Much of my work involves explaining and trying to apply the principles of EBM and EBHC, often to people who have been puzzled and even irritated by what they had thought EBM and EBHC implied about their current and past practice. This definition requires that valid, relevant evidence should be considered alongside other relevant factors in the decision making process. I have no wish to exclude any particular type of information as long as an appraisal is made of its validity and relevance and the information is given 'due weight' - neither more nor less. Other things follow from this definition, not least that the concept of EBHC is not new - it's what most people I know have been trying to practice all their working lives. I have been using this definition for a year or so now.
People seem to find it useful and non-threatening.
I would value the thoughts and any suggestions for improving it from readers of Bandolier .
