Proposal of the patient location tracking and query (PLQ) of IHE integration profile for the better patient tracking.
The Patient Location Tracking Query (PLQ) is the IHE integration profile in order to find the location of patient only in a hospital, not for cross-referencing between multiple hospitals. In Japan, it is common for elderly patients to consult multiple departments in one hospital visit. To find the location of patients quickly is very important for productivity and use of resources in a hospital. ⋯ In order to collect the location of patients, multiple systems must provide the location into central management system. We proposed PLQ for the better patient care in hospitals. We believe that by using this PLQ profile hospital staffs are able to utilize the resource more efficiently.

Overrides of clinical decision support alerts in primary care clinics.
Clinical Decision Support (CDS) systems can alert physicians about potential clinical risks and suggest suitable treatment alternatives at appropriate times in the health care process. We evaluated the frequency with which physicians overrode medication alerts and the override reasons provided. ⋯ Physicians overrode more than half of CDS medication alerts, with formulary, age-based, and renal substitutions the most likely. Many drug-drug and drug-allergy interactions overridden had the potential to cause patient harm.

Analysis of the interface and data transfer from ICU to normal wards in a German University Hospital.
Typically general wards and intensive care units (ICU) have very different labor organizations, structures and IT-systems in Germany. There is a need for coordination, because of the different working arrangements. Our team investigated the interface between ICU and general ward and especially the respective information transfer in the University hospital in Erlangen (Bavaria, Germany). ⋯ In a second step, we investigate the requirements of data transmission in expert interviews. A data transfer concept from the perspective of the nurses and physicians was developed and we formulated recommendations for improvements of process and communication for this interface. Finally the data transfer concept was evaluated by the respondents.

Moving mobile: using an open-sourced framework to enable a web-based health application on touch devices.
Computer devices using touch-enabled technology are becoming more prevalent today. The application of a touch screen high definition surgical monitor could allow not only high definition video from an endoscopic camera to be displayed, but also the display and interaction with relevant patient and health related data. ⋯ This paper describes an approach taken to overcome these problems. A real case study was used to demonstrate the novelty and efficiency of the proposed method.

Video segmentation of moving humans for assistive environments.
In this paper, we present two recently proposed efficient methods for human segmentation from video in indoor environments: the illumination sensitive background method and the self-organizing background subtraction (SOBS) method. Both methods maintain multiple background models. ⋯ The video data are acquired indoors from a fixed fish-eye camera in the living environment. The paper presents the algorithmic implementation and modifications details, while results are also presented for a small number of video sequences.
