The sanctions which may be applied against persons who engage in the unauthorized practice of medicine are a key concern of paramedicals undertaking expanded health care service roles. If they exceed the scope of their traditional practice, they place themselves in jeopardy, not only of disciplinary action from their own professions, but also of civil and criminal liability under the medical practice statutes. These would ostensibly apply where a nurse, a midwife or another non-doctor participated in health care activities without proper authorization.
