Purpose / Aim of Study: The purpose of this study was to identify if the use of ciNPWT with “Prevena” reduces wound revision surgery in major lower (above ankle) atraumatic amputations. Materials and Methods: This is a retrospective cohort quality study at Nykøbing Falster Hospital, Region Sjaelland identifying al major amputations from 2010-2017. Patients amputated due to tumours were excluded. CiNPWT with “Prevena” was implemented on 1. June 2014 and defines the transition between the control group (2010-2013) and the intervention group (2015- 2017). Differences between the groups were analysed using the Chi-Squared test and unpaired parametric t-test with Welch correction. Statistical signifi- cance level was chosen to p <0.05. Findings / Results: We found 161 patients in the intervention group and 179 patients in the control group. Patients in the intervention group were signif- icantly younger (73.2 ± 9.6) compared to the control group (77.9 ± 11.6), p<0.001. Both groups were comparable in terms of gender as well as the pres- ence of diabetes and complicated wounds. We found 24 patients who needed revision in the intervention group (14.8%) and 29 (15.8%) in the control group in the immediate postoperative period of 2 months (p=0.79). Conclusions: We didn’t find any reduced rate of revision surgery in our study in patients treated with ciNPWT in the immediate postoperative days, but pa- tients receiving ciNPWT tend to go through fewer operative procedures. More research in ciNPWT in this field of use is needed. 143.
