Prevention today matters exponentially more than prevention tomorrow, esp in the middle a surge
Hospitals should not be dragging their feet on preventing in-hospital transmission
Many are patients who despite vaccinations can get very sick. We would know — we are treating them
2/ Mandatory N95 mask use for patient care should be initiated.
For hospitals that do not have capacity to do so, this should at minimum be initiated for the care of immunocompromised patients.
We have documented cases of transmission despite surgical mask use
3/ There are likely many more cases of this that are completely undercounted because most hospitals would not track/trace & sequence to confirm this.
But where they have, they have found it.
With transmissibility of #Omicron, expect to see this even more.
4/ At Stanford alone, where we have excellent testing of healthcare personnel, we have found more infections than any other week in the entire pandemic. Imagine what other hospitals are like that are not testing as frequently
I know there are a lot of amazing journalists covering #covid19. Can someone please look into this— this is from the 3M technical briefing Aug 2021 on their public respirator models where they mention 2 models from 2008 made for a pandemic crisis that were discontinued
2/ what happened to these— why was there no effort to scale up respirators for the public, ESPECIALLY if they already existed and had been approved for this purpose in the past?
3/ I can understand if these weren’t ready to go in March 2020– we were caught off guard. But between then & vaccines in December 2020, there were months without any action. Also, all of 2021– knowing vaccines didn’t provide sterilizing immunity— what happened?
*MUST READ*
This August 2021 technical bulletin by 3M is a must read— it covers all the questions you would have about respirators for the public; the limits of surgical & cloth masks; fit, filtration & more
They even mention that FDA had approved 3M respirators 8612F and 8670F for an airborne infectious disease outbreak; they were discontinued “following a long period of inactivity”
If your hospital only requires N95 for aerosol generating procedures, they are wrong
“the term aerosol-generating is a misnomer. It is not the procedure that increases risk but sustained proximity to the respiratory tract of a highly symptomatic patient.” jamanetwork.com/journals/jamas…
“These factors explain the intubation paradox, the fact that controlled intubations generate negligible amounts of aerosols (far less than volitional coughing), but intubation has repeatedly been associated with increased risk for health care worker infections.”
“The answer is that intubating a patient with viral respiratory failure forces the operator to be very close to the respiratory tract of a highly symptomatic patient, often while also forcing gas over the respiratory mucosa…”
