Study Design: Retrospective.Objective: To determine the association between preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) scores with postoperative pain, narcotics use, and patient-reported outcomes (PRO) following a single-level anterior cervical discectomy and fusion (ACDF) procedure.Summary Of Background Data: There is a scarcity of prior literature on the ability of baseline PROMIS scores to predict clinical outcomes for patients undergoing ACDF procedures.Methods: Patients who underwent a primary ACDF were retrospectively reviewed and stratified into low and high disability cohorts. Preoperative PROMIS PF cohorts were tested for association with demographic and perioperative characteristics using chi-square analysis and one-way analysis of variance. Cohorts were tested for association with inpatient pain scores and narcotics consumption, as well as postoperative improvements in PROMIS PF, neck disability index (NDI), and visual analog scale (VAS) neck and arm pain using linear regression.Results: Ninety one patients were included: 39 low disability and 52 high disability. Inpatient postoperative VAS pain scores and narcotic consumption are also compared between cohorts. Patients with greater disability reported higher VAS pain scores (P = 0.003). However, patients in both cohorts consumed comparable amounts of narcotics (P = 0.926). Patients with greater preoperative disability demonstrated lower PROMIS PF scores, greater NDI scores, and greater VAS Neck scores at the preoperative baseline. However, patients demonstrated similar improvement of VAS neck and arm pain, as well as NDI at all postoperative timepoints. Patients with low disability reported worsened physical function at the 6 weeks timepoint.Conclusion: Patients with worse preoperative disability as measured by PROMIS PF reported increased pain but comparable narcotics consumption in the immediate postoperative period following a single-level ACDF procedure. Furthermore, patients experienced similar long-term postoperative improvement of PROs regardless of preoperative physical function. PROMIS PF can efficiently quantify physical function before and after the ACDF procedure as self-evaluated by patients.Level Of Evidence: 3. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate specific demographic and perioperative variables associated with higher inpatient pain scores following minimally invasive transforaminal lumbar interbody fusion (MIS TLIF).Methods: Patients who underwent a single-level, primary MIS TLIF were retrospectively reviewed. Perioperative outcomes were collected, and postoperative inpatient VAS pain scores were measured. Both bivariate and stepwise multivariate Poisson regressions with robust error variance were used to assess risk factors for average inpatient pain score ≥ 5.0. A final backward stepwise regression model was created using age, gender, smoking status, diabetes status, insurance status, BMI, comorbidity burden, pedicle screw laterality, operative time, and estimated blood loss.Results: A total of 255 patients undergoing primary, single-level MIS TLIF were included. Age less than 50 years, workers' compensation insurance, preoperative VAS pain score ≥ 7, and operative duration ≥ 110 min were associated with greater postoperative pain. However, other variables such as gender, BMI, smoking status, comorbidity burden, diabetes status, and pedicle screw laterality were not associated with increased postoperative pain.Conclusion: The results of this study suggest that younger age, workers' compensation, elevated preoperative pain scores, and longer operative times are independently associated with greater inpatient pain following TLIF. Surgeons can use this information to better assess which patients may require additional pain control following TLIF. Patient expectations of postoperative outcomes in regard to pain and recovery may also be better managed. These slides can be retrieved under Electronic Supplementary Material. (paragraph).
