The factors that affect physicians' prescribing remain unclear. Although previous reports suggest that prescription decisions are associated with various clinical situation, most of these studies analyzed simulated patient models rather than actual clinical practice. Here, we retrospectively analyzed actual cases of statin prescription for hyperlipidemia at Tohoku University Hospital between Apr 1, 2004 and Mar 31, 2008. Twelve physicians (6 cardiologists, 3 nephrologist, and 3 diabetologist) made decisions on whether to prescribe statins to 187 patients in 788 visits. As expected, cardiologists started prescribing statins at significantly lower serum total cholesterol levels than other specialists (221.7mg/dL vs. 244.7mg/dL, P<0.05). Interestingly, the total cholesterol levels that triggered prescribing differed significantly among cardiologists (p<0.05). These results suggested that prescription decisions differed not only among specialties but also among individuals.
