Postarrest Neuroprognostication: Practices and Opinions of Canadian Physicians.

BACKGROUND: Objective, evidence-based neuroprognostication of postarrest patients is crucial to avoid inappropriate withdrawal of life-sustaining therapies or prolonged, invasive, and costly therapies that could perpetuate suffering when there is no chance of an acceptable recovery. Postarrest prognostication guidelines exist; however, guideline adherence and practice variability are unknown. OBJECTIVE: To investigate Canadian practices and opinions regarding assessment of neurological prognosis in postarrest patients. METHODS: An anonymous electronic survey was distributed to physicians who care for adult postarrest patients. RESULTS: Of the 134 physicians who responded to the survey, 63% had no institutional protocols for neuroprognostication. While the use of targeted temperature management did not affect the timing of neuroprognostication, an increasing number of clinical findings suggestive of a poor prognosis affected the timing of when physicians were comfortable concluding patients had a poor prognosis. Variability existed in what factors clinicians' thought were confounders. Physicians identified bilaterally absent pupillary light reflexes (85%), bilaterally absent corneal reflexes (80%), and status myoclonus (75%) as useful in determining poor prognosis. Computed tomography, magnetic resonance imaging, and spot electroencephalography were the most useful and accessible tests. Somatosensory evoked potentials were useful, but logistically challenging. Serum biomarkers were unavailable at most centers. Most (79%) physicians agreed ≥2 definitive findings on neurologic exam, electrophysiologic tests, neuroimaging, and/or biomarkers are required to determine a poor prognosis with a high degree of certainty. Distress during the process of neuroprognostication was reported by 70% of physicians and 51% request a second opinion from an external expert. CONCLUSION: Significant variability exists in post-cardiac arrest neuroprognostication practices among Canadian physicians.

Choosing Wisely Neurology: Recommendations for the Canadian Neurological Society.

BACKGROUND: Choosing Wisely Canada (CWC) is a national branch of a global campaign advocating for fewer unnecessary tests and for optimizing patient care. Professional societies representing physicians, pharmacists, and nurses participate by generating lists of recommendations meant to reduce patient harm and resource mismanagement in healthcare. The Canadian Neurological Society (CNS) plays an important role in advocating for quality patient care demonstrated by deriving specific recommendations. This process is described. METHOD: The CNS Choosing Wisely task force adapted 10 recommendations for Canadian neurology practice. These were approved by the CNS board, and subsequently ranked by CNS members. RESULTS: Ten recommendations were brought forward and ranked in a survey completed by CNS members. Survey ranking is presented. The top five recommendations were selected and optimized, resulting in seven key recommendations. CONCLUSION: The recommendations set forth by the CNS will help with resource stewardship and patient safety in the delivery of neurological care by healthcare providers in Canada.
