Medication discrepancies and ADEs caused by medication discrepancies in hospitalized nursing home patients, stratified by VA / non-VA group.

	VA	Non-VA	Unadjusted difference	Adjusted difference*
Medication discrepancies† (mean (s.d.))	2.62 (2.16)	2.55 (2.18)	Diff = 0.07 (−0.26 to 0.42)	Diff = 0.02 (−0.81 to 0.85)
High-risk medication discrepancies† (mean (s.d.))	0.96 (1.07)	0.75 (0.92)	Diff = 0.21 (0.05 to 0.38) §	Diff = −0.18 (−0.22 to 0.58)
ADE caused by a medication discrepancy‡ (% of hospitalization episodes)	18.1%	21.5%	OR = 0.83 (0.44 to 1.59)	OR = 0.96 (0.18 to 5.01)
(Subsample n=127 VA; n=177 non-VA)
