This study aims to determine the impact of preoperative depression on PROs in single vs multilevel ACDF procedures.Methods Eligible primary single or multilevel ACDF procedures were retrospectively reviewed from 2015 to 2020 using a surgical database. PROs included visual analog scale (VAS), Neck Disability Index (NDI), 12-Item Short Form Physical Composite Summary and Mental Composite Summary (SF-12 PCS and MCS), and Patient-Reported Outcomes Measurement Information System physical function (PROMIS PF). PROs were collected preoperatively and at 6 weeks, 12 weeks, 6 months, and 1 year postoperatively. Patients were stratified into 3 groups based on Patient Health Questionnaire-9 (PHQ-9) score. Differences in PROs were assessed based on preoperative depression severity or both preoperative depression severity and number of operative levels.Results Our patient cohort included 42 individuals with minimal preoperative depressive symptoms, 32 having mild and 27 having moderate to severe. Baseline PRO values were significantly different between groups (all P < 0.01). Improvement significantly differed between groups at 6 weeks for VAS arm, NDI, and SF-12 MCS (all P < 0.05), and at 12 wweeks for VAS neck, NDI, SF-12 PCS and MCS, and PROMIS PF (all P < 0.05). SF-12 PCS and MCS at 6 months and VAS arm and SF-12 MCS at 1 year demonstrated significant intergroup differences (all P < 0.05). VAS arm at 1 year (P = 0.029), NDI at 12 weeks (P = 0.034), PROMIS PF at 6 weeks (P = 0.038), and SF-MCS at all postoperative time points were impacted by both preoperative depression severity and number of levels fused.Conclusion Depression severity impacted recovery of pain, disability, and physical function preoperatively and at intermittent postoperative time points. Both severity and multilevel procedures impacted pain and mental health at intermittent postoperative time points. In addition to depression, multilevel ACDF procedures are an additional factor that must be considered in expected improvement of postoperative outcomes.Level of Evidence 4.Clinical Relevance Multilevel ACDF procedures and preoperative depression severity both impact postoperative pain, disability, and physical function.
