Enhancing the TURF Framework with a Workflow Ontology

The TURF Framework enables usability analysts evaluate EHRs by analyzing work tasks, users, representations, and functionality. Currently the TURF framework does not have a focus on evaluating clinical workflows across multiple tasks or across individuals . Because clinical workflows are vital to the successful implementation of an EHR, this study will augment the capabilities of the TURF usability framework by incorporating a workflow ontology. A novel feature of the workflow ontology is its use of Butler’s Cognitive Work Product (CWP), which complements the TURF framework through its ability to classify workflow actions and resources as contributing to the end goal of the workflow or as overhead. The combination of the TURF framework and the workflow ontology provides a more comprehensive method of evaluating the usability of EHRs.
