Abstract

Study ObjectiveTo examine, with a large database, the effect of postoperative epidural analgesia (vs systemic analgesia) on mortality after colectomy is unclear.DesignRetrospective cohort (database) design.SettingMedicare beneficiaries undergoing elective colectomy.PatientsWe examined a cohort of 12 817 patients obtained from a 5% nationally random sample of Medicare beneficiaries from 1997 to 2001 who underwent elective partial excision of the large intestine.InterventionsPatients were divided into two groups depending on the presence or absence of billing for postoperative epidural analgesia (Current Procedural Terminology code 01996).MeasurementsThe primary outcomes assessed were death at 7 and 30 days after the procedure. The rates of major morbidity were also compared. Multivariate regression analysis incorporating race, gender, age, comorbidities, hospital size, hospital teaching status, and hospital technology status was performed to determine whether the presence of postoperative epidural analgesia had an independent effect on mortality or major morbidity.Main ResultsMultivariate regression analysis revealed that there was no difference between the groups with regard to overall major morbidity; however, the presence of epidural analgesia was associated with a significantly lower odds of death at 7 days (odds ratio, 0.35; 95% confidence interval, 0.21-0.59; P < 0.0001) and 30 days (odds ratio, 0.54; 95% confidence interval, 0.42-0.70; P < 0.0001) after surgery.ConclusionsThe presence of postoperative epidural analgesia may decrease the odds of death after elective colectomy; however, the mechanism of such a benefit is not clear from our analysis.
