| Popis: | 99 The development of hospital information system in the past was based on the different needs of various departments to deal with different treatment for the hospital administration and healthcare operations needs, such as administrative work, registration, price setting, prescriptions giving and other processes in order to reduce the costs from human resources, staff negligence and generic operations. As supporting healthcare and many related activities, hospitals need to adopt more and more kinds of information systems. Because the implementation timeframes of each system are different, the database formats and the interface would not be the same. Therefore, the data transfer between each system must be coordinated by keying in the data to another system to unify business information or data. So, how to reduce the cost of integration and sharing the data with other systems becomes the important problem that hospitals face. The obvious solution would be transferring the data with each system by deploying the middleware to let the original data be passed to the other systems in the hospital. Previous literature shows that the level of integration is normally divided into four levels. At the highest level, hospital not only can exchange patient data with other hospitals, reducing the waste of medical resources, but also can make integration with the drugs suppliers, increasing medicines inventory turnover, and reducing inventory and procurement personnel costs. To do so, hospitals may improve the quality of healthcare. Thus, the integration of information systems in hospitals is very important. In line of above discussion, the model of this study based on three groups of contextual variables – technological, organizational, and environmental characteristics as primary factors of the integration level of hospital information systems for further test and verification. The data were collected from the hospital in Taiwan and yielding 88 valid samples. The research model was verified by the partial least squares method and regression analysis. The results showed that IT infrastructure, hospital size, external pressure, internal pressure and external support significantly affect the integration level of hospital information systems. Furthermore, this study provides the analysis of what factors affect hospital in the integration of information systems with external organizations. The results of this study can help hospitals understand what factors can increase their level of integration and provide useful suggestions for hospitals managing their systems in the future. |
