Comparative analysis of lumbar spinal decompression: Propensity-matched evaluation of multilevel vs. single-level decompression for spinal stenosis.

Introduction: Lumbar spinal stenosis results in pain in the buttocks and/or legs due to reduced space in the spinal canal. MRI findings indicate that approximately 40 % of clinically diagnosed patients have multilevel stenosis. For patients with severe symptoms requiring spinal decompression, surgeons must decide the optimal number of levels to decompress.

External validation of a prediction model for disability and pain after lumbar disc herniation surgery: a prospective international registry-based cohort study.

Background And Purpose:  We aimed to externally validate machine learning models developed in Norway by evaluating their predictive outcome of disability and pain 12 months after lumbar disc herniation surgery in a Swedish and Danish cohort.

Methods:  Data was extracted for patients undergoing microdiscectomy or open discectomy for lumbar disc herniation in the NORspine, SweSpine and DaneSpine national registries. Outcome of interest was changes in Oswestry disability index (ODI) (≥ 22 points), Numeric Rating Scale (NRS) for back pain (≥ 2 points), and NRS for leg pain (≥ 4 points).

Effectiveness, usability, and patient satisfaction of an mHealth application with an integrated ePRO system following lumbar degenerative spinal surgery: A quasi-experimental study.

Introduction: There is a lack of comprehensive clinical research to assess potential benefits of mHealth solutions in post discharge follow-up care after spinal surgery.

Purpose: This quasi-experimental study evaluated the effectiveness, usability, and patient satisfaction of an mHealth pathway with an electronic Patient-Reported Outcome (ePRO)-based post-discharge nurse-led intervention for patients undergoing surgery for lumbar spine degenerative disorders, compared to standard care.

Methods: Conducted at a Danish tertiary spine center, this study represents the final stage of a three-phase participatory design.

Comparing Patient-Reported Outcomes of Lateral to Paramedian Lumbar Disc Herniation: A Propensity Score-Matched Observational Study.

Objective: To investigate patient-reported outcomes following lumbar discectomy in patients with lateral lumbar disc herniation (LDH) compared with patients with paramedian LDH.

Methods: Data on patients with lateral and paramedian LDH operated on between 2017 and 2020 at a single public spine unit were extracted from the National Danish Spine Registry, DaneSpine. A propensity score-matched, case-control analysis was conducted to compare the 2 groups.

A propensity-matched study of patients with symptomatic lumbar spinal stenosis opting for surgery versus not.

Introduction: Although most surgeons treating patients with lumbar spinal stenosis (LSS) believe that surgical treatment is superior to conservative measures, systematics reviews have concluded that no solid evidence support this.

Research Question: To compare change at 1-year of walking ability, health-related quality of life, leg and back pain in patients with symptomatic LSS referred to a spine surgery clinic who opted for surgery and those who did not.

Material And Methods: The study included 149 operated and 149 non-operated patients seen by spine surgeons and diagnosed with LSS.

Usability and performance expectancy govern spine surgeons' use of a clinical decision support system for shared decision-making on the choice of treatment of common lumbar degenerative disorders.

Study Design: Quantitative survey study is the study design.

Objectives: The study aims to develop a model for the factors that drive or impede the use of an artificial intelligence clinical decision support system (CDSS) called PROPOSE, which supports shared decision-making on the choice of treatment of ordinary spinal disorders.

Methods: A total of 62 spine surgeons were asked to complete a questionnaire regarding their behavioral intention to use the CDSS after being introduced to PROPOSE.

Impact of Preoperative Duration of Symptoms on Patient Satisfaction, Outcomes and Complications After Lumbar Discectomy: A Propensity-matched Comparison.

Study Design: Observational study.

Objective: To identify associations between preoperative symptom duration and postoperative patient satisfaction.

Summary Of Background Data: Sciatica due to lumbar disk herniation (LDH) is a cause of disability and reduced quality life.

Validating the predictive precision of the dialogue support tool on Danish patient cohorts.

Background: Despite advances in surgical techniques and diagnostics, some patients remain unsatisfied with the result following spine surgery. One way to improve patient satisfaction may be found in better alignment of expectations. Prognostic tools might prove useful in strengthening surgeon-patient communication prior to surgery.

Wide Laminectomy, Segmental Bilateral Laminotomies, or Unilateral Hemi-Laminectomy for Lumbar Spinal Stenosis: Five-year Patient-reported Outcomes in Propensity-matched Cohorts.

Study Design: Propensity-matched retrospective study of patients prospectively enrolled in Danespine.

Objective: The aim of this study was to report 5-year patient reported outcome in lumbar spinal stenosis (LSS) patients who underwent wide laminectomy (WL), segmental bilateral laminotomies (SBL), or unilateral hemilaminectomy (UHL) with bilateral decompression.

Summary Of Background Data: The optimal procedure for LSS remains controversial.

Applied Machine Learning for Spine Surgeons: Predicting Outcome for Patients Undergoing Treatment for Lumbar Disc Herniation Using PRO Data.

Study Design: Retrospective/prospective study.

Objective: Models based on preoperative factors can predict patients' outcome at 1-year follow-up. This study measures the performance of several machine learning (ML) models and compares the results with conventional methods.
