Would provision of evidence always make a meaningful difference in care? This was examined in 2 studies as regards
anti-hypertensive medications in China.


To compare the effect of evidence-based counselling on public’s willingness to pay out of pocket for antihypertensive drugs with that on actual drug-taking behavior of insured patients.


A survey was conducted for people’s willingness to pay for anti-hypertensive drugs before and after counselling. A randomized controlled trial was conducted in mild hypertensive patients to evaluate the impact of counselling on their drug-taking behaviors in a setting where these medications are covered by insurance. The counselling include the 5-year CVD risk, number needed to treat (NNT) for preventing one CVD event in 5 years and information on costs and harms.


1080 residents were included in the survey and 210 patients in the trial. The willingness to pay out of pocket for
antihypertensive drugs dropped from 95% before counselling to 23% immediately after counselling. The trial showed, after six months of counseling, both the rate of medication use and of good adherence showed little or moderate
difference between the counselling and control groups (medication use: 65.0% vs. 57.9%, P=0.290; good adherence: 43.7% vs. 40.2%, =0.607).


There is a sharp contrast in the effect of evidence on people’s willingness to pay for and actual use of anti-hypertensive
medications. The payment method is likely to be the most important determinant for use of medications. These findings raised a question whether insurance policies and clinical guidelines have faithfully reflected patients’ opinions
and challenged the usefulness of informed decision-making in patients with comprehensive insurance to cover the medication.
