The vital signs of a patient can indicate this up to 24 hours before such an incident happens. Healthcare professionals use Early Warning Score (EWS) as a common tool in healthcare facilities to indicate the health status of a patient. However, the chance of survival of an outpatient could be increased if a mobile EWS system would monitor them during their daily activities to be able to alert in case of danger. Because of limited healthcare professional supervision of this health condition assessment, a mobile EWS system needs to have an acceptable level of reliability - even if errors occur in the monitoring setup such as noisy signals and detached sensors. In earlier works, a data reliability validation technique has been presented that gives information about the trustfulness of the calculated EWS. In this paper, we propose an EWS system enhanced with the self-aware property confidence, which is based on fuzzy logic. In our experiments, we demonstrate that - under adverse monitoring circumstances (such as noisy signals, detached sensors, and non-nominal monitoring conditions) - our proposed Self-Aware Early Warning Score (SA-EWS) system provides a more reliable EWS than an EWS system without self-aware properties.<\/jats:p>","DOI":"10.1007\/s11036-019-01324-5","type":"journal-article","created":{"date-parts":[[2019,8,29]],"date-time":"2019-08-29T12:15:18Z","timestamp":1567080918000},"page":"691-708","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Confidence-Enhanced Early Warning Score Based on Fuzzy Logic"],"prefix":"10.1007","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1112-141X","authenticated-orcid":false,"given":"Maximilian","family":"G\u00f6tzinger","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arman","family":"Anzanpour","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iman","family":"Azimi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nima","family":"TaheriNejad","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Axel","family":"Jantsch","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amir M.","family":"Rahmani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pasi","family":"Liljeberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2019,8,29]]},"reference":[{"key":"1324_CR1","unstructured":"WHO Chronic diseases and health promotion, Retr. on June 2017. http:\/\/www.who.int\/chp\/en\/"},{"key":"1324_CR2","doi-asserted-by":"crossref","unstructured":"McGaughey J, Alderdice F, Fowler R, Kapila A, Mayhew A, Moutray M (2007) Outreach and early warning systems (ews) for the prevention of intensive care admission and death of critically ill adult patients on general hospital wards.
