Performance Summary Display Ontology (PSDO) is an application ontology about motivating information in performance summaries and the visual and textual entities that are used to communicate about performance. Motivating information includes performance comparisons and changes that motivate improvement or sustainment, such as improvement towards a goal, loss of high performer status, or the presence of a performance gap. Visual and textual entities include charts, tables, and graphs that display performance information. PSDO's domain focus is healthcare organizations that use clinical quality dashboards and feedback interventions for healthcare professionals and teams. Performance information is commonly about the quality of care and health outcomes that have been derived from clinical data using performance measures (aka metrics, process indicators, quality measures, etc). PSDO uses Basic Formal Ontology as its upper level ontology. This work is supported by the NIH, National Library of Medicine (1K01LM012528-01, 1R01LM013894-01).
