The development and application of health decision support system (HDSS) in clinical service and health management is efficient in controlling health expenditure rising from overlapped examinations, and in reducing medical errors rising from insufficient decision-making support tools. Typical HDSS in America includes CPOE, MYCIN, QMR, NEDSS etc., which are mainly used in disease diagnosis and treatment, public health emergency management, hospital management, and health insurance management. The successful experiences accumulated in the development of the US health decision support system are worth referring to, such as, integration of management system, decision-makers and ICT, meeting the urgent needs of clinical service and health management, effective E-health construction, and rational development pathway from clinical decision support system to health management decision support system.
In order to understand the latest progress of health decision support system (HDSS) construction, grasp the law of HDSS development and adopt the international advanced experience, this paper took Australia for example, presented a comparative analysis on the construction practices, including the contents, features and system functions of national construction guidelines for HDSS in different periods, and showed the integral development level of Australia HDSS was still in the exploratory stage, and its construction goal, function orientation and construction mechanism got improved gradually with the deep development of public health information. Additionally, to assure the accuracy and safety of HDSS function, Australia has been laying stress on the standard specification construction and system function authentication.
The health decision support system in Canada is embodied in Electronic Health Record Solutions, which includes Public Health Surveillance System, Drug Information Systems, Laboratory Information Systems, etc. By virtue of business intelligence and other advanced information techology, the system can realize the function of statistical analysis, data mining, prediction, and transform information into predicting and guiding knowledge, thus support health decision-making in terms of health surveillance, resources allocation and quality control. The success lie in b support from the federal government, efficient responsible organization Infoway as well as comprehensive and strategic design, which can be served as good enlightenment for HDSS construction of China.
