A physician needs to complete at least one year of training in a certified residency program and must pass all three parts of the USMLE to become qualified to apply for a medical license. Residency entails a 3-7 year minimum commitment of training to attain clinical skills and board eligibility. Residency is highly sought after, and there are hundreds of candidates who do not match each year.
If you answered yes to any of the above questions, then you need to stay in your residency to become qualified.
Your discouragement is understandable, but dropping out will not help you get where you want to go.
If you answered no to all of the above questions, then move on to the following questions.
If you answered yes to that question, then you need to develop good relationships with your program directors and transfer into a different residency.
You deserve to practice the specialty you want to- and even if you waste a few years of training to get the specialty you want- you will find the extra training well worth it.
If you answered no to all of the questions so far, then move on to the next question.
I am sure you don't want to hear this, but, completing your residency actually puts you on par with non-MDs who are qualified in their own areas.
If you have still answered no to every question so far, then move on to the next question.
If you answered yes, then leaving residency is probably in your best interest. Residency, board eligibility and board certification will not help you attain these types of positions any more than just having a graduate degree. In fact, this is the only instance in which you will waste time professionally by remaining in your residency. But, be aware that your medical school and your residency will not be helpful in getting you the job you are looking for, and that you will have to start at the bottom and work your way up.
