The Statin Choice decision aid in primary care: a randomized trial.
OBJECTIVE
To assess the impact of a decision aid on perceived risk of heart attacks and medication adherence among urban primary care patients with diabetes.


METHODS
We randomly allocated 150 patients with diabetes to participate in a usual primary care visit either with or without the Statin Choice tool. Participants completed a questionnaire at baseline and telephone follow-up at 3 and 6 months.


RESULTS
Intervention patients were more likely to accurately perceive their underlying risk for a heart attack without taking a statin (OR: 1.9, CI: 1.0-3.8) and with taking a statin (OR: 1.4, CI: 0.7-2.8); a decline in risk overestimation among patients receiving the decision aid accounts for this finding. There was no difference in statin adherence at 3 or 6 months.


CONCLUSIONS
A decision aid about using statins to reduce coronary risk among patients with diabetes improved risk communication, beliefs, and decisional conflict, but did not improve adherence to statins.


CONCLUSIONS
Decision aid enhanced communication about the risks and benefits of statins improved patient risk perceptions but did not alter adherence among patients with diabetes.
