The primary outcome was the proportion of visits in which patients received opioid analgesia within 30 min of triage. Secondary outcomes were time in minutes from triage to any analgesic administration and time from triage to first opioid administration. Patient demographics and ED encounter characteristics were included as potential associated variables.</p><p><strong>Results: </strong>There were 236 patient visits (by 103 patients) that met inclusion criteria.

While computerized algorithms for ECG interpretation are limited in their accuracy, machine learning (ML) models have shown promise in several areas of clinical medicine. We performed a systematic review to compare the performance of ML-based ECG analysis to clinician or non-ML computerized ECG interpretation in the diagnosis of ACS for emergency department (ED) or prehospital patients.</p><p><strong>Methods: </strong>We searched Medline, Embase, Cochrane Central, and CINAHL databases from inception to May 18, 2022. We included studies that compared ML algorithms to either clinicians or non-ML based software in their ability to diagnose ACS using only a 12-lead ECG, in adult patients experiencing chest pain or symptoms concerning for ACS in the ED or prehospital setting.
