I have a patient with SARS and I want to keep my other patients and staff safe.
I look up the NIPCM Scotland and find that the Main (singular) mode of transmission is both Droplet / Airborne
@P_H_S_Official this thread merits "immediate action"
The Transmission Based Precautions Section tells me there are 3 modes of transmission.
It tells me what the different precautions are aiming to achieve
Of note the definitions of respiratory infections are erroneous
In the respiratory section
It tells me you only need RPE if the pathogen is "wholly" transmitted by the airborne route, i.e., not droplet / airborne, or AGP
Off for the literature review to find the evidence for this statement
I honestly believe IPC as a profession will NOT survive intact if it fails to accept airborne transmission as a significant ubiquitous risk and erroneously considers hand hygiene the single most important measure to prevent infection - it is not.
See below
Most important measures to prevent 🫁 non VAP pneumonia - patient positioning, mobility, oral hygiene
Most important measures to prevent surgical site infection 🩹: sterile instruments & theatre air quality
They have withdrawn masks in Scotland's Healthcare system and referred 'concerned staff' to complete a risk assessment. healthyworkinglives.scot/resources/form…
Lets fill out their risk assessment...
I am (for the form) a ward manager
Describe the task:
Any patient-to-HCW, HCW-to-HCW, patient-to-patient, or visitor-to-patient or HCW interaction in any close space, e.g. conversation or stethoscope range
or when ventilation poor just being on the ward.
Where is the task to be carried out?
Every minute of every day on this ward we are continuously interacting and at risk of inhaling someone else's exhaled air + virus.
Inhalation at distance is also a risk because we have no idea of the indoor air quality - no indicators.
Considering how the 'collective we' made Mode of Transmission Errors - some possibilities
a) we turned doubt in to certainty, the use of qualifiers in original work were turned into fact, eg.
'droplets have traditionally been defined as ...'
became
'droplets are defined as '
a) More doubt to certainty
Dr X et al showed that viruses can get in to the eyes, nose and mouth
was translated to
Dr X et al showed that all droplets get in via the eyes nose and mouth
b) We interpreted transmission in a 'close space' as evidence of droplets; actually it was evidence of close space respiratory transmission - not evidence for droplets
7 slides showing that neither CDC nor WHO presented evidence for the existence of droplet transmission
You may have seen this from the WHO most pandemic refs refer to it - note lack of evidence (its not in 5), and in the def or aerosols it says 'its not yet clear'
This is from the CDC which cites references showing 'outbreak evidence', 'experimental evidence' and 'aerosol dynamics'....
Only relevant outbreak reference is 101 - lets get it...
Here it is. Med students walk in to 8-bedded bays interview pts and leave. Index case (SARS) bed 11.
3 in droplet range get SARS; 4 outwith droplet range also get it. Authors conclude close = droplets but aerosols were not excluded.
CDC cites this as evidence for droplets...
