Studies in health technology and informatics

We live our lives in digital networks. We wake up in the morning, check our e-mail, make a quick phone call, commute to work, buy lunch. Many of these transactions leave digital breadcrumbs--tiny records of our daily experiences. ⋯ It is crucial that behavior-logging technology not be forced on anyone. But legal statutes are lagging behind data collection capabilities, making it particularly important to begin discussing how the technology will and should be used. Therefore, an additional focus of this chapter will be the development of a legal and ethical framework concerning the data used by reality mining techniques.

Needle bending in a VR-puncture training system using a 6DOF haptic device.
The use of virtual reality techniques opens up new perspectives to support and improve the puncture training in medical education. In this work a 3D VR-Simulator for the training of lumbar and ascites punctures has been extended to support the bending of the puncture needle. For this purpose the needle is designed as an angular spring model. ⋯ Proxy based haptic volume rendering is used to calculate the proxy movement. This way it is possible to integrate original CT-patient data into the rendering process and generate forces from structures that have not been segmented. The bending technique has been integrated in a VR-training system for puncture interventions and shows good results concerning update rate and user acceptance.

Interdisciplinary communication in the Intensive Care Unit (ICU) is complicated by the dynamic workflow of clinicians, instability of patients, and highly technological therapies, equipment and information systems. Many countries have examined methods to improve clinician communication and to understand common patient care goals. ⋯ We found that the clinicians studied value the availability of time sensitive information when it impacts their decisions and workflow and trust RNs' judgment of clinical information and situations. Future work should include analyses of RN perceptions of interdisciplinary communication in the ICU.

Our main objective is to detect adverse drug events (ADEs) in former hospital stays. As ADEs are rare, that supposes to screen thousands of electronic health records (EHRs). For that purpose, we need to define a data model that has two main objectives: (1) being able to describe hospital stays from various hospitals (2) being tuned so as to prepare the data mining process: as ADEs are not flagged in the datasets, the data model must be optimized for ADE detection. ⋯ It is compatible with many hospitals. It deals with diagnoses, drug prescriptions, lab results and administrative information. It allows for data mining and ADE detection in EHRs.

The potential of 3-D virtual worlds in professional nursing education.
Three-dimensional (3-D) virtual worlds (VWs), such as Second Life, are actively being explored for their potential use in health care and nursing professional education and even for practice. The relevance of this e-learning innovation on a large scale for teaching students and professionals is yet to be demonstrated and variables influencing adoption, such as increased knowledge, self-directed learning, and peer collaboration, by academics, and health care professionals requires empirical research.
