Sex-based differences in loss of independence after lower extremity bypass surgery

Introduction: This study analyzes sex-based differences in the risk of discharge to a nonhome facility (loss of independence) after lower extremity revascularization and resultant outcomes. Methods: Data from the NSQIP database for years 2015–2017 was utilized to assess sex-based differences in loss of independence and associated unplanned readmission and 30-day amputation using chi-square, student t-test, and multivariate logistic regression analyses where appropriate. Results: There was increased loss of independence in women (34.9% vs. 26.1 %, p <.01) and associated increase in unplanned readmission (18.4% vs. 13.6 %, p =.01) and length of stay (12.1 days vs 6.5 days, p <.01). Endovascular revascularization was associated with decreased likelihood of loss of independence (OR 0.43, CI 0.36–0.50). Conclusion: Loss of independence after lower extremity bypass surgery affects women more than men and it is associated with worse postoperative outcomes.
