We used an administrative healthcare claims database from September of the years 2008-2020 to identify shared patients with hypertension. The patients\u2019 behavior of visiting multiple medical facilities was extracted as graphical data, and we calculated density and centrality as indicators to evaluate the structure of the patient sharing network. Our findings indicate that density, reciprocity, and transitivity increased over time, and that centrality and PageRank were correlated.<\/jats:p>","DOI":"10.3233\/shti231140","type":"book-chapter","created":{"date-parts":[[2024,1,25]],"date-time":"2024-01-25T10:26:50Z","timestamp":1706178410000},"source":"Crossref","is-referenced-by-count":1,"title":["Analyzing Patient-Sharing Network Using an Administrative Claim Database in Japan"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8725-6508","authenticated-orcid":false,"given":"Tomoki","family":"Ishikawa","sequence":"first","affiliation":[{"name":"Institute For Health Economics and Policy, Japan"},{"name":"Hokkaido University, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihito","family":"Kako","sequence":"additional","affiliation":[{"name":"Institute of Industrial Science, The University of Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiromasa","family":"Yoshimoto","sequence":"additional","affiliation":[{"name":"Institute of Industrial Science, The University of Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junko","family":"Hattori","sequence":"additional","affiliation":[{"name":"Institute of Industrial Science, The University of Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuo","family":"Goda","sequence":"additional","affiliation":[{"name":"Institute of Industrial Science, The University of Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naohiro","family":"Mitsutake","sequence":"additional","affiliation":[{"name":"Institute For Health Economics and Policy, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO 2023 \u2014 The Future Is Accessible"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI231140","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,25]],"date-time":"2024-01-25T10:26:52Z","timestamp":1706178412000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI231140"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1,25]]},"ISBN":["9781643684567","9781643684574"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti231140","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,1,25]]}}}
