RTB, presumably the reverse isolation would only be worth doing for CEV patients anyway?
It would probably be the best approach.
To highlight some of the practical barriers i think you need to reflect on just how bad the existing staff and hospital facilities are a real issue. A hospital with buildings in some level of disrepair is going to have infection control issues anyway - we know that research into SARS and covid have both identified infection problems via ventilation shafts and shared sewers. My local hospital is in a dreadful state. They been trying to apply for a brand new site and building for a number of years because of the cost of upkeep for the current building and how its really no longer fit for purpose. Its far from the only hospital with similar issues.
BIL (who works in a completely different hospital) was explaining how one particular department (non covid) would need to be split into two areas to be compliant with new hospital rules coming in. It was a small specialist unit - with a limited specialist staff. You can't have hot staff working cold areas. So he had no idea how they could manage that. He also said that the building itself was problematic because it had two bays but no doors between them. And they needed to maintain male and female areas for patient dignity.
So options on the table would have to be more mixed wards. And installing new doors somehow to try and put in infection control - but he did not know how you would do that. Or where the money would come from. Infection control on wards split in the middle was proving a nightmare if you didn't have this type of permanent barrier as part of it.
And that also didn't address the staffing issue nor the toilet issue that arose from splitting the department.
(and ignores other more complex issues with shared ventilation and sewers completely)
I got the impression he very much thought under the circumstances it was at the point where it was an exercise in shuffling the deck chairs on the titanic rather than anything meaningful because of the degree to which splitting staff who were already short handed was affecting patient care negatively anyway.
You have to ask the crucial rather cold question about whether you end up losing more patients setting up split specialities or just not worrying about infection control because its flogging a dead horse now.
I definitely think you have to consider whether certain conditions are particularly at risk - so yeah immunocompromised patients perhaps do need a different approach to at least attempt isolation for covid negative patients. But not necessarily a blanket approach for an entire hospital because its just not practical nor possible.
