Trends in nonoperative treatment modalities prior to cervical surgery and impact on patient-derived outcomes: Two-year analysis of 1522 patients from the prospective spine treatment outcome study

Abstract

Background: Effects of nonoperative treatments on surgical outcomes for patients who failed conservative management for cervical spine pathologies remain unknown. The objective is to describe conservative modality use in patients indicated for surgery for degenerative cervical spine conditions and its impact on perioperative outcomes. Methods: The current study comprises a retrospective review of a prospective multicenter database. A total of 1522 patients with 1-to 2-level degenerative cervical pathology who were undergoing surgical intervention were included. Outcome measures used were health-related quality-of-life scores, length of hospitalization, estimated blood loss, length of surgery, and return-to-work status at 2 weeks, 6 months, 1 year, and 2 years postoperatively. Patients were grouped by diagnosis (radiculopathy vs. myelopathy), then divided based on epidural injection(s), physical therapy (PT), or opioid use prior to enrollment. Univariate t-tests and χ2 tests were performed to determine differences between groups and impact on outcomes. Results: Among 1319 radiculopathy patients, 25.7% received preoperative epidural injections, 35.3% received PT, and 35.5% received opioids. Radiculopathy patients who received epidurals and PT had higher 1-year postoperative returnto- work rates (P
