Abstract

Study Design: A retrospective analysis of data from the Healthcare Cost and Utilization Project Nationwide Readmissions Database (HCUP-NRD).Purpose: To identify the perioperative characteristics associated with 30-day and 90-day readmission due to intestinal bowel obstructions(IBOs) following posterior lumbar fusion (PLF) procedure.Overview of Literature: PLF procedures are used to repair spinal injuries and curvature deformities. IBO is a common surgical complicationand its repair often necessitates surgery that increases the readmission rates and healthcare costs. Previous studies haveidentified the preoperative risk factors for 30-day readmissions in PLF; however, no study has specifically investigated IBO or identifiedrisk factors for 90-day readmissions.Methods: Data on demographic characteristics and medical comorbidities of patients who underwent PLF with subsequent readmissionwere obtained from the HCUP-NRD. The perioperative characteristics that were significantly different between patients readmittedwith and without an active diagnosis of IBO were identified with bivariate analysis for both 30-day and 90-day readmissions. Thesignificant characteristics were then included in a multivariate analysis to identify those that were independently associated with 30-day and 90-day readmissions.Results: Drug abuse (odds ratio [OR], 4.00), uncomplicated diabetes (OR, 2.06), having Medicare insurance (OR, 1.65), age 55–64years (OR, 2.42), age 65–79 years (OR, 2.77), and age >80 years (OR, 3.87) were significant risk factors for 30-day readmission attributableto IBO after a PLF procedure.Conclusions: Of the several preoperative risk factors identified for readmission with IBO after PLF surgery, drug abuse had the strongestassociation and was likely to be the most clinically relevant factor.
