Disparities in Cardiovascular Research Output and Disease Outcomes among High-, Middle- and Low-Income Countries - An Analysis of Global Cardiovascular Publications over the Last Decade (2008-2017).

ABSTRACT:

Background

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. Health research is crucial to managing disease burden. Previous work has highlighted marked discrepancies in research output and disease burden between high-income countries (HICs) and low- and lower-middle-income countries (LI-LMICs) and there is little data to understand whether this gap has bridged in recent years. We conducted a global, country level bibliometric analysis of CVD publications with respect to trends in disease burden and county development indicators.

Methods

A search filter with a precision and recall of 0.92 and 0.91 respectively was developed to extract cardiovascular publications from the Web of Science (WOS) for the years 2008-2017. Data for disease burden and country development indicators were extracted from the Global Burden of Disease and the World Bank database respectively.

Results

Our search revealed 847,708 CVD publications for the period 2008-17, with a 43.4% increase over the decade. HICs contributed 81.1% of the global CVD research output and accounted for 8.1% and 8.5% of global CVD DALY losses deaths respectively. LI-LMICs contributed 2.8% of the total output and accounted for 59.5% and 57.1% global CVD DALY losses and death rates.

Conclusions

A glaring disparity in research output and disease burden persists. While LI-LMICs contribute to the majority of DALYs and mortality from CVD globally, their contribution to research output remains the lowest. These data call on national health budgets and international funding support to allocate funds to strengthen research capacity and translational research to impact CVD burden in LI-LMICs.

Project description:ObjectiveAlthough medication abortion has become more common in high-income countries, the procedure has not yet met early expectations for widening access to abortion. High-quality evidence can serve as a catalyst for changes in policy and practice. To direct research priorities, it is important to understand where quality evidence is concentrated and where gaps remain. High-income countries have developed a body of evidence that may have implications for the future of medication abortion. This literature review assesses the characteristics and quality of published studies on medication abortion conducted in the last 10 years in high-income countries and indicates future areas for research to advance policy and practice, and broaden access.Study designA structured search for literature resulted in 207 included studies. A framework based upon the World Health Organization definition of sub-tasks for medication abortion was developed to categorize research by recognized stages of the medication abortion process. Using an iterative and inductive approach, additional sub-themes were created under each of these categories. Established quality assessment frameworks were drawn upon to gauge the internal and external validity of the included research.ResultsStudies in the US and the UK have dominated research on MA in high-income countries. The political and social contexts of these countries will have shaped of this body of research. The past decade of research has focused largely on clinical aspects of medication abortion.ConclusionResearchers should consider refocusing energies toward testing service delivery approaches demonstrating promise and prioritizing research that has broader generalizability and relevance outside of narrow clinical contexts. Although medication abortion is more commonly available worldwide, it is not being used as often as people thought it would be, particularly in high income countries. In order to encourage changes in policy and practice that would allow greater use, we need good quality evidence. If we can understand where we do not have enough research and where we have good amounts of research, we can determine where to invest energies in further studies. Many high-income countries have produced research on medication abortion that could influence policy and practice in similarly resourced contexts. I conducted a literature review to be able to understand the type and quality of research on medication abortion conducted in high-income countries in the past 10 years. I conducted the review in an organized way to make sure that the papers reviewed discussed studies that I thought would be important for answering this question. The literature review found 207 papers. Each of these papers were reviewed and organized them by theme. I also used existing methods to determinine the quality of each study. Most of the research came from the US and the UK. Furthermore, most of the research conducted in the past 10 years was focused on clinical studies of medication abortion. In future studies, researchers should focus more on new ways of providing medication abortion to women that offers greater access. Also, the studies should be designed so that the results have meaning for a broader group of people or situations beyond where the study was done.

Project description:ImportanceScientific publication is an important tool for knowledge dissemination and career advancement, but authors affiliated with institutions in low- and middle-income countries (LMICs) are historically underrepresented on publications.ObjectiveTo assess the country income level distribution of author affiliations for publications resulting from National Cancer Institute (NCI)-supported extramural grants between 2015 and 2019, with international collaborating institutions exclusively in 1 or more LMICs.Design and settingThis cross-sectional study assessed authorship on publications resulting from NCI-funded grants between October 1, 2015, and September 30, 2019. Grants with collaborators in LMICs were identified in the National Institutes of Health (NIH) Query/View/Report and linked to publications using Dimensions for NIH, published between 2011 and 2020. Statistical analysis was performed from May 2021 to July 2022.Main outcomes and measuresAuthor institutional affiliation was used to classify author country and related income level as defined by the World Bank. Relative citation ratio and Altmetric data from Dimensions for NIH were used to compare citation impact measures using the Wilcoxon rank sum test.ResultsIn this cross-sectional study, 159 grants were awarded to US institutions with collaborators in LMICs, and 5 grants were awarded directly to foreign institutions. These 164 grants resulted in 2428 publications, of which 1242 (51%) did not include any authors affiliated with an institution in an LMIC. In addition, 1884 (78%) and 2009 (83%) publications had a first or last author, respectively, affiliated with a high-income country (HIC). Publications with HIC-affiliated last authors also demonstrated greater citation impact compared with publications with LMIC-affiliated last authors as measured by relative citation ratios and Altmetric Attention Scores; publications with HIC-affiliated first authors also had higher Altmetric Attention Scores.Conclusions and relevanceThis cross-sectional study suggests that LMIC-affiliated authors were underrepresented on publications resulting from NCI-funded grants involving LMICs. It is critical to promote equitable scientific participation by LMIC institutions in cancer research, including through current and planned programs led by the NCI.

Project description:IntroductionThe objective of this research is to provide national estimates of the prevalence of health condition diagnoses among age-entitled transgender and cisgender Medicare beneficiaries. Quantification of the health burden across sex assigned at birth and gender can inform prevention, research, and allocation of funding for modifiable risk factors.MethodsUsing 2009-2017 Medicare fee-for-service data, we implemented an algorithm that leverages diagnosis, procedure, and pharmacy claims to identify age-entitled transgender Medicare beneficiaries and stratify the sample by inferred gender: trans feminine and nonbinary (TFN), trans masculine and nonbinary (TMN), and unclassified. We selected a 5% random sample of cisgender individuals for comparison. We descriptively analyzed (means and frequencies) demographic characteristics (age, race/ethnicity, US census region, months of enrollment) and used chi-square and t-tests to determine between- (transgender vs. cisgender) and within-group gender differences (e.g., TMN, TFN, unclassified) difference in demographics (p<0.05). We then used logistic regression to estimate and examine within- and between-group gender differences in the predicted probability of 25 health conditions, controlling for age, race/ethnicity, enrollment length, and census region.ResultsThe analytic sample included 9,975 transgender (TFN n=4,198; TMN n=2,762; unclassified n=3,015) and 2,961,636 cisgender (male n=1,294,690, female n=1,666,946) beneficiaries. The majority of the transgender and cisgender samples were between the ages of 65 and 69 and White, non-Hispanic. The largest proportion of transgender and cisgender beneficiaries were from the South. On average, transgender individuals had more months of enrollment than cisgender individuals. In adjusted models, aging TFN or TMN Medicare beneficiaries had the highest probability of each of the 25 health diagnoses studied relative to cisgender males or females. TFN beneficiaries had the highest burden of health diagnoses relative to all other groups.DiscussionThese findings document disparities in key health condition diagnoses among transgender Medicare beneficiaries relative to cisgender individuals. Future application of these methods will enable the study of rare and anatomy-specific conditions among hard-to-reach aging transgender populations and inform interventions and policies to address documented disparities.

Project description:IntroductionHealth research is one mechanism to improve population-level health and should generally match the health needs of populations. However, there have been limited data to assess the trends in national-level cardiovascular research output, even as cardiovascular disease [CVD] has become the leading cause of morbidity and mortality worldwide.Materials and methodsWe performed a time trends analysis of cardiovascular research publications (1999-2008) downloaded from Web of Knowledge using a iteratively-tested cardiovascular bibliometric filter with >90% precision and recall. We evaluated cardiovascular research publications, five-year running actual citation indices [ACIs], and degree of international collaboration measured through the ratio of the fractional count of addresses from one country against all addresses for each publication.Results and discussionGlobal cardiovascular publication volume increased from 40 661 publications in 1999 to 55 284 publications in 2008, which represents a 36% increase. The proportion of cardiovascular publications from high-income, Organization for Economic Cooperation and Development [OECD] countries declined from 93% to 84% of the total share over the study period. High-income, OECD countries generally had higher fractional counts, which suggest less international collaboration, than lower income countries from 1999-2008. There was an inverse relationship between cardiovascular publications and age-standardized CVD morbidity and mortality rates, but a direct, curvilinear relationship between cardiovascular publications and Human Development Index from 1999-2008.ConclusionsCardiovascular health research output has increased substantially in the past decade, with a greater share of citations being published from low- and middle-income countries. However, low- and middle-income countries with the higher burdens of cardiovascular disease continue to have lower research output than high-income countries, and thus require targeted research investments to improve cardiovascular health.
