    Data for 'Bringing public attention to disease into global health priority-setting'(opens in a new tab)

    Arroyo-Machado, Wenceslao; Ràfols, Ismael; A. Diaz-Faes, Adrian

    This dataset contains the data underlying the study Bringing public attention to disease into global health priority-setting. The study maps diseases from the Global Burden of Disease (GBD) 2023 classification across three dimensions, namely epidemiological burden, public attention and research effort, for the period 2016 to 2023. Burden is measured through disability-adjusted life years (DALYs) retrieved from the GBD 2023 release. Public attention is measured through monthly Wikipedia pageviews, restricted to human traffic, across all language editions. Research effort is measured through publications indexed in OpenAlex under the corresponding MeSH descriptors as a major topic. The deposit includes the manual mapping that links each GBD cause to MeSH descriptors and Wikipedia articles, the raw indicator files retrieved from each source, and the aggregated datasets used in the analysis. All processing scripts are available at https://github.com/Wences91/gbd_misalignment. Contents matching_2023.xlsx The core mapping of the study, produced manually and validated against external sources. The sheet Classification holds the four-level GBD 2023 hierarchy of 333 causes, after excluding injury-related causes. The sheet Mapping links each cause to its MeSH descriptors, with qualifiers where applicable, and to its primary Wikipedia article. In total, 236 specific diseases are matched, of which 129 belong to level 3 and 107 to level 4. Raw_data.zip Source data retrieved from each of the three dimensions, together with the lookup tables derived from the mapping. gbd_all_dalys_1423.csv - Global DALYs by cause and year. gbd_all_dalys_countries_1623_1.csv and gbd_all_dalys_countries_1623_2.csv - DALYs by cause, country and year, for the 25 countries where the selected Wikipedia languages hold official or national status. mesh_papers.csv and mesh_papers_with_q.csv - Publications indexed under each MeSH descriptor as a major topic, without and with qualifiers, extracted from OpenAlex. openalex_countries.csv - Country of the first author affiliation for each publication. wiki_pageviews_user.tsv - Monthly pageviews by Wikipedia article and language edition. level_3_MESH.tsv and level_3_Wikipedia.tsv - Lookup tables linking each specific disease to its MeSH descriptors and to its Wikipedia article. Aggregated_data.zip Analytical datasets built from the files above. Each record reports publication counts, pageviews and DALYs for the period 2016 to 2023. results_final_lv2.tsv - The 19 GBD level-2 disease groups. results_final_lv3.tsv - The 158 GBD level-3 diseases, of which 138 have complete data across the three dimensions. results_final_lv2_year.tsv - Level-2 disease groups broken down by publication year. results_final_lv2_country.tsv and results_final_lv3_country.tsv - Levels 2 and 3 disaggregated by language edition. Fourteen editions are included, of which German, Persian, Swahili and Vietnamese are analysed in the article.

    In Brazil, health policy formulation, particularly through Clinical Protocols and Therapeutic Guidelines (PCDTs), is significantly influenced by scientific evidence. The National Commission for the Incorporation of Technologies into the Unified Health System (CONITEC) approves these PCDTs to standardize healthcare practices, thereby exemplifying the nexus of scientific research and policy. This study analyzes the scientific literature referenced in the PCDTs approved by CONITEC, exploring the flow of knowledge from global scientific research to Brazil’s health policy. Our approach involved a data pipeline for collecting, preprocessing, and analyzing information from scientific publications cited in all CONITEC’s PCDT reports published until 2023. The process encompasses web scraping, pattern recognition, and bibliometric analysis. The study identified references predominantly from the United States and the United Kingdom, with notable contributions from Brazilian sources. Cited research is almost entirely written in English and published in high-impact factor English-language journals. These findings document the global influence on Brazil’s health policies, with a substantial portion of the cited scientific evidence originating from international sources.

    Background A central concern in global health priority-setting is whether the supply of scientific knowledge aligns with health needs and demands. This alignment is usually assessed by comparing research effort with disease burden, overlooking other type of “social demand” of disease, in particular whether diseases are socially visible and generate public attention. We develop an analytical framework that treats public attention and epidemiological burden as complementary dimensions of health demand and examines their alignment with knowledge supply. Methods We combine data on publications indexed in OpenAlex, disability-adjusted life years from the Global Burden of Disease, and Wikipedia pageviews for 2016 to 2023, as indicators of research effort, disease burden, and public attention, respectively. We map 19 disease groups and 138 specific diseases across these three dimensions. Ternary plots are used to position diseases according to their relative balance across dimensions and to identify diseases that are over- or under-represented in research effort relative to epidemiological burden and public attention. We compare Global North-South patterns using German, Persian, Swahili, and Vietnamese language areas to assess how these relationships vary across territories. Results The three dimensions show limited alignment. At the disease group level, cardiovascular diseases account for the largest share of disease burden, mental disorders attract the largest share of public attention, and neoplasms concentrate the largest share of research effort. Public attention and disease burden are weakly correlated at both group and specific disease levels, indicating that Wikipedia pageviews and DALYs capture distinct dimensions of health demand. Ternary plots reveal different forms of misalignment, with some diseases showing plots dominated by burden, others by research effort, and others by public attention. Territorial analyses add a further layer by showing that diseases follow disparate patterns of supply-demand (mis)alignment across different linguistic territories. Conclusions Public attention provides a complementary dimension for mapping global health needs and demands. Our approach identifies where scientific knowledge supply fails to match epidemiological and/or public attention, supporting more nuanced global health analysis that may be useful for priority-setting.
