This paper describes a combined evaluation approach for an information system on intensive care units. Staff self assessment of time needed for documentation activities during admission, daily treatment and discharge/transfer has been compared to a workflow analysis which demonstrated that the system eliminated process steps mainly in daily documentation(More)
INTRODUCTION It is well known that etomidate may cause adrenal insufficiency. However, the clinical relevance of adrenal suppression after a single dose of etomidate remains vague. The aim of this study was to investigate the association between the administration of a single dose of etomidate or an alternative induction regime ahead of major cardiac(More)
OBJECTIVE To identify and summarize the requirements of an optimized CPOE application for pediatric intensive care. METHODS We analyzed the medication process and its documentation in the pediatric and neonatal intensive care units (PICU/NICU) of two university hospitals using workflow analysis techniques, with the aim of implementing computer-supported(More)
The purpose of this study was to introduce clinical decision support (CDS) that exceeds conventional alerting at tertiary care intensive care units. We investigated physicians' functional CDS requirements in periodic interviews, and analyzed technical interfaces of the existing commercial patient data management system (PDMS). Building on these assessments,(More)
BACKGROUND Patient data management systems (PDMS) enable digital documentation on intensive care units (ICU). A commercial PDMS was implemented in a 25-bed ICU replacing paper-based patient charting. The ICU electronic patient record is completely managed inside the PDMS. It compiles data from vital signs monitors, ventilators and further medical devices(More)
Introduction Erlangen University Hospital is a tertiary care university hospital with 1,400 beds. A hospital information system with clinical workstations has been in use for several years (1). Since 2006, a commercial patient data management system (PDMS) has been rolled out successively to include 8 intensive care units of the hospital, covering about 100(More)
BACKGROUND Patient Data Management Systems (PDMS) support clinical documentation at the bedside and have demonstrated effects on completeness of patient charting and the time spent on documentation. These systems are costly and raise the question if such a major investment pays off. We tried to answer the following questions: How do costs and revenues of an(More)
OBJECTIVES Former analyses reported an increased rate of poor direct laryngoscopy view in cardiac surgery patients; however, these findings frequently could be attributed to confounding patient characteristics. In most of the reported cardiac surgery cohorts, the rate of well-known risk factors for poor direct laryngoscopy view such as male sex, obesity, or(More)
OBJECTIVE Mining the electronic medical record (EMR) has the potential to deliver new medical knowledge about causal effects, which are hidden in statistical associations between different patient attributes. It is our goal to detect such causal mechanisms within current research projects which include e.g. the detection of determinants of imminent ICU(More)
Discharge letters are an important means of communication between physicians and nurses from intensive care units and their colleagues from normal wards. The patient data management system (PDMS) used at our local intensive care units provides an export tool to create discharge letters by inserting data items from electronic medical records into predefined(More)
