Functional outcome and survival following spontaneous intracerebral hemorrhage: A retrospective population-based study.

Background: Accurate and reliable clinical and radiological predictors of intracerebral hemorrhage (ICH) outcomes are needed to optimize treatment of ICH. The aim of this study was to investigate functional outcome and identify predictors of severe disability or death following ICH.

Materials And Methods: Retrospective population-based study of spontaneous ICH.

Risk of intracranial hemorrhage (RICH) in users of oral antithrombotic drugs: Nationwide pharmacoepidemiological study.

Background: The risks of intracranial haemorrhage (ICH) associated with antithrombotic drugs outside clinical trials are gaining increased attention. The aim of this nationwide study was to investigate the risk of ICH requiring hospital admission in users of antithrombotic drugs.

Methods And Findings: Data from the Norwegian Patient Registry and Norwegian Prescription Database were linked on an individual level.

Validation of intracranial hemorrhage in the Norwegian Patient Registry.

Objectives: Administrative health registries need to have accurate diagnoses and sufficient coverage in the population they serve in order to be useful in research. In this study, we investigated the proportion of discharge diagnoses of intracranial hemorrhage (ICH) that were coded correctly in the Norwegian Patient Registry (NPR).

Materials And Methods: We reviewed the electronic medical records and diagnostic imaging of all admissions to St.

Lumbar microdiscectomy for sciatica in adolescents: a multicentre observational registry-based study.

Background: Lumbar disc herniation (LDH) is rare in the adolescent population. Factors predisposing to LDH in adolescents differ from adults with more cases being related to trauma or structural malformations. Further, there are limited data on patient-reported outcomes after lumbar microdiscectomy in adolescents.

Open discectomy vs microdiscectomy for lumbar disc herniation - a protocol for a pragmatic comparative effectiveness study.

:  Since the introduction of lumbar microdiscectomy in the 1970's, many studies have attempted to compare the effectiveness of this method with that of standard open discectomy with conflicting results. This observational study is designed to compare the relative effectiveness of microdiscectomy (MD) with open discectomy (OD) for treating lumbar disc herniation, -within a large cohort, recruited from daily clinical practice.   This study will include patients registered in the Norwegian Registry for Spine Surgery (NORspine).

Surgery for Lumbar Spinal Stenosis in Individuals Aged 80 and Older: A Multicenter Observational Study.

Objectives: To compare clinical outcomes after decompressive surgery for central lumbar spinal stenosis (LSS) in individuals aged 80 and older with those of individuals aged 18-79.

Design: Prospective data from the Norwegian Registry for Spine Surgery.

Setting: Multicenter observational study.

Surgery for lumbar spinal stenosis in patients with rheumatoid arthritis: A multicenter observational study.

Objective: To compare clinical outcomes following microdecompression surgery or laminectomy for central lumbar spinal stenosis (LSS) between patients with rheumatoid arthritis (RA) and patients without rheumatic disease.

Material And Methods: Data were collected from the Norwegian Registry for Spine Surgery. The primary outcome was change in the Oswestry Disability Index (ODI) score at 1 year.

Risk of intracranial hemorrhage in users of oral antithrombotic drugs: Study protocol for a nationwide study.

Background A wide range of antithrombotic medications can be used in the prevention and treatment of thrombosis. Among hemorrhagic complications of antithrombotic drugs, intracranial hemorrhage may have particularly devastating consequences with high morbidity, disability and mortality rates. The incidence and risks of intracranial hemorrhage in patients on antithrombotic treatments from regular clinical practice outside clinical trials remain largely unknown.

Is There an Association Between Radiological Severity of Lumbar Spinal Stenosis and Disability, Pain, or Surgical Outcome?: A Multicenter Observational Study.

Study Design: Observational multicenter study.

Objective: To evaluate if the severity of lumbar spinal stenosis (LSS) on magnetic resonance imaging (MRI) correlates with preoperative disability, pain, or surgical outcomes.

Summary Of Background Data: Surgeons use the morphological appearance of LSS on MRI for clinical decision making.

Does Obesity Affect Outcomes After Decompressive Surgery for Lumbar Spinal Stenosis? A Multicenter, Observational, Registry-Based Study.

Objective: To evaluate the association between obesity and outcomes 1 year after laminectomy or microdecompression for lumbar spinal stenosis (LSS).

Methods: The primary outcome measure was the Oswestry Disability Index (ODI). Obesity was defined as body mass index (BMI) ≥ 30.

The Risk of Getting Worse: Predictors of Deterioration After Decompressive Surgery for Lumbar Spinal Stenosis: A Multicenter Observational Study.

Objective: To investigate the frequency and predictors of deterioration after decompressive surgery for single and 2-level lumbar spinal stenosis.

Methods: Prospectively collected data were retrieved from the Norwegian Registry for Spine Surgery. Clinically significant deterioration was defined as an 8-point increase in Oswestry disability index (ODI) between baseline and 12 months' follow-up.

Microsurgical decompression for central lumbar spinal stenosis: a single-center observational study.

Objective: To assess outcomes and complications in patients undergoing microsurgical decompression for central lumbar spinal stenosis (LSS) without radiologic instability.

Methods: Prospective data for patients operated at the Department of Neurosurgery, St. Olavs University Hospital, Norway, were obtained from the Norwegian Registry for Spine Surgery (NORspine) from 2007 to 2012.

Does daily tobacco smoking affect outcomes after microdecompression for degenerative central lumbar spinal stenosis? - A multicenter observational registry-based study.

Background: There are limited scientific data on the impact of smoking on patient-reported outcomes following minimally invasive spine surgery. The aim of this multicenter observational study was to examine the relationship between daily smoking and patient-reported outcome at 1 year using the Oswestry Disability Index (ODI) after microdecompression for single- and two-level central lumbar spinal stenosis (LSS). Secondary outcomes were the length of hospital stays, perioperative and postoperative complications.
