Implementation Research on Cardiovascular Diseases in India: A Systematic Review.

SUMMARY: Cardiovascular diseases (CVDs) are the leading cause of death globally and the prevention and control of these diseases tend to entail longer and larger social and economic commitments on the part of governments. This systematic review (SR) aims to understand the quantum, diversity, and quality of implementation research (IR) done in the field of CVDs in India with a view to maximizing the utility of the efforts made by the government. The evidence was collated on IR on CVDs in India conducted in the past 20 years (2001-2021) using a SR approach. The SR was drafted using Preferred Reporting Items for SRs and Meta-analyses guidelines. Academic databases (PubMed, Embase, and Science Direct) and nonacademic databases (Google Scholar and ProQuest) were chosen, along with repositories of gray literature. Retrieved articles were screened for titles and abstracts and assessed by two independent reviewers. The articles also underwent a concomitant risk of bias assessment utilizing checklists (STARI, STROBE, CONSORT, etc.,) and a narrative summary was drafted using SwiM guidelines. In the final analysis, 10 articles that fitted the inclusion criteria of IR for CVD in India were included, of which seven were directed at IR on hypertension, and three were related to coronary artery disease, myocardial infarction, and stroke. Acceptability, adoption, and feasibility were the only attributes of IR that were explored in these studies.

Impact of Remedial Exercise Training on Work-Related Musculoskeletal Morbidity Among Handloom Weavers in Kanchipuram District: A Quasi-experimental Study.

INTRODUCTION: The handloom weaving industry is integral to developing countries, especially in South Asia, where traditional techniques are still widely practiced. In India, the handloom sector is a significant part of the informal economy, employing millions and preserving rich cultural heritage. Despite its economic and cultural importance, the sector faces severe challenges, including poor working conditions that lead to a high prevalence of work-related musculoskeletal disorders (WMSDs). This study focuses on assessing the prevalence of musculoskeletal morbidity and the effectiveness of physiotherapy interventions in reducing WMSDs among handloom weavers in Kanchipuram, Tamil Nadu. METHODS: This quasi-experimental study utilized a pre- and post-test design conducted over 12 months. A total of 121 handloom weavers from four major cooperative societies in Kanchipuram were selected using multistage sampling. Inclusion criteria were adults over 18 years, full-time weavers with more than a year of experience, and those who consented to participate. The study involved initial data collection through interviews using a pre-tested semi-structured questionnaire and the Standardized Nordic Musculoskeletal Questionnaire to assess pain prevalence. The intervention phase included physiotherapy exercise training thrice a week for three months, followed by post-intervention data collection and analysis. RESULTS: Pre-intervention data indicated high prevalence rates of musculoskeletal pain, with 62% of participants reporting knee pain and 54.5% reporting ankle/foot pain over the past year. Post-intervention assessments showed significant reductions in pain across all body parts, with the most substantial decreases in knee and shoulder pain. For instance, knee pain scores decreased from 3.10 ± 2.61 to 1.81 ± 1.69. The overall mean pain rating significantly dropped from 1.72 ± 0.88 pre-intervention to 1.00 ± 0.50 post-intervention, demonstrating the effectiveness of the physiotherapy exercises. CONCLUSION: The study confirms the high prevalence of musculoskeletal disorders (MSDs) among handloom weavers and demonstrates the significant impact of physiotherapy interventions in alleviating pain. Implementing regular physiotherapy exercises can substantially improve the well-being and productivity of handloom weavers, ensuring the sustainability of this vital cultural and economic industry. The results advocate for policy changes and increased support for ergonomic and health interventions in the handloom sector.

Return on investment of tobacco control measures: a systematic review protocol.

OBJECTIVE: The objective of this systematic review will be to estimate the return on investment (ROI) and social return on investment (SROI) on tobacco control measures. INTRODUCTION: Tobacco consumption has been proven to be associated with a huge epidemiological, humanistic, and economic burden. National and international organizations are making concerted efforts to control tobacco use. However, currently, there are no conclusive estimates of the ROI and SROI of such programs and policies. INCLUSION CRITERIA: This review will include all studies that evaluate the ROI or SROI on tobacco control programs and policies on tobacco users and probable tobacco users globally. METHODS: This review will follow the JBI methodology for systematic reviews of economic evidence. Databases to be searched will include Embase (Ovid), MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), Health Economic Evaluation Database (HEED), National Health Service Economic Evaluation Database (NHS EED), CEA Registry, LILACS, Science Direct, Web of Science, EconLit, and Google Advanced Search. Gray literature will also be searched for in non-academic databases, including the websites of various civil societies and non-governmental organizations involved in tobacco control. Two independent reviewers will screen titles/abstracts, and later full-text studies. Critical appraisal will be conducted using the JBI checklist for economic evaluations and the SROI Quality Framework. Data will be extracted and synthesized using JBI data extraction forms and synthesis tools. The MPOWER framework will be considered for data synthesis across all selected studies using narrative synthesis, tables, and figures. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42023391591.

Participatory research in mental health care services in low- and middle-income countries: a scoping review protocol.

OBJECTIVE: The objective of this scoping review will be to identify and map the characteristics of participatory research approaches in mental health care services conducted in low- and middle-income countries (LMICs). INTRODUCTION: Developing countries have a treatment gap of 76% to 85% for mental disorders. Participatory research can help understand community perspectives, which, in turn, helps develop sustainable, contextually specific services. Although participatory research appears promising, especially in the context of LMICs, the field is heterogenous in terms of the methods used; the various stakeholders; the design, implementation, and evaluation of services; and outcome measures. INCLUSION CRITERIA: This review will include all studies on participatory research in mental health care services in LMICs. All types of participants (ie, children/adolescent/adults, gender, rural/urban, etc.) and settings will be considered. METHODS: The proposed review will follow the JBI methodology for scoping reviews. Published and unpublished studies will be searched for in MEDLINE (PubMed), Embase (Ovid), PsycINFO (EBSCOhost), CINAHL (EBSCOhost), and Google Scholar (first 10 pages). We will also search for gray literature and screen reference lists of relevant reviews. Two independent reviewers will screen the titles and abstracts of the studies, followed by full-text screening. Data will be extracted using a predefined form. The findings will be descriptively presented with supporting tables and diagrams, accompanied by a narrative summary. REVIEW REGISTRATION: Details of the review can be found in Open Science Framework https://osf.io/cn54r.

Perception of human rights in health care: A cross-sectional study among tribal young adults of Puruliya, West Bengal.

Background: Human rights provide a universal foundation for pursuing justice in public health in order to achieve the dignity of all individuals. In spite of international attempts to promote human rights in the context of health, a significant portion of India's indigenous population continues to have a limited understanding of these rights. Objective: This study aims to analyze tribal people's attitudes towards human rights in health care. The population consists of tribal residents from Manbazar - I and Puncha Blocks in the Puruliya district of West Bengal, India. Tribal young adults between the ages of 18 and 35 were the subject of a cross-sectional study. Methods: A pretested questionnaire was used to collect data. MS Excel and SPSS 27 were used for analysis. A descriptive analysis was carried out. Results: The participants' mean scores for awareness, accessibility and communication, autonomy and sexual and reproductive health and sexual and reproductive health rights (SRHR) were 8.06, 15.76, 7.35 and 32.52 revealing a moderate perception level among the young adult tribal population in the selected blocks. Conclusion: A holistic focus of the governmental and other non-governmental organizations towards the tribals is required. Introducing various aspects of human rights in healthcare in the education curriculum along with community outreach would by all likelihood improve the perception of 'Human Rights' and thus help in better utilization of various services including health among tribal populations in India.

Improving medication adherence among persons with cardiovascular disease through m-health and community health worker-led interventions in Kerala; protocol for a type II effectiveness-implementation research-(SHRADDHA-ENDIRA).

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of mortality worldwide, and at present, India has the highest burden of acute coronary syndrome and ST-elevation myocardial infarction (MI). A key reason for poor outcomes is non-adherence to medication. METHODS: The intervention is a 2 × 2 factorial design trial applying two interventions individually and in combination with 1:1 allocation ratio: (i) ASHA-led medication adherence initiative comprising of home visits and (ii) m-health intervention using reminders and self-reporting of medication use. This design will lead to four potential experimental conditions: (i) ASHA-led intervention, (ii) m-health intervention, (iii) ASHA and m-health intervention combination, (iv) standard of care. The cluster randomized trial has been chosen as it randomizes communities instead of individuals, avoiding contamination between participants. Subcenters are a natural subset of the health system, and they will be considered as the cluster/unit. The factorial cluster randomized controlled trial (cRCT) will also incorporate a nested health economic evaluation to assess the cost-effectiveness and return on investment (ROI) of the interventions on medication adherence among patients with CVDs. The sample size has been calculated to be 393 individuals per arm with 4-5 subcenters in each arm. A process evaluation to understand the effect of the intervention in terms of acceptability, adoption (uptake), appropriateness, costs, feasibility, fidelity, penetration (integration of a practice within a specific setting), and sustainability will be done. DISCUSSION: The effect of different types of intervention alone and in combination will be assessed using a cluster randomized design involving 18 subcenter areas. The trial will explore local knowledge and perceptions and empower people by shifting the onus onto themselves for their medication adherence. The proposal is aligned to the WHO-NCD aims of improving the availability of the affordable basic technologies and essential medicines, training the health workforce and strengthening the capacity of at the primary care level, to address the control of NCDs. The proposal also helps expand the use of digital technologies to increase health service access and efficacy for NCD treatment and may help reduce cost of treatment. TRIAL REGISTRATION: The trial has been registered with the Clinical Trial Registry of India (CTRI), reference number CTRI/2023/10/059095.

Economic burden and economic impact associated with non-communicable diseases among countries of World Health Organization South-East Asia Region - a systematic review protocol.

OBJECTIVE: The objective of this systematic review is to synthesize studies on economic burden and economic impact of noncommunicable diseases (NCDs) in the World Health Organization South-East Asian Region (WHO SEAR) countries. INTRODUCTION: WHO SEAR countries represent 8.6% of the world's population and 75% of all deaths in this region are attributable to NCDs. In addition, there is a pattern of low government spending on health in SEAR countries, leading to a high proportion of health financing by patients', risking impoverishment for households. INCLUSION CRITERIA: We will consider observational (cross-sectional, cohort, and case-control) and interventional (either single arm or comparative) studies that report economic burden (direct and indirect costs, out-of-pocket expenditure) and economic impact (catastrophic health expenditure, hardship financing, impoverishment, and gross domestic product impact at individual, household, and/or country levels). This includes government surveys, surveillance, and secondary data analyses for one or more NCDs prevalent in the WHO SEAR. METHODS: We will conduct a comprehensive search for relevant studies in databases, including PubMed (MEDLINE), Embase (Ovid), Scopus, Web of Science, Google Scholar, and gray literature with no date limits. Two independent reviewers will screen titles and abstracts, followed by full-text screening. Included studies will be critically appraised for quality. Data will be extracted accordingly and, if possible, random effects meta-analyses will be conducted on the pooled data for resource utilization and costs (including burden and impact), presenting the degree of variation between studies. The characteristics and results of the included studies will be narratively summarized with accompanying tables. REVIEW REGISTRATION: PROSPERO CRD42023421302.

Cost and cost-effectiveness of treatments for rheumatic heart disease in low- and middle-income countries: a systematic review protocol.

OBJECTIVE: This review will synthesize studies on costs, the impact of these costs, and the cost-effectiveness of treatments for rheumatic heart disease (RHD) in low- and middle-income countries. INTRODUCTION: RHD incurs high costs owing to its clinical complexity, surgical treatments, and prolonged hospital stays. Thus, the disease has a substantial economic impact on the health system, patients, and their families. No systematic review on economic evidence of treatments for RHD has been published to date. INCLUSION CRITERIA: This review will consider all cost and cost-effectiveness studies on RHD treatments for children and young adults (5─30 years) residing in low- and middle-income countries. METHODS: The review will follow the JBI methodology for systematic reviews of economic evaluation evidence. The search strategy will locate published and unpublished studies in English. Systematic searches will be conducted in MEDLINE (PubMed), MEDLINE (Ovid), Embase (Ovid), Scopus, CINAHL (EBSCOhost), National Health Service Economic Evaluation Databases, Pediatric Economic Database Evaluation, and Cost-Effectiveness Analysis Registry. Two independent reviewers will screen titles and abstracts, followed by a full-text review based on the inclusion criteria. Data will be extracted using a modified JBI data extraction form for economic evaluations. JBI's Dominance Ranking Matrix for economic evaluations will be used to summarize and compare the results of cost and cost-effectiveness studies. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach will be used to assess the certainty of economic evidence for outcomes related to resource use. REVIEW REGISTRATION: PROSPERO CRD42023425850.

Political economy analysis of health: a scoping review protocol.

OBJECTIVE: The objective of this scoping review is to identify and map the literature on concepts, definitions, frameworks, outcomes, and applications of political economic analysis of health. INTRODUCTION: The political economy of health approach seeks to understand how political and economic domains interact and shape individual and population health outcomes. A political economic analysis can provide insights into health problems and inequalities; however, there needs to be more clarity on how the political economy framework is defined and the methods adopted for conducting political economy analysis concerning health. INCLUSION CRITERIA: Studies focusing on the political economy analysis addressing specific health problems will be included. The study population is not limited to any sociodemographic characteristics, and there will be no restrictions on language or the source of evidence (primary studies or secondary data studies). Both qualitative and quantitative methodologies will included, but narrative and systematic reviews will be excluded, as will conference abstracts and editorials. Studies involving sector- or country-level analysis will be included. METHODS: The review will follow the JBI methodology for scoping reviews. Databases to be searched include MEDLINE, Scopus, Web of Science, Cochrane CENTRAL, CINAHL, Embase, ProQuest, DynaMed, and gray literature via Google Scholar and OAIster. Two reviewers will perform study screening and data extraction using a customized data extraction form. The concepts, definitions, frameworks, outcomes, and applications of the political economy of health will be summarized and discussed. The health problems addressed using political economy analysis will be enumerated. Stakeholder engagement will guide all steps of the study. Results will be presented in tabular and graphical formats accompanied by a narrative summary. REVIEW REGISTRATION: Open Science Framework https://osf.io/4qaxr/.

Morbidity among the tribal populations of West Bengal: A study based on data collected from the Mobile Medical Clinic.

Background: Tribes are the most socially excluded group in the nation due to their restricted access to healthcare. There are little data on the real burden and distribution of illnesses among tribes. The present study determines the types and patterns of sickness among tribal populations in West Bengal. Methods: Five blocks from five districts in West Bengal were used for this cross-sectional study. Between the years 2018 and 2019, 52,189 patients visited these mobile medical clinics (MMCs), but only 36,128 were included in our study. Data were analyzed using the SPSS software (ver. 27.0). Results: Younger age groups (1-25 years) show higher primary registration compared to other age categories; older age groups (>60 years) show higher repeat registration. High prevalence in infectious diseases (44.5% of the total primary registration) and high repeated cases in NCDs (11.5% to 33.2%), which are nearly three times higher than primary cases (Cramer's V test = 0.29; P = .001) are observed. Among the studied MMCs, Binpur II and Matiali MMC have more than two times the risk of gastrointestinal problems, while Madarihat MMC has more than one time the risk. Garbeta II MMC shows more than three times the risk of NCDs (adjusted odds ratio = 3.97; 95% confidence interval: 3.05-5.17) than the other diseases. Conclusion: The present study shows high prevalence of infectious diseases, injury and pain, NCDs, gastrointestinal problems, and vertigo in tribal populations of West Bengal.

Effectiveness of interpersonal psychotherapy in comparison to other psychological and pharmacological interventions for reducing depressive symptoms in women diagnosed with postpartum depression in low- and middle-income countries: A systematic review.

Background: Postpartum depression (PPD) is a condition that can affect any woman regardless of ethnicity, age, party, marital status, income, and type of delivery. This condition is highly prevalent worldwide. PPD, if not treated timely, can affect the maternal-child bond and can have a detrimental impact on the future cognitive, emotional, and behavioral development of the child. Interpersonal psychotherapy (IPT) has been reported as an effective treatment of PPD in previous studies as this focuses on relationship and social support issues. Previous reviews conducted in developed nations have reported the superior efficacy of IPT in comparison to other treatment options. There is no systematic review conducted in low to middle-income countries on the efficacy of IPT on PPD. Therefore it was necessary to undertake a systematic review to assess the effectiveness of IPT in reducing the depression among postpartum women in low and middle-income countries (LMICs). Objectives: The main aim of this systematic review was to assess the effectiveness of IPT alone or in conjunction with pharmacological therapy and/or other psychological and psychosocial interventions, in reducing depressive symptoms among women diagnosed with PPD residing in LMICs. Search Methods: The systematic search encompassed several prominent databases and grey literature. Furthermore, experts specializing in the field of IPT were consulted to identify any relevant studies conducted in LMICs that fulfilled the predetermined eligibility criteria. The most recent search update was performed in July 2022. Selection Criteria: The PICOS criteria were meticulously defined for this review as described. Participants: Postpartum women diagnosed with PPD in LMICs were included. Intervention: IPT either as a standalone treatment or in conjunction with pharmacological therapy was included. Comparison: any form of psychological therapy or pharmacological therapy, whether administered individually or in combination, was considered for comparison. Study designs: experimental and quasi-experimental, factorial designs, and quantitative components (experimental, quasi-experimental, factorial designs) of mixed methods designs were eligible to be included. Studies with single-group study designs and qualitative studies were excluded from the review. Data Collection and Analysis: Two reviewers from our team conducted a rigorous screening process to determine the eligibility of articles for inclusion. This involved an initial evaluation of titles and abstracts, followed by a comprehensive assessment of the full text of selected articles. In instances where discrepancies arose between the two reviewers, resolution was achieved through discussion or consultation with a third author to establish a consensus. Following the screening process, two team members independently extracted pertinent information and data from the studies that met the inclusion criteria. The treatment effect of the intervention, in comparison to the control group, was subsequently analyzed utilizing the fixed effects model taking into account the small number of studies. Main Results: A total of 17,588 studies were identified from various databases, and 6493 duplicate studies were removed. Subsequently, 9380 studies underwent independent title and abstract screening resulting in the exclusion of 9040 studies. 345 full texts were thoroughly assessed leading to the exclusion of 341 studies, finally including 4 studies for review. The four included trials were randomized trials and comprised a total sample size of 188 women diagnosed with PPD residing in LMICs. Among these studies, three compared IPT with usual treatment, while one study compared IPT with antidepressant medications (ADMs). In terms of the providers of IPT, in one study, IPT was administered by nurses, while psychologists delivered IPT in another study. In one study, community health workers were responsible for providing IPT. However, in one study, information regarding the specific providers of IPT was not available or reported. The primary outcome measure reported in all four studies was depression, assessed using the Edinburgh Postnatal Depression Scale (EPDS). The geographical distribution of the studies included; one conducted in Zambia, one in Kenya, one in Pakistan, and one in Iran. Out of the four studies, three were included in the meta-analysis, as missing data from one study could not be obtained. Based on the overall treatment effect, it was found that depression scores decreased significantly more in the IPT group compared to other interventions (usual treatment or ADMs) (standardized mean difference [SMD] -0.62, 95% confidence interval [CI] (-1.01, -0.23), Z = 3.13 (p = 0.002), χ 2 = 49.49; df = 2; p < 0.00001; I 2 = 96%; 3 studies, n = 136). Out of the three studies, two studies compared the effectiveness of IPT in reducing depression scores specifically when compared to the usual treatment, and in both studies, depression scores were reduced significantly in the IPT group as compared to the usual treatment group. Only one study directly compared the effectiveness of IPT with ADM, reporting that IPT was more effective than ADM in reducing depression scores among postpartum women. Regarding adverse outcomes, only one study reported suicidal ideation with one participant in the IPT group and two in the ADM group (RR 0.50, 95% CI (0.05, 5.30), p = 0.56, n = 78). The same study reported seven participants in the ADM group had adverse drug reactions as compared to none in the IPT group (RR 15.0, 95% CI (0.89, 254), p = 0.06, n = 78). Authors' Conclusions: Our comprehensive search yielded a limited number of four studies conducted in such settings. Despite the scarcity of available evidence, the findings collectively suggest that IPT is indeed an effective treatment for reducing PPD when compared to usual treatment and pharmacological therapy. However given the low certainty of evidence, there is a need for further research in the form of well-designed randomized controlled trials with larger sample sizes and a reduced risk of bias. Such studies would greatly contribute to enhancing the strength and reliability of the evidence base regarding the effectiveness of IPT in the context of PPD in LMICs. The knowledge generated from future research endeavors would be highly valuable in guiding the development of more affordable and cost-effective treatment approaches for PPD in resource-limited settings.

Hospitalisation expenditure on tuberculosis among tribal populations in India: A repeated cross-sectional analysis of national sample survey data, 2004 to 2018.

Objective: Tribal population in India (8.6% of the total population) have a greater prevalence of tuberculosis compared to the national average. The article aims to study out-of-pocket expenditure (OOPE), hardship financing, and impoverishment effects of TB hospitalisation treatment among tribal populations in India. Methods: Data of three rounds of National Sample Surveys (NSS) 60th (2004-05), 71st (2013-14) and 75th (2017-18) rounds were analyzed. Descriptive statistics, bivariate estimates and multivariate models were performed to calculate the OOPE, healthcare burden (HCB), catastrophic health expenditure (CHE), hardship financing and impoverishment effects using standard definitions at February 2023 price values. Propensity score matching (PSM) was used to examine the effect of health insurance coverage on catastrophic health expenditure, and impoverishment. Results: Over two-thirds of the TB cases are seen in the economically productive age group (14-59 years). Substantial OOPE and its impact on HCB, CHE, and poverty impact observed among 15-35 age group across all three rounds. Illiterate patients and those availing private hospitals for TB treatment had higher OOPE, HCB, hardship financing, CHE, and poverty impact. 38.5% (2014) and 33.2% (2018) are covered with any kind of public healthcare coverage, PSM analysis shows households with health insurance have lower incidence of CHE and impoverishment effects due to TB hospitalisation expenditure. Conclusions: The current study aids in comprehending the patterns in the financial burden of TB on tribal households during the previous 15 years and gives policy makers information for efficient resource allocation management for TB among Indian tribal communities.

Economic evaluations of neglected tropical disease interventions in low- and middle-income countries: a systematic review protocol.

OBJECTIVE: The objective of this systematic review is to provide an overview of economic evaluation studies of interventions for neglected tropical diseases in low- and/or middle-income countries. INTRODUCTION: The majority of people most susceptible to neglected tropical diseases reside in low- and middle-income countries and suffer significant economic impact due to these diseases. The World Health Organization suggests utilizing a systematic and cross-cutting approach with multiple interventions to lessen the neglected tropical disease burden. INCLUSION CRITERIA: Studies will be eligible for inclusion if they include economic evaluations of interventions for neglected tropical diseases and are conducted in low- and/or middle-income country settings. METHODS: A preliminary search of MEDLINE (PubMed) was undertaken using MeSH terms, such as neglected tropical disease, economic evaluation, therapeutics, low- and/or middle-income countries . Two reviewers will screen titles and abstracts independently, followed by a full-text review against the inclusion criteria. Disagreements will be resolved by discussion or with a third reviewer. To assess methodological quality, the JBI checklist for economic evaluations will be used. For economic evaluations, data will be extracted using the standardized JBI data extraction form. The Dominance Ranking Matrix will be used to summarize and compare the results of different types of economic evaluations. Cost per quality adjusted life year gained and cost per disability adjusted life year averted will be measures for economic evaluation. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach will be used to assess the certainty of economic evidence, such as resource use and costs. REVIEW REGISTRATION: PROSPERO CRD42017070386.

Cost-effectiveness of newborn screening for sickle cell disease: a systematic review protocol.

OBJECTIVE: The purpose of this systematic review is to assess the cost-effectiveness of targeted/selective newborn screening compared with universal screening for sickle cell disease across various countries and settings. INTRODUCTION: The incidence of sickle cell disease is a widespread and potentially fatal hematologic disorder that affects thousands of newborns worldwide. The cost of newborn screening creates a burden on households and the economy. INCLUSION CRITERIA: Studies will be eligible for inclusion in the review if they focus on the cost-effectiveness of newborn screening for sickle cell disease, comparing targeted/selective screening with universal screening. METHODS: A preliminary search of MEDLINE (PubMed) was undertaken using MeSH terms, such as sickle cell disease, newborn , and economic evaluations . Two reviewers will screen the titles, abstracts, and full text independently against the inclusion criteria. Disagreements will be resolved by discussion or with a third reviewer. To assess methodological quality, the JBI checklist for economic evaluation will be used. Data will be extracted by 2 reviewers using a modified JBI data extraction form. The JBI dominance ranking matrix for economic evaluations will be used to summarize and compare the results. Cost-effectiveness will be measured on the basis of cost per test/case detected, quality-adjusted life years gained, or disability-adjusted life years averted. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) assessment will be conducted to evaluate the certainty of economic evidence, such as use of resources and expenditures, and to incorporate the results into the decision-making process.

Effectiveness of road safety interventions: An evidence and gap map.

Background: Road Traffic injuries (RTI) are among the top ten leading causes of death in the world resulting in 1.35 million deaths every year, about 93% of which occur in low- and middle-income countries (LMICs). Despite several global resolutions to reduce traffic injuries, they have continued to grow in many countries. Many high-income countries have successfully reduced RTI by using a public health approach and implementing evidence-based interventions. As many LMICs develop their highway infrastructure, adopting a similar scientific approach towards road safety is crucial. The evidence also needs to be evaluated to assess external validity because measures that have worked in high-income countries may not translate equally well to other contexts. An evidence gap map for RTI is the first step towards understanding what evidence is available, from where, and the key gaps in knowledge. Objectives: The objective of this evidence gap map (EGM) is to identify existing evidence from all effectiveness studies and systematic reviews related to road safety interventions. In addition, the EGM identifies gaps in evidence where new primary studies and systematic reviews could add value. This will help direct future research and discussions based on systematic evidence towards the approaches and interventions which are most effective in the road safety sector. This could enable the generation of evidence for informing policy at global, regional or national levels. Search Methods: The EGM includes systematic reviews and impact evaluations assessing the effect of interventions for RTI reported in academic databases, organization websites, and grey literature sources. The studies were searched up to December 2019. Selection Criteria: The interventions were divided into five broad categories: (a) human factors (e.g., enforcement or road user education), (b) road design, infrastructure and traffic control, (c) legal and institutional framework, (d) post-crash pre-hospital care, and (e) vehicle factors (except car design for occupant protection) and protective devices. Included studies reported two primary outcomes: fatal crashes and non-fatal injury crashes; and four intermediate outcomes: change in use of seat belts, change in use of helmets, change in speed, and change in alcohol/drug use. Studies were excluded if they did not report injury or fatality as one of the outcomes. Data Collection and Analysis: The EGM is presented in the form of a matrix with two primary dimensions: interventions (rows) and outcomes (columns). Additional dimensions are country income groups, region, quality level for systematic reviews, type of study design used (e.g., case-control), type of road user studied (e.g., pedestrian, cyclists), age groups, and road type. The EGM is available online where the matrix of interventions and outcomes can be filtered by one or more dimensions. The webpage includes a bibliography of the selected studies and titles and abstracts available for preview. Quality appraisal for systematic reviews was conducted using a critical appraisal tool for systematic reviews, AMSTAR 2. Main Results: The EGM identified 1859 studies of which 322 were systematic reviews, 7 were protocol studies and 1530 were impact evaluations. Some studies included more than one intervention, outcome, study method, or study region. The studies were distributed among intervention categories as: human factors (n = 771), road design, infrastructure and traffic control (n = 661), legal and institutional framework (n = 424), post-crash pre-hospital care (n = 118) and vehicle factors and protective devices (n = 111). Fatal crashes as outcomes were reported in 1414 records and non-fatal injury crashes in 1252 records. Among the four intermediate outcomes, speed was most commonly reported (n = 298) followed by alcohol (n = 206), use of seatbelts (n = 167), and use of helmets (n = 66). Ninety-six percent of the studies were reported from high-income countries (HIC), 4.5% from upper-middle-income countries, and only 1.4% from lower-middle and low-income countries. There were 25 systematic reviews of high quality, 4 of moderate quality, and 293 of low quality. Authors' Conclusions: The EGM shows that the distribution of available road safety evidence is skewed across the world. A vast majority of the literature is from HICs. In contrast, only a small fraction of the literature reports on the many LMICs that are fast expanding their road infrastructure, experiencing rapid changes in traffic patterns, and witnessing growth in road injuries. This bias in literature explains why many interventions that are of high importance in the context of LMICs remain poorly studied. Besides, many interventions that have been tested only in HICs may not work equally effectively in LMICs. Another important finding was that a large majority of systematic reviews are of low quality. The scarcity of evidence on many important interventions and lack of good quality evidence-synthesis have significant implications for future road safety research and practice in LMICs. The EGM presented here will help identify priority areas for researchers, while directing practitioners and policy makers towards proven interventions.

Cost-effectiveness of a decentralized care model for managing multi-drug-resistant tuberculosis in low- and middle-income countries: a systematic review protocol.

OBJECTIVE: The purpose of this systematic review is to assess the available economic evidence of a decentralized care model compared to a centralized model for treating multi-drug-resistant tuberculosis (MDR-TB) in low- and middle-income countries (LMICs). INTRODUCTION: Diseases that affect physiological health create a burden on human livelihoods and the economy. There is a lack of studies examining the economic evaluation of MDR-TB across different countries. A preliminary search identified no published or ongoing reviews on MDR-TB in LMICs. INCLUSION CRITERIA: Studies will be eligible if they include both patients receiving centralized care (ie, care provided by specialist centers through inpatient or outpatient services) and patients receiving decentralized care (ie, care provided by grassroots community workers in peripheral facilities or in the patients' residence) for MDR-TB in LMICs. Eligible studies will report economic evaluations of treatment for MDR-TB. METHODS: A preliminary search of MEDLINE (PubMed) was undertaken using MeSH terms, such as MDR-TB, economic evaluation, therapeutics, LMICs . Two reviewers will independently screen the titles, abstracts, and full text against the inclusion criteria. Disagreements will be resolved through discussion or with a third reviewer. The JBI checklist for economic evaluations will be utilized to evaluate the methodological quality. Data will be extracted using a modified JBI data extraction form for economic evaluations. The Dominance Ranking Matrix, developed by JBI for economic evaluations, will be used to summarize and compare the results of different types of economic evaluations (cost-effectiveness, cost-benefit analysis, cost-utility analysis, or cost-minimization analysis). Cost per quality-adjusted life year gained and cost per disability-adjusted life year averted will be measures for economic evaluation. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach will be used to assess the certainty of economic evidence. REVIEW REGISTRATION: PROSPERO CRD42022368696.

Economic Burden of Mosquito-Borne Diseases in Low- and Middle-Income Countries: Protocol for a Systematic Review.

BACKGROUND: Globally, among all the vector-borne diseases, mosquito-borne diseases are responsible for a substantial number of cases and deaths and amount to an economic cost of US $12 billion per year. However, there is a dearth of systematic research conducted on the economic burden of mosquito-borne diseases. To address the lack of comprehensive information on this topic, a systematic review will be conducted to synthesize evidence for informing targeted policies and strategies addressing this growing burden and for better financial protection of households. OBJECTIVE: The systematic review aims to review the economic burden of mosquito-borne diseases in low- and middle-income countries (LMICs). The review estimates the total cost, which is the compilation of both the direct costs and indirect costs. Additionally, it reports cost estimates per disease, country, and patient. The review outcome will also discuss the impact of the economic burden in terms of out-of-pocket expenditure, catastrophic health expenditure, impoverishment, and gross domestic product impact due to mosquito-borne diseases in LMICs. METHODS: Systematic searches will be conducted in PubMed (MEDLINE), Ovid Embase, Scopus, the cumulative index of nursing and allied health literacy, and Cochrane CENTRAL. Additionally, websites of the World Bank, World Health Organization, and Asian Development Bank as well as grey literature (eg, Malaria No More and the Ministry of Health websites) will be searched to gather comprehensive information on the topic and identify studies published in the English language. The titles and abstracts will be independently screened by 2 reviewers, followed by a full-text review against the inclusion criteria. Disagreements will be resolved through discussion with a third author. The methodological reporting quality of the studies will be evaluated using the Larg and Moss checklist, Cochrane risk-of-bias tool for randomized trials, and the Consensus on Health Economic Criteria. Data will be extracted using a standardized data extraction form. RESULTS: The protocol was registered in PROSPERO (CRD42023427111) prior to the initiation of the search strategy. The review is currently ongoing and will synthesize information from the identified studies through a process involving structured screening, data extraction, and critical appraisal in the form of tables and a narrative summary of studies reporting the economic burden incurred due to mosquito-borne diseases in LMICs. CONCLUSIONS: This review seeks to report the economic burden of mosquito-borne diseases. It will act as evidence for policymakers to prioritize their decisions regarding containing the prevalence of mosquito-borne diseases and the means to lowering the incidence of diseases spread by mosquitoes.

Estimation of non-health gross domestic product (NHGDP) loss due to COVID-19 deaths in West Bengal, India.

OBJECTIVES: The state of West Bengal witnessed a significant surge of COVID-19 in all three waves. However, there is a gap in understanding the economic loss associated with COVID-19. This study estimates future non-health gross domestic product (NHGDP) losses associated with COVID-19 deaths in West Bengal, India. SETTING: Various open domains were used to gather data on COVID-19 deaths in West Bengal and the aforementioned estimates. PRIMARY AND SECONDARY OUTCOME MEASURES: The NHGDP losses were evaluated using the cost-of-illness approach. Future NHGDP losses were discounted at 3%. Excess death estimates by the WHO and Global Burden of Disease (GBD) were used. Sensitivity analysis was carried out by varying discount rates and average age of death (AAD). RESULTS: 21 532 deaths in West Bengal from 17 March 2020 to 31 December 2022 decreased the future NHGDP by $0.92 billion. Nearly 90% of loss was due to deaths occurring in the age group of 30 years and above. Majority of the NHGDP loss was borne by the 46-60 years age group. NHGDP loss/death was $55,171; however, the average loss/death declined with rise in age. Based on the GBD and WHO excess death estimates, the NHGDP loss increased to $9.38 billion and $9.42 billion, respectively. When the lower age interval is considered as AAD, the NHGDP loss increased to $1.3 billion. At 5% and 10% discount rates, the losses reduced to $0.767 billion and $0.549 billion, respectively. CONCLUSIONS: Results from the study suggest that COVID-19 contributed to a major economic loss in West Bengal. The mortality and morbidity caused by COVID-19, the substantial economic costs at individual and population levels in West Bengal, and probably across India and other countries, is another economic argument for better infection control strategies across the globe to minimise the impact of COVID-19.
