Noncommunicable Disease (NCD) strategic plans in low- and lower-middle income Sub-Saharan Africa: framing and policy response

Pharmacokinetic-Guided Hydroxyurea to Reduce Transfusions in Ugandan Children with Sickle Cell Anemia: Study Design of the Alternative Dosing And Prevention of Transfusions Trial

INTRODUCTION

People with sickle cell anemia (SCA) may require frequent blood transfusions to treat acute and chronic complications. Hydroxyurea is a life-saving treatment for SCA that could also decrease the need for blood transfusions. Inadequate medication access and challenges in dose optimization limit the widespread use of hydroxyurea in Africa. If feasible, pharmacokinetic (PK) dosing might improve dose determination to minimize toxicities and maximize clinical benefits. The Alternative Dosing And Prevention of Transfusions (ADAPT, NCT05662098) trial will analyze the impact of hydroxyurea on transfusion rate and serve as a pilot study to evaluate the feasibility of PK-guided hydroxyurea dosing in Uganda.

METHODS

Herein we describe the rationale and design of ADAPT, a prospective cohort study of ∼100 children with SCA in Jinja, Uganda. The primary hypothesis is that hydroxyurea will decrease blood transfusion use by ≥ 50%, comparing the transfusion incidence rate ratio between a 3-month pretreatment and a 12-month treatment period. A key secondary hypothesis is that our PK-dosing approach will generate a suitable hydroxyurea dose for ≥80% of participants. Every ADAPT participant will undergo hydroxyurea PK testing, and if a dose is generated within 15-35 mg/kg/day, participants will start on their individualized dose. If not, they will start on a default dose of 20 mg/kg/day. Hydroxyurea dose optimization will occur with periodic dose adjustments.

CONCLUSION

Overall, demonstrating the reduction in blood transfusion utilization with hydroxyurea treatment would provide leverage to increase hydroxyurea access, and PK-guided hydroxyurea dosing should optimize the safe and effective treatment of SCA across sub-Saharan Africa.

Health seeking behaviours and private sector delivery of care for non-communicable diseases in low- and middle-income countries: a systematic review

BACKGROUND

Globally, non-communicable diseases (NCDs) are the leading cause of mortality and morbidity placing a huge burden on individuals, families and health systems, especially in low- and middle-income countries (LMICs). This rising disease burden calls for policy responses that engage the entire health care system. This study aims to synthesize evidence on how people with NCDs choose their healthcare providers in LMICs, and the outcomes of these choices, with a focus on private sector delivery.

METHODS

A systematic search for literature following PRISMA guidelines was conducted. We extracted and synthesised data on the determinants and outcomes of private health care utilisation for NCDs in LMICs. A quality and risk of bias assessment was performed using the Mixed Methods Appraisal Tool (MMAT).

RESULTS

We identified 115 studies for inclusion. Findings on determinants and outcomes were heterogenous, often based on a particular country context, disease, and provider. The most reported determinants of seeking private NCD care were patients having a higher socioeconomic status; greater availability of services, staff and medicines; convenience including proximity and opening hours; shorter waiting times and perceived quality. Transitioning between public and private facilities is common. Costs to patients were usually far higher in the private sector for both inpatient and outpatient settings. The quality of NCD care seems mixed depending on the disease, facility size and location, as well as the aspect of quality assessed.

CONCLUSION

Given the limited, mixed and context specific evidence currently available, adapting health service delivery models to respond to NCDs remains a challenge in LMICs. More robust research on health seeking behaviours and outcomes, especially through large multi-country surveys, is needed to inform the effective design of mixed health care systems that effectively engage both public and private providers.

Health seeking behaviours and private sector delivery of care for non-communicable diseases in low- and middle-income countries: protocol for a systematic review

INTRODUCTION

The burden of non-communicable diseases (NCDs) has increased substantially in low- and middle-income countries (LMICs), and adapting health service delivery models to address this remains a challenge. Many patients with NCD seek private care at different points in their encounters with the health system, but the determinants and outcomes of these choices are insufficiently understood. The proposed systematic review will help inform the governance of mixed health systems towards achieving the goal of universal health coverage. This protocol details our intended methodological and analytical approaches, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).

METHODS AND ANALYSIS

Following the PRISMA approach, this systematic review will develop a descriptive synthesis of the determinants and outcomes of private healthcare utilisation for NCDs in LMICs. The databases Embase, Medline, Web of Science Core Collection, EconLit, Global Index Medicus and Google Scholar will be searched for relevant studies published in English between period 1 January 2010 and 30 June 2022 with additional searching of reference lists. The study selection process will involve a title-abstract and full-text review, guided by clearly defined inclusion and exclusion criteria. A quality and risk of bias assessment will be done for each study using the Mixed Methods Appraisal Tool.

ETHICS AND DISSEMINATION

Ethical approval is not required because this review is based on data collected from publicly available materials. The results will be published in a peer-reviewed journal and presented at related scientific events.

Decision makers perceptions and experiences of developing population-level interventions targeting risk factors for hypertension and diabetes in South Africa: a qualitative study

BACKGROUND

People in low- and middle-income countries are disproportionately affected by Noncommunicable diseases (NCDs). NCD's such as heart disease, cancer, chronic respiratory disease, and diabetes, are the leading cause of premature death worldwide and represent an emerging global health threat. The purpose of this qualitative study was to explore decision makers perceptions of developing population-level interventions (policies and programmes), targeting risk factors for hypertension and diabetes, in South Africa.

METHODS

Using purposive sampling we recruited fifteen participants, who were well informed about the policies, programs or supportive environment for prevention and management of diabetes and hypertension in South Africa. We conducted 12 individual interviews and 1 group interview (consisting of 3 participants). Data was analysed thematically in NVivo. The results were shared and discussed in two consultative stakeholder workshops, with participants, as part of a member validation process in qualitative research. All communication with participants was done virtually using MS Teams or ZOOM.

RESULTS

For development of population-level interventions, key enablers included, stakeholders' engagement and collaboration, contextualization of policies and programs, and evaluation and organic growth. Challenges for supportive policy and program formulation, and to enable supportive environments, included the lack of time and resources, lack of consultation with stakeholders, regulations and competing priorities, and ineffective monitoring and evaluation. The main drivers of population-level interventions for diabetes and hypertension were perceived as the current contextual realities, costs, organizational reasons, and communication between various stakeholders.

CONCLUSION

To address the risk factors for hypertension and diabetes in South Africa, policies and programs must account for the needs of the public and the historical and socio-economic climate. Feasibility and sustainability of programs can only be ensured when the resources are provided, and environments enabled to promote behavior change on a population-level. A holistic public health approach, which is contextually relevant, and evidence informed, is considered best practice in the formulation of population-level interventions.

Ghana's Adherence to PASCAR's 10-Point Action Plan towards Hypertension Control: A Scoping Review

The continuous increase in the prevalence of hypertension in Ghana has led to various interventions aimed at controlling the disease burden. Nonetheless, these interventions have yielded poor health outcomes. Subsequently, the Pan-African Society of Cardiology (PASCAR), established a 10-point action plan for inclusion in policies to aid control of hypertension. This scoping review assessed the adherence of health policies to the 10-point action plan towards hypertension control/reduction in Ghana. Eight health policies met the inclusion criteria and were assessed. The programme evaluation and policy design framework were used for synthesis and analysis of extracted data. Overall, there was poor adherence to hypertension control observed in the policies. Specifically, there were low levels of integrating hypertension control/reduction measures, a poor task-sharing approach, and poor financial resource allocations to tackle hypertension control/reduction in most of the policies. There was also low support for research to produce evidence to guide future interventions. For Ghana to achieve the global target of reducing hypertension by the year 2025, its health policies must adhere to evidence-based interventions in hypertension management/control. The study recommends a follow-up study among hypertension patients and healthcare professionals to evaluate the factors militating against hypertension management/control in Ghana.

Cancer in sub-Saharan Africa: a Lancet Oncology Commission

In sub-Saharan Africa (SSA), urgent action is needed to curb a growing crisis in cancer incidence and mortality. Without rapid interventions, data estimates show a major increase in cancer mortality from 520 348 in 2020 to about 1 million deaths per year by 2030. Here, we detail the state of cancer in SSA, recommend key actions on the basis of analysis, and highlight case studies and successful models that can be emulated, adapted, or improved across the region to reduce the growing cancer crises. Recommended actions begin with the need to develop or update national cancer control plans in each country. Plans must include childhood cancer plans, managing comorbidities such as HIV and malnutrition, a reliable and predictable supply of medication, and the provision of psychosocial, supportive, and palliative care. Plans should also engage traditional, complementary, and alternative medical practices employed by more than 80% of SSA populations and pathways to reduce missed diagnoses and late referrals. More substantial investment is needed in developing cancer registries and cancer diagnostics for core cancer tests. We show that investments in, and increased adoption of, some approaches used during the COVID-19 pandemic, such as hypofractionated radiotherapy and telehealth, can substantially increase access to cancer care in Africa, accelerate cancer prevention and control efforts, increase survival, and save billions of US dollars over the next decade. The involvement of African First Ladies in cancer prevention efforts represents one practical approach that should be amplified across SSA. Moreover, investments in workforce training are crucial to prevent millions of avoidable deaths by 2030. We present a framework that can be used to strategically plan cancer research enhancement in SSA, with investments in research that can produce a return on investment and help drive policy and effective collaborations. Expansion of universal health coverage to incorporate cancer into essential benefits packages is also vital. Implementation of the recommended actions in this Commission will be crucial for reducing the growing cancer crises in SSA and achieving political commitments to the UN Sustainable Development Goals to reduce premature mortality from non-communicable diseases by a third by 2030.

Challenges and enablers for implementation of WHO 'Best buys' interventions targeting risk factors of diabetes and hypertension in South Africa: a mixed methods study

Introduction

World Health Organization (WHO) recommends the implementation of 'Best buys', cost-effective interventions that address risk factors of non-communicable diseases (NCDs). However, country responses to the implementation of these have been slow and undocumented. The aim of this study was to identify and understand challenges and enablers for the implementation of WHO 'Best buys' for risk factors of diabetes and hypertension in South Africa (SA).

Methods

a mixed methods research with a sequential dominant status design was used starting with a document review to take stock of WHO 'Best buys' in policy in SA. A qualitative study using key informant interviews was then done to identify and understand challenges and enablers for implementation. A triangulation approach for the analysis of both document review and qualitative data was used.

Results

SA has made good progress in including the WHO 'Best buys' in the policy. However, several challenges hamper the successful implementation. Most challenges were related to upstream policy implementation processes such as competing interests of actors, lack of balance between economic vs health gains, and lack of funding. Enabling factors included multi-sectoral engagement and collaboration; community ownership and empowerment; building partnerships for co-creation of enabling environments; leveraging on the existing infrastructure of other health programs; contextualization of policies and programs; and political will and leadership.

Conclusion

SA has made good progress in including WHO 'Best buys' targeting risk factors of diabetes and hypertension in policy, however, various contextual barriers influence effective implementation. Hence, there is a need to leverage enabling factors to foster the implementation of WHO 'Best buys' interventions targeting risk factors of diabetes and hypertension in South Africa.

Cervical cancer prevention in Africa: A policy analysis

BACKGROUND

Cervical cancer is a major public health challenge in Africa. We analyzed the presence and content of policies for the primary, secondary and tertiary prevention of cervical cancer in Africa, to identify areas of opportunity for policy strengthening in the region most affected by cervical cancer globally.

METHODS

We searched for publicly-available policy documents among countries in Africa. Using a data extraction form, we gathered data from these policies about key elements of primary, secondary and tertiary prevention approaches and activities based on World Health Organization (WHO) guidelines. We also contacted key stakeholders in each country to confirm these details. We summarized each country's policy details (summed score for each prevention stage and overall), and compared these scores across individual countries and groups of countries based on economic, policy and public health characteristics.

RESULTS

Most countries had at least one policy addressing some aspect of cervical cancer prevention. Primary and secondary prevention were more commonly addressed, and certain details like age of vaccination, screening age/interval and method, were frequently mentioned in these policies.

CONCLUSION

Countries with high HIV burden and relatively more donor financing for health had more comprehensive cervical cancer policies; there was no apparent association with cervical cancer mortality, female representation in government, or economic indicators (poverty prevalence or income inequality).

POLICY SUMMARY

There is room to improve cervical cancer policy comprehensiveness in Africa, and to bring these policies in line with evidence and expert recommendations. This analysis is timely given upcoming monitoring of the WHO Global Strategy to Accelerate the Elimination of Cervical Cancer as a Public Health Problem. These findings suggest some improvements in African cervical cancer policy, including increased inclusion of vaccination, but many topics remain under-specified. The influence of internal and external factors on policymaking should also be considered.

Population-level interventions targeting risk factors of diabetes and hypertension in South Africa: a document review

BACKGROUND

South Africa bears an increasing burden of non-communicable diseases (NCDs), particularly diabetes, cardiovascular diseases, and cancer. The objective of this study was to identify which population-level interventions, implemented at the level of governmental or political jurisdictions only, targeting risk factors of diabetes and hypertension were included in policies in South Africa. We also looked at whether these have been implemented or not.

METHODS

A review of relevant reports, journal articles, and policy documents was conducted. Documentation from government reports that contains information regarding the planning, implementation and evaluation of population-level interventions targeting diabetes and hypertension were considered, and various databases were searched. The identified population-level interventions were categorized as supportive policies, supportive programs and enabling environments according to the major risk factors of NCDs i.e., tobacco use, harmful consumption of alcohol, unhealthy diet/nutrition and physical inactivity, in accordance with the WHO 'Best buys'. A content document analysis was conducted.

RESULTS

The source documents reviewed included Acts and laws, regulations, policy documents, strategic plans, case studies, government reports and editorials. South Africa has a plethora of policies and regulations targeting major risk factors for diabetes and hypertension implemented in line with WHO 'Best buys' since 1990. A total of 28 policies, legislations, strategic plans, and regulations were identified - 8 on tobacco use; 7 on harmful consumption of alcohol; 8 on unhealthy diet and 5 on physical inactivity - as well as 12 case studies, government reports and editorials. There is good progress in policy formulation in line with the 'Best buys'. However, there are some gaps in the implementation of these policies and programs.

CONCLUSION

Curbing the rising burden of NCDs requires comprehensive strategies which include population-level interventions targeting risk factors for diabetes and hypertension and effective implementation with robust evaluation to identify successes and ways to overcome challenges.

Epidemiology and management of asthma and atopic dermatitis in Sub-Saharan Africa

Sub-Saharan Africa (SSA) is currently undergoing a transformation process of unprecedented magnitude owing to economic development and urbanization. This process is paralleled by a dramatic increase in prevalence and incidence of noncommunicable diseases. In this article we analyze the current situation with regard to 1 group of the earliest noncommunicable diseases in a person's life, namely, allergies and asthma. This article provides an update on the epidemiology, availability, and access to management strategies by patients experiencing bronchial asthma or atopic dermatitis in SSA. Despite all of the progress, there is still a tremendous need to support education and training, transfer of resources, and cooperation with pharmaceutical and diagnostic companies to achieve adequate treatment and sustainability in SSA with regard to allergy, asthma, and eczema management.

Prioritizing Health-Sector Interventions for Noncommunicable Diseases and Injuries in Low- and Lower-Middle Income Countries: National NCDI Poverty Commissions

Noncommunicable Disease and Injury (NCDI) Poverty Commissions in 16 low- and middle-income countries provided evidence-based recommendations on a local, expanded set of priority NCDIs and health-sector interventions needed in national initiatives to attain universal health coverage. These commissions provide a collective platform for policy, research, and advocacy efforts to improve coverage of cost-effective and equitable health-sector interventions for populations living in extreme poverty.

Health sector priorities and interventions to prevent and manage noncommunicable diseases and injuries (NCDIs) in low- and lower-middle-income countries (LLMICs) have primarily adopted elements of the World Health Organization Global Action Plan for NCDs 2013–2020. However, there have been limited efforts in LLMICs to prioritize among conditions and health-sector interventions for NCDIs based on local epidemiology and contextually relevant risk factors or that incorporate the equitable distribution of health outcomes. The Lancet Commission on Reframing Noncommunicable Diseases and Injuries for the Poorest Billion supported national NCDI Poverty Commissions to define local NCDI epidemiology, determine an expanded set of priority NCDI conditions, and recommend cost-effective, equitable health-sector interventions. Fifteen national commissions and 1 state-level commission were established from 2016–2019. Six commissions completed the prioritization exercise and selected an average of 25 NCDI conditions; 15 conditions were selected by all commissions, including asthma, breast cancer, cervical cancer, diabetes mellitus type 1 and 2, epilepsy, hypertensive heart disease, intracerebral hemorrhage, ischemic heart disease, ischemic stroke, major depressive disorder, motor vehicle road injuries, rheumatic heart disease, sickle cell disorders, and subarachnoid hemorrhage. The commissions prioritized an average of 35 health-sector interventions based on cost-effectiveness, financial risk protection, and equity-enhancing rankings. The prioritized interventions were estimated to cost an additional US$4.70–US$13.70 per capita or approximately 9.7%–35.6% of current total health expenditure (0.6%–4.0% of current gross domestic product). Semistructured surveys and qualitative interviews of commission representatives demonstrated positive outcomes in several thematic areas, including understanding NCDIs of poverty, informing national planning and implementation of NCDI health-sector interventions, and improving governance and coordination for NCDIs. Overall, national NCDI Poverty Commissions provided a platform for evidence-based, locally driven determination of priorities within NCDIs.
