NIH Roadmap 3: Re-engineering the Clinical Research Enterprise • R.A. Harrington, M.D., Duke Research Institute (2005) : g , , ( ) – “One of the greatest inefficiencies of the current model of clinical research in our country is the lack of a sustaining infrastructure (which includes shared t i i i f t t ( hi h i l d h d resources, common data standards, and effective use of information technology among researchers), as well as the lack of a convenient forum to share best practices and learn from one another’s mistakes and successes” successes .
