Designing a Drug-drug Interactions Web Service

When two or more drugs are prescribed simultaneously, it may produce drug-drug interactions (DDIs). Current solution to this problem is to download DDIs information from Department of Health and uploaded it to the hospital information system database for on-line usage. This approach will suffer from duplicating investment for large hospitals and lacking such information technology resources for small health units. Since cloud computing advocates software as a service in recent years, we can provide DDIs to all medical institutions by web services. We use the Web Services Business Process Language (WS-BPEL) as our process design tool to reduce the complexity of designing web service. Through web services, the DDIs function can be integrated with heterogeneous computerized order entry system easily, and can solve follow-up maintenance problem. In this way, we can save huge health care resources while guard the drug safety.
