With the Arden Syntax software systems, Medexter offers tools for the representation and processing of medical knowledge based on a standardized syntax. The Arden Syntax is a Health Level Seven (HL7) standard and ANSI-approved.

Heart Failure Readmission Risk Score Calculation
Since November 15, 2013―for over a year―the University of Colorado Health (UCHealth) System in Colorado/U.S.A. has been using Medexter’s Arden Syntax software for the calculation of heart failure readmission risk scores (HFRRSs). The purpose of the HFRRSs is to inform hospital physicians and heart failure nurse practitioners in case of a patient’s increased risk for readmission due to heart failure. In this way, actions can be taken to reduce this risk before the patient’s discharge. Medical knowledge using the Arden Syntax is represented in medical logic modules (MLMs). In Colorado, the entire calculation of the HFRRS is contained within one primary MLM and two subMLMs. These MLMs contain more than 30 data items used for the risk score calculation, including lab data (such as CPK, troponin I, INR), vital signs (such as temperature and pulse), demographics, number of missed clinic visits, and others.

The University of Colorado Health Hospitals
The UCHealth System comprises five hospitals―University of Colorado Hospital in Aurora, Memorial Hospital and Memorial Hospital North in Colorado Springs, Medical Center of the Rockies in Loveland, and Poudre Valley Hospital in Fort Collins―and approximately 400 clinics. They all use Epic as electronic medical record system, into which Medexter’s Arden Syntax software components have been successfully integrated. For this purpose, UCHealth purchased an enterprise-wide Arden Syntax software license for patient care.

Integration in Epic EMR
In the production environment, one Arden Syntax server (distributed on two instances for load balancing) is handling incoming MLM calls. The results are sent back and displayed in the Epic GUI. In the HFRRS case, an email is additionally sent to the nurse practitioners responsible for the patient. The effective implementation of the HFRRS MLMs led to demand for further approximately 50 clinical applications of the Arden Syntax at UCHealth. With the Arden Syntax integrated development and test environments, additional MLMs are currently being developed, for example to classify catheter-associated urinary tract infections (CAUTI) or to measure laboratory-based acute physiology scores (LAPS), comorbidity point scores (COPS), or Charlson comorbidity scores.
