Auto-selection of DRG codes from discharge summaries by text mining in several hospitals: analysis of difference of discharge summaries.
Recently, electronic medical record (EMR) systems have become popular in Japan, and number of discharge summaries is stored electronically, though they have not been reutilized yet. We performed text mining with Tf-idf method and morphological analysis in the discharge summaries from three Hospitals (Chiba University Hospital, St. Luke's International Hospital and Saga University Hospital). ⋯ Beyond different styles of the discharge summaries, text mining method could obtain proper extracts of proper DPC codes. Improvement was observed by using integrated model data between the hospitals. It seemed that huge database which contains the data of many hospitals can improve the precision of text mining.

Socio-technical challenges in implementing safe patient handovers.
Ineffective handovers in patient care, including those where information loss occurs between care providers, have been identified as a risk to patient safety. Computerization of health information is often offered as a solution to improve the quality of care handovers and decrease adverse events related to patient safety. Drawing on three ethnographic case studies we identify and discuss socio-technical issues which must be addressed if computerized health information systems are to achieve improvements in patient safety related to handovers in care. We suggest that the contextual nature of information, ethical and medico-legal issues arising in relation to information handover and data standards and system integration warrant ongoing research in socio-technical aspects of care handovers.

The use of virtual reality for a human classical conditioning procedure.
The present study investigated the use of a VR stereoscopic figure as conditioned stimulus (CS). A differential conditioning procedure was applied on 67 participants, where a VR stereoscopic figure (CS+) was paired with electric shock and other VR stereoscopic figure (CS-) was presented without shock. ⋯ Besides, the presentation of the CS+ evoked an active expectancy of the unconditioned stimulus (US). The use of VR stereoscopic figures as CSs seems feasible to design innovative experimental paradigms.

In this introduction we summarize the contributions to the Fourth International Conference Information Technology in Health Care: Socio-technical Approaches. We argue that putting to use information systems in health care is a difficult and winding road. ⋯ But this understanding should also lead to better design and implementation methods. Therefore this conference wishes to address the challenges of safe systems and patient safety, ten years after the publication of the landmark reports on human error and quality of health care by the Institute of Medicine.

A myoelectric-controlled virtual hand for the assessment and treatment of phantom limb pain in trans-radial upper extremity amputees: a research protocol.
At least 90% of individuals of limb amputees experience phantom limb pain (PLP). Recent clinical research suggests that providing patients with the mirror image representation of the amputated limb may alleviate PLP. However, mirror therapy cannot be used with bilateral amputees, as visual feedback is dependent on the movement of the intact limb. ⋯ The proposed system allows the patient to directly control the virtual limb by recognizing stump muscle patterns recorded with EMG sensors. The hypothesis behind this strategy is that the VR image of the amputated limb induces better limb imagery than the reflected image of their intact limb and, therefore, is more effective in reducing PLP. A research protocol to test this hypothesis is described.
