_Unlicensed Practitioner Causing Death Guilty of Manslaughter._—Since the adoption by most civilized states and countries of the salutary practice of regulating by statute the practice of medicine and surgery, and forbidding persons not duly licensed from practising, and making it a misdemeanor to violate any of these statutes, it is clear that any person not having the requisite medical education and a license, who attempted to administer drugs and medicines or to perform operations, and through want of ordinary knowledge and skill caused the death of another, would be held guilty of manslaughter, because he brought about the death while he himself was engaged in a violation of the law. In some states where no discrimination in this respect is made between misdemeanors and felonies, the crime would be murder, punishable by death; and it has always been the law that an empiric or quack holding himself out as a regular physician is bound to have and exhibit the degree of skill and care which he professes, and will be strictly held to the standard of skill of educated and licensed medical men.[194] As to the legal meaning of the term “ordinary care and skill,” and the rules of evidence applicable in cases of malpractice, a full discussion will be had below, when considering the subject of civil liability for malpractice. CIVIL LIABILITY FOR MALPRACTICE. Any person holding himself out to be a physician or surgeon, or any physician or surgeon, who is guilty of malpractice, is liable for damages, to be recovered in a civil action, instituted by the person injured, or by those having a legal right to such person’s services. This is so whether the injured person actually employed the defendant to prescribe or treat him, or not. The liability flows out of the relationship, without regard to the element of employment, and it may result from negligence in treatment, or in prescribing, or in giving information and instructions to the patient as to how to take care of himself when under treatment. The rules of law applicable to the duties of a physician to his patient are stated and the authorities supporting them cited in Chapter IV. of this work.[195]
