To examine one proprietary research collaborative in detail, administrative data from Cosmos research collaborative (Epic Corporation) was analyzed over 27 months through the end of 2023. An increasing number of organizations participated in Cosmos across geographic regions and organization types between Quarter 4 2021 and end of 2023 (152 to 229 total organizations \u201clive\u201d on Cosmos). While distinct users increased 3-fold over this time period, user engagement remained low, with between 0.25 to 0.21 projects on average per user per quarter. There was a trend toward increased number of logins and time using the platform over the study period. Through 2024 there have been 54 total publications referencing Cosmos. Although adoption is increasing for Cosmos, opportunities remain to improve cross-organizational data collaborative engagement for this and similar platforms.<\/jats:p>","DOI":"10.3233\/shti250820","type":"book-chapter","created":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:32:09Z","timestamp":1754566329000},"source":"Crossref","is-referenced-by-count":1,"title":["A Longitudinal Analysis of Institutional Adoption, Use, and Dissemination of an EHR Vendor-Based Data Sharing Program"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8051-8102","authenticated-orcid":false,"given":"Melissa A.","family":"Gunderson","sequence":"first","affiliation":[{"name":"Center for Learning Health System Sciences, Department of Surgery, Institute for Health Informatics, University of Minnesota, Minneapolis, MN"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2318-7261","authenticated-orcid":false,"given":"David A.","family":"Dorr","sequence":"additional","affiliation":[{"name":"Oregon Health Sciences University, Portland, OR"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1422-9848","authenticated-orcid":false,"given":"Harry","family":"Freedman","sequence":"additional","affiliation":[{"name":"Epic Systems Corporation, Verona, WI"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5193-1663","authenticated-orcid":false,"given":"Genevieve B.","family":"Melton","sequence":"additional","affiliation":[{"name":"Center for Learning Health System Sciences, Department of Surgery, Institute for Health Informatics, University of Minnesota, Minneapolis, MN"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO 2025 \u2014 Healthcare Smart \u00d7 Medicine Deep"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI250820","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:32:09Z","timestamp":1754566329000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI250820"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,7]]},"ISBN":["9781643686080"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti250820","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,7]]}}}
