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.

Identifying computerized provider order entry (CPOE) medication errors.
Computerized provider order entry (CPOE) can help reduce the occurrence of medication errors. In Saudi Arabia, CPOE has been implemented for years, with a small number of studies evaluating the impacts of CPOE on medication errors. ⋯ Data was reviewed and evaluated to identify and analyze all drug prescribing errors and subsequently exploring factors that have contributed to the identification of the drug prescribing errors by the dispensing pharmacists. Recommendations on developing policies and procedures, working in a safe environment, healthcare provider awareness, and improved technology to reduce medication errors in Saudi Arabia are discussed.

A guideline-based decision support system for headache diagnosis.
The ratio of correct diagnosis for primary headache has always been relatively low for general practitioners due to the unacquaintance with headache guideline in Chinese primary hospitals. This study proposed a computerized headache guideline method using SAGE module and developed a decision support system for headache diagnosis, which could be expected to help general practitioners of primary hospitals improve diagnostic accuracy. 282 previously diagnosed cases from EMR were used to evaluate the diagnostic accuracy of the system, the result is: migraine 144/153 (94.1%), tension-type headache 89/100 (89.0%), cluster headache 10/11 (90.9%) and chronic daily headache 53/57(93.0%). The proposed system is in the starting phase of the implementation at the outpatient department of Neurology in Chinese PLA general hospital.

A domain-based approach for retrieving trustworthy health videos from YouTube.
Health information retrieval and YouTube can be used as powerful tools to improve user's health knowledge. However, YouTube videos must be carefully analysed in order to avoid misleading, inaccurate, obsolete and incorrect health content. ⋯ Video and channel metadata are used to automatically determine if a video is provided by a trusted source. The approach is tested and results show that the amount of relevant and reliable videos ranked within top-10 increase when using Domain-based ranking, compared with the original YouTube ranking.

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.
