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.

Developing the national community health assistant strategy in Zambia: a policy analysis. Health Res Policy Syst 2013; 11:24. [PMID: 23870454 PMCID: PMC3724745 DOI: 10.1186/1478-4505-11-24] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2012] [Accepted: 07/11/2013] [Indexed: 12/03/2022] Open
Abstract
Background In 2010, the Ministry of Health in Zambia developed the National Community Health Assistant strategy, aiming to integrate community health workers (CHWs) into national health plans by creating a new group of workers, called community health assistants (CHAs). The aim of the paper is to analyse the CHA policy development process and the factors that influenced its evolution and content. A policy analysis approach was used to analyse the policy reform process. Methodology Data were gathered through review of documents, participant observation and key informant interviews with CHA strategic team members in Lusaka district, and senior officials at the district level in Kapiri Mposhi district where some CHAs have been deployed. Results The strategy was developed in order to address the human resources for health shortage and the challenges facing the community-based health workforce in Zambia. However, some actors within the strategic team were more influential than others in informing the policy agenda, determining the process, and shaping the content. These actors negotiated with professional/statutory bodies and health unions on the need to develop the new cadre which resulted in compromises that enabled the policy process to move forward. International agencies also indirectly influenced the course as well as the content of the strategy. Some actors classified the process as both insufficiently consultative and rushed. Due to limited consultation, it was suggested that the policy content did not adequately address key policy content issues such as management of staff attrition, general professional development, and progression matters. Analysis of the process also showed that the strategy might create a new group of workers whose mandate is unclear to the existing group of health workers. Conclusions This paper highlights the complex nature of policy-making processes for integrating CHWs into the health system. It reiterates the need for recognising the fact that actors’ power or position in the political hierarchy may, more than their knowledge and understanding of the issue, play a disproportionate role in shaping the process as well as content of health policy reform.

Utilization of and Barriers to HIV and MCH Services among Community ART Group Members and Their Families in Tete, Mozambique. AIDS Res Treat 2013; 2013:937456. [PMID: 23956849 PMCID: PMC3730184 DOI: 10.1155/2013/937456] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2013] [Accepted: 07/02/2013] [Indexed: 11/18/2022] Open
Abstract
Mozambique continues to face many challenges in HIV and maternal and child health care (MCH). Community-based antiretroviral treatment groups (CAG) enhance retention to care among members, but whether such benefits extend to their families and to MCH remains unclear. In 2011 we studied utilization of HIV and MCH services among CAG members and their family aggregates in Changara, Mozambique, through a mixed-method assessment. We systematically revised all patient-held health cards from CAG members and their non-CAG family aggregate members and conducted semistructured group discussions on MCH topics. Quantitative data were analysed in EPI-Info. Qualitative data were manually thematically analysed. Information was retrieved from 1,624 persons, of which 420 were CAG members (26%). Good compliance with HIV treatment among CAG members was shared with non-CAG HIV-positive family members on treatment, but many family aggregate members remained without testing, and, when HIV positive, without HIV treatment. No positive effects from the CAG model were found for MCH service utilization. Barriers for utilization mentioned centred on insufficient knowledge, limited community-health facility collaboration, and structural health system limitations. CAG members were open to include MCH in their groups, offering the possibility to extend patient involvement to other health needs. We recommend that lessons learnt from HIV-based activism, patient involvement, and community participation are applied to broader SRH services, including MCH care.

Abstract
BACKGROUND Achieving high rates of adherence to antiretroviral therapy (ART) in resource-poor settings comprises serious, but different, challenges in both the first months of treatment and during the life-long maintenance phase. We measured the impact of a health system-oriented, facility-based intervention to improve clinic attendance and patient adherence. METHODS This was a quasi-experimental, longitudinal, controlled intervention study using interrupted time series analysis. The intervention consisted of (1) using a clinic appointment diary to track patient attendance and monitor monthly performance; (2) changing the mode of asking for self-reported adherence; (3) training staff on adherence concepts, intervention methods, and use of monitoring data; (4) conducting visits to support facility teams with the implementation.We conducted the study in 12 rural district hospitals (6 intervention, 6 control) in Kenya and randomly selected 1894 adult patients over 18 years of age in two cohorts: experienced patients on treatment for at least one year, and newly treated patients initiating ART during the study. Outcome measures were: attending the clinic on or before the date of a scheduled appointment, attending within 3 days of a scheduled appointment, reporting perfect adherence, and experiencing a gap in medication supply of more than 14 days. RESULTS Among experienced patients, the percentage attending the clinic on or before a scheduled appointment increased in both level (average total increase immediately after intervention) (+5.7%; 95% CI=2.1, 9.3) and trend (increase per month) (+1.0% per month; 95% CI=0.6, 1.5) following the intervention, as did the level and trend of those keeping appointments within three days (+4.2%; 95% CI=1.6, 6.7; and +0.8% per month; 95% CI=0.6, 1.1, respectively). The relative difference between the intervention and control groups based on the monthly difference in visit rates increased significantly in both level (+6.5; 95% CI=1.4, 11.6) and trend (1.0% per month; 95% CI=0.2, 1.8) following the intervention for experienced patients attending the clinic within 3 days of their scheduled appointments.The decrease in the percentage of experienced patients with a medication gap greater than 14 days approached statistical significance (-11.3%; 95% CI=-22.7, 0.1), and the change seemed to persist over 11 months after the intervention. All facility staff used appointment-keeping data to calculate adherence and discussed outcomes regularly. CONCLUSION The appointment-tracking system and monthly performance monitoring was strengthened, and patient attendance was improved. Scale-up to national level may be considered.

Nursing and midwifery regulation and HIV scale-up: establishing a baseline in East, Central and Southern Africa. J Int AIDS Soc 2013; 16:18051. [PMID: 23531276 PMCID: PMC3608854 DOI: 10.7448/ias.16.1.18051] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2012] [Revised: 01/30/2013] [Accepted: 02/13/2013] [Indexed: 11/24/2022] Open
Abstract
Introduction Shifting HIV treatment tasks from physicians to nurses and midwives is essential to scaling-up HIV services in sub-Saharan Africa. Updating nursing and midwifery regulations to include task shifting and pre-service education reform can help facilitate reaching new HIV targets. Donor-supported initiatives to update nursing and midwifery regulations are increasing. However, there are gaps in our knowledge of current practice and education regulations and a lack of information to target and implement regulation strengthening efforts. We conducted a survey of national nursing and midwifery councils to describe current nursing and midwifery regulations in 13 African countries. Methods A 30-item survey was administered to a convenience sample of 13 national nursing and midwifery regulatory body leaders in attendance at the PEPFAR-supported African Health Profession Regulatory Collaborative meeting in Nairobi, Kenya on 28 February, 2011. The survey contained questions on task shifting and regulations such as registration, licensure, scope of practice, pre-service education accreditation, continuing professional development and use of international guidelines. Survey data were analyzed to present country-level, comparative and regional findings. Results Task shifting to nurses and midwives was reported in 11 of the 13 countries. Eight countries updated their scope of practice within the last five years; only one reported their regulations to reflect task shifting. Countries vary with regard to licensure, pre-service accreditation and continuing professional development regulations in place. There was no consistency in terms of what standards were used to design national practice and education regulations. Discussion Many opportunities exist to assist countries to modernise regulations to incorporate important advancements from task shifting and pre-service reform. Appropriate, revised regulations can help sustain successful health workforce strategies and contribute to further scale-up HIV services and other global health priorities. Conclusions This study provides fundamental information from which to articulate goals and to measure the impact of regulation strengthening efforts.

Abstract
Understanding Health systems have now become the priority focus of researchers and policy makers, who have progressively moved away from a project-centred perspectives. The new tendency is to facilitate a convergence between health system developers and disease-specific programme managers in terms of both thinking and action, and to reconcile both approaches: one focusing on integrated health systems and improving the health status of the population and the other aiming at improving access to health care. Eye care interventions particularly in developing countries have generally been vertically implemented (e.g. trachoma, cataract surgeries) often with parallel organizational structures or specialised disease specific services. With the emergence of health system strengthening in health strategies and in the service delivery of interventions there is a need to clarify and examine inputs in terms governance, financing and management. This present paper aims to clarify key concepts in health system strengthening and describe the various components of the framework as applied in eye care interventions.

Abstract
BACKGROUND As antiretroviral treatment cohorts continue to expand, ensuring patient retention over time is an increasingly important concern. This, together with capacity and human resource constraints, has led to the consideration of out-of-clinic models for the delivery of antiretroviral therapy (ART). In 2008, Médecins Sans Frontières and the Provincial authorities launched a model of ART distribution and adherence monitoring by community groups in Tete Province, Mozambique. PROGRAMME APPROACH: Patients who were stable on ART for 6 months were informed about the community ART group model and invited to form groups. Group members had 4 key functions: facilitate monthly ART distribution to other group members in the community, provide adherence and social support, monitor outcomes, and ensure each group member undergoes a clinical consultation at least once every 6 months. Group members visit the health centre on a rotational basis, such that each group member has contact with the health service every 6 months. RESULTS Between February 2008 and May 2010, 1384 members were enrolled into 291 groups. Median follow-up time within a group was 12.9 months (IQR 8.5-14.1). During this time, 83 (6%) were transferred out, and of the 1301 patients still in community groups, 1269 (97.5%) were remaining in care, 30 (2%) had died, and 2 (0.2%) were lost to follow-up. DISCUSSION The Community ART Group model was initiated by patients to improve access, patient retention, and decongest health services. Early outcomes are highly satisfactory in terms of mortality and retention in care, lending support to such out-of-clinic approaches.

Abstract
Background Tanzania is experiencing acute shortages of Health Workers (HWs), a situation which has forced health managers, especially in the underserved districts, to hastily cope with health workers’ shortages by adopting task shifting. This has however been due to limited options for dealing with the crisis of health personnel. There are on-going discussions in the country on whether to scale up task shifting as one of the strategies for addressing health personnel crisis. However, these discussions are not backed up by rigorous scientific evidence. The aim of this paper is two-fold. Firstly, to describe the current situation of implementing task shifting in the context of acute shortages of health workers and, secondly, to provide a descriptive account of the potential opportunities or benefits and the likely challenges which might ensue as a result of implementing task shifting. Methods We employed in-depth interviews with informants at the district level and supplemented the information with additional interviews with informants at the national level. Interviews focussed on the informants’ practical experiences of implementing task shifting in their respective health facilities (district level) and their opinions regarding opportunities and challenges which might be associated with implementation of task shifting practices. At the national level, the main focus was on policy issues related to management of health personnel in the context of implementation of task shifting, in addition to seeking their opinions and perceptions regarding opportunities and challenges of implementing task shifting if formally adopted. Results Task shifting has been in practice for many years in Tanzania and has been perceived as an inevitable coping mechanism due to limited options for addressing health personnel shortages in the country. Majority of informants had the concern that quality of services is likely to be affected if appropriate policy infrastructures are not in place before formalising tasks shifting. There was also a perception that implementation of task shifting has ensured access to services especially in underserved remote areas. Professional discontent and challenges related to the management of health personnel policies were also perceived as important issues to consider when implementing task shifting practices. Additional resources for additional training and supervisory tasks were also considered important in the implementation of task shifting in order to make it deliver much the same way as it is for conventional modalities of delivering care. Conclusions Task shifting implementation occurs as an ad hoc coping mechanism to the existing shortages of health workers in many undeserved areas of the country, not just in the study site whose findings are reported in this paper. It is recommended that the most important thing to do now is not to determine whether task shifting is possible or effective but to define the limits of task shifting so as to reach a consensus on where it can have the strongest and most sustainable impact in the delivery of quality health services. Any action towards this end needs to be evidence-based.

Abstract
BACKGROUND Although access to life-saving treatment for patients infected with HIV in South Africa has improved substantially since 2004, treating all eligible patients (universal access) remains elusive. As the prices of antiretroviral drugs have dropped over the past years, availability of human resources may now be the most important barrier to achieving universal access to HIV treatment in Africa. We quantify the number of HIV health workers (HHWs) required to be added to the current HIV workforce to achieve universal access to HIV treatment in South Africa, under different eligibility criteria. METHODS We performed a time and motion study in three HIV clinics in a rural, primary care-based HIV treatment program in KwaZulu-Natal, South Africa, to estimate the average time per patient visit for doctors, nurses, and counselors. We estimated the additional number of HHWs needed to achieve universal access to HIV treatment within one year. RESULTS For universal access to HIV treatment for all patients with a CD4 cell count of ≤350 cells/μl, an additional 2,200 nurses, 3,800 counselors, and 300 doctors would be required, at additional annual salary cost of 929 million South African rand (ZAR), equivalent to US$ 141 million. For universal treatment ('treatment as prevention'), an additional 6,000 nurses, 11,000 counselors, and 800 doctors would be required, at an additional annual salary cost of ZAR 2.6 billion (US$ 400 million). CONCLUSIONS Universal access to HIV treatment for patients with a CD4 cell count of ≤350 cells/μl in South Africa may be affordable, but the number of HHWs available for HIV treatment will need to be substantially increased. Treatment as prevention strategies will require considerable additional financial and human resources commitments.

Abstract
BACKGROUND Despite the mounting attention for health systems and health systems theories, there is a persisting lack of consensus on their conceptualisation and strengthening. This paper contributes to structuring the debate, presenting landmarks in the development of health systems thinking against the backdrop of the policy context and its dominant actors. We argue that frameworks on health systems are products of their time, emerging from specific discourses. They are purposive, not neutrally descriptive, and are shaped by the agendas of their authors. DISCUSSION The evolution of thinking over time does not reflect a progressive accumulation of insights. Instead, theories and frameworks seem to develop in reaction to one another, partly in line with prevailing paradigms and partly as a response to the very different needs of their developers. The reform perspective considering health systems as projects to be engineered is fundamentally different from the organic view that considers a health system as a mirror of society. The co-existence of health systems and disease-focused approaches indicates that different frameworks are complementary but not synthetic. The contestation of theories and methods for health systems relates almost exclusively to low income countries. At the global level, health system strengthening is largely narrowed down to its instrumental dimension, whereby well-targeted and specific interventions are supposed to strengthen health services and systems or, more selectively, specific core functions essential to programmes. This is in contrast to a broader conceptualization of health systems as social institutions. SUMMARY Health systems theories and frameworks frame health, health systems and policies in particular political and public health paradigms. While there is a clear trend to try to understand the complexity of and dynamic relationships between elements of health systems, there is also a demand to provide frameworks that distinguish between health system interventions, and that allow mapping with a view of analysing their returns. The choice for a particular health system model to guide discussions and work should fit the purpose. The understanding of the underlying rationale of a chosen model facilitates an open dialogue about purpose and strategy.

Abstract
Background Task-shifting to lay community health providers is increasingly suggested as a potential strategy to overcome the barriers to sustainable antiretroviral treatment (ART) scale-up in high-HIV-prevalence, resource-limited settings. The dearth of systematic scientific evidence on the contributory role and function of these forms of community mobilisation has rendered a formal evaluation of the published results of existing community support programmes a research priority. Methods We reviewed the relevant published work for the period from November 2003 to December 2011 in accordance with the guidelines for a synthetic review. ISI Web of Knowledge, Science Direct, BioMed Central, OVID Medline, PubMed, Social Services Abstracts, and Sociological Abstracts and a number of relevant websites were searched. Results The reviewed literature reported an unambiguous positive impact of community support on a wide range of aspects, including access, coverage, adherence, virological and immunological outcomes, patient retention and survival. Looking at the mechanisms through which community support can impact ART programmes, the review indicates that community support initiatives are a promising strategy to address five often cited challenges to ART scale-up, namely (1) the lack of integration of ART services into the general health system; (2) the growing need for comprehensive care, (3) patient empowerment, (4) and defaulter tracing; and (5) the crippling shortage in human resources for health. The literature indicates that by linking HIV/AIDS-care to other primary health care programmes, by providing psychosocial care in addition to the technical-medical care from nurses and doctors, by empowering patients towards self-management and by tracing defaulters, well-organised community support initiatives are a vital part of any sustainable public-sector ART programme. Conclusions The review demonstrates that community support initiatives are a potentially effective strategy to address the growing shortage of health workers, and to broaden care to accommodate the needs associated with chronic HIV/AIDS. The existing evidence suggests that community support programmes, although not necessarily cheap or easy, remain a good investment to improve coverage of communities with much needed health services, such as ART. For this reason, health policy makers, managers, and providers must acknowledge and strengthen the role of community support in the fight against HIV/AIDS.

Abstract
Background In low-resource settings, patients’ use of multiple healthcare sources may complicate chronic care and clinical outcomes as antiretroviral therapy (ART) continues to expand. However, little is known regarding patterns, drivers and consequences of using multiple healthcare sources. We therefore investigated factors associated with patterns of plural healthcare usage among patients taking ART in diverse South African settings. Methods A cross-sectional study of patients taking ART was conducted in two rural and two urban sub-districts, involving 13 accredited facilities and 1266 participants selected through systematic random sampling. Structured questionnaires were used in interviews, and participant’s clinic records were reviewed. Data collected included household assets, healthcare access dimensions (availability, affordability and acceptability), healthcare utilization and pluralism, and laboratory-based outcomes. Multiple logistic regression models were fitted to identify predictors of healthcare pluralism and associations with treatment outcomes. Prior ethical approval and informed consent were obtained. Results Nineteen percent of respondents reported use of additional healthcare providers over and above their regular ART visits in the prior month. A further 15% of respondents reported additional expenditure on self-care (e.g. special foods). Access to health insurance (Adjusted odds ratio [aOR] 6.15) and disability grants (aOR 1.35) increased plural healthcare use. However, plural healthcare users were more likely to borrow money to finance healthcare (aOR 2.68), and incur catastrophic levels of healthcare expenditure (27%) than non-plural users (7%). Quality of care factors, such as perceived disrespect by staff (aOR 2.07) and lack of privacy (aOR 1.50) increased plural healthcare utilization. Plural healthcare utilization was associated with rural residence (aOR 1.97). Healthcare pluralism was not associated with missed visits or biological outcomes. Conclusion Increased plural healthcare utilization, inequitably distributed between rural and urban areas, is largely a function of higher socioeconomic status, better ability to finance healthcare and factors related to poor quality of care in ART clinics. Plural healthcare utilization may be an indication of patients’ dissatisfaction with perceived quality of ART care provided. Healthcare expenditure of a catastrophic nature remained a persistent complication. Plural healthcare utilization did not appear to influence clinical outcomes. However, there were potential negative impacts on the livelihoods of patients and their households.

Short-Term Rationing of Combination Antiretroviral Therapy: Impact on Morbidity, Mortality, and Loss to Follow-Up in a Large HIV Treatment Program in Western Kenya. AIDS Res Treat 2012; 2012:814564. [PMID: 22690332 PMCID: PMC3368312 DOI: 10.1155/2012/814564] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2011] [Accepted: 03/14/2012] [Indexed: 11/30/2022] Open
Abstract
Background. There was a 6-month shortage of antiretrovirals (cART) in Kenya. Methods. We assessed morbidity, mortality, and loss to follow-up (LTFU) in this retrospective analysis of adults who were enrolled during the six-month period with restricted cART (cap) or the six months prior (pre-cap) and eligible for cART at enrollment by the pre-cap standard. Cox models were used to adjust for potential confounders. Results. 9009 adults were eligible for analysis: 4,714 pre-cap and 4,295 during the cap. Median number of days from enrollment to cART initiation was 42 pre-cap and 56 for the cap (P < 0.001). After adjustment, individuals in the cap were at higher risk of mortality (HR = 1.21; 95% CI : 1.06–1.39) and LTFU (HR = 1.12; 95% CI : 1.04–1.22). There was no difference between the groups in their risk of developing a new AIDS-defining illness (HR = 0.92 95% CI 0.82–1.03). Conclusions. Rationing of cART, even for a relatively short period of six months, led to clinically adverse outcomes.

Abstract
BACKGROUND Most low and middle income countries (LMICs) are currently not on track to reach the health-related Millennium Development Goals (MDGs). One way to accelerate progress would be through the large-scale implementation of evidence-based health tools and interventions. This study aimed to: (a) explore the barriers that have impeded such scale-up in LMICs, and (b) lay out an "implementation research agenda"--a series of key research questions that need to be addressed in order to help overcome such barriers. METHODS Interviews were conducted with fourteen key informants, all of whom are academic leaders in the field of implementation science, who were purposively selected for their expertise in scaling up in LMICs. Interviews were transcribed by hand and manually coded to look for emerging themes related to the two study aims. Barriers to scaling up, and unanswered research questions, were organized into six categories, representing different components of the scaling up process: attributes of the intervention; attributes of the implementers; scale-up approach; attributes of the adopting community; socio-political, fiscal, and cultural context; and research context. RESULTS Factors impeding the success of scale-up that emerged from the key informant interviews, and which are areas for future investigation, include: complexity of the intervention and lack of technical consensus; limited human resource, leadership, management, and health systems capacity; poor application of proven diffusion techniques; lack of engagement of local implementers and of the adopting community; and inadequate integration of research into scale-up efforts. CONCLUSIONS Key steps in expanding the evidence base on implementation in LMICs include studying how to: simplify interventions; train "scale-up leaders" and health workers dedicated to scale-up; reach and engage communities; match the best delivery strategy to the specific health problem and context; and raise the low profile of implementation science.

Are Expert Patients an Untapped Resource for ART Provision in Sub-Saharan Africa? AIDS Res Treat 2012; 2012:749718.

Abstract
Since the introduction of antiretroviral treatment, HIV/AIDS can be framed as a chronic lifelong condition, requiring lifelong adherence to medication. Reinforcement of self-management through information, acquisition of problem solving skills, motivation, and peer support is expected to allow PLWHA to become involved as expert patients in the care management and to decrease the dependency on scarce skilled medical staff. We developed a conceptual framework to analyse how PLWHA can become expert patients and performed a literature review on involvement of PLWHA as expert patients in ART provision in Sub-Saharan Africa. This paper revealed two published examples: one on trained PLWHA in Kenya and another on self-formed peer groups in Mozambique. Both programs fit the concept of the expert patient and describe how community-embedded ART programs can be effective and improve the accessibility and affordability of ART. Using their day-to-day experience of living with HIV, expert patients are able to provide better fitting solutions to practical and psychosocial barriers to adherence. There is a need for careful design of models in which expert patients are involved in essential care functions, capacitated, and empowered to manage their condition and support fellow peers, as an untapped resource to control HIV/AIDS.

Abstract
OBJECTIVES The extent of the HIV epidemic in South Africa may render the public sector capacity inadequate to manage all patients requiring antiretroviral treatment (ART). Private practitioners are an underutilised resource. METHODS The authors developed a model of care using 72 private practitioners in five provinces in urban and rural areas of South Africa with centralised clinical support, training, pharmacy control and data management. The authors describe the programme, its quality control measures and patient outcomes using a cohort analysis. RESULTS Between January 2005 and December 2008, 9102 individuals were started on ART, 62% female, median age 34 years, median viral load 50,655 copies/ml and median baseline CD4 count 123 cells/μl. Retention (alive and in care) after 12 months was 63% in the 2005 cohort (646 of 1026) and remained similar in the other calendar years, 58%, 68% and 64% in 2006, 2007 and 2008, respectively. After 36 months, retention was 50% and 41% for those enrolled in 2005 and 2006, respectively. The percentage virally suppressed remained similar at 6 months, 82% vs 84%, 84% and 85% from 2005, 2006, 2007 to 2008, respectively, p=0.66; but improved slightly at 12 months, 78% vs 83%, 83% and 84% from 2005 to 2008, p=0.05. At 36 months, it was 84% and 82% for the 2005 and 2006 cohorts, respectively. CONCLUSIONS The results show that a well-managed private practitioner model can achieve comparable results to public services, although long-term retention needs further evaluation. This model of ART delivery can be used to expand access to ART in areas where the public sector is unable to meet the demand.

Prioritizing CD4 count monitoring in response to ART in resource-constrained settings: a retrospective application of prediction-based classification. PLoS Med 2012; 9:e1001207.

Abstract
BACKGROUND Global programs of anti-HIV treatment depend on sustained laboratory capacity to assess treatment initiation thresholds and treatment response over time. Currently, there is no valid alternative to CD4 count testing for monitoring immunologic responses to treatment, but laboratory cost and capacity limit access to CD4 testing in resource-constrained settings. Thus, methods to prioritize patients for CD4 count testing could improve treatment monitoring by optimizing resource allocation. METHODS AND FINDINGS Using a prospective cohort of HIV-infected patients (n=1,956) monitored upon antiretroviral therapy initiation in seven clinical sites with distinct geographical and socio-economic settings, we retrospectively apply a novel prediction-based classification (PBC) modeling method. The model uses repeatedly measured biomarkers (white blood cell count and lymphocyte percent) to predict CD4(+) T cell outcome through first-stage modeling and subsequent classification based on clinically relevant thresholds (CD4(+) T cell count of 200 or 350 cells/µl). The algorithm correctly classified 90% (cross-validation estimate=91.5%, standard deviation [SD]=4.5%) of CD4 count measurements <200 cells/µl in the first year of follow-up; if laboratory testing is applied only to patients predicted to be below the 200-cells/µl threshold, we estimate a potential savings of 54.3% (SD=4.2%) in CD4 testing capacity. A capacity savings of 34% (SD=3.9%) is predicted using a CD4 threshold of 350 cells/µl. Similar results were obtained over the 3 y of follow-up available (n=619). Limitations include a need for future economic healthcare outcome analysis, a need for assessment of extensibility beyond the 3-y observation time, and the need to assign a false positive threshold. CONCLUSIONS Our results support the use of PBC modeling as a triage point at the laboratory, lessening the need for laboratory-based CD4(+) T cell count testing; implementation of this tool could help optimize the use of laboratory resources, directing CD4 testing towards higher-risk patients. However, further prospective studies and economic analyses are needed to demonstrate that the PBC model can be effectively applied in clinical settings.

Abstract
Objective The World Health Organization (WHO) recommends shifting tasks from physicians to lower cadres for the delivery of antiretroviral treatment (ART) for countries short of physicians. Our objective was to evaluate the effectiveness and acceptability of ART delivery by health officers and nurses in Ethiopia. Methods A retrospective cohort study to evaluate outcomes of ART services in 25 health centresstaffed with health officers and/or nurses and 30 hospitals staffed with physicians in 2009. Median CD4-cell counts, mortality, loss to follow-up and retention were the primary outcomes. Interviews and focus group discussions were conducted with people living with HIV/AIDS, AIDS programme managers and health care providers to identify the types and acceptability of the tasks conducted by the health officers, nurses and community health workers. Results Health officers and nurses were providing ART, including ART prescription, for non-severe cases. The management of severe cases was exclusively the task of physicians. Community health workers were involved in adherence counselling and defaulter tracing. The baseline median CD4-cell counts per micro-liter of blood were 117 (interquartiles [IQ] 64,188) and 119 (IQ 67,190) at health centres and hospitals respectively. After 24 months on ART, the median CD4-cell counts per micro-literof blood increased to 321 (IQ 242, 414) and 301 (IQ 217, 411) at health centres and hospitals respectively. Retention in care was higher in health centres (76%, 95% confidence interval [CI] [73%-79%]) than hospitals (67%, 95% CI [66%-68%]). This difference is mainly due to the higher loss to follow-up rate in hospitals (25% versus 13%). Mortality was higher in health centres than hospitals (11% versus 8%), but the difference is not statistically significant. Service delivery by non-physicians was accepted by patients, health care providers and programme managers. However, the absence of a regulatory framework for task shifting, the lack of extra remuneration for the additional roles assumed by nurses and health officers, and the high cost for training and mentorship were identified as weaknesses. Conclusion ART delivery in health centres, based on health officers and nurses is feasible, effective and acceptable in Ethiopia. However, issues related to regulation, remuneration and cost need to be addressed for the sustainable implementation of these delivery models.

Abstract
INTRODUCTION Current health policy directions in Zambia are formulated in the National Health Strategic Plan. The Plan focuses on national health priorities, which include the human resources (HR) crisis. In this paper we describe the way the HRH establishment is distributed in the different provinces of Zambia, with a view to assess the dimension of shortages and of imbalances in the distribution of health workers by province and by level of care. POPULATION AND METHODS We used secondary data from the "March 2008 payroll data base", which lists all the public servants on the payroll of the Ministry of Health and of the National Health Service facilities. We computed rates and ratios and compared them. RESULTS The highest relative concentration of all categories of workers was observed in Northern, Eastern, Lusaka, Western and Luapula provinces (in decreasing order of number of health workers).The ratio of clinical officers (mid-level clinical practitioners) to general medical officer (doctors with university training) varied from 3.77 in the Lusaka to 19.33 in the Northwestern provinces. For registered nurses (3 to 4 years of mid-level training), the ratio went from 3.54 in the Western to 15.00 in Eastern provinces and for enrolled nurses (two years of basic training) from 4.91 in the Luapula to 36.18 in the Southern provinces.This unequal distribution was reflected in the ratio of population per cadre. The provincial distribution of personnel showed a skewed staff distribution in favour of urbanized provinces, e.g. in Lusaka's doctor: population ratio was 1: 6,247 compared to Northern Province's ratio of 1: 65,763.In the whole country, the data set showed only 109 staff in health posts: 1 clinical officer, 3 environmental health technologists, 2 registered nurses, 12 enrolled midwives, 32 enrolled nurses, and 59 other.The vacancy rates for level 3 facilities(central hospitals, national level) varied from 5% in Lusaka to 38% in Copperbelt Province; for level 2 facilities (provincial level hospitals), from 30% for Western to 70% for Copperbelt Province; for level 1 facilities (district level hospitals), from 54% for the Southern to 80% for the Western provinces; for rural health centres, vacancies varied from 15% to 63% (for Lusaka and Luapula provinces respectively); for urban health centres the observed vacancy rates varied from 13% for the Lusaka to 96% for the Western provinces. We observed significant shortages in most staff categories, except for support staff, which had a significant surplus. DISCUSSION AND CONCLUSIONS This case study documents how a peaceful, politically stable African country with a longstanding tradition of strategic management of the health sector and with a track record of innovative approaches dealt with its HRH problems, but still remains with a major absolute and relative shortage of health workers. The case of Zambia reinforces the idea that training more staff is necessary to address the human resources crisis, but it is not sufficient and has to be completed with measures to mitigate attrition and to increase productivity.

Abstract
INTRODUCTION Human resource shortages are viewed as one of the primary obstacles to provide effective services to growing patient populations receiving antiretroviral therapy (ART) and to expand ART access further. We examined the relationship of patient volume, human resource levels, and patient characteristics with attrition from HIV treatment programs in central Mozambique. METHODS We conducted a retrospective cohort study of adult, ART-naive, nonpregnant patients who initiated ART between January 2006 and June 2008 in the national HIV care program. Cox proportional hazards models were used to assess the association of patient volume, clinical staff burden, and pharmacy staff burden with attrition, adjusting for patient characteristics. RESULTS A total of 11,793 patients from 18 clinics were studied. After adjusting for patient characteristics, patients attending clinics with medium pharmacy staff burden [hazard ratio (HR) = 1.39 (95% CI: 1.07 to 1.80)] and high pharmacy staff burden [HR = 2.09 (95% CI: 1.50 to 2.91)] tended to have a higher risk of attrition (P value for trend: <0.001). Patients attending clinics with higher clinical staff burden did not have a statistically higher risk of attrition. Patients attending clinics with medium patient volume levels [HR = 1.45 (95% CI: 1.04 to 2.04)] and high patient volume levels [HR = 1.41 (95% CI: 1.04 to 1.92)] had a higher risk of attrition, but the trend test was not significant (P = 0.198). DISCUSSION Patients attending clinics with higher pharmacy staff burden had a higher risk of attrition. These results highlight a potential area within the health system where interventions could be applied to improve the retention of these patient populations.

Abstract
Background The growing caseload caused by patients with chronic life-long conditions leads to increased needs for health care providers and rising costs of health services, resulting in a heavy burden on health systems, populations and individuals. The professionalised health care for chronic patients common in high income countries is very labour-intensive and expensive. Moreover, the outcomes are often poor. In low-income countries, the scarce resources and the lack of quality and continuity of health care result in high health care expenditure and very poor health outcomes. The current proposals to improve care for chronic patients in low-income countries are still very much provider-centred. The aim of this paper is to show that present provider-centred models of chronic care are not adequate and to propose 'full self-management' as an alternative for low-income countries, facilitated by expert patient networks and smart phone technology. Discussion People with chronic life-long conditions need to 'rebalance' their life in order to combine the needs related to their chronic condition with other elements of their life. They have a crucial role in the management of their condition and the opportunity to gain knowledge and expertise in their condition and its management. Therefore, people with chronic life-long conditions should be empowered so that they become the centre of management of their condition. In full self-management, patients become the hub of management of their own care and take full responsibility for their condition, supported by peers, professionals and information and communication tools. We will elaborate on two current trends that can enhance the capacity for self-management and coping: the emergence of peer support and expert-patient networks and the development and distribution of smart phone technology both drastically expand the possibilities for full self-management. Conclusion Present provider-centred models of care for people with chronic life-long conditions are not adequate and we propose 'full self-management' as an alternative for low-income countries, supported by expert networks and smart phone technology.

Abstract
PURPOSE OF REVIEW Given the lack of evidence on how to best design and implement antiretroviral therapy (ART) scaling-up policies, operational research has seen a surge in interest. There is, however, little published information on the contribution of operational research in ART programs' implementation or in improvement of associated outcomes. The article focuses therefore on how operational research may contribute to such improvements and what the key enabling factors are for its integration into program frameworks. RECENT FINDINGS One of the most systematic operational research linked to a national ART program on the African continent was conducted in Cameroon between 2006 and 2010. Along with operational research carried out elsewhere in Africa, it helped demonstrate that a strategy of decentralizing HIV care can increase treatment coverage and improve early access to care, while maintaining good clinical outcomes. Multipartnership between local researchers, national authorities, healthcare professionals and the civil society is the key enabling factor for the relevance of operational research and the translation of its results into policy and practice. SUMMARY In spite of a dramatic increase in access to ART during recent years in low-income countries, the fight against HIV remains a failure in terms of the goal of breaking the pandemic dynamic. Operational research is needed more than ever to face this challenge.

Abstract
Background In South Africa, limited human resources are a major constraint to achieving universal antiretroviral therapy (ART) coverage. Many of the public-sector HIV clinics operating within tertiary facilities, that were the first to provide ART in the country, have reached maximum patient capacity. Decentralization or "down-referral" (wherein ART patients deemed stable on therapy are referred to their closest Primary Health Clinics (PHCs) for treatment follow-up) is being used as a possible alternative of ART delivery care. This cross-sectional qualitative study investigates attitudes towards down-referral of ART delivery care among patients currently receiving care in a centralized tertiary HIV clinic. Methods Ten focus group discussions (FGDs) with 76 participants were conducted in early 2008 amongst ART patients initiated and receiving care for more than 3 months in the tertiary HIV clinic study site. Eligible individuals were invited to participate in FGDs involving 6-9 participants, and lasting approximately 1-2 hours. A trained moderator used a discussion topic guide to investigate the main issues of interest including: advantages and disadvantages of down-referral, potential motivating factors and challenges of down-referral, assistance needs from the transferring clinic as well as from PHCs. Results Advantages include closeness to patients' homes, transport and time savings. However, patients favour a centralized service for the following reasons: less stigma, patients established relationship with the centralized clinic, and availability of ancillary services. Most FGDs felt that for down-referral to occur there needed to be training of nurses in patient-provider communication. Conclusion Despite acknowledging the down-referral advantages of close proximity and lower transport costs, many participants expressed concerns about lack of trained HIV clinical staff, negative patient interactions with nurses, limited confidentiality and stigma. There was consensus that training of nurses and improved health systems at the local clinics were needed if successful down-referral was to take place.

Abstract
Background Only about one-third of eligible HIV/AIDS patients receive anti-retroviral treatment (ART). Decentralizing treatment is crucial to wider and more equitable access, but key obstacles are a shortage of trained healthcare workers (HCW) and challenges integrating HIV/AIDS care with other primary care. This report describes the development of a guideline and training program (PALM PLUS) designed to integrate HIV/AIDS care with other primary care in Malawi. PALM PLUS was adapted from PALSA PLUS, developed in South Africa, and targets middle-cadre HCWs (clinical officers, nurses, and medical assistants). We adapted it to align with Malawi's national treatment protocols, more varied healthcare workforce, and weaker health system infrastructure. Methods/Design The international research team included the developers of the PALSA PLUS program, key Malawi-based team members and personnel from national and district level Ministry of Health (MoH), professional associations, and an international non-governmental organization. The PALSA PLUS guideline was extensively revised based on Malawi national disease-specific guidelines. Advice and input was sought from local clinical experts, including middle-cadre personnel, as well as Malawi MoH personnel and representatives of Malawian professional associations. Results An integrated guideline adapted to Malawian protocols for adults with respiratory conditions, HIV/AIDS, tuberculosis, and other primary care conditions was developed. The training program was adapted to Malawi's health system and district-level supervision structure. PALM PLUS is currently being piloted in a cluster-randomized trial in health centers in Malawi (ISRCTN47805230). Discussion The PALM PLUS guideline and training intervention targets primary care middle-cadre HCWs with the objective of improving HCW satisfaction and retention, and the quality of patient care. Successful adaptations are feasible, even across health systems as different as those of South Africa and Malawi.

Abstract
The United Nations millennium development goal of providing universal access to antiretroviral therapy (ART) for patients living with HIV/AIDS by 2010 is unachievable. Currently, four million people are receiving ART, of an estimated 13.7 million who need it. A major challenge to achieving this goal is the shortage of health care workers in low-income and low-resource areas of the world. Sub-Saharan African countries have 68% of the world's burden of illness from AIDS, yet have only 3% of health care workers worldwide. The shortage of health care providers is primarily caused by a national and international 'brain drain,' poor distribution of health care workers within countries, and health care worker burnout.Even though the millennium development goal to provide universal access to ART will not be met by 2010, it is imperative to continue to build on the momentum created by these humanitarian goals. The present literature review was written with the purpose of attracting research and policy attention toward evidence from small-scale projects in sub-Saharan Africa, which have been successful at increasing access to ART. Specifically, a primary-care model of ART delivery, which focuses on decentralization of services, task shifting and community involvement will be discussed. To improve the health care worker shortage in sub-Saharan Africa, the conventional model of health care delivery must be replaced with an innovative model that utilizes doctors, nurses and community members more effectively.

Abstract
Until now, we have all been desperately trying to run behind the HIV/AIDS epidemic and catch up with it, but despite all our efforts, the epidemic remains well ahead of us. In 2010, the antiretroviral treatment (ART) gap was about 60%, AIDS-related deaths were almost two million a year, and on top of these figures, for every one person started on ART, there were two new HIV infections. What is needed to change this situation is to think ahead of the epidemic in terms of the programmatic tasks we will be faced with and try to act boldly in trying to implement those tasks. From a programmatic perspective, we: a) highlight what needs to fundamentally change in our thinking and overall approach to the epidemic; and b) outline a number of key task areas for implementation and related operational research.

Abstract
Background Global health initiatives have enabled the scale up of antiretroviral treatment (ART) over recent years. The impact of HIV-specific funds and programmes on non-HIV-related health services and health systems in genera has been debated extensively. Drawing on evidence from Malawi and Ethiopia, this article analyses the effects of ART scale-up interventions on human resources policies, service delivery and general health outcomes, and explores how synergies can be maximized. Methods Data from Malawi and Ethiopia were compiled between 2004 and 2009 and between 2005 and 2009, respectively. We developed a conceptual health systems framework for the analysis. We used the major changes in human resources policies as an entry point to explore the wider health systems changes. Results In both countries, the need for an HIV response triggered an overhaul of human resources policies. As a result, the health workforce at health facility and community level was reinforced. The impact of this human resources trend was felt beyond the scale up of ART services; it also contributed to an overall increase in functional health facilities providing curative, mother and child health, and ART services. In addition to a significant increase in ART coverage, we observed a remarkable rise in user rates of non-HIV health services and an improvement in overall health outcomes. Conclusions Interventions aimed at the expansion of ART services and improvement of long-term retention of patients in ART care can have positive spill-over effects on the health system. The responses of Malawi and Ethiopia to their human resources crises was exceptional in many respects, and some of the lessons learnt can be useful in other contexts. The case studies show the feasibility of obtaining improved health outcomes beyond HIV through scaled-up ART interventions when these are part of a long-term, system-wide health plan supported by all decision makers and funders.

Abstract
In order to sustainably scale-up antiretroviral treatment (ART), South Africa needs to develop an efficient and effective implementation strategy, based on the best available scientific evidence. This article aims to bridge this knowledge gap first by describing the progress South Africa has made in the fight against HIV/AIDS in terms of virological efficacy, survival rates and retention in care, and second by identifying the potential remaining impediments to a durable and sustainable policy response to the epidemic. The study findings demonstrate that, despite favorable results in terms of virologic suppression, survival/mortality and retention in care, four challenges to a sustainable ART scale-up remain: first, the lack of integration of ART services into the general health system; second, the growing need for comprehensive HIV/AIDS care; third, the rising costs associated with the growing case load of people; and fourth, the crippling shortage in human resources for healthcare.

Abstract
OBJECTIVE To investigate whether PALSA PLUS, an on-site educational outreach programme of non-didactic, case based, iterative clinical education of staff, led by a trainer, can increase access to and comprehensiveness of care for patients with HIV/AIDS. DESIGN Cluster randomised trial. SETTING Public primary care clinics offering HIV/AIDS care, antiretroviral treatment (ART), tuberculosis care, and ambulatory primary care in Free State province, South Africa. PARTICIPANTS Fifteen clinics all implementing decentralisation and task shifting were randomised. The clinics cared for 400,000 general primary care patients and 10,136 patients in an HIV/AIDS/ART programme. There were 150 nurses. INTERVENTION On-site outreach education in eight clinics; no such education in seven (control). MAIN OUTCOME MEASURES Provision of co-trimoxazole prophylaxis among patients referred to the HIV/AIDS/ART programme, and detection of cases of tuberculosis among those in the programme. Proportion of patients in the programme enrolled through general primary care consultations. RESULTS Patients referred to the HIV/AIDS programme through general primary care at intervention clinics were more likely than those at control clinics to receive co-trimoxazole prophylaxis (41%, (2253/5523) v 32% (1340/4210); odds ratio 1.95, 95% confidence interval 1.11 to 3.40), and tuberculosis was more likely to be diagnosed among patients with HIV/AIDS/ART (7% (417/5793) v 6% (245/4343); 1.25, 1.01 to 1.55). Enrolment in the HIV/AIDS and ART programme through HIV testing in general primary care was not significantly increased (53% v 50%; 1.19, 0.51 to 2.77). Secondary outcomes were similar, except for weight gain, which was higher in the intervention group (2.3 kg v 1.9 kg, P<0.001). CONCLUSION Though outreach education is an effective and feasible strategy for improving comprehensiveness of care and wellbeing of patients with HIV/AIDS, there is no evidence that it increases access to the ART programme. It is now being widely implemented in South Africa. TRIAL REGISTRATION Current Controlled Trials ISRCTN 24820584.

Abstract
BACKGROUND Our intention was to analyze demographic and contextual factors associated with sexual risk taking among HIV-infected patients on antiretroviral treatment (ART) in Africa's largest informal urban settlement, Kibera in Nairobi, Kenya. METHODS We used a cross-sectional survey in a resource-poor, urban informal settlement in Nairobi; 515 consecutive adult patients on ART attending the African Medical and Research Foundation clinic in Kibera in Nairobi were included in the study. Interviewers used structured questionnaires covering socio-demographic characteristics, time on ART, number of sexual partners during the previous six months and consistency of condom use. RESULTS Twenty-eight percent of patients reported inconsistent condom use. Female patients were significantly more likely than men to report inconsistent condom use (aOR 3.03; 95% CI 1.60-5.72). Shorter time on ART was significantly associated with inconsistent condom use. Multiple sexual partners were more common among married men than among married women (adjusted OR 4.38; 95% CI 1.82-10.51). CONCLUSIONS Inconsistent condom use was especially common among women and patients who had recently started ART, i.e., when the risk of HIV transmission is higher. Having multiple partners was quite common, especially among married men, with the potential of creating sexual networks and an increased risk of HIV transmission. ART needs to be accompanied by other preventive interventions to reduce the risk of new HIV infections among sero-discordant couples and to increase overall community effectiveness.

Abstract
We describe the impact of an antiretroviral therapy program on human resource utilization and service delivery in a rural hospital in Monze, Zambia, using qualitative data. We assess project impact on staff capacity utilization, service delivery, and community perception of care. Increased workload resulted in fatigue, low staff morale, and exacerbated critical manpower shortages, but also an increase in users of antiretroviral therapy, improvement in hospital infrastructure and funding, and an overall community satisfaction with service delivery. Integrating HAART programs within existing hospital units and services may be a good alternative to increase overall efficiency.

Abstract
The government of India launched the free anti-retroviral therapy (ART) initiative in 2004 and the programme has since scaled up expansion in a phased manner. Programme authorities acknowledge problems in scale-up, yet discussions have been restricted to operational constraints, with little consideration for how local health system responses to HIV/AIDS influence the delivery of ART. This paper draws on the perspectives of key informants and people living with HIV (PLHIV) to compare delivery of ART in two ART centres in the States of Maharashtra and Andhra Pradesh at two distinct points of time. In 2005, data were collected through key informant interviews (KIIs) using interview guides and a survey of PLHIV using a semi-structured interview schedule. Differences were observed in the functioning and resources of the two centres, indicating different levels of preparedness which in turn influenced PLHIV's pathways in accessing ART. We examine these differences in the light of programme leadership, ownership and the roles of public, private and non-governmental organisation actors in HIV care. KIIs conducted during a follow-up visit in 2009 focused on changes in ART delivery. Many operational problems had been resolved; however, new challenges were emerging as a result of the increased patient load. An understanding of how ART programmes evolve within local health systems has bearing on future developments of the ART programme and must include a consideration of the wider socio-political environment within which HIV programmes are embedded.

Abstract
Background Although South Africa has the largest public-sector anti-retroviral treatment (ART) programme in the world, anti-retroviral coverage in adults was only 40.2% in 2008. However, longitudinal studies of who is accessing the South African public-sector ART programme are scarce. This study therefore had one main research question: who is accessing public-sector ART in the Free State Province, South Africa? The study aimed to extend the current literature by investigating, in a quantitative manner and using a longitudinal study design, the participants enrolled in the public-sector ART programme in the period 2004-2006 in the Free State Province of South Africa. Methods Differences in the demographic (age, sex, population group and marital status) socio-economic (education, income, neo-material indicators), geographic (travel costs, relocation for ART), and medical characteristics (CD4, viral load, time since first diagnosis, treatment status) among 912 patients enrolled in the Free State public-sector ART programme between 2004 and 2006 were assessed with one-way analysis of variance, Bonferroni post-hoc analysis, and cross tabulations with the chi square test. Results The patients accessing treatment tended to be female (71.1%) and unemployed (83.4%). However, although relatively poor, those most likely to access ART services were not the most impoverished patients. The proportion of female patients increased (P < 0.05) and their socio-economic situation improved between 2004 and 2006 (P < 0.05). The increasing mean transport cost (P < 0.05) to visit the facility is worrying, because this cost is an important barrier to ART uptake and adherence. Encouragingly, the study results revealed that the interval between the first HIV-positive diagnosis and ART initiation decreased steadily over time (P < 0.05). This was also reflected in the increasing baseline CD4 cell count at ART initiation (P < 0.05). Conclusions Our analysis showed significant changes in the demographic, socio-economic, geographic, and medical characteristics of the patients during the first three years of the programme. Knowledge of the characteristics of these patients can assist policy makers in developing measures to retain them in care. The information reported here can also be usefully applied to target patient groups that are currently not reached in the implementation of the ART programme.

Abstract
The South African public-sector antiretroviral treatment (ART) program has yielded promising early results. To extend and reinforce these preliminary findings, we undertook a detailed assessment of the clinical efficacy and outcomes over two years of ART. The primary objective was to assess the clinical outcomes and adverse effects of two years of ART, while identifying the possible effects of baseline health and patient characteristics. A secondary objective was to address the interplay between positive and negative outcomes (clinical benefits versus adverse effects) in terms of the patients' physical and emotional quality of life (QoL). Clinical outcome, baseline characteristics, health status, and physical and emotional QoL scores were determined from clinical files and interviews with 268 patients enrolled in the Free State ART program at three time points (6, 12, and 24 months of ART). Age, sex, education, and baseline health (CD4 cell count and viral load) were all independently associated with the ART outcome in the early stages of treatment, but their impact diminished as the treatment progressed. The number of patients classified as treatment successes increased over the first two years of ART, whereas the proportion of patients experiencing adverse effects diminished. Importantly, our findings show that ART had strong and stable positive effects on physical and emotional QoL. These favorable results demonstrate that a well-managed public-sector ART program can be very successful within a high-HIV-prevalence resource-limited setting. This finding emphasizes the need to adopt treatment scale-up as a key policy priority, while at the same time ensuring that the highest standards of healthcare provision are maintained. Healthcare services should also target vulnerable groups (males, less-educated patients, those with low baseline CD4 cell counts, and high baseline viral loads) who are most likely to experience treatment failure.

Abstract
The term 'scaling up' is now widely used in the international health literature, though it lacks an agreed definition. We review what is meant by scaling up in the context of changes in international health and development over the last decade. We argue that the notion of scaling up is primarily used to describe the ambition or process of expanding the coverage of health interventions, though the term has also referred to increasing the financial, human and capital resources required to expand coverage. We discuss four pertinent issues in scaling up the coverage of health interventions: the costs of scaling up coverage; constraints to scaling up; equity and quality concerns; and key service delivery issues when scaling up. We then review recent progress in scaling up the coverage of health interventions. This includes a considerable increase in the volume of aid, accompanied by numerous new health initiatives and financing mechanisms. There have also been improvements in health outcomes and some examples of successful large-scale programmes. Finally, we reflect on the importance of obtaining a better understanding of how to deliver priority health interventions at scale, the current emphasis on health system strengthening and the challenges of sustaining scaling up in the prevailing global economic environment.

Abstract
Operational research (OR) has been identified as a key component of the scaling-up of antiretroviral therapy provision in resource-limited settings. OR is usually defined through its concern for applied issues and the participation of local stakeholders. Who the stakeholders should be or what their participation entails has seldom been precisely defined, and there are variations among guidelines about the conditions of their participation in the research process. The scope, achievements and limits of stakeholders' participation is analyzed here, with reference to an OR project on care practices for AIDS patients at various levels and in various sectors of the health system in Burkina Faso. The overall objectives of the project were to ameliorate care practices and to reinforce the collaboration between caregivers in non-governmental organizations, public, private, faith and community-based facilities. A large number of stakeholders was involved in the advisory committee and the research team and participated in the research from formulation to dissemination. This helped define research questions that were relevant for each sector and facilitate the acceptance of the study in the field. Some disadvantages also appeared, such as an overly broad scope of the project, delays in implementation, difficulties in coordination and unequal involvement of team members. The experience analysed here shows that effective participation of stakeholders at all stages can make a difference to the relevance, quality and implementation of OR. There may, in addition, be an optimal level of stakeholders' participation, both in terms of the numbers and composition of the group, beyond which disadvantages become apparent.

Abstract
High levels of treatment adherence are crucial for the success of expanding ART treatment programs everywhere. Augmenting adherence through treatment supporters is one promising strategy. Most discussions focus on peers, especially members of PHA groups, for this purpose. Far less attention is given to family members and especially older age parents. Yet ART recipients often live with or nearby parents and other family members who are highly motivated to ensure the treatment's success. This study examines the extent that family members, especially parents, assist adherence in Thailand. Results indicate that most adult ART patients live with family members and over half live with or in the same locality as a parent. Family members, including parents, commonly remind ART patients to take medications, especially if coresident. Moreover, parents often remind patients to get resupplies and sometimes accompany them to appointments. Clearly close family members, including parents, should be explicitly incorporated into adherence augmentation programs and provided adequate information to facilitate their role as long-term adherence partners, not only in Thailand but wherever ART recipients are closely linked to family members through living and caregiving arrangements.

Abstract
Introduction South Africa has the largest HIV/AIDS epidemic of any country in the world. Case description National antiretroviral therapy (ART) policy is examined over the period of 1999 to 2008, which coincided with the government of President Thabo Mbeki and his Minister of Health, Dr Manto Tshabalala-Msimang. The movement towards a national ART programme in South Africa was an ambitious undertaking, the likes of which had not been contemplated before in public health in Africa. Discussion and evaluation One million AIDS-ill individuals were targeted to be enrolled in the ART programme by 2007/08. Fewer than 50% of eligible individuals were enrolled. This failure resulted from lack of political commitment and inadequate public health system capacity. The human and economic costs of this failure are large and sobering. Conclusions The total lost benefits of ART not reaching the people who need it are estimated at 3.8 million life years for the period, 2000 to 2005. The economic cost of those lost life years over this period has been estimated at more than US$15 billion.

Abstract
Hitherto, the story of HIV/AIDS in South Africa is, to a large extent, one of lost opportunities. Whereas the country has one of the worst epidemics in the world, consecutive national AIDS strategies have been repeatedly marked by failure over almost three decades. Understandably, South Africa's most recent HIV/AIDS policy, the HIV & AIDS and STI Strategic Plan for South Africa, 2007-2011 (NSP), has been greeted with general acclaim. However, what are its real prospects of success against the backdrop of the repeated failures of the past? The first objective of this review is to systematically identify the core reasons for past policy failures. Using a comprehensive analytical framework, this article presents a systematic review of the literature on postapartheid AIDS policy in South Africa. The analysis demonstrates that a complex interplay among the content, context, actors and process of AIDS policy created a gap between policy making and policy implementation, which rendered near-ideal AIDS policies ineffective. Secondly, we evaluate the chances of success of the current NSP by examining both the policy-making phase and the resulting policy document in light of the reasons for past policy failures. Our analysis shows that the NSP contains dynamic and comprehensive policy content, sensitive to the socio-economic and cultural dimensions of HIV/AIDS. However, many of the political actors that hampered treatment implementation in the past, and who deepened the gap between government and civil society, are still in office. Monetary and human resource shortages also create a policy context that is infertile for the implementation of a comprehensive HIV/AIDS strategy, as envisaged in the NSP. Finally, these health system restrictions have a clear negative impact on the process of policy implementation. Without the mobilization of people living with HIV/AIDS and their communities, the NSP will be ineffective in bridging the gap between policy intentions and policy implementation. The strength of this article lies in its systematic analysis of previous policy responses, as a basis for appraising current AIDS policy. Although such an approach tends to simplify the complexities of the actual policy environment, it nonetheless draws to the attention of policy participants the importance of and the complex interrelationships among the different dimensions of AIDS policy.
