Cost-utility analysis of a one-time supervisor telephone contact at 6-weeks post-partum to prevent extended sick leave following maternity leave in The Netherlands: results of an economic evaluation alongside a randomized controlled trial

Table 3 Respective group mean costs and mean cost differences during the post-intervention period (from 6-52 weeks post-partum), and pooled totals for the first 52-weeks post-partum (including 1^st 6-weeks post-partum) based on imputed data and reported in 2006 Euros.

Components	STC*	CP*	Mean difference	Pooled^†
	Mean (S.D.)	Mean (S.D.)	(95% CI)	Mean (95% CI)
Health care sector	199 (375)	169 (326)	30 (-32; 99)	1707 (1613; 1765)
Other sectors	11 (39)	10 (51)	1 (-8; 9)	11 (8; 16)
Patient/family	273 (603)	274 (616)	-1 (-121; 127)	608 (528; 690)
Sick leave	662 (1682)	625 (1655)	37 (-252; 334)	643 (506; 821)
Work presenteeism	765 (1164)	655 (944)	109 (-66; 298)	709 (615; 804)
Total productivity loss	1427 (2297)	1281 (2084)	146 (-228; 528)	1352 (1158; 1561)
Total costs	1911 (2867)	1734 (2644)	177 (-293; 678)	3678 (3386; 3951)

* STC = Supervisor telephone contact; CP = Common Practice.
^†Pooled mean costs for health care sector and patient/family are higher than the mean group values during follow-up because the pooled means include costs during the first 6-weeks post-partum. During the first 6-weeks post-partum (i.e. pre-intervention phase), health care resource use and informal care by partner and family were high and similar between groups.
