Surveillance of Noncommunicable Diseases by Community Health Workers in Kerala: The Epidemiology of Noncommunicable Diseases in Rural Areas (ENDIRA) Study

Task-sharing with community health workers to treat hypertension: a scoping review

Many studies have implemented and evaluated task-sharing interventions with community health workers (CHWs) to manage hypertension. To identify gaps in research, we conducted a scoping review. We searched original articles published in PubMed and EMBASE between 2010 and 2022 and found 122 articles meeting our inclusion criteria. Only seven articles were from low-income countries (LICs), most of which were qualitative studies or mixed methods studies. In the identified 122 articles, CHWs often performed health education (61.3%) and measured blood pressure (60.4%). Whereas CHWs carried out pharmacological treatment in only three studies. Participant homes (75.0%) were the most common setting for receiving interventions. Our study identified specific needs for future research, specifically, studies in LICs that are experimental in design and that collect relevant qualitative information, and studies in which CHWs do advanced task. In addition, publications of CHW studies should provide a more comprehensive list of intervention features.

Healthcare service utilisation among adults with coronary artery disease in rural Aluva, South India: a community-based cross-sectional study

OBJECTIVES

To assess the pattern and determinants of healthcare service utilisation among adults with coronary artery disease (CAD) in a rural setting in Kerala, India.

DESIGN

A community-based cross-sectional analysis conducted within a study cohort.

SETTING

The study was conducted from January 2022 to March 2022 within the ENDIRA Cohort (Epidemiology of Non-communicable Diseases In Rural Areas) in the rural part of Aluva municipality of Ernakulam district, Kerala, India, which comprises five adjacent panchayats with a population of approximately 100, 000 individuals.

PARTICIPANTS

Patients with CAD aged 35-80 years from the ENDIRA cohort with a history of at least one event of myocardial infarction in the past decade.

OUTCOME MEASURES

The main outcome measured was the inadequacy of healthcare service utilisation among patients with CAD. The factors evaluated included age, gender, socioeconomic status, insurance, out of pocket expenses, choice of health care facility for follow up, distance from health centre as well as reported alcohol use, tobacco use and healthcare satisfaction RESULTS: The study encompassed 623 participants with a mean age of 65.12 (±8.55) years, of whom 71% were males. The prevalence of inadequate utilisation of health services was 58.7%. The independent predictors of underutilisation included reported alcohol consumption (adjusted OR (AOR) 2.36; 95% CI 1.41 to 3.95), living more than 20 km from healthcare facilities (AOR 1.96; 95% CI 1.14 to 3.37) as well as the preferences for specific doctors and adequate services at healthcare facilities (AOR 3.43; 95% CI 1.46 to 8.04). The patients with monthly CAD medication expenses exceeding Rs4000 had 0.26 times lesser odds to underuse healthcare services (AOR 0.26; 95% CI 0.10 to 0.65).

CONCLUSION

The study reveals a suboptimal pattern of healthcare service utilisation among patients with CAD. Ensuring community access to standardised, high-quality follow-up care is crucial for enhancing healthcare utilisation following CAD.

The role(s) of community health workers in primary health care reform in Kerala, before and during the COVID 19 pandemic: a qualitative study

Background

Accredited Social Health Activists (ASHA) are Community Health Workers (CHWs) employed by the National Health Mission of the Government of India to link the population to health facilities and improve maternal and child health outcomes in the country. The government of Kerala launched primary health reform measures in 2016 whereby Primary Health Centres (PHCs) were upgraded to Family Health Centres (FHCs). The COVID-19 pandemic in 2020 impacted essential health service delivery, including primary care services. The CHWs network of Kerala played a crucial role in implementing the primary care reforms and COVID-19 management efforts that followed. We carried out a study to understand the perspectives of the CHWs in Kerala about their role in the recent primary healthcare reforms and during the COVID-19 pandemic management efforts.

Methods

We conducted in-depth interviews (IDI) with 16 ASHAs from 8 primary care facilities in Kerala from July to October 2021. We further conducted Focus Group Discussions (FGDs) (N = 34) with population subgroups in these eight facility catchment areas and asked their opinion about the ASHAs working in their community. We obtained written informed consent from all the participants, and interview transcripts were thematically analysed by a team of four researchers using ATLAS.ti 9 software.

Results

Our study participants were women aged about 45 years with over 10 years of work experience as CHWs. Their job responsibilities as a frontline health worker helped them build trust in the community and local self-governments. CHWs were assigned roles of outpatient crowd management, and registration duties in FHCs. The COVID-19 pandemic increased their job roles manifold. Community members positively mentioned the home visits, delivery of medicines, and emotional support offered by the CHWs during the pandemic. The CHWs noted that the honorarium of INR 6,000 (US$73) was inconsistent and very low for the volume of work done.

Conclusion

The CHWs in Kerala play a crucial role in primary care reforms and COVID-19 management. Despite their strong work ethic and close relationship with local self-governments, low and irregular wages remain the biggest challenge.

Intersecting sex-related inequalities in self-reported testing for and prevalence of Non-Communicable Disease (NCD) risk factors in Kerala

BACKGROUND

Non-Communicable Diseases (NCDs) are among India's top burdens, particularly in states like Kerala, which is at an advanced stage of the epidemiological transition. Evidence in India points towards intersectional inequalities in risk factors of NCDs and testing, both of which are understudied in Kerala. We estimated the self-reported testing and prevalence of key NCD risk factors-blood pressure (BP) and blood glucose (BG) comparing Kerala men and women across educational, wealth, religion, as well as caste and tribal status subgroups.

METHOD

A multistage random sample survey of 3398 women and 2982 men aged 30 years and over was administered in 4 districts of Kerala from July to October 2019. Descriptive analysis for men and women was undertaken using survey weights. Slope index of Inequality and Relative Concentration Index for wealth and education related inequalities, and, Weighted Mean Difference from Mean and Index of Disparity for caste and tribal status, as well as religion related inequalities were calculated using World Health Organisation's Health Equity Assessment Toolkit Plus and Stata 12.

RESULTS

A significantly higher proportion of women reported BP and BG testing by medical personnel in the previous year than men (BP Testing among Women (BPT_w): 90.3% vs BP Testing among Men (BPT_M):80.8%, BG Testing among Women (BGT_w): 86.2% vs BG Testing among Women (BGT_M):78.3%). Among those tested, more women (11.2%) than men (7.9%) reported High Blood Pressure (HBP) but not High Blood Glucose (HBG). Testing for BP was concentrated among less-educated women while BG testing was concentrated among both less educated women and men. HBP and HBG were concentrated among less educated and wealthier groups. Although sex differences were insignificant across caste and tribal status and religion subgroups, magnitude of inequalities was high for HBP and HBG.

CONCLUSION

Distinct patterns of sex inequalities were present in self-reported testing and prevalence of NCD risk factors in Kerala. Education and wealth seem to be associated with testing while prevalence appeared to vary by religious groups. Given the low rates of illiteracy, it is encouraging but maybe a data artefact that a small population of less-educated persons was getting tested; however, exclusion of poor groups and inequalities by other dimensions raise concerns. Further exploration is needed to understand underlying mechanisms of these inequalities to ensure we leave no one behind.

Strengthening the role of community health workers in supporting the recovery of ill, undernourished children post hospital discharge: qualitative insights from key stakeholders in Bangladesh and Kenya

BACKGROUND

Undernourished children in low- and middle-income countries remain at elevated risk of death following hospital discharge, even when treated during hospitalisation using World Health Organisation recommended guidelines. The role of community health workers (CHWs) in supporting post-discharge recovery to improve outcomes has not been adequately explored.

METHODS

This paper draws on qualitative research conducted as part of the Childhood Acute Illnesses and Nutrition (CHAIN) Network in Bangladesh and Kenya. We interviewed family members of 64 acutely ill children admitted across four hospitals (a rural and urban hospital in each country). 27 children had severe wasting or kwashiorkor on admission. Family members were interviewed in their homes soon after discharge, and up to three further times over the following six to fourteen months. These data were supplemented by observations in facilities and homes, key informant interviews with CHWs and policy makers, and a review of relevant guidelines.

RESULTS

Guidelines suggest that CHWs could play a role in supporting recovery of undernourished children post-discharge, but the mechanisms to link CHWs into post-discharge support processes are not specified. Few families we interviewed reported any interactions with CHWs post-discharge, especially in Kenya, despite our data suggesting that opportunities for CHWs to assist families post-discharge include providing context sensitive information and education, identification of danger signs, and supporting linkages with community-based services and interventions. Although CHWs are generally present in communities, challenges they face in conducting their roles include unmanageable workloads, few incentives, lack of equipment and supplies and inadequate support from supervisors and some community members.

CONCLUSION

A multi-pronged approach before or on discharge is needed to strengthen linkages between CHWs and children vulnerable to poor outcomes, supported by clear guidance. To encourage scale-ability and cost-effectiveness of interventions, the most vulnerable, high-risk children, should be targeted, including undernourished children. Intervention designs must also take into account existing health worker shortages and training levels, including for CHWs, and how any new tasks or personnel are incorporated into hospital and broader health system hierarchies and systems. Any such interventions will need to be evaluated in carefully designed studies, including tracking for unintended consequences.

Perceptions of ASHA workers in the HOPE collaborative care mental health intervention in rural South India: a qualitative analysis

OBJECTIVE

The main objective of this exploratory study was to investigate the overlooked perspectives and beliefs of Accredited Social Health Activists (ASHA workers) regarding a collaborative care mental health intervention (HOPE: Healthier Options through Empowerment), mental illness and the health of their rural communities.

DESIGN

Semi-structured, one-on-one, qualitative interviews.

SETTING

Seven primary health centres (PHCs) in rural Karnataka, India. All PHCs had previously completed the HOPE study.

PARTICIPANTS

15 ASHA workers, selected via purposive sampling. ASHAs are high school-educated village women trained as community health workers. ASHAs were included if they had previously participated in the HOPE intervention, a collaborative-care randomised controlled trial that aimed to integrate mental healthcare into existing primary care systems in rural Karnataka.

INTERVENTIONS

No interventions were introduced.

RESULTS

ASHA workers mostly had positive interactions with patients, including encouraging them to attend sessions, helping to explain the topics and techniques, and checking on the patients frequently. ASHA workers were able to identify key barriers to treatment and facilitators to treatment. ASHAs claimed that their knowledge about mental illness improved because of the HOPE study, though gaps remained in their understanding of aetiology and treatment. Several expressed interest in receiving additional mental health training. Overall, ASHAs viewed the HOPE study as a necessary and effective intervention, and requested that it expand.

CONCLUSIONS

This paper discusses the perspectives of ASHAs who participated in a novel effort to extend the collaborative care model to their own communities. ASHA workers help maintain relationships with patients that encourage participation, and the efforts of ASHAs often aid in mitigating common barriers to treatment. ASHA workers' beliefs and knowledge regarding mental illness can be changed, and ASHAs can become effective advocates for patients. Future collaborative care interventions would likely benefit from involving ASHA workers in community outreach efforts.

The Role of Noncommunicable Diseases in the Pursuit of Global Health Security

Noncommunicable diseases and their risk factors are important for all aspects of outbreak preparedness and response, affecting a range of factors including host susceptibility, pathogen virulence, and health system capacity. This conceptual analysis has 2 objectives. First, we use the Haddon matrix paradigm to formulate a framework for assessing the relevance of noncommunicable diseases to health security efforts throughout all phases of the disaster life cycle: before, during, and after an event. Second, we build upon this framework to identify 6 technical action areas in global health security programs that are opportune integration points for global health security and noncommunicable disease objectives: surveillance, workforce development, laboratory systems, immunization, risk communication, and sustainable financing. We discuss approaches to integration with the goal of maximizing the reach of global health security where infectious disease threats and chronic disease burdens overlap.

A road-map for addressing antimicrobial resistance in low- and middle-income countries: lessons learnt from the public private participation and co-designed antimicrobial stewardship programme in the State of Kerala, India

BACKGROUND

The global concern over antimicrobial resistance (AMR) is gathering pace. Low- and middle-income countries (LMICs) are at the epicentre of this growing public health threat and governmental and healthcare organizations are at different stages of implementing action plans to tackle AMR. The South Indian state of Kerala was one of the first in India to implement strategies and prioritize activities to address this public health threat.

STRATEGIES

Through a committed and collaborative effort from all healthcare related disciplines and its professional societies from both public and private sector, the Kerala Public Private Partnership (PPP) has been able to deliver a state-wide strategy to tackle AMR A multilevel strategic leadership model and a multilevel implementation approach that included developing state-wide antibiotic clinical guidelines, a revision of post-graduate and undergraduate medical curriculum, and a training program covering all general practitioners within the state the PPP proved to be a successful model for ensuring state-wide implementation of an AMR action plan. Collaborative work of multi-professional groups ensured co-design and development of disease based clinical treatment guidelines and state-wide infection prevention policy. Knowledge exchange though international and national platforms in the form of workshops for sharing of best practices is critical to success. Capacity building at both public and private institutions included addressing practical and local solutions to the barriers e.g. good antibiotic prescription practices from primary to tertiary care facility and infection prevention at all levels.

CONCLUSION

Through 7 years of stakeholder engagement, lobbying with government, and driving change through co-development and implementation, the PPP successfully delivered an antimicrobial stewardship plan across the state. The roadmap for the implementation of the Kerala PPP strategic AMR plan can provide learning for other states and countries aiming to implement action plans for AMR.

Leveraging role of non-physician health workers in prevention and control of non-communicable diseases in India: Enablers and challenges

Due to upsurge of non-communicable disease (NCD) burden, there is accentuated emphasis on task sharing and shifting NCDs-related health care delivery to non-physician healthcare workers especially nursing personnel and grass root level health professionals. This narrative review summates role of non-physician health workers, highlights various enablers and challenges while engaging them in delivery of NCD services so as to prevent and control various NCDs in India. Pubmed, Google scholar databases were searched using various keywords and Mesh terminologies. In addition, reference lists of selected articles were also screened. It is concluded that with regular update of knowledge, training, and supervision, these workers can efficiently deliver promotive, preventive, curative, and rehabilitative NCD-related healthcare services to needy. While engagement of this workforce in NCDs mitigation is a transforming concept, it also has its own challenges and issues which need to be explored and addressed in order to utilize this human resource to their maximum potential.

Epidemiology of Ischemic Heart Disease and Diabetes in South Asia: An Overview of the Twin Epidemic

BACKGROUND & OBJECTIVES

Ischemic heart disease (IHD) is one of the most important causes of death and disability in the world and diabetes is an important risk factor. This review was performed to describe the mortality and morbidity burden from this twin epidemic in South Asian countries.

METHODS

Country-level data on the epidemiology of IHD and diabetes were obtained from the Global Burden of Disease (GBD) study. Sub-national data were available only for India. We also retrieved epidemiological studies from published reviews on IHD and diabetes in India. These were supplemented with MEDLINE search.

RESULTS

GBD study and regional epidemiological studies have reported that there are significant regional variations in IHD mortality and disease burden within South Asian countries. IHD burden has increased significantly from 2000 to 2017. Prospective Urban Rural Epidemiology study has reported that diabetes is an important IHD risk factor in the South Asian region. GBD Study and International Diabetes Federation have reported increasing diabetes-related mortality and disease burden in South Asian countries, especially India. There are regional variations in diabetes-related mortality, disease burden, and prevalence in South Asia. At the macrolevel, rapid food and nutrition transition along with increasing physical inactivity is responsible for this twin epidemic.

CONCLUSION

Increasing trends in IHD and diabetes-related mortality and disease burden with regional variations are observed in South Asian countries.

A cross-sectional validation study comparing the accuracy of different risk scores in assessing the risk of acute coronary syndrome among patients in a tertiary care hospital in Kerala

Background

There are many cardiovascular disease (CVD) risk score calculators in practice, which are not based on Indian population data.

Objectives

To identify the best CVD risk score calculator applicable in the Indian population.

Materials and methods

A total of 1000 patients presenting with acute coronary syndrome (ACS) were included in the study and their CVD risk score, had they presented before the event, was calculated. The Framingham risk score (FRS–body mass index [BMI], FRS–fasting lipid profile [FLP]), the American College of Cardiology/American Heart Association pooled cohort equation risk calculator (ACC/AHA PCE), Joint British Society risk calculator 3 (JBS3) and the World Health Organization (WHO) risk prediction charts (WHO TC and WHO without TC [WHO NO TC]) were used.

Results

It was seen that among the 1000 people included in the study, the FRS-BMI (59.2%), FRS-FLP (61.5%), ACC/AHA (70.1%) and the JBS3 (62.5%) identified a majority as having a risk of ≥20%, whereas both the WHO TC (65.3%) and the WHO NO TC (64.5%) identified a majority of the ACS patients as having a risk of <20%. The sensitivity was highest for the ACC/AHA (87.8%), FRS-FLP (85.1%) and then JBS3 (80.1%), whereas the specificity was highest for the WHO TC (83.6%) and the WHO NO TC (82.1%). When looking at the accuracy, the FRS-FLP was the most accurate with 80.1%, whereas the ACC/AHA and the JBS3 followed at 74.7% and 73.1%, respectively.

Conclusion

The ACC/AHA seems to be an acceptable risk prediction system to be used in the Indian population and is also relatively easy and cheap to use.

A model for point of care testing for non-communicable disease diagnosis in resource-limited countries

Non-communicable disease diagnosis frequently relies on biochemical measurements but laboratory infrastructure in low-income settings is often insufficient and distances to clinics may be vast. We present a model for point of care (POC) epidemiology as used in our study of chronic disease in the Haiti Health Study, in rural and urban Haiti. Point of care testing (POCT) of creatinine, cholesterol, and hemoglobin A1c as well as physical measurements of weight, height, and waist circumference allowed for diagnosis of diabetes, chronic kidney disease, dyslipidemias, and obesity. Methods and troubleshooting techniques for the data collection of this study are presented. We discuss our method of community-health worker (CHW) training, community engagement, study design, and field data collection. We also discuss the machines used and our quality control across CHWs and across geographical regions. Pitfalls tended to include equipment malfunction, transportation issues, and cultural differences. May this paper provide information for those attempting to perform similar diagnostic and screening studies using POCT in resource poor settings.

Taking stock of 10 years of published research on the ASHA programme: examining India's national community health worker programme from a health systems perspective

BACKGROUND

As India's accredited social health activist (ASHA) community health worker (CHW) programme enters its second decade, we take stock of the research undertaken and whether it examines the health systems interfaces required to sustain the programme at scale.

METHODS

We systematically searched three databases for articles on ASHAs published between 2005 and 2016. Articles that met the inclusion criteria underwent analysis using an inductive CHW-health systems interface framework.

RESULTS

A total of 122 academic articles were identified (56 quantitative, 29 mixed methods, 28 qualitative, and 9 commentary or synthesis); 44 articles reported on special interventions and 78 on the routine ASHA program. Findings on special interventions were overwhelmingly positive, with few negative or mixed results. In contrast, 55% of articles on the routine ASHA programme showed mixed findings and 23% negative, with few indicating overall positive findings, reflecting broader system constraints. Over half the articles had a health system perspective, including almost all those on general ASHA work, but only a third of those with a health condition focus. The most extensively researched health systems topics were ASHA performance, training and capacity-building, with very little research done on programme financing and reporting, ASHA grievance redressal or peer communication. Research tended to be descriptive, with fewer influence, explanatory or exploratory articles, and no predictive or emancipatory studies. Indian institutions and authors led and partnered on most of the research, wrote all the critical commentaries, and published more studies with negative results.

CONCLUSION

Published work on ASHAs highlights a range of small-scale innovations, but also showcases the challenges faced by a programme at massive scale, situated in the broader health system. As the programme continues to evolve, critical comparative research that constructively feeds back into programme reforms is needed, particularly related to governance, intersectoral linkages, ASHA solidarity, and community capacity to provide support and oversight.

Role of Geographic Information System in Assessing Determinants of Cardiovascular Disease: An Experience From a Low- and Middle-Income Country

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the world. The determinants of CVD in an urban population using conventional and geographic information system techniques were attempted as a community-based census-type cross-sectional study in Kerala, India, among 1649 individuals residing in 452 households. Sociodemographic details, risk factor exposures, and self-reported disease prevalence were determined. Location of houses, wells from which subjects drew drinking water, and distances of the house from the outer road (proxy for air pollution) were mapped using differential global positioning system and pH of water samples determined. Prevalence of CVD was 5.8%. Significant predictors of CVD were male gender, diabetes mellitus, hypertension, and hypothyroidism. Statistically significant spatial association was found between CVD and groundwater pH. Geographic information system technology is useful in identification of spatial clustering and disease hotspots for designing preventive strategies targeting CVD.

Trends in Coronary Heart Disease Epidemiology in India

Cardiovascular diseases, especially coronary heart disease (CHD), are epidemic in India. The Registrar General of India reported that CHD led to 17% of total deaths and 26% of adult deaths in 2001-2003, which increased to 23% of total and 32% of adult deaths in 2010-2013. The World Health Organization (WHO) and Global Burden of Disease Study also have highlighted increasing trends in years of life lost (YLLs) and disability-adjusted life years (DALYs) from CHD in India. In India, studies have reported increasing CHD prevalence over the last 60 years, from 1% to 9%-10% in urban populations and <1% to 4%-6% in rural populations. Using more stringent criteria (clinical ± Q waves), the prevalence varies from 1%-2% in rural populations and 2%-4% in urban populations. This may be a more realistic prevalence of CHD in India. Case-control studies have reported that important risk factors for CHD in India are dyslipidemias, smoking, diabetes, hypertension, abdominal obesity, psychosocial stress, unhealthy diet, and physical inactivity. Suitable preventive strategies are required to combat this epidemic.

Assessment of 2013 AHA/ACC ASCVD risk scores with behavioral characteristics of an urban cohort in India: Preliminary analysis of Noncommunicable disease Initiatives and Research at AMrita (NIRAM) study

Cardiovascular diseases (CVDs) are the leading cause of death and disability in India. Early and sustained exposure to behavioral risk factors leads to development of CVDs.The aim of this study was to determine the baseline risk of a "hard CVD event" in subjects attending comprehensive health clinic and assess behavioral characteristics in "at risk" population.Using WHO STEPwise approach to Surveillance modified questionnaire, prevalence of noncommunicable diseases (NCDs) and risk factors was estimated in this cross-sectional study of 4507 subjects. Baseline cardiovascular risk was determined using Framingham risk score (FRS) and American College of Cardiology (ACC)/American Heart Association (AHA) atherosclerotic cardiovascular disease (ASCVD) algorithms. Modifiable behavior associated with high CVD risk was assessed. Among 40 to 59-year olds, ASCVD risk tool derived both a 10-year and lifetime risk score, which were used to stratify the cohort into 3 risk groups, namely, a high 10-year and high lifetime, a low 10-year and high lifetime, and a low 10-year and low lifetime risks.Dyslipidemia (30.6%), hypertension (25.5%), diabetes mellitus (20%), and obstructive airway disorders (17.6%) were most prevalent NCDs in our cohort. The ASCVD score stratified 26.1% subjects into high 10-yr and 59.5% into high lifetime risk while FRS classified 17.2% into high 10-year risk. Compared with FRS, the ASCVD risk estimator identified a larger proportion of subjects "at risk" of developing CVD. A high prevalence of alcohol use (38.4%), decreased intake of fruits and vegetables (96.2%) and low physical activity (58%) were observed in "at risk" population. Logistic regression analysis showed that in 40 to 59-year group, regular and occasional drinkers were 8.5- and 3.1-fold more likely to be in high 10-year and high lifetime ASCVD risk category than in low 10-year and low lifetime risk group. Similarly, regular drinkers and occasional drinkers were 2.1 and 1.3 times more likely to be in low 10-year and high lifetime risk than in low 10-year and low lifetime risk category. Subjects with inadequate intake of fruits and vegetables were 1.59 times more likely to be in low 10-year and high lifetime risk than the lower 10-year and lifetime risk group. Obese participants were 2.3-fold more likely to be in low 10-year and high lifetime risk.Identification of "at risk" subjects from seemingly healthy population will allow sustainable primary prevention strategies to reduce CVD.

Potential for mobile health (mHealth) prevention of cardiovascular diseases in Kerala: A population-based survey

BACKGROUND

India's southern state of Kerala stands at the forefront of India's epidemic of cardiovascular disease (CVD), among other non-communicable diseases (NCDs). Mobile phone use in healthcare (mHealth) has shown promise in India, including NCDs. However, suitability and acceptability of m-Health interventions is poorly researched, particularly in rural settings.

OBJECTIVES

METHODS: A questionnaire regarding mobile phone usage and possible use in healthcare was verbally administered in five primary health centres and by home visits in five village councils ("panchayats") of Ernakulam, Kerala. Adults who spoke Malayalam or English, with access to a mobile phone were recruited by convenience sampling in partnership with accredited social health activists (ASHAs). Quantitative data analysis was conducted using SPSS software.

RESULTS

262 participants were recruited. 87% routinely used and 88% owned a mobile phone. 92% were willing to receive mHealth advice, and 94% favoured mobile medication reminders. 70.3% and 73% preferred voice calls over short messaging service (SMS) for delivering health information and medication reminders, respectively. 85.9% would send home recorded information on their blood pressure, weight, medication use and lifestyle to a doctor or ASHA. 75.2% trusted the confidentiality of mHealth data, while 77.1% had no concerns about the privacy of their information.

CONCLUSIONS

The majority of this population approve mHealth interventions. While further investigation of mHealth as a health education tool is warranted, SMS interventions may fail to maximise equity and penetration across all patient groups.

The global pendulum swing towards community health workers in low- and middle-income countries: a scoping review of trends, geographical distribution and programmatic orientations, 2005 to 2014

BACKGROUND

There has been a substantial increase in publications and interest in community health workers (CHWs) in low- and middle-income countries (LMIC) over the last years. This paper examines the growth, geographical distribution and programmatic orientations of the indexed literature on CHWs in LMIC over a 10-year period.

METHODS

A scoping review of publications on CHWs from 2005 to 2014 was conducted. Using an inclusive list of terms, we searched seven databases (including MEDLINE, CINAHL, Cochrane) for all English-language publications on CHWs in LMIC. Two authors independently screened titles/abstracts, downloading full-text publications meeting inclusion criteria. These were coded in an Excel spreadsheet by year, type of publication (e.g. review, empirical), country, region, programmatic orientation (e.g. maternal-child health, HIV/AIDS, comprehensive) and CHW roles (e.g. prevention, treatment) and further analysed in Stata14. Drawing principally on the subset of review articles, specific roles within programme areas were identified and grouped.

FINDINGS

Six hundred seventy-eight publications from 46 countries on CHWs were inventoried over the 10-year period. There was a sevenfold increase in annual number of publications from 23 in 2005 to 156 in 2014. Half the publications were reporting on initiatives in Africa, a third from Asia and 11 % from the Americas (mostly Brazil). The largest single focus and driver of the growth in publications was on CHW roles in meeting the Millennium Development Goals of maternal, child and neonatal survival (35 % of total), followed by HIV/AIDS (16 %), reproductive health (6 %), non-communicable diseases (4 %) and mental health (4 %). Only 17 % of the publications approached CHW roles in an integrated fashion. There were also distinct regional (and sometimes country) profiles, reflecting different histories and programme traditions.

CONCLUSIONS

The growth in literature on CHWs provides empirical evidence of ever-increasing expectations for addressing health burdens through community-based action. This literature has a strong disease- or programme-specific orientation, raising important questions for the design and sustainable delivery of integrated national programmes.

Below the poverty line and non-communicable diseases in Kerala: The Epidemiology of Non-communicable Diseases in Rural Areas (ENDIRA) study

INTRODUCTION

India carries the greatest burden of global non-communicable diseases (NCDs). Poverty is strongly associated with NCDs but there are few prevalence studies which have measured poverty in India, particularly in rural settings.

METHODS

In Kerala, India, a population of 113,462 individuals was identified. The "Epidemiology of Non-communicable Diseases in Rural Areas" (ENDIRA) study was conducted via ASHAs (Accredited Social Health Activists). Standardised questionnaires were used in household interviews of individuals ≥18years during 2012 to gather sociodemographic, lifestyle and medical data for this population. The Government of Kerala definition of "the poverty line" was used. The association between below poverty line (BPL) status, NCDs and risk factors was analysed in multivariable regression models.

RESULTS

84,456 adults were included in the analyses (25.4% below the poverty line). The prevalence of NCDs was relatively common: myocardial infarction (MI) 1.4%, stroke 0.3%, respiratory diseases 5.0%, and cancer 1.1%. BPL status was not associated with age (p=0.96) or gender (p=0.26). Compared with those above the poverty line (APL), the BPL group was less likely to have diabetes, hypertension or dyslipidaemia (p<0.0001), and more likely to smoke (p<0.0001). Compared with APL, BPL was associated with stroke (OR 1.33, 1.04-1.69; p=0.02) and respiratory disease (OR 1.23, 1.15-1.32; p<0.0001) in multivariable analyses, but not MI or cancer.

CONCLUSIONS

In rural Kerala, BPL status was associated with stroke and respiratory diseases, but not with MI and cancer although it was associated with smoking status, compared with above poverty line status.
