An approach coined as "reflective information management" is presented as a technique for the management of emergency department chief complaint information. The architecture of a system integrating principles from this approach is described and its performance is evaluated in providing categorical information from free-text chief complaints for use, e.g.,(More)

PURPOSE A large share of the information in electronic medical records (EMRs) consists of free-text compositions. From a computational point-of-view, the continuing prevalence of free-text entry is a major hindrance when the goal is to increase automation in EMRs. However, the efforts in developing standards for the structured representation of medical(More)
The goal of this study is to present the experiences gathered from the migration of an existing and deployed joint replacement surgery information system from a classical 2-tier architecture to a 4-tier architecture. These include discussion on the motivation for the migration and on the technical benefits of the chosen technical migration path and an(More)
| Multi-delay predictive FIR lters utilizing a small number of multipliers are proposed. These lters are shown to have substantially lower noise gain than the standard minimum-length predictors using the same amount of multipliers. These lters are formulated for both arbitrary-order polynomial and sinusoidal signal prediction. The use of dynamic programming(More)
