title: Views on treatment necessity, harm, and benefits in patients using statins.
abstract: BACKGROUND
  Patients with dyslipidemia and high overall risk of ischemic heart disease are those most likely to benefit from treatment with statins. The objective of this study was to investigate patients' views of the necessity, harm, and expected benefits of their statin treatment, as well as factors associated with these treatment beliefs. One main objective was to investigate whether cardiovascular risk level and previous coronary heart disease affect the way patients view these different aspects of their medication.
  
  
  METHODS
  A total of 829 statin users were recruited while visiting a pharmacy to collect their statin medication (response rate, 69.4%). Patients returned a questionnaire assessing their medical history, concurrent risk status, social demographic factors, as well as their views and expectations regarding their statin treatment.
  
  
  RESULTS
  Previous ischemic heart disease, or high risk of such disease, was not associated with a more favorable notion on statin treatment. Having an internal health locus of control as well as being satisfied with the physician's treatment explanation were factors associated with more positive views on expected treatment effect. The views on necessity, harm, and treatment benefit were closely associated with each other.
  
  
  CONCLUSIONS
  The main findings in this study suggest that cardiovascular risk level and previous coronary heart disease are not associated with the way patients value potential benefits of statin treatment. Patients' views of the treatment's necessity, harm, and benefits do not seem to be independent dimensions of patient beliefs but rather represent one overall question: is this good for me?
