Dream Doctors Appeal Donate Hadassah Hospital introduced Dream Doctors, also known as medical clowns, to Israel.in 2002. Today, every major hospital in Israel has medical clowns and they are empowering patients and staff in what is being termed a ‘medical revolution with a happy face’. Every dollar we raise buys one minute of a medical clown’s time at Hadassah. Each minute frees up about three and a half minutes of medical resources for its young patients. Research shows that medically-trained clowns reduce the stress levels in children, making it easier for medical staff to provide their services, which results in a shorter hospital stay for the children.
