In every state in the US licensed health care professionals (doctors, registered nurses, LPN, etc.) are required to complete professional education development classes (continuing education) in order to be renew their professional license. This is as it should be. What should be considered is one uniform set of standards that would apply to medical professionals equally in every state.
Yes, those in the health professions should be required by law to take continuing education classes, because the health profession always changes. There are new standards for treatment. There are new technologies available. A professional should stay current so that they can give the best care possible to their patients.
Health care professionals should be required to participate in continuing education classes, with financial help from their employer and/or Federal grants. Medicine and medical treatments continue to undergo changes. Things that work are improved as much as possible and things that do not work are discarded. Advances in medicine require learning in a classroom setting.
I believe those in the health professions should be required by law to take continuing education classes. Doctors learn a great deal while in medical school but there are always changes in health care, updates, and research to stay up to date on. I have spoke with many doctors who are unaware of recent advancements and clearly don't take the time to read recent studies. These people need to stay up to date.
