Health system challenges of cardiovascular disease and diabetes in four Eastern Mediterranean countries

The Interaction of Diabetes and Tuberculosis: Translating Research to Policy and Practice

Diabetes Mellitus increases the risk of developing Tuberculosis (TB) disease by about three times; it also doubles the risk of death during TB treatment and other poor TB treatment outcomes. Diabetes may increase the risk of latent infection with Mycobacterium tuberculosis (LTBI), but the magnitude of this effect is less clear. Whilst this syndemic has received considerable attention, most of the published research has focussed on screening for undiagnosed diabetes in TB patients or observational follow-up of TB treatment outcomes by diabetes status. There are thus substantial research and policy gaps, particularly with regard to prevention of TB disease in people with diabetes and management of patients with TB-diabetes, both during TB treatment and after successful completion of TB treatment, when they likely remain at high risk of TB recurrence, mortality from TB and cardiovascular disease. Potential strategies to prevent development of TB disease might include targeted vaccination programmes, screening for LTBI and preventive therapy among diabetes patients or, perhaps ideally, improved diabetes management and prevention. The cost-effectiveness of each of these, and in particular how each strategy might compare with targeted TB prevention among other population groups at higher risk of developing TB disease, is also unknown. Despite research gaps, clinicians urgently need practical management advice and more research evidence on the choice and dose of different anti-diabetes medication and effective medical therapies to reduce cardiovascular risks (statins, anti-hypertensives and aspirin). Substantial health system strengthening and integration may be needed to prevent these at risk patients being lost to care at the end of TB treatment.

A critical review of national diabetes prevention and control programs in 12 countries in Middle East

BACKGROUND

Diabetes mellitus has been known as one of the most significant systemic diseases with severe consequences and challenges to human health.

AIM

The primary aim of the current paper was to review the diabetes prevention programs in the Middle East countries, and secondary compare their goals and success rate and conclude possible upcoming strategies.

METHODS

All reports and documents regarding to diabetes prevention and control programs in the region were collected by searching Web of Science, PubMed, MEDLINE, Google Scholar, Scopus and EMBASE for articles up to 2020. The health policy triangle framework was used to analyze diabetes policies and programs. In the Middle East, a shift from rural to urban life, socioeconomic development, sedentary lifestyles, and high fat and sugary foods consumption led to increasing in obesity and diabetes rate, which have become a real challenge.

RESULTS

To decrease the burden of diabetes, preventive strategies with proper local socio-cultural context are needed. Evaluation of current policies and identifying stakeholders' views can help to improve the current strategies for the prevalence of diabetes and its complications.

CONCLUSIONS

It can provide local and global insight to evidence-informed decision-making for future policy reforms to enhance effectiveness of the program.

A comparison of health indicators and social determinants of health between Israel and the Occupied Palestinian Territories

Despite the proximity and interconnections between Israel and the Occupied Palestinian Territories (oPt), great disparities persist in health status between these two regions. This disparity is seen in infant, child and maternal mortality, life expectancy, mortality rates for leading causes of death and measures of mental well-being. This paper compares health indicators between oPt and Israel and examines the social determinants of health that may be responsible for differences between them. Data on health indicators were obtained from publicly available publications or websites of the World Health Organization and The World Bank, as well as the database of the Global Burden of Disease Project of the Institute of Health Metrics and Evaluation. Data on the social determinants of health were obtained from publications and websites of the United Nations, the World Bank, the U.S. Central Intelligence Agency, Palestinian and Israeli government reports, reports from non-governmental organisations, peer-reviewed studies and news articles. The health disparities are due to a complex mix of factors involving economic conditions, food insecurity, environmental exposures, psychological trauma and stress, and access to health services, most of which can be related directly or indirectly to the Israeli military occupation of oPt.

Context-led capacity building in time of crisis: fostering non-communicable diseases (NCD) research skills in the Mediterranean Middle East and North Africa

Background: This paper examines one EC-funded multinational project (RESCAP-MED), with a focus on research capacity building (RCB) concerning non-communicable diseases (NCDs) in the Mediterranean Middle East and North Africa. By the project’s end (2015), the entire region was engulfed in crisis.

Objective: Designed before this crisis developed in 2011, the primary purpose of RESCAP-MED was to foster methodological skills needed to conduct multi-disciplinary research on NCDs and their social determinants. RESCAP-MED also sought to consolidate regional networks for future collaboration, and to boost existing regional policy engagement in the region on the NCD challenge. This analysis examines the scope and sustainability of RCB conducted in a context of intensifying political turmoil.

Methods: RESCAP-MED linked two sets of activities. The first was a framework for training early- and mid-career researchers through discipline-based and writing workshops, plus short fellowships for sustained mentoring. The second integrated public-facing activities designed to raise the profile of the NCD burden in the region, and its implications for policymakers at national level. Key to this were two conferences to showcase regional research on NCDs, and the development of an e-learning resource (NETPH).

Results: Seven discipline-based workshops (with 113 participants) and 6 workshops to develop writing skills (84 participants) were held, with 18 fellowship visits. The 2 symposia in Istanbul and Beirut attracted 280 participants. Yet the developing political crisis tagged each activity with a series of logistical challenges, none of which was initially envisaged. The immediacy of the crisis inevitably deflected from policy attention to the challenges of NCDs.

Conclusions: This programme to strengthen research capacity for one priority area of global public health took place as a narrow window of political opportunity was closing. The key lessons concern issues of sustainability and the paramount importance of responsively shaping a context-driven RCB.

What influenced provision of non-communicable disease healthcare in the Syrian conflict, from policy to implementation? A qualitative study

BACKGROUND

There has been increasing focus on tackling the growing burden of non-communicable diseases (NCD) in crisis settings. The complex and protracted crisis in Syria is unfolding against a background of increasing NCD burden. This study investigated factors influencing implementation of NCD healthcare in Syria.

METHODS

This is a qualitative study, whereby semi-structured interviews were conducted with fourteen humanitarian health staff working on NCD healthcare in Syria.

RESULTS

Challenges to NCD care implementation were reflected at several stages, from planning services through to healthcare delivery. There was a lack of information on unmet population need; little consensus among humanitarian actors regarding an appropriate health service package; and no clear approach for prioritising public health interventions. The main challenges to service delivery identified by participants were conflict-related insecurity and disruption to infrastructure, hampering continuity of chronic illness care. Collaboration was a key factor which influenced implementation at all stages.

CONCLUSIONS

The historical context, the conflict situation, and the characteristics of health actors and their relationships, all impacted provision of NCD care. These factors influenced each other, so that the social views and values (of individuals and organisations), as well as politics and relationships, interacted with the physical environment and security situation. Infrastructure damage has implications for wider healthcare across Syria, and NCD care requires an innovative approach to improve continuity of care. There is a need for a transparent approach to resource allocation, which may be generalisable to the wider humanitarian health sector.

Disease characteristics and treatment of patients with diabetes mellitus attending government health services in Indonesia, Peru, Romania and South Africa

OBJECTIVE

To describe the characteristics and management of Diabetes mellitus (DM) patients from low- and middle-income countries (LMIC).

METHODS

We systematically characterised consecutive DM patients attending public health services in urban settings in Indonesia, Peru, Romania and South Africa, collecting data on DM treatment history, complications, drug treatment, obesity, HbA1c and cardiovascular risk profile; and assessing treatment gaps against relevant national guidelines.

RESULTS

Patients (median 59 years, 62.9% female) mostly had type 2 diabetes (96%), half for >5 years (48.6%). Obesity (45.5%) and central obesity (females 84.8%; males 62.7%) were common. The median HbA1c was 8.7% (72 mmol/mol), ranging from 7.7% (61 mmol/mol; Peru) to 10.4% (90 mmol/mol; South Africa). Antidiabetes treatment included metformin (62.6%), insulin (37.8%), and other oral glucose-lowering drugs (34.8%). Disease complications included eyesight problems (50.4%), EGFR <60 ml/min (18.9%), heart disease (16.5%) and proteinuria (14.7%). Many had an elevated cardiovascular risk with elevated blood pressure (36%), LDL (71.0%) and smoking (13%), but few were taking antihypertensive drugs (47.1%), statins (28.5%) and aspirin (30.0%) when indicated. Few patients on insulin (8.0%), statins (8.4%) and antihypertensives (39.5%) reached treatment targets according to national guidelines. There were large differences between countries in terms of disease profile and medication use.

CONCLUSION

DM patients in government clinics in four LMIC with considerable growth of DM have insufficient glycaemic control, frequent macrovascular and other complications, and insufficient preventive measures for cardiovascular disease. These findings underline the need to identify treatment barriers and secure optimal DM care in such settings.

Defining a Research Agenda to Address the Converging Epidemics of Tuberculosis and Diabetes: Part 1: Epidemiology and Clinical Management

There is growing interest in the interaction between type 2 diabetes mellitus (DM) and TB, but many research questions remain unanswered. Epidemiologists, basic scientists, and clinical experts recently convened and identified priorities. This is the first of two reviews on this topic, summarizing priority areas of research regarding epidemiology, clinical management, and public health. First, from an epidemiologic point of view, more study is needed to determine the importance of transient hyperglycemia in patients with TB and on the importance of DM for the global epidemic of multidrug resistant (MDR)-TB. Second, regarding the screening and clinical management of combined TB and DM (TB-DM), clinical trials and large cohort studies should examine the benefits of improved DM care as well as prolonged or intensified TB treatment on the outcome of TB-DM and investigate the cost-effectiveness of screening methods for DM among patients newly diagnosed with TB. Third, from a public health and health systems point of view, the population health impact and cost-effectiveness of different interventions to prevent or treat DM and TB in high-burden populations should be examined, and health-system interventions should be developed for routine TB-DM screening, management of DM after completion of TB treatment, and better access to DM services worldwide. Studies are needed across different ethnicities and settings given the heterogeneity of metabolic perturbations, inflammatory responses, medications, and access to health care. Finally, studies should address interactions between TB, DM, and HIV because of the convergence of epidemics in sub-Saharan Africa and some other parts of the world.

Contrasting cardiovascular mortality trends in Eastern Mediterranean populations: Contributions from risk factor changes and treatments

BACKGROUND

Middle income countries are facing an epidemic of non-communicable diseases, especially coronary heart disease (CHD). We used a validated CHD mortality model (IMPACT) to explain recent trends in Tunisia, Syria, the occupied Palestinian territory (oPt) and Turkey.

METHODS

Data on populations, mortality, patient numbers, treatments and risk factor trends from national and local surveys in each country were collated over two time points (1995-97; 2006-09); integrated and analysed using the IMPACT model.

RESULTS

Risk factor trends: Smoking prevalence was high in men, persisting in Syria but decreasing in Tunisia, oPt and Turkey. BMI rose by 1-2 kg/m(2) and diabetes prevalence increased by 40%-50%. Mean systolic blood pressure and cholesterol levels increased in Tunisia and Syria. Mortality trends: Age-standardised CHD mortality rates rose by 20% in Tunisia and 62% in Syria. Much of this increase (79% and 72% respectively) was attributed to adverse trends in major risk factors, occurring despite some improvements in treatment uptake. CHD mortality rates fell by 17% in oPt and by 25% in Turkey, with risk factor changes accounting for around 46% and 30% of this reduction respectively. Increased uptake of community treatments (drug treatments for chronic angina, heart failure, hypertension and secondary prevention after a cardiac event) accounted for most of the remainder.

DISCUSSION

CHD death rates are rising in Tunisia and Syria, whilst oPt and Turkey demonstrate clear falls, reflecting improvements in major risk factors with contributions from medical treatments. However, smoking prevalence remains very high in men; obesity and diabetes levels are rising dramatically.

Health system challenges of NCDs in Tunisia

OBJECTIVES

The objective of this study was to present a qualitative 'situation analysis' of the healthcare system in Tunisia, as it applies to management of cardiovascular disease (CVD) and diabetes. A primary concern was the institutional capacity to manage non-communicable diseases (NCDs).

METHODS

Research took place during 2010 (analysis of official documents, semi-structured interviews with key informants, and case studies in four clinics). Walt and Gilson's framework (1994) for policy analysis was used: content, actors, context, and process.

RESULTS

Problems of integration and coordination have compounded funding pressures. Despite its importance in Tunisian healthcare, primary health is ill-equipped to manage NCDs. With limited funds, and no referral or health information system, staff morale in the public sector was low. Private healthcare has been the main development filling the void.

CONCLUSION

This study highlights major gaps in the implementation of a comprehensive approach to NCDs, which is an urgent task across the region. In strategic planning, research on the health system is vital; but the capacity within Ministries of Health to use research has first to be built, with a commitment to grounding policy change in evidence.

Research capacity and training needs for non-communicable diseases in the public health arena in Turkey

Background

The aim of this study is to define the research capacity and training needs for professionals working on non-communicable diseases (NCDs) in the public health arena in Turkey.

Methods

This study was part of a comparative cross-national research capacity-building project taking place across Turkey and the Mediterranean Middle East (RESCAP-Med, funded by the EU). Identification of research capacity and training needs took place in three stages. The first stage involved mapping health institutions engaged in NCD research, based on a comprehensive literature review. The second stage entailed in-depth interviews with key informants (KIs) with an overview of research capacity in public health and the training needs of their staff. The third stage required interviewing junior researchers, identified by KIs in stage two, to evaluate their perceptions of their own training needs. The approach we have taken was based upon a method devised by Hennessy&Hicks. In total, 55 junior researchers identified by 10 KIs were invited to participate, of whom 46 researchers agreed to take part (84%). The specific disciplines in public health identified in advance by RESCAP-MED for training were: advanced epidemiology, health economics, environmental health, medical sociology-anthropology, and health policy.

Results

The initial literature review showed considerable research on NCDs, but concentrated in a few areas of NCD research. The main problems listed by KIs were inadequate opportunities for specialization due to heavy teaching workloads, the lack of incentives to pursue research, a lack of financial resources even when interest existed, and insufficient institutional mechanisms for dialogue between policy makers and researchers over national research priorities. Among junior researchers, there was widespread competence in basic epidemiological skills, but an awareness of gaps in knowledge of more advanced epidemiological skills, and the opportunities to acquire these skills were lacking. Self-assessed competencies in each of the four other disciplines considered revealed greater training needs, especially regarding familiarity with the qualitative research skills for medical anthropology/sociology.

Conclusions

In Turkey there are considerable strengths to build upon. But a combination of institutional disincentives for research, and the lack of opportunities for the rising generation of researchers to acquire advanced training skills.

Health system challenges for the management of cardiovascular disease and diabetes: an empirical qualitative study from Syria

OBJECTIVES

To explore through empirical qualitative data health system barriers to effective management of cardiovascular disease and diabetes in Syria before the crisis, and how such analysis can inform the building of a post-crisis system.

METHODS

Data were collected through document review, semi-structured key informant interviews, and fieldwork in clinics.

RESULTS

Institutional commitment to address the increasing burden of CVD and diabetes in Syria was limited and uncoordinated. Challenges included an increasingly split healthcare system, with private provision for those who could afford it, and a residual state health sector for the majority. Public trust in the system had been declining.

CONCLUSIONS

We conclude that lack of effective management of CVD and diabetes indicated weaknesses of the state and its retracting role in providing effective healthcare. Such weaknesses that existed before the crisis are now compounded by new challenges resulting from wide destruction of the health system due to the ongoing war. The rebuilding of post-conflict heath care system may benefit from insights into the structural problems of the pre-crisis system.

Living with diabetes and hypertension in Tunisia: popular perspectives on biomedical treatment

OBJECTIVES

The growing prevalence of non-communicable diseases across the Middle East and North Africa poses major challenges for underfunded health services. This article presents data on the perspectives of ordinary Tunisians who are coping with two of these diseases--diabetes and hypertension--and who are obtaining treatment through Tunisian public health clinics. Little has been written to date on patient experiences of biomedical treatment in Maghreb countries.

METHODS

Based on qualitative methods and semi-structured interviews with 24 patients attending two clinics, one urban and one rural.

RESULTS

We examine popular aetiological beliefs, ideas about biomedical treatment and its implications, and comparative views on the benefits and drawbacks of treatment in both public and private clinics.

CONCLUSIONS

We highlight two main themes. One was nostalgia for a recent past when 'pure' and 'natural' food, 'proper' meals and less stressful lives meant less chronic illness, with demanding and costly treatment. The other concerned communication in the clinic, and the recurrent dismay patients felt at what they saw as the cursory attention and guidance they received from clinic staff in public facilities.

Priority setting for the prevention and control of cardiovascular diseases: multi-criteria decision analysis in four eastern Mediterranean countries

OBJECTIVES

To explore the feasibility of using a simple multi-criteria decision analysis method with policy makers/key stakeholders to prioritize cardiovascular disease (CVD) policies in four Mediterranean countries: Palestine, Syria, Tunisia and Turkey.

METHODS

A simple multi-criteria decision analysis (MCDA) method was piloted. A mixed methods study was used to identify a preliminary list of policy options in each country. These policies were rated by different policymakers/stakeholders against pre-identified criteria to generate a priority score for each policy and then rank the policies.

RESULTS

Twenty-five different policies were rated in the four countries to create a country-specific list of CVD prevention and control policies. The response rate was 100% in each country. The top policies were mostly population level interventions and health systems' level policies.

CONCLUSIONS

Successful collaboration between policy makers/stakeholders and researchers was established in this small pilot study. MCDA appeared to be feasible and effective. Future applications should aim to engage a larger, representative sample of policy makers, especially from outside the health sector. Weighting the selected criteria might also be assessed.
