Study ObjectiveTo compare the postoperative functional outcome and the total cost associated with outpatient vs inpatient care following complex hind-foot and ankle surgery.DesignRetrospective, cohort study.SettingTertiary care center.PatientsForty patients, American Society of Anesthesiologists 1-3, of either sex undergoing elective complex hind-foot and ankle surgery (fusion, osteotomy, or multiple ligament repair).InterventionsBoth inpatients and outpatients received a continuous perineural infusion of local anesthetic for 48 hours at the core of a multimodal analgesic regimen. Patients were retrospectively identified, and an outpatient cohort was matched to an inpatient cohort in a 1:1 ratio for age, sex, baseline functional score, and type of surgery.MeasurementsThe primary outcome was functional outcome upon discharge of the surgical program as measured by the Lower Extremity Functional Score. Secondary outcomes were the incidence of surgical or anesthetic complications and the total perioperative cost of care.ResultsPatients in both cohorts had similar functional outcome on discharge of the surgical program. Analgesia was effective in both groups, and no complications were reported. The cost of care for outpatients was 54% lower than that for inpatients.ConclusionThis retrospective study suggests that outpatient care including an ambulatory perineural infusion of local anesthetic may be a cost-effective alternative to inpatient care after complex foot and ankle surgery.Copyright © 2016 Elsevier Inc.
