Table 5. Facilitators to IDE post-implementation, as identified by patients and staff.

Post implementation facilitators	Theory domains	Patient	Staff
Positive outcomes of participating in IDE	Beliefs about consequences, Reinforcement, Emotion	“I used to struggle with my blood pressure, towards the end it always used to drop, I wondered if the exercise would help to stabilise it and it did, so that was a plus” (56 year old male Asian patient)	Last year [before the cycling] the dialysis patients tended to be unmotivated, depressed. I’ve seen them cycling and they are more cheerful, happy, its helping them” (Nurse)
		“I can now walk up to the village which is about half a mile and I feel it’s the cycling that’s helped” (75 year old female White British patient)	“As a doctor working on a dialysis unit it can sometimes be fairly bleak in that dialysis is a very good treatment for keeping people alive but doesn’t always enable people to live. I think if there is a treatment that makes [patients] feel better that makes you feel a whole lot better about what you do to people.” (Consultant Nephrologist).
		“Because of the exercise I can sleep better. I can sleep 5–6 hours at a time” (67 year old male Asian patient)	“I am surprised at a …lady I thought wouldn’t do it but she did. I needed to be proven wrong because we are not always right” (Senior nurse)
Collaboration and teamwork	Social influences, Behavioural regulation, Social/professional role and identity		“Even [nurse in charge] will get the bikes out …you have to have her on board, and the two deputies.” (Dialysis Assistant)
			“Because the [exercise professional] has taught [the patients] we just set the bike up for them. Patients will tell us how to fill the paperwork in…they will say come back in however many minutes or if I have a problem I will call you…” (Nurse)
