Integration of HIV/AIDS services into African primary health care: lessons learned for health system strengthening in Mozambique - a case study

Forecasting the effect of HIV-targeted interventions on the age distribution of people with HIV in Kenya

OBJECTIVES

To provide accurate forecasts of the age distribution of people with HIV (PWH) in Kenya from 2025 to 2040.

DESIGN

Development of a compartmental model of HIV in Kenya, calibrated to historical estimates of HIV epidemiology.

METHODS

We forecasted changes in population size and age distribution of new HIV infections and PWH under the status quo and under scale-up of HIV services.

RESULTS

Without scale-up, new HIV infections were forecasted to fall from 34 000 (28 000-41 000) in 2,025 to 29 000 (15 000-57 000) in 2,040; the percentage of new infections occurring among persons over 30 increased from 33% (20-50%) to 40% (24-62%). The median age of PWH increased from 39 years (38-40) in 2025 to 43 years (39-46) in 2040, and the percentage of PWH over age 50 increased from 26% (23-29%) to 34% (26-43%). Under the full intervention scenario, new infections were forecasted to fall to 6,000 (3,000-12 000) in 2,040. The percentage of new infections occurring in people over age 30 increased to 52% (34-71%) in 2,040, and there was an additional shift in the age structure of PWH [forecasted median age of 46 (43-48) and 40% (33-47%) over age 50].

CONCLUSION

PWH in Kenya are forecasted to age over the next 15 years; improvements to the HIV care continuum are expected to contribute to the growing proportion of older PWH.

What may encourage or deter health services utilization by people living with or at the risk of HIV/AIDS in special health centers? Qualitative evidence from a stigmatized community

BACKGROUND

Behavioral Diseases Counseling Centers (BDCCs) and Vulnerable Women's Counseling Centers (VWCCs) in Iran are the main peripheral centers that offer educational, counseling, diagnostic, preventive, curative and protective services to individuals living with or at high risk of contracting HIV/AIDS and female sex workers respectively. Due to the social stigma surrounding HIV in Iran, this study aims to identify the factors that may hinder or encourage HIV/AIDS patients and women with risky sexual behaviors from visiting these centers.

METHODS

Conducted in 2023, this qualitative study involved individuals visiting BDCCs and VWCCs in two western provinces of Iran, Ilam and Kermanshah. The study participants included 21 health staff members working in BDCCs and VWCCs and 20 HIV/AIDS patients and vulnerable women with unsafe sexual behaviors referring to these centers. Purposive, snowball and maximum variation sampling techniques were applied to interview the participants. Interviews were conducted between January 5th and May 21st, 2023, using a semi-structure guideline. Interviews were transcribed and content analysis approach was applied to analyze data using MAXQDA20 software.

RESULTS

According to the findings, the barriers and facilitators of visiting specialized centers for HIV/AIDS patients and vulnerable women were categorized into three main categories, 10 subcategories and 35 sub-subcategories including: Medical and operational processes (4 subcategories and 12 sub-subcategories), mutual interactions between the personnel and visitors (people living with and at the risk of getting HIV/AIDS) (3 subcategory and 13 sub-subcategories), and physical characteristics of the centers (3 subcategories and 10 sub-subcategories).

CONCLUSIONS

To improve the performance of BDCCs and VWCCs and encourage people living with and at the risk of contracting HIV/AIDS to visit these centers regularly, health policy makers should consider modifying clinical processes, physical features, personnel behaviors and visitors' concerns raised by the interviewees and the issues identified in this study.

Scaling-up and scaling-out the Systems Analysis and Improvement Approach to optimize the hypertension diagnosis and care cascade for HIV infected individuals (SCALE SAIA-HTN): a stepped-wedge cluster randomized trial

BACKGROUND

Undiagnosed and untreated hypertension is a main driver of cardiovascular disease and disproportionately affects persons living with HIV (PLHIV) in low- and middle-income countries. Across sub-Saharan Africa, guideline application to screen and manage hypertension among PLHIV is inconsistent due to poor service readiness, low health worker motivation, and limited integration of hypertension screening and management within HIV care services. In Mozambique, where the adult HIV prevalence is over 13%, an estimated 39% of adults have hypertension. As the only scaled chronic care service in the county, the HIV treatment platform presents an opportunity to standardize and scale hypertension care services. Low-cost, multi-component systems-level strategies such as the Systems Analysis and Improvement Approach (SAIA) have been found effective at integrating hypertension and HIV services to improve the effectiveness of hypertension care delivery for PLHIV, reduce drop-offs in care, and improve service quality. To build off lessons learned from a recently completed cluster randomized trial (SAIA-HTN) and establish a robust evidence base on the effectiveness of SAIA at scale, we evaluated a scaled-delivery model of SAIA (SCALE SAIA-HTN) using existing district health management structures to facilitate SAIA across six districts of Maputo Province, Mozambique.

METHODS

This study employs a stepped-wedge design with randomization at the district level. The SAIA strategy will be "scaled up" with delivery by district health supervisors (rather than research staff) and will be "scaled out" via expansion to Southern Mozambique, to 18 facilities across six districts in Maputo Province. SCALE SAIA-HTN will be introduced over three, 9-month waves of intensive intervention, where technical support will be provided to facilities and district managers by study team members from the Mozambican National Institute of Health. Our evaluation of SCALE SAIA-HTN will be guided by the RE-AIM framework and will seek to estimate the budget impact from the payer's perspective.

DISCUSSION

SAIA packages user-friendly systems engineering tools to support decision-making by frontline health workers and to identify low-cost, contextually relevant improvement strategies. By integrating SAIA delivery into routine management structures, this pragmatic trial will determine an effective strategy for national scale-up and inform program planning.

Post-intervention perceptions on the antiretroviral therapy community group model in Trans Nzoia County, Kenya

Introduction

the increasing number of people receiving antiretroviral therapy (ART) in sub-Saharan Africa has stressed already overburdened health systems. A care model utilizing community-based peer-groups (ART Co-ops) facilitated by community health workers (CHW) was implemented (2016-2018) to address these challenges. In 2018, a post-intervention study assessed perceptions of the intervention.

Methods

forty participants were engaged in focus group discussions consisting of ART Co-op clients, study staff, and health care providers from Kitale HIV clinic. Data were analyzed thematically for content on the intervention, challenges, and recommendations for improvement.

Results

all participants liked the intervention. However, some reported traveling long distances to attend ART Co-op meetings and experiencing stigma with ART Co-ops participation. The ART Co-op inclusion criteria were considered appropriate; however, additional outreach to deliberately include spouses living with HIV, the disabled, the poor, and HIV pregnant women was recommended. Participants liked CHW-directed quarterly group meetings which included ART distribution, adherence review, and illness identification. The inability of the CHW to provide full clinical care, inconvenient meeting venues, poor timekeeping, and non-attendance behaviors were noted as issues. Participants indicated that program continuation, regular CHW training, rotating meetings at group members´ homes, training ART Co-ops leaders to assume CHW tasks, use of pill diaries to check adherence, nutritional support, and economically empowering members through income generation projects would be beneficial.

Conclusion

the intervention was viewed positively by both clinic staff and clients. They identified specific challenges and generated actionable key considerations to improve access and acceptability of the community-based model of care.

The HIV/AIDS responses pre and during the COVID-19 pandemic in sub-Saharan Africa: A basis for sustainable health system strengthening post-COVID-19

In May 2023, the World Health Organization announced that COVID-19 was no longer a global emergency. The impact of COVID-19 on the provision of HIV/AIDS services was not that severe due to the reprogramming of key resources. For health systems in sub-Saharan Africa to become resilient to future pandemics, lessons should be learned from the successful HIV/AIDS response in the region, and how the HIV/AIDS services were successfully adapted to the COVID-19 pandemic. In this article, we reviewed the 6 World Health Organization health system building blocks on how the best practices from the provision of HIV/AIDS services and the services' response to the COVID-19 pandemic can be used as a basis for restoring and strengthening health systems to offer universal access to quality essential health services. The success of the leadership and governance for universal access to anti-retroviral therapy can be a blueprint for the realization of universal health coverage. Significant efficiencies that resulted in the reduction in anti-retroviral therapy costs can be leveraged to ensure cheaper essential drugs while differentiated service delivery models can be used to improve health service accessibility. New technologies that have proven to be successful in HIV/AIDS care can also be used in the care of other diseases, including disease outbreaks. The strong health information systems developed for HIV programs can be used as a foundation for developing health information systems for the whole health sector while the healthcare professionals trained for the provision of HIV/AIDS services can be trained to provide services for a variety of other conditions.

Knowledge and perceptions of primary healthcare providers towards integration of antiretroviral therapy (ART) services at departmental levels at selected health facilities Lira district, Uganda

BACKGROUND

Investigations conducted among healthcare providers to assess their knowledge and perceptions towards the integration of anti-retroviral therapy (ART) related services in Sub-Saharan Africa are limited. This study explored the knowledge and perceptions of primary healthcare providers towards the integration of ART management services at departmental levels in health facilities in Lira district.

METHODS

We conducted a descriptive cross-sectional survey that employed qualitative methods of data collection in four selected health facilities in Lira district between January and February 2022. The study involved in-depth interviews with key informants and focus group discussions. The study population consisted exclusively of primary healthcare providers; however, those who were not full-time employees of the participating health facilities were excluded. We used thematic content analysis.

RESULTS

A significant proportion of staff (especially those who are not directly involved in ART) still lack full knowledge of ART services integration. There was generally a positive perception, with some suggesting ART integration can minimize stigma and discrimination. The potential barriers to integration included limited knowledge and skills for providing comprehensive ART services, insufficient staffing and space, funding gaps, and inadequate drug supplies, coupled with increased workload due to enlarged clientele.

CONCLUSION

Whereas healthcare workers are generally knowledgeable about ART integration, but their knowledge was limited to partial integration. The participants had a basic understanding of ART services being provided by different health facilities. Furthermore, participants viewed integration as critical, but it should be implemented in conjunction with ART management training. Given that respondents reported a lack of infrastructure, increased workload, and understaffing, additional investments in staff recruitment, motivation through training and incentives, and other means are needed if ART integration is to be implemented.

Integrating HIV and substance misuse services: a person-centred approach grounded in human rights

Integrating HIV-related care with treatment for substance use disorder provides an opportunity to better meet the needs of people living with these conditions. People with substance use disorder are rendered especially vulnerable by prevailing policies, structural inequalities, and stigmatisation. In this Series paper we analyse existing literature and empirical evidence from scoping reviews on integration designs for the treatment of HIV and substance use disorder, to understand barriers to and facilitators of care integration and to map ways forward. We discuss how approaches to integration address two core gaps in current models: a failure to consider human rights when incorporating the perspectives of people living with HIV and people who use drugs, and a failure to reflect critically on structural factors that determine risk, vulnerability, health-care seeking, and health equity. We argue that successful integration requires a person-centred approach, which is grounded in human rights, treats both concerns holistically, and reconnects with underlying social, economic, and political inequalities.

Readiness of Mozambique Health Facilities to Address Undernutrition and Diarrhea in Children under Five: Indicators from 2018 and 2021 Survey Data

The World Health Organization’s systems framework shows that service delivery is key to addressing pressing health needs. Inadequate healthcare and the lack of healthcare services are factors associated with undernutrition and diarrhea in children under five, two health conditions with high morbi-mortality rates in Mozambique. The aim of the analysis was to determine the readiness score of nutrition and diarrhea services for children under five and the influence of malaria and HIV (Human Immunodeficiency Virus) service readiness on the readiness of these two services. A total of 1644 public health facilities in Mozambique were included from the 2018 Service Availability and Readiness Assessment. Additionally, a cross-sectional study was conducted to determine the availability and readiness scores of nutrition services in 2021 in five referral health facilities. The availability of nutrition and diarrhea services for children is low in Mozambique, with both scoring below 75%. Major unavailability was observed for human resources, guidelines, and training dimensions. Diarrhea (median (IQ): 72.2% (66.7 to 83.3)) and nutrition service readiness (median (IQ): 57.1% (52.4 to 57.1)) scores were significantly different (p < 0.001), while it is desirable for both services to be comprehensively ready. Nutrition services are positively associated with diarrhea service readiness and both services are associated with malaria and HIV service readiness (p < 0.05). None of the health facilities had all tracer items available and none of the facilities were considered ready (100%). There is a persisting need to invest comprehensively in readiness dimensions, within and across child health services.

Health-care provision and policy for non-alcoholic fatty liver disease in sub-Saharan Africa

Sub-Saharan Africa, which has a population of more than 1 billion people, carries 24% of the global burden of disease and spends the least on health care of any region, relying heavily on international development assistance to deliver health care for HIV, tuberculosis, and malaria. The demographic and epidemiological transitions occurring in sub-Saharan Africa, with rising prevalences of obesity and diabetes, enhance the risk of non-alcoholic fatty liver disease (NAFLD), yet this remains an unrecognised complication of metabolic syndrome. There are no guidance documents on NAFLD from sub-Saharan Africa, and non-communicable disease (NCD) guidance documents do not include the associated burden of fatty liver disease. Combating the health and socioeconomic burden of NAFLD requires an integrated liver health approach, with task-shifting to primary health care. Using clear guidance documents to link education and management of HIV, viral hepatitis, NAFLD, and associated NCDs is also crucial to an integrated approach to infectious diseases and NCDs, which requires targeted funding from both governments and international development agencies.

Evaluation of the partnership between international non-governmental organizations and the State in the health sector in Mozambique

Introduction

Mozambique is one of the poorest nations in the world and its health budget is heavily dependent on external funding. Increasingly, donors prefer to direct their funds through international non-governmental organizations instead of direct donations to the State budget. In the current climate of increased emphasis on health system strengthening, a strong and stable partnership between government and international non-governmental organizations is pivotal for health system strengthening in Mozambique.

Methods

the study evaluates the current partnership through a standardized survey to healthcare workers employed by international non-governmental organizations in health (INGO, private) and the ministry of health (MOH, public). Results of the survey have been analyzed only descriptively and no statistical evaluations have been performed.

Results

out of the valid 109 responses obtained 55.1% were from MOH cadres and 45.0% from INGO cadres. Most have been in the health sector for more than 5 years. Most of the respondents recognize that INGOs assist the government in strengthening the health system (71.6%), see the internal brain drain to INGOs and salary scale difference as major problems (70.6% and 78.0%); 87.2% reported that the coordination between INGOs and government needs to be improved. MOH cadres perceived the migration of cadres to INGOs and the need for improving coordination as major issues more acutely than their INGO counterparts (80.0% vs. 59.2% and 88.3% vs. 85.7% respectively). INGOs were perceived to offer better quality health services by 51.4% of respondents (of these 69.4% were INGO respondents). The quality of health services was alike between INGOs and MOH for 33% of the respondents.

Conclusion

through the various efforts outlined the MOH and INGOs are moving towards an environment of mutual accountability, joint planning and coordination as well as harmonization of activities; but there are still challenges to be addressed. Prioritization and increased funding of the planning unit and planning and cooperation directorate as well as strategies for workforce retention are urgently needed.

Quality of antiretroviral therapy services in Ghana: Implications for the HIV response in resource-constrained settings

Objective

Number of People Living with Human Immune-deficiency Virus in Ghana is over 300,000 and unmet need for antiretroviral therapy is approximately 60%. This study sought to determine the quality of antiretroviral therapy services in selected ART sites in Ghana using the input-process-outcome approach.

Methods

This is a descriptive cross-sectional case study that employed modified normative evaluation to assess quality of antiretroviral therapy services in the Oti and Volta regions of Ghana among People Living with HIV (n = 384) and healthcare providers (n = 16). The study was conducted from 11 March to 9 May 2019.

Results

Resources for managing HIV clients were largely available with the exception of viral load machines, reagents for CD4 counts, and antifungals such as Fluconazole and Cotrimoxazole. Patients enrolled on antiretroviral therapy within 2 weeks was 71% and clients retained in care within 2 weeks of enrolment was 90%. Approximately 26% of enrolled clients recorded viral load suppression; 33% of People Living with HIV who were not insured with the National Health Insurance Scheme paid for some antiretrovirals and cotrimoxazole. Adherence to ART and Cotrimoxazole were 95% and 88%, respectively, using pill count on their last three visits. Time spent with clinical team was among the worst rated (mean = 2.98, standard deviation = 0.54) quality indicators by patients contrary to interpersonal relationship with health provider which was among the best rated (mean = 3.25, standard deviation = 0.41) indicators.

Conclusion

Observed quality care gaps could potentially reverse gains made in HIV prevention and control in Ghana if not addressed timely; an important value addition of this study is the novel application of input-process-outcome approach in the context of antiretroviral therapy services in Ghana. There is also the need for policy dialogue on inclusion of medications for prophylaxis in antiretroviral therapy on the National Health Insurance Scheme to promote adherence and retention.

Program sustainability post PEPFAR direct service support in the Western Cape, South Africa

BACKGROUND

Public health practitioners have little guidance around how to plan for the sustainability of donor sponsored programs after the donor withdraws. The literature is broad and provides no consensus on a definition of sustainability. This study used a mixed-methods methodology to assess program sustainability factors to inform donor-funded programs.

METHODS

This study examined 61 health facilities in the Western Cape, South Africa, supported by four PEPFAR-funded non-governmental organizations from 2007 to 2012. Retention in care (RIC) was used to determine health facility performance. Sustainability was measured by comparing RIC during PEPFAR direct service (20072012), to RIC in the post PEPFAR period (2013 to 2015). Forty-three semi-structured in-depth interviews were conducted with key informants. The qualitative data were used to examine how predictor variables were operationalized at a health facility and NGO level.

RESULTS

Our qualitative results suggest the following lessons for the sustainability of future programs: Sufficient and stable resources (i.e., financial, human resources, technical expertise, equipment, physical space)Investment in organizations that understand the local context and have strong relationships with local government.Strong leadership at a health facility levelJoint planning/coordination and formalized skill transferLocal positive perceived value of the programPartnerships.

CONCLUSION

Sustainability is complex, context dependent, and is reliant on various processes and outcomes. This study suggests additional health facility and community level staff should be employed in the health system to ensure RIC sustainability. Sustainability requires joint donor coordination with experienced local organizations with strong managers before during and after program implementation. If the program is as large as the South African HIV effort some dedicated additional resources in the long term would be required.

HIV-associated tuberculosis

Tuberculosis (TB) remains a leading cause of morbidity and mortality among people living with HIV. HIV-associated TB disproportionally affects African countries, particularly vulnerable groups at risk for both TB and HIV. Currently available TB diagnostics perform poorly in people living with HIV; however, new diagnostics such as Xpert Ultra and lateral flow urine lipoarabinomannan assays can greatly facilitate diagnosis of TB in people living with HIV. TB preventive treatment has been underutilized despite its proven benefits independent of antiretroviral therapy (ART). Shorter regimens using rifapentine can support increased availability and scale-up. Mortality is high in people with HIV-associated TB, and timely initiation of ART is critical. Programs should provide decentralized and integrated TB and HIV care in settings with high burden of both diseases to improve access to services that diagnose TB and HIV as early as possible. The new prevention and diagnosis tools recently recommended by WHO offer an immense opportunity to advance our fight against HIV-associated TB. They should be made widely available and scaled up rapidly supported by adequate funding with robust monitoring of the uptake to advance global TB elimination.

Uganda's "EID Systems Strengthening" model produces significant gains in testing, linkage, and retention of HIV-exposed and infected infants: An impact evaluation

Introduction

A review of Uganda’s HIV Early Infant Diagnosis (EID) program in 2010 revealed poor retention outcomes for HIV-exposed infants (HEI) after testing. The review informed development of the ‘EID Systems Strengthening’ model: a set of integrated initiatives at health facilities to improve testing, retention, and clinical care of HIV-exposed and infected infants. The program model was piloted at several facilities and later scaled countrywide. This mixed-methods study evaluates the program’s impact and assesses its implementation.

Methods

We conducted a retrospective cohort study at 12 health facilities in Uganda, comprising all HEI tested by DNA PCR from June 2011 to May 2014 (n = 707). Cohort data were collected manually at the health facilities and analyzed. To assess impact, retention outcomes were statistically compared to the baseline study’s cohort outcomes. We conducted a cross-sectional qualitative assessment of program implementation through 1) structured clinic observation and 2) key informant interviews with health workers, district officials, NGO technical managers, and EID trainers (n = 51).

Results

The evaluation cohort comprised 707 HEI (67 HIV+). The baseline study cohort contained 1268 HEI (244 HIV+). Among infants testing HIV+, retention in care at an ART clinic increased from 23% (57/244) to 66% (44/67) (p < .0001). Initiation of HIV+ infants on ART increased from 36% (27/75) to 92% (46/50) (p < .0001). HEI receiving 1st PCR results increased from 57% (718/1268) to 73% (518/707) (p < .0001). Among breastfeeding HEI with negative 1st PCR, 55% (192/352) received a confirmatory PCR test, a substantial increase from baseline period. Testing coverage improved significantly: HIV+ pregnant women who brought their infants for testing after birth increased from 18% (67/367) to 52% (175/334) (p < .0001). HEI were tested younger: mean age at DBS test decreased from 6.96 to 4.21 months (p < .0001). Clinical care for HEI was provided more consistently. Implementation fidelity was strong for most program components. The strongest contributory interventions were establishment of ‘EID Care Points’, integration of clinical care, longitudinal patient tracking, and regular health worker mentorship. Gaps included limited follow up of lost infants, inconsistent buy-in/ownership of health facility management, and challenges sustaining health worker motivation.

Discussion

Uganda’s ‘EID Systems Strengthening’ model has produced significant gains in testing and retention of HEI and HIV+ infants, yet the country still faces major challenges. The 3 core concepts of Uganda’s model are applicable to any country: establish a central service point for HEI, equip it to provide high-quality care and tracking, and develop systems to link HEI to the service point. Uganda’s experience has shown the importance of intensively targeting systemic bottlenecks to HEI retention at facility level, a necessary complement to deploying rapidly scalable technologies and other higher-level initiatives.

Expanding access to non-communicable disease care in rural Malawi: outcomes from a retrospective cohort in an integrated NCD-HIV model

OBJECTIVES

Non-communicable diseases (NCDs) account for one-third of disability-adjusted life years in Malawi, and access to care is exceptionally limited. Integrated services with HIV are widely recommended, but few examples exist globally. We report descriptive outcomes from an Integrated Chronic Care Clinic (IC3).

DESIGN

This is a retrospective cohort study.

SETTING

The study includes an HIV-NCD clinic across 14 primary care facilities in the rural district of Neno, Malawi.

PARTICIPANTS

All new patients, including 6233 HIV-NCD diagnoses, enrolled between January 2015 and December 2017 were included. This included 3334 patients with HIV (59.7% women) and 2990 patients with NCD (67.3% women), 10% overall under age 15 years.

INTERVENTIONS

Patients were seen at their nearest health centre, with a hospital team visiting routinely to reinforce staffing. Data were collected on paper forms and entered into an electronic medical record.

PRIMARY AND SECONDARY OUTCOME MEASURES

Routine clinical measurements are reported at 1-year post-enrolment for patients with more than one visit. One-year retention is reported by diagnosis.

RESULTS

NCD diagnoses were 1693 hypertension, 668 asthma, 486 epilepsy, 149 diabetes and 109 severe mental illness. By December 2018, 8.3% of patients with NCD over 15 years were also on HIV treatment. One-year retention was 85% for HIV and 72% for NCDs, with default in 8.4% and 25.5% and deaths in 4.0% and 1.4%, respectively. Clinical outcomes showed statistically significant improvement for hypertension, diabetes, asthma and epilepsy. Of the 1807 (80%) of patients with HIV with viral load results, 85% had undetectable viral load.

CONCLUSIONS

The IC3 model, built on an HIV platform, facilitated rapid decentralisation and access to NCD services in rural Malawi. Clinical outcomes and retention in care are favourable, suggesting that integration of chronic disease care at the primary care level poses a way forward for the large dual burden of HIV and chronic NCDs.

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.

Integrating the prevention of mother-to-child transmission of HIV into primary healthcare services after AIDS denialism in South Africa: perspectives of experts and health care workers - a qualitative study

Background

Integrating Prevention of Mother-to-Child Transmission (PMTCT) programmes into routine health services under complex socio-political and health system conditions is a priority and a challenge. The successful rollout of PMTCT in sub-Saharan Africa has decreased Human Immunodeficiency Virus (HIV), reduced child mortality and improved maternal health. In South Africa, PMTCT is now integrated into existing primary health care (PHC) services and this experience could serve as a relevant example for integrating other programmes into comprehensive primary care. This study explored the perspectives of both experts or key informants and frontline health workers (FHCWs) in South Africa on PMTCT integration into PHC in the context of post-AIDS denialism using a Complex Adaptive Systems framework.

Methods

A total of 20 in-depth semi-structured interviews were conducted; 10 with experts including national and international health systems and HIV/PMTCT policy makers and researchers, and 10 FHCWs including clinic managers, nurses and midwives. All interviews were conducted in person, audio-recorded and transcribed. Three investigators collaborated in coding transcripts and used an iterative approach for thematic analysis.

Results

Experts and FHCWs agreed on the importance of integrated PMTCT services. Experts reported a slow and partial integration of PMTCT programmes into PHC following its initial rollout as a stand-alone programme in the aftermath of the AIDS denialism period. Experts and FHCWs diverged on the challenges associated with integration of PMTCT. Experts highlighted bureaucracy, HIV stigma and discrimination and a shortage of training for staff as major barriers to PMTCT integration. In comparison, FHCWs emphasized high workloads, staff turnover and infrastructural issues (e.g., lack of rooms, small spaces) as their main challenges to integration. Both experts and FHCWs suggested that working with community health workers, particularly in the post-partum period, helped to address cases of loss to follow-up of women and their babies and to improve linkages to polymerase-chain reaction (PCR) testing and immunisation.

Conclusions

Despite organised efforts in South Africa, experts and FHCWs reported multiple barriers for the full integration of PMTCT in PHC, especially postpartum. The results suggest opportunities to address operational challenges towards more integrated PMTCT and other health services in order to improve maternal and child health.

Landscape analysis of healthcare policy: the instrumental role of governance in HIV/AIDS services integration framework

Introduction

Low and middle-income countries HIV/AIDS interventions are yet to achieve the desired levels of health outcome due to lack of effectiveness and efficiency in programming, a challenge associated with resource limitations, fragmented services, complexities in population and disease characteristics including political landscape. The objective of this study was to establish the instrumental role of governance in the implementation of HIV/AIDS services integration policy framework, with focus on organization structure, participation in decision making, collaboration, stakeholder engagement, political commitment as study variables.

Methods

Using a mixed method design, a total number of 30 health workers, 5 county AIDS services coordinators (CASCOs), 8 sub-CASCOs and 3 representatives of inter coordinating committee were interviewed in compliance with ethical protocols. Multi-stage sampling techniques was used to select counties in Kenya, health institutions and respondents. Quantitative and qualitative data was generated by administering semi structured questionnaire and key informant interview guide.

Results

Generated from excel sheet and NVivo software indicate that organization structures existed and clarity and ease of work varied across the different levels of care. Collaboration efforts, however varied, created synergy in policy framework implementation and political commitment complemented the various leadership actions for successful implementation of integration policy framework.

Conclusion

Governance role is indispensable in the implementation of health policy framework. Policy makers need accurate epidemiological and demographic information to implement contextualized policy framework necessary for sustained improvement in health outcomes.

Treatment outcomes of adults with new onset pulmonary tuberculosis in Pretoria, South Africa

A persistently high burden of tuberculosis (TB) and low cure rates in South Africa call for frequent assessment of the effectiveness of the TB programme. We conducted a retrospective cohort study to evaluate treatment outcomes and associated factors among new TB patients taking standard regimen 1 TB treatment during 2010 in Pretoria, using the World Health Organization's six treatment outcomes classification. The 85 participants (of whom 59% were female) had co-infection with HIV in 70%. A total of 52% completed treatment, but only 15% were officially cured; 13% died and only 35% had an end-of-treatment sputum test. The treatment success rate (cured and complete treatment) was 67%. Completion of TB treatment was associated with HIV status (P = 0.02) and TB diagnosis using only sputum smear test (P = 0.02). Our results suggest non-compliance with standard TB guidelines by healthcare workers. We therefore advise future interventions should target both patients and healthcare workers.

NGOs, austerity, and universal health coverage in Mozambique

In many African countries, hundreds of health-related NGOs are fed by a chaotic tangle of donor funding streams. The case of Mozambique illustrates how this NGO model impedes Universal Health Coverage. In the 1990s, NGOs multiplied across post-war Mozambique: the country’s structural adjustment program constrained public and foreign aid expenditures on the public health system, while donors favored private contractors and NGOs. In the 2000s, funding for HIV/AIDS and other vertical aid from many donors increased dramatically. In 2004, the United States introduced PEPFAR in Mozambique at nearly 500 million USD per year, roughly equivalent to the entire budget of the Ministry of Health. To be sure, PEPFAR funding has helped thousands access antiretroviral treatment, but over 90% of resources flow “off-budget” to NGO “implementing partners,” with little left for the public health system. After a decade of this major donor funding to NGOs, public sector health system coverage had barely changed. In 2014, the workforce/ population ratio was still among the five worst in the world at 71/10000; the health facility/per capita ratio worsened since 2009 to only 1 per 16,795. Achieving UHC will require rejection of austerity constraints on public sector health systems, and rechanneling of aid to public systems building rather than to NGOs.

Integrated HIV-Care Into Primary Health Care Clinics and the Influence on Diabetes and Hypertension Care: An Interrupted Time Series Analysis in Free State, South Africa Over 4 Years

BACKGROUND

Noncommunicable diseases (NCDs), specifically diabetes and hypertension, are rising in high HIV-burdened countries such as South Africa. How integrated HIV care into primary health care (PHC) influences NCD care is unknown. We aimed to understand whether differences existed in NCD care (pre- versus post-integration) and how changes may relate to HIV patient numbers.

SETTING

Public sector PHC clinics in Free State, South Africa.

METHODS

Using a quasiexperimental design, we analyzed monthly administrative data on 4 indicators for diabetes and hypertension (clinic and population levels) during 4 years as HIV integration was implemented in PHC. Data represented 131 PHC clinics with a catchment population of 1.5 million. We used interrupted time series analysis at ±18 and ±30 months from HIV integration in each clinic to identify changes in trends postintegration compared with those in preintegration. We used linear mixed-effect models to study relationships between HIV and NCD indicators.

RESULTS

Patients receiving antiretroviral therapy in the 131 PHC clinics studied increased from 1614 (April 2009) to 57, 958 (April 2013). Trends in new diabetes patients on treatment remained unchanged. However, population-level new hypertensives on treatment decreased at ±30 months from integration by 6/100, 000 (SE = 3, P < 0.02) and was associated with the number of new patients with HIV on treatment at the clinics.

CONCLUSIONS

Our findings suggest that during the implementation of integrated HIV care into PHC clinics, care for hypertensive patients could be compromised. Further research is needed to understand determinants of NCD care in South Africa and other high HIV-burdened settings to ensure patient-centered PHC.

Is co-location of services with HIV care associated with improved HIV care outcomes? A systematic review

This systematic review identifies models of service co-location, a structural intervention strategy to remove barriers to HIV care and services, and examines their associations with HIV care outcomes. A cumulative database (e.g., MEDLINE, EMBASE) of HIV, AIDS, and STI literature was systematically searched and manual searches were conducted to identify relevant studies. Thirty-six studies were classified into six models of co-location: HIV care co-located with multiple ancillary services, tuberculosis (TB) care, non-HIV specific primary care, drug abuse treatment, prevention of mother to child transmission programs (PMTCT), and mental health care. More evidence of a positive association was seen for linkage to care and antiretroviral therapy (ART) uptake than for retention and viral suppression. Models of co-location that addressed HIV and non-HIV medical care issues (i.e., co-location with non-HIV specific primary care, PMTCT, and TB) had more positive associations, particularly for linkage to care and ART uptake, than other co-location models. While some findings are encouraging, more research with rigorous study designs is needed to strengthen the evaluation of, and evidence for, service co-location.

Health Provider Perspectives of Health Facility Preparedness and Organization in Implementation of Option B+ among Pregnant and Lactating Women in Central Uganda: A Qualitative Study

INTRODUCTION

Uganda adopted Option B+ for prevention of mother-to-child transmission (PMTCT) of HIV in 2012. However, there is limited data on preparedness and organization of Option B+ services. These data are critical in informing PMTCT programs and provision of universal antiretroviral therapy (ART) for all populations. This study explored health providers' experiences of preparedness and organization of Option B+ services in Central Uganda.

METHODS

Key informant interviews with 54 health providers from 6 health facilities in 3 districts were conducted. Thematic approach was employed to analyze data.

RESULTS

Themes identified on preparedness were training of frontline health providers and provision of Option B+ guidelines, supervision and mentorship, and provision of essential medicines and medical health supplies, whereas those concerning organization were HIV counseling and testing, ART initiation, follow-up, and patient support mechanisms. Innovations like use of expert clients, assessing women's readiness to start Option B+, and retaining women in antenatal care clinic depending on the need are important in provision of Option B+.

CONCLUSION

This study provides insights into preparedness and organization of Option B+ services which are important in provision of Option B+ and universal ART for all populations. Research around models of follow-up is recommended.

Evolution of Tuberculosis/Human Immunodeficiency Virus Services among Different Integrated Models in Myanmar: A Health Services Review

Myanmar is one of the highly affected countries by tuberculosis (TB) and human immunodeficiency virus (HIV) co-infection. We aimed to review the coverage of TB/HIV integrated services as well as to document the performance of this integrated services. A retrospective program review was conducted using the aggregated data of the National TB Programme (NTP) from 2005 to 2016. In Myanmar, TB/HIV services were initiated in seven townships in 2005. Townships were slowly expanded until 2013. After that, the momentum was increased by increasing the government budget allocation for NTP. In 2016, the whole country was eventually covered by TB/HIV services in different types of integration. Antiretroviral therapy (ART) coverage among HIV-positive TB patients remained low and it was the only significant difference among the three types of integration. Barriers of low ART coverage need to be investigated to reduce the burden of TB/HIV.

'Drug adherence levels are falling down again': health worker perceptions of women's service utilization before and after integration of HIV/AIDS services into general care in India

Integrated models of HIV/AIDS service delivery are believed to have advantages over stand-alone models of care from health planners' and providers' perspectives. Integration models differ, yet there is little information about the influence of differing models on workers' beliefs about models' efficacy. Here, we examine the effect of integration of HIV care into the general health system in India. In 2014, India replaced its stand-alone model of HIV service delivery-Community Care Centers (CCCs)-with a purported integrated model that delivers HIV medical services at general hospitals and HIV psychosocial services at nearby Care and Support Centers (CSCs). We examine 15 health workers' perceptions of how change from the earlier stand-alone model to the current model impacted women's care in a district in Uttar Pradesh, India. Results indicate that (1) Women's antiretroviral (ART) adherence and utilization of psychosocial support service for HIV/AIDS suffered when services were not provided at one site; (2) Provision of inpatient care in the CCC model offered women living in poverty personal safety in accessing HIV health services and promoted chances of competent ART usage and repeat service utilization; and (3) Although integration of HIV services with the general health system was perceived to improve patient anonymity and decrease chances of HIV-related stigma and discrimination, resource shortages continued to plague the integrated system while shifting costs of time and money to the patients. Findings suggest that integration efforts need to consider the context of service provision and the gendered nature of access to HIV care.

Small area estimation of under-5 mortality in Bangladesh, Cameroon, Chad, Mozambique, Uganda, and Zambia using spatially misaligned data

Background

The under-5 mortality rate (U5MR) is an important metric of child health and survival. Country-level estimates of U5MR are readily available, but efforts to estimate U5MR subnationally have been limited, in part, due to spatial misalignment of available data sources (e.g., use of different administrative levels, or as a result of historical boundary changes).

Methods

We analyzed all available complete and summary birth history data in surveys and censuses in six countries (Bangladesh, Cameroon, Chad, Mozambique, Uganda, and Zambia) at the finest geographic level available in each data source. We then developed small area estimation models capable of incorporating spatially misaligned data. These small area estimation models were applied to the birth history data in order to estimate trends in U5MR from 1980 to 2015 at the second administrative level in Cameroon, Chad, Mozambique, Uganda, and Zambia and at the third administrative level in Bangladesh.

Results

We found substantial variation in U5MR in all six countries: there was more than a two-fold difference in U5MR between the area with the highest rate and the area with the lowest rate in every country. All areas in all countries experienced declines in U5MR between 1980 and 2015, but the degree varied both within and between countries. In Cameroon, Chad, Mozambique, and Zambia we found areas with U5MRs in 2015 that were higher than in other parts of the same country in 1980. Comparing subnational U5MR to country-level targets for the Millennium Development Goals (MDG), we find that 12.8% of areas in Bangladesh did not meet the country-level target, although the country as whole did. A minority of areas in Chad, Mozambique, Uganda, and Zambia met the country-level MDG targets while these countries as a whole did not.

Conclusions

Subnational estimates of U5MR reveal significant within-country variation. These estimates could be used for identifying high-need areas and positive deviants, tracking trends in geographic inequalities, and evaluating progress towards international development targets such as the Sustainable Development Goals.

Strengthening the health workforce to support integration of HIV and noncommunicable disease services in sub-Saharan Africa

OBJECTIVE

The successful expansion of HIV services in sub-Saharan Africa has been a signature achievement of global public health. This article explores health workforce-related lessons from HIV scale-up, their implications for integrating noncommunicable disease (NCD) services into HIV programs, ways to ensure that healthcare workers have the knowledge, skills, resources, and enabling environment they need to provide comprehensive integrated HIV/NCD services, and discussion of a priority research agenda.

DESIGN AND METHODS

We conducted a scoping review of the published and 'gray' literature and drew upon our cumulative experience designing, implementing and evaluating HIV and NCD programs in low-resource settings.

RESULTS AND CONCLUSION

Lessons learned from HIV programs include the role of task shifting and the optimal use of multidisciplinary teams. A responsible and adaptable policy environment is also imperative; norms and regulations must keep pace with the growing evidence base for task sharing, and early engagement of regulatory authorities will be needed for successful HIV/NCD integration. Ex-ante consideration of work culture will also be vital, given its impact on the quality of service delivery. Finally, capacity building of a robust interdisciplinary workforce is essential to foster integrated patient-centered care. To succeed, close collaboration between the health and higher education sectors is needed and comprehensive competency-based capacity building plans for various health worker cadres along the education and training continuum are required. We also outline research priorities for HIV/NCD integration in three key domains: governance and policy; education, training, and management; and service delivery.

Strengthening primary eye care in South Africa: An assessment of services and prospective evaluation of a health systems support package

Visual impairment is a significant public health concern, particularly in low- and middle-income countries where eye care is predominantly provided at the primary healthcare (PHC) level, known as primary eye care. This study aimed to perform an evaluation of primary eye care services in three districts of South Africa and to assess whether an ophthalmic health system strengthening (HSS) package could improve these services. Baseline surveys were conducted in Cape Winelands District, Johannesburg Health District and Mopani District at 14, 25 and 36 PHC facilities, respectively. Thereafter, the HSS package, comprising group training, individual mentoring, stakeholder engagement and resource provision, was implemented in 20 intervention sites in Mopani District, with the remaining 16 Mopani facilities serving as control sites. At baseline, less than half the facilities in Johannesburg and Mopani had dedicated eye care personnel or sufficient space to measure visual acuity. Although visual acuity charts were available in most facilities, <50% assessed patients at the correct distance. Median score for availability of nine essential drugs was <70%. Referral criteria knowledge was highest in Cape Winelands and Johannesburg, with poor clinical knowledge across all districts. Several HSS interventions produced successful outcomes: compared to control sites there was a significant increase in the proportion of intervention sites with eye care personnel and resources such as visual acuity charts (p = 0.02 and <0.01, respectively). However, engaging with district pharmacists did not improve availability of essential drugs (p = 0.47). Referral criteria knowledge improved significantly in intervention sites (p<0.01) but there was no improvement in clinical knowledge (p = 0.76). Primary eye care in South Africa faces multiple challenges with regard to organisation of care, resource availability and clinical competence. The HSS package successfully improved some aspects of this care, but further development is warranted together with debate regarding the positioning of eye services at PHC level.

Sustainability of ARV provision in developing countries: challenging a framework based on program history

The provision of ARVs is central to HIV/AIDS programs, because of its impact on the course of the disease and on quality of life. Although first-line treatments costs have declined, treatment-associated expenses are steeper each year. Sustainability is therefore an important variable for the success of treatment programs. A conceptual framework on sustainability of ARV provision was developed, followed by data collection instruments. The pilot study was undertaken in Brazil. Bolivia, Peru and Mozambique, were visited. Key informants were identified and interviewed. Investigation of sustainability related to ARV provision involved implementation and routinization events of provision schemes. Evidence of greater sustainability potential was observed in Peru, where provision is implemented and routinized by the National HIV/AIDS program and expenditures met by the government. In Mozambique, provision is dependent on donations and external aid, but the country displays a great effort to incorporate ARV provision and care in routine healthcare activities. Bolivia, in addition to external dependence on financing and management of drug supply, presents problems regarding implementation and routinization. The conceptual framework was useful in recognizing events that influence sustainable ARV provision in these countries.

Causes of death among women aged 17-49 years between 2007 and 2010 in Maputo, Mozambique

Objectives

To describe causes of death among young women and estimate the role of HIV/AIDS as a cause in Maputo City, based on the civil death register.

Methods

Death data of 17–49 year–old women were abstracted from January 2007–March 2010 from the civil death register in Maputo City, registering overall about 15 000 deaths per–year. Causes of death in the register were either based on physicians’ diagnoses on death certificates or determined by asking questions to deceased relatives. Causes of death were written in Portuguese; we translated them into English and classified them into 106 codes using ICD–9; these codes were then categorized into 10 groups. Estimated populations from the 2007 census were used to calculate annual mortality rates. An earlier study was used to compare deaths in 2001.

Findings

A total of 9640 deaths (6510 for residents of Maputo City) were registered and 77% had a specified cause of death reported. HIV–deaths represented 36% of all deaths and 40% among 25–39 year–olds. The death rate did not increase linearly by age, as there was a peak among women aged 30–34 years. The overall annual death rate was 6.7 deaths per 1000 population, with a notable decline by year. Death rates for HIV slightly declined by year. HIV–deaths explained most of the peak in death rate among 30–34–year–olds. The share of HIV–deaths among all deaths increased from 18% in 2001 to 35% in 2007–2010. Sixty–eight percent of all and 92% of HIV–related deaths occurred in hospital, with no increase over time.

Conclusions

Routine death register was useful to study death rates, distribution of deaths, and change over time in the urban setting of Maputo during late 2000s. Over time, the death rate among 17–49 years old women seemed to have declined, but the relative contribution of HIV increased.

Health systems flattening - the failed promises of decentralisation in Mozambique

Over the past decade, health systems strengthening (HSS) has become a global health imperative. As an answer to the influence of large-scale initiatives and NGOs, HSS represents a backlash against disease-specific projects and funding. Depicted as a positive evolution, HSS advertises local autonomy, and a turn away from donor-driven agendas. Central to this shift was the hope that 'vertical' funding, especially for HIV/AIDS, could be better used to build up the 'crumbling core' of health infrastructure in sub-Saharan Africa. As part of the change in Mozambique, HIV specialty clinics known as 'day hospitals' were decentralised (closed down) nationwide. Done in the name of efficiency and increased treatment coverage, the full impacts of this remain uncharted. In this article, I critique the ethical adequacy of HSS as a reorganising principle, pointing out the pursuit not of robust health systems, but of easily monitored ones instead. Occurring alongside performance-based financing, HSS invites the removal of specialty services, exposing health systems to additional shaping by outside forces. Based on ethnography with HIV support groups, I suggest HSS was an inevitable policy choice, but partially coercive. Such changes are neither counter-hegemonic nor capable of ameliorating foreign distortions in the developing world.

Integration of antenatal care services with health programmes in low- and middle-income countries: systematic review

Background

Antenatal care (ANC) presents a potentially valuable platform for integrated delivery of additional health services for pregnant women–services that are vital to reduce the persistently high rates of maternal and neonatal mortality in low– and middle–income countries (LMICs). However, there is limited evidence on the impact of integrating health services with ANC to guide policy. This review assesses the impact of integration of postnatal and other health services with ANC on health services uptake and utilisation, health outcomes and user experience of care in LMICs.

Methods

Cochrane Library, MEDLINE, Embase, CINAHL Plus, POPLINE and Global Health were searched for studies that compared integrated models for delivery of postnatal and other health services with ANC to non–integrated models. Risk of bias of included studies was assessed using the Cochrane Effective Practice and Organisation of Care (EPOC) criteria and the Newcastle–Ottawa Scale, depending on the study design. Due to high heterogeneity no meta–analysis could be conducted. Results are presented narratively.

Findings

12 studies were included in the review. Limited evidence, with moderate– to high–risk of bias, suggests that integrated service delivery results in improved uptake of essential health services for women, earlier initiation of treatment, and better health outcomes. Women also reported improved satisfaction with integrated services.

Conclusions

The reported evidence is largely based on non–randomised studies with poor generalizability, and therefore offers very limited policy guidance. More rigorously conducted and geographically diverse studies are needed to better ascertain and quantify the health and economic benefits of integrating health services with ANC.

Does service integration improve technical quality of care in low-resource settings? An evaluation of a model integrating HIV care into family planning services in Kenya

The aim of this study was to investigate association between HIV and family planning integration and technical quality of care. The study focused on technical quality of client-provider consultation sessions. The cross-sectional study observed 366 client-provider consultation sessions and interviewed 37 health care providers in 12 public health facilities in Kenya. Multilevel random intercept and linear regression models were fitted to the matched data to investigate relationships between service integration and technical quality of care as well as associations between facility-level structural and provider factors and technical quality of care. A sensitivity analysis was performed to test for hidden bias. After adjusting for facility-level structural factors, HIV/family planning integration was found to have significant positive effect on technical quality of the consultation session, with average treatment effect 0.44 (95% CI: 0.63-0.82). Three of the 12 structural factors were significantly positively associated with technical quality of consultation session including: availability of family planning commodities (9.64; 95% CI: 5.07-14.21), adequate infrastructure (5.29; 95% CI: 2.89-7.69) and reagents (1.48; 95% CI: 1.02-1.93). Three of the nine provider factors were significantly positively associated with technical quality of consultation session: appropriate provider clinical knowledge (3.14; 95% CI: 1.92-4.36), job satisfaction (2.02; 95% CI: 1.21-2.83) and supervision (1.01; 95% CI: 0.35-1.68), while workload (-0.88; 95% CI: -1.75 to - 0.01) was negatively associated. Technical quality of the client-provider consultation session was also determined by duration of the consultation and type of clinic visit and appeared to depend on whether the clinic visit occurred early or later in the week. Integration of HIV care into family planning services can improve the technical quality of client-provider consultation sessions as measured by both health facility structural and provider factors.

Harmonization of community health worker programs for HIV: A four-country qualitative study in Southern Africa

BACKGROUND

Community health worker (CHW) programs are believed to be poorly coordinated, poorly integrated into national health systems, and lacking long-term support. Duplication of services, fragmentation, and resource limitations may have impeded the potential impact of CHWs for achieving HIV goals. This study assesses mediators of a more harmonized approach to implementing large-scale CHW programs for HIV in the context of complex health systems and multiple donors.

METHODS AND FINDINGS

We undertook four country case studies in Lesotho, Mozambique, South Africa, and Swaziland between August 2015 and May 2016. We conducted 60 semistructured interviews with donors, government officials, and expert observers involved in CHW programs delivering HIV services. Interviews were triangulated with published literature, country reports, national health plans, and policies. Data were analyzed based on 3 priority areas of harmonization (coordination, integration, and sustainability) and 5 components of a conceptual framework (the health issue, intervention, stakeholders, health system, and context) to assess facilitators and barriers to harmonization of CHW programs. CHWs supporting HIV programs were found to be highly fragmented and poorly integrated into national health systems. Stakeholders generally supported increasing harmonization, although they recognized several challenges and disadvantages to harmonization. Key facilitators to harmonization included (i) a large existing national CHW program and recognition of nongovernmental CHW programs, (ii) use of common incentives and training processes for CHWs, (iii) existence of an organizational structure dedicated to community health initiatives, and (iv) involvement of community leaders in decision-making. Key barriers included a wide range of stakeholders and lack of ownership and accountability of non-governmental CHW programs. Limitations of our study include subjectively selected case studies, our focus on decision-makers, and limited generalizability beyond the countries analyzed.

CONCLUSION

CHW programs for HIV in Southern Africa are fragmented, poorly integrated, and lack long-term support. We provide 5 policy recommendations to harmonize CHW programs in order to strengthen and sustain the role of CHWs in HIV service delivery.

Integrating PMTCT Into Maternal, Newborn, and Child Health and Related Services: Experiences From the Global Plan Priority Countries

The urgency to scale-up sustainable programs for the prevention of mother-to-child transmission of HIV (PMTCT) prompted priority countries of the Global Plan Toward the Elimination of New HIV Infections Among Children by 2015 and Keeping Their Mothers Alive (Global Plan) to expand the delivery of PMTCT services through greater integration with sexual and reproductive health and child health services. Countries approached integration-what, where, and how services are provided-in diverse ways, with predominantly favorable results. Approaches to integrated services have increased access to a broader range of PMTCT interventions, and they also have proved to be largely acceptable to clients and providers. The integration of PMTCT interventions with maternal, newborn, and child health settings was supported by strategies to reconfigure service delivery to provide additional services, including shifting tasks to nurses (such as initiating antiretroviral therapy and providing long-term follow-up). This was complemented by supporting community outreach and integrating HIV and sexual and reproductive health services bidirectionally, including by providing family planning through antiretroviral therapy clinics and HIV testing in family planning clinics. A systematic and rigorous study of country experiences integrating HIV and maternal, newborn, and child health services, including maternal and pediatric TB services, cost analysis, could provide valuable lessons and demonstrate how such integration can improve systems for health care delivery.

The continuum of HIV care in South Africa: implications for achieving the second and third UNAIDS 90-90-90 targets

BACKGROUND

We characterize engagement with HIV care in South Africa in 2012 to identify areas for improvement towards achieving global 90-90-90 targets.

METHODS

Over 3.9 million CD4 cell count and 2.7 million viral load measurements reported in 2012 in the public sector were extracted from the national laboratory electronic database. The number of persons living with HIV (PLHIV), number and proportion in HIV care, on antiretroviral therapy (ART) and with viral suppression (viral load <400 copies/ml) were estimated and stratified by sex and age group. Modified Poisson regression approach was used to examine associations between sex, age group and viral suppression among persons on ART.

RESULTS

We estimate that among 6511 000 PLHIV in South Africa in 2012, 3300 000 individuals (50.7%) accessed care and 32.9% received ART. Although viral suppression was 73.7% among the treated population in 2012, the overall percentage of persons with viral suppression among all PLHIV was 23.8%. Linkage to HIV care was lower among men (38.5%) than among women (57.2%). Overall, 47.1% of those aged 0-14 years and 47.0% of those aged 15-49 years were linked to care compared with 56.2% among those aged above 50 years.

CONCLUSION

Around a quarter of all PLHIV have achieved viral suppression in South Africa. Men and younger persons have poorer linkage to HIV care. Expanding HIV testing, strengthening prompt linkage to care and further expansion of ART are needed for South Africa to reach the 90-90-90 target. Focus on these areas will reduce the transmission of new HIV infections and mortality in the general population.

Political economy of decentralising HIV and AIDS treatment services to primary healthcare facilities in three Nigerian states

Decentralisation is defined as the dispersion, distribution or transfer of resources, functions and decision-making power from a central authority to regional and local authorities. It is usually accompanied by assignment of accountability and responsibility for results. Fundamental to understanding decentralisation is learning what motivates central governments to give up power and resources to local governments, and the practical significance of this on their positions regarding decentralisation. This study examined key political and institutional influences on role-players' capacity to support decentralisation of HIV and AIDS treatment services to primary healthcare facilities, and implications for sustainability. In-depth interviews were conducted with 55 purposively selected key informants, drawn from three Nigerian states that were at different stages of decentralising HIV and AIDS treatment services to primary care facilities. Key informants represented different categories of role-players involved in HIV and AIDS control programmes. Thematic framework analysis of data was done. Support for decentralisation of HIV and AIDS treatment services to primary healthcare facilities was substantial among different categories of actors. Political factors such as the local and global agenda for health, political tenure and party affiliations, and institutional factors such as consolidation of decision-making power and improvements in career trajectories, influenced role-players support for decentralisation of HIV and AIDS treatment services. It is feasible and acceptable to decentralise HIV and AIDS treatment services to primary healthcare facilities, to help improve coverage. However, role-players' support largely depends on how well the reform aligns with political structures and current institutional practices.

Dedicated health systems strengthening of the Global Fund to Fight AIDS, Tuberculosis, and Malaria: an analysis of grants

BACKGROUND

This study aims to understand the determinants of the Global Fund to Fight AIDS, Tuberculosis, and Malaria's dedicated channel for health systems strengthening (HSS) funding across countries and to analyze their health system priorities expressed in budgets and performance indicators.

METHODS

We obtained publicly available data for disease-specific and HSS grants from the Global Fund over 2004-2013 prior to the new funding model. Regression analysis was employed to assess the determinants of dedicated HSS funding across 111 countries. Documents for 27 dedicated HSS grants including budgets and performance indicators were collected, and activities were analyzed by health system functions.

RESULTS

HSS funding per capita is significantly associated with TB and HIV funding per capita, but not per capita income and health worker density. Of 27 dedicated HSS grants, 11 had line-item budgets publicly available, in which health workforce and medical products form the majority (89% or US$132 million of US$148 million) of funds. Yet these areas accounted for 41.7% (215) of total 516 performance indicators.

CONCLUSIONS

Health worker densities were not correlated with HSS funding, despite the emphasis on health workforce in budgets and performance indicators. Priorities in health systems in line-item budgets differ from the numbers of indicators used.

Achieving development goals for HIV, tuberculosis and malaria in sub-Saharan Africa through integrated antenatal care: barriers and challenges

BACKGROUND

The global health community is currently transitioning from the Millennium Development Goals (MDGs) to the Sustainable Development Goals (SDGs). Unfortunately, progress towards maternal, newborn and infant health MDGs has lagged significantly behind other key health goals, demanding a renewed global effort in this key health area. The World Health Organization and other institutions heralded integrated antenatal care (ANC) as the best way to address the inter-related health issues of HIV, tuberculosis (TB) and malaria in the high risk groups of pregnant women and infants; integrated ANC services also offer a mechanism to address slow progress towards improved maternal health.

DISCUSSION

There is remarkably limited evidence on best practice approaches of program implementation, acceptability and effectiveness for integrated ANC models targeting multiple diseases. Here, we discuss current integrated ANC global guidelines and the limited literature describing integrated ANC implementation and evidence for their role in addressing HIV, malaria and TB during pregnancy in sub-Saharan Africa. We highlight the paucity of data on the effectiveness of integrated ANC models and identify significant structural barriers in the health system (funding, infrastructure, distribution, human resources), the adoption system (limited buy-in from implementers, leadership, governance) and, in the broader context, patient-centred barriers (fear, stigma, personal burdens) and barriers in funding structures. We highlight recommendations for action and discuss avenues for the global health community to develop systems to integrate multiple disease programs into ANC models of care that better address these three priority infectious diseases. With the current transition to the SDGs and concerns regarding the failure to meet maternal health MDGs, the global health community, researchers, implementers and funding bodies must work together to ensure the establishment of quality operational and implementation research to inform integrated ANC models. It is imperative that the global health community engages in a timely discussion about such implementation innovations and instigates appropriate actions to ensure advances in maternal health are sufficient to meet applicable SDGs.

Performance-based incentives may be appropriate to address challenges to delivery of prevention of vertical transmission of HIV services in rural Mozambique: a qualitative investigation

BACKGROUND

Performance-based incentives (PBIs) have garnered global attention as a promising strategy to improve healthcare delivery to vulnerable populations. However, literature gaps in the context in which an intervention is implemented and how the PBIs were developed exist. Therefore, we (1) characterized the barriers and promoters to prevention of vertical transmission of HIV (PVT) service delivery in rural Mozambique, where the vertical transmission rate is 12 %, and (2) assessed the appropriateness for a PBI's intervention and application to PVT.

METHODS

We conducted 24 semi-structured interviews with nurses, volunteers, community health workers, and traditional birth attendants about the barriers and promoters they experienced delivering PVT services. We then explored emergent themes in subsequent focus group discussions (n = 7, total participants N = 92) and elicited participant perspectives on PBIs. The ecological motivation-opportunity-ability framework guided our iterative data collection and thematic analysis processes.

RESULTS

The interviews revealed that while all health worker cadres were motivated intrinsically and by social recognition, they were dissatisfied with low and late remuneration. Facility-based staff were challenged by factors across the rest of the ecological levels, primarily in the opportunity domain, including the following: poor referral and record systems (work mandate), high workload, stock-outs, poor infrastructure (facility environment), and delays in obtaining patient results and donor payment discrepancies (administrative). Community-based cadres' opportunity challenges included lack of supplies, distance (work environment), lack of incorporation into the health system (administration), and ability challenges of incorrect knowledge (health worker). PBIs based on social recognition and that enable action on intrinsic motivation through training, supervision, and collaboration were thought to have the most potential for targeting improvements in record and referral systems and better integrating community-based health workers into the health system. Concerns about the implementation of incentives included neglect of non-incentivized tasks and distorted motivation among colleagues.

CONCLUSIONS

We found that highly motivated health workers encountered severe opportunity challenges in their PVT mandate. PBIs have the potential to address key barriers that facility- and community-based health workers encounter when delivering PVT services, specifically by building upon existing intrinsic motivation and leveraging highly valued social recognition. We recommend a controlled intervention to monitor incentives' effects on worker motivation and non-incentivized tasks to generate insights about the feasibility of PBIs to improve the delivery of PVT services.

Interventions to improve the rate or timing of initiation of antiretroviral therapy for HIV in sub-Saharan Africa: meta-analyses of effectiveness

INTRODUCTION

As global policy evolves toward initiating lifelong antiretroviral therapy (ART) regardless of CD4 count, initiating individuals newly diagnosed with HIV on ART as efficiently as possible will become increasingly important. To inform progress, we conducted a systematic review of pre-ART interventions aiming to increase ART initiation in sub-Saharan Africa.

METHODS

We searched PubMed, Embase and the ISI Web of Knowledge from 1 January 2008 to 1 March 2015, extended in PubMed to 25 May 2016, for English language publications pertaining to any country in sub-Saharan Africa and reporting on general adult populations. We included studies describing interventions aimed at increasing linkage to HIV care, retention in pre-ART or uptake of ART, which reported ART initiation as an outcome. We synthesized the evidence on causal intervention effects in meta-analysis of studies belonging to distinct intervention categories.

RESULTS AND DISCUSSION

We identified 22 studies, which evaluated 25 interventions and included data on 45,393 individual patients. Twelve of twenty-two studies were observational. Rapid/point-of-care (POC) CD4 count technology (seven interventions) (relative risk, RR: 1.26; 95% confidence interval, CI: 1.02-1.55), interventions within home-based testing (two interventions) (RR: 2.00; 95% CI: 1.36-2.92), improved clinic operations (three interventions) (RR: 1.36; 95% CI: 1.25-1.48) and a package of patient-directed services (three interventions) (RR: 1.54; 95% CI: 1.20-1.97) were all associated with increased ART initiation as was HIV/TB service integration (three interventions) (RR: 2.05; 95% CI: 0.59-7.09) but with high imprecision. Provider-initiated testing (three interventions) was associated with reduced ART initiation (RR: 0.91; 95% CI: 0.86-0.97). Counselling and support interventions (two interventions) (RR 1.08; 95% CI: 0.94-1.26) had no impact on ART initiation. Overall, the evidence was graded as low or moderate quality using the GRADE criteria.

CONCLUSIONS

The literature on interventions to increase uptake of ART is limited and of mixed quality. POC CD4 count and improving clinic operations show promise. More implementation research and evaluation is needed to identify how best to offer treatment initiation in a manner that is both efficient for service providers and effective for patients without jeopardizing treatment outcomes.

From decentralization to commonization of HIV healthcare resources: keys to reduction in health disparity and equitable distribution of health services in Nigeria

Access to quality care is essential for improved health outcomes. Decentralization improves access to healthcare services at lower levels of care, but it does not dismantle structural, funding and programming restrictions to access, resulting in inequity and inequality in population health. Unlike decentralization, Commonization Model of care reduces health inequalities and inequity, dismantles structural, funding and other program related obstacles to population health. Excellence and Friends Management Care Center (EFMC) using Commonization Model (CM), fully integrated HIV services into core health services in 121 supported facilities. This initiative improved access to care, treatment, support services, reduced stigmatization/discrimination, and improved uptake of HTC. We call on governments to adequately finance CM for health systems restructuring towards better health outcomes.

Assessment of linkages from HIV testing to enrolment and retention in HIV care in Central Mozambique

Introduction

Effectiveness of the rapid expansion of antiretroviral therapy (ART) throughout sub-Saharan Africa is highly dependent on adequate enrolment and retention in HIV care. However, the measurement of both has been challenging in these settings. This study aimed to assess enrolment and retention in HIV care (pre-ART and ART) among HIV-positive adults in Central Mozambique, including identification of barriers and facilitators.

Methods

We assessed linkages to and retention in HIV care using a mixed quantitative and qualitative approach in six districts of Manica and Sofala provinces. We analyzed routine district and health facility monthly reports and HIV care registries from April 2012 to March 2013 and used single imputation and trimmed means to adjust for missing values. In eight health facilities in the same districts and period, we assessed retention in HIV care among 795 randomly selected adult patient charts (15 years and older). We also conducted 25 focus group discussions and 53 in-depth interviews with HIV-positive adults, healthcare providers and community members to identify facilitators and barriers to enrolment and retention in HIV care.

Results

Overall, 46% of the monthly HIV testing reports expected at the district level were missing, compared to 6.4% of the pre-ART registry reports. After adjustment for missing values, we estimated that the aggregate numbers of adults registered in pre-ART was 75% of the number of persons tested HIV-positive in the six districts. In the eight health facilities, 40% of the patient charts for adults enrolled in pre-ART and 44% in ART were missing. Of those on ART for whom charts were found, retention in treatment within 90 and 60 days prior to the study team visit was 34 and 25%, respectively. Combining these multiple data sources, the overall estimated retention was 18% in our sample. Individual-level factors were perceived to be key influences to enrolment in HIV care, while health facility and structural-level factors were perceived to be key influences of retention.

Conclusions

Efforts to increase linkages to and retention in HIV care should address individual, health facility, and structural-level factors in Central Mozambique. However, their outcomes cannot be reliably assessed without improving the quality of routine health information systems.

Barriers and enablers to integrating maternal and child health services to antenatal care in low and middle income countries

Antenatal care (ANC) represents a delivery platform for a broad range of health services; however, these opportunities are insufficiently utilised. This review explores key barriers and enablers for successful integration of health s"ervices with ANC in different contexts. Data from peer‐reviewed and grey literature were organised using the SURE checklist. We identified 46 reports focusing on integration of HIV, tuberculosis, malaria, syphilis or nutrition services with ANC from Asia, Africa and the Pacific. Perspectives of service users and providers, social and political factors, and health system characteristics (such as resource availability and organisational structures) affected ease of integration.

Tweetable abstract

Health system factors, context and stakeholders must be considered for integrated antenatal care services.

Implementing Implementation Science: An Approach for HIV Prevention, Care and Treatment Programs

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