New York State Department of Health Code, Section 405, also known as the Libby Zion Law, is a regulation that limits the amount of resident physicians' work in New York State hospitals to roughly 80 hours per week. The law was named after Libby Zion, who died in 1984 at the age of 18 under the care of what her father believed to be overworked resident physicians and intern physicians. In July 2003, the Accreditation Council for Graduate Medical Education adopted similar regulations for all accredited medical training institutions in the United States.
