BACKGROUND: Americans see clinical research as important, with over 15 million American residents participating in NIH-sponsored studies in 2008 and growing yearly. METHODS: Documents reporting NIH supported Clinical Research projects were reviewed. RESULTS: When compared with other studies, the number of interventional Phase III and Phase IV trials have decreased from 20% to 4.4% from 1994-2008. CONCLUSIONS: This finding most likely has occurred for several reasons. One reason is that the physician lacks an infrastructure for designing and carrying out trials. This lack is because of an absence of a coordinated effort to train clinical trialists. It is clear that the Nation needs a more purposeful approach to developing and maintaining the infrastructure for designing and conducting clinical trials. Building it de novo trial by trial is profoundly inefficient, to say nothing about time consuming and error prone.
