I think you are right, I have not seen anything exactly like what you describe.
However there are a lot of sources for helpful information.
The MHRA GCP Guide 2012 has lots of information including on audits and QMS.
Obviously the HRA and NHS R & D sites with toolkits. https://www.ct-toolkit.ac.uk/routema...-consultation/
https://rdforum.nhs.uk/
https://www.hra.nhs.uk/planning-and-...ical-practice/
Its a great idea to join the Research Quality Association (www.theRQA.com) as it is an association for people like you. They have got lots of resources including virtual conferences; regional meetings; discussion forums; webinars etc. Well worth a look.
