Patients' self-estimated likelihood of taking a statin as prescribed after different types of prognostic information
1Division of Cardiology, Faculty of Medicine, Oslo University Hospital and Oslo University, Trondheimsveien 235, 0514 Oslo, Norway.
Background:
Statins are frequently used in cardiovascular prevention, however medication adherence is suboptimal.
Aims:
To examine if different types of prognostic information associated with prescription of a statin by physicians, can influence the self-estimated likelihood of taking the drug as prescribed, and to investigate whether patients want this type of information.
Methods:
A survey was performed in 313 patients diagnosed with CVD. Patients were presented to facts with relative risk reduction and absolute risk reduction figures associated with the use of a statin and the self-estimated likelihood of taking the drug as prescribed was registered after each given fact.
Results:
Self-estimated likelihood of taking the statin as prescribed was highest when the cardiologist recommended the drug without presenting absolute and relative risk reduction figures. Presenting relative risk reduction figures for the patients gave significantly higher self-estimated likelihood to take the statin as prescribed compared to giving the patients absolute risk reduction figures (p<0.001). A vast majority of the patients (84%) wanted to achieve information about risk reduction associated with the statin treatment.
Conclusion:
The patients wanted information about the CV risk reduction associated with the prescribed statin; however, the best self-estimated medication adherence was achieved when the cardiologist recommended the drug without presenting risk reduction figures.

There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
