Medical Assistant - Scope of Practice

Scope of Practice

Medical assistants must work under a physician's direct supervision when performing clinical duties delegated by the physician. In the US, some states allow medical assistants to perform more advanced procedures, such as giving injections or taking X-rays, after passing a test or taking a course. In some states, (e.g., Utah), there is little if any distinction between a surgeon's assistant and a medical assistant. Both may assist the physician or surgeon in any capacity that the supervising physician deems appropriate, including directly supervised incisions, administering local anesthesia, infusing tumescent anesthesia, aspiration of hypodermic fat, ablative laser dermal resurfacing and many other cosmetic procedures.

Medical assistants perform many administrative duties, including answering telephones, greeting patients, updating and filing patients’ medical records, filling out insurance forms, handling correspondence, scheduling appointments, arranging for hospital admission and laboratory services, and handling billing and book keeping. Duties vary according to laws of the jurisdiction and may include taking medical histories and recording vital signs, explaining treatment procedures to patients, preparing patients for examination, and assisting during diagnostic examinations. Medical assistants collect and prepare laboratory specimens or perform basic laboratory tests on the premises, dispose of contaminated supplies, and sterilize medical instruments. They instruct patients about medications and special diets, prepare and administer medications as directed, authorize drug refills as directed, telephone prescriptions to a pharmacy, draw blood, prepare patients for X-rays, take electrocardiograms, remove sutures, and change dressings. They also facilitate communication between the patient and other health care professionals. According to the United States Department of Labor, job prospects for medical assistants are excellent since medical assisting is predicted to be one of the nation's fastest growing occupations through 2018.
