Continuous monitoring of VAD parameters and their adherence to guidelines are crucial to detect problems in an early stage to optimize outcomes. A telephone intervention algorithm for VAD outpatients was developed, clinically implemented and evaluated. During the phone calls, a structured inquiry of pump parameters, alarms, blood pressure, INR, body weight and temperature, exit\u2010site status and heart failure symptoms was performed and electronically categorized by an algorithm into 5 levels of severity. VAD outpatient outcomes without (<jats:italic>n<\/jats:italic>\u2009=\u200971) and with bi\u2010weekly telephone interviews in their usual care (<jats:italic>n<\/jats:italic>\u2009=\u200925) were conducted using proportional hazard Cox regression, with risk adjustment based on a propensity score model computed from demographics and risk factors. From February 2015 through October 2017, 25 patients (<jats:italic>n<\/jats:italic>\u2009=\u20093 HeartMate II, <jats:italic>n<\/jats:italic>\u2009=\u20094 HeartMate 3 and <jats:italic>n<\/jats:italic>\u2009=\u200918 HeartWare HVAD) underwent 637 telephone interventions. In 57.5% of the calls no problems were identified, 3.9% were recalled on the next day because of alarms. In 26.5% (<jats:italic>n<\/jats:italic>\u2009=\u2009169), the VAD Coordinator had to refer to the physician due to elevated blood pressure (<jats:italic>n<\/jats:italic>\u2009=\u2009125, &gt;85 mm Hg), INR\u2009&lt;\u20092.0 or\u2009&gt;\u20094.0 (<jats:italic>n<\/jats:italic>\u2009=\u200924) or edema (<jats:italic>n<\/jats:italic>\u2009=\u200910), 11.9% of the calls led to a follow\u2010up because of equipment or exit\u2010site problems. Propensity\u2010adjusted 2\u2010year survival (89% vs. 57%, <jats:italic>P<\/jats:italic>\u2009=\u20090.027) was significantly higher for the telephone intervention group. Continuous, standardized communication with VAD outpatients is important for early detection of upcoming problems and leads to significantly improved survival.<\/jats:p>","DOI":"10.1111\/aor.13155","type":"journal-article","created":{"date-parts":[[2018,5,25]],"date-time":"2018-05-25T11:09:20Z","timestamp":1527246560000},"page":"961-969","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["A
