d="sp0055">DLI data were collected prospectively on all LVAD patients implanted between 2009 and 2013 at Columbia University Medical Center. Drive-line care was altered on June 1, 2011, from a dry sterile dressing without a standard anchoring device to a standardized kit, which included silver gauze dressing and a standard anchoring device. The silver dressing was used until the wound incorporated, with a minimum of 1 month.
d="sp0060">During the study period, 107 patients were implanted with LVADs before implementation of a standardized kit (Group A) and 159 thereafter (Group B). Median follow-up time (censoring at June 2011) for Group A was 8.73 (IQR 3.51 to 17.47) months and 11.65 (IQR 6.66 to 35.20) months for Group B (p = 0.17). DLI event rate improved from 0.18 to 0.07 event per patient-year, corresponding to a relative risk reduction of 62.5%. In addition, the 1-year freedom from infection was significantly increased in Group B (92.46%) compared with Group A (81.94%) (log rank = 0.036).
d="sp0065">The use of a standardized kit, including silver dressing and a standard anchoring device, leads to decrease in DLI with an absolute risk reduction of 11%. Routine use of these dressing techniques is warranted based on our findings, and may lead to reduction of complications related to infections.
