INTRODUCTION Access site complication is the most common adverse event following endovascular intervention and when emergent operative repair of the common femoral artery (CFA) is needed, patient morbidity can be significantly increased. The intent of this project was to identify predictors of wound events after emergent operative repair of the CFA due to an access site complication. It was hypothesized that patients discharged to a facility would benefit from an ongoing relationship with health care professionals as evidenced by more consistent follow-up and lower wound complication rates. METHODS Patients who had a percutaneous CFA access complication and required emergent open CFA repair at an academic medical institution between 2015 and 2018 were included and the charts were reviewed retrospectively. Primary outcomes included wound complication and outpatient compliance with Vascular Surgery clinic visit. Dichotomous groups were evaluated by Chi-square test and continuous variables were evaluated by Student's T-test. Univariate and multivariate regression analyses were completed to assess risk factors contributing to wound event or failure of clinic follow up. RESULTS Forty-four patients were identified with emergent CFA repair due to an access complication between July 2015 and June 2018. Among this population, 33% of patients had wound complications and 27% were discharged to a facility. Among those discharged to a facility, the rate of follow-up to the vascular surgeon's clinic was significantly lower compared to those discharged to home (40% vs 85%, p<0.05), and the incidence of wound complications appeared greater but did not reach statistical significance (50% vs 27%, p=0.11). Univariate analysis indicated that kidney disease, albumin <3g/dL, and current smoking were predictive of wound complication, while on multivariate analysis, only kidney disease remained predictive (p<0.05, OR=22). The Modified Frailty Index (mFI) was not predictive of wound complications or compliance with follow-up. However, mFI did approach statistical significance when predicting discharge to a facility. DISCUSSION Despite the availability of medical personnel to arrange transportation and provide wound care in post-acute care facilities, patients who were discharged to a facility after CFA injury requiring emergent repair experienced lower compliance with clinic follow-up and may have suffered more wound complications. Strategies to improve compliance with patient follow-up and wound healing in patients sent to post-acute care facilities are warranted.
