Since November 2013―for over a year―the University of Colorado Health (UCHealth) System in Colorado/U.S.A. has been using Medexter’s ArdenSuite 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. The UCHealth System comprises five hospitals and approximately 400 clinics. They all use Epic as electronic medical record system, into which Medexter’s ArdenSuite software components have been successfully integrated. For this purpose, UCHealth purchased an enterprise-wide ArdenSuite software license for patient care. With the ArdenSuite integrated development and test environments (IDEs) further medical logic modules (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.
