Accuracy of Prehospital Services' Estimated Time to Arrival for Ground Transport to the Emergency Department.

BACKGROUND: Emergency medical services (EMS) transporting patients to the emergency department (ED) typically call ahead to provide an estimated time to arrival (ETA). Accurate ETA facilitates ED preparation and resource allotment in anticipation of patient arrival. OBJECTIVE: The study purposed to determine the accuracy of ETA provided by EMS ground units. METHODS: We performed a single-center, prospective, observational study of ED patients arriving via EMS ground transport. The primary outcome was the time difference between EMS-reported ETA and actual time of arrival (ATA). The difference between ATA and ETA was compared using the two-sided Wilcoxon Signed-Rank Test. Subgroup analysis was performed to evaluate ETA accuracy for specific types of transports and assess variability by month and time of day. RESULTS: We included 1176 patient transports in the final analysis. The overall median difference ATA-ETA was 3 min (interquartile range 1-5 min) with a range of -26-48 minutes (Z = -25.139, p < 0.001). EMS underestimated ETA in 961 cases (81.7%), and 94 ETAs (8.0%) were accurate to within 1 min. The largest difference between ATA and ETA occurred between 07:00-07:59 and 16:00-16:59 (5 min, interquartile range 2-7). CONCLUSION: Our data demonstrate that prehospital providers underestimate time to ED arrival in most ground transports; however, the median difference between estimated and actual time to arrival is small.

Amiodarone induced movement disorder after cardiac arrest - A case report.

We describe a case of new onset movement disorder in a patient with ventricular tachycardia storm supported with peripheral VA ECMO. The differential diagnosis of abnormal movements in a post cardiac arrest patient requiring temporary mechanical circulatory support for cardiogenic shock is explored.

Sonographic exploration for fascial exploration (SEFE) in necrotizing fasciitis: a case report.

BACKGROUND: Necrotizing skin and soft tissue infections are life-threatening conditions. Reliance on gas in tissue planes leads to worsened outcomes in patients with non-gas forming types of necrotizing fasciitis (NF). CASE PRESENTATION: We present a case of Group A Strep (GAS) necrotizing fasciitis, which was identified at bedside with point-of-care ultrasound (US) including an area of subfascial fluid. Computerized tomography only revealed diffuse cellulitic changes. Patient was taken to the operating room where fascial exploration was not performed at the concerning area seen on ultrasound and thus falsely negative. The patient subsequently developed multi-system organ failure and required amputation of the limb due to rapid spread of GAS NF. CONCLUSION: We suggest an US protocol to help identify optimal areas for fascial exploration-sonographic exploration for fascial exploration (SEFE).
