The "DeyeCOM Sign": Predictive Value in Acute Stroke Code Evaluations.

BACKGROUND: Rapid diagnosis in stroke is critical. Computed tomography is often performed initially, even before a neurologic examination. Gaze deviation has been correlated with stroke diagnosis in some cohorts. Conjugate gaze deviation on stroke code imaging, the "DeyeCOM sign," may have emergency stroke care implications. METHODS: We evaluated stroke code imaging from the University of California, San Diego database (2007-2013) for "DeyeCOM sign" diagnostic and predictive utility. Patients were grouped as DeyeCOM+ if conjugate gaze deviation was noted. The differences were assessed using the Fisher exact test for categorical and the Wilcoxon rank-sum test for continuous variables. RESULTS: We evaluated 342 patients; 106 (31%) were DeyeCOM+. Mean age was 63. The most common diagnoses in the DeyeCOM+ group were ischemic stroke (50.94%), transient ischemic attack (8.49%), other (8.49%), somatization (6.6%), and hemorrhage (5.66%). The National Institutes of Health Stroke Scale was greater in stroke patients than that in nonstroke (8.2 versus 3.8; P < .0001), and in DeyeCOM+ compared with DeyeCOM- (6.8 versus 5.6; P = .03). DeyeCOM+ patients were more likely to have a +gaze score (26.4% versus 9.8%; P < .0001), and +gaze patients were more likely to have final stroke diagnosis (26.0% versus 3.6%; P < .0001). There was no overall difference between groups in final stroke diagnosis; however, patients with deviation of 15° or more were more likely to have final diagnosis stroke (63.9% versus 47.9%; P = .03). CONCLUSIONS: DeyeCOM+ patients scored higher and were more likely to have +gaze on the stroke scale, and deviation of 15° or more was correlated with final diagnosis stroke. In current environments, there is pressure to complete stroke evaluations rapidly. Reliable imaging information obtained early (such as gaze deviation on scan correlating with scale score and final stroke diagnosis) could augment decision making even with negative imaging.

More Than a Perioperative Surgical Home: An Opportunity for Anesthesiologists to Advance Public Health.

Public health and the medical specialty of anesthesiology have been closely intertwined throughout history, dating back to the 1800s when Dr. John Snow used contact tracing methods to identify the Broad Street Pump as the source of a cholera outbreak in London. During the COVID-19 pandemic, leaders in anesthesiology and anesthesia patient safety came forward to develop swift recommendations in the face of rapidly changing evidence to help protect patients and healthcare workers. While these high-profile examples may seem like uncommon events, there are many common modern-day public health issues that regularly intersect with anesthesiology and surgery. These include, but are not limited to, smoking; chronic opioid use and opioid use disorder; and obstructive sleep apnea. As an evolving medical specialty that encompasses pre- and postoperative care and acute and chronic pain management, anesthesiologists are uniquely positioned to improve patient care and outcomes and promote long-lasting behavioral changes to improve overall health. In this article, we make the case for advancing the role of the anesthesiologist beyond the original perioperative surgical home model into promoting public health initiatives within the perioperative period.
