Work-practice changes associated with an electronic emergency department whiteboard
This study investigates whether the time physicians and nurses at an ED spend in patient rooms versus at the control desk increases after the introduction of an electronic whiteboard. After using this whiteboard for four months nurses, but not physicians, spend more of their time with the patients. With the electronic whiteboard, nurses spend 28% of their time in patient rooms and physicians 20%. Importantly, the changes facilitated by the electronic whiteboard are also dependent on implementation issues, existing work practices and the clinicians’ experience. Another change in the work practices is distributed acces...

Design principles for achieving integrated healthcare information systems
This article focuses on how a small local project termed ‘Standardized pull of patient data’ expanded and is now used on a large scale providing a majority of hospitals, general practitioners and citizens across Denmark with the possibility of accessing healthcare data from different electronic patient record systems and other systems. I build on design theory for information infrastructures, as presented by Hanseth and Lyytinen, to examine the design principles that facilitated this smallscale project to expand and become widespread. As a result of my findings, I outline three lessons learned that emphasize: (...

The use of personal digital assistants in clinical decision making by health care professionals: A systematic review
Ownership of personal digital assistants (PDAs) and smartphones by health professionals is increasingly common. Providing the best available evidence at the point of care is important for time-poor clinical staff and may lead to benefits in the processes and outcomes of clinical care. This review was performed to investigate the usefulness of PDAs in the clinical setting. MEDLINE, Embase, CINAHL and the Cochrane Central Register of Controlled Trials were searched from 2000 to March 2010. Randomised controlled trials that evaluated the effects on the processes or outcomes of clinical care of using PDAs compared with not usi...

On optimal settings of classification tree ensembles for medical decision support
Pattern recognition and machine learning methods provide an attractive approach for building decision support systems. Classification trees are frequently used algorithms for such tasks owing to their intuitive structure and effectiveness. It has been shown that for complex medical data, combining a number of base classifiers improves their overall accuracy. Classification tree ensembles have a certain number of free parameters to set, which can significantly affect their performance. In recent years such ensembles were often used by practitioners without a mathematical background (e.g. physicians), who may be unaware of h...
