Bayesian Networks (BNs) derived from the administrative data were used to provide the descriptive models. Nearly half the patients in each stroke subtype were triaged as \u2018Urgent\u2019 (to be seen within 30 minutes). With a decrease in the urgency of triage categories, the proportion admitted within 8 hours decreased dramatically and the proportion of formal discharge increased. Notably, 45% of transient ischaemic attacks (TIAs) were categorized as \u2018Semi-urgent\u2019 (to be attended within 60 minutes), indicating an opportunity to improve emergency assessment of TIAs. The results illustrate the utility of hospital administrative data and the applicability of BNs for review of the current triage practices and subsequent impact.<\/jats:p>","DOI":"10.1177\/1460458211424475","type":"journal-article","created":{"date-parts":[[2011,12,21]],"date-time":"2011-12-21T19:04:03Z","timestamp":1324494243000},"page":"294-312","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Emergency department triaging of admitted stroke patients\u2014A Bayesian Network analysis"],"prefix":"10.1177","volume":"17","author":[{"given":"Shyamala G","family":"Nadathur","sequence":"first","affiliation":[{"name":"Monash University, Australia"}]},{"given":"James R","family":"Warren","sequence":"additional","affiliation":[{"name":"University of Auckland, New Zealand"}]}],"member":"179","published-online":{"date-parts":[[2011,12,21]]},"reference":[{"key":"e_1_3_2_2_2","first-page":"18","article-title":"The changing face of stroke.
