Quantitative evaluation of reach

	No (%) of 3D reviews delivered
Practice level analysis	n=16 practices
Reach (% expected number of reviews delivered)
First review	Median 66% (range 38%–94%)
Second review	Median 47% (range 0%–93%)
Patient level analysis	n=797
Delivery of 3D nurse and GP reviews*
Two 3D reviews with both GP and nurse (full)	390 (49%)
One 3D review with both GP and nurse (partial)	205 (26%)
Other (eg, nurse review but no GP review) (partial)	31 (4%)
No 3D reviews (none)	171 (21%)

*622 (78%) patients had at least one nurse review; 599 (75%) had at least one GP review. 390 (49%) patients received a ‘full’ intervention (defined as having two reviews, with each review involving a nurse and a GP appointment which could be on the same day or different days that is, four appointments in total) in the 15 months of follow-up. 21% received no intervention.
