Concept: Interqual Criteria
Last Updated: 1999-11-16
Level of Care Criteria
InterQual Criteria are set of measurable, clinical indicators, as well as diagnostic and therapeutic services, that reflect a patient's need for hospitalization. Rather than being based on diagnosis, they consider the level of illness of the patient and the services required; thus they serve as the criteria for all acute hospital care, regardless of the location or size of the hospital.
Intensity of Service
Severity of Illness
- Discharge Screens
The criteria are grouped into 14 body systems, and there are 3 sets of criteria for each body system:
Intensity Severity Discharge (ISD) Level of Care Criteria are used to determine the appropriateness of admission, continued services, and discharge, across the continuum of care. ISD uses objective, clinical indicators to determine the proper level of care, based on the patient's severity of illness and service requirements, and to suggest an appropriate care setting. Healthcare organizations around the world use ISD to stop overutilization, guard against underutilization, and manage financial risk via appropriate clinical means. ISD is intended to supplement and support the physician's own knowledge base.
InterQual Clinical Decision Support Criteria help you ensure both the appropriateness of medical services and effective cost control. They are a proven demand management tool. Focused on clinical appropriateness, InterQual Criteria distill best medical practices into practical tools for guiding, monitoring and documenting point-of-care decisions.
