Defining Patient Preferences for a statin
We conducted a web-based study to describe the distribution of preferences for statin therapy across the spectrum of CVD risk. We surveyed 304 respondents aged 40-75 who had not taken a statin before. Based on their 10-year CVD risk, respondents were provided with an estimate of their absolute risk reduction and information about the risks of statins. Respondents then answered questions about their preference for a statin. We found:
· 45% of respondents reported they would definitely or probably take a statin
· As risk increased, the proportion who would take a statin increased
· A clear majority preference (>60%) for statins did not emerge until the 10-year risk was 20-50%
· For patients with a risk >10%, desire to take a stain decreased as respondents’ health literacy, subjective numeracy and knowledge scores increased.
With these findings as background, we submitted a grant to NIH/NHLBI to expand this work to clinical populations.
