Helping Patients With Type 2 Diabetes Mellitus Make Treatment Decisions

Results: Patients favored using the decision aid (odds ratio [OR], 2.8; 95% confidence interval [CI], 1.2-6.9); patients who received the decision aid (n=52) knew more (difference, 2.4 of 9 points; 95% CI, 1.5-3.3), had better estimated cardiovascular risk (OR, 22.4; 95% CI, 5.985.6) and potential absolute risk reduction with statin drugs (OR, 6.7; 95% CI, 2.2-19.7), and had less decisional conflict (difference, �10.6; 95% CI, �15.4 to �5.9 on a 100point scale) than did patients in the control group (n=46). Of 33 patients in the intervention group taking statin drugs at 3 months, 2 reported missing 1 dose or more in the last week compared with 6 of 29 patients in the control group taking statin drugs (OR, 3.4; 95% CI, 1.5-7.5). Conclusions: A decision aid enhanced decision making about statin drugs and may have favorably affected drug adherence. Trial Registration: clinicaltrials.gov Identifier: NCT00217061
