From the work I have been associated with in Africa (OpenMRS.org) there is a commandment. "To improved care you have to bea able to measure it." This cannot be done without the relevant data. Also from Dr. Mark Smith of the Californian Health care Foundation (no profit) when discussing opinions in health. "That we must remove ourselves from the ‘unscientific, non data driven personal recommendations’ for care." [Health IT: Hope, Hype, and How to Avoid the Road to Hell. AMIA 2009, San Fran. ] Terry Hannan (I think any senior clincian of value should be able to stand and be recognised if they want to make challenging statements.).
