The hospital intensive care unit given me the wrong ID tag, can I take action against the hospital

As I am not licensed in your state, I cannot give you specific legal advice as to Texas state law. However, generally, even if there has been medical malpractice, without specific damages you do not have a viable claim worthy of the time and expense that would be entailed in bringing it forward. Medical malpractice claims are expensive to litigate. However, you do have an absolute right to a full and complete copy of your hospital records. You should contact the hospital records Dept. and complete the required release form and obtain your records. These records then can be reviewed by your family doctor. If a serious error has been made, you certainly could still file a complaint with the state agency which regulates the hospital or the doctors and nurses involved in your care. Filing this kind of a complaint will not get you monetary damages, but it may help prevent serious injury to some other patient in the future.
