Models of Community/Home-Based Care for People Living With HIV/AIDS in Southern Africa

Liberia adherence and loss-to-follow-up in HIV and AIDS care and treatment: A retrospective cohort of adolescents and adults from 2016-2019

Antiretroviral therapy (ART) is a lifesaving intervention for people living with HIV infection, reducing morbidity and mortality; it is likewise essential to reducing transmission. The "Treat all" strategy recommended by the World Health Organization has dramatically increased ART eligibility and improved access. However, retaining patients on ART has been a major challenge for many national programs in low- and middle-income settings, despite actionable local policies and ambitious targets. To estimate retention of patients along the HIV care cascade in Liberia, and identify factors associated with loss-to-follow-up (LTFU), death, and suboptimal treatment adherence, we conducted a nationwide retrospective cohort study utilizing facility and patient-level records. Patients aged ≥15 years, from 28 facilities who were first registered in HIV care from January 2016 -December 2017 were included. We used Cox proportional hazard models to explore associations between demographic and clinical factors and the outcomes of LTFU and death, and a multinomial logistic regression model to investigate factors associated with suboptimal treatment adherence. Among the 4185 records assessed, 27.4% (n = 1145) were males and the median age of the cohort was 37 (IQR: 30-45) years. At 24 months of follow-up, 41.8% (n = 1751) of patients were LTFU, 6.6% (n = 278) died, 0.5% (n = 21) stopped treatment, 3% (n = 127) transferred to another facility and 47.9% (n = 2008) were retained in care and treatment. The incidence of LTFU was 46.0 (95% CI: 40.8-51.6) per 100 person-years. Relative to patients at WHO clinical stage I at first treatment visit, patients at WHO clinical stage III [adjusted hazard ratio (aHR) 1.59, 95%CI: 1.21-2.09; p <0.001] or IV (aHR 2.41, 95%CI: 1.51-3.84; p <0.001) had increased risk of LTFU; whereas at registration, age category 35-44 (aHR 0.65, 95%CI: 0.44-0.98, p = 0.038) and 45 years and older (aHR 0.60, 95%CI: 0.39-0.93, p = 0.021) had a decreased risk. For death, patients assessed with WHO clinical stage II (aHR 2.35, 95%CI: 1.53-3.61, p<0.001), III (aHR 2.55, 95%CI: 1.75-3.71, p<0.001), and IV (aHR 4.21, 95%CI: 2.57-6.89, p<0.001) had an increased risk, while non-pregnant females (aHR 0.68, 95%CI: 0.51-0.92, p = 0.011) and pregnant females (aHR 0.42, 95%CI: 0.20-0.90, p = 0.026) had a decreased risk when compared to males. Suboptimal adherence was strongly associated with the experience of drug side effects-average adherence [adjusted odds ratio (aOR) 1.45, 95% CI: 1.06-1.99, p = 0.02) and poor adherence (aOR 1.75, 95%CI: 1.11-2.76, p = 0.016), and attending rural facility decreased the odds of average adherence (aOR 0.01, 95%CI: 0.01-0.03, p<0.001) and poor adherence (aOR 0.001, 95%CI: 0.0004-0.003, p<0.001). Loss-to-follow-up and poor adherence remain major challenges to achieving viral suppression targets in Liberia. Over two-fifths of patients engaged with the national HIV program are being lost to follow-up within 2 years of beginning care and treatment. WHO clinical stage III and IV were associated with LTFU while WHO clinical stage II, III and IV were associated with death. Suboptimal adherence was further associated with experience of drug side effects. Active support and close monitoring of patients who have signs of clinical progression and/or drug side effects could improve patient outcomes.

Approaches to integrating palliative care into African health systems: a qualitative systematic review

Africa is characterized by a high burden of disease and health system deficits, with an overwhelming and increasing demand for palliative care (PC). Yet only one African country is currently considered to have advanced integration of palliative care into medical services and generalized PC is said to be available in only a handful of others. The integration of PC into all levels of a health system has been called for to increase access to PC and to strengthen health systems. Contextually appropriate evidence to guide integration is vital yet limited. This qualitative systematic review analyses interventions to integrate PC into African health systems to provide insight into the 'how' of PC integration. Forty articles were identified, describing 51 different interventions. This study found that a variety of integration models are being applied, with limited best practices being evaluated and repeated in other contexts. Interventions typically focused on integrating specialized PC services into individual or multiple health facilities, with only a few examples of PC integrated at a population level. Four identified issues could either promote integration (by being present) or block integration (by their absence). These include the provision of PC at all levels of the health system alongside curative care; the development and presence of sustainable partnerships; health systems and workers that can support integration; and lastly, placing the client, their family and community at the centre of integration. These echo the broader literature on integration of health services generally. There is currently a strong suggestion that the integration of PC contributes to health system strengthening; however, this is not well evidenced in the literature and future interventions would benefit from placing health systems strengthening at the forefront, as well as situating their work within the context of integration of health services more generally.

Willingness by people living with HIV/AIDS to utilize HIV services provided by Village Health team workers in Kalungu district, central Uganda

BACKGROUND

Less than one quarter of people in need have access to HIV services in Uganda. This study assessed willingness of people living with HIV/AIDS (PLWHAs) to utilize HIV services provided by Village Health Teams (VHTs) in Kalungu district, central Uganda.

METHODS

A cross-sectional study conducted in two health facilities providing anti-retroviral therapy enrolled 312 PLWHAs. Pre-tested semi-structured questionnaires were administered to participants at household level. A forward fitting logistic regression model computed the predictors of willingness of PLWHAs to utilize services provided by VHTs.

RESULTS

Overall, 49% were willing to utilize HIV services provided by VHTs increasing to 75.6% if the VHT member was HIV positive. PLWHAs who resided in urban areas were more likely to utilize HIV services provided by VHTs (AOR 0.24, 95%CI 0.06-0.87). Barriers to utilizing HIV services provided by VHTs were: income level > 40 USD (AOR 6.43 95%CI 1.19-34.68), being a business person (AOR 8.71 95%CI 1.23-61.72), peasant (AOR 7.95 95%CI 1.37-46.19), lack of encouragement from: peers (AOR 6.33 95%CI 1.43-28.09), spouses (AOR 4.93 95%CI 1.23-19.82) and community leader (AOR 9.67 95%CI 3.35-27.92).

CONCLUSION

Social support could improve willingness by PLWHAs to utilize HIV services provided by VHTs for increased access to HIV services by PLWHA.

Health-promoting practices and the factors associated with self-reported poor health in caregivers of children orphaned by AIDS in southwest Uganda

Informal caregivers worldwide are faced with the dilemma of maintaining their health and meeting the caregiving demands of their loved ones. This study explores the health outcomes of caregiving, caregivers' health-promoting practices and the challenges to providing care among caregivers to children orphaned by AIDS in southwest Uganda. A descriptive design and interview questionnaires were used to collect data from 204 caregivers. The average age of the caregivers was 41.36 (±10.9) years and most of them (53%) were grandmothers to the orphans. The majority (65%) of the caregivers were caring for at least three orphans, had been in the caregiver role for more than five years (61%), and stated that their health had been negatively impacted by caregiving (61%). According to self-reports, the most common new health problems since taking up the caregiving role were chronic ill health (97%), social isolation (95%) and mental stress (92%). The health-promoting practices most often engaged in were eating a balanced diet (67%), seeking spiritual support (58%), and performing self-care activities (44%). The challenges to caregiving most often reported were poverty (88%) and a lack of time to seek personal medical care (59%). The predictors of self-reported poor health among the caregivers were stress (odds ratio [OR] = 3.43; p ≤ 0.01), caring for three or more orphans (OR = 2.19; p ≤ 0.01), female gender (OR = 1.77; p ≤ 0.01), and having spent more than five years as a caregiver to an orphan (OR = 1.35; p ≤ 0.01). The findings suggest that caregivers commonly experience poor health and their health-promoting practices are inadequate. There is a need for organised and formal health-promotion programmes for caregivers of children orphaned by AIDS, especially in rural areas of developing countries. Interventions for health promotion can be achieved through integrated programmes that provide health education, social services, respite from caregiving and counselling.

Reckoning HIV/AIDS care: A longitudinal study of community home-based caregivers and clients in Swaziland

The article is a descriptive case study of a community home-based care (CHBC) organisation in Swaziland that depicts the convergence of CHBC expansion with substantially improved health outcomes. Comprised of 993 care supporters who tend to 3 839 clients in 37 communities across southern Swaziland, Shiselweni Home-based Care (SHBC) is illustrative of many resource-limited communities throughout Africa that have mobilised, at varying degrees of formality, to address the individual and household suffering associated with HIV/AIDS. To better understand the potential significance of global and national health policy/programming reliance on community health workers (task shifting), we analysed longitudinal data on both care supporter and client cohorts from 2008 to 2013. Most CHBC studies report data from only one cohort. Foremost, our analysis demonstrated a dramatic decline (71.4%) among SHBC clients in overall mortality from 32.2% to 9.2% between 2008 and 2013. Although the study was not designed to establish statistical significance or causality between SHBC expansion and health impact, our findings detail a compelling convergence among CHBC, improved HIV health practices, and declines in client mortality. Our analysis indicated (1) the potential contributions of community health workers to individual and community wellbeing, (2) the challenges of task-shifting agendas, above all comprehensive support of community health workers/care supporters, and (3) the importance of data collection to monitor and strengthen the critical health services assigned to CHBC. Detailed study of CHBC operations and practices is helpful also for advancing government and donor HIV/AIDS strategies, especially with respect to health services decentralisation, in Swaziland and similarly profiled settings.

Experiences of collaboration, coordination and efficiency in the delivery of HIV/AIDS home-based care in Zimbabwe

The difficulties of achieving successful collaboration between stakeholders can lead to uncoordinated and fragmented outcomes for HIV/AIDS programming, which has consequences for the immediate health and livelihood security of the intended beneficiaries. This article examines the collaboration between local, national and international partner organisations in the delivery of and coordination of HIV/AIDS home-based care in Zimbabwe. The purpose of the research was to provide an external assessment of home-based care and to identify the problems that impede the delivery of health resources. Fieldwork was conducted between 2005 and 2008 at rural and peri-urban locations in Zimbabwe, using a combination of informal interviews, focus groups and participant observation. The findings suggest that the delivery of healthcare is impeded by problematic relationships between programme stakeholders-government, non-governmental and community-based. The outcome of poor service delivery is demonstrated to have a direct negative impact on the access to services, quality of care, and health outcomes for programme participants. The methods and findings of this research highlight the use of rapid ethnographic appraisal by social scientists to represent the interests of HIV/AIDS-affected populations in programme and policy design. This approach is crucial in situations such as in Zimbabwe where beneficiaries are less willing to voice their opinions for fear of being cut off from what little assistance is available in case what they say is viewed as uncooperative or noncompliant with a programme's objectives. The findings question the widely held assumption that multisectoral relationships are the most efficient way to deliver services.

Integration of community home based care programmes within national primary health care revitalisation strategies in Ethiopia, Malawi, South-Africa and Zambia: a comparative assessment

BACKGROUND

In 2008, the WHO facilitated the primary health care (PHC) revitalisation agenda. The purpose was to strengthen African health systems in order to address communicable and non-communicable diseases. Our aim was to assess the position of civil society-led community home based care programmes (CHBC), which serve the needs of patients with HIV, within this agenda. We examined how their roles and place in health systems evolved, and the prospects for these programmes in national policies and strategies to revitalise PHC, as new health care demands arise.

METHODS

The study was conducted in Ethiopia, Malawi, South Africa and Zambia and used an historical, comparative research design. We used purposive sampling in the selection of countries and case studies of CHBC programmes. Qualitative methods included semi-structured interviews, focus group discussions, service observation and community mapping exercises. Quantitative methods included questionnaire surveys.

RESULTS

The capacity of PHC services increased rapidly in the mid-to-late 2000s via CHBC programme facilitation of community mobilisation and participation in primary care services and the exceptional investments for HIV/AIDS. CHBC programmes diversified their services in response to the changing health and social care needs of patients on lifelong anti-retroviral therapy and there is a general trend to extend service delivery beyond HIV-infected patients. We observed similarities in the way the governments of South Africa, Malawi and Zambia are integrating CHBC programmes into PHC by making PHC facilities the focal point for management and state-paid community health workers responsible for the supervision of community-based activities. Contextual differences were found between Ethiopia, South Africa, Malawi and Zambia, whereby the policy direction of the latter two countries is to have in place structures and mechanisms that actively connect health and social welfare interventions from governmental and non-governmental actors.

CONCLUSIONS

Countries may differ in the means to integrate and co-ordinate government and civil society agencies but the net result is expanded PHC capacity. In a context of changing health care demands, CHBC programmes are a vital mechanism for the delivery of primary health and social welfare services.

Practicalities and challenges in re-orienting the health system in Zambia for treating chronic conditions

Background

The rapid evolution in disease burdens in low- and middle income countries is forcing policy makers to re-orient their health system towards a system which has the capability to simultaneously address infectious and non-communicable diseases. This paper draws on two different but overlapping studies which examined how actors in the Zambian health system are re-directing their policies, strategies and service structures to include the provision of health care for people with chronic conditions.

Methods

Study methods in both studies included semi-structured interviews with government health officials at national level, and governmental and non-governmental health practitioners operating from community-, primary health care to hospital facility level. Focus group discussions were conducted with staff, stakeholders and caregivers of programmes providing care and support at community- and household levels. Study settings included urban and rural sites.

Results

A series of adaptations transformed the HIV programme from an emergency response into the first large chronic care programme in the country. There are clear indications that the Zambian government is intending to expand this reach to patients with non-communicable diseases. Challenges to do this effectively include a lack of proper NCD prevalence data for planning, a concentration of technology and skills to detect and treat NCDs at secondary and tertiary levels in the health system and limited interest by donor agencies to support this transition.

Conclusion

The reorientation of Zambia’s health system is in full swing and uses the foundation of a decentralised health system and presence of local models for HIV chronic care which actively involve community partners, patients and their families. There are early warning signs which could cause this transition to stall, one of which is the financial capability to resource this process.

Development of non-profit organisations providing health and social services in rural South Africa: a three-year longitudinal study

Introduction

In an effort to increase understanding of formation of the community and home-based care economy in South Africa, we investigated the origin and development of non-profit organisations (NPOs) providing home- and community-based care for health and social services in a remote rural area of South Africa.

Methods

Over a three-year period (2010-12), we identified and tracked all NPOs providing health care and social services in Bushbuckridge sub-district through the use of local government records, snowballing techniques, and attendance at NPO networking meetings—recording both existing and new NPOs. NPO founders and managers were interviewed in face-to-face in-depth interviews, and their organisational records were reviewed.

Results

Forty-seven NPOs were formed prior to the study period, and 14 during the study period – six in 2010, six in 2011 and two in 2012, while four ceased operation, representing a 22% growth in the number of NPOs during the study period. Histories of NPOs showed a steady rise in the NPO formation over a 20-year period, from one (1991-1995) to 12 (1996-2000), 16 (2001-2005) and 24 (2006-2010) new organisations formed in each period. Furthermore, the histories of formation revealed three predominant milestones – loose association, formal formation and finally registration. Just over one quarter (28%) of NPOs emerged from a long-standing community based programme of ‘care groups’ of women. Founders of NPOs were mostly women (62%), with either a religious motivation or a nursing background, but occasionally had an entrepreneurial profile.

Conclusion

We observed rapid growth of the NPO sector providing community based health and social services. Women dominated the rural NPO sector, which is being seen as creating occupation and employment opportunities. The implications of this growth in the NPO sector providing community based health and social services needs to be further explored and suggests the need for greater coordination and possibly regulation.

A taxonomy for community-based care programs focused on HIV/AIDS prevention, treatment, and care in resource-poor settings

Community-based care (CBC) can increase access to key services for people affected by HIV/AIDS through the mobilization of community interests and resources and their integration with formal health structures. Yet, the lack of a systematic framework for analysis of CBC focused on HIV/AIDS impedes our ability to understand and study CBC programs. We sought to develop taxonomy of CBC programs focused on HIV/AIDS in resource-limited settings in an effort to understand their key characteristics, uncover any gaps in programming, and highlight the potential roles they play. Our review aimed to systematically identify key CBC programs focused on HIV/AIDS in resource-limited settings. We used both bibliographic database searches (Medline, CINAHL, and EMBASE) for peer-reviewed literature and internet-based searches for gray literature. Our search terms were ‘HIV’ or ‘AIDS’ and ‘community-based care’ or ‘CBC’. Two co-authors developed a descriptive taxonomy through an iterative, inductive process using the retrieved program information. We identified 21 CBC programs useful for developing taxonomy. Extensive variation was observed within each of the nine categories identified: region, vision, characteristics of target populations, program scope, program operations, funding models, human resources, sustainability, and monitoring and evaluation strategies. While additional research may still be needed to identify the conditions that lead to overall program success, our findings can help to inform our understanding of the various aspects of CBC programs and inform potential logic models for CBC programming in the context of HIV/AIDS in resource-limited settings. Importantly, the findings of the present study can be used to develop sustainable HIV/AIDS-service delivery programs in regions with health resource shortages.

Caregiver characteristics and economic cost of home-based care: a case study of Maun and Gumare villages in North West District, Botswana

The home-based care programme in Botswana was initiated partly to augment hospital or clinical care by reducing the healthcare costs associated with chronic illnesses such as HIV/AIDS. A number of studies have pointed to the psyco-social impacts of home based care, however there has been few attempts to quantify the direct and indirect costs associated with home based care. This study was carried out in the North West District of Botswana, which is noted for a relatively larger proportion of households with critically ill persons. The objectives of the study were to identify the characteristics of the caregivers and their patients; to estimate the direct and indirect costs of home-based care; and to estimate caregivers' willingness to pay for care services. Data was collected using a structured questionnaire addressed to 120 primary caregivers and analyzed using SPSS. The economic cost of caregiving was estimated using the replacement cost method. The annual value per caregiver was estimated at P31 320 (US$4818.46). The study also revealed that more often than not, women are involved in caregiving activities.

Understanding the linkages between informal and formal care for people living with HIV in sub-Saharan Africa

In response to the human resource challenges facing African health systems, there is increasing involvement of informal care providers in HIV care. Through social and institutional interactions that occur in the delivery of HIV care, linkages between formal and informal systems of care often emerge. Based on a review of studies documenting the relationships between formal and informal HIV care in sub-Saharan Africa, we suggest that linkages can be conceptualised as either 'actor-oriented' or 'systems-oriented'. Studies adopting an actor-oriented focus examine hierarchical working relationships and communication practices among health systems actors, while studies focusing on systems-oriented linkages document the presence, absence or impact of formal inter-institutional partnership agreements. For linkages to be effective, the institutional frameworks within which linkages are formalised, as well as the ground-level interactions of those engaged in care, ought to be considered. However, to date, both actor- and system-oriented linkages appear to be poorly utilised by policy makers to improve HIV care. We suggest that linkages between formal and informal systems of care be considered across health systems, including governance, human resources, health information and service delivery in order to improve access to HIV services, enable knowledge transfer and strengthen health systems.

Does social support in addition to ART make a difference? Comparison of households with TASO and MOH PLWHA in Central Uganda

Social support in addition to antiretroviral therapy (ART) has been indicated to be beneficial to person living with HIV/AIDS (PLWHA) and their families, but very few ART service providers go beyond ART. This study investigates whether receipt of social support in addition to ART for PLWHA makes the households that they reside in better off than households that have PLWHA but are without social support. The analysis uses data comprising of 450 households, which is a sub-sample from the 2010/2011 Centre for Health Economics Ugandan HIV Survey, a cross-sectional survey of 596 households that was undertaken in Uganda. Data were collected from households of clients that obtained ART from two major ART service providers in Central Uganda; The AIDS Support Organisation (TASO) and Ministry of Health (MOH), Uganda. Probit models and ordinary least squares regressions are employed to compare outcomes for individuals from households with a TASO or MOH client. Outcomes for individuals in households with a TASO PLWHA are hypothesised to be superior to those from households with an MOH PLWHA given that the benefits from social support accrue not only to the PLWHA but also to the household and communities they belong to. The results confirm that individuals from a household with a TASO PLWHA are better off in terms of physical health outcomes including better productivity as non-wage labour hours and having more cash in hand and having savings. The findings highlight the importance of additional support to HIV/AIDS clients and have implications for supplementation of ART service provision with other services to maximise the benefits from ART in resource constrained countries like Uganda.

What is the impact of home-based HIV counseling and testing on the clinical status of newly enrolled adults in a large HIV care program in Western Kenya?

BACKGROUND

This article describes the effect point of entry into the human immunodeficiency virus (HIV) care program had on the clinical status of adults presenting for the first time to USAID-AMPATH (US Agency for International Development-Academic Model Providing Access to Healthcare) Partnership clinics for HIV care.

METHODS

All patients aged ≥ 14 years enrolled between August 2008 and April 2010 were included. Points of entry to USAID-AMPATH clinics were home-based counseling and testing (HBCT), provider-initiated testing and counseling (PITC), HIV testing in the tuberculosis clinic, and voluntary counseling and testing (VCT). Tests for trend were calculated, and multivariable logistic regression was used to compare the effect of HBCT versus other points of entry on primary outcomes controlling for age and sex.

RESULTS

There were 19,552 eligible individuals. Of these, 946 tested in HBCT, 10,261 in VCT, 8073 in PITC, and 272 in the tuberculosis clinic. The median (interquartile range) enrollment CD4 cell counts among those who tested HIV positive was 323 (194-491), 217 (87-404), 190 (70-371), and 136 cells/mm(3) (59-266) for HBCT, VCT, PITC, and the tuberculosis clinic, respectively (P < .001). Compared with those patients whose HIV infection was diagnosed in the tuberculosis clinic, those who tested positive in HBCT were, controlling for age and sex, less likely to have to have World Health Organization stage III or IV HIV infection at enrollment (adjusted odds ratio [AOR], 0.04; 95% confidence interval [CI], .03-.06), less likely to enroll with a CD4 cell count of <200 cells/mm(3) (AOR, 0.20; 95% CI, .14-.28), and less likely to enroll into care with a chief complaint (AOR, 0.08; 95% CI, .05-.12).

CONCLUSIONS

HBCT is effective at getting HIV-infected persons enrolled in HIV care before they become ill.

Will universal access to antiretroviral therapy ever be possible? The health care worker challenge

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.

Estimating the cost of care giving on caregivers for people living with HIV and AIDS in Botswana: a cross-sectional study

Background

Community home-based care is the Botswana Government's preferred means of providing care for people living with HIV (PLHIV). However, primary (family members) or volunteer (community members) caregivers experience poverty, are socially isolated, endure stigma and psychological distress, and lack basic care-giving education. Community home-based care also imposes considerable costs on patients, their caregivers and families in terms of time, effort and commitment. An analysis of the costs incurred by caregivers in providing care to PLHIV will assist health and social care decision makers in planning the most appropriate ways to meet future service needs of PLHIV and their caregivers.

Methods

This study estimated the cost incurred in providing care for PLHIV through a stratified sample of 169 primary and volunteer caregivers drawn from eight community home-based care groups in four health districts in Botswana.

Results

The results show that the mean of the total monthly cost (explicit and indirect costs) incurred by the caregivers was $(90.45 ± 9.08) while the mean explicit cost of care giving was $(65.22 ± 7.82). This mean of the total monthly cost is about one and a half times the caregivers' mean monthly income of $66.00 (± 5.98) and more than six times the Government of Botswana's financial support to the caregivers. In addition, the cost incurred per visit by the caregivers was $15.26, while the total expenditure incurred per client or family in a month was $184.17.

Conclusions

The study, therefore, concludes that as the cost of providing care services to PLHIV is very high, the Government of Botswana should substantially increase the allowances paid to caregivers and the support it provides for the families of the clients. The overall costs for such a programme would be quite low compared with the huge sum of money budgeted each year for health care and for HIV and AIDS.

Delivering comprehensive home-based care programmes for HIV: a review of lessons learned and challenges ahead in the era of antiretroviral therapy

Home-based care (HBC) programmes in low- and middle-income countries have evolved over the course of the past two decades in response to the HIV epidemic and wider availability of antiretroviral therapy (ART). Evidence is emerging from small-scale and well-resourced studies that ART delivery can be effectively incorporated within HBC programmes. However, before this approach can be expanded, it is necessary to consider the lessons learned from implementing routine HBC programmes and to assess what conditions are required for their roll-out in the context of ART provision. In this paper, we review the literature on existing HBC programmes and consider the arguments for their expansion in the context of scaling up ART delivery. We develop a framework that draws on the underlying rationale for HBC and incorporates lessons learned from community health worker programmes. We then apply this framework to assess whether the necessary conditions are in place to effectively scale up HBC programmes in the ART era. We show that the most effective HBC programmes incorporate ongoing support, training and remuneration for their workers; are integrated into existing health systems; and involve local communities from the outset in programme planning and delivery. Although considerable commitment has so far been demonstrated to delivering comprehensive HBC programmes, their effectiveness is often hindered by weak linkages with other HIV services. Top-down donor policies and a lack of sustainable and consistent funding strategies represent a formidable threat to these programmes in the long term. The benefits of HBC programmes that incorporate ART care are unlikely to be replicated on a larger scale unless donors and policymakers address issues related to human resources, health service linkages and community preparedness. Innovative and sustainable funding policies are needed to support HBC programmes if they are to effectively complement national ART programmes in the long term.
