For Referring Physicians

Referring Your Patients to Clinical Studies

Welcome to the NIH Clinical Center. This Web site is for a unique cadre of "partners in discovery"—those of you who refer or plan to refer patients to clinical research protocols at NIH's clinical research hospital in Bethesda, Maryland.

As you know, clinical research and medical discovery depend on the participation of patient volunteers. Many patient volunteers become involved in clinical research because their personal physicians have discussed the option with them.

We appreciate your commitment to clinical research and are committed to strengthening our collaborations with you. We welcome your feedback about this Web site and about how to improve our communications with you. Please let us hear from you.
