Abstract

Abstract: Background: The development of a core outcome set (COS), defined as an agreed minimum set of outcome domains that should be measured and reported in all trials of a specific disease, aims to increase the relevance of study findings to stakeholder groups and improve standardization. Objectives: As the first step in developing a COS for venous thromboembolism (VTE) treatment studies, we aimed to generate an inclusive list of unique outcomes reported in previous VTE treatment studies and classify them into domains and core areas. Methods: MEDLINE, Embase and CENTRAL were searched for prospective studies reporting on interventions for VTE in non‐pregnant adults. Study selection and data extraction were performed in blocks based on publication date, starting with 2015–2020 and subsequent 1‐year periods, until no new outcome was identified. Outcomes were classified into domains, which are groups of closely related outcomes, and domains into four core areas including death, pathophysiological manifestations/abnormalities, life impact, and resource use. Results: Of 7100 records identified, 240 publications were included, representing 165 distinct studies. A total of 205 unique outcomes were identified that were grouped into 48 domains; 30 (13%) studies covered at least three core areas; death was included in 102 (43%), pathophysiological manifestations/abnormalities in 218 (91%), life impact in 41 (17%), and resource use in 25 (10%) studies. Conclusion: Most VTE treatment studies evaluated pathophysiological features of VTE, but few studies reported outcomes that measured life impact or resource use. The findings will inform next steps in the development of a COS for VTE treatment studies.
