    Objective

    Cervical spondylotic myelopathy (CSM) can cause significant difficulty with driving and a subsequent reduction in an individual's quality of life due to neurological deterioration. The positive impact of surgery on postoperative patient-reported driving capabilities has been seldom explored.

    Methods

    The CSM module of the Quality Outcomes Database was utilized. Patient-reported driving ability was assessed via the driving section of the Neck Disability Index (NDI) questionnaire. This is an ordinal scale in which 0 represents the absence of symptoms while driving and 5 represents a complete inability to drive due to symptoms. Patients were considered to have an impairment in their driving ability if they reported an NDI driving score of 3 or higher (signifying impairment in driving duration due to symptoms). Multivariable logistic regression models were fitted to evaluate mediators of baseline impairment and improvement at 24 months after surgery, which was defined as an NDI driving score < 3.

    Results

    A total of 1128 patients who underwent surgical intervention for CSM were included, of whom 354 (31.4%) had baseline driving impairment due to CSM. Moderate (OR 2.3) and severe (OR 6.3) neck pain, severe arm pain (OR 1.6), mild-moderate (OR 2.1) and severe (OR 2.5) impairment in hand/arm dexterity, severe impairment in leg use/walking (OR 1.9), and severe impairment of urinary function (OR 1.8) were associated with impaired driving ability at baseline. Of the 291 patients with baseline impairment and available 24-month follow-up data, 209 (71.8%) reported postoperative improvement in their driving ability. This improvement seemed to be mediated particularly through the achievement of the minimal clinically important difference (MCID) in neck pain and improvement in leg function/walking. Patients with improved driving at 24 months noted higher postoperative satisfaction (88.5% vs 62.2%, p < 0.01) and were more likely to achieve a clinically significant improvement in their quality of life (50.7% vs 37.8%, p < 0.01).

    Conclusions

    Nearly one-third of patients with CSM report impaired driving ability at presentation. Seventy-two percent of these patients reported improvements in their driving ability within 24 months of surgery. Surgical management of CSM can significantly improve patients' driving abilities at 24 months and hence patients' quality of life.

    Impact of educational background on preoperative disease severity and postoperative outcomes among patients with lumbar spondylolisthesis: a Quality Outcomes Database study.
    (Journal of neurosurgery. Spine, 2024-05) Agarwal, Nitin; Chan, Andrew K; Bisson, Erica F; Glassman, Steven D; Foley, Kevin T; Shaffrey, Christopher I; Gottfried, Oren N; Tumialán, Luis M; Potts, Eric A; Shaffrey, Mark E; Coric, Domagoj; Knightly, John J; Ibrahim, Sufyan; Mitha, Rida; Michalopoulos, Giorgos; Park, Paul; Wang, Michael Y; Fu, Kai-Ming; Slotkin, Jonathan R; Asher, Anthony L; Virk, Michael S; Guan, Jian; Haid, Regis W; Chou, Dean; Bydon, Mohamad; Mummaneni, Praveen V

    Objective

    Deficiency in patient education has been correlated with increased disease-related morbidity and decreased access to care. However, the associations between educational level, preoperative disease severity, and postoperative outcomes in patients with lumbar spondylolisthesis have yet to be explored.

    Methods

    The spondylolisthesis dataset of the Quality Outcomes Database (QOD)-a cohort with prospectively collected data by the SpineCORe study team of the 12 highest enrolling sites with an 81% follow-up at 5 years -was utilized and stratified for educational level. Patients were classified into three categories (high school or less, graduate, or postgraduate). Patient-reported outcome measures (PROMs) documented at baseline and follow-up included Oswestry Disability Index (ODI) score, EQ-5D in quality-adjusted life years, and numeric rating scale (NRS) scores for back and leg pain. Disease severity was measured with PROMs. Postoperatively, patients also completed the North American Spine Society assessment to measure their satisfaction with surgery. Multivariable regression analysis was used to compare education level with disease severity and postoperative outcomes.

    Results

    A total of 608 patients underwent analysis, with 260 individuals (42.8%) at an educational level of high school or less. On univariate analysis, baseline disease severity was worse among patients with lower levels of education. On multivariable regression analysis, patients with postgraduate level of education had significantly lower ODI scores (β = -3.75, 95% CI -7.31 to -0.2, p = 0.039) compared to graduates, while the other PROMs were not associated with significant differences at baseline. Five years postoperatively, patients from various educational backgrounds exhibited similar rates of minimal clinically important differences in PROMs. Nevertheless, patients with the lowest educational level had higher ODI scores (27.1, p < 0.01), lower EQ-5D scores (0.701, p < 0.01), and higher NRS leg pain (3.0, p < 0.01) and back pain (4.0, p < 0.01) scores compared to those with graduate or postgraduate levels of education. The odds for postoperative satisfaction were also comparable between cohorts at 5 years (reference, graduate level; high school or less, OR 0.87, 95% CI 0.46-1.64, p = 0.659; postgraduate, OR 1.6, 95% CI 0.7-3.65, p = 0.262).

    Conclusions

    Lower patient education level was associated with a greater baseline disease severity in patients with lumbar spondylolisthesis. Surgery demonstrated similar benefits irrespective of educational background; however, individuals with lower educational level reported lower outcomes overall. This emphasizes the need for enhanced health literacy to mitigate disparities for reported outcomes.

    What is the effect of preoperative depression on outcomes after minimally invasive surgery for adult spinal deformity? A prospective cohort analysis.
    (J Neurosurg Spine, 2024-02-16) Agarwal, Nitin; Letchuman, Vijay; Lavadi, Raj Swaroop; Le, Vivian P; Aabedi, Alexander A; Shabani, Saman; Chan, Andrew K; Park, Paul; Uribe, Juan S; Turner, Jay D; Eastlack, Robert K; Fessler, Richard G; Fu, Kai-Ming; Wang, Michael Y; Kanter, Adam S; Okonkwo, David O; Nunley, Pierce D; Anand, Neel; Mundis, Gregory M; Passias, Peter G; Bess, Shay; Shaffrey, Christopher I; Chou, Dean; Mummaneni, Praveen V
    OBJECTIVE: Depression has been implicated with worse immediate postoperative outcomes in adult spinal deformity (ASD) correction, yet the specific impact of depression on those patients undergoing minimally invasive surgery (MIS) requires further clarity. This study aimed to evaluate the role of depression in the recovery of patients with ASD after undergoing MIS. METHODS: Patients who underwent MIS for ASD with a minimum postoperative follow-up of 1 year were included from a prospectively collected, multicenter registry. Two cohorts of patients were identified that consisted of either those affirming or denying depression on preoperative assessment. The patient-reported outcome measures (PROMs) compared included scores on the Oswestry Disability Index (ODI), numeric rating scale (NRS) for back and leg pain, Scoliosis Research Society Outcomes Questionnaire (SRS-22), SF-36 physical component summary, SF-36 mental component summary (MCS), EQ-5D, and EQ-5D visual analog scale. RESULTS: Twenty-seven of 147 (18.4%) patients screened positive for preoperative depression. The nondepressed cohort had an average of 4.83 levels fused, and the depressed cohort had 5.56 levels fused per patient (p = 0.267). At 1-year follow-up, 10 patients still reported depression, representing a 63% decrease. Postoperatively, both cohorts demonstrated improvement in their PROMs; however, at 1-year follow-up, those without depression had statistically better outcomes based on the EQ-5D, MCS, and SRS-22 scores (p < 0.05). Patients with depression continued to experience higher NRS leg scores at 1-year follow-up (3.63 vs 2.22, p = 0.018). After controlling for covariates, the authors found that depression significantly impacted only 1-year follow-up MCS scores (β = 8.490, p < 0.05). CONCLUSIONS: Depressed and nondepressed patients reported similar improvements after MIS surgery, except MCS scores were more likely to improve in nondepressed patients.
