Item Open Access Differences in postoperative quality of life in young, early elderly, and late elderly patients undergoing surgical treatment for degenerative cervical myelopathy.(Journal of neurosurgery. Spine, 2022-03) Croci, Davide M; Sherrod, Brandon; Alvi, Mohammed Ali; Mummaneni, Praveen V; Chan, Andrew K; Bydon, Mohamad; Glassman, Steven D; Foley, Kevin T; Potts, Eric A; Shaffrey, Mark E; Coric, Domagoj; Knightly, John J; Park, Paul; Wang, Michael Y; Fu, Kai-Ming; Slotkin, Jonathan R; Asher, Anthony L; Than, Khoi D; Gottfried, Oren N; Shaffrey, Christopher I; Virk, Michael S; Bisson, Erica FObjective
Cervical spondylotic myelopathy (CSM) is a common progressive spine disorder affecting predominantly middle-aged and elderly populations. With increasing life expectancy, the incidence of CSM is expected to rise further. The outcomes of elderly patients undergoing CSM surgery and especially their quality of life (QOL) postoperatively remain undetermined. This study retrospectively reviewed patients to identify baseline differences and validated postoperative patient-reported outcome (PRO) measures in elderly patients undergoing CSM surgery.Methods
The multi-institutional, neurosurgery-specific NeuroPoint Quality Outcomes Database was queried to identify CSM patients treated surgically at the 14 highest-volume sites from January 2016 to December 2018. Patients were divided into three groups: young (< 65 years), early elderly (65-74 years), and late elderly (≥ 75 years). Demographic and PRO measures (Neck Disability Index [NDI] score, modified Japanese Orthopaedic Association [mJOA] score, EQ-5D score, EQ-5D visual analog scale [VAS] score, arm pain VAS, and neck pain VAS) were compared among the groups at baseline and 3 and 12 months postoperatively.Results
A total of 1151 patients were identified: 691 patients (60%) in the young, 331 patients (28.7%) in the early elderly, and 129 patients (11.2%) in the late elderly groups. At baseline, younger patients presented with worse NDI scores (p < 0.001) and lower EQ-5D VAS (p = 0.004) and EQ-5D (p < 0.001) scores compared with early and late elderly patients. No differences among age groups were found in the mJOA score. An improvement of all QOL scores was noted in all age groups. On unadjusted analysis at 3 months, younger patients had greater improvement in arm pain VAS, NDI, and EQ-5D VAS compared with early and late elderly patients. At 12 months, the same changes were seen, but on adjusted analysis, there were no differences in PROs between the age groups.Conclusions
The authors' results indicate that elderly patients undergoing CSM surgery achieved QOL outcomes that were equivalent to those of younger patients at the 12-month follow-up.Item Open Access High Prevalence of Cervical Myelopathy among Hip Fracture Patients(Operative Techniques in Orthopaedics, 2023-12-01) Zhang, H; Buell, T; Baldwin, E; Dalton, T; Crutcher, C; Abd-El-Barr, MM; Foster, N; Goodwin, CR; Erickson, MHip fractures are devastating injuries for the elderly and an increasing burden to the healthcare system. Cervical spondylotic myelopathy (CSM), as a common cause of disability, instability, and falls in the elderly population, places patients at risk for hip fracture, and myelopathic patients are associated with increased complications after hip surgery. Myelopathy's relationship with hip fractures and impact, however, is not well understood. This study sought to 1) determine the prevalence of CSM among hip fracture patients and 2) hypothesized that hip fractures in CSM patients were associated with greater complexity and costs. In this institutional review board-exempt study, Medicare 1) hip fracture and 2) CSM patients between 2004 and 2014 were identified using the PearlDiver Patient Records Database (PearlDiver Technologies, Inc., CO) with International Classification of Diseases, Ninth Revision, (ICD-9) and Common Procedural Terminology codes. The prevalence of CSM within hip fracture patients was calculated, as was the incidence of hip fractures within CSM patients during this period. Hip fracture patients with CSM were compared with non-CSM hip fracture patients by age, medical comorbidities, average charges/payments, and average lengths of stay (LOS). Hip fracture patients with CSM who underwent cervical surgery were also compared with those who did not undergo cervical surgery, both before and after hip fracture. Statistical analysis with t-test and chi-squared test was performed, with statistical significance set at P < 0.05. Total 22,884 of 2,309,972 hip fracture patients (1.0%) from 2004 to 2014 also had CSM, representing approximately 9900 cases per million persons, higher than previous estimates of the CSM incidence in the general population. These 22,884 hip fracture patients were 4.6% of 496,939 patients with CSM diagnosed during this period, representing a hip fracture incidence of 419 cases per 100,000 persons/year, also higher than previous estimates of hip fracture incidence in the overall population. Hip fracture patients with CSM were significantly younger (P < 0.001) but had significantly greater incidence of hypertension, coronary artery disease, stroke, obesity, tobacco use, diabetes, and osteoporosis (P < 0.001) than non-CSM counterparts, as well as significantly greater average hip fracture-related LOS, per-patient charges, and per-patient payments (P < 0.001). Within this group of hip fractures with CSM, 441 patients (441/22,884; 1.9%) underwent cervical surgery prior to hip fracture, and 245 patients (245/22,884; 1.1%) underwent cervical surgery after hip fracture. These surgically treated patients with CSM were significantly younger but had higher incidence of medical comorbidities (P < 0.001) relative to hip fracture patients with CSM who did not receive cervical surgery at any point. Surgically treated CSM patients also had significantly lower per-patient charges and costs related to their hip fracture care relative to CSM patients with hip fracture who did not receive cervical surgery (P = 0.43, 0.84). This study describes for the first time a high prevalence of CSM in hip fracture patients on a populational level. The 1) prevalence of CSM among hip fracture patients and 2) incidence of hip fractures among CSM patients in this study far exceeded previous epidemiologic estimates. Hip fracture patients with CSM were seen to be significantly younger than hip fracture patients without CSM yet also were seen to have significantly more medical complexity. Hip fracture patients with CSM were also seen to have significantly greater per-patient costs and hip fracture related LOS, findings that are belied by low rates of surgical myelopathy treatment following hip fracture. This study describes for the first time a high prevalence of cervical myelopathy among hip fracture patients on a population level, with implications for both hip fracture prevention and cervical myelopathy diagnosis and treatment.Item Open Access Social risk factors predicting outcomes of cervical myelopathy surgery.(Journal of neurosurgery. Spine, 2022-01) Rethorn, Zachary D; Cook, Chad E; Park, Christine; Somers, Tamara; Mummaneni, Praveen V; Chan, Andrew K; Pennicooke, Brenton H; Bisson, Erica F; Asher, Anthony L; Buchholz, Avery L; Bydon, Mohamad; Alvi, Mohammed Ali; Coric, Domagoj; Foley, Kevin T; Fu, Kai-Ming; Knightly, John J; Meyer, Scott; Park, Paul; Potts, Eric A; Shaffrey, Christopher I; Shaffrey, Mark; Than, Khoi D; Tumialan, Luis; Turner, Jay D; Upadhyaya, Cheerag D; Wang, Michael Y; Gottfried, OrenObjective
Combinations of certain social risk factors of race, sex, education, socioeconomic status (SES), insurance, education, employment, and one's housing situation have been associated with poorer pain and disability outcomes after lumbar spine surgery. To date, an exploration of such factors in patients with cervical spine surgery has not been conducted. The objective of the current work was to 1) define the social risk phenotypes of individuals who have undergone cervical spine surgery for myelopathy and 2) analyze their predictive capacity toward disability, pain, quality of life, and patient satisfaction-based outcomes.Methods
The Cervical Myelopathy Quality Outcomes Database was queried for the period from January 2016 to December 2018. Race/ethnicity, educational attainment, SES, insurance payer, and employment status were modeled into unique social phenotypes using latent class analyses. Proportions of social groups were analyzed for demonstrating a minimal clinically important difference (MCID) of 30% from baseline for disability, neck and arm pain, quality of life, and patient satisfaction at the 3-month and 1-year follow-ups.Results
A total of 730 individuals who had undergone cervical myelopathy surgery were included in the final cohort. Latent class analysis identified 2 subgroups: 1) high risk (non-White race and ethnicity, lower educational attainment, not working, poor insurance, and predominantly lower SES), n = 268, 36.7% (class 1); and 2) low risk (White, employed with good insurance, and higher education and SES), n = 462, 63.3% (class 2). For both 3-month and 1-year outcomes, the high-risk group (class 1) had decreased odds (all p < 0.05) of attaining an MCID score in disability, neck/arm pain, and health-related quality of life. Being in the low-risk group (class 2) resulted in an increased odds of attaining an MCID score in disability, neck/arm pain, and health-related quality of life. Neither group had increased or decreased odds of being satisfied with surgery.Conclusions
Although 2 groups underwent similar surgical approaches, the social phenotype involving non-White race/ethnicity, poor insurance, lower SES, and poor employment did not meet MCIDs for a variety of outcome measures. This finding should prompt surgeons to proactively incorporate socially conscience care pathways within healthcare systems, as well as to optimize community-based resources to improve outcomes and personalize care for populations at social risk.
