Interesting leap of faith/prejudice to say masks cause confusion & therefore medical errors.

If you look into that statistic it’s not surgeons cutting an artery by mistake etc, that’s vanishingly rare. The “mistakes” are judgment calls like is this sepsis, do the benefits of prophylaxis for VTE outweigh the risks of bleeding or is this 89year old diabetic fit for a procedure or not to fix their broken hip.

Hindsight shows people get these judgment calls wrong at times but unfortunately for you these are decisions that were always made in an environment without masks although maybe there was tiredness involved from inadequate rest during a 48 hour on-call.
