The patient flow model, a clinically-focussed, resource-based approach to data modelling

Abstract

The Patient Flow Model is a resource-based approach to the modelling of clinical flows in healthcare settings. Consisting of a conceptual design, a network diagramming convention, and a set of rules used to operationalize the model using mathematical programming techniques, the Patient Flow Model allows decision-makers to explore the complex interactions that exist between how healthcare is provided and the resources needed to provide that care.

The Patient Flow Model is based on the premise that the relationship between a patient and a healthcare facility can be explained using a paradigm that considers patients to exist in a variety of states, each of which is a deciding factor with respect to determining what treatment(s) a patient will receive, and that the treatment received by a patient dictates what resources the hospital will use in order to provide care. The design of the model allows decision-makers to employ a number of approaches to problem solution including optimization, simulation and replication. The model embraces an activity-based approach to cost determination.

Comprehensive functional specifications for the model are developed, a methodology for the creation of clinical and resource networks is described, and demonstration models are illustrated.
