  1. Evaluation of computer support for prescribing (CAPSULE) using simulated cases.

    Article - En anglais

    Objective 

    To evaluate the potential effect of computer support on general practitioners'prescribing, and to compare the effectiveness of three different support levels.

    Design 

    Crossover experiment with balanced block design.

    Subjects 

    Random sample of 50 general practitioners (42 agreed to participate) from 165 in a geographically defined area of Oxfordshire.

    Interventions 

    Doctors prescribed for 36 simulated cases constructed from real consultations.

    Levels of computer support were control (alphabetical list of drugs), limited support (list of preferred drugs), and full support (the same list with explanations available for suggestions).

    Main outcome measures 

    Percentage of cases where doctors ignored a cheaper, equally effective drug ; prescribing score (a measure of how closely prescriptions matched expert recommendations) ; interview to elicit doctors'views of support system.

    Results 

    Computer support significantly improved the quality of prescribing.

    Doctors ignored a cheaper, equally effective drug in a median 50% (range 25%) - 75%) of control cases, compared with 36% (8% - 67%) with limited support and 35% (0-67%) with full support (P<0.001).

    The median prescribing score rose from 6.0 units (4.2-7.0) with control support to 6.8 (5.8 to 7.7) and 6.7 (5.6 to 7.8) with limited and full support (P<0.001).

    Of 41 doctors, 36 (88%) found the system easy to use and 24 (59%) said they would be likely to use it in practice. (...)
