836 Factors Associated With Non-Routine Discharge Following Spinal Cord Stimulator Insertion Surgery

Abstract

INTRODUCTION: Neuropathic pain can lead to functional impairment and psychological stress in the patients. Spinal cord stimulation offers pain alleviation that can lead to improvement in quality of life and functionality. METHODS: The national inpatient sample (NIS) 2016-2019 was used to identify patients undergoing surgery for spinal cord stimulator (SCS) insertion. The patients were divided based on their discharge disposition to either routine or non-routine discharge groups. RESULTS: A total of 1786 patients, with a mean age of 60.0 (14.0) years and 1031 (57.7%) females, were enrolled in the study. The non-routine discharge group comprised 462 (25.9%) patients that were not discharged to home or self-care. The univariate analysis observed a higher risk for nonroutine discharge following SCS insertion to be associated with higher age (64.3 vs. 58.5 years, p < 0.01), female sex (64.3% vs. 55.4%, p<0.01), insurance type (p<0.01), and postoperative complications (2.6% vs. 0.7, p < 0.01). On the multivariate regression model, a significant association of nonroutine discharge was observed for age (OR: 1.02 (1.01 – 1.03), p < 0.01), female sex (OR: 1.44 (1.14 - 1.81), p < 0.01), Hispanic race (OR: 1.85 (1.27 - 2.69), p < 0.01), Medicare insurance (OR: 1.71 (1.26 - 2.32), p < 0.01), and postoperative complication (OR: 3.50 (1.43 - 8.53), p < 0.01). CONCLUSIONS: The study found that non-routine discharge following SCS insertion was independently associated with higher age, female sex, Hispanic race, medicare insurance coverage, and postoperative complications.
