Implementing telehealth applications represents a substantial investment of resources, which is one reason why success is of great interest. Many research and evaluation studies have investigated measures of successful telehealth systems. However, the term "telehealth" represents a wide range of variables including clinical application, characteristics of the information being transmitted, temporal relationships of data transfer and the organizational context. ⋯ Less is known about the relationship among these variables and whether the findings around one variable are generalizable to other settings or applications. For example, organizational support may be essential for successful provider-patient interactions via videoconference, which result in higher quality of life. A conceptual framework would assist in accumulating this type of evidence and supporting more advanced research efforts.

Migration of the Japanese healthcare enterprise from a financial to integrated management: strategy and architecture.
The Hospital Information System (HIS) has been positioned as the hub of the healthcare information management architecture. In Japan, the billing system assigns an "insurance disease names" to performed exams based on the diagnosis type. Departmental systems provide localized, departmental services, such as order receipt and diagnostic reporting, but do not provide patient demographic information. ⋯ It provides the services needed to ensure that data is never lost and is always available, that events that occur in the hospital are always captured, and that resources are managed and tracked effectively. Finally, it reduces costs, raises efficiency, increases the quality of patient care, and ultimately saves lives. Now, we are going to integrate all remaining hospital departments, and ultimately, all hospital functions.

Experimental and theoretical analysis of wavelet-based denoising filter for echocardiographic images.
One of the most significant features of diagnostic echocardiographic images is to reduce speckle noise and make better image quality. In this paper we proposed a simple and effective filter design for image denoising and contrast enhancement based on multiscale wavelet denoising method. Wavelet threshold algorithms replace wavelet coefficients with small magnitude by zero and keep or shrink the other coefficients. ⋯ High spectral content tends to over-estimate the noise standard deviation estimation performed at the finest level of the DWT. As a result, a lower threshold parameter is required to get the optimal S/MSE. The standard WCS theory predicts a threshold that depends on the number of signal samples only.

To optimise the development and implementation process of an electronic patient record, attitudes toward computers in health care and satisfaction with paper records of nurses and physicians of a department in an academic hospital were determined. For this purpose participants received two questionnaires. ⋯ Users who considered themselves as experienced computer users had more positive attitudes. Inexperienced users were more satisfied with the nursing paper record, while no significant differences existed for the paper medical record.
