One of the cited issues with EHRs is the human\u2013computer interaction, as exhibited by the excessive number of interactions with the interface, which reduces clinician efficiency. In contrast, real-time location systems (RTLS)\u2014technologies that can track the location of people and objects\u2014have been shown to increase clinician efficiency. RTLS can improve patient flow in part through the optimization of patient verification activities. However, the data collected by RTLS have not been effectively applied to optimize interaction with EHR systems.<\/jats:p>\n Objectives\u2003We conducted a pilot study with the intention of improving the human\u2013computer interaction of EHR systems by incorporating a RTLS. The aim of this study is to determine the impact of RTLS on process metrics (i.e., provider time, number of rooms searched to find a patient, and the number of interactions with the computer interface), and the outcome metric of patient identification accuracy<\/jats:p>\n Methods\u2003A pilot study was conducted in a simulated emergency department using a locally developed camera-based RTLS-equipped EHR that detected the proximity of subjects to simulated patients and displayed patient information when subjects entered the exam rooms. Ten volunteers participated in 10 patient encounters with the RTLS activated (RTLS-A) and then deactivated (RTLS-D). Each volunteer was monitored and actions recorded by trained observers. We sought a 50% improvement in time to locate patients, number of rooms searched to locate patients, and the number of mouse clicks necessary to perform those tasks.<\/jats:p>\n Results\u2003The time required to locate patients (RTLS-A\u2009=\u200911.9\u2009\u00b1\u20092.0\u2009seconds vs. RTLS-D\u2009=\u200936.0\u2009\u00b1\u20095.7\u2009seconds, p\u2009<\u20090.001), rooms searched to find patient (RTLS-A\u2009=\u20091.0\u2009\u00b1\u20091.06 vs. RTLS-D\u2009=\u20093.8\u2009\u00b1\u20090.5, p\u2009<\u20090.001), and number of clicks to access patient data (RTLS-A\u2009=\u20091.0\u2009\u00b1\u20090.06 vs. RTLS-D\u2009=\u20094.1\u2009\u00b1\u20090.13, p\u2009<\u20090.001) were significantly reduced with RTLS-A relative to RTLS-D. There was no significant difference between RTLS-A and RTLS-D for patient identification accuracy.<\/jats:p>\n Conclusion\u2003This pilot demonstrated in simulation that an EHR equipped with real-time location services improved performance in locating patients and reduced error compared with an EHR without RTLS. Furthermore, RTLS decreased the number of mouse clicks required to access information. This study suggests EHRs equipped with real-time location services that automates patient location and other repetitive tasks may improve physician efficiency, and ultimately, patient safety.<\/jats:p>","DOI":"10.1055\/s-0038-1675812","type":"journal-article","created":{"date-parts":[[2018,11,21]],"date-time":"2018-11-21T23:57:49Z","timestamp":1542844669000},"page":"841-848","source":"Crossref","is-referenced-by-count":5,"title":["The Impact of a Location-Sensing Electronic Health Record on Clinician Efficiency and Accuracy: A Pilot Simulation Study"],"prefix":"10.1055","volume":"09","author":[{"given":"Kevin","family":"King","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, University of Texas Health Science Center at San Antonio, San Antonio, Texas, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Quarles","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Texas at San Antonio, San Antonio, Texas, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vaishnavi","family":"Ravi","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Texas at San Antonio, San Antonio, Texas, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tanvir","family":"Chowdhury","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Texas at San Antonio, San Antonio, Texas, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donia","family":"Friday","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, San Antonio Uniformed Services Health Education Consortium, San Antonio, Texas, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Craig","family":"Sisson","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, University of Texas Health Science Center at San Antonio, San Antonio, Texas, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yusheng","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Texas at San Antonio, San Antonio, Texas, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,11,21]]},"container-title":["Applied Clinical Informatics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0038-1675812.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T21:02:28Z","timestamp":1557176548000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0038-1675812"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2018,10,3]]},"published-print":{"date-parts":[[2018,10]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0038-1675812","relation":{},"ISSN":["1869-0327"],"issn-type":[{"value":"1869-0327","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,10]]}}}
