ABSTRACT
Process-aware EHR BPM systems: Two prototypes and a conceptual framework
Studies in health technology and informatics

Business process management (BPM) systematically optimizes process effectiveness, efficiency, and flexibility. Therefore BPM offers relevant ideas and technologies. We provide a conceptual model based on EHR productivity and negative feedback control that links EHR and BPM domains, describe two EHR BPM prototype modules, and close with the argument that typical EHRs must become more process-aware if they are to take full advantage of BPM ideas and technology. A prediction: Future extensible clinical groupware will coordinate delivery of EHR functionality to teams of users by combining modular components with executable process models whose usability (effectiveness, efficiency, and user satisfaction) will be systematically improved using business process management techniques.

It consists of an information browser, three clinical applications, and three management applications. FELIX was developed in a community hospital environment, but has conceptual and technical roots in medical informatics and the Internet.

I outline a project to Web-enable an existing computer-based patient record (CPR) in the context of ideas from philosophy, linguistics, artificial intelligence, and cognitive psychology. Web prototypes play an important role (a) because Web technology lends itself to rapid prototype development, and (b) because prototypes help team members bridge among disparate medical, computing, and business ontologies. Six Web-enabled CPR prototypes were created and ranked. User scenarios were generated using a user communication matrix. Resulting prototypes were compared according to the degree to which they satisfied medical, computing, and business constraints. In a different organization, or at different time, candidate prototypes and their ranking might have been different. However, prototype generation and comparison are fundamentally influenced by factors usefully understood in a cognitive science framework.

Workflow Management and EHR Usability EHR workflow management systems are more usable than EHRs without workflow management capability. Consider these usability principles: naturalness, consistency, relevance, supportiveness, and flexibility. ...

A formal theory of cognitive deficit has four parts. (1) For a normal representation we use the concept of sound and complete "self-...

We propose an information processing model accounting for behavioral similarities in depression and ...

DEP (Depression Emulation Program) Implements key aspects of a computa-tional theory of "normal" adaptive reactive depression. A the-ory of "normal" depression is a ...
