  Clinical decision support systems have been developed to help physicians to
take clinical guidelines into account during consultations. The ASTI critiquing
module is one such systems; it provides the physician with automatic criticisms
when a drug prescription does not follow the guidelines. It was initially
developed for hypertension and type 2 diabetes, but is designed to be generic
enough for application to all chronic diseases. We present here the results of
usability and satisfaction evaluations for the ASTI critiquing module, obtained
with GPs for a newly implemented guideline concerning dyslipaemia, and we
discuss the lessons learnt and the difficulties encountered when building a
generic DSS for critiquing physicians' prescriptions.
