Potential Impact of C-STAT for Prehospital Stroke Triage Up to 24 Hours on a Regional Stroke System.
Background and Purpose: Thrombectomy for large vessel occlusion acute ischemic stroke (AIS-LVO) may benefit patients up to 24 hour since last known normal (LKN). Prehospital tools, like the Cincinnati Stroke Triage Assessment Tool (C-STAT), are used to select hospital destination for suspected AIS-LVO patients. The objective of this study was to estimate the potential impact of the expanded thrombectomy time window on suspected AIS-LVO cases transported to the regional comprehensive stroke center (CSC). ⋯ Of 37 C-STAT + patients, only 5 (13.5%) had LVO as final diagnosis. Conclusions: Preferential triage of prehospital suspected stroke patients using C-STAT would increase the number of patients transported to the CSC by 11% within six hours and an additional 10% from six to 24 hours. For every patient with LVO as final diagnosis, approximately an additional 6 non-LVO patients would be triaged to a CSC.

Venous air embolisms are rare but a cause of potentially life-threatening events with associated cardiovascular, pulmonary and neurologic effects. We report the first prehospital case of a venous air embolism in a 31-year-old male who became hemodynamically unstable after a peripheral intravenous catheter with unprimed tubing was placed by paramedics in the prehospital setting and diagnosed in the emergency department. We highlight the clinical presentation, diagnosis and emergency management of venous air embolisms.

Background: Chest pain is a leading complaint in emergency settings. Timely emergency medical services (EMS) responses can reduce delays to treatment and improve clinical outcomes for acute myocardial infarction patients and other medical emergencies. We investigated national-level EMS response, scene, and transport times for acute chest pain patients in the United States. ⋯ Regional and urban-rural differences were observed in adherence with the response time benchmark. Our findings also suggest age and gender disparities in on-scene delays by EMS. Our study contributes important evidence on timely EMS responses for cardiac chest pain and provides suggestions for EMS system benchmarking and quality improvement.
