TL;DR: A fully verified, executable model is obtained as an end product, enabling a simulation of its associated collaboration scenarios, and provides mechanisms for ensuring that safety properties are enforced and exceptional events are handled systematically.
Abstract: We propose a computer-based framework for the formal verification of collaboration patterns in healthcare teams. In this, the patterns are constructed diagrammatically as compositions of keystones ...

TL;DR: It is believed that a successful implementation of collaborative theorem proving is a necessary prerequisite for the formal verification of large systems.
Abstract: We define the concept of collaborative theorem proving and outline our plan to make it a reality We believe that a successful implementation of collaborative theorem proving is a necessary prerequisite for the formal verification of large systems

TL;DR: This work presents a rigorous methodology for the modelling and implementation of correct by construction healthcare workflows that offers an increased level of trust through mathematical guarantees of correctness for the constructed workflows, including type correctness, systematic resource management, and deadlock and livelock freedom.
Abstract: We present a rigorous methodology for the modelling and implementation of correct by construction healthcare workflows. It relies on the theoretical concept of proofs-as-processes that draws a connection between logical proofs and process workflows. Based on this, our methodology offers an increased level of trust through mathematical guarantees of correctness for the constructed workflows, including type correctness, systematic resource management, and deadlock and livelock freedom. Workflows are modelled as compositions of abstract processes and can be deployed as executable code automatically. We demonstrate the benefits of our approach through a prototype system involving workflows for assignment and delegation of clinical services while tracking responsibility and accountability explicitly.

TL;DR: A generic framework for rigorous workflow modelling and verification that was recently applied to healthcare collaboration patterns is reviewed and it is shown how it can be utilised to help both medical staff and health informaticians build a systematic understanding of informal practices followed during intra-hospital patient transfers.
Abstract: We review a generic framework for rigorous workflow modelling and verification that was recently applied to healthcare collaboration patterns, and we show how it can be utilised to help both medical staff and health informaticians build a systematic understanding of informal practices followed during intra-hospital patient transfers. A case study is discussed, demonstrating how the logical foundations of our approach help capture and enforce significant aspects of intra-hospital transfers that are pertinent to their improvement.

TL;DR: This effort will result in a formally verified, easily maintainable, computer based implementation of HIV ICPs that will greatly improve the current standard of care.
Abstract: We describe ongoing work on the modelling, verification, and implementation of Integrated Care Pathways (ICPs) for HIV patients in Scotland. Healthcare knowledge, including existing policies, guidelines, and best practices, is encoded in formal, process-based, workflow models. This is achieved through the use of our logic-based, modelling framework WorkflowFM, which provides high levels of rigour and trust about the designed ICPs. We believe this effort will result in a formally verified, easily maintainable, computer based implementation of HIV ICPs that will greatly improve the current standard of care.
