Item Open Access Association of Biomarkers with Individual and Multiple Body Sites of Pain: The Johnston County Osteoarthritis Project.(Journal of pain research, 2022-01) Norman, Katherine S; Goode, Adam P; Alvarez, Carolina; Hu, David; George, Steven Z; Schwartz, Todd A; Danyluk, Stephanie T; Fillipo, Rebecca; Kraus, Virginia B; Huebner, Janet L; Cleveland, Rebecca J; Jordan, Joanne M; Nelson, Amanda E; Golightly, Yvonne MIntroduction
Biochemical biomarkers may provide insight into musculoskeletal pain reported at individual or multiple body sites. The purpose of this study was to determine if biomarkers or pressure-pain threshold (PPT) were associated with individual or multiple sites of pain.Methods
This cross-sectional analysis included 689 community-based participants. Self-reported symptoms (ie, pain, aching, or stiffness) were ascertained about the neck, upper back/thoracic, low back, shoulders, elbows, wrist, hands, hips, knees, ankles, and feet. Measured analytes included CXCL-6, RANTES, HA, IL-6, BDNF, OPG and NPY. A standard dolorimeter measured PPT. Logistic regression was used determine the association between biomarkers and PPT with individual and summed sites of pain.Results
Increased IL-6 and HA were associated with knee pain (OR=1.30, 95% CI 1.03, 1.64) and (OR=1.32, 95% CI 1.01, 1.73) respectively; HA was also associated with elbow/wrist/hand pain (OR=1.60, 95% CI 1.22, 2.09). Those with increased NPY levels were less likely to have shoulder pain (OR=0.56, 95% CI 0.33, 0.93). Biomarkers HA (OR=1.50, 95% CI 1.07, 2.10), OPG (OR=1.74, 95% CI 1.00, 3.03), CXCL-6 (OR=1.75, 95% CI 1.02, 3.01) and decreased PPT (OR=3.97, 95% CI 2.22, 7.12) were associated with multiple compared to no sites of pain. Biomarker HA (OR=1.57, 95% CI 1.06, 2.32) and decreased PPT (OR=3.53, 95% CI 1.81, 6.88) were associated with multiple compared to a single site of pain.Conclusion
Biomarkers of inflammation (HA, OPG, IL-6 and CXCL-6), pain (NPY) and PPT may help to understand the etiology of single and multiple pain sites.Item Open Access Comparative analysis of patient-reported outcomes in myelopathy and myeloradiculopathy: a Quality Outcomes Database study.(Journal of neurosurgery. Spine, 2024-09) Porche, Ken; Bisson, Erica F; Sherrod, Brandon; Dru, Alexander; Chan, Andrew K; Shaffrey, Christopher I; Gottfried, Oren N; Bydon, Mohamad; Asher, Anthony L; Coric, Domagoj; Potts, Eric A; Foley, Kevin T; Wang, Michael Y; Fu, Kai-Ming; Virk, Michael S; Knightly, John J; Meyer, Scott; Upadhyaya, Cheerag D; Shaffrey, Mark E; Uribe, Juan S; Tumialán, Luis M; Turner, Jay D; Chou, Dean; Haid, Regis W; Mummaneni, Praveen V; Park, PaulMyelopathy in the cervical spine can present with diverse symptoms, many of which can be debilitating for patients. Patients with radiculopathy symptoms demonstrate added complexity because of the overlapping symptoms and treatment considerations. The authors sought to assess outcomes in patients with myelopathy presenting with or without concurrent radiculopathy. The Quality Outcomes Database, a prospectively collected multi-institutional database, was used to analyze demographic, clinical, and surgical variables of patients presenting with myelopathy or myeloradiculopathy as a result of degenerative pathology. Outcome measures included arm (VAS-arm) and neck (VAS-neck) visual analog scale (VAS) scores, modified Japanese Orthopaedic Association (mJOA) scale score, EuroQol VAS (EQ-VAS) score, and Neck Disability Index (NDI) at 3, 12, and 24 months compared with baseline. A total of 1015 patients were included in the study: 289 patients with myelopathy alone (M0), 239 with myeloradiculopathy but no arm pain (MRAP-), and 487 patients with myeloradiculopathy and arm pain (MRAP+). M0 patients were older than the myeloradiculopathy cohorts combined (M0 64.2 vs MRAP- + MRAP+ 59.5 years, p < 0.001), whereas MRAP+ patients had higher BMI and a greater incidence of current smoking compared with the other cohorts. There were more anterior approaches used in in MRAP+ patients and more posterior approaches used in M0 patients. In severely myelopathic patients (mJOA scale score ≤ 10), posterior approaches were used more often for M0 (p < 0.0001) and MRAP+ (p < 0.0001) patients. Patients with myelopathy and myeloradiculopathy both exhibited significant improvement at 1 and 2 years across all outcome domains. The amount of improvement did not vary based on surgical approach. In comparing cohort outcomes, postoperative outcome differences were associated with patient-reported scores at baseline. Patients with myelopathy and those with myeloradiculopathy demonstrated significant and similar improvement in arm and neck pain scores, myelopathy, disability, and quality of life at 3 months that was sustained at 1- and 2-year follow-up intervals. More radicular symptoms and arm pain increased the likelihood of a surgeon choosing an anterior approach, whereas more severe myelopathy increased the likelihood of approaching posteriorly. Surgical approach itself was not an independent predictor of outcome.Item Open Access Complementary Approaches for Military Women with Chronic Pelvic Pain: A Randomized Trial.(Journal of integrative and complementary medicine, 2022-10) Crisp, Carol D; Baldi, Robert; Fuller, Matthew; Abreu, Eduardo; Nackley, Andrea GIntroduction: Active duty (AD) women suffer with chronic pelvic pain (CPP) while providers tackle diagnoses and treatments to keep them functional without contributing to the opioid epidemic. The purpose of this randomized trial was to determine the effectiveness of noninvasive, self-explanatory mindfulness-based stress reduction (MBSR) or self-paced healthy lifestyle (HL) interventions on CPP in AD women. Methods: A 6-week, interventional prospective study with AD women aged 21-55 years at Mountain Home (MTHM), Idaho, was conducted. Women were randomly assigned to MBSR (N = 21) or HL (N = 20) interventions. The primary outcome was pain perception. The secondary outcomes were depression and circulating cytokine levels. Results: Women in the MBSR group exhibited reduced pain interference (p < 0.01) and depression (p < 0.05) alongside decreased interleukin (IL)-4 (p < 0.05), IL-6 (p < 0.05), eotaxin (p < 0.05), monocyte chemoattractant protein-1 (p = 0.06), and interleukin-1 receptor antagonist (IL-1ra) (p < 0.01) and increased vascular endothelial growth factor (p < 0.05). Women in the HL group did not have changes in pain; however, they did exhibit reduced depression (p < 0.05) alongside decreased granulocyte-macrophage colony-stimulating factor (p < 0.05) and increased tumor necrosis factor alpha (p < 0.05), stromal cell-derived factor-1 (p < 0.01), and IL-1ra (p < 0.01). Conclusions: AD women receiving MBSR or HL had reduced depression scores and altered circulating cytokine levels; however, only those receiving MBSR had reduced pain perception. Findings support MBSR as an effective and viable behavioral treatment for AD women suffering from CPP and provide premise for larger randomized controlled studies. Clinical Trial Registration: MOCHI-An RCT of mindfulness as a treatment for CPP in AD Women NCT04104542 (September 26, 2019).Item Open Access Does the number of social factors affect long-term patient-reported outcomes and satisfaction in those with cervical myelopathy? A QOD study.(Journal of neurosurgery. Spine, 2024-01) Park, Christine; Shaffrey, Christopher I; Than, Khoi D; Bisson, Erica F; Sherrod, Brandon A; Asher, Anthony L; Coric, Domagoj; Potts, Eric A; Foley, Kevin T; Wang, Michael Y; Fu, Kai-Ming; Virk, Michael S; Knightly, John J; Meyer, Scott; Park, Paul; Upadhyaya, Cheerag; Shaffrey, Mark E; Buchholz, Avery L; Tumialán, Luis M; Turner, Jay D; Agarwal, Nitin; Chan, Andrew K; Chou, Dean; Chaudhry, Nauman S; Haid, Regis W; Mummaneni, Praveen V; Michalopoulos, Georgios D; Bydon, Mohamad; Gottfried, Oren NIt is not clear whether there is an additive effect of social factors in keeping patients with cervical spondylotic myelopathy (CSM) from achieving both a minimum clinically important difference (MCID) in outcomes and satisfaction after surgery. The aim of this study was to explore the effect of multiple social factors on postoperative outcomes and satisfaction. This was a multiinstitutional, retrospective study of the prospective Quality Outcomes Database (QOD) CSM cohort, which included patients aged 18 years or older who were diagnosed with primary CSM and underwent operative management. Social factors included race (White vs non-White), education (high school or below vs above), employment (employed vs not), and insurance (private vs nonprivate). Patients were considered to have improved from surgery if the following criteria were met: 1) they reported a score of 1 or 2 on the North American Spine Society index, and 2) they met the MCID in patient-reported outcomes (i.e., visual analog scale [VAS] neck and arm pain, Neck Disability Index [NDI], and EuroQol-5D [EQ-5D]). Of the 1141 patients included in the study, 205 (18.0%) had 0, 347 (30.4%) had 1, 334 (29.3%) had 2, and 255 (22.3%) had 3 social factors. The 24-month follow-up rate was > 80% for all patient-reported outcomes. After adjusting for all relevant covariates (p < 0.02), patients with 1 or more social factors were less likely to improve from surgery in all measured outcomes including VAS neck pain (OR 0.90, 95% CI 0.83-0.99) and arm pain (OR 0.88, 95% CI 0.80-0.96); NDI (OR 0.90, 95% CI 0.83-0.98); and EQ-5D (OR 0.90, 95% CI 0.83-0.97) (all p < 0.05) compared to those without any social factors. Patients with 2 social factors (outcomes: neck pain OR 0.86, arm pain OR 0.81, NDI OR 0.84, EQ-5D OR 0.81; all p < 0.05) or 3 social factors (outcomes: neck pain OR 0.84, arm pain OR 0.84, NDI OR 0.84, EQ-5D OR 0.84; all p < 0.05) were more likely to fare worse in all outcomes compared to those with only 1 social factor. Compared to those without any social factors, patients who had at least 1 social factor were less likely to achieve MCID and feel satisfied after surgery. The effect of social factors is additive in that patients with a higher number of factors are less likely to improve compared to those with only 1 social factor.Item Open Access Economic burden of nonoperative treatment of adult spinal deformity.(J Neurosurg Spine, 2023-12-01) Passias, Peter G; Ahmad, Waleed; Dave, Pooja; Lafage, Renaud; Lafage, Virginie; Mir, Jamshaid; Klineberg, Eric O; Kabeish, Khaled M; Gum, Jeffrey L; Line, Breton G; Hart, Robert; Burton, Douglas; Smith, Justin S; Ames, Christopher P; Shaffrey, Christopher I; Schwab, Frank; Hostin, Richard; Buell, Thomas; Hamilton, D Kojo; Bess, ShayOBJECTIVE: The purpose of this study was to investigate the cost utility of nonoperative treatment for adult spinal deformity (ASD). METHODS: Nonoperatively and operatively treated patients who met database criteria for ASD and in whom complete radiographic and health-related quality of life data at baseline and at 2 years were available were included. A cost analysis was completed on the PearlDiver database assessing the average cost of nonoperative treatment prior to surgical intervention based on previously published treatments (NSAIDs, narcotics, muscle relaxants, epidural steroid injections, physical therapy, and chiropractor). Utility data were calculated using the Oswestry Disability Index (ODI) converted to SF-6D with published conversion methods. Quality-adjusted life years (QALYs) used a 3% discount rate to account for residual decline in life expectancy (78.7 years). Minor and major comorbidities and complications were assessed according to the CMS.gov manual's definitions. Successful nonoperative treatment was defined as a gain in the minimum clinically importance difference (MCID) in both ODI and Scoliosis Research Society (SRS)-pain scores, and failure was defined as a loss in MCID or conversion to operative treatment. Patients with baseline ODI ≤ 20 and continued ODI of ≤ 20 at 2 years were considered nonoperative successful maintenance. The average utilization of nonoperative treatment and cost were applied to the ASD cohort. RESULTS: A total of 824 patients were included (mean age 58.24 years, 81% female, mean body mass index 27.2 kg/m2). Overall, 75.5% of patients were in the operative and 24.5% were in the nonoperative cohort. At baseline patients in the operative cohort were significantly older, had a greater body mass index, increased pelvic tilt, and increased pelvic incidence-lumbar lordosis mismatch (all p < 0.05). With respect to deformity, patients in the operative group had higher rates of severe (i.e., ++) sagittal deformity according to SRS-Schwab modifiers for pelvic tilt, sagittal vertical axis, and pelvic incidence-lumbar lordosis mismatch (p < 0.05). At 2 years, patients in the operative cohort showed significantly increased rates of a gain in MCID for physical component summary of SF-36, ODI, and SRS-activity, SRS-pain, SRS-appearance, and SRS-mental scores. Cost analysis showed the average cost of nonoperative treatment 2 years prior to surgical intervention to be $2041. Overall, at 2 years patients in the nonoperative cohort had again in ODI of 0.36, did not show a gain in QALYs, and nonoperative treatment was determined to be cost-ineffective. However, a subset of patients in this cohort underwent successful maintenance treatment and had a decrease in ODI of 1.1 and a gain in utility of 0.006 at 2 years. If utility gained for this cohort was sustained to full life expectancy, patients' cost per QALY was $18,934 compared to a cost per QALY gained of $70,690.79 for posterior-only and $48,273.49 for combined approach in patients in the operative cohort. CONCLUSIONS: Patients with ASD undergoing operative treatment at baseline had greater sagittal deformity and greater improvement in health-related quality of life postoperatively compared to patients treated nonoperatively. Additionally, patients in the nonoperative cohort overall had an increase in ODI and did not show improvement in utility gained. Patients in the nonoperative cohort who had low disability and sagittal deformity underwent successful maintenance and cost-effective treatment.Item Open Access Evolution of transversus abdominis plane infiltration techniques for postsurgical analgesia following abdominal surgeries.(Local Reg Anesth, 2015) Gadsden, Jeffrey; Ayad, Sabry; Gonzales, Jeffrey J; Mehta, Jaideep; Boublik, Jan; Hutchins, JacobTransversus abdominis plane (TAP) infiltration is a regional anesthesia technique that has been demonstrated to be effective for management of postsurgical pain after abdominal surgery. There are several different clinical variations in the approaches used for achieving analgesia via TAP infiltration, and methods for identification of the TAP have evolved considerably since the landmark-guided technique was first described in 2001. There are many factors that impact the analgesic outcomes following TAP infiltration, and the various nuances of this technique have led to debate regarding procedural classification of TAP infiltration. Based on our current understanding of fascial and neuronal anatomy of the anterior abdominal wall, as well as available evidence from studies assessing local anesthetic spread and cutaneous sensory block following TAP infiltration, it is clear that TAP infiltration techniques are appropriately classified as field blocks. While the objective of peripheral nerve block and TAP infiltration are similar in that both approaches block sensory response in order to achieve analgesia, the technical components of the two procedures are different. Unlike peripheral nerve block, which involves identification or stimulation of a specific nerve or nerve plexus, followed by administration of a local anesthetic in close proximity, TAP infiltration involves administration and spread of local anesthetic within an anatomical plane of the surgical site.Item Open Access Preoperative pain level and patient expectation predict hospital length of stay after total hip arthroplasty.(J Arthroplasty, 2015-04) Halawi, Mohamad J; Vovos, Tyler J; Green, Cindy L; Wellman, Samuel S; Attarian, David E; Bolognesi, Michael PThe purpose of this study was to identify preoperative predictors of length of stay after primary total hip arthroplasty in a patient population reflecting current trends toward shorter hospitalization and using readily obtainable factors that do not require scoring systems. A retrospective review of 112 consecutive patients was performed. High preoperative pain level and patient expectation of discharge to extended care facilities (ECFs) were the only significant multivariable predictors of hospitalization extending beyond 2 days (P=0.001 and P<0.001 respectively). Patient expectation remained significant after adjusting for Medicare's 3-day requirement for discharge to ECFs (P<0.001). The study was adequately powered to analyze the variables in the multivariable logistic regression model, which had a concordance index of 0.857.Item Open Access Sensory neuron-TRPV4 modulates temporomandibular disorder pain via CGRP in mice.(The journal of pain, 2022-12) Suttle, Abbie; Wang, Peng; Dias, Fabiana C; Zhang, Qiaojuan; Luo, Yuhui; Simmons, Lauren; Bortsov, Andrey; Tchivileva, Inna E; Nackley, Andrea G; Chen, YongTemporomandibular disorder (TMD) pain that involves inflammation and injury in the temporomandibular joint (TMJ) and/or masticatory muscle is the most common form of orofacial pain. We recently found that transient receptor potential vanilloid-4 (TRPV4) in trigeminal ganglion (TG) neurons is upregulated after TMJ inflammation, and TRPV4 co-expresses with calcitonin gene-related peptide (CGRP) in TMJ-innervating TG neurons. Here, we extended these findings to determine the specific contribution of TRPV4 in TG neurons to TMD pain, and examine whether sensory neuron-TRPV4 modulates TMD pain via CGRP. In mouse models of TMJ inflammation or masseter muscle injury, sensory neuron-Trpv4 conditional knockout (cKO) mice displayed reduced pain. Co-expression of TRPV4 and CGRP in TMJ- or masseter muscle-innervating TG neurons was increased after TMJ inflammation and masseter muscle injury, respectively. Activation of TRPV4-expressing TG neurons triggered secretion of CGRP, which was associated with increased levels of CGRP in peri-TMJ tissues, masseter muscle, spinal trigeminal nucleus, and plasma in both models. Local injection of CGRP into the TMJ or masseter muscle evoked acute pain in naïve mice, while blockade of CGRP receptor attenuated pain in mouse models of TMD. These results suggest that TRPV4 in TG neurons contributes to TMD pain by potentiating CGRP secretion. Perspective: This study demonstrates that activation of TRPV4 in TG sensory neurons drives pain by potentiating the release of pain mediator CGRP in mouse models of TMJ inflammation and masseter muscle injury. Targeting TRPV4 and CGRP may be of clinical potential in alleviating TMD pain.Item Open Access Spinal cord dorsal horn sensory gate in preclinical models of chemotherapy-induced painful neuropathy and contact dermatitis chronic itch becomes less leaky with Kcc2 gene expression-enhancing treatments.(Frontiers in molecular neuroscience, 2022-01) Yeo, Michele; Zhang, Qiaojuan; Ding, LeAnne; Shen, Xiangjun; Chen, Yong; Liedtke, WolfgangLow intraneuronal chloride in spinal cord dorsal horn (SCDH) pain relay neurons is of critical relevance for physiological transmission of primary sensory afferents because low intraneuronal chloride dictates GABA-ergic and glycin-ergic neurotransmission to be inhibitory. If neuronal chloride rises to unphysiological levels, the primary sensory gate in the spinal cord dorsal horn becomes corrupted, with resulting behavioral hallmarks of hypersensitivity and allodynia, for example in pathological pain. Low chloride in spinal cord dorsal horn neurons relies on the robust gene expression of Kcc2 and sustained transporter function of the KCC2 chloride-extruding electroneutral transporter. Based on a recent report where we characterized the GSK3-inhibitory small molecule, kenpaullone, as a Kcc2 gene expression-enhancer that potently repaired diminished Kcc2 expression and KCC2 transporter function in SCDH pain relay neurons, we extend our recent findings by reporting (i) effective pain control in a preclinical model of taxol-induced painful peripheral neuropathy that was accomplished by topical application of a TRPV4/TRPA1 dual-inhibitory compound (compound 16-8), and was associated with the repair of diminished Kcc2 gene expression in the SCDH; and (ii) potent functioning of kenpaullone as an antipruritic in a DNFB contact dermatitis preclinical model. These observations suggest that effective peripheral treatment of chemotherapy-induced painful peripheral neuropathy impacts the pain-transmitting neural circuit in the SCDH in a beneficial manner by enhancing Kcc2 gene expression, and that chronic pruritus might be relayed in the primary sensory gate of the spinal cord, following similar principles as pathological pain, specifically relating to the critical functioning of Kcc2 gene expression and the KCC2 transporter function.Item Open Access The Effect of Psychiatric History on Pain and Related Outcomes Among Living Kidney Donors.(Progress in transplantation (Aliso Viejo, Calif.), 2021-06) Fox, Kristen R; Gulin, Shaina L; Bruschwein, Heather M; Rose, Terra; Burker, Eileen J; Kozlowski, Tomasz; Loiselle, Marci MIntroduction
Living donor transplantation of kidneys accounts for one quarter of transplants performed in the United States. Careful screening of psychiatric history is a standard part of the donor evaluation. Little is known about the impact of psychiatric history on post-donation course and pain experience.Research question
This study investigated whether psychiatric history was associated with pain and related outcomes among living kidney donors.Design
A retrospective medical record review was conducted of 75 living kidney donors who underwent laparoscopic donor nephrectomy. All donor candidates completed a psychological evaluation and were approved for donation by a multidisciplinary committee. History of psychiatric diagnosis and psychiatric medication use were obtained from donors' psychological evaluation reports. Data on pain and related outcomes (ie, history of prescribed pain medication, post-donation pain, opioid use, length of hospital stay, post-donation emergency department visits), as well as demographic and donation-related characteristics were also abstracted from medical records.Results
Psychiatric history, including current or historical psychiatric diagnosis or psychiatric medication use, in living kidney donors who were evaluated and approved for donation by a transplant psychologist was not associated with greater perceived pain, greater use of opioid pain medication in the post-operative period, longer hospital stays, or more frequent post-donation emergency department visits.Discussion
The findings demonstrate that carefully screened donors with a psychiatric history have comparable pain-related outcomes as donors without a psychiatric history. This study highlights the importance of the pre-donation psychological evaluation in promoting positive postdonation outcomes through careful selection of donor candidates.Item Open Access What predicts the best 24-month outcomes following surgery for cervical spondylotic myelopathy? A QOD prospective registry study(JOURNAL OF NEUROSURGERY-SPINE, 2024) Chan, Andrew K; Park, Christine; Shaffrey, Christopher I; Gottfried, Oren N; Than, Khoi D; Bisson, Erica F; Bydon, Mohamad; Asher, Anthony L; Coric, Domagoj; Potts, Eric A; Foley, Kevin T; Wang, Michael Y; Fu, Kai-Ming; Virk, Michael S; Knightly, John J; Meyer, Scott; Park, Paul; Upadhyaya, Cheerag D; Shaffrey, Mark E; Buchholz, Avery L; Tumialan, Luis M; Turner, Jay D; Michalopoulos, Giorgos; Sherrod, Brandon A; Agarwal, Nitin; Chou, Dean; Haid, Regis W; Mummaneni, Praveen VItem Open Access What predicts the best 24-month outcomes following surgery for cervical spondylotic myelopathy? A QOD prospective registry study.(Journal of neurosurgery. Spine, 2024-01) Chan, Andrew K; Park, Christine; Shaffrey, Christopher I; Gottfried, Oren N; Than, Khoi D; Bisson, Erica F; Bydon, Mohamad; Asher, Anthony L; Coric, Domagoj; Potts, Eric A; Foley, Kevin T; Wang, Michael Y; Fu, Kai-Ming; Virk, Michael S; Knightly, John J; Meyer, Scott; Park, Paul; Upadhyaya, Cheerag D; Shaffrey, Mark E; Buchholz, Avery L; Tumialán, Luis M; Turner, Jay D; Michalopoulos, Giorgos; Sherrod, Brandon A; Agarwal, Nitin; Chou, Dean; Haid, Regis W; Mummaneni, Praveen VThe aim of this study was to identify predictors of the best 24-month improvements in patients undergoing surgery for cervical spondylotic myelopathy (CSM). For this purpose, the authors leveraged a large prospective cohort of surgically treated patients with CSM to identify factors predicting the best outcomes for disability, quality of life, and functional status following surgery. This was a retrospective analysis of prospectively collected data. The Quality Outcomes Database (QOD) CSM dataset (1141 patients) at 14 top enrolling sites was used. Baseline and surgical characteristics were compared for those reporting the top and bottom 20th percentile 24-month Neck Disability Index (NDI), EuroQol-5D (EQ-5D), and modified Japanese Orthopaedic Association (mJOA) change scores. A multivariable logistic model was constructed and included candidate variables reaching p ≤ 0.20 on univariate analyses. Least important variables were removed in a stepwise manner to determine the significant predictors of the best outcomes (top 20th percentile) for 24-month NDI, EQ-5D, and mJOA change. A total of 948 (83.1%) patients with 24-month follow-up were included in this study. For NDI, 204 (17.9%) had the best NDI outcome and 200 (17.5%) had the worst NDI outcome. Factors predicting the best NDI outcomes included symptom duration less than 12 months (OR 1.5, 95% CI 1.1-1.9; p = 0.01); procedure other than posterior fusion (OR 1.5, 95% CI 1.03-2.1; p = 0.03); higher preoperative visual analog scale neck pain score (OR 1.2, 95% CI 1.1-1.3; p < 0.001); and higher baseline NDI (OR 1.06, 95% CI 1.05-1.07; p < 0.001). For EQ-5D, 163 (14.3%) had the best EQ-5D outcome and 169 (14.8%) had the worst EQ-5D outcome. Factors predicting the best EQ-5D outcomes included arm pain-only complaints (compared to neck pain) (OR 1.9, 95% CI 1.3-2.9; p = 0.002) and lower baseline EQ-5D (OR 167.7 per unit lower, 95% CI 85.0-339.4; p < 0.001). For mJOA, 222 (19.5%) had the best mJOA outcome and 238 (20.9%) had the worst mJOA outcome. Factors predicting the best mJOA outcomes included lower BMI (OR 1.03 per unit lower, 95% CI 1.004-1.05; p = 0.02; cutoff value of ≤ 29.5 kg/m2); arm pain-only complaints (compared to neck pain) (OR 1.7, 95% CI 1.1-2.5; p = 0.02); and lower baseline mJOA (OR 1.6 per unit lower, 95% CI 1.5-1.7; p < 0.001). Compared to the worst outcomes for EQ-5D, the best outcomes were associated with patients with arm pain-only complaints. For mJOA, lower BMI and arm pain-only complaints portended the best outcomes. For NDI, those with the best outcomes had shorter symptom durations, higher preoperative neck pain scores, and less often underwent posterior spinal fusions. Given the positive impact of shorter symptom duration on outcomes, these data suggest that early surgery may be beneficial for patients with CSM.
