Abstract
People living with HIV face multiple psychosocial challenges. In a large, predominantly rural Ethiopian region, 1799 HIV patients new to care were enrolled from 32 sites in a cluster randomized trial using trained community support workers with HIV to provide individual health education, counseling and social support. Participants received annual surveys through 36 months using items drawn from the Centre for Epidemiologic Studies Depression Scale-10, Medical Outcome Study Social Support Survey, and HIV/AIDS Stigma Instrument-PLWA. At 12 months (using linear mixed effects regression models controlling for enrollment site clustering), intervention participants had greater emotional/informational and tangible assistance social support scores, and lower scores assessing depression symptoms and negative self-perception due to HIV status. A significant treatment effect at 36 months was also seen on scores assessing emotional/informational social support, depression symptoms, and internalized stigma. An intervention using peer community support workers with HIV to provide individualized informational and psychological support had a positive impact on the emotional health of people living with HIV who were new to care.(ClinicalTrials.gov protocol ID: 1410S54203, May 19, 2015).

Abstract
BACKGROUND With countries moving toward the World Health Organization's "Treat All" recommendation, there is a need to initiate more HIV-infected persons into antiretroviral therapy (ART). In resource-limited settings, task shifting is 1 approach that can address clinician shortages. SETTING Uganda. METHODS We conducted a randomized controlled trial to test if nurse-initiated and monitored ART (NIMART) is noninferior to clinician-initiated and monitored ART in HIV-infected adults in Uganda. Study participants were HIV-infected, ART-naive, and clinically stable adults. The primary outcome was a composite end point of any of the following: all-cause mortality, virological failure, toxicity, and loss to follow-up at 12 months post-ART initiation. RESULTS Over half of the study cohort (1,760) was women (54.9%). The mean age was 35.1 years (SD 9.51). Five hundred thirty-three (31.6%) participants experienced the composite end point. At 12 months post-ART initiation, nurse-initiated and monitored ART was noninferior to clinician-initiated and monitored ART. The intention-to-treat site-adjusted risk differences for the composite end point were -4.1 [97.5% confidence interval (CI): = -9.8 to 0.2] with complete case analysis and -3.4 (97.5% CI: = -9.1 to 2.5) with multiple imputation analysis. Per-protocol site-adjusted risk differences were -3.6 (97.5% CI: = -10.5 to 0.6) for complete case analysis and -3.1 (-8.8 to 2.8) for multiple imputation analysis. This difference was within hypothesized margins (6%) for noninferiority. CONCLUSIONS Nurses were noninferior to clinicians for initiation and monitoring of ART. Task shifting to trained nurses is a viable means to increase access to ART. Future studies should evaluate NIMART for other groups (e.g., children, adolescents, and unstable patients).

Strategies for retention of heterosexual men in HIV care in sub-Saharan Africa: A systematic review. PLoS One 2021; 16:e0246471.

Abstract
Expansion of Antiretroviral Therapy (ART) programs in sub-Saharan Africa (SSA) has increased the number of people accessing treatment. However, the number of males accessing and being retained along the human immunodeficiency virus (HIV) care cascade is significantly below the UNAIDS target. Male gender has been associated with poor retention in HIV care programs, and little is known about strategies that reduce attrition of men in ART programs. This review aimed to summarize any studies on strategies to improve retention of heterosexual males in HIV care in SSA. An electronic search was conducted through Ovid® for three databases (MEDLINE®, Embase and Global Health). Studies reporting interventions aimed at improving retention among heterosexual men along the HIV care cascade were reviewed. The inclusion criteria included randomized-controlled trials (RCTs), prospective or retrospective cohort studies that studied adult males (≥15years of age), conducted in SSA and published between January 2005 and April 2019 with an update from 2019 to 2020. The search returned 1958 articles, and 14 studies from eight countries met the inclusion criteria were presented using the PRISMA guidelines. A narrative synthesis was conducted. Six studies explored community-based adherence support groups while three compared use of facility versus community-based delivery models. Three studies measured the effect of national identity cards, disclosure of HIV status, six-monthly clinic visits and distance from the health center. Four studies measured risk of attrition from care using hazard ratios ranging from 1.2–1.8, four studies documented attrition proportions at an average of 40.0% and two studies an average rate of attrition of 43.4/1000PYs. Most (62%) included studies were retrospective cohorts, subject to risk of allocation and outcome assessment bias. A pooled analysis was not performed because of heterogeneity of studies and outcome definitions. No studies have explored heterosexual male- centered interventions in HIV care. However, in included studies that explored retention in both males and females, there were high rates of attrition in males. More male-centered interventions need to be studied preferably in RCTs.

The effects of decentralising antiretroviral therapy care delivery on health outcomes for adolescents and young adults in low- and middle-income countries: a systematic review. Glob Health Action 2020; 12:1668596. [PMID: 31558145 PMCID: PMC6781195 DOI: 10.1080/16549716.2019.1668596] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/28/2022] Open
Abstract
Background: Decentralisation of antiretroviral therapy has been implemented to scale up HIV care provision for patients in resource-limited countries. Youth living with HIV demonstrate the poorest care outcomes, compared to other age groups. Objectives: To systematically evaluate evidence on the effects of decentralising facility-based HIV care on care outcomes for youth living with HIV in low- and middle-income countries. Methods: A systematic review was conducted through 12 electronic databases of peer-reviewed articles, conference abstracts, and grey literature; contacting relevant experts; and hand-searching references. Records were included if they were published after 1 January 1996 (advent of triple-drug ART) and reported health outcomes for decentralised and centralised care, separately, or evaluated the effect of decentralised care on care outcomes. Two authors independently screened search results. When age-disaggregated data (10-24 years old) were required for inclusion, we contacted study authors for data abstraction. Implementation fidelity of decentralisation, study quality, and risk of bias was assessed using the TIDieR checklist, CASP checklists, and ROBINS-I tool, respectively. Results: Of 11 potentially eligible studies, two studies from sub-Saharan Africa met inclusion criteria after data disaggregation by age. The studies and abstracted data were insufficiently homogenous in implementation and study design to justify meta-analysis. However, evidence suggests the potential for decentralised care to result in at least equivalent attrition-related outcomes (retention in care and mortality) for youth within decentralised HIV care. Limited sample size and significant selection and allocation bias confound clear, generalisable conclusions for youth living with HIV in resource-limited settings. Conclusions: There is a paucity of evidence for the effects of decentralising HIV care for youth living in resource-limited settings, particularly recent evidence reflective of the current HIV care landscape. Further work is required to rigorously analyse the effects of decentralising HIV care to inform policymakers and care providers, particularly as demand for HIV care in this population grows.

Abstract
BACKGROUND Organization of HIV care and treatment services, including clinic staffing and services, may shape clinical and financial outcomes, yet there has been little attempt to describe different models of HIV care in sub-Saharan Africa (SSA). Information about the relative benefits and drawbacks of different models could inform the scale-up of antiretroviral therapy (ART) and associated services in resource-limited settings (RLS), especially in light of expanded client populations with country adoption of WHO's test and treat recommendation. METHODS We characterized task-shifting/task-sharing practices in 19 diverse ART clinics in Tanzania, Uganda, and Zambia and used cluster analysis to identify unique models of service provision. We ran descriptive statistics to explore how the clusters varied by environmental factors and programmatic characteristics. Finally, we employed the Delphi Method to make systematic use of expert opinions to ensure that the cluster variables were meaningful in the context of actual task-shifting of ART services in SSA. RESULTS The cluster analysis identified three task-shifting/task-sharing models. The main differences across models were the availability of medical doctors, the scope of clinical responsibility assigned to nurses, and the use of lay health care workers. Patterns of healthcare staffing in HIV service delivery were associated with different environmental factors (e.g., health facility levels, urban vs. rural settings) and programme characteristics (e.g., community ART distribution or integrated tuberculosis treatment on-site). CONCLUSIONS Understanding the relative advantages and disadvantages of different models of care can help national programmes adapt to increased client load, select optimal adherence strategies within decentralized models of care, and identify differentiated models of care for clients to meet the growing needs of long-term ART patients who require more complicated treatment management.

Abstract
BACKGROUND Discontinuation of antiretroviral therapy (ART) reduces the immunological benefit of treatment and increases complications related to human immune-deficiency virus (HIV). However, the risk factors for ART discontinuation are poorly understood in developing countries particularly in Ethiopia. This review aimed to assess the best available evidence regarding risk factors for ART discontinuation in Ethiopia. METHODS Quantitative studies conducted in Ethiopia between 2002 and 2015 that evaluated factors associated with ART discontinuation were sought across six major databases. Only English language articles were included. This review considered studies that included the following outcome: ART treatment discontinuation, i.e. 'lost to follow up', 'defaulting' and 'stopping medication'. Meta- analysis was performed with Mantel Haenszel method using Revman-5 software. Summary statistics were expressed as pooled odds ratio with 95% confidence intervals at a p-value of <0.05. RESULTS Nine (9) studies met the criteria of the search. Five (5) were retrospective studies, 3 were case control studies, and 1 was a prospective cohort study. The total sample size in the included studies was 62,156. Being rural dweller (OR = 2.1, 95%CI: 1.5-2.7, I2 = 60%), being illiterate (OR = 1.5, 95%CI: 1.1-2.1), being not married (OR = 1.4, 95%CI: 1.1-1.8), being alcohol drinker (OR = 2.9, 95%CI: 1.9-4.4, I2 = 39%), being tobacco smoker (OR = 2.6, 95%CI: 1.6-4.3, I2 = 74%), having mental illness (OR = 2.7, 95%CI: 1.6-4.6, I2 = 0%) and being bed ridden functional status (OR = 2.3, 95%CI: 1.5-3.4, I2 = 37%) were risk factors for ART discontinuation. Whereas, having HIV positive partner (OR = 0.4, 95%CI: 0.3-0.6, I2 = 69%) and being co-infected with Tb/HIV (OR = 0.6, 95%CI: 0.4-0.9, I2 = 0%) were protective factors. CONCLUSION Demographic, behavioral and clinical factors influenced ART treatment discontinuation. Hence, we recommend strengthening decentralization of HIV care services in remote areas, strengthening of ART task shifting, application of seek-test-treat-succeed model, and integration of smoking cession strategies and mental health care into the routine HIV care program.

Abstract
BACKGROUND Regular monitoring of HIV patients who are receiving antiretroviral therapy (ART) is required to ensure patient benefits and the long-term effectiveness and sustainability of ART programs. Prompted by WHO recommendations for expansion and decentralization of HIV treatment and care in low and middle income countries, we conducted a systematic review to assess the feasibility of treatment monitoring in these settings. METHODS A comprehensive search strategy was developed using a combination of MeSH and free text terms relevant to HIV treatment and care, health service delivery, health service accessibility, decentralization and other relevant terms. Five electronic databases and two conference websites were searched to identify relevant studies conducted in LMICs, published in English between Jan 2006 and Dec 2015. Outcomes of interest included the proportion of patients who received treatment monitoring and health system factors related to monitoring of patients on ART under decentralized HIV service delivery models. RESULTS From 5363 records retrieved, twenty studies were included in the review; all but one was conducted in sub-Saharan African countries. The majority of studies (15/20) had relatively short follow-up duration (≤24 months), and only two studies were specifically designed to assess treatment monitoring practices. The most frequently studied follow-up period was 12 months and a wide range of treatment monitoring coverage was observed. The reported proportions of patients on ART who received CD4 monitoring ranged from very low (6%; N = 2145) to very high (95%; N = 488). The median uptake of viral load monitoring was 86% with studies in program settings reporting coverage as low as 14%. Overall, the longer the follow-up period, the lower the proportion of patients who received regular monitoring tests; and programs in rural areas reported low coverage of laboratory monitoring. Moreover, uptake in the context of research had significantly better where monitoring was done by dedicated research staff. In the absence of point of care (POC) testing, the limited capacity for blood sample transportation between clinic and laboratory and poor quality of nursing staff were identified as a major barrier for treatment monitoring practice. CONCLUSIONS There is a paucity of data on the uptake of treatment monitoring, particularly with longer-term follow-up. Wide variation in access to both virological and immunological regular monitoring was observed, with some clinics in well-resourced settings supported by external donors achieving high coverage. The feasibility of treatment monitoring, particularly in decentralized settings of HIV treatment and care may thus be of concern and requires further study. Significant investment in POC diagnostic technologies and, improving the quality of and training for nursing staff is required to ensure effective scale up of ART programs towards the targets of 90-90-90 by the year 2020.

Abstract
Policy-makers and clinicians are faced with a gap of evidence to guide policy on standards for HIV outpatient care. Ongoing debates include which settings of care improve health outcomes, and how many HIV-infected patients a health-care provider should treat to gain and maintain expertise. In this article, we evaluate the studies that link health-care facility and care provider characteristics (i.e., structural factors) to health outcomes in HIV-infected patients. We searched the electronic databases MEDLINE, PUBMED, and EMBASE from inception until 1 January 2015. We included a total of 28 observational studies that were conducted after the introduction of combination antiretroviral therapy in 1996. Three aspects of the available research linking the structure to quality of HIV outpatient care were evaluated: (1) assessed structural characteristics (i.e., health-care facility and care provider characteristics); (2) measures of quality of HIV outpatient care; and (3) reported associations between structural characteristics and quality of care. Rather than scarcity of data, it is the diversity in methodology in the identified studies and the inconsistency of their results that led us to the conclusion that the scientific evidence is too weak to guide policy in HIV outpatient care. We provide recommendations on how to address this heterogeneity in future studies and offer specific suggestions for further reading that could be of interest for clinicians and researchers.

Abstract
INTRODUCTION Although Ethiopia has been scaling up the antiretroviral therapy (ART) services, low retention in care of patients remains one of the main obstacles to treatment success. We report data on retention in care and its associated determinants in Tigray, Ethiopia. METHODS We used data from the CASA project, a prospective observational and multi-site study of a cohort of HIV-infected patients who initiated ART for the first time in Tigray. Four participating health facilities (HFs) located in the South of Tigray were considered for this study. Patients were followed for one year after ART initiation. The main outcome measure was represented by the current retention in care, defined as the proportion of patients who were alive and receiving ART at the same HF one year after ART initiation. Patients who started ART between January 1, 2013 and December 31, 2013 were included in this analysis. Patients were followed for one year after ART initiation. The determinants of retention were analysed using univariate and multivariate Cox Proportional Hazards model with robust sandwich estimates to account for within HF correlation. RESULTS The four participating HFs in Tigray were able to retain overall 85.1% of their patients after one year from starting ART. Loss to follow-up (5.5%) and transfers to other HF (6.6) were the main determinant of attrition. A multivariate analysis shows that the factors significantly associated with retention were the type of HF, gender and active TB. Alamata health center was the HF with the highest attrition rate (HR 2.99, 95% CI: 2.77-3.23). Active TB (HR 1.72, 95% CI: 1.23-2.41) and gender (HR 1.64, 95% CI: 1.10-2.56) were also significantly associated with attrition. CONCLUSIONS Although Ethiopia has significantly improved access to the ART program, achieving and maintaining a satisfactory long-term retention rate is a future goal. This is difficult because of different retention rates among HFs. Moreover specific interventions should be directed to people of different sex to improve retention in care in male population.

Implementation and Operational Research: Evaluation of Swaziland's Hub-and-Spoke Model for Decentralizing Access to Antiretroviral Therapy Services. J Acquir Immune Defic Syndr 2015; 69:e1-12.

Abstract
BACKGROUND In 2007, Swaziland initiated a hub-and-spoke model for decentralizing antiretroviral therapy (ART) access. Decentralization was facilitated through (1) down-referral of stable ART patients from overburdened central facilities (hubs) to primary health care clinics (spokes) and (2) ART initiation at spokes (spoke initiation). METHODS We conducted a nationally representative retrospective cohort study among adult ART enrollees during 2004-2010 to assess the effect of down-referral and spoke-initiation on rates of loss to follow-up (LTFU), death, and attrition (death or LTFU). Sixteen of 31 hubs were randomly selected using probability-proportional-to-size sampling. Seven selected facilities had initiated the hub-and-spoke model by study start. At these facilities, 1149 of 24,782 hub-initiated and maintained and 878 of 7722 down-referred or spoke-initiated patient records were randomly selected and analyzed. At the 9 hub-only facilities, 483 of 6638 records were randomly selected and analyzed. Multivariable proportional hazards regression was used to assess effect of down-referral (a time-varying covariate) and spoke-initiation on outcomes. RESULTS At ART initiation, median age was 35, 65% were female, and median CD4 count was 147 cells per microliter. Controlling for known confounders, down-referral was strongly protective against LTFU [adjusted hazard ratio (AHR) 0.38; 95% confidence interval (CI): 0.29 to 0.50] and attrition (AHR = 0.50; 95% CI: 0.34 to 0.76) but not mortality. Compared with hub-initiated and maintained patients, spoke-initiated patients had lower LTFU (AHR 0.59; 95% CI: 0.45 to 0.77) and attrition rates (AHR 0.60; 95% CI: 0.47 to 0.77), but not mortality. CONCLUSIONS Down-referral and spoke-initiation within a hub-and-spoke ART decentralization model were protective against LTFU and overall attrition and could facilitate future ART program expansion.

Abstract
The global HIV pandemic began to expand rapidly in southern Africa a decade later than was noted in central Africa, Europe, the Caribbean, and North America. Multiple factors played a role in this rapid expansion which led Southern Africa to become the most heavily afflicted region for HIV/AIDS globally. In this issue of Current HIV/AIDS Reports, investigators with active research interests in the region have reviewed key elements of the causes of and responses to the epidemic. Putative causes of the high HIV prevalence in the region are discussed, including host and viral biology, human behavior, politics and policy, structural factors, health services, health workforce, migration, traditional healers' role, and other issues. Regional epidemiological trends are described and forecasted. Issues related to the continuum of HIV care and treatment are highlighted. We hope that the reviews will prove useful to those policymakers, health care workers, and scientists who are striving to reduce the burden of HIV in the southern African region, as well as prove insightful for key issues of broader global relevance.

Abstract
Formalized task shifting structures have been used to rapidly scale up antiretroviral service delivery to underserved populations in several countries, and may be a promising mechanism for accomplishing universal health coverage. However, studies evaluating the quality of service delivery through task shifting have largely ignored the patient perspective, focusing on health outcomes and acceptability to health care providers and regulatory bodies, despite studies worldwide that have shown the significance of patient satisfaction as an indicator of quality. This study aimed to measure patient satisfaction with task shifting of antiretroviral services in hospitals and health centres in four regions of Ethiopia. This cross-sectional study used data collected from a time-motion study of patient services paired with 665 patient exit interviews in a stratified random sample of antiretroviral therapy clinics in 21 hospitals and 40 health centres in 2012. Data were analyzed using f-tests across provider types, and multivariate logistic regression to identify determinants of patient satisfaction. Most (528 of 665) patients were satisfied or somewhat satisfied with the services received, but patients who received services from nurses and health officers were significantly more likely to report satisfaction than those who received services from doctors [odds ratio (OR) 0.26, P < 0.01]. Investments in the health facility were associated with higher satisfaction (OR 1.07, P < 0.01), while costs to patients of over 120 birr were associated with lower satisfaction (OR 0.14, P < 0.05). This study showed high levels of patient satisfaction with task shifting in Ethiopia. The evidence generated by this study complements previous biomedical and health care provider/regulatory acceptability studies to support the inclusion of task shifting as a mechanism for scaling-up health services to achieve universal health coverage, particularly for underserved areas facing severe health worker shortages.

Abstract
OBJECTIVES In response to the lack of evidence-based guidance for how to continue scaling up antiretroviral therapy (ART) in ways that make optimal use of limited resources, to assess comparative studies of ART service delivery models implemented in sub-Saharan Africa. METHODS A systematic literature search and analysis of studies that compared two or more methods of ART service delivery using either CD4 count or viral load as a primary outcome. RESULTS Most studies identified in this review were small and non-randomised, with low statistical power. Four of the 30 articles identified by this review conclude that nurse management of ART compares favourably to physician management. Seven provide evidence of the viability of managing ART at lower levels within the health system, and one indicates that vertical and integrated ART programmes can achieve similar outcomes. Five articles show that community/home-based ART management can be as effective as facility-based ART management. Five of seven articles investigating community support link it to better clinical outcomes. The results of four studies suggest that directly observed therapy may not be an important component of ART programmes. CONCLUSIONS Given that the scale-up of antiretroviral therapy represents the most sweeping change in healthcare delivery in sub-Saharan Africa in recent years, it is surprising to not find more evidence from comparative studies to inform implementation strategies. The studies reported on a wide range of service delivery models, making it difficult to draw conclusions about some models. The strongest evidence was related to the feasibility of decentralisation and task-shifting, both of which appear to be effective strategies.

Abstract
BACKGROUND The high levels of healthcare worker shortage is recognised as a severe impediment to increasing patients' access to antiretroviral therapy. This is particularly of concern where the burden of disease is greatest and the access to trained doctors is limited.This review aims to better inform HIV care programmes that are currently underway, and those planned, by assessing if task-shifting care from doctors to non-doctors provides both high quality and safe care for all patients requiring antiretroviral treatment. OBJECTIVES To evaluate the quality of initiation and maintenance of HIV/AIDS care in models that task shift care from doctors to non-doctors. SEARCH METHODS We conducted a comprehensive search to identify all relevant studies regardless of language or publication status (published, unpublished, in press, and in progress) from 1 January 1996 to 28 March 2014, with major HIV/AIDS conferences searched 23 May 2014. We had also contacted relevant organizations and researchers. Key words included MeSH terms and free-text terms relevant to 'task shifting', 'skill mix', 'integration of tasks', 'service delivery' and 'health services accessibility'. SELECTION CRITERIA We included controlled trials (randomised or non-randomised), controlled-before and after studies, and cohort studies (prospective or retrospective) comparing doctor-led antiretroviral therapy delivery to delivery that included another cadre of health worker other than a doctor, for initiating treatment, continuing treatment, or both, in HIV infected patients. DATA COLLECTION AND ANALYSIS Two authors independently screened titles, abstracts and descriptor terms of the results of the electronic search and applied our eligibility criteria using a standardized eligibility form to full texts of potentially eligible or uncertain abstracts. Two reviewers independently extracted data on standardized data extraction forms. Where possible, data were pooled using random effects meta-analysis. We assessed evidence quality with GRADE methodology. MAIN RESULTS Ten studies met our inclusion criteria, all of which were conducted in Africa. Of these four were randomised controlled trials while the remaining six were cohort studies.From the trial data, when nurses initiated and provided follow-up HIV therapy, there was high quality evidence of no difference in death at one year, unadjusted risk ratio was 0.96 (95% CI 0.82 to 1.12), one trial, cluster adjusted n = 2770. There was moderate quality evidence of lower rates of losses to follow-up at one year, relative risk of 0.73 (95% CI 0.55 to 0.97). From the cohort data, there was low quality evidence that there may be an increased risk of death in the task shifting group, relative risk 1.23 (95% CI 1.14 to 1.33, two cohorts, n = 39 160) and very low quality data reporting no difference in patients lost to follow-up between groups, relative risk 0.30 (95% CI 0.05 to 1.94).From the trial data, when doctors initiated therapy and nurses provided follow-up, there was moderate quality evidence that there is probably no difference in death compared with doctor-led care at one year, relative risk of 0.89 (95% CI 0.59 to 1.32), two trials, cluster adjusted n = 4332. There was moderate quality evidence that there is probably no difference in the numbers of patients lost to follow-up at one year, relative risk 1.27 (95% CI 0.92 to 1.77), P = 0.15. From the cohort data, there is very low quality data that death at one year may be lower in the task shifting group, relative risk 0.19 (95% CI 0.05 to 0.78), one cohort, n = 2772, and very low quality evidence that loss to follow-up was reduced, relative risk 0.34 (95% CI 0.18 to 0.66).From the trial data, for maintenance therapy delivered in the community there was moderate quality evidence that there is probably no difference in mortality when doctors deliver care in the hospital or specially trained field workers provide home-based maintenance care and antiretroviral therapy at one year, relative risk 1.0 (95% CI 0.62 to 1.62), 1 trial, cluster adjusted n = 559. There is moderate quality evidence from this trial that losses to follow-up are probably no different at one year, relative risk 0.52 (0.12 to 2.3), P = 0.39. The cohort studies did not report on one year follow-up for these outcomes.Across the studies that reported on virological and immunological outcomes, there was no clear evidence of difference whether a doctor or nurse or clinical officer delivered therapy. Three studies report on costs to patients, indicating a reduction in travel costs to treatment facilities where task shifting was occurring closer to patients homes. There is conflicting evidence regarding the relative cost to the health system, as implementation of the strategy may increase costs. The two studies reporting the patient and staff perceptions of the quality of care, report good acceptability of the service by patients, and general acceptance by doctors of the shifting of roles. One trial reported on the time to initiation of antiretroviral therapy, finding no clear evidence of a difference between groups. The same trial reports on new diagnosis of tuberculosis which favours nurse initiation of HIV care for increasing the numbers of diagnoses of tuberculosis made. AUTHORS' CONCLUSIONS Our review found moderate quality evidence that shifting responsibility from doctors to adequately trained and supported nurses or community health workers for managing HIV patients probably does not decrease the quality of care and, in the case of nurse initiated care, may decrease the numbers of patients lost to follow-up.

Abstract
Background Antiretroviral treatment (ART) was provided to more than nine million people by the end of 2012. Although ART programs in resource-limited settings have expanded treatment, inadequate retention in care has been a challenge. Ethiopia has been scaling up ART and improving retention (defined as continuous engagement of patients in care) in care. We aimed to analyze the ART program in Ethiopia. Methods A mix of quantitative and qualitative methods was used. Routine ART program data was used to study ART scale up and patient retention in care. In-depth interviews and focus group discussions were conducted with program managers. Results The number of people receiving ART in Ethiopia increased from less than 9,000 in 2005 to more than 439, 000 in 2013. Initially, the public health approach, health system strengthening, community mobilization and provision of care and support services allowed scaling up of ART services. While ART was being scaled up, retention was recognized to be insufficient. To improve retention, a second wave of interventions, related to programmatic, structural, socio-cultural, and patient information systems, have been implemented. Retention rate increased from 77% in 2004/5 to 92% in 2012/13. Conclusion Ethiopia has been able to scale up ART and improve retention in care in spite of its limited resources. This has been possible due to interventions by the ART program, supported by health systems strengthening, community-based organizations and the communities themselves. ART programs in resource-limited settings need to put in place similar measures to scale up ART and retain patients in care.

Abstract
Background Evidence from several sub-Saharan countries support nurse-initiated antiretroviral treatment as a feasible alternative to doctor-led models characteristic of early responses to the HIV epidemic. However, service delivery models shown to be effective in one country may not be readily adopted in another. This study used an implementation research approach to assist policy makers and other stakeholders to assess the acceptability and feasibility of task shifting in the Namibian context. Methods The Namibian Ministry of Health and Social Services implemented a Task Shifting Demonstration Project (TSDP) at 9 sites at different levels of the health system. Six months after implementation, a mixed methods evaluation was conducted. Seventy semi-structured interviews were conducted with patients, managers, doctors and nurses directly involved with the TSDP. Physician-evaluators observed and compared health service provision between doctors and nurses for 40 patients (80 observations), documenting performance in agreement with the national guidelines on 13 clinical care indicators. Results Doctors, nurses, and patients interviewed believed task shifting would improve access to and quality of HIV services. Doctors and nurses both reported an increase in nurses’ skills as a result of the project. Observation data showed doctors and nurses were in considerable agreement (>80%) with each other on all dimensions of HIV care and ≥90% on eight dimensions. To ensure success of national scale-up of the task shifting model, challenges involving infrastructure, on-going mentoring, and nursing scope of practice should be anticipated and addressed. Conclusion In combination with findings from other studies in the region, data from the TSDP provided critical and timely information to the Namibian Ministry of Health and Social Services, thus helping to move evidence into action. Small-scale implementation research projects enable stakeholders to learn by doing, and provide an opportunity to test and modify the intervention before expansion.

Abstract
BACKGROUND Current service delivery systems do not reach all people in need of antiretroviral therapy (ART). In order to inform the operational and service delivery section of the WHO 2013 consolidated antiretroviral guidelines, our objective was to summarize systematic reviews on integrating ART delivery into maternal, newborn, and child health (MNCH) care settings in countries with generalized epidemics, tuberculosis (TB) treatment settings in which the burden of HIV and TB is high, and settings providing opiate substitution therapy (OST); and decentralizing ART into primary health facilities and communities. DESIGN A summary of systematic reviews. METHODS The reviewers searched PubMed, Embase, PsycINFO, Web of Science, CENTRAL, and the WHO Index Medicus databases. Randomized controlled trials and observational cohort studies were included if they compared ART coverage, retention in HIV care, and/or mortality in MNCH, TB, or OST facilities providing ART with MNCH, TB, or OST facilities providing ART services separately; or primary health facilities or communities providing ART with hospitals providing ART. RESULTS The reviewers identified 28 studies on integration and decentralization. Antiretroviral therapy integration into MNCH facilities improved ART coverage (relative risk [RR] 1.37, 95% confidence interval [CI] 1.05-1.79) and led to comparable retention in care. ART integration into TB treatment settings improved ART coverage (RR 1.83, 95% CI 1.48-2.23) and led to a nonsignificant reduction in mortality (RR 0.55, 95% CI 0.29-1.05). The limited data on ART integration into OST services indicated comparable rates of ART coverage, retention, and mortality. Partial decentralization into primary health facilities improved retention (RR 1.05, 95% CI 1.01-1.09) and reduced mortality (RR 0.34, 95% CI 0.13-0.87). Full decentralization improved retention (RR 1.12, 95% CI 1.08-1.17) and led to comparable mortality. Community-based ART led to comparable rates of retention and mortality. CONCLUSION Integrating ART into MNCH, TB, and OST services was often associated with improvements in ART coverage, and decentralization of ART into primary health facilities and communities was often associated with improved retention. Neither integration nor decentralization was associated with adverse outcomes. These data contributed to recommendations in the WHO 2013 consolidated antiretroviral guidelines to integrate ART delivery into MNCH, TB, and OST services and to decentralize ART.

Abstract
Background Detection of active tuberculosis (TB) before antiretroviral therapy (ART) initiation is important, but optimal diagnostic methods for use in resource-limited settings are lacking. We assessed the prevalence of TB, evaluated the diagnostic yield of Xpert MTB/RIF in comparison with smear microscopy and culture, and the impact of Xpert results on clinical management in HIV-positive adults eligible for ART at health centers in a region of Ethiopia. Methods Participants were prospectively recruited and followed up at 5 health centers. Trained nurses collected data on socio-demographic characteristics, medical history and symptoms, and performed physical examination. Two paired morning sputum samples were obtained, and lymph node aspirates in case of lymphadenopathy. Diagnostic yield of Xpert MTB/RIF in sputum was compared with smear microscopy and liquid culture. Results TB was diagnosed in 145/812 participants (17.9%), with bacteriological confirmation in 137 (16.9%). Among bacteriologically confirmed cases, 31 were smear-positive (22.6%), 96 were Xpert-positive (70.1%), and 123 were culture-positive (89.8%). Xpert MTB/RIF increased the TB detection rate by 64 cases (47.4%) compared with smear microscopy. The overall sensitivity of Xpert MTB/RIF was 66.4%, and was not significantly lower when testing one compared with two samples. While Xpert MTB/RIF was 46.7% sensitive among patients with CD4 cell counts >200 cells/mm3, this increased to 82.9% in those with CD4 cell counts ≤100 cells/mm3. Compared with Xpert-positive TB patients, Xpert-negative cases had less advanced HIV and TB disease characteristics. Conclusions Previously undiagnosed TB is common among HIV-positive individuals managed in Ethiopian health centers. Xpert MTB/RIF increased TB case detection, especially in patients with advanced immunosuppression. An algorithm based on the use of a single morning sputum sample for individuals with negative sputum smear microscopy could be considered for intensified case finding in patients eligible for ART. However, technical and cost-effectiveness issues relevant for low-income countries warrant further study.

Abstract
BACKGROUND There is a severe healthcare workforce shortage in sub Saharan Africa, which threatens achieving the Millennium Development Goals and attaining an AIDS-free generation. The strength of a healthcare system depends on the skills, competencies, values and availability of its workforce. A well-trained and competent laboratory technologist ensures accurate and reliable results for use in prevention, diagnosis, care and treatment of diseases. METHODS An assessment of existing preservice education of five medical laboratory schools, followed by remedial intervention and monitoring was conducted. The remedial interventions included 1) standardizing curriculum and implementation; 2) training faculty staff on pedagogical methods and quality management systems; 3) providing teaching materials; and 4) procuring equipment for teaching laboratories to provide practical skills to complement didactic education. RESULTS A total of 2,230 undergraduate students from the five universities benefitted from the standardized curriculum. University of Gondar accounted for 252 of 2,230 (11.3%) of the students, Addis Ababa University for 663 (29.7%), Jimma University for 649 (29.1%), Haramaya University for 429 (19.2%) and Hawassa University for 237 (10.6%) of the students. Together the universities graduated 388 and 312 laboratory technologists in 2010/2011 and 2011/2012 academic year, respectively. Practical hands-on training and experience with well-equipped laboratories enhanced and ensured skilled, confident and competent laboratory technologists upon graduation. CONCLUSIONS Strengthening preservice laboratory education is feasible in resource-limited settings, and emphasizing its merits (ample local capacity, country ownership and sustainability) provides a valuable source of competent laboratory technologists to relieve an overstretched healthcare system.

Abstract
BACKGROUND HIV/TB coinfection remains a major challenge even after the initiation of HAART. Little is known about Mycobacterium tuberculosis (Mtb) specific immune restoration in relation to immunologic and virologic outcomes after long-term HAART during co-infections with latent and active TB. METHODS A total of 232 adults, including 59 HIV patients with clinical TB (HIV + TB+), 125 HIV patients without clinical TB (HIV + TB-), 13 HIV negative active TB patients (HIV-TB+), and 10 HIV negative Tuberculin Skin TST positive (HIV-TST+), and 25 HIV-TST- individuals were recruited. HAART was initiated in 113 HIV + patients (28 TB + and 85 TB-), and anti-TB treatment for all TB cases. CD4+ T-cell count, HIV RNA load, and IFN-γ responses to ESAT-6/CFP-10 were measured at baseline, 6 months (M6), 18 months (M18) and 24 months (M24) after HAART initiation. RESULTS The majority of HIV + TB- (70%, 81%, 84%) as well as HIV + TB + patients (60%, 77%, 80%) had virologic success (HIV RNA < 50 copies/ml) by M6, M18 and M24, respectively. HAART also significantly increased CD4+ T-cell counts at 2 years in HIV + TB + (from 110.3 to 289.9 cells/μl), HIV + TB- patients (197.8 to 332.3 cells/μl), HIV + TST- (199 to 347 cells/μl) and HIV + TST + individuals (195 to 319 cells/μl). Overall, there was no significant difference in the percentage of patients that achieved virologic success and in total CD4+ counts increased between HIV patients with and without TB or LTBI. The Mtb specific IFN-γ response at baseline was significantly lower in HIV + TB + (3.6 pg/ml) compared to HIV-TB + patients (34.4 pg/ml) and HIV + TST + (46.3 pg/ml) individuals; and in HIV-TB + patients compared to HIV-TST + individuals (491.2 pg/ml). By M18 on HAART, the IFN-γ response remained impaired in HIV + TB + patients (18.1 pg/ml) while it normalized in HIV + TST + individuals (from 46.3 to 414.2 pg/ml). CONCLUSIONS Our data show that clinical and latent TB infections do not influence virologic and immunologic outcomes of ART in HIV patients. Despite this, HAART was unable to restore optimal TB responsiveness as measured by Mtb specific IFN-γ response in HIV/TB patients. Improvement of Mtb-specific immune restoration should be the focus of future therapeutic strategies.

Abstract
INTRODUCTION A severe healthcare worker shortage in sub-Saharan Africa is inhibiting the expansion of HIV treatment. Task shifting, the transfer of antiretroviral therapy (ART) management and initiation from doctors to nurses and other non-physician clinicians, has been proposed to address this problem. However, many health officials remain wary about implementing task shifting policies due to concerns that non-physicians will provide care inferior to physicians. To determine if non-physician-provided HIV care does result in equivalent outcomes to physician-provided care, a meta-analysis was performed. METHODS Online databases were searched using a predefined strategy. The results for four primary outcomes were combined using a random effects model with sub-groups of non-physician-managed ART and -initiated ART. TB diagnosis rates, adherence, weight gain and patient satisfaction were summarized qualitatively. RESULTS Mortality (N=59,666) had similar outcomes for non-physicians and physicians, with a hazard ratio of 1.05 (CI: 0.88-1.26). The increase in CD4 levels at one year, as a difference in means of 2.3 (N=17,142, CI: -12.7-17.3), and viral failure at one year, as a risk ratio of 0.89 (N=10,344, CI: 0.65-1.23), were similar for physicians and non-physicians. Interestingly, loss to follow-up (LTFU) (N=53,435) was reduced for non-physicians with a hazard ratio of 0.72 (CI: 0.56-0.94). TB diagnosis rates, adherence and weight gain were similar for non-physicians and physicians. Patient satisfaction appeared higher for non-physicians in qualitative components of studies and was attributed to non-physicians spending more time with patients as well as providing more holistic care. CONCLUSIONS Non-physician-provided HIV care results in equivalent outcomes to care provided by physicians and may result in decreased LTFU rates.

Abstract
BACKGROUND Policy makers, health staff and communities recognise that health services in lower- and middle-income countries need to improve people's access to HIV treatment and retention to treatment programmes. One strategy is to move antiretroviral delivery from hospitals to more peripheral health facilities or even beyond health facilities. This could increase the number of people with access to care, improve health outcomes, and enhance retention in treatment programmes. On the other hand, providing care at less sophisticated levels in the health service or at community-level may decrease quality of care and result in worse health outcomes. To address these uncertainties, we summarised the research studies examining the risks and benefits of decentralising antiretroviral therapy service delivery. OBJECTIVES To assess the effects of various models that decentralised HIV treatment and care to more basic levels in the health system for initiating and maintaining antiretroviral therapy. SEARCH METHODS We conducted a comprehensive search to identify all relevant studies regardless of language or publication status (published, unpublished, in press, and in progress) from 1 January 1996 to 31 March 2013, and contacted relevant organisations and researchers. The search terms included 'decentralisation', 'down referral', 'delivery of health care', and 'health services accessibility'. SELECTION CRITERIA Our inclusion criteria were controlled trials (randomised and non-randomised), controlled-before and after studies, and cohorts (prospective and retrospective) in which HIV-infected people were either initiated on antiretroviral therapy or maintained on therapy in a decentralised setting in lower- and middle-income countries. We define decentralisation as providing treatment at a more basic level in the health system to the comparator. DATA COLLECTION AND ANALYSIS Two authors applied the inclusion criteria and extracted data independently. We designed a framework to describe different decentralisation strategies, and then grouped studies against these strategies. Data were pooled using random-effects meta-analysis. Because loss to follow up in HIV programmes is known to include some deaths, we used attrition as our primary outcome, defined as death plus loss to follow-up. We assessed evidence quality with GRADE methodology. MAIN RESULTS Sixteen studies met the inclusion criteria, all but one were from Africa, comprising two cluster randomised trials and 14 cohort studies. Antiretroviral therapy started at a hospital and maintained at a health centre (partial decentralisation) probably reduces attrition (RR 0.46, 95% CI 0.29 to 0.71, 4 studies, 39 090 patients, moderate quality evidence). There may be fewer patients lost to care with this model (RR 0.55, 95% CI 0.45 to 0.69, low quality evidence).We are uncertain whether there is a difference in attrition for antiretroviral therapy started and maintained at a health centre (full decentralisation) compared to a hospital at 12 months (RR 0.70, 95% CI 0.47 to 1.02; four studies, 56 360 patients, very low quality evidence), but there are probably fewer patients lost to care with this model (RR 0.3, 95% CI 0.17 to 0.54, moderate quality evidence).When antiretroviral maintenance therapy is delivered at home by trained volunteers, there is probably no difference in attrition at 12 months (RR 0.95, 95% CI 0.62 to 1.46, two trials, 1453 patients, moderate quality evidence). AUTHORS' CONCLUSIONS Decentralisation of HIV care aims to improve patient access and retention in care. Most data were from good quality cohort studies but confounding between site of treatment and outcomes cannot be excluded. Nevertheless, this review found that attrition appears to be lower in partial decentralisation models of treatment, where antiretrovirals were started at hospital and continued in the health centre; with antiretroviral drugs started and continued at health centres, no difference in attrition was detected, but there were fewer patients lost to care. For antiretroviral therapy provided at home by trained volunteers, no difference in outcomes were detected when compared to facility-based care.

Abstract
Goals of universal "test and treat" will never be fully realized if testing acceptance remains low, including rural areas, where HIV is increasingly recognized. We surveyed 250 randomly selected households from a rural Ethiopian town (Arba Minch) and surrounding villages about HIV testing experience, knowledge, and attitudes. Of the 558 adults, 45% were never HIV tested. Those never tested for HIV were more likely to be (P < .05) ≥45 years, rural villagers, and unaware of the benefits of antiretroviral therapy treatment and that persons with HIV can appear healthy; they were more likely to believe HIV-infected persons would be stigmatized and unsupported by their communities. Of those never tested, 70% were interested in HIV testing if offered. Despite recommendations that all persons be HIV tested, almost half of the adult residents in this rural community were never tested. Programs to increase HIV testing must include measures to address stigma/discrimination and knowledge deficits including benefits of early diagnosis and treatment.

Abstract
With 24% global disease burden and 3% global health workforce, the World Health Organization (WHO) designates the African region a critical workforce shortage area. Task shifting is a WHO-recommended strategy for countries with severe health worker shortages. It involves redistribution of healthcare tasks to make efficient use of available workers. Severe physician shortages, increasing HIV disease burden, and the need for improved access to antiretroviral treatment (ART) posed serious challenges for Africa. Shifting ART management from physicians to nurses was adopted by many countries to increase access to treatment. Growing evidence from Africa supports this model of care but little is known about its impact on African nurses. A PubMed literature search was conducted for most recent task-shifting studies in Africa between January 2009 and August 2012. Thirty-four studies were identified but 11 met criteria for "task shifting from physicians to nurses in HIV settings." The methodologies and findings related to patient outcome, nurses' perceived self-efficacy, and job satisfaction were summarized. Patient outcomes were measured in 10 of the studies and all demonstrated comparable results. Seven of eight studies showed no difference in mortality while five found better retention and lower client loss to follow-up in nurse-managed groups. Four studies showed that nurses built on existing nursing and HIV knowledge; improved HIV and other disease management skills; and had increased comfort levels with using treatment guidelines. Results of job satisfaction from three studies showed that nurses expressed "feelings of emotional rewards, accomplishment, prestige, and improved morale." In six studies, nurse-managed care was acceptable to patients in five studies, nurses in two studies, and majority of physicians and program managers in one study. Nurse-managed care had comparable outcomes and retained more patients but only two studies "directly" assessed nurses' perceptions. Research exploring nurses' response, self-efficacy, and job satisfaction are critically to sustainability.

Abstract
BACKGROUND Task shifting, defined for this review as the shifting of ART initiation and management from physicians to nurses, has been proposed as a possible method to increase access to HIV treatment in Sub-Saharan Africa. OBJECTIVE To critically evaluate the literature on task shifting, determining if there is evidence to support this view. METHODS A systematic search of the literature was undertaken, with both peer reviewed publications and conference abstracts presenting original data eligible for inclusion. Studies were evaluated according to methodology and discussion of confounding factors. RESULTS We identified 25 articles which evaluated the effect of task shifting on access to ART. The evidence was mixed. Although there is a significant body of field reports indicating that task shifting increases access, these studies were of low methodological quality. The only randomized controlled trial included in this review did not find that task shifting increased in access. CONCLUSION Task shifting appears to be most effective at increasing access when combined with other interventions and financial support. There is a need for more research into the effects of task shifting policies, especially randomized controlled trials and high quality cohort studies.
