A timed model for healthcare workflows based on CSP

Abstract

In order to precisely analyze healthcare workflows, we examine how healthcare workflows can be modeled and verified with an elementary and concise timed CSP extension. To avoid considering healthcare workflows in isolation, we investigate the usage of our CSP dialect for formally modeling workflows alongside the instruction model of the openEHR specification set, which is a general, maintainable, and interoperable approach to electronic health records. Hence, we present a CSP model for openEHR instructions, which allows timed reasoning, and also integrates a basic notion of data and undefinedness. We show that this CSP dialect is suited to verify important properties of healthcare workflows, like workflow consistency, checking against timed specifications, and resource scheduling.
