Improving clinical decision support tools - challenges and a way forward.

Would you prescribe a drug without regulatory approval, for which the safety and efficacy are unknown? Unlikely. Would you use a clinical practice guideline that is not endorsed by a peak body, with no accessible evidence for its recommendations and with its authorship unknown? Unlikely. Do you currently use decision support tools in your prescribing software that have not been evaluated or accredited, with unknown or variable quality and reliability? Very likely.
