Editors' Introduction: Why is Revitalizing Clinical Research So Important, Yet So Difficult?

We believe that support for academic clinical research has greatly declined in recent decades. Here we discuss our views on why this has happened. We define clinical or patient-oriented research as limited to the study of human beings or populations of individuals, and argue that its eclipse in favor of basic and "translational" research is the result of inappropriate conceptual paradigms or "models" for medical advances. We believe that medical history shows that the "bench-to-bedside" model is inadequate to explain most recent progress and that clinical advances themselves often lead to new basic research. Discussion of alternate conceptual frameworks for biomedical research should help lead to changes in funding and organizational structures that might finally revitalize clinical research
