Yes, I imagine that's what happens in reality. I think the NICE guideline is talking about the DAFNE-style more lengthy education, which I could imagine could be a bit much initially.
Regrettably, not in my reality.
I spent 14 days in hospital, after my total panc'y. The first 4 days I was essentially between Theatre, ICU and on a ward sleeping; fair enough. For the next 6 days I was connected to a machine that was managing my insulin, steadily recovering and increasing my daily walking regime as I regained strength: again all pretty sensible and during this period I was given a basic "welcome to DM pack": goodies packaged as a present from 4-SURE. Commercial interests clearly prevailed; they were (are?) the approved supplier throughout that Oxford Trust, but not in Bucks a few miles away. The delightful D Nurse who delivered these was clearly busy, her beeper summoned her away twice and inevitably very little information was conveyed then. I read everything provided; carb counting was not included.
On day 10 or 11, I was taken off the insulin machine and started on MDI. A ward nurse arrived with finger pricker, rook a reading which wasn't shared and returned a couple of hours later with insulun; she had been told what my dose was, had no explanation for why that amount, didn't explain the distinction between basal and bolus but happily said it would all be explained in due course.
This continued for 24 hrs and I eventually reached out to the Consultant who had seen me on a daily basis and asked for more info, which he undertook to get sorted. The delightful D nurse returned, apologised for not returning earlier but alas was covering several wards, got beeped and went away again. Another opportunity missed. On Day 12 the Consultant during his morning rounds said I could go home that day - I pointed out that I'd still not had any instruction about managing my D, had not even been allowed to touch an insulin pen, never mind finger prick and could that all happen before I was discharged. Day 13 arrived, late in that day the truly delightful D nurse returned explained about injection techniques, mentioned carb counting but told me I'd be given more info and instruction, chatted helpfully, got beeped and left.
Day 14, I was discharged. Not really any wiser. I was willing to learn, but the Hospital clearly didn't have the resources (personal or literature) for in-patients, to help with a sensible pre-discarge briefing. I didn't know any different, so didn't politely pester enough. If I had understood then what I now know I feel that, in hindsight, this aspect could have been managed so much better.
Perhaps a distraction from this bit of the "D and running" thread: I'd been visited almost daily by the HPB dietician and asked her about how to find out carb info. During those conversations she 'rummaged' in to some part of the hospital admin and found the carb content for most of the hosp meals; it was a a little out of date, certain meals ere no longer covered. Knowing something about service supply contracts to large organisations, I suggested all of the nutritional and dietary detail would exist somewhere for all aspects of catering srvices; she found a copy, some 40 pages thick and had no idea this had existed. There were 7 or 8 dieticians within the hospital, each working directly in support of their specialisation Consultants, none co-ordinated by an overall Dietectic 'supremo' and these 7 or 8 dieticians knew each other superficially, but had no remit to confer periodically, nor exchange best practice ideas, etc. Disappointing, but not so surprising to me (seen this sort of lost opportunity elsewhere; good people too busy to look around at the wider picture). I asked the Ward Administrator if she ever saw the 40 page nutrition document, which was updated and republished monthly; she went to her desk area, returned with a lever arch file and proudly showed me the ward copy, complete with covering letter, filed under a completely irrelevant title. She filed this every month, no one saw it and over time time no-one knew it existed. It's title included words like "Nutritional Detail .. Service Supply to Oxford NHS Trust..." and not a hint of whatever it was filed under. I got the opportunity to show this to a Matron, who recognised that the Ward, Hospital and Trust could do better; whether they did, I have no idea. I was discharged the next day with a 3 page D supplement from the D nurse including my ratios and fixed doses, but no mention of carb counting nor the need to attend a course such as DAFNE, but a small print suggestion to try BERTIE on line.
On Day 15, I got a face to face with my new DSN in a Bucks Hospital. She was happy to leave me on fixed MDI, stating it was too early for me to bother with carb counting; but to her credit she scrutinised a photo of my 4-SURE logbook sent by email fortnightly and adjusted my doses - all done from a distance (Covid lock down meant we didn't meet FtoF again for over 12 months). After 8 months and by now thoroughly cheesed off with my erratic BG, I found this forum and a suggestion to look at Gary Scheiner's "Think Like Pancreas". Still learning, still trying to secure a DAFNE course.
My conclusion: NICE have tried to provide a framework, including let things settle and leave in depth training for 6 months; not sure if that's correct but it's a start. In practice Trusts are overwhelmed by NICE dictats and don't (can't) keep up with the reading, never mind the implementation; these sorts of things can take years to work there way through the bureaucracy. Not sure how this overarching problem can be changed in the current status quo; Trusts need Chief Executives at the top of their game, able to see beyond the political and financial contradictions, able to recognise the lower level pressures as well as the immediate challenges such as bed shortages, Theatre priorities and media perceptions.
