Background and purposes: Stroke severity scales may expedite prehospital large vessel occlusion (LVO) stroke detection, but few are validated for paramedic use. We evaluated the feasibility of introducing the Cincinnati Stroke Triage Assessment Tool (C-STAT) in the field and its capacity to detect LVO stroke. Methods: We performed a prospective paramedic-based study assessing C-STAT in the field on patients currently redirected to two comprehensive stroke centers (CSC), based on a Cincinnati Prehospital Stroke Scale (CPSS) score of 3/3. ⋯ In a cohort of 100 patients with CPSS 3/3, requiring a positive C-STAT for redirection would decrease CSC patient volume by 37 but miss 9 of 36 LVO strokes. Conclusion: Prehospital administration of the C-STAT was feasible, using a model of minimal paramedic training and real-time telephone guidance. A protocol based on both a CPSS 3/3 and a positive C-STAT would decrease CSC redirected patient volume by one-third but would miss one-quarter of LVO strokes when compared to a CPSS-based protocol.

Case Reports
Prehospital Sinus Node Dysfunction and Asystole in a Previously Healthy Patient With COVID-19.
We report a case of a previously healthy 47-year-old female with syncope due to multiple episodes of nodal dysfunction and asystole. During these brief episodes, she was hypoxic in the mid-80's as a result of COVID-19 pneumonia. ⋯ As she recovered from COVID-19, no further episodes of bradycardia or bradyarrhythmia were noted. This case highlights a growing body of evidence that arrhythmias, specifically bradycardia, should be anticipated by prehospital providers as a potential cardiac complication of SARS-CoV-2 infection.

Emergency ambulance service in Harlem, New York was studied to determine the degree to which misuse exists. Data were collected prospectively from a paramedic (ALS) ambulance and a basic life support (BLS) ambulance dispatched from Harlem Hospital. The results show that only 29.5% of the 136 calls dispatched to the ALS unit had congruent dispatch and actual priorities (r = 0.05), and only 59.6% of the 255 calls handled by both units were recommended for the unit with the proper level of the skill. 69.9% of calls assigned to the ALS unit were found not to need emergency transport (ET), the most common reason being the "unfounded" call, which represented 35.3% of the sample. ⋯ While the data are now historical, having been collected nearly 40 years ago, this research provides useful insights into current EMS initiatives, notably: (1) accuracy of assigned dispatch priority, (2) need for emergency transport to an emergency department, and (3) willingness of paramedics to refuse transport in cases where it is deemed unnecessary. The research questions represent many of the challenges that persist in today's EMS world with some being particularly relevant with the advent of Community Paramedicine. Emergency Ambulance Utilization in Harlem truly illustrates "what's old is new again!"

Background: Getting effective fall prevention into the homes of medically and physically vulnerable individuals is a critical public health challenge. Community paramedicine is emerging globally as a new model of care that allows emergency medical service units to evaluate and treat patients in non-emergency contexts for prevention efforts and chronic care management. The promise of community paramedicine as a delivery system for fall prevention that scales to community-level improvements in outcomes is compelling but untested. ⋯ Results: Community paramedic home visits increased from 25 in 2017, to 236 in 2018, to 517 in 2019, indicating a large increase in the number of households that benefited from the efforts. A relative risk reduction of 0.66 (95% [CI] 0.53, 0.76) in the number of fall calls and 0.63 (95% [CI] 0.46, 0.75) in the number of fall-related calls resulting in transports to the hospital were observed. Conclusions: Community-FIT may offer a powerful mechanism for community paramedics to reduce fall-related 9-1-1 calls and transports to hospitals that can be implemented in emergency medical agencies across the country.
