Clinical, financial, and administrative data include patient demographics records available in institutions master patient index, the Enterprise Master Member Index (EMMI) system; laboratory results dating back over fifteen years; encounter records showing paths of patients across the UAB Health System; clinical images, including CT, MRI, X-rays, and more; and user audit trails, showing the usage of the data by operational and clinical staff. Multiple systems are in place, and an active program to enhance integration and interoperability has been underway for several years.
The Cerner Millennium Electronic Health Record (EHR) is used as the core enterprise clinical system, supporting a complete clinical environment with provider order entry, physician, nursing and other provider documentation, medication management, electronic prescription, bedside device integration, and clinical decision support via alerts and content as some of the primary features. Cerner Millennium objects allows for object-based access to the Cerner system for the purpose of integration. While there is direct database access as well, this is a preferred abstraction layer that protects both Cerner and their customers from breakage due to changes in the database layer.
The Cerner PowerInsight Clinical Data Warehouse is used to support reporting, analytics, quality measures and data extraction for research, clinical and administrative operations within UAB. PowerInsight is built upon the SAP Business Objects platform, a full function Data Warehousing, Analytics, and Business Intelligence, solution. Information from sources other than Cerner is incorporated in order to link with core clinical data. This robust foundation enables the coordination and use of the vast information resources available at UAB in an integrated infrastructure, and forms a key component of the enterprise data warehousing initiative.
Horizon is a UAB-developed web portal used across the UAB Health System. Horizon includes all inpatient discharge and operative notes, all EHR produced clinical notes, all The Kirklin Clinic outpatient documents and notes, and all laboratory and imaging results, each of which is integrated with EMMI to ensure valid patient demographics on the front end of the process. No documents can be created without first selecting a valid EMMI patient, and this occurs via a self-developed CORBA PIDS (Patient Identification Service) implementation wrapped around EMMI.
