Standard Hospital Admission Criteria ( SHAC) is a 20 page guide on the admission criteria from the emergency dept. It is the only guide of this kind.This book is not intended to substitute for a fundamental understanding of medical principles, nor is it meant to supersede the clinical judgment of the individual practitioner. Standard Hospital Admission Criteria ( SHAC) is meant to guide physicians, practitioners, nurses, case managers, and other health care providers through the entanglement of documentation nuance required to not only ensure proper payment to providers and hospitals by insurers, but to prevent deleterious financial impact to the patient as a result of inadequate documentation by the provider in support of hospital admission.
