Abstract
Low rates of statin prescribing have been noted in several major studies of patients with schizophrenia and the aim of this study was to investigate clinicians’ attitudes to prescribing statins to different patient groups. The general practitioners (GPs) in Dumfries and Calloway were randomized into two groups. They received an email invitation to a web-based survey. The survey asked for treatment recommendation for three patient vignettes, each with a 10-year cardiovascular risk of 20%. In one group descriptions of the patient included type 1 diabetes, epilepsy and unemployed and in the other group these were replaced by type 2 diabetes, schizophrenia and retired. The questionnaires had no other differences. After three email invites, 53 questionnaires were completed (40% of a potential 133 participants). Statin therapy was recommended by 88% and 85% of respondents for patients with type 1 and type 2 diabetes, respectively; by 37% of respondents for patients with schizophrenia and 31% for patients with epilepsy; by 33% of respondents for retired patients and 23% of respondents for patients who are unemployed. This study demonstrates under-prescribing of statins. This was not worse for patients with schizophrenia as compared with patients with epilepsy. This suggests that the low rates of treatment of metabolic risk factors in patients with schizophrenia are not the result of clinician bias when compared with patients with epilepsy. Clinician bias, however, may reduce the chances of an unemployed patient receiving statin treatment.
