RESUMO
BACKGROUND: Patients with lumbar spinal pathology often suffer from anxiety and sleep disturbance, but correlations between anxiety and sleep disturbance and other patient-reported outcome measures (PROMs) before and after surgical intervention have not been explored. The purpose of this study is to analyze the correlations between patient-reported anxiety, sleep disturbance, and PROMs before and after lumbar decompression. METHODS: All patients undergoing elective, primary, lumbar decompression were retrospectively queried from a prospectively-maintained single spine surgeon database. Demographic and perioperative data and pre- and postoperative PROMs were extracted. Patient-Reported Outcome Measure Information System (PROMIS)-Anxiety, PROMIS-Sleep Disturbance (SD), PROMIS-Physical Function (PF), 9-Item Patient Health Questionnaire (PHQ-9), Visual Analog Scale (VAS)-Back, VAS-Leg, Oswestry Disability Index (ODI) were obtained preoperatively and through two years postoperatively. Pearson's correlation coefficients were calculated between PROMIS-Anxiety, PROMIS-SD, and the other PROMs of interest. RESULTS: PROMIS-Anxiety was positively correlated with PROMIS-SD (range: r = 0.473-0.828, p ≤ 0.006, all), PHQ-9 (range: r = 0.613--0.890, p ≤ 0.006, all), VAS-Back (range: r = -0.410-0.798, p ≤ 0.039, all), and ODI (range: r = 0.503-0.732, p ≤ 0.033, all) at all timepoints. PROMIS-Anxiety was negatively correlated with PROMIS-PF through 1 year postoperatively (range: r = -0.323- -0.729p ≤ 0.033, all). PROMIS-Anxiety was positively correlated to VAS-Leg at preoperative, 6-week, 12-week, and 2-year postoperative timepoints (range: r = 0.333--0.707, p ≤ 0.022, all). PROMIS-SD was positively correlated with PHQ-9 (range: r = 0.600-0.836), VASBack (range: r = 0.383-0.734), VAS-Leg (range: r = 0.399-0.811), and ODI (range: r = 0.404-0.812) at all timepoints (p ≤ 0.031, all). PROMIS-SD was negatively correlated with PROMIS-PF at all timepoints (range: r = -0.339-0.665, p ≤ 0.035, all). CONCLUSION: Patient-reported anxiety and sleep disturbance are significantly correlated with depressive burden, back pain, disability, and physical function, before and after lumbar decompression. Future studies should aim to determine the directionality of the associations and test interventions to improve health-related quality of life following lumbar decompression.
