Cost-effectiveness of the 3D approach from an NHS and personal social services perspective

	Usual care mean (SE) n=749	Intervention mean (SE) n=797	Incremental difference (95% CI)
Costs (£)
Unadjusted costs from the NHS/PSS perspective	6032 (362)	6124 (317)
Adjusted costs from the NHS/PSS perspective	6014 (343)	6140 (333)	126 (−739 to 991)
Outcomes
Unadjusted QALYs over 15 months of follow-up	0.651 (0.013)	0.691 (0.012)
Adjusted QALYs over 15 months of follow-up	0.668 (0.006)	0.675 (0.006)	0.007 (−0.009 to 0.023)
Cost-effectiveness statistics
ICER: £18 499
Net monetary benefit at £20 000 (95%CI): £10 (−956 to 977)

Net monetary benefit at £30 000 (95%CI): £78 (−974 to 1130).

Cost estimates were adjusted for randomisation variables; QALY estimates were adjusted for randomisation variables and baseline utility.

CI, confidence interval; ICER, incremental cost-effectiveness ratio; NHS, National Health Service; PSS, personal social services; QALY, quality-adjusted life year; SE, standard error.
