Objective: To assess European psychiatrists' prescribing behaviour and their perceived need for access to a wide range of atypical antipsychotics for patients with schizophrenia and bipolar disorder. Methods: A blinded, internet survey of psychiatrists from the UK, Germany, Italy and the Netherlands occurred in 2007. Key inclusion criteria for psychiatrists: practising full time; practising for 5-35 years; prescribed atypical antipsychotics in prior 6 months to ≥20 patients with schizophrenia or bipolar disorder. Eligible psychiatrists selected records for four patients with schizophrenia or bipolar disorder for whom they prescribed ≥1 atypical antipsychotic since January 2004. Results: Survey response rates were: UK, 14.8% (n = 107); Germany, 9.6% (n = 104); Italy, 8.9% (n = 101) and the Netherlands, 3.7% (n = 51); 363 psychiatrists reported on 1442 patients. Psychiatrists perceived a greater difference among atypical antipsychotics as a class (mean, 5.1 on a 7-point scale [7 = 'highly differentiated']) but not selective serotonin reuptake inhibitors (mean, 3.6). On average, psychiatrists used 6.8 different atypical antipsychotics across their patients with schizophrenia and 4.4 across their patients with bipolar disorder, with 2.5 and 2.4 changes required following first-line treatment to stabilise therapy, respectively, The most common reason for switching medication was lack of efficacy. Psychiatrists reported that expected consequences for patients should access to atypical antipsychotics be restricted would include illness deterioration, non-adherence and hospitalisation. Conclusions: Although this study is limited by potential selection biases, these data suggest that European psychiatrists tailor antipsychotic medications for patients with schizophrenia or bipolar disorder according to patients' needs and specific drug attributes.
