Intermountain Healthcare (Intermountain) has developed and deployed a document collection of over 700 evidence-based inpatient interdisciplinary patient care standards as a means of improving patient care by reducing practice variability. We propose to identify and structure action concepts from these care standards, define their embedded work items and relative financial values, and use the coded concepts as the application development construct that enables patient workload requirement and cost prediction. Valid action concepts will conform to a compositional terminology model that details clinically meaningful information at various levels of granularity as well as the minimum required experience (e.g., licensure) and relative probable effort required for performing the action. The projected total actions that a patient requires will form the basis for workload and cost prediction.
