Hospitalization and Death in the First 30 days After Outpatient Lower Extremity Arterial Stenting

Abstract : Purpose: To compare the safety of outpatient versus inpatient endovascular treatment of lower extremity arterial disease (LEAD) using real-life data. Materials and methods: This retrospective observational study used real-life data from the French national health data information system on adult patients who underwent stenting for LEAD between 2013 and 2016. The outcomes of interest were all-cause mortality, all-cause hospitalization, planned hospitalization, and unplanned hospitalization at day 3 and day 30 after the index endovascular intervention for LEAD revascularization. A propensity score was used to control for indication bias. Outcome rates in outpatient and inpatient settings were compared with the Poisson regression model. Sensitivity analyses were performed by varying the definition of the outcomes of interest. Results: During the study period, 26,715 interventions were performed among which 2819 (10.6%) were in outpatient settings. Outpatients were slightly younger than inpatients (64.73 ± 10.68 vs. 68.10 ± 11.50, respectively). The percentage of women patients was similar: 19.8% in the outpatient group and 27.2% in the inpatient group. Within 30 days after discharge, 73 patients (.31%) and 2 (.07%) patients (p = .02) died in the inpatient group and outpatient group, respectively. The death and rehospitalization rate were similar: 3.8 and 3.5 per 1000 person-months for inpatients and outpatients, respectively. No difference was observed after adjusting for patients' case-mix in the regression model (RR = .99; 95% CI [.82-1.19]). Conclusions: Outpatient stenting for LEAD did not present any additional risk of early postoperative rehospitalization or death compared with inpatient stenting.
