As set forth in Section 4521 of the code, gross negligence is deemed unprofessional conduct and is grounds for disciplinary action. As used in Section 4521 “gross negligence” means a substantial departure from the standard of care which, under similar circumstances, would have ordinarily been exercised by a competent licensed psychiatric technician, and which has or could have resulted in harm to the consumer. An exercise of so slight a degree of care as to justify the belief that there was a conscious disregard or indifference for the health, safety, or welfare of the consumer shall be considered a substantial departure from the above standard care.
