Systemic Solutions for Addressing Non-Communicable Diseases in Low- and Middle-Income Countries

On-demand mobile hypertension training for primary health care workers in Nigeria: a pilot study

BACKGROUND

Only one out of every ten Nigerian adults with hypertension has their blood pressure controlled. Health worker training is essential to improve hypertension diagnosis and treatment. In-person training has limitations that mobile, on-demand training might address. This pilot study evaluated a self-paced, case-based, mobile-optimized online training to diagnose and manage hypertension for Nigerian health workers.

METHODS

Twelve hypertension training modules were developed, based on World Health Organization and Nigerian guidelines. After review by local academic and government partners, the course was piloted by Nigerian health workers at government-owned primary health centers. Primary care physician, nurse, and community health worker participants completed the course on their own smartphones. Before and after the course, hypertension knowledge was evaluated with multiple-choice questions. Learners provided feedback by responding to questions on a Likert scale.

RESULTS

Out of 748 users who sampled the course, 574 enrolled, of whom 431 (75%) completed the course. The average pre-test score of completers was 65.4%, which increased to 78.2% on the post-test (P < 0.001, paired t-test). Health workers who were not part of existing hypertension control programs had lower pre-test scores and larger score gains. Most participants (96.1%) agreed that the training was applicable to their work, and nearly all (99.8%) agreed that they enjoyed the training.

CONCLUSIONS

An on-demand mobile digital hypertension training increases knowledge of hypertension management among Nigerian health workers. If offered at scale, such courses can be a tool to build health workforce capacity through initial and refresher training on current clinical guidelines in hypertension and other chronic diseases in Nigeria as well as other countries.

The role of the private sector in noncommunicable disease prevention and management in low- and middle-income countries: a series of systematic reviews and thematic syntheses

PURPOSE

Conduct six systematic reviews investigating for-profit private sector roles in NCD prevention and management in low- and middle-income countries (LMICs) through our a priori framework's pillars.

METHODS

Six systematic reviews and thematic syntheses were performed between March-August 2021, Six databases, websites of relevant organizations, and references lists of included studies were comprehensively searched. Studies published in English from 2000 onwards involving the pillar of interest, for-profit private sector, NCD prevention/management, and LMIC context were included. Results were synthesized using an inductive thematic synthesis approach.

RESULTS

Ultimately, 25 articles were included in the PPP review, 33 in Governance and Policy, 22 in Healthcare Provision, 15 in Innovation, 14 in Knowledge Educator, and 42 in Investment and Finance. The following themes emerged: PPPs (coordination; financial resources; provision; health promotion; capacity building; innovation; policy); Governance/Policy (lobbying; industry perception; regulation); Healthcare Provision (diagnosis/treatment; infrastructure; availability/accessibility/affordability); Innovation (product innovation; process innovation; marketing innovation; research; innovation dissemination); Knowledge Educator (training; health promotion; industry framework/guideline formation); Investment and Finance (treatment cost; regulation; private insurance; subsidization; direct investment; collaborative financing; innovative financing; research).

CONCLUSION

These findings will be instrumental for LMICs considering private sector engagement. Potential conflicts of interest must be considered when implementing private sector involvement.

Assessment of the WHO non-communicable diseases kit for humanitarian emergencies in South Sudan: a retrospective, prospective, observational study

BACKGROUND

The WHO Non-Communicable Diseases Kit (NCDK) was developed to support care for non-communicable diseases (NCDs) in humanitarian settings. Targeting primary healthcare, each kit contains medicines and supplies that are forecasted to meet the needs of 10,000 people for 3 months. This study aimed to evaluate the NCDK deployment process, contents, usage and limitations, and to explore its acceptability and effectiveness among healthcare workers (HCWs) in South Sudan.

METHODS

This mixed-method observational study captured data from pre-and-post NCDK deployment. Six data collection tools included: (i) contextual analysis, (ii) semi-structured interviews, in addition to surveys measuring/assessing (iii) healthcare workers' knowledge about NCDs, and healthcare workers' perceptions of: (iv) health facility infrastructure, (v) pharmaceutical supply chain, and (vi) NCDK content. The pre- and post-deployment evaluations were conducted in four facilities (October-2019) and three facilities (April-2021), respectively. Descriptive statistics were used for quantitative data and content analysis for open-ended questions. A thematic analysis was applied on interviews findings and further categorized into four predetermined themes.

RESULTS

Compared to baseline, two of the re-assessed facilities had improved service availability for NCDs. Respondents described NCDs as a growing problem that is not addressed at a national level. After deployment, the same struggles were intensified with the COVID-19 pandemic. The delivery process was slow and faced delays associated with several barriers. After deployment, poor communications and the "push system" of inventories were commonly perceived by stakeholders, leading to expiry/disposal of some contents. Despite being out-of-stock at baseline, at least 55% of medicines were found to be unused post-deployment and the knowledge surveys demonstrated a need for improving HCWs knowledge of NCDs.

CONCLUSIONS

This assessment further confirmed the NCDK role in maintaining continuity of care on a short-term period. However, its effectiveness was dependent on the health system supply chain in place and the capacity of facilities to manage and treat NCDs. Availability of medicines from alternative sources made some of the NCDK medicines redundant or unnecessary for some health facilities. Several learnings were identified in this assessment, highlighting barriers that contributed to the kit underutilization.

Potential Gains in Health-Adjusted Life Expectancy by Reducing Burden of Noncommunicable Diseases in 188 Countries: A Population-Based Study

OBJECTIVES

This article quantifies the potential gains in health-adjusted life expectancy for people aged 30 to 70 years (HALE_[30-70]) by examining the reductions in disability in addition to premature mortality from noncommunicable diseases (NCDs).

METHODS

We extracted data from the Global Burden of Disease Study 2019 for 4 major NCDs (cancers, cardiovascular diseases, chronic respiratory diseases, and diabetes mellitus) in 188 countries from 2010 to 2019. Estimates of the potential gains in HALE_[30-70] were based on a counterfactual analysis involving 3 alternative future scenarios: (1) achieve Sustainable Development Goals target 3.4 but do not make any progress on disability reduction, (2) achieve Sustainable Development Goals target 3.4 and eliminate NCD-related disability, and (3) eliminate all NCD-related mortality and disability.

RESULTS

In all scenarios, the high-income group has the greatest potential gains in HALE_[30-70], above the global average. For all specific causes, potential gains in HALE_[30-70] decrease as income levels fall. Across these 3 scenarios, the potential gains in HALE_[30-70] globally of reducing premature mortality for 4 major NCDs are 3.13 years, 4.53 years, and 7.32 years, respectively. In scenario A, all income groups have the greatest potential gains in HALE_[30-70] from diabetes and chronic respiratory diseases. In scenarios B and C, the high-income group has the greatest potential gains in HALE_[30-70] from cancer intervention, and the other income groups have the greatest potential gains in HALE_[30-70] from cardiovascular diseases intervention.

CONCLUSION

Reducing premature death and disability from 4 major NCDs at once and attaching equal importance to each lead to a sizable improvement in HALE_[30-70].

Inequalities in successful tobacco cessation and tobacco cessation attempts: Evidence from eight Sub-Saharan African countries

BACKGROUND

Tobacco consumption is a contributing and modifiable risk factor for non-communicable diseases. In high-income countries, tobacco cessation attempts, and their success, are concentrated among the socio-economically advantaged, resulting in a skewed burden of disease. However, there is a paucity of evidence on the distribution of tobacco cessation in low- and middle-income countries.

OBJECTIVE

The objective of this study is to measure and decompose wealth- and education-related inequalities in tobacco cessation in eight Sub-Saharan African countries.

METHODOLOGY

The study applies Erreygers' corrected concentration indices and decomposition methods to the most recent Global Adult Tobacco Surveys in Botswana, Cameroon, Ethiopia, Kenya, Nigeria, Senegal, Tanzania, and Uganda.

FINDINGS

We find that across countries, successful tobacco cessation, as well as tobacco cessation attempts, are concentrated among wealthier and better-educated individuals. Differences in socio-economic status, urban or rural residence, and not knowing or believing that tobacco consumption leads to serious illness contributes to these inequalities.

CONCLUSION

Governments in our sample of countries can do more to support socio-economically disadvantaged smokers in their efforts to quit smoking, including by making an effort to align each country's smoking cessation strategy with the guidelines outlined in the World Health Organization's Framework Convention on Tobacco Control.

Research protocol for impact assessment of a project to scale up food policies in the Pacific

Background

One of the challenges for countries implementing food policy measures has been the difficulty in demonstrating impact and retaining stakeholder support. Consequently, research funded to help countries overcome these challenges should assess impact and translation into practice, particularly in low-resource settings. However, there are still few attempts to prospectively, and comprehensively, assess research impact. This protocol describes a study co-created with project implementers, collaborative investigators and key stakeholders to optimize and monitor the impact of a research project on scaling up food policies in Fiji.

Methods

To develop this protocol, our team of researchers prospectively applied the Framework to Assess the Impact from Translational health research (FAIT). Activities included (i) developing a logic model to map the pathway to impact and establish domains of benefit; (ii) identifying process and impact indicators for each of these domains; (iii) identifying relevant data for impact indicators and a cost–consequence analysis; and (iv) establishing a process for collecting quantitative and qualitative data to measure progress. Impact assessment data will be collected between September 2022 and December 2024, through reports, routine monitoring activities, group discussions and semi-structured interviews with key implementers and stakeholders. The prospective application of the protocol, and interim and final research impact assessments of each project stream and the project as a whole, will optimize and enable robust measurement of research impact.

Discussion

By applying this protocol, we aim to increase understanding of pathways to impact and processes that need to be put in place to achieve this. This impact evaluation will inform future projects with a similar scope and will identify transferable and/or translatable lessons for other Pacific Island states and low- and middle-income countries.

The burden of risk factors for non-communicable disease in rural Bihar, India: a comparative study with national health surveys

BACKGROUND

The incidence of non-communicable diseases (NCDs) is increasing in rural India. The National Family Health Survey-5 (NFHS-5) provides estimates of the burden of NCDs and their risk factors in women aged 15-49 and men aged 15-54 years. The aim of this study is to estimate the prevalence of hypertension and body-mass index (BMI) in adults aged 35-70 years in rural India and to compare these estimates, where age ranges overlap, to routinely available data.

METHODS

The Non-Communicable Disease in Rural India (NCDRI) Study was a cross-sectional household survey of 1005 women and 1025 men aged 35-70 conducted in Bihar in July 2019. Information was collected on personal characteristics, self-reported medical history and physical measurements (blood pressure, height and weight). Prevalence estimates for hypertension (systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg, or diagnosed and treated for hypertension), and for underweight (body-mass index < 18.5 kg/m²), normal weight (18.5-25.0 kg/m²) and overweight (≥ 25.0 kg/m²) were calculated. Where age ranges overlapped, estimates from the NCDRI Study were compared to the NFHS-5 Survey.

RESULTS

In the NCDRI Study, the estimated prevalence of hypertension was 27.3% (N = 274) in women and 27.6% (N = 283) in men aged 35-70, which was three-times higher in women and over two-times higher in men than in the NFHS-5 Survey. One-quarter (23.5%; N = 236) of women and one-fifth (20.2%; N = 207) of men in the NCDRI Study were overweight, which was approximately 1.5 times higher than in the NFHS-5 Survey. However, where age groups overlapped, similar age-standardized estimates were obtained for hypertension and weight in both the NCDRI Study and the NFHS-5 Survey.

CONCLUSION

The prevalence of NCDs in rural India is higher than previously reported due to the older demographic in our survey. Future routine national health surveys must widen the age range of participants to reflect the changing disease profile of rural India, and inform the planning of health services.

Factors Influencing the Implementation of Remote Delivery Strategies for Non-Communicable Disease Care in Low- and Middle-Income Countries: A Narrative Review

Objectives: The COVID-19 pandemic has disrupted health care for non-communicable diseases (NCDs) and necessitated strategies to minimize contact with facilities. We aimed to examine factors influencing implementation of remote (non-facility-based) delivery approaches for people with hypertension and/or diabetes in low- and middle-income countries (LMICs), to inform NCD care delivery during health service disruption, including humanitarian crises.

Methods: Our narrative review used a hermeneutic and purposive approach, including primary studies conducted in LMICs, which assessed implementation factors influencing remote NCD care delivery. Results were analyzed using the Consolidated Framework for Implementation Research.

Results: Twenty-eight included studies revealed the strong influence of both internal organizational and broader contextual factors, such as community health worker policies or technological environment. Addressing patients’ specific characteristics, needs and resources was important for implementation success.

Conclusion: This review highlighted the multiple, complex, interdependent factors influencing implementation of remote NCD care in LMICs. Our findings may inform actors designing NCD care delivery in contexts where facility-based access is challenging. Implementation research is needed to evaluate context-adapted e-Health, community-based, and simplified clinical management strategies to facilitate remote NCD care.

Implementing effective salt reduction programs and policies in low- and middle-income countries: learning from retrospective policy analysis in Argentina, Mongolia, South Africa and Vietnam

OBJECTIVE

To understand the factors influencing the implementation of salt reduction interventions in low- and middle-income countries (LMIC).

DESIGN

Retrospective policy analysis based on desk reviews of existing reports and semi-structured stakeholder interviews in four countries, using Walt and Gilson's 'Health Policy Triangle' to assess the role of context, content, process and actors on the implementation of salt policy.

SETTING

Argentina, Mongolia, South Africa and Vietnam.

PARTICIPANTS

Representatives from government, non-government, health, research and food industry organisations with the potential to influence salt reduction programmes.

RESULTS

Global targets and regional consultations were viewed as important drivers of salt reduction interventions in Mongolia and Vietnam in contrast to local research and advocacy, and support from international experts, in Argentina and South Africa. All countries had population-level targets and written strategies with multiple interventions to reduce salt consumption. Engaging industry to reduce salt in foods was a priority in all countries: Mongolia and Vietnam were establishing voluntary programs, while Argentina and South Africa opted for legislation on salt levels in foods. Ministries of Health, the WHO and researchers were identified as critical players in all countries. Lack of funding and technical capacity/support, absence of reliable local data and changes in leadership were identified as barriers to effective implementation. No country had a comprehensive approach to surveillance or regulation for labelling, and mixed views were expressed about the potential benefits of low sodium salts.

CONCLUSIONS

Effective scale-up of salt reduction programs in LMIC requires: (1) reliable local data about the main sources of salt; (2) collaborative multi-sectoral implementation; (3) stronger government leadership and regulatory processes and (4) adequate resources for implementation and monitoring.

The Impact of COVID-19 on the Care of Patients With Noncommunicable Diseases in Low- and Middle-Income Countries: An Online Survey of Patient Perspectives

We sought to gain insights into the impacts of COVID-19 and associated control measures on health and health care of patients from low- and middle-income countries with cardiovascular disease, diabetes, and mental health conditions, using an online survey during the COVID-19 pandemic. The most common concern for the 1487 patients who took part was contracting COVID-19 when they accessed health care. Of those infected with COVID-19, half said that their health had been worse since being infected. Collectively, most people reported an increase in feelings of stress and loneliness. The COVID-19 pandemic has led to a range of health care impacts on patients with noncommunicable diseases, including constraints on access to care and health effects, particularly mental well-being.

Socioeconomic status and tobacco consumption: Analyzing inequalities in China, Ghana, India, Mexico, the Russian Federation and South Africa

INTRODUCTION

Globally, there has been a rapid rise in non-communicable diseases driven by changing lifestyle choices and health behaviors. Different lifestyle choices threaten to exacerbate existing health inequalities, yet evidence monitoring the extent of this impact in emerging economies is lacking. The article sets out to measure the level of wealth-related inequality and its drivers in one of these lifestyle choices, tobacco consumption, among populations aged ≥50 years in six Low- and Middle-Income Countries.

METHODS

The study provides empirical evidence of the inequality in tobacco consumption across wealth groups in China, Ghana, India, Mexico, the Russian Federation and South Africa using the Erreygers’ corrected concentration indices. These inequalities are then decomposed to gain a deeper understanding of the factors and broader social forces driving inequality. The WHO SAGE data set, collected between 2008 and 2010, is used for the analysis.

RESULTS

Current tobacco consumption is concentrated among the poor in China, Ghana, India, and South Africa, and among the wealthy in the Russian Federation and Mexico. The inequalities widen when we focus solely on the male population. Although the results differ by country, the major drivers of inequality include wealth, locality, and gender.

CONCLUSIONS

The focus on tobacco consumption in this age group is key to curbing rising healthcare costs and ensuring longevity. Policies aimed at reducing wealth-related inequalities should especially target high tobacco consumption rates among males, while simultaneously pre-empting and curbing rising rates among women.

The impact of COVID-19 on the care of people living with noncommunicable diseases in low- and middle-income countries: an online survey of physicians and pharmacists in nine countries

BACKGROUND

The global COVID-19 pandemic has disrupted healthcare worldwide. In low- and middle-income countries (LMICs), where people may have limited access to affordable quality care, the COVID-19 pandemic has the potential to have a particularly adverse impact on the health and healthcare of individuals with noncommunicable diseases (NCDs). A World Health Organization survey found that disruption of delivery of healthcare for NCDs was more significant in LMICs than in high-income countries. However, the study did not elicit insights into the day-to-day impacts of COVID-19 on healthcare by front-line healthcare workers (FLHCWs).

AIM

To gain insights directly from FLHCWs working in countries with a high NCD burden, and thereby identify opportunities to improve the provision of healthcare during the current pandemic and in future healthcare emergencies.

METHODS

We recruited selected frontline healthcare workers (general practitioners, pharmacists, and other medical specialists) from nine countries to complete an online survey (n = 1347). Survey questions focused on the impact of COVID-19 pandemic on clinical practice and NCDs; barriers to clinical care during the pandemic; and innovative responses to the many challenges presented by the pandemic.

FINDINGS

The majority of FLHCWs responding to our survey reported that their care of patients had been impacted both adversely and positively by the public health measures imposed. Most FLHCs (95%) reported a deterioration in the mental health of their patients.

CONCLUSIONS

Continuity of care for NCDs as part of pandemic preparedness is needed so that chronic conditions are not exacerbated by public health measures and the direct impacts of the pandemic.

A Narrative Review of the Patient Journey Through the Lens of Non-communicable Diseases in Low- and Middle-Income Countries

Low- and middle-income countries (LMICs) are challenged with a disproportionately high burden of noncommunicable diseases (NCDs) and limited healthcare resources at their disposal to tackle the NCD epidemic. Understanding the patient journey for NCDs from the patients' perspective can help healthcare systems in these settings evolve their NCD care models to address the unmet needs of patients, enhance patient participation in their management, and progress towards better outcomes and quality of life. This paper aims to provide a theoretical framework outlining common touchpoints along the patient journey for NCDs in LMICs. It further aims to review influencing factors and recommend strategies to improve patient experience, satisfaction, and disease outcomes at each touchpoint. The co-occurrence of major NCDs makes it possible to structure the patient journey for NCDs into five broad touchpoints: awareness, screening, diagnosis, treatment, and adherence, with integration of palliative care along the care continuum pathway. The patients' perspective must be considered at each touchpoint in order to inform interventions as they experience first-hand the impact of NCDs on their quality of life and physical function and participate substantially in their disease management. Collaboratively designed health communication programs, shared decision-making, use of appropriate risk assessment tools, therapeutic alliances between the patient and provider for treatment planning, self-management tools, and improved access to palliative care are some strategies to help improve the patient journeys in LMICs. Long-term management of NCDs entails substantial self-management by patients, which can be augmented by pharmacists and nurse-led interventions. The digital healthcare revolution has heralded an increase in patient engagement, support of home monitoring of patients, optimized accurate diagnosis, personalized care plans, and facilitated timely intervention. There is an opportunity to integrate digital technology into each touchpoint of the patient journey, while ensuring minimal interruption to patients' care in the face of global health emergencies.
