"peer-reviewed" in a known predatory journal. Be careful and do your research.

From one of the comments on the substack article:

A quick search for "Journal of Emergency Medicine: Open Access" finds it is part of the Longdom operation: https://www.longdom.org/emergency-medicine/peer-review-process.html.

If the "Journal of Emergency Medicine: Open Access" was a legitimate, properly peer-reviewed, mainstream journal it would be listed in PubMed, but it is not: https://pmc.ncbi.nlm.nih.gov/journals/. This lists seven journals which have the phrase "Journal of Emergency Medicine" in their titles, but not this one.

The publisher, Opast, is mentioned six times in this recent, mainstream, peer-reviewed journal, report on predatory journals: https://ese.arphahub.com/article/113535/ .

Both Opast and Longdom are listed on Beall's original list of predatory journals: https://beallslist.net and reports like these:
