Critical Findings: Attempts at Reducing Notification Errors

PurposeIneffective communication of critical findings (CFs) is a patient safety issue. The aim of this study was to assess whether a feedback program for faculty members failing to correctly report CFs would lead to improved compliance.MethodsFifty randomly selected reports were reviewed by the chief of neuroradiology each month for 42 months. Errors included (1) not calling for a CF, (2) not identifying a CF as such, (3) mischaracterizing non-CFs as CFs, and (4) calling for non-CFs. The number of appropriately handled and mishandled reports in each month was recorded. The trend of error reduction after the division chief provided feedback in the subsequent months was evaluated, and the equality of time interval between errors was tested.ResultsAmong 2,100 reports, 49 (2.3%) were handled inappropriately. Among non-CF reports, 98.97% (1,817 of 1,836) were appropriately not called and not flagged, and 88.64% (234 of 264) of CF reports were called and flagged appropriately. The error rate during the 11th through 32nd months of review (1.28%) was significantly lower than the error rate in the first 10 months of review (3.98%) (P = .001). This benefit lasted for 21 months.ConclusionsReview and giving feedback to radiologists increased their compliance with the CF protocol and decreased deviations from standard operating procedures for about 2 years (from month 10 to month 32). Developing new ideas for improving CF policy compliance may be required at 2- to 3-year intervals to provide continuous quality improvement.     

Anterior cervical decompression and fusion for a single-level cervical disc herniation

Cervical radiculopathy is a clinical diagnosis consisting of sensory and/or motor symptoms in a nerve root distribution of the upper extremity. Operative management is frequently required to relieve symptoms. Anterior cervical decompression and fusion (ACDF) was originally described by Smith and Robinson and has been shown to be a relatively safe treatment approach to the cervical spine. Modern advances have helped to improve outcomes and decrease complications, including the development of bone grafting techniques, cage constructs, and augmentation of grafting with anterior plating systems. Anterior plating serves to increase fusion rates and maintain sagittal alignment. Despite advancements, complications still exist, including dysphagia, dural tear, adjacent segment disease, esophageal perforation, hardware failure, and recurrence of symptoms. We have reviewed the literature and shown that for single-level radiculopathy of a nerve root in the cervical spine, ACDF with plating is a favorable surgical treatment.     

Clinical Characteristics and Long-Term Outcomes of Movement Disorders in Childhood Thalamic Tumors

BackgroundWe studied the outcomes of movement disorders that were associated with childhood thalamic tumors.MethodsWe retrospectively reviewed 83 children with thalamic tumors treated at our institution from 1996 to 2013 to document the incidence and outcome of movement disorders. Magnetic resonance imaging was used to analyze the involvement of thalamic nuclei, and three instruments were used to rate the severity of the disorders.ResultsNine (11%) patients had one or more of the following movement disorders: postural tremor, resting tremor, ballism, dystonia, myoclonus, and athetosis. Median age at tumor diagnosis was seven years (range, 0.25 to 11 years), and the average age at movement disorder onset was eight years (range, 1.5 to 11 years). Movement disorders developed at a median of 1.5 months (range, 0 to 4 months) after surgical resection. The severity of the disorders was either unchanged or slightly improved during follow-up. The red nuclei were the only thalamic structures that showed tumor involvement in all nine patients.ConclusionsNo specific injury of the thalamic nuclei was associated with movement disorders in children with thalamic tumors, and the severity of these disorders did not change over time.     

Causes and outcomes of new onset status epilepticus and predictors of refractoriness to therapy

We aimed to evaluate the determinants of outcome in new onset refractory status epilepticus (SE). A retrospective analysis of patients with new onset SE admitted between May 2005 and October 2013 was performed. Regression analysis was used to determine factors that affect progression of new onset SE to refractory status epilepticus (RSE) and mortality. Among 114 patients with new onset SE, 52 patients progressed to RSE. Sixty seven (58.7%) were men. New onset RSE patients were younger than new onset SE patients (mean 35.9 ± standard deviation18.2 versus 28.7 ± 20.2 years; p = 0.050). Cryptogenic aetiology was the most significant determinant of progression of new onset SE to RSE (Exp [β] = 5.68; p = 0.001). The overall mortality in the entire group was 23.7%, significantly higher in new onset RSE group (40.4% versus 9.7%; p < 0.0001). New onset RSE patients with symptomatic and cryptogenic etiology did not differ for clinical characteristics and outcome. Acidosis was the strongest predictor of mortality in the entire cohort (Exp [β] = 8.72; p = 0.005). Nearly half of the patients with new onset SE progressed to RSE. While cryptogenic aetiology determined progression of new onset SE to RSE, acidosis was associated with mortality. The outcome was similar between symptomatic and cryptogenic new onset RSE.     

Prolonged length of stay after posterior surgery for cervical spondylotic myelopathy in patients over 65 years of age

Prolonged length of stay (PLOS) has been associated with increased hospital resource utilization and worsened patient outcomes in multiple studies. In this study, we defined and identified factors associated with PLOS after posterior surgery for cervical spondylotic myelopathy in patients over the age of 65. PLOS was defined as length of stay beyond the “prolongation point” (that is, the day after which discharge rates begin to decline). Using the United States Nationwide Inpatient Sample database, 2742 patients met inclusion criteria, out of whom 16.5% experienced PLOS (stay beyond 6 days). After multivariate analysis, increasing age was independently associated with PLOS (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02–1.06). Multiple comorbid conditions were associated with PLOS, including alcohol abuse (OR 3.85, 95% CI 1.87–7.94), congestive heart failure (OR 1.72, 95% CI 1.11–2.64), obesity (OR 1.70, 95% CI 1.14–2.55), and deficiency anemia (OR 1.44, 95% CI 1.01–2.05); the strongest associated operative parameter was blood transfusion (OR 2.39, 95% CI 1.75–3.28). Major complications independently associated with PLOS were deep vein thrombosis (OR 18.32, 95% CI 6.50–51.61), myocardial infarction (OR 8.98, 95% CI 2.92–27.56), pneumonia (OR 6.67, 95% CI 3.17–14.05), acute respiratory failure (OR 6.27, 95% CI 3.43–11.45), hemorrhage/hematoma (OR 5.04, 95% CI 2.69–9.44), and implant-related complications (OR 2.49, 95% CI 1.24–4.98). Average total hospital charges for patients who experienced PLOS were $122,965 US dollars, compared to $76,870 for the control group (p < 0.001). Mortality for patients who experienced PLOS was 2.7% versus 0.5% for patients who did not epxerience PLOS (p < 0.001). In conclusion, patients over the age of 65 who underwent posterior surgery for cervical myelopathy and stayed over 6 days in hospital were defined as having PLOS. Hospital charges and mortality rates were significantly higher for patients who experienced PLOS. Potentially modifiable and/or preventable risk factors were also identified.     

Schizophrenia and neurosurgery: A dark past with hope of a brighter future

Schizophrenia is a chronic and progressive psychiatric disease that remains difficult to manage in the 21st century. Current medical therapies have been able to give reprieve and decrease incidence of psychotic episodes. However, as the disease progresses, patients can become ever more refractory to current pharmaceutical agents and the polypharmacy that is attempted in treatment. Additionally, many of these drugs have significant adverse effects, leaving the practitioner in a difficult predicament for treating these patients. The history of neurosurgery for schizophrenia, among other psychiatric diseases, has a very dark past. Therefore, this review examines peer-reviewed studies on the history of schizophrenia, its medical and surgical therapies, financial costs, and future directions for disease management. We highlight the historically poor relationship between neurosurgery and psychiatric disease and discuss current research in the understandings of schizophrenia. Guided by a strong code of ethics and new technology, including the use of stereotaxis and deep brain stimulation (DBS), the medical communities treating psychiatric disease are beginning to overcome the horrors of the past. DBS is currently being used with moderate success in the treatment of depression, obsessive compulsive disorder, Tourette’s syndrome, and anorexia nervosa. With greater understanding of the neural circuitry of schizophrenia and the evolving role for DBS in psychiatric disease, the authors believe that schizophrenia, like other psychiatric diseases, can be treated with DBS.
