The idea behind hospital information systems is to make all of a patient's medical reports, lab results, and images electronically available to clinicians, instantaneously, wherever they are. But the higgledy-piggledy evolution of most hospital computer systems makes it hard to integrate all these clinical records. Although several integration standards had(More)
Clinicians usually intend to get overall health status as well as specific health care information from patient's electronic health record (EHR). However, the amount of EHR data can be incredibly large, which makes it a very tedious and inefficient work for clinicians to extract valuable information. This paper first investigates the clinical relevance of(More)
Because of the complexity of the hospital environment, there exist a lot of medical information systems from different vendors with incompatible structures. In order to establish an enterprise hospital information system, the integration among these heterogeneous systems must be considered. Complete integration should cover three aspects: data integration,(More)
Preoperative risk evaluation is a very important work before a cardiac surgery. Clinicians always have to spend much time reviewing the information about operative risk factors. In this paper, we have made a few tentative attempts to help clinicians improve the efficiency of risk evaluation. First a surgery-problem network for cardiac surgeries is built to(More)
Medical examinations and tests are key procedures in clinical practice. Various kinds of medical report systems have been implemented in hospitals today. Most of these systems provide a template-based report editing approach for physicians to customize the content and layout of patient report. But designing such a report template and associating it with(More)
Electric mechanical or chemical signals of biological origin delivered by human bodies can always be of interest for diagnosis, patient monitoring, and biomedical research. Such biomedical signals, namely biosignals, are usually presented by flat file format or proprietary format when digitized for acquisition, storage, transfer and analysis. Recent(More)
