Quantum biology on the edge of quantum chaos.

We give a new explanation for why some biological systems can stay quantum coherent for a long time at room temperature, one of the fundamental puzzles of quantum biology. We show that systems with the right level of complexity between chaos and regularity can increase their coherence time by orders of magnitude. Systems near Critical Quantum Chaos or Metal-Insulator Transition (MIT) can have long coherence times and coherent transport at the same time.

Domain-specific analytical language modeling--the chief complaint as a case study.

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 information have not proven to be a panacea.

Analysis of computer-supported oral anticoagulant treatment follow-up workflow.

The objective is to explore the impact of computer-supported reorganization of oral anticoagulation treatment follow-up in a multi-year, multi-clinic pilot study. The focus is on how changes in workflow, namely in anticoagulation workload distribution between nurses and physicians, interact with the quality of care immediately after initial deployment and then later on during the pilot study. The results show that decreases in the physician's time allocation did not result in a lessened quality of care during periods after reorganization.

Toward reflective management of emergency department chief complaint information.

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.

Enhanced normalization of emergency department chief complaints.

There is a need for an efficient and effective means of categorizing Emergency Department Chief Complaints. We improved the performance of our previously described learning normalizer algorithm by broadening its training set to include data from multiple hospitals. We also achieved a statistically significant additional improvement by incorporating a spell-checking algorithm.

Experiences from the Architectural Migration of a Joint Replacement Surgery Information System.

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 evaluation of user experiences. The results from the analysis of clinical end-user and administrator experiences show an increase in the perceived performance and maintainability of the system and a high level of acceptance for the new system version.

Reorganization of oral anticoagulant (warfarin) treatment follow-up.

Objective: To evaluate the impact of the reorganization of oral AC treatment management in a primary healthcare setting in terms of quality of care and cost of care. The evaluated reorganization involved the adoption of an AC nurse service model supported by the use of information and communication technology for storing and handling follow-up data.

Design: Statistical analysis of AC follow-up data, personnel task distribution and resource use analysis, and survey of personnel experiences.

A cost study of new media supported near oral anticoagulant treatment follow-up.

Objective: In this study we sought to develop a comparative cost evaluation between conventional and new media, e.g. web, mobile communication technology and digital television, and near patient testing supported anticoagulant (ac) treatment follow-up in a primary health care setting.

Proposed model of a digital video-based home telecare system.

The purpose of our study was to develop a generic reference model for home telecare in a digital television environment and to suggest how it might be deployed at a test village. We describe here an architecture based on digital video broadcast standards, its components, services, and required additional technical solutions to provide a unified home telecare solution. We also suggest different user groups within the village context and possible service scenarios for them.

Health-related services on the internet.

The primary objective of this study is to evaluate a sample of health-related services available on the internet. In addition, types of new services and service qualities that may be required in the future were estimated. A registered nurse using a questionnaire containing items about usability, quality, and other characteristics related to the subject carried out an evaluation of 100 health-related internet sites, and the results were processed to determine average qualities and graphical presentations for the studied parameters.

Personal health care and the new media in anticoagulant treatment.

Objective: To determine the feasibility of a more personal anticoagulant treatment follow-up routine involving the use of a personal measurement device along with the new media (e.g. the Internet).
