Visit some local hospitals or private medical practices and ask if they have a physician willing to let you shadow them. Let them know you're interested in the career and wish to see what a physician does during their workday. Some places may not allow you to shadow, due to HIPAA privacy laws, but many physicians are willing to let you observe them. If you are told no physician can let you observe at that location, ask if they know another hospital that has a shadowing program.
Meet all of the requirements established in the location where the physician works. Such requirements may include getting a tuberculosis shot or Hepatitis C shot. You also may have to pass a background check or get CPR certified. Once you meet all of the establishment's requirements, set up a date for orientation. Don't arrive late to meet the physician. If your schedule changes, let the physician know as soon as possible.
Bring a small notebook and a writing utensil with you. Not only should you observe what the physician does, you should write it down so you can later inform medical schools of procedures you saw while observing. Also take note of the relationship between physicians, their patients and other medical professionals.
Remain respectful to both patients and professionals. If the patient is uncomfortable with you being in the room, politely excuse yourself and wait until the physician is done seeing the patient. If the patient allows you to remain in the room, thank them. Don't ask questions about procedures or terminology while the patient is being seen; wait until you leave the room.
Thank the physician for his or her time when you're finished shadowing. Though not necessary, you could send them a formal thank you card in the mail.
