Effects of a Patient-Provider, Collaborative, Medication-Planning Tool: A Randomized, Controlled Trial

Table 4

Patients-reported knowledge about the indications for medicines in their regimen before and after intervention: Medtable versus usual care.

	Time	Medtable	Usual care	Unadjusted intervention effect (ITT)		Adjusted intervention effect (ITT)
		Mean (SD)	Mean (SD)	OR (95% CI)	value	OR (95% CI)	value
Combined knowledge of the indication for drugs in the regimen, “what is the medicine for?”	Baseline, preintervention	0.87 (0.21)	0.87 (0.20)	1.04 (0.88, 1.23)	0.6815	1.06 (0.89, 1.27)	0.4977
	Immediate, postintervention	0.94 (0.12)	0.88 (0.19)	2.22 (1.80, 2.74)	<0.0001	2.32 (1.86, 2.88)	<0.0001
	Month 3	0.95 (0.12)	0.88 (0.19)	2.34 (1.88, 2.91)	<0.0001	2.45 (1.95, 3.09)	<0.0001
	Month 6	0.96 (0.09)	0.91 (0.17)	2.35 (1.86, 2.98)	<0.0001	2.53 (1.97, 3.25)	<0.0001

ITT: intention-to-treat analysis. Covariates used for adjustment were health literacy (REALM), Letter Comparison test, Pattern Comparison test, diabetes mellitus knowledge, diabetes self-care: diet, diabetes self-care: exercise, diabetes self-care: glucose testing, years with diabetes mellitus, Comorbidity Index, general health, age, gender, race, patient education, research site, and Medication Regimen Complexity Index.
