The devices\u2019 usability impacts patients\u2019 safety and quality of life. In this study, an eye tracking supported human factors testing was performed to reveal problems during use and test the trainings\u2019 effectiveness. In total 32 HeartWare HVAD patients (including 6 pre-VAD patients) and 3 technical experts as control group performed a battery change (BC) and a controller change (CC) as an everyday and emergency scenario on a training device. By tracking the patients\u2019 gaze point, task duration and pump-off time were evaluated. Patients with LVAD support \u22651\u00a0year showed significantly shorter BC task duration than patients with LVAD support &lt;1\u00a0year (<jats:italic>p<\/jats:italic>\u00a0=\u20090.008). In contrast their CC task duration (<jats:italic>p<\/jats:italic>\u00a0=\u20090.002) and pump-off times (median\u2009=\u200912.35\u00a0s) were higher than for LVAD support patients &lt;1\u00a0year (median\u2009=\u20095.3\u00a0s) with <jats:italic>p<\/jats:italic>\u00a0=\u20090.001. The shorter BC task duration for patients with LVAD support \u22651\u00a0year indicate that with time patients establish routines and gain confidence using their device. The opposite effect was found for CC task duration and pump-off times. This implies the need for intermittent re-training of less frequent tasks to increase patients\u2019 safety.<\/jats:p>","DOI":"10.1007\/s10916-021-01729-4","type":"journal-article","created":{"date-parts":[[2021,3,25]],"date-time":"2021-03-25T23:10:28Z","timestamp":1616713828000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Eye Tracking Supported Human Factors Testing Improving Patient Training"],"prefix":"10.1007","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1337-2191","authenticated-orcid":false,"given":"Kerrin Elisabeth","family":"Weiss","sequence":"first","affiliation":[]},{"given":"Christoph","family":"Hoermandinger","sequence":"additional","affiliation":[]},{"given":"Marcus","family":"Mueller","sequence":"additional","affiliation":[]},{"given":"Marianne","family":"Schmid Daners","sequence":"additional","affiliation":[]},{"given":"Evgenij V.","family":"Potapov","sequence":"additional","affiliation":[]},{"given":"Volkmar","family":"Falk","sequence":"additional","affiliation":[]},{"given":"Mirko","family":"Meboldt","sequence":"additional","affiliation":[]},{"given":"Quentin","family":"Lohmeyer","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,3,25]]},"reference":[{"key":"1729_CR1","doi-asserted-by":"publisher","first-page":"2388","DOI":"10.1093\/eurheartj\/ehn309","volume":"29","author":"K Dickstein","year":"2008","unstructured":"Dickstein K, Cohen-Solal A, Filippatos G, McMurray JJ V, Ponikowski P, Poole-Wilson PA, et al.
