Translating the extraordinary scientific and technological advances from the biomedical research laboratory into actual patient care practices and other processes aimed at promoting health has been a major challenge, particularly for patients in community settings. Because of that the increased participation of clinicians from primary health care in clinical research would have a number of benefits. As experts in the delivery of clinical care in one society, they have much to contribute providing health care for patients in the whole spectrum of illnesses 1 . They are among the first to recognize changes in patients’ which come us as result of disease and conditions associated with demographic shiftings. Very often these are unexpected events such as trauma, natural disasters, pandemic infections, etc. They are also directly in contact with the policy-related matters (e.g., health consequences associated with increase in price of medications or the clinical consequences of war, such as the rapid increase in the number of individuals with prosthetic limbs and post traumatic stress syndrome) 2 . Finally, participation in clinical research would benefit clinicians from primary health care in more ways, such as: contributing the mission of medicine and improving the scientific basis for medical practice; allowing clinicians to stay with new innovations ie. the development up to-date of information systems to improve data-gathering associated with the research 3 . A major goal is the development of teams of investigators from various research disciplines, is to turm the scientific discoveries from the laboratories into treatments and strategies for patients in communities. However, even with that introduction only a small part of the community will provide participation in clinical research. The barriers for this in USA recognised from clinicians community and showed in down table 4 .
