Sizzling thread. 🔥 IPAC is failing as a profession.
This should be front page news. 70% of patients requiring the hospital for Covid CAUGHT it in healthcare.
That’s an alarming amount of completely preventable hospitalizations.
Healthcare settings know how to stop spread.
Clean air & mandatory respirators. Forcibly infecting patients is wrong 🧵/1

Sizzling thread. 🔥 IPAC is failing as a profession.
Canadian IPAC is organizing *against* the new CSA standard that calls for respirator use in hospitals. It’s really important for the public to fight back against the IPAC powers who have denied respirator use and availability all along.
Hi all. It’s tremendously important that between now and Aug 19 (deadline) that you provide public comment to CSA on the newest revisions to Z94.4: selection, use, and care of respirators. For the first time ever it includes healthcare. Must make CSA account. publicreview.csa.ca/Home/Details...
