To determine if driveline infection is related to dressing change frequency in hospitalized adult patients with newly implanted left ventricular assist devices (LVAD).
Guidelines do not exist for the frequency of driveline exit-site dressing change in hospitalized patients resulting in wide variation in practice.
A retrospective chart review was conducted on 68 patients implanted with a HeartMate II LVAD between August 2008 and September 2013 at an urban medical center.
No driveline infections were found. Frequency of the driveline dressing change varied from daily, three times a week, and weekly. The daily dressing change group was younger in age compared to the weekly group (p = 0.005) and three times a week group (p = 0.001). No other differences were found.
Driveline infections do not appear to be related to the frequency of dressing change in this population. Our data and other studies on this topic thus far are too limited to draw definitive conclusions about optimal frequency of dressing change for infection prevention.
确定住院的新植入左心室辅助装置（LVAD）的成年患者中，驱动线感染是否与换药频率相关。
目前尚无针对住院患者驱动线出口部位换药频率的指南，这导致实际操作差异很大。
对2008年8月至2013年9月期间在一家城市医疗中心植入HeartMate II LVAD的68例患者进行回顾性病历审查。
未发现驱动线感染。驱动线换药频率从每日、每周三次到每周一次不等。与每周换药组（p = 0.005）和每周三次换药组（p = 0.001）相比，每日换药组年龄更小。未发现其他差异。
在该人群中，驱动线感染似乎与换药频率无关。我们的数据以及迄今为止关于该主题的其他研究都过于有限，无法就预防感染的最佳换药频率得出明确结论。
