Item Open Access Impact of Educational Background on Preoperative Disease Severity and Postoperative Outcomes Among Patients With Cervical Spondylotic Myelopathy.(Clinical spine surgery, 2023-12) Agarwal, Nitin; DiGiorgio, Anthony; Michalopoulos, Giorgos D; Letchuman, Vijay; Chan, Andrew K; Shabani, Saman; Lavadi, Raj Swaroop; Lu, Daniel C; Wang, Michael Y; Haid, Regis W; Knightly, John J; Sherrod, Brandon A; Gottfried, Oren N; Shaffrey, Christopher I; Goldberg, Jacob L; Virk, Michael S; Hussain, Ibrahim; Glassman, Steven D; Shaffrey, Mark E; Park, Paul; Foley, Kevin T; Pennicooke, Brenton; Coric, Domagoj; Upadhyaya, Cheerag; Potts, Eric A; Tumialán, Luis M; Fu, Kai-Ming G; Asher, Anthony L; Bisson, Erica F; Chou, Dean; Bydon, Mohamad; Mummaneni, Praveen VStudy design
Retrospective review of a prospectively maintained database.Objective
Assess differences in preoperative status and postoperative outcomes among patients of different educational backgrounds undergoing surgical management of cervical spondylotic myelopathy (CSM).Summary of background data
Patient education level (EL) has been suggested to correlate with health literacy, disease perception, socioeconomic status (SES), and access to health care.Methods
The CSM data set of the Quality Outcomes Database (QOD) was queried for patients undergoing surgical management of CSM. EL was grouped as high school or below, graduate-level, and postgraduate level. The association of EL with baseline disease severity (per patient-reported outcome measures), symptoms >3 or ≤3 months, and 24-month patient-reported outcome measures were evaluated.Results
Among 1141 patients with CSM, 509 (44.6%) had an EL of high school or below, 471 (41.3%) had a graduate degree, and 161 (14.1%) had obtained postgraduate education. Lower EL was statistically significantly associated with symptom duration of >3 months (odds ratio=1.68), higher arm pain numeric rating scale (NRS) (coefficient=0.5), and higher neck pain NRS (coefficient=0.79). Patients with postgraduate education had statistically significantly lower Neck Disability Index (NDI) scores (coefficient=-7.17), lower arm pain scores (coefficient=-1), and higher quality-adjusted life-years (QALY) scores (coefficient=0.06). Twenty-four months after surgery, patients of lower EL had higher NDI scores, higher pain NRS scores, and lower QALY scores (P<0.05 in all analyses).Conclusions
Among patients undergoing surgical management for CSM, those reporting a lower educational level tended to present with longer symptom duration, more disease-inflicted disability and pain, and lower QALY scores. As such, patients of a lower EL are a potentially vulnerable subpopulation, and their health literacy and access to care should be prioritized.Item Open Access Inferior Clinical Outcomes for Patients with Medicaid Insurance After Surgery for Degenerative Lumbar Spondylolisthesis: A Prospective Registry Analysis of 608 Patients.(World neurosurgery, 2022-08) Chan, Andrew K; Letchuman, Vijay; Mummaneni, Praveen V; Burke, John F; Agarwal, Nitin; Bisson, Erica F; Bydon, Mohamad; Foley, Kevin T; Shaffrey, Christopher I; Glassman, Steven D; Wang, Michael Y; Park, Paul; Potts, Eric A; Shaffrey, Mark E; Coric, Domagoj; Knightly, John J; Fu, Kai-Ming; Slotkin, Jonathan R; Asher, Anthony L; Virk, Michael S; Kerezoudis, Panagiotis; Alvi, Mohammed A; Guan, Jian; Haid, Regis W; DiGiorgio, AnthonyBackground
It remains unclear how type of insurance coverage affects long-term, spine-specific patient-reported outcomes (PROs). This study sought to elucidate the impact of insurance on clinical outcomes after lumbar spondylolisthesis surgery.Methods
The prospective Quality Outcomes Database registry was queried for patients with grade 1 degenerative lumbar spondylolisthesis who underwent single-segment surgery. Twenty-four-month PROs were compared and included Oswestry Disability Index, Numeric Rating Scale (NRS) back pain, NRS leg pain, EuroQol-5D, and North American Spine Society Satisfaction.Results
A total of 608 patients undergoing surgery for grade 1 degenerative lumbar spondylolisthesis (mean age, 62.5 ± 11.5 years and 59.2% women) were selected. Insurance types included private insurance (n = 319; 52.5%), Medicare (n = 235; 38.7%), Medicaid (n = 36; 5.9%), and Veterans Affairs (VA)/government (n = 17; 2.8%). One patient (0.2%) was uninsured and was removed from the analyses. Regardless of insurance status, compared to baseline, all 4 cohorts improved significantly regarding ODI, NRS-BP, NRS-LP, and EQ-5D scores (P < 0.001). In adjusted multivariable analyses, compared with patients with private insurance, Medicaid was associated with worse 24-month postoperative Oswestry Disability Index (β = 10.2; 95% confidence interval [CI], 3.9-16.5; P = 0.002) and NRS leg pain (β =1.3; 95% CI, 0.3-2.4; P = 0.02). Medicaid was associated with worse EuroQol-5D scores compared with private insurance (β = -0.07; 95% CI -0.01 to -0.14; P = 0.03), but not compared with Medicare and VA/government insurance (P > 0.05). Medicaid was associated with lower odds of reaching ODI minimal clinically important difference (odds ratio, 0.2; 95% CI, 0.03-0.7; P = 0.02) compared with VA/government insurance. NRS back pain and North American Spine Society satisfaction did not differ by insurance coverage (P > 0.05).Conclusions
Despite adjusting for potential confounding variables, Medicaid coverage was independently associated with worse 24-month PROs after lumbar spondylolisthesis surgery compared with other payer types. Although all improved postoperatively, those with Medicaid coverage had relatively inferior improvements.
