Here is why hospitals need to ditch universal masking
Let's weight the possible upside vs. the possible downside
๐Ÿงต
All policy is tradeoffs
Science helps you articulate the tradeoffs, but only people can decide
In 2022, what is the tradeoff to masking in hospitals?
First, the upside. It is possible that masking in hospitals slows viral spread in hospitals, but as more and more of life outside returns to normal, as virus spread becomes inevitable, as more and more people have and recover from it-- this effect matters less
The worst part...
We actually don't know if it even works at all. There are zero well done studies; There are 1000s of studies with confounders/ biases/ lack of control groups but nearly no estimates bias free
And worse, none of these apply to the present day. Some apply to 2020
Now the downside: it impairs conversation; is uncomfortable; bad for people who are having a hard time breathing or hearing.
And furthers the crisis of depersonalization in western medicine
This too has been poorly quantified because: no good studies
Tie breaker: in cases like this, the tie breaker is: people should be free to do what they wish, until you bring evidence to show otherwise.
In this case, that means your 3 years are up. You conducted zero credible studies. No further case to impose on others.
I make the case against this policy for @Sensible__Med
I should add the worst injustice is making pregnant women give birth wearing a mask after they test negative and the staff masks and everyone has been vaccinated.
Just madness!!!
