CQF Ruler
The Clinical Quality Framework (CQF) Ruler is a collection of plugins built for the HAPI Fast Healthcare Interoperability Resources® (FHIR®) Java Persistence API (JPA) server that brings the FHIR Clinical Reasoning Module to life. It enables healthcare organizations and developers to process electronic clinical quality measures (eCQMs), evaluate decision logic, and apply clinical rules in real time. Beyond quality measurement, the CQF Ruler acts as a central repository for knowledge artifacts, such as care guidelines and decision support rules, and serves as a clinical decision support service that can provide actionable recommendations at the point of care. By combining measure processing, knowledge management, and decision support, the CQF Ruler helps make quality reporting and evidence-based care more efficient, consistent, and interoperable across FHIR-enabled systems.
