    Health Requirements


    At HDH/KGH we offer placement experi­ence for some of the St. Lawrence Col­lege HIM students in our Health Information Services Department. Students work closely with confidential client information in a variety of applied ways, and learn how health statistics contribute to the management of the organization and client care. The student will get “hands-on” experience applying the classification of diseases and interventions to the actual patient charts as well as experience in release of confidential patient information applying PHIPPA, Public Hospital Act and the Mental Health Act. This partnership in education has been a mutu­ally rewarding experience both for our organization and the HIM students.
