Interactive Query Workstation: standardizing access to computer-based medical resources.
Methods of using multiple computer-based medical resources efficiently have previously required either the user to manage the choice of resource and terms, or specialized programming. Standardized descriptions of what resources can do and how they may be accessed would allow the creation of an interface for multiple resources. This interface would assist a user in formulating queries, accessing the resources and managing the results. This paper describes a working prototype, the Interactive Query Workstation (IQW). The IQW allows users to query multiple resources: a medical knowledge base (DXplain), a clinical database (COSTAR/MQL), a bibliographic database (MEDLINE), a cancer database (PDQ), and a drug interaction database (PDR). Descriptions of each resource were developed to allow IQW to access these resources. The descriptions are composed of information on how data are sent and received from a resource, information on types of query to which a resource can respond, and information on what types of information are needed to execute a query. These components form the basis of a standard description of resources.
