Background And Objective: The aim of this study was to identify the extent to which treatment decisions for medical in-patients in three hospitals in Catalunya are supported by published evidence.
Patients And Method: In a retrospective, cross-sectional study, main diagnosis-treatment pairs (DTPs) were identified for 980 hospital discharges. The Cochrane library and MEDLINE from 1966 to 1998 were searched for systematic reviews or, in their absence, randomized controlled clinical trials (RCT) that supported the treatment given for each diagnosis.
