InterQual Development Process

Comprehensive, structured research for reliable results

As the quest for transparency in healthcare becomes more urgent, healthcare organizations are finding that InterQual clinical content offers a common foundation that enables greater trust and collaboration when it comes to decisions about appropriateness of care.

InterQual content is by far the most widely-used evidence-based clinical decision support for care management because of its sound clinical logic that rests on our rigorous, comprehensive development cycle. Refined and proven over 30 years, this development cycle combines systematic, critical assessment of the medical literature by our highly trained clinical development team with feedback from our InterQual Clinical Panel of 1,100 experts.

Because of our exacting development process, you will find that InterQual criteria have a level of credibility and integrity that cannot be found in other products.
