Abstract
PURPOSE
Establishing research capacity in low- and middle-income countries (LMICs) is key for improving the outcomes of patients with hematologic diseases globally. Few studies have analyzed the contributions of LMICs to global hematology. The American Society of Hematology Meeting (ASH) is the largest international academic event where peer-reviewed contributions in our field are presented.
METHODS
In this cross-sectional analysis, all abstracts accepted to ASH 2018 selected for a poster or oral presentation were reviewed. Those that had a contributing author from an LMIC were identified. The proportion of LMIC abstracts across categories was analyzed. Country of origin, high-income country participation, the presence of a conflict of interest (COI), and sponsorship were determined.
RESULTS
From 4,871 abstracts reviewed, 506 had a contributing author from an LMIC (10.4%), with 277 (54.7%) contributions in partnership with a high-income country. LMIC-independent contributions corresponded to 19 of 1,026 oral abstracts (1.9%) and 209 of 3,845 posters (5.4%). Most abstracts from LMICs were clinical (n = 311; 61.5%) and multicentric in nature (n = 353; 69.8%). COI statements with the pharmaceutical industry were common (n = 214; 42.3%). Collaboration between LMICs was infrequent (n = 33; 6.5%). Upper-middle-income countries had 466 participations (81.5%), in comparison with 96 (16.8%) in low-middle-income and 10 (1.7%) in low-income countries.
CONCLUSION
LMICs were responsible for a small fraction of abstracts at ASH18; low-income countries were practically absent. Almost half of accepted works represented a form of international collaboration, with clinical, multicenter studies predominating and COI disclosures a frequent and unexpected feature, reflecting the instrumental nature of LMIC participation and a lack of independent, robust, locally developed hematology research.
