Introducing Hermes: Executing Clinical Quality Language (CQL) at over 66 Million Resources per Second (inexpensively)

TL;DR

Hermes is a new high-performance engine capable of executing Clinical Quality Language (CQL) queries at over 66 million resources per second, addressing the need for scalable healthcare decision support systems.

Contribution

This paper introduces Hermes, the fastest commercial CQL execution engine, significantly improving scalability and performance in healthcare data processing.

Findings

Hermes executes over 66 million resources per second.

Hermes outperforms existing CQL engines in speed.

The engine is cost-effective for large-scale healthcare applications.

Abstract

Clinical Quality Language (CQL) has emerged as a standard for rule representation in Clinical Decision Support (CDS) and Electronic Clinical Quality Measurement (eCQM) in healthcare. While open-source reference implementations and a few commercial engines exist, there is still a market need for high-performance engines that can execute CQL queries on the scales of millions of patients. We introduce the \Hermes{} engine as the world's fastest commercial CQL execution engine.
