The study you link has literally nothing to do with your claim.
Do you find it weird that people die in ERs sometimes, and it happens more often in overcrowded ERs, as the study you link suggests? Because that’s what it’s saying. That long triage times and short staffing leads to worse patient outcomes… And surprise, this study was in 2021, still peak COVID year.
