Predictive factors for satisfaction with surgery following anterior posterior same day spinal fusion.

Background: Patient satisfaction is an important measure of quality of care following spine surgery. Same-day anterior posterior circumferential spine surgery is a reliable technique used to achieve a successful lumbar arthrodesis. The purpose of this study is to identify predictive factors for 6-month patient satisfaction following 1-2 level same-day anterior and posterior spinal fusion. Methods: Adult patients undergoing 1-2 level anterior posterior fusion (APF) from 2018 to 2022 were identified from a single surgeon database. Patients undergoing APF were divided into two cohorts: (I) patients satisfied at 6 months; (II) patients not satisfied at 6 months. Pre-operative, intra-operative, perioperative, 6-week, and 6-month variables were assessed. Univariate, bivariate, and multivariable regression were performed. Threshold regression analysis was utilized to determine thresholds for continuous variables when significant on bivariate analysis. Results: A total of 97 consecutive patients who underwent 1-2 level anterior-posterior same-day lumbar fusion surgery were identified. Of these, 79 patients (81%) were satisfied at 6 months. The average age of all patients was 51 years [standard deviation (SD) 11 years]; 46 patients (47%) were female, 60 (62%) used opiates, and 7 (7%) had undergone prior laminectomy surgery. Bivariate analysis showed satisfied patients were less likely to be prior opiate users (57% Conclusions: Multivariable analysis identified week 6 satisfaction, VAS <5, no prior laminectomy, and no preoperative opiate use as independent predictors for 6-month satisfaction following anterior-posterior same-day spinal fusion surgery. These findings can help counsel patients and manage their expectations preoperatively, perioperatively, and during the 6-week visit.
