The law takes into account such matters as differences in various schools or systems of medicine, the state of medical acumen and knowledge, the established mode of practice, the locality, and conditions of practice. To reach a logical standard for physicians, and especially for that segment of the profession designated as "the general practitioner," various requirements are recognized by the law. Some courts insist that the degree of care and skill shall be commensurate with the advanced state of the science at the time of rendition of the service. This concept of the amount or degree of scientific medicine must be modified to include the knowledge of the patient's education in "lay medicine."
