Abstract
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.

Impact of preoperative back pain severity on PROMIS outcomes following minimally invasive lumbar decompression. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2024:10.1007/s00586-024-08275-w. [PMID: 39133294 DOI: 10.1007/s00586-024-08275-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 03/28/2024] [Accepted: 04/15/2024] [Indexed: 08/13/2024]
Abstract
PURPOSE To evaluate the effect of baseline back pain severity on PROMIS mental health outcomes following minimally invasive lumbar decompression (LD). METHODS Patients undergoing elective, primary, single-level LD were retrospectively reviewed from a prospective single spine surgeon registry. Perioperative characteristics, demographics, and the following patient-reported outcomes (PROs) were extracted: Oswestry Disability Index (ODI)/Patient-Health Questionnaire-9 /PROMIS-Physical Function/Anxiety/Pain Interference/Sleep Disturbance (PROMIS-PF/A/PI/SD). Two cohorts were created: preoperative VAS-B < 7 and VAS-B ≥ 7. Change in PROs (ΔPROs) from baseline to six weeks/final follow-up were determined. Average patient follow-up was 13.4 ± 8.8 months. Minimal clinically important difference (MCID) achievement rates were calculated and compared through multivariable logistic regression. Postoperative scores and ΔPROs, were compared with multivariable linear regression while all other data was compared between groups with inferential statistics. RESULTS Altogether, 347 patients were included, with 190 in the VAS-B < 7 group. VAS-B ≥ 7 reported worse outcomes preoperatively (p ≤ 0.013, all). At six weeks, VAS-B ≥ 7 reported worse VAS-B (p = 0.017), with no other significant differences. At final follow-up, patients with worse VAS-B reported worse ODI (p = 0.040) and VAS-B while all other PROs were similar (p ≥ 0.078, all). VAS-B ≥ 7 experienced greater 6-week improvements in VAS-B/ODI/PROMIS-PI/PROMIS-SD (p ≤ 0.009, all), greater VAS-B/ODI/PROMIS-SD improvement by final follow-up (p ≤ 0.009, all) and greater MCID achievement in ODI/VAS-B (p ≤ 0.027). CONCLUSION Patients with worse baseline back pain report inferior baseline scores that converge with those with milder preoperative back pain by 6 weeks after LD and reported greater 6-week improvements in disability, pain interference, and sleep disturbance by 6 weeks, and greater improvements in disability and sleep disturbance by final follow-up.

Abstract
The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum (high p_{T}) hadron trigger in proton-proton and central Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV. A data-driven statistical method is used to mitigate the large uncorrelated background in central Pb-Pb collisions. Recoil jet distributions are reported for jet resolution parameter R=0.2, 0.4, and 0.5 in the range 7

Abstract
STUDY DESIGN This is a retrospective review. OBJECTIVE To examine the effect of preoperative motor weakness on clinical outcomes in patients undergoing cervical disk replacement (CDR). SUMMARY OF BACKGROUND DATA Studies examining the effect of preoperative motor weakness on postoperative clinical outcomes in CDR are limited. METHODS Patient cohorts were based on documented upper-extremity motor weakness on physical exam versus no motor weakness. Demographics, perioperative characteristics, and preoperative patient-reported outcome measures (PROMs) were compared using univariate inferential statistics. PROMs consisted of Visual Analog Pain Scale-Neck (VAS-N), Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), VAS-Arm (VAS-A), 12-Item Short Form (SF-12) Physical Component Score (PCS), Oswestry Neck Disability Index (NDI), and SF-12 Mental Component Score (MCS). Postoperative PROMs were collected at the 6-week, 12-week, 6-month, and final follow-up up to 1-yeartime points, and intercohort minimum clinically important difference (MCID) achievement was compared through multivariable linear logistic regression adjusting for significant differences in preoperative characteristics. RESULTS A total of 118 patients formed cohorts based on documented upper-extremity weakness (n=73) versus no weakness (n=45). The average time to postoperative follow-up was 9.7±7.0 mo. The differences in insurance type between the 2 cohorts were significant (P<0.042). Perioperative diagnosis of foraminal stenosis was significantly more common in the motor weakness cohort (P<0.013). There were no differences in reported PROMs between cohorts. Patients with motor weakness reported significant MCID achievement for PROMIS-PF at 6-/12-weeks (P<0.012, P<0.041 respectively), SF-12 PCS at 6-months (P<0.042), VAS-N at final follow-up (P<0.021), and NDI at final follow-up (P<0.013). CONCLUSIONS CDR patients with preoperative muscle weakness achieved MCID across several PROMs compared with patients without muscle weakness. Patients with motor weakness reported greater improvement in mental health, pain, and disability as early as 6 weeks and up to 1 year after CDR. This information serves to inform physicians that motor weakness may not indicate a negative overall outcome.

Obesity Does Not Negatively Affect Patient-perceived Outcomes After Cervical Disc Replacement for Disc Herniation. Clin Spine Surg 2024; 37:270-274. [PMID: 38245814 DOI: 10.1097/bsd.0000000000001562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Accepted: 11/29/2023] [Indexed: 01/22/2024]
Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To assess the impact of Body Mass Index (BMI) on patient-reported outcome measures (PROMs) after cervical disc replacement (CDR). BACKGROUND BMI may affect PROMs after spine surgery. METHODS Primary CDR recipients for herniated disc(s) with BMI <40 were retrospectively selected from a single-surgeon registry. Cohorts were divided into non-obese (BMI <30) and obese (BMI ≥30). Intercohort in-hospital complication rates were compared through independent samples t tests. Pre/postoperative PROMs were compared between cohorts through multivariable regression accounting for demographic differences. Final follow-up dates between patients averaged 11.8 ± 9.3 months. PROMs assessed included Patient-reported Outcomes Measurement Information System-Physical Function, Neck Disability Index, Visual Analog Scale-Neck, Visual Analog Scale-Arm, and the 9-item Patient Health Questionnaire. Improvements in PROMs were evaluated and compared at each follow-up within cohorts through paired t tests. The magnitude of improvement in PROMs from preoperative baseline at 6-week follow-up (∆PROM-6W) and final follow-up (∆PROM-FF) along with achievement rates of minimum clinically important differences were compared between cohorts through multivariable regression accounting for demographic differences. RESULTS Of 153 patients, 53 patients were noted as obese. Demographic differences included age, prevalence of hypertension and diabetes, and comorbidity burden scores ( P ≤ 0.011, all). No significant variations in in-hospital complications were found. The non-obese cohort demonstrated improvements in all PROMs at 6 weeks and final follow-up periods ( P ≤ 0.005, all). The obese cohort demonstrated improvements in all postoperative PROMs besides 9-item Patient Health Questionnaire at 6 weeks ( P ≤ 0.015, all). After accounting for age and comorbidity variations, there were no significant intercohort differences in raw PROM scores, ∆PROM-6W, ∆PROM-FF, or minimum clinically important difference achievement rates. CONCLUSIONS Regardless of BMI, patients experience significant improvements in physical function, disability, pain, and mental health after CDR for disc herniation. Patients with obesity do not suffer inferior patient-perceived outcomes after CDR. These findings may help surgeons counsel patients in the preoperative period.

Impact of Preoperative Symptom Duration on Patient-reported Outcomes After Minimally Invasive Transforaminal Interbody Fusion for Degenerative Spondylolisthesis. Clin Spine Surg 2024; 37:E239-E244. [PMID: 38245808 DOI: 10.1097/bsd.0000000000001560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 11/29/2023] [Indexed: 01/22/2024]
Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To assess the impact of preoperative symptom duration (PSD) on patient-reported outcome measures (PROMs) after minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for degenerative spondylolisthesis (DSpond). BACKGROUND A prolonged duration of preoperative symptoms may implicate inferior long-term outcomes postsurgery. Prior studies of lumbar fusion recipients are limited by the inclusion of heterogeneous populations. METHODS A single-surgeon registry was retrospectively queried for privately insured patients who had undergone primary, elective, single-level MIS-TLIF for DSpond with a recorded symptom start date. Cohorts were formed by PSD: shorter duration (PSD <1 y) or greater duration (GD; PSD ≥1 y). PROMs evaluated included Patient-reported Outcomes Measurement Information System-Physical Function, Oswestry Disability Index, Visual Analog Scale-Back, Visual Analog Scale-Leg, and 9-item Patient Health Questionnaire. The magnitude of PROM (∆PROM) improvement from preoperative baseline to 6 weeks and final follow-up (∆PROM-FF) were compared between cohorts. Intercohort achievement rates of a minimum clinically important difference in each PROM were compared. RESULTS A total of 133 patients included 85 patients with GD cohort. There were no significant differences in pre hoc demographics and perioperative characteristics between cohorts, as well as preoperative, 6-week, or final follow-up PROMs between cohorts. Both cohorts demonstrated significant improvement in all PROMs at 6 weeks and final follow-up ( P ≤ 0.049, all). There were no significant intercohort differences demonstrated in minimum clinically important difference achievement rates, ∆PROM-6W, or ∆PROM-FF in any PROM. CONCLUSIONS Regardless of the symptom duration before MIS-TLIF for DSpond, patients demonstrate significant improvement in physical function, pain, disability, and mental health. Patients with a GD of preoperative symptoms did not report inferior scores in any PROM domain. Patients with a GD of preoperative symptoms did not suffer inferior rates of clinically meaningful improvement after surgical intervention. These findings should be considered when counseling patients before surgical intervention for DSpond.

Worse Preoperative 12-Item Veterans Rand Physical Component Scores Prognosticate Inferior Outcomes Following Outpatient Lumbar Decompression. Clin Spine Surg 2024:01933606-990000000-00329. [PMID: 38940436 DOI: 10.1097/bsd.0000000000001602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 01/22/2024] [Indexed: 06/29/2024]
Abstract
STUDY DESIGN Retrospective Review. OBJECTIVE Evaluate the influence of the 12-Item veterans Rand (VR-12) physical component score (PCS) on patient-reported outcome measures (PROMs) in an outpatient lumbar decompression (LD) cohort. SUMMARY OF BACKGROUND DATA The influence of baseline VR-12 PCS on postoperative clinical outcomes has not been evaluated in patients undergoing outpatient LD. METHODS Patients undergoing primary, elective, 1/2-level outpatient LD with baseline VR-12 PCS scores were retrospectively identified from a prospectively maintained single-surgeon database. Cohorts were preoperative VR-12 PCS<30 and VR-12 PCS≥30. Patient/perioperative characteristics and preoperative/postoperative 6-week/final follow-up (FF) PROMs were collected. Physical health PROMs included the VR-12 PCS, 12-Item Short Form (SF-12) PCS, patient-reported outcome measure information system-physical function (PROMIS-PF), visual analog scale (VAS)-back/leg, and Oswestry disability index (ODI). Mental health PROMs included the VR-12/SF-12 mental component score (MCS) and the patient-health questionnaire-9 (PHQ-9). Average FF was 13.8±8.9 months postoperatively. PROM improvements at 6 weeks/FF and minimal clinically important difference (MCID) achievement rates were determined. χ2 analysis and the Student's t tests compared demographics, perioperative data, and preoperative PROMs. Multivariate linear/logistic regression compared postoperative PROMs, PROM improvements, and MCID achievement rates. RESULTS Six weeks postoperatively, VR-12 PCS<30 reported worse baseline PROMs (P≤0.042, all) and worse scores except VR-12/SF-12 MCS (P≤0.043, all). Compared with VR-12 PCS≥30, VR-12 PCS<30 had worse FF VR-12 PCS, SF-12 PCS/MCS, PROMIS-PF, PHQ-9, and VAS-Back (P≤0.033, all). VR-12 PCS<30 experienced greater 6-week improvements in VR-12/SF-12 PCS, PHQ-9, VAS-Back, and ODI (P≤0.039, all). VR-12 PCS<30 had greater FF improvements in VR-12/SF-12 PCS, PHQ-9, and ODI (P≤0.001, all) and greater overall MCID achievement in VR-12 PCS/MCS, SF-12 PCS, PHQ-9, and ODI (P≤0.033, all). CONCLUSIONS VR-12 PCS<30 patients-reported worse baseline/postoperative mental/physical health scores. However, they reported greater improvements in physical function, depressive burden, back pain, and disability by 6 weeks and FF and experienced greater MCID achievement for physical functioning, mental health, and disability scores.

Abstract
STUDY DESIGN Retrospective Review. OBJECTIVE To assess the impact of preoperative pain and disability on patient-reported outcome measures (PROMs) following minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for degenerative spondylolisthesis. SUMMARY OF BACKGROUND DATA Varying preoperative symptom severity in lumbar fusion patients alters perceptions of surgical success. METHODS Degenerative spondylolisthesis patients undergoing elective, primary, single-level MI-TLIF were stratified by preoperative symptom severity: Mild (VAS-B<7/ODI<50), Moderate (VAS-B≥7/ODI<50 or VAS-B<7/ODI≥50), and Severe (VAS-B≥7/ODI≥50). PROMs, Patient-reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), ODI, VAS-B, VAS-Leg (VAS-L), and 9-item Patient Health Questionnaire (PHQ-9) were compared at baseline, 6 weeks, and final follow-up (μ=16.3±8.8 mo). Postoperative PROMs, magnitudes of improvement, and minimal clinically important difference (MCID) achievement rates were compared between cohorts through multivariable regression. RESULTS A total of 177 patients were included. Acute postoperative pain and narcotic consumption were highest in the severe cohort (P≤0.003). All preoperative PROMs worsened from mild to severe cohorts (P<0.001). All PROMs continued to be significantly different between cohorts at 6 weeks and final follow-up, with the worst scores in the Severe cohort (P≤0.003). At 6 weeks, all cohorts improved in ODI, VAS-B, VAS-L, and PHQ-9 (P≤0.003), with the Moderate cohort also improving in PROMIS-PF (P=0.017). All Cohorts improved across PROMs at the final follow-up (P≤0.044). Magnitudes of improvement in ODI, VAS-B, and PHQ-9 increased with worsening preoperative symptom severity (P≤0.042). The Moderate and Severe cohorts demonstrated higher MCID achievement in ODI, VAS-B, and PHQ-9 rates than the Mild cohort. CONCLUSIONS Despite preoperative pain and disability severity, patients undergoing MI-TLIF for degenerative spondylolisthesis report significant improvement in physical function, pain, disability, and mental health postoperatively. Patients with increasing symptom severity continued to report worse severity postoperatively compared with those with milder symptoms preoperatively but were more likely to report larger improvements and achieve clinically meaningful improvement in disability, pain, and mental health.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To evaluate mental health influence on minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) patients. SUMMARY OF BACKGROUND DATA Poor mental health has been postulated to indicate inferior patient perceptions of surgical outcomes in spine literature. Few studies have assessed mental health as a dynamic metric throughout the perioperative period. METHODS A single-surgeon database was retrospectively searched for patients who underwent primary, elective MIS-TLIF for degenerative or isthmic spondylolisthesis. Summative depressive burden (SDB) was defined by the sum of preoperative and 6-week postoperative 9-item Patient Health Questionnaire (PHQ-9), with Lesser Burden (LB, SDB<10) and Greater Burden (GB, SDB≥10) cohorts. Patient-reported outcomes measures (PROMs) were compared preoperatively, at 6 weeks, and at final postoperative follow-up (11.4±10.9 mo), using Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), Oswestry disability index (ODI), visual analog scale-back (VAS-B), VAS-leg (VAS-L), and PHQ-9. Improvements at 6-week (∆PROM-6W), final follow-up (∆PROM-FF), and minimum clinically important difference (MCID) achievement were compared. RESULTS The GB cohort consisted of 44 of 105 patients. Demographic variations included older age, higher Charlson comorbidity index, increased hypertension prevalence, and private insurance in the LB cohort (P≤0.018). The LB cohort demonstrated better baseline and 6-week PROMIS-PF/ODI/VAS-L (P≤0.032) and better final PROMIS-PF/ODI/VAS-L/PHQ-9 (P≤0.031). Both cohorts improved in all PROMs at 6 weeks and final follow-up (P≤0.029), except for PROMIS-PF at 6 weeks in the GB cohort. ∆PROM-6W, ∆PROM-FF, and MCID achievement rate for PHQ-9 were greater in the GB cohort (P≤0.001). CONCLUSION On average, patients undergoing MIS-TLIF for degenerative or isthmic spondylolisthesis improved in all PROMs by final follow-up. Patients with GB suffered inferior perceptions of physical function, disability, and leg pain. MCID rates in mental health were higher for GB cohort. Surgeons are encouraged to adopt a compassionate understanding of depressive burden and educate the patient on possible consequential postoperative outcomes.

Cervical Disk Replacement Versus Anterior Cervical Diskectomy and Fusion: Effect of Procedural Variant on Patients With a Prolonged Preoperative Duration of Symptoms From Disk Herniation. J Am Acad Orthop Surg 2024; 32:558-562. [PMID: 38696821 DOI: 10.5435/jaaos-d-23-00655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 02/17/2024] [Indexed: 05/04/2024] Open
Abstract
INTRODUCTION Patients with a prolonged preoperative symptom duration (PSD) in the setting of cervical disk herniation (DH) may suffer inferior outcomes after surgical intervention. Comparison between anterior cervical diskectomy and fusion (ACDF) versus cervical disk arthroplasty (CDA) in this at-risk population has not yet been conducted. METHODS Patients undergoing ACDF or CDA for DH with a PSD > 180 days were selected. Six-week (6W) and final follow-up (FF) patient-reported outcome measures (PROMs) as well as magnitude of postoperative improvements (∆PROM) were compared between cohorts using multivariable linear regression. Intercohort achievement rates of minimal clinically important difference (MCID) in each PROM were compared. RESULTS Seventy-seven of 190 patients were in the CDA cohort. 6W Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF) was superior in the CDA cohort. The ACDF cohort demonstrated notable improvements in the 6W Neck Disability Index (NDI), visual analog scale-neck pain (VAS-N), visual analog scale-arm pain (VAS-A), and 9-item Patient Health Questionnaire (PHQ-9). The CDA cohort demonstrated notable improvements in 6W PROMIS-PF, NDI, VAS-N, and VAS-A. FF VAS-A was better in the CDA cohort. The ACDF cohort demonstrated notable improvements in FF PROMIS-PF, NDI, VAS-N, and VAS-A. The CDA cohort demonstrated notable improvements in all FF PROMs. ∆PROM-6W in PROMIS-PF was greater in the CDA cohort. CONCLUSION Patients with prolonged PSD due to cervical DH demonstrated notable improvements in physical function, disability, pain, and mental health regardless of fusion versus arthroplasty techniques. Accounting for demographic variations, patients undergoing CDA demonstrated a greater magnitude of improvement and superior scores in physical function at the first postoperative follow-up. Rates of clinically tangible improvements in PROMs did not markedly vary by surgical procedure. Patients undergoing CDA may perceive greater early improvements to physical function compared with patients undergoing ACDF for prolonged PSD due to DH.

Does Baseline Facet Arthropathy Influence Early Clinical and Radiographic Outcomes After Cervical Disc Replacement? Neurosurgery 2024:00006123-990000000-01203. [PMID: 38861645 DOI: 10.1227/neu.0000000000003029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 04/18/2024] [Indexed: 06/13/2024] Open
Abstract
BACKGROUND AND OBJECTIVES Severe facet arthropathy is generally a contraindication to undergoing cervical disc replacement (CDR) due to associated instability and potentially limited improvement in neck pain caused by arthropathy. This study evaluates the influence of facet arthropathy on radiographic/early clinical outcomes after CDR. METHODS One/two-level CDR patients from a single surgeon's prospectively maintained database created 2 cohorts based on facet arthropathy: grade 0-1 or 2-3 (milder/moderate arthropathy). Patient-reported outcome measures for neck disability, neck/arm pain, depressive burden, mental/physical health/function were obtained preoperatively and through final follow-up (average follow-up: 8.5 ± 6.5 months). Preoperative/postoperative radiographs measured segmental lordosis and C2-C7/segmental range of motion (ROM) and determined facet grade for each operative level. Demographic differences, perioperative variables, baseline patient-reported outcomes, and intercohort differences/changes for postoperative patient-reported/radiographic outcomes were determined. RESULTS Of 161 patients, 100 were in the milder arthropathy group. There were no differences in baseline patient-reported outcomes. Patients with moderate arthropathy reported superior 6-week 12-Item Veterans Rand Mental/Physical Composite Scores (P ≤ .047, all). By final follow-up, moderate patients reported better 12-Item Veterans Rand Mental/Physical Composite Scores/Patient-Reported Outcome Measurement Information System-Physical Function/Patient-Health Questionnaire-9 (P ≤ .049, all). Cohorts reported similar improvements in all patient-reported outcomes by 6 weeks/final follow-up. Those with more severe facet arthropathy had significantly shorter preoperative disc heights (P < .001). Accounting for baseline disc height differences, by final follow-up, moderate patients had lower segmental ROM (P = .036). There were no significant differences in radiographic measurement changes (P ≥ .264, all). CONCLUSION Postoperatively, patients with moderate facet arthropathy reported lower depressive burden, better mental health/physical function, and lower segmental ROM. However, this did not translate to inferior short-term clinical outcomes. Further study should be conducted on the relationship between clinical/radiographic outcomes in CDR patients with facet arthropathy.

Abstract
This paper reports the effect of incorporation of Yb3+ions on the frequency downconversion luminescence and thermal properties of triply ionised Ho3+doped zinc tellurite (TZ) glasses. The photoluminescence spectra of both the Ho3+/Yb3+doped and codoped glasses have been recorded and observed a green emission band corresponding to the5F4,5S2→5I8(∼550 nm) transition upon various excitations. In the downconversion (DC) emission process, the back energy transfer (BET) mechanism from Ho3+ions to Yb3+ions has also been explored. The colour emitted in the downconversion process is found to be non-tunable at different excitations. Thus, the Ho3+:TZ glass can be utilised for non-colour tunable optical devices under various UV excitations. Also the glass transition (Tg) and crystallisation (Tc) temperatures have been measured for both the doped and codoped glasses and found to be increased in the codoped glass. The singly Ho3+ions doped TZ glass shows better optical downconversion and glass forming ability.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To determine postoperative clinical outcomes in patients undergoing minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for isthmic spondylolisthesis (IS). BACKGROUND Few studies have examined the postoperative clinical trajectory in patients undergoing MIS-TLIF specifically for IS. METHODS Patients were separated into two cohorts based on the previously defined Visual Analog Scale (VAS) back pain (BP) for severe pain: VAS-BP <7 and VAS-BP ≥7. Patient-reported outcome measures (PROMs) of Patient-Reported Outcomes Measurement Information System-physical function (PF), 12-item Short Form (SF-12) Physical/Mental Component Score, Patient Health Questionnaire-9, VAS-BP, VAS leg pain, and Oswestry Disability Index were collected preoperatively and up to 2-year postoperatively. Minimum clinically important difference (MCID) was calculated through previously defined thresholds. RESULTS A total of 160 patients were recorded, with 58 patients in the VAS-BP <7 cohort. The VAS-BP <7 cohort demonstrated significant improvement in all PROMs at one or more postoperative time points. The VAS-BP ≥7 demonstrated significant improvement at 3 or more postoperative time points in all PROMs except for SF-12 Mental Component Score. The VAS-BP <7 cohort reported significantly superior preoperative and postoperative PROMs in all domains, except for SF-12 Physical Component Score. The VAS-BP ≥7 cohort had higher MCID achievement rates at one or more time points in multiple PROMs. CONCLUSION Patients undergoing MIS-TLIF for IS demonstrated significant postoperative improvement in PF, mental function, pain, and disability outcomes independent of preoperative severity of BP. Patients with lower preoperative BP demonstrated superior outcomes in PF, mental function, pain, and disability. However, patients with greater preoperative BP achieved higher rates of MCID in mental function, BP, and disability outcomes. Patients with greater severity of preoperative BP undergoing MIS-TLIF for IS may experience greater rates of clinically relevant improvement in mental function, BP, and disability outcomes.

Abstract
No study has examined the prognostic value of the Veterans RAND-12 (VR-12) Mental Component Score (MCS) on postoperative outcomes in minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) patients. This study examines the effect of preoperative VR-12 MCS on postoperative patient-reported outcome measures (PROMs) in MIS-TLIF patients. Patients were separated into 2 cohorts: VR-12 MCS < 50 and VR-12 MCS ≥ 50. PROMs of VR-12 MCS/Physical Component Score (PCS), Short Form-12 (SF-12) MCS/PCS, Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Back/Leg Pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected.Of 329 patients, 151 were in the VR-12 MCS < 50 cohort. The VR-12 MCS < 50 cohort reported significantly inferior scores in all PROMs preoperatively, significantly inferior VR-12 MCS, SF-12 MCS, PROMIS-PF, PHQ-9, and ODI scores at 6-weeks postoperatively, and significantly inferior scores in all PROMs, except for VAS-BP at final follow-up. Magnitude of 6-week postoperative improvement was significantly greater in the VR-12 MCS < 50 cohort for VR-12 MCS, SF-12 MCS, and PHQ-9. Magnitude of final postoperative improvement was significantly greater in the VR-12 MCS < 50 cohort for VR-12 MCS, SF-12 MCS/PCS, and PHQ-9. MCID achievement rates were significantly greater in the VR-12 MCS < 50 cohort for VR-12 MCS, SF-12 MCS, and PHQ-9. MIS-TLIF patients with lesser preoperative VR-12 MCS reported inferior postoperative outcomes in mental health, physical function, pain, and disability. However, patients with inferior preoperative mental health reported greater rates of clinically meaningful improvement in mental health. Inferior preoperative mental health does not limit postoperative improvement in patients undergoing MIS-TLIF.

Preoperative motor weakness and the impact on patient reported outcomes in lateral lumbar interbody fusion. J Clin Neurosci 2024; 125:7-11. [PMID: 38733901 DOI: 10.1016/j.jocn.2024.04.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 04/26/2024] [Accepted: 04/30/2024] [Indexed: 05/13/2024]
Abstract
This study measures the impact of preoperative motor weakness (MW) on Patient-Reported Outcome Measures (PROMs) in lateral lumbar interbody fusion (LLIF) patients. Retrospectively-sourced data from a prospectively-maintained, single-surgeon database created two cohorts of LLIF patients: patients with/without documented MW. Demographics/perioperative characteristics/PROMs were collected preoperatively and at six-weeks/final follow-up (FF). Studied outcomes were Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), 12-Item Short Form (SF-12) Physical/Mental Component Score (PCS/MCS), Patient Health Questionnaire (PHQ-9), Visual Analog Scale Back/Leg Pain (VAS-BP/LP), and Oswestry Disability Index (ODI). Multivariable linear/logistic regression calculated/compared intercohort minimum clinically important difference (MCID). Mean postoperative follow-up time was 11.5 ± 7.52 months. In total, 214 LLIF patients from December 2010 to May 2023 were included, with 149 having documented MW. In Table 1, self-reported gender was significant between cohorts (p < 0.025). Other significant demographic characteristics were smoker status (p < 0.002), diabetes (p < 0.016), and CCI score (p < 0.011). Table 2 shows notably significant perioperative characteristics: spinal pathology (degenerative spondylolisthesis/foraminal stenosis/herniated nucleus pulposus) (p < 0.005, all), estimated blood loss/length of stay/postoperative day (POD)-zero narcotic consumption (p < 0.001, all). Table 3 outcomes/MCID achievement percentages demonstrated insignificant intercohort differences besides a weakly significant FF ODI score (p < 0.036). MW, a frequently reported symptom in spine surgery, is poorly studied in LLIF patients. Thus, this study evaluates MW impact on PROMs and notes no significant differences. However, one exception regarding FF disability scores was recorded. MW did not affect MCID achievement for our patient population. Therefore, the preliminary findings suggest preoperative MW imparts minimal influence on PROMs/MCID in LLIF patients.

Do Six-Week Postoperative Patient-Reported Outcomes Predict Long-Term Clinical Outcomes Following Lumbar Decompression? World Neurosurg 2024; 185:e900-e906. [PMID: 38458252 DOI: 10.1016/j.wneu.2024.02.149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 02/27/2024] [Accepted: 02/28/2024] [Indexed: 03/10/2024]
Abstract
BACKGROUND Little research has been done to evaluate the prognostic value of short-term postoperative patient-reported outcomes (PROs) on long-term PROs following lumbar decompression (LD). We evaluated the prognostic value of short-term PROs on long-term PROs through 2 years after LD. METHODS A single spine surgeon database was retrospectively queried for patients undergoing primary LD with 6-week postoperative PROs reported. The demographics, perioperative traits, and preoperative, 6-month, 1-year, and 2-year PROs were recorded. The PROs included the visual analog scale (VAS) for back pain, VAS for leg pain, PRO measure information system for physical function (PROMIS-PF), and Oswestry disability index. Two-step multivariate linear regression was performed to determine the predictive value of 6-week PROs for the 6-month, 1-year, and 2-year PROs. RESULTS A total of 277 patients were included. The 6-week Oswestry disability index, VAS for leg pain, and 9-item patient health questionnaire (PHQ-9) are all positive predictors for their respective outcomes at 6 months. Additionally, the 6-week PROMIS-PF was a negative predictor of the 6-month PHQ-9. The 6-week PROMIS-PF positively predicted the PROMIS-PF through 1 year, and the PHQ-9 was a positive predictor of the PHQ-9 at 1 and 2 years postoperatively. CONCLUSIONS The 6-week postoperative PROs are predictive of the same outcomes at 6 months, the PROMIS-PF is predictive through 1 year, and the PHQ-9 is predictive through 2 years. Determining the predictive value of early postoperative PROs can be helpful in understanding the likely postoperative trajectory following LD and informing patient expectations.

[PMID: 38728735 DOI: 10.1103/physrevlett.132.172302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 02/22/2024] [Accepted: 03/22/2024] [Indexed: 05/12/2024]
Abstract
This Letter presents the measurement of near-side associated per-trigger yields, denoted ridge yields, from the analysis of angular correlations of charged hadrons in proton-proton collisions at sqrt[s]=13 TeV. Long-range ridge yields are extracted for pairs of charged particles with a pseudorapidity difference of 1.4<|Δη|<1.8 and a transverse momentum of 1

First Measurement of the |t| Dependence of Incoherent J/ψ Photonuclear Production. PHYSICAL REVIEW LETTERS 2024; 132:162302. [PMID: 38701458 DOI: 10.1103/physrevlett.132.162302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 11/22/2023] [Accepted: 01/23/2024] [Indexed: 05/05/2024]
Abstract
The first measurement of the cross section for incoherent photonuclear production of J/ψ vector mesons as a function of the Mandelstam |t| variable is presented. The measurement was carried out with the ALICE detector at midrapidity, |y|<0.8, using ultraperipheral collisions of Pb nuclei at a center-of-mass energy per nucleon pair of sqrt[s_{NN}]=5.02 TeV. This rapidity interval corresponds to a Bjorken-x range (0.3-1.4)×10^{-3}. Cross sections are given in five |t| intervals in the range 0.04<|t|<1 GeV^{2} and compared to the predictions by different models. Models that ignore quantum fluctuations of the gluon density in the colliding hadron predict a |t| dependence of the cross section much steeper than in data. The inclusion of such fluctuations in the same models provides a better description of the data.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To examine the effect of baseline Veterans RAND-12 (VR-12) Mental Composite Score (MCS) on clinical outcomes in patients undergoing cervical disk replacement (CDR) for herniated disk. BACKGROUND Few studies in spine surgery have evaluated the impact of preoperative VR-12 MCS on postoperative outcomes in patients undergoing CDR. METHODS Patients undergoing CDR for herniated disk were separated into 2 cohorts based on the VR-12 MCS standardized mean: VR-12 MCS<50 (worse mental health) and VR-12 MCS≥50 (better mental health). Patient-reported outcome measures of VR-12 MCS, VR-12 Physical Composite Score, Short Form-12 (SF-12) MCS, SF-12 Physical Composite Score, Patient-Reported Outcomes Measurement Information System Physical Function, Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Neck Pain, VAS Arm Pain, and Neck Disability Index were collected at preoperative and up to 2-year postoperative time points. RESULTS In all, 109 patients were identified, with 50 patients in the worse mental health cohort. The worse mental health cohort reported inferior patient-reported outcome measures in all domains at preoperative, 6-week postoperative, and final postoperative time points. For 6-week postoperative improvement, the worse mental health cohort reported greater improvement for VR-12 MCS, SF-12 MCS, and PHQ-9. For final postoperative improvement, the worse mental health cohort reported greater improvement in VR-12 MCS and SF-12 MCS. Minimum clinically important difference achievement rates were higher in the worse mental health cohort for VR-12 MCS, SF-12 MCS, and PHQ-9. CONCLUSION Patients undergoing cervical disk replacement for herniated disk with worse baseline mental health reported inferior clinical outcomes in mental health, physical function, pain, and disability outcomes throughout the postoperative period. Patients with worse baseline mental health demonstrated greater clinically meaningful improvement in mental health. In cervical disk replacement patients, those with worse baseline mental health may report inferior postoperative clinical outcomes but experience greater rates of tangible improvement in mental health.

The influence of preoperative Veterans RAND-12 physical composite score in patients undergoing anterior lumbar interbody fusion [Retrospective Review]. J Clin Neurosci 2024; 123:36-40. [PMID: 38522109 DOI: 10.1016/j.jocn.2024.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 02/19/2024] [Accepted: 03/18/2024] [Indexed: 03/26/2024]
Abstract
No study has evaluated the preoperative impact of Veterans RAND-12 Physical Composite Score (VR-12 PCS) on anterior lumbar interbody fusion (ALIF) patients. This study examines its influence on physical function, mental health, pain, and disability outcomes. Two cohorts of ALIF patients with preoperative VR-12 PCS scores were formed using a single-surgeon registry: VR-12 PCS < 30 and VR-12 PCS ≥ 30. Demographics, perioperative characteristics, and patient-reported outcome measures (PROMs) were collected. PROMs of VR-12 PCS/Mental Composite Score (MCS), Short Form-12 (SF-12) PCS/MCS, Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale-Back/Leg Pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected pre/postoperatively up to 2-years. Demographics, perioperative characteristics, and preoperative PROMs were compared. Intercohort postoperative 6-week/final PROMs and improvements were compared. Of 80 patients, there were 41 in the VR-12 PCS < 30 cohort. Besides VR-12 PCS, VR-12 PCS < 30 patients reported inferior preoperative VR-12 MCS/SF-12 PCS/PROMIS-PF/PHQ-9/ODI scores (p ≤ 0.003, all). At 6-weeks postoperatively, VR-12 PCS < 30 reported inferior VR-12 PCS/SF-12 PCS/PROMIS-PF/PHQ-9 (p ≤ 0.030, all). There was greater improvement up to 6-weeks postoperatively in VR-12 PCS < 30 for VR-12 PCS/MCS and SF-12 PCS (p ≤ 0.020, all). VR-12 PCS < 30 reported superior improvement by final follow-up in VR-12 PCS/SF-12 PCS/PHQ-9 (p ≤ 0.006, all). MCID achievement rates were higher in VR-12 PCS < 30 for PHQ-9 and ODI (p ≤ 0.013, both). VR-12 PCS < 30 patients reported inferior postoperative physical function, mental health, and disability, yet superior magnitude of improvement in physical function and mental health. Rates of clinically meaningful improvement for VR-12 PCS < 30 were greater in mental health and disability.

Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVE The aim was to compare patient-reported outcomes (PROMs), minimum clinically important difference (MCID) achievement, and postoperative satisfaction following minimally invasive lumbar decompression in patients stratified by American Society of Anesthesiologists (ASA) classification. SUMMARY OF BACKGROUND DATA Some guidelines recommend against performing elective procedures for patients with an ASA score of 3 or greater; however, long-term postoperative outcomes are not well described. METHODS Primary, single-level, minimally invasive lumbar decompression procedures were identified. PROMs were administered at preoperative, 6-week, 12-week, 6-month, 1-year, 2-year timepoints and included Patient-Reported Outcomes Measurement Information System-Physical Function, visual analog scale (VAS) back/leg, Oswestry disability index (ODI), and 12-item short form physical component score. Satisfaction scores were collected postoperatively for VAS back/leg, ODI, and individual ODI subcategories. Patients were grouped (ASA<3, ASA≥3), and propensity scores were matched to control for significant differences. Demographic and perioperative characteristics were compared using χ 2 and the Student's t test. Mean PROMs and postoperative satisfaction were compared at each time point by a 2-sample t test. Postoperative PROM improvement from the preoperative baseline within each cohort was calculated with a paired t test. MCID achievement was determined by comparing ΔPROMs to established thresholds and comparing between groups using simple logistic regression. RESULTS One hundred and twenty-nine propensity-matched patients were included: 99 ASA<3 and 30 ASA≥3. No significant demographic differences were observed between groups. ASA≥3 patients experienced significantly increased length of stay and postoperative narcotic consumption on surgery day ( P <0.048, all). Mean PROMs and MCID achievement did not differ. The ASA<3 cohort significantly improved from the preoperative baseline for all PROMs at all postoperative time points. ASA<3 patients demonstrated higher levels of postoperative satisfaction at 6 weeks for VAS leg, VAS back, ODI, sleeping, lifting, walking, standing, sex, travel, and at 6 months for VAS back ( P <0.045, all). CONCLUSION ASA≥3 patients may achieve similar long-term clinical outcomes to ASA<3 patients, though they may show poorer short-term satisfaction for disability, leg pain, and back pain, which could be related to differing preoperative expectations.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To characterize an experienced single surgeon learning curve for cervical disk replacement (CDR). SUMMARY OF BACKGROUND DATA A single surgeon learning curve has not been established for CDR. METHODS Patients undergoing CDR were included. The cumulative sum of operative time was utilized to separate cases into 3 phases: learning, practicing, and mastery. Demographics, perioperative characteristics, complications, patient-reported outcomes (PROs), and radiographic outcomes were collected preoperatively and up to 1 year postoperatively. PROs included Patient-reported Outcomes Measurement Information System Physical Function, 12-item Short Form-12 Physical Component Score, 12-item Short Form-12 Mental Component Score, visual analog scale (VAS) arm, VAS neck, Neck Disability Index. Radiographic outcomes included segmental angle/segmental range of motion/C2-C7 range of motion. Minimum clinically important difference achievement was determined through a comparison of previously established values. RESULTS A total of 173 patients were identified, with 14 patients in the learning phase, 42 patients in the practicing phase, and 117 patients in the mastery phase. Mean operative time and mean postoperative day 0 narcotic consumption were significantly higher in the learning phase. The preoperative segmental angle was significantly lower for the learning phase, though these differences were eliminated at the final postoperative time point. Patients in the learning phase reported worse improvement to 6-week postoperative, final postoperative, and worse overall final postoperative VAS Arm scores compared with practicing and mastery phases. CONCLUSIONS For an experienced spine surgeon, the learning phase for CDR was estimated to span 14 patients. During this phase, patients demonstrated longer operative times, higher postoperative narcotic consumption, and worse postoperative VAS Arm scores. Radiographically, no postoperative differences were noted between different phases of mastery. This single surgeon learning curve demonstrates that CDR may be performed safely and with comparable outcomes by experienced spine surgeons despite decreased operative efficiency in the learning phase.

Prognostic Value in Preoperative Veterans RAND-12 Mental Component Score on Clinical Outcomes for Patients Undergoing Minimally Invasive Lateral Lumbar Interbody Fusion. Neurospine 2024; 21:361-371. [PMID: 38291749 PMCID: PMC10992641 DOI: 10.14245/ns.2346730.365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 09/25/2023] [Accepted: 11/04/2023] [Indexed: 02/01/2024] Open
Abstract
OBJECTIVE To evaluate the effect of Veterans RAND 12-item health survey mental composite score (VR-12 MCS) on postoperative patient-reported outcome measures (PROMs) after undergoing lateral lumbar interbody fusion. METHODS Retrospective data from a single-surgeon database created 2 cohorts: patients with VR-12 MCS ≥ 50 or VR-12 MCS < 50. Preoperative, 6-week, and final follow-up (FF)- PROMs including VR-12 MCS/physical composite score (PCS), 12-item Short Form health survey (SF-12) MCS/PCS, Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), visual analogue scale (VAS)-back/leg pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected. ∆6-week and ∆FF-PROMs were calculated. Minimal clinically important difference (MCID) achievement rates were determined from established cutoffs from the literature. For intercohort comparison, chi-square analysis was used for categorical variables, and Student t-test for continuous variables. RESULTS Seventy-nine patients were included; 25 were in VR-12 MCS < 50. Mean postoperative follow-up time was 17.12 ± 8.43 months. The VR-12 MCS < 50 cohort had worse VR-12 PCS, SF-12 MCS, PROMIS-PF, PHQ-9, VAS-BP, and ODI scores preoperatively (p ≤ 0.014, all), worse VR-12 MCS/PCS, SF-12 MCS, PROMIS-PF, PHQ-9, and ODI scores at 6-week postoperatively (p ≤ 0.039, all), and worse VR-12 MCS, SF-12 MCS, PROMIS-PF, PHQ-9, VAS-BP, VAS-LP, and ODI scores at FF (p ≤ 0.046, all). The VR-12 MCS < 50 cohort showed greater improvement in VR-12 MCS and SF-12 MCS scores at 6 weeks and FF (p ≤ 0.005, all). The VR-12 MCS < 50 cohort experienced greater MCID achievement for VR-12 MCS, SF-12 MCS, and PHQ-9 (p ≤ 0.006, all). CONCLUSION VR-12 MCS < 50 yielded worse mental health, physical function, pain and disability postoperatively, yet reported greater improvements in magnitude and MCID achievement for mental health.

Abstract
OBJECTIVE To evaluate preoperative disability's influence on patient-reported outcomes (PROs) following surgery for degenerative spondylolisthesis (DS). METHODS DS patients who underwent surgical intervention were retrospectively identified from a single-surgeon spine registry. Cohorts based on Oswestry Disability Index (ODI) < 41 (milder disability) and ≥ 41 (severe disability) were created. Demographic differences were accounted for with 1:1 propensity score matching. For the matched sample, perioperative and PRO data were additionally collected. PROs assessed included mental health, physical function, pain, and disability. Pre- and up to 2-year postoperative PROs were utilized. Average time to final follow-up was 15.7 ± 8.8 months. Improvements in PROs and minimal clinically important difference (MCID) rates were calculated. Continuous variables were compared through Student t-test and categorical variables were compared through chi-square tests. RESULTS Altogether, 214 patients were included with 77 in the milder disability group. The severe disability group had worse postoperative day (POD) 1 pain scores and longer hospital stays (p ≤ 0.038, both). The severe disability group reported worse outcomes pre- and postoperatively (p < 0.011, all), but had greater average improvement in 12-item Short Form health survey mental composite score (SF-12 MCS), 9-Item Patient Health Questionnaire (PHQ-9), visual analogue scale (VAS)-back, and ODI by 6 weeks (p ≤ 0.037, all) and PHQ-9, VAS-back and ODI by final follow-up (p ≤ 0.015, all). The severe disability cohort was more likely to achieve MCID for SF-12 MCS, PHQ-9, and ODI (p ≤ 0.003, all). CONCLUSION Patients with greater baseline disability report higher POD 1 pain and discharge later than patients with milder disability. While these patients report inferior physical/mental health before and after surgery, they report greater improvements in mental health and disability postoperatively.

Abstract
The influence of Charlson Comorbidity Index (CCI) burden on Patient-Reported Outcomes Measurement Information System (PROMIS) outcomes following lumbar decompression (LD) is limited. The objective of this study is to evaluate CCI burden impact on PROMIS outcomes. Retrospective review of elective LD excluding revision or surgeries for infectious, malignant, or traumatic reasons. Demographics and PROMIS scores collected preoperatively and postoperatively up to 2 years included: PROMIS-Physical Function (PF)/Sleep Disturbance (SD)/Pain Interference (PI)/Anxiety (A), VR-12 Physical/Mental Health Composite scores (VR-12 PCS/MCS)/Oswestry Disability Index (ODI). Patients were divided into two groups based on their preoperative CCI score <3 (mild) or ≥4 (moderate to severe). Descriptive statistical analysis and MCID achievement rate calculations were conducted. A total of 182 patients were included: 93 CCI < 3 and 88 CCI ≥ 4. No significant differences were reported across preoperative PROMIS/legacy PROMs or final follow-up (p > 0.05, all). At 6-weeks, VR-12 PCS and ΔPROM scores indicated improved physician function in the CCI < 3 group (p = 0.020 and p = 0.040, respectively). Significant PROMIS-A ΔPROM score at final post-op was noted for CCI < 3 group (p = 0.026). MCID achievement demonstrated no significant differences for PROMIS outcomes and legacy PROMs. Results demonstrated that PROMIS outcomes were not impacted by a greater baseline comorbidity burden. At 6-weeks, the physical function scores were improved for the lower CCI group, and at final reported less anxiety. Our data suggests that comorbidity burden has a limited effect on PROMIS and legacy outcomes in patients undergoing LD.
