Medical

It would be helpful if you could provide a bit more detail. I'm assuming that you are interested in potential legal regulatory or malpractice issues. Each state has specific laws and regulations that address what non- medical doctors are authorized to do in connection with patients. In Texas, such laws cover nurses and physicians assistants. From a liability standpoint, these statutes and regulations provide the starting point for such an analysis. Each situation, such as the one posed, requires a facts-and-circumstances analysis. Among the considerations that may be involved are (1) was the advice incorrect? (2) was the physician aware this was occurring or not? (3) was the advice conditioned?, etc.

Since the facts of each case are different, it is important to seek out qualified counsel with whom information can be shared and assessed under an attorney-client privilege so that competent and tailored advice can be provided.
