Bear in mind I've never worked in the investigatory phase, so only really know second hand. Also I work with another regulator and have no direct experience of the GMC/MPTS, so to an extent I'm assuming.
But the way it works where I am is:
- Initial complaint comes in
- Someone non-clinical looks at it and decides if it could be something they should investigate. So, if the complaint is "I didn't like the colour of the waiting room" or "The coffee was awful" (both genuine examples) it will be closed at that stage with a polite letter to the complainant. If it's something of substance an investigation will be started.
- The investigation happens. Depending on what the concern is, this may mean requesting patient notes, and taking statements from them. It may be getting an expert to give their opinion on what happened. It may mean looking through social media. It will involve asking the doctor for their side.
- Someone rather more senior looks at all that info to decide if it should go forward.
- If they decide it should, it goes to an investigating committee to make a formal decision about whether to bring it to a hearing, whether to just issue a warning note, or whether to close it. A warning note is kept on record, will be taken account of in future complaints, and can be published publically.
- If appropriate, a formal hearing is booked.
- Investigatiosn continue. More statements may be taken. Further experts instructed. There's a fair bit of case management to keep things moving. So the GMC (the prosecution) will be told they have to get these papers to the defence by that dates, and the defence will be told they have to indicate what will be admitted and which witnesses will come by this date. There is a team of people keeping that on track. In my head they have cattle prods. They probably don't, but they probably should.
- The hearing happens.
I know some of the regulators are moving to a system where, if it's clinical issues which can be addressed through training, and they're admitted then the professional agrees undertakings. So, instead of a hearing, the professional says "I'm crap at X, Y, Z. I promise to do more training and work under supervision." That gets to the same likely result quicker, saving everyone time and grief. That's then monitored and moves to a hearing if it doesn't work out.
In this case, a couple of things might happen. If he's struck off, I suspect the complaints will go in the round file. If he's suspended then there will almost inevitably be a review. I don't know, in that case, if they'd start a new hearing or simply use that material at a review to argue he should stay suspended. Tactical decision, I would guess, but who makes that decision and how I don't know.
