence; cumulative linkage-to-care ranged from 23% to 69%, cumulative ART initiation among care enrollees ranged from 2% to 80%, and cumulative ART retention among ART enrollees ranged from 30% to 88%. Compared with adults, children had lower cumulative incidence of ART initiation among care enrollees (64% versus 47%) and lower cumulative retention among ART enrollees (64% versus 50%). Cumulative linkage-to-care was low and should be prioritized for improvement. Variations in outcomes by arrondissement and between adults and children require further investigation and programmatic response.

Abstract
As human immunodeficiency virus (HIV) treatment programs expand in Africa, delivery systems must be strengthened to support patient retention. Clinic characteristics may affect retention, but a relationship between clinic flow and attrition is not established. This project characterized HIV patient experience and flow in an urban Kenyan clinic to understand how these may affect retention. We used Toyota's lean manufacturing principles to guide data collection and analysis. Clinic flow was evaluated using value stream mapping and time and motion techniques. Clinic register data were analyzed. Two focus group discussions were held to characterize HIV patient experience. Results were shared with clinic staff. Wait times in the clinic were highly variable. We identified four main barriers to patient flow: inconsistent patient arrivals, inconsistent staffing, filing system defects, and serving patients out of order. Focus group participants explained how clinic operations affected their ability to engage in care. Clinic staff were eager to discuss the problems identified and identified numerous low-cost potential solutions. Lean manufacturing methodologies can guide efficiency interventions in low-resource healthcare settings. Using lean techniques, we identified bottlenecks to clinic flow and low-cost solutions to improve wait times. Improving flow may result in increased patient satisfaction and retention.

Abstract
BACKGROUND During 2004-2013 in Mozambique, 455,600 HIV-positive adults (≥15 years old) initiated antiretroviral therapy (ART). We evaluated trends in patient characteristics and outcomes during 2004-2013, outcomes of universal treatment for pregnant women (Option B+) implemented since 2013, and effect on outcomes of distributing ART to stable patients through Community ART Support Groups (CASG) since 2010. METHODS Data for 306,335 adults starting ART during 2004-2013 at 170 ART facilities were analyzed. Mortality and loss to follow-up (LTFU) were estimated using competing risks models. Outcome determinants were estimated using proportional hazards models, including CASG participation as a time-varying covariate. RESULTS Compared with ART enrollees in 2004, enrollees in 2013 were more commonly female (55% vs. 73%), more commonly pregnant if female (<1% vs. 30%), and had a higher median baseline CD4 count (139 vs. 235/μL). During 2004-2013, observed 6-month mortality declined from 7% to 2% but LTFU increased from 24% to 30%. Pregnant women starting ART with CD4 count >350/μL and WHO stage I/II under Option B+ guidelines in 2013 had low 6-month mortality (0.1%) but high 6-month LTFU (38%). During 2010-2013, 6766 patients joined CASGs. In multivariable analysis, compared with nonparticipation in CASG, CASG participation was associated with 35% lower LTFU but similar mortality. CONCLUSIONS Initiation of ART at earlier disease stages in later calendar years might explain observed declines in mortality. Retention interventions are needed to address trends of increasing LTFU overall and the high LTFU among Option B+ pregnant women specifically. Further expansion of CASG could help reduce LTFU.

Abstract
BACKGROUND The threshold of 2.3 skilled health workers per 1,000 population, published in the World Health Report in 2006, has galvanized resources and efforts to attain high coverage of skilled birth attendance. With the inception of the Sustainable Development Goals (SDGs), a new threshold of 4.45 doctors, nurses, and midwives per 1,000 population has been identified. This SDG index threshold indicates the minimum density to respond to the needs of health workers to deliver a much broader range of health services, such as management of non-communicable diseases to meet the targets under Goal 3: Ensure healthy lives and promote well-being for all people of all ages. In the United Republic of Tanzania, the density of skilled health workers in 2012 was 0.5 per 1,000 population, which more than doubled from 0.2 per 1,000 in 2002. However, this showed that Tanzania still faced a critical shortage of skilled health workers. While training, deployment, and retention are important, motivation is also necessary for all health workers, particularly those who serve in rural areas. This study measured the motivation of health workers who were posted at government-run rural primary health facilities. OBJECTIVES We sought to measure three aspects of motivation-Management, Performance, and Individual Aspects-among health workers deployed in rural primary level government health facilities. In addition, we also sought to identify the job-related attributes associated with each of these three aspects. Two regions in Tanzania were selected for our research. In each region, we further selected two districts in which we carried out our investigation. The two regions were Lindi, where we carried out our study in the Nachingwea District and the Ruangwa District, and Mbeya, within which the Mbarali and Rungwe Districts were selected for research. All four districts are considered rural. METHODS This cross-sectional study was conducted by administering a two-part questionnaire in the Kiswahili language. The first part was administered by a researcher, and contained questions for gaining socio-demographic and occupational information. The second part was a self-administered questionnaire that contained 45 statements used to measure three aspects of motivation among health workers. For analyzing the data, we performed multivariate regression analysis in order to evaluate the simultaneous effects of factors on the outcomes of the motivation scores in the three areas of Management, Performance, and Individual Aspects. RESULTS Motivation was associated with marital status (p = 0.009), having a job description (p<0.001), and number of years in the current profession (<1 year: p = 0.043, >7 years: p = 0.042) for Management Aspects; having a job description (p<0.001) for Performance Aspects; and salary scale (p = 0.029) for Individual Aspects. CONCLUSION Having a clear job description motivates health workers. The existing Open Performance Review and Appraisal System, of which job descriptions are the foundation, needs to be institutionalized in order to effectively manage the health workforce in resource-limited settings.

Abstract
Though great progress has been realized over the last decade in extending HIV
prevention, care and treatment in some of the least resourced settings of the
world, a substantial gap remains between what we know works and what we are
actually achieving in HIV programs. To address this, leaders have called for the
adoption of an implementation science framework to improve the efficiency and
effectiveness of HIV programs. Implementation science (IS) is a
multidisciplinary scientific field that seeks generalizable knowledge about the
magnitude of, determinants of and strategies to close the gap between evidence
and routine practice for health in real-world settings. We propose an IS
approach that is iterative in nature and composed of four major components: 1)
Identifying Bottlenecks and Gaps, 2) Developing and Implementing Strategies, 3)
Measuring Effectiveness and Efficiency, and 4) Utilizing Results. With this
framework, IS initiatives draw from a variety of disciplines including
qualitative and quantitative methodologies in order to develop new approaches
responsive to the complexities of real world program delivery. In order to
remain useful for the changing programmatic landscape, IS research should factor
in relevant timeframes and engage the multi-sectoral community of stakeholders,
including community members, health care teams, program managers, researchers
and policy makers, to facilitate the development of programs, practices and
polices that lead to a more effective and efficient global AIDS response. The
approach presented here is a synthesis of approaches and is a useful model to
address IS-related questions for HIV prevention, care and treatment programs.
This approach, however, is not a panacea, and we will continue to learn new ways
of thinking as we move forward to close the implementation gap.

Abstract
BACKGROUND The traditional HIV treatment cascade has been noted to have limitations. A proposed comprehensive HIV care cascade that uses cohort methodology offers additional information as it accounts for all patients. Using data from 4 countries, we compare patient outcomes using both approaches. METHODS Data from 390,603 HIV-infected adults (>15 years) enrolled at 217 facilities in Kenya, Mozambique, Rwanda, and Tanzania from 2005 to 2011 were included. Outcomes of all patients at 3, 6, and 12 months after enrollment were categorized as optimal, suboptimal, or poor. Optimal outcomes included retention in care, antiretroviral therapy (ART) initiation, and documented transfer. Suboptimal outcomes included retention in care without ART initiation among eligible patients or those without eligibility data. Poor outcomes included loss to follow-up and death. RESULTS The comprehensive HIV care cascade demonstrated that at 3, 6 and 12 months, 58%, 51%, and 49% of patients had optimal outcomes; 22%, 12%, and 7% had suboptimal outcomes, and 20%, 37% and 44% had poor outcomes. Of all patients enrolled in care, 56% were retained in care at 12 months after enrollment. In comparison, the traditional HIV treatment cascade found 89% of patients enrolled in HIV care were assessed for ART eligibility, of whom 48% were determined to be ART-eligible with 70% initiating ART, and 78% of those initiated on ART retained at 12 months. CONCLUSIONS The comprehensive HIV care cascade follows outcomes of all patients, including pre-ART patients, who enroll in HIV care over time and uses quality of care parameters for categorizing outcomes. The comprehensive HIV care cascade provides complementary information to that of the traditional HIV treatment cascade and is a valuable tool for monitoring HIV program performance.

Abstract
BACKGROUND We previously published systematic reviews of retention in care after antiretroviral therapy initiation among general adult populations in sub-Saharan Africa. We estimated 36-month retention at 73% for publications from 2007 to 2010. This report extends the review to cover 2008-2013 and expands it to all low- and middle-income countries. METHODS We searched PubMed, Embase, Cochrane Register, and ISI Web of Science from January 1, 2008, to December 31, 2013, and abstracts from AIDS and IAS from 2008-2013. We estimated retention across cohorts using simple averages and interpolated missing times through the last time reported. We estimated all-cause attrition (death, loss to follow-up) for patients receiving first-line antiretroviral therapy in routine settings in low- and middle-income countries. RESULTS We found 123 articles and abstracts reporting retention for 154 patient cohorts and 1,554,773 patients in 42 countries. Overall, 43% of all patients not retained were known to have died. Unweighted averages of reported retention were 78%, 71%, and 69% at 12, 24, and 36 months, after treatment initiation, respectively. We estimated 36-month retention at 65% in Africa, 80% in Asia, and 64% in Latin America and the Caribbean. From lifetable analysis, we estimated retention at 12, 24, 36, 48, and 60 months at 83%, 74%, 68%, 64%, and 60%, respectively. CONCLUSIONS Retention at 36 months on treatment averages 65%-70%. There are several important gaps in the evidence base, which could be filled by further research, especially in terms of geographic coverage and duration of follow-up.

Vermund SH, Blevins M, Moon TD, José E, Moiane L, Tique JA, Sidat M, Ciampa PJ, Shepherd BE, Vaz LME. Poor clinical outcomes for HIV infected children on antiretroviral therapy in rural Mozambique: need for program quality improvement and community engagement. PLoS One 2014; 9:e110116. [PMID: 25330113 PMCID: PMC4203761 DOI: 10.1371/journal.pone.0110116] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2013] [Accepted: 09/16/2014] [Indexed: 12/15/2022] Open
Abstract
INTRODUCTION Residents of Zambézia Province, Mozambique live from rural subsistence farming and fishing. The 2009 provincial HIV prevalence for adults 15-49 years was 12.6%, higher among women (15.3%) than men (8.9%). We reviewed clinical data to assess outcomes for HIV-infected children on combination antiretroviral therapy (cART) in a highly resource-limited setting. METHODS We studied rates of 2-year mortality and loss to follow-up (LTFU) for children <15 years of age initiating cART between June 2006-July 2011 in 10 rural districts. National guidelines define LTFU as >60 days following last-scheduled medication pickup. Kaplan-Meier estimates to compute mortality assumed non-informative censoring. Cumulative LTFU incidence calculations treated death as a competing risk. RESULTS Of 753 children, 29.0% (95% CI: 24.5, 33.2) were confirmed dead by 2 years and 39.0% (95% CI: 34.8, 42.9) were LTFU with unknown clinical outcomes. The cohort mortality rate was 8.4% (95% CI: 6.3, 10.4) after 90 days on cART and 19.2% (95% CI: 16.0, 22.3) after 365 days. Higher hemoglobin at cART initiation was associated with being alive and on cART at 2 years (alive: 9.3 g/dL vs. dead or LTFU: 8.3-8.4 g/dL, p<0.01). Cotrimoxazole use within 90 days of ART initiation was associated with improved 2-year outcomes Treatment was initiated late (WHO stage III/IV) among 48% of the children with WHO stage recorded in their records. Marked heterogeneity in outcomes by district was noted (p<0.001). CONCLUSIONS We found poor clinical and programmatic outcomes among children taking cART in rural Mozambique. Expanded testing, early infant diagnosis, counseling/support services, case finding, and outreach are insufficiently implemented. Our quality improvement efforts seek to better link pregnancy and HIV services, expand coverage and timeliness of infant diagnosis and treatment, and increase follow-up and adherence.

Sustainability of a community-based anti-retroviral care delivery model - a qualitative research study in Tete, Mozambique. J Int AIDS Soc 2014; 17:18910. [PMID: 25292158 PMCID: PMC4189018 DOI: 10.7448/ias.17.1.18910] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2013] [Revised: 06/19/2014] [Accepted: 08/07/2014] [Indexed: 11/08/2022] Open
Abstract
Introduction To overcome patients’ reported barriers to accessing anti-retroviral therapy (ART), a community-based delivery model was piloted in Tete, Mozambique. Community ART Groups (CAGs) of maximum six patients stable on ART offered cost- and time-saving benefits and mutual psychosocial support, which resulted in better adherence and retention outcomes. To date, Médecins Sans Frontières has coordinated and supported these community-driven activities. Methods To better understand the sustainability of the CAG model, we developed a conceptual framework on sustainability of community-based programmes. This was used to explore the data retrieved from 16 focus group discussions and 24 in-depth interviews with different stakeholder groups involved in the CAG model and to identify factors influencing the sustainability of the CAG model. Results We report the findings according to the framework's five components. (1) The CAG model was designed to overcome patients’ barriers to ART and was built on a concept of self-management and patient empowerment to reach effective results. (2) Despite the progressive Ministry of Health (MoH) involvement, the daily management of the model is still strongly dependent on external resources, especially the need for a regulatory cadre to form and monitor the groups. These additional resources are in contrast to the limited MoH resources available. (3) The model is strongly embedded in the community, with patients taking a more active role in their own healthcare and that of their peers. They are considered as partners in healthcare, which implies a new healthcare approach. (4) There is a growing enabling environment with political will and general acceptance to support the CAG model. (5) However, contextual factors, such as poverty, illiteracy and the weak health system, influence the community-based model and need to be addressed. Conclusions The community embeddedness of the model, together with patient empowerment, high acceptability and progressive MoH involvement strongly favour the future sustainability of the CAG model. The high dependency on external resources for the model's daily management, however, can potentially jeopardize its sustainability. Further reflections are required on possible solutions to solve these challenges, especially in terms of human resources.

Abstract
OBJECTIVE To identify factors associated with antiretroviral therapy (ART) attrition among patients initiating therapy in 2005-2011 at two large, public-sector department-level hospitals, and to inform interventions to improve ART retention. METHODS This retrospective cohort study used data from the iSanté electronic medical record (EMR) system. The study characterized ART attrition levels and explored the patient demographic, clinical, temporal, and service utilization factors associated with ART attrition, using time-to-event analysis methods. RESULTS Among the 2 023 patients in the study, ART attrition on average was 17.0 per 100 person-years (95% confidence interval (CI): 15.8-18.3). In adjusted analyses, risk of ART attrition was up to 89% higher for patients living in distant communes compared to patients living in the same commune as the hospital (hazard ratio: 1.89, 95%CI: 1.54-2.33; P < 0.001). Hospital site, earlier year of ART start, spending less time enrolled in HIV care prior to ART initiation, receiving a non-standard ART regimen, lacking counseling prior to ART initiation, and having a higher body mass index were also associated with attrition risk. CONCLUSIONS The findings suggest quality improvement interventions at the two hospitals, including: enhanced retention support and transportation subsidies for patients accessing care from remote areas; counseling for all patients prior to ART initiation; timely outreach to patients who miss ART pick-ups; "bridging services" for patients transferring care to alternative facilities; routine screening for anticipated interruptions in future ART pick-ups; and medical case review for patients placed on non-standard ART regimens. The findings are also relevant for policymaking on decentralization of ART services in Haiti.

Abstract
Adherence to antiretroviral therapy (ART) is critical for reducing HIV/AIDS morbidity and mortality. Food insecurity (FI) is emerging as an important barrier to adherence to care and treatment recommendations for people living with HIV (PLHIV), but this relationship has not been comprehensively examined. Therefore, we reviewed the literature to explore how FI may impact ART adherence, retention in medical care, and adherence to health care recommendations among PLHIV. We found data to support FI as a critical barrier to adherence to ART and to other health care recommendations among HIV-infected adults, HIV-infected pregnant women and their HIV-exposed infants, and child and adolescent populations of PLHIV. Associations between FI and ART non-adherence were seen in qualitative and quantitative studies. We identified a number of mechanisms to explain how food insecurity and ART non-adherence may be causally linked, including the exacerbation of hunger or ART side effects in the absence of adequate food and competing resource demands. Interventions that address FI may improve adherence to care and treatment recommendations for PLHIV.

Abstract
BACKGROUND Access to antiretroviral therapy (ART) has increased dramatically in resource-limited settings since its introduction a decade ago. However, ART coverage remains low in countries with the highest disease burden, which may be partially explained by poor testing to care linkages. HIV testing service may impact early attrition in the HIV treatment cascade. METHODS A retrospective cohort study was conducted in 18 clinics in central Mozambique using routine patient data and monthly reports. Patients referred from voluntary counseling and testing (VCT) were compared with those referred from prevention of mother-to-child transmission (PMTCT) for 3 outcomes: (1) enrollment at an HIV clinic ≤30 days after testing HIV positive, (2) CD4 test ≤30 days after enrollment, and (3) ART initiation ≤90 days after first CD4 test. RESULTS Patient retention in the HIV care system dropped at each step from HIV testing to ART initiation. Enrollment in HIV care was not significantly different between PMTCT and VCT [risk ratio (RR) = 0.84, 0.72 < RR < 1.02]. Women tested in PMTCT were less likely to have a CD4 test ≤30 days after enrollment when adjusting for age, education level, and marital status (adjusted RR = 0.84, 0.70 < RR < 1.00), and were less likely to initiate ART ≤90 days after their first CD4 test when adjusting for age, education, and marital status (adjusted RR = 0.56, 0.44 < RR < 0.71). CONCLUSIONS Poor linkages between HIV testing and care hamper efforts to improve coverage for HIV care and treatment services. Increased loss to follow-up among women diagnosed in PMTCT relative to VCT is worrisome and merits further qualitative research and programmatic attention.

Adapting a community-based ART delivery model to the patients' needs: a mixed methods research in Tete, Mozambique. BMC Public Health 2014; 14:364. [PMID: 24735550 PMCID: PMC3990026 DOI: 10.1186/1471-2458-14-364] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2013] [Accepted: 04/07/2014] [Indexed: 11/10/2022] Open
Abstract
Background To improve retention in antiretroviral therapy (ART), lessons learned from chronic disease care were applied to HIV care, providing more responsibilities to patients in the care of their chronic disease. In Tete - Mozambique, patients stable on ART participate in the ART provision and peer support through Community ART Groups (CAG). This article analyses the evolution of the CAG-model during its implementation process. Methods A mixed method approach was used, triangulating qualitative and quantitative findings. The qualitative data were collected through semi-structured focus groups discussions and in-depth interviews. An inductive qualitative content analysis was applied to condense and categorise the data in broader themes. Health outcomes, patients’ and groups’ characteristics were calculated using routine collected data. We applied an ‘input – process – output’ pathway to compare the initial planned activities with the current findings. Results Input wise, the counsellors were considered key to form and monitor the groups. In the process, the main modifications found were the progressive adaptations of the daily CAG functioning and the eligibility criteria according to the patients’ needs. Beside the anticipated outputs, i.e. cost and time saving benefits and improved treatment outcomes, the model offered a mutual adherence support and protective environment to the members. The active patient involvement in several health activities in the clinics and the community resulted in a better HIV awareness, decreased stigma, improved health seeking behaviour and better quality of care. Conclusions Over the past four years, the modifications in the CAG-model contributed to a patient empowerment and better treatment outcomes. One of the main outstanding questions is how this model will evolve in the future. Close monitoring is essential to ensure quality of care and to maintain the core objective of the CAG-model ‘facilitating access to ART care’ in a cost and time saving manner.

High attrition among HIV-infected patients with advanced disease treated in an intermediary referral center in Maputo, Mozambique. Glob Health Action 2014; 7:23758. [PMID: 24717189 PMCID: PMC3982117 DOI: 10.3402/gha.v7.23758] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2014] [Revised: 02/24/2014] [Accepted: 03/08/2014] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND In Mozambique, antiretroviral therapy (ART) scale-up has been successfully implemented. However, attrition in care remains a major programmatic challenge. In 2009, an intermediary-level HIV referral center was created in Maputo to ensure access to specialized care for HIV-infected patients with complications (advanced clinical-immunological stage, Kaposi sarcoma, or suspected ART failure). OBJECTIVE To determine the attrition from care and to identify risk factors that lead to high attrition among patients referred to an intermediary-level HIV referral center. DESIGN This was a retrospective cohort study from 2009 to 2011. RESULTS A total of 1,657 patients were enrolled, 847 (51%) were men, the mean age was 36 years (standard deviation: 11), the mean CD4 count was 27 cells/µl (interquartile range: 11-44), and one-third were severely malnourished. The main reasons for referral were advanced clinical stages (WHO stages 3 and 4, and CD4 count <50 cells/µl) in 70% of the cases, and 19% had Kaposi sarcoma. The overall attrition rate was 28.7 per 100 person-years (PYs) - the mortality rate was 5.0 (95% confidence interval [CI]: 4.2-5.9) per 100 PYs, and the loss-to-follow-up rate was 23.7 (95% CI: 21.9-25.6) per 100 PYs. There were 793 attritions - 137 deaths and 656 lost to follow-up (LTFU); 77% of all attrition happened within the first year. The factors independently associated with attrition were male sex (adjusted hazard ratio [aHR]: 1.15, 95% CI: 1.0-1.3), low body mass index (aHR: 1.51, 95% CI: 1.2-1.8), WHO clinical stage 3 or 4 (aHR: 1.30, 95% CI: 1.0-1.6; and aHR: 1.91, 95% CI: 1.4-2.5), later year of enrollment (aHR 1.61, 95% CI 1.3-1.9), and 'being already on ART' at enrollment (aHR 13.71, 95% CI 11.4-16.4). CONCLUSIONS Attrition rates among HIV-infected patients enrolled in an intermediary referral center were high, mainly related to advanced stage of clinical disease. Measures are required to address this, including innovative strategies for HIV-testing uptake, earlier ART initiation and nutritional supplementation, and special attention to men and those who are already on ART at enrolment. Qualitative research is required to understand the reasons for being LTFU and design informed evidence-based interventions.

Abstract
Background To improve retention on ART, Médecins Sans Frontières, the Ministry of Health and patients piloted a community-based antiretroviral distribution and adherence monitoring model through Community ART Groups (CAG) in Tete, Mozambique. By December 2012, almost 6000 patients on ART had formed groups of whom 95.7% were retained in care. We conducted a qualitative study to evaluate the relevance, dynamic and impact of the CAG model on patients, their communities and the healthcare system. Methods Between October 2011 and May 2012, we conducted 16 focus group discussions and 24 in-depth interviews with the major stakeholders involved in the CAG model. Audio-recorded data were transcribed verbatim and analysed using a grounded theory approach. Results Six key themes emerged from the data: 1) Barriers to access HIV care, 2) CAG functioning and actors involved, 3) Benefits for CAG members, 4) Impacts of CAG beyond the group members, 5) Setbacks, and 6) Acceptance and future expectations of the CAG model. The model provides cost and time savings, certainty of ART access and mutual peer support resulting in better adherence to treatment. Through the active role of patients, HIV information could be conveyed to the broader community, leading to an increased uptake of services and positive transformation of the identity of people living with HIV. Potential pitfalls included limited access to CAG for those most vulnerable to defaulting, some inequity to patients in individual ART care and a high dependency on counsellors. Conclusion The CAG model resulted in active patient involvement and empowerment, and the creation of a supportive environment improving the ART retention. It also sparked a reorientation of healthcare services towards the community and strengthened community actions. Successful implementation and scalability requires (a) the acceptance of patients as partners in health, (b) adequate resources, and (c) a well-functioning monitoring and management system.

Abstract
The large-scale introduction of HIV and AIDS services in Mozambique from 2000 onwards occurred in the context of deep political commitment to sovereign nation-building and an important transition in the nation's health system. Simultaneously, the international community encountered a willing state partner that recognised the need to take action against the HIV epidemic. This article examines two critical policy shifts: sustained international funding and public health system integration (the move from parallel to integrated HIV services). The Mozambican government struggles to support its national health system against privatisation, NGO competition and internal brain drain. This is a sovereignty issue. However, the dominant discourse on self-determination shows a contradictory twist: it is part of the political rhetoric to keep the sovereignty discourse alive, while the real challenge is coordination, not partnerships. Nevertheless, we need more anthropological studies to understand the political implications of global health funding and governance. Other studies need to examine the consequences of public health system integration for the quality of access to health care.

Abstract
Background Since establishment of Zimbabwe's National Antiretroviral Therapy (ART) Programme in 2004, ART provision has expanded from <5,000 to 369,431 adults by 2011. However, patient outcomes are unexplored. Objective To determine improvement in health status, retention and factors associated with attrition among HIV-infected patients on ART. Methods A retrospective review of abstracted patient records of adults ≥15 years who initiated ART from 2007 to 2009 was done. Frequencies and medians were calculated for rates of retention in care and changes in key health status outcomes at 6, 12, 24 and 36 months respectively. Cox proportional hazards models were used to determine factors associated with attrition. Results Of the 3,919 patients, 64% were female, 86% were either WHO clinical stage III or IV. Rates of patient retention at 6, 12, 24 and 36 months were 90.7%, 78.1%, 68.8% and 64.4%, respectively. After ART initiation, median weight gains at 6, 12, and 24 months were 3, 4.5, and 5.0 kgs whilst median CD4+ cell count gains at 6, 12 and 24 months were 122, 157 and 279 cells/µL respectively. Factors associated with an increased risk of attrition included male gender (AHR 1.2; 95% CI, 1.1–1.4), baseline WHO stage IV (AHR 1.7; 95% CI, 1.1–2.6), lower baseline body weight (AHR 2.0; 95% CI, 1.4–2. 8) and accessing care from higher level healthcare facilities (AHR 3.5; 95% 1.1–11.2). Conclusions Our findings with regard to retention as well as clinical and immunological improvements following uptake of ART, are similar to what has been found in other settings. Factors influencing attrition also mirror those found in other parts of sub-Saharan Africa. These findings suggest the need to strengthen earlier diagnosis and treatment to further improve treatment outcomes. Whilst decentralisation improves ART coverage it should be coupled with strategies aimed at improving patient retention.

Predictors of attrition and immunological failure in HIV-1 patients on highly active antiretroviral therapy from different healthcare settings in Mozambique. PLoS One 2013; 8:e82718. [PMID: 24376569 PMCID: PMC3869714 DOI: 10.1371/journal.pone.0082718] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2013] [Accepted: 10/27/2013] [Indexed: 11/18/2022] Open
Abstract
In Mozambique, the evaluation of retention in HIV care and ART programmes is limited. To assess rate and predictors of attrition (no retention in care) and HAART effectiveness in HIV-1 infected patients who pay for medication and laboratory testing in Mozambique, we conducted a multicenter survey of HIV-1-infected patients who started HAART during 2002–2006. Cox proportional hazard models were used to assess risk of attrition and of therapy failure. Overall, 142 patients from 16 healthcare centers located in the capital city Maputo were followed-up for 22.2 months (12.1–46.7). The retention rate was 75%, 48% and 37% after one, two and three years, respectively. Risk of attrition was lower in patients with higher baseline CD4 count (P = 0.022) and attending healthcare center 1 (HCC1) (P = 0.013). The proportion of individuals with CD4 count ≤200 cells/µL was 55% (78/142) at baseline and decreased to 6% (3/52) at 36 months. Among the patients with available VL, 86% (64/74) achieved undetectable VL levels. The rate of immunologic failure was 17.2% (95% CI: 12.6–22.9) per 100 person-years. Risk of failure was associated to higher baseline CD4 count (P = 0.002), likely reflecting low adherence levels, and decreased with baseline VL ≥10,000 copies/mL (P = 0.033). These results suggest that HAART can be effective in HIV-1 infected patients from Mozambique that pay for their medication and laboratory testing. Further studies are required to identify the causes for low retention rates in patients with low CD4 counts and to better understand the association between healthcare setting and attrition rate.

Abstract
BACKGROUND In 2004, the Mozambican Ministry of Health began a national scale-up of antiretroviral therapy (ART) using a vertical model of HIV clinics colocated within large urban hospitals. In 2006, the ministry expanded access by integrating ART into primary health care clinics. METHODS We conducted a retrospective cohort study including adult ART-naive patients initiating ART between January 2006 and June 2008 in public sector clinics in Manica and Sofala provinces. Cox proportional hazards models with robust variances were used to estimate the association between clinic model (vertical/integrated), clinic location (urban/rural), and clinic experience (first 6 months/post first 6 months) and attrition occurring in early patient follow-up (≤ 6 months) and attrition occurring in late patient follow-up (>6 months), while controlling for age, sex, education, pre-ART CD4 count, World Health Organization stage and pharmacy staff burden. RESULTS A total of 11,775 patients from 17 clinics were studied. The overall attrition rate was 37 per 100 person-years. Patients attending integrated clinics had a higher risk of attrition in late follow-up [hazard ratio (HR) = 1.75; 95% confidence interval (CI): 1.04 to 2.94], and patients attending urban clinics (HR = 0.57; 95% CI: 0.35 to 0.91) had a lower risk of attrition in late follow-up. Though not statistically significant, clinics open for longer than 6 months (HR = 0.71; 95% CI: 0.49 to 1.04) had a lower risk of attrition in early follow-up. CONCLUSIONS Patients attending vertical clinics had a lower risk of attrition. Utilizing primary health clinics to implement ART is necessary to reach higher levels of coverage; however, further implementation strategies should be developed to improve patient retention in these settings.

Abstract
BACKGROUND Retention of children in HIV care is essential for prevention of disease progression and mortality. METHODS Retrospective cohort of children (aged 0 to <15 years) initiating antiretroviral treatment (ART) at health facilities in Kenya, Mozambique, Rwanda, and Tanzania, from January 2005 to June 2011. Retention was defined as the proportion of children known to be alive and attending care at their initiation facility; lost to follow-up (LTF) was defined as no clinic visit for more than 6 months. Cumulative incidence of ascertained survival and retention after ART initiation was estimated through 24 months using Kaplan-Meier methods. Factors associated with LTF and death were assessed using Cox proportional hazard modeling. RESULTS A total of 17,712 children initiated ART at 192 facilities: median age was 4.6 years [interquartile ratio (IQR), 1.9-8.3], median CD4 percent was 15% (IQR, 10-20) for children younger than 5 years and 265 cells per microliter (IQR, 111-461) for children aged 5 years or older. At 12 and 24 months, 80% and 72% of children were retained with 16% and 22% LTF and 5% and 7% known deaths, respectively. Retention ranged from 71% to 95% at 12 months and from 62% to 93% at 24 months across countries, respectively, and was lowest for children younger than 1 year (51% at 24 months). LTF and death were highest in children younger than 1 year and children with advanced disease. CONCLUSIONS Retention was lowest in young children and differed across country programs. Young children and those with advanced disease are at highest risk for LTF and death. Further evaluation of patient- and program-level factors is needed to improve health outcomes.

Abstract
In sub-Saharan Africa models of care need to adapt to support continued scale up of antiretroviral therapy (ART) and retain millions in care. Task shifting, coupled with community participation has the potential to address the workforce gap, decongest health services, improve ART coverage, and to sustain retention of patients on ART over the long-term. The evidence supporting different models of community participation for ART care, or community-based ART, in sub-Saharan Africa, was reviewed. In Uganda and Kenya community health workers or volunteers delivered ART at home. In Mozambique people living with HIV/AIDS (PLWHA) self-formed community-based ART groups to deliver ART in the community. These examples of community ART programs made treatment more accessible and affordable. However, to achieve success some major challenges need to be overcome: first, community programs need to be driven, owned by and embedded in the communities. Second, an enabling and supportive environment is needed to ensure that task shifting to lay staff and PLWHA is effective and quality services are provided. Finally, a long term vision and commitment from national governments and international donors is required. Exploration of the cost, effectiveness, and sustainability of the different community-based ART models in different contexts will be needed.

Abstract
Introduction While increasing access to antiretroviral therapy (ART) is reported from many African countries, data on effective coverage particular from settings without external support or research remains scarce. We examined and report effective coverage data from a public ART program in rural Uganda. Methods We conducted a retrospective cohort study at all ART-providing governmental health facilities in Iganga District, Eastern Uganda. Based on all HIV patients registered between April 2004 and September 2009 (n = 4775), we assessed indicators of program performance and determined rates of retention and Cox proportional hazards for attrition. Effective ART coverage was calculated using projections (SPECTRUM software) adapted to the district demographic structure and number of people receiving ART. Results By September 2009, district public sector effective ART coverage was 10.3% for adults and 1.9% for children. After a median follow-up of 26.9 months, overall ART retention was 54.7%. The probability of retention was 0.72 (95% confidence interval (CI) 0.69–0.75) at 12 and 0.58 (CI 0.54–0.62) at 36 months after ART initiation. Individual health facilities differed considerably regarding performance indicators and retention. Overall, 198 (16.9%) individual files of 1171 registered ART patients were lost. Young adult age (15–24 years) had a higher risk of attrition (HR 2.1, CI 1.4–3.2) as well as WHO stage I (HR 4.8, CI 1.9–11.8) and WHO stage IV (HR 2.5, CI 1.3–4.7). An interval ≥6 weeks between HIV testing and ART initiation was associated with a reduced risk (HR 0.6, CI 0.47–0.78). Conclusion Compared to reported national data effective ART coverage in Iganga District was low. Intensified efforts to improve access, retention in care, and quality of documentation are urgently needed. Children and young adults require special attention in the program.

Abstract
BACKGROUND In resource-limited settings, decentralization of HIV care and treatment is a cornerstone of universal care and rapid scale-up. We compared trends in pediatric enrollment and outcomes at primary (PHFs) vs secondary/tertiary health facilities (SHFs). METHODS Using aggregate program data reported quarterly from 274 public facilities in Kenya, Lesotho, Mozambique, Rwanda, and Tanzania from January 2008 to March 2010, we examined trends in number of children younger than 15 years of age initiating antiretroviral treatment (ART) by facility type. We compared clinic-level lost to follow-up (LTFU) and mortality per 100 person-years (PYs) on ART during the period by facility type. RESULTS During the 2-year period, 17,155 children enrolled in HIV care and 8475 initiated ART in 182 (66%) PHFs and 92(34%) SHFs. PHFs increased from 56 to 182, whereas SHFs increased from 72 to 92 sites. SHFs accounted for 71% of children initiating ART; however, the proportion of children initiating ART each quarter at PHFs increased from 17% (129) to 44% (463) in conjunction with an increase in PHFs during observation period. The average LTFU and mortality rates for children on ART were 9.8/100 PYs and 5.2/100 PYs, respectively, at PHFs and 20.2/100 PYs and 6.0/100 PYs, respectively, at SHFs. Adjusted models show PHFs associated with lower LTFU (adjusted rate ratio = 0.55; P = 0.022) and lower mortality (adjusted rate ratio = 0.66; P = 0.028). CONCLUSIONS The expansion of pediatric services to PHFs has resulted in increased numbers of children on ART. Early findings suggest lower rates of LTFU and mortality at PHFs. Successful scale-up will require further expansion of pediatric services within PHFs.

Abstract
Adherence to antiretroviral therapy is an important predictor of long-term treatment success. Adherence can be differentiated between early adherence challenges, that are about integrating pill-taking into daily life, and long-term adherence, where patients struggle to maintain clinical connections and interrupt clinical care and medication use. In resource-limited settings, treatment interruptions may be more useful predictors of patient outcome than pill-taking alone. Interventions that are aimed at providing support to patients and their individual challenges to prevent interruptions in treatment and care may have a greater impact over time on clinically important outcomes than interventions targeted only at pill-taking behaviours.

HIV treatment and care in resource-constrained environments: challenges for the next decade. J Int AIDS Soc 2012; 15:17334.

Abstract
Many successes have been achieved in HIV care in low- and middle-income countries (LMIC): increased number of HIV-infected individuals receiving antiretroviral treatment (ART), wide decentralization, reduction in morbidity and mortality and accessibility to cheapest drugs. However, these successes should not hide existing failures and difficulties. In this paper, we underline several key challenges. First, ensure long-term financing, increase available resources, in order to meet the increasing needs, and redistribute the overall budget in a concerted way amongst donors. Second, increase ART coverage and treat the many eligible patients who have not yet started ART. Competition amongst countries is expected to become a strong driving force in encouraging the least efficient to join better performing countries. Third, decrease early mortality on ART, by improving access to prevention, case-finding and treatment of tuberculosis and invasive bacterial diseases and by getting people to start ART much earlier. Fourth, move on from WHO 2006 to WHO 2010 guidelines. Raising the cut-off point for starting ART to 350 CD4/mm3 needs changing paradigm, adopting opt-out approach, facilitating pro-active testing, facilitating task shifting and increasing staff recruitments. Phasing out stavudine needs acting for a drastic reduction in the costs of other drugs. Scaling up routine viral load needs a mobilization for lower prices of reagents and equipments, as well as efforts in relation to point-of-care automation and to maintenance. The latter is a key step to boost the utilization of second-line regimens, which are currently dramatically under prescribed. Finally, other challenges are to reduce lost-to-follow-up rates; manage lifelong treatment and care for long-term morbidity, including drug toxicity, residual AIDS and HIV-non-AIDS morbidity and aging-related morbidity; and be able to face unforeseen events such as socio-political and military crisis. An old African proverb states that the growth of a deep-rooted tree cannot be stopped. Our tree is well rooted in existing field experience and is, therefore, expected to grow. In order for us to let it grow, long-term cost-effectiveness approach and life-saving evidence-based programming should replace short-term budgeting approach.

Abstract
Global AIDS programs such as the US President's Emergency Plan for AIDS Relief (PEPFAR) face a challenging health care management transition. HIV care must evolve from vertically-organized, externally-supported efforts to sustainable, locally controlled components that are integrated into the horizontal primary health care systems of host nations. We compared four southern African nations in AIDS care, financial, literacy, and health worker capacity parameters (2005 to 2009) to contrast in their capacities to absorb the huge HIV care and prevention endeavors that are now managed with international technical and fiscal support. Botswana has a relatively high national income, a small population, and an advanced HIV/AIDS care program; it is well poised to take on management of its HIV/AIDS programs. South Africa has had a slower start, given HIV denialism philosophies of the previous government leadership. Nonetheless, South Africa has the national income, health care management, and health worker capacity to succeed in fully local management. The sheer magnitude of the burden is daunting, however, and South Africa will need continuing fiscal assistance. In contrast, Zambia and Mozambique have comparatively lower per capita incomes, many fewer health care workers per capita, and lower national literacy rates. It is improbable that fully independent management of their HIV programs is feasible on the timetable being contemplated by donors, nor is locally sustainable financing conceivable at present. A tailored nation-by-nation approach is needed for the transition to full local capacitation; donor nation policymakers must ensure that global resources and technical support are not removed prematurely.
