All physicians make use of the results of medical research in their clinical practice. To maintain their competence, physicians must keep up with the current research in their area of practice through Continuing Medical Education/ Continuing Professional Development programs, medical journals and interaction with knowledgeable colleagues. Even if they do not engage in research themselves, physicians must know how to interpret the results of research and apply them to their patients. Thus, a basic familiarity with research methods is essential for competent medical practice.
The best way to gain this familiarity is to take part in a research project, either as a medical student or following qualification. The most common method of research for practicing physicians is the clinical trial. Before a new drug can be approved by government mandated regulatory authorities, it must undergo extensive testing for safety and efficacy. The process begins with laboratory studies followed by testing on animals. If this proves promising, the four steps, or phases, of clinical research, are next.
