Sympathetic hyperactivity syndrome following cerebral fat embolization

To date, there have been no reports of paroxysmal sympathetic hyperactivity syndrome (PSHS) associated with cerebral fat embolization. We describe the case of a young male who developed acute brain injury and acute hypoxemic respiratory failure secondary to significant fat embolization following a traumatic femur injury. Our patient demonstrated episodes of significant hypertension, tachycardia, fever and extensor posturing. Extensive evaluation lead to the diagnosis and appropriate treatment for PSHS. Ultimately, the patient went on to have a good neurologic recovery after a prolonged hospitalization. We will discuss PSHS diagnostic criteria, pathophysiology and treatment options. This diagnosis should be considered in all brain-injured patients with paroxysms of autonomic instability and abnormal movements

Retrospective derivation and validation of a search algorithm to identify extubation failure in the intensive care unit

BACKGROUND: Development and validation of automated electronic medical record (EMR) search strategies is important in identifying extubation failure in the intensive care unit (ICU). We developed and validated an automated search algorithm (strategy) for extubation failure in critically ill patients. METHODS: The EMR search algorithm was created through sequential steps with keywords applied to an institutional EMR database. The search strategy was derived retrospectively through secondary analysis of a 100-patient subset from the 978 patient cohort admitted to a neurological ICU from January 1, 2002, through December 31, 2011(derivation subset). It was, then, validated against an additional 100-patient subset (validation subset). Sensitivity, specificity, negative and positive predictive values of the automated search algorithm were compared with a manual medical record review (the reference standard) for data extraction of extubation failure. RESULTS: In the derivation subset of 100 random patients, the initial automated electronic search strategy achieved a sensitivity of 85% (95% CI, 56%-97%) and a specificity of 95% (95% CI, 87%-98%). With refinements in the search algorithm, the final sensitivity was 93% (95% CI, 64%-99%) and specificity increased to 100% (95% CI, 95%-100%) in this subset. In validation of the algorithm through a separate 100 random patient subset, the reported sensitivity and specificity were 94% (95% CI, 69%-99%) and 98% (95% CI, 92%-99%) respectively. CONCLUSIONS: Use of electronic search algorithms allows for correct extraction of extubation failure in the ICU, with high degrees of sensitivity and specificity. Such search algorithms are a reliable alternative to manual chart review for identification of extubation failure

A Disclosure About Death Disclosure: Variability in Circulatory Death Determination

Introduction. Circulatory-respiratory death declaration is a common duty of physicians, but little is known about the amount of education and physician practice patterns in completing this examination. Methods. We conducted an online survey of physicians evaluating the rate of formal training and specific examination techniques used in the pronouncement of circulatory-respiratory death. Data, including level of practice, training received in formal death declaration, and examination components were collected. Results. Respondents were attending physicians (52.4%), residents (30.2%), fellows (10.7%), and interns (6.7%). The majority of respondents indicated they had received no formal training in death pronouncement, however, most reported self-perceived competence. When comparing examination components used by our cohort, 95 different examination combinations were used for death pronouncement. Conclusions. Formal training in death pronouncement is uncommon and clinical practice varies. Implementation of formal training and standardization of the examination are necessary to improve physician competence and reliability in death declarations

Refractory Intracranial Hypertension due to Fentanyl Administration Following Closed Head Injury

BackgroundAlthough the effects of opioids on intracranial pressure have long been a subject of controversy, they are frequently administered to patients with severe head trauma. We present a patient with an uncommon paradoxical response to opioids.Case ReportA patient with refractory intracranial hypertension after closed head injury was managed with standard medical therapy with only transient decreases in the intracranial pressure. Only after discontinuation of opiates did the intracranial pressure become manageable without metabolic suppression and rescue osmotic therapy, implicating opiates as the etiology of refractory intracranial hypertension in this patient. ConclusionsClinicians should consider opioids as a contributing factor in malignant intracranial hypertension when findings on neuroimaging do not explain persistent and refractory intracranial hypertension

At the Intersection of Patient Experience Data, Outcomes Research, and Practice: Analysis of HCAHPS Scores in Neurology Patients

Objective: To assess variation in patient-reported experience in inpatient neurology patients. Patients and Methods: We retrospectively identified 1045 patients 18 years and older admitted to a neurology service and discharged from January 1, 2013, through September 30, 2016, who completed Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys. Multivariable logistic regression evaluated the associations of patient factors with HCAHPS measures. Key driver analysis identified associations between HCAHPS measures and the Global score (combination of 0-10 hospital rating and likelihood to recommend). Multivariable logistic regression compared HCAHPS scores between neurology patients and those admitted to a neurosurgery (n=2190) or internal medicine (n=3401) service during the same period. Results: Among patients admitted to a neurology service, overall (summary) scores did not vary significantly by diagnosis after adjustment for age, education, and overall health, but patients with neurologic diagnoses other than stroke, epilepsy, and neurodegenerative disease were more likely to report lower Pain Management scores compared with patients with cancer. Key driver analysis showed Care Transition scores as drivers of the Global score. After adjustment, general internal medicine service patients were more likely to report low Summary scores and neurosurgery service patients were significantly less likely to report low Summary scores compared with neurology service patients. Conclusion: Efforts to improve how neurology patients experience their care should be aimed at targeting patients' perceptions of pain management, and improving care transitions is an important first-priority target for improvement. This analysis may help other institutions improve hospital rating, value-based payments, and patient-centered outcomes
