Developing Data Exchange Protocol Standards for Healthcare Simulators

We describe efforts undertaken to create a standard set of data exchange protocols that facilitate interoperability between simulators used in the healthcare field.   The need for standard data arises for several reasons including exchange of information between the same simulators placed at different locations or the exchange of information between different simulator architectures.  Training and education of geographically separated teams with different skill sets can require different simulators with differing levels of fidelity. A set of prototype exchange data is presented representing patient information and physiology.  There are currently two records; one supporting lower fidelity simulators and the other supporting higher fidelity simulators.  The individual parameters were selected and grouped by investigating inputs and outputs from several simulator companies.  The range of variables is derived from the medical literature.  The data structures embellish the Army’s Synthetic Environment Core Life Form data structures and are intended to be balloted to become part of the IEEE 1278 set of standards used to define interactions between many simulators. The data structure presented also uses some of the parameterized aspects of the Medbiquitous virtual patient standard. Additional efforts described include expansion of the data structure to include information that is conveyed external to the simulators but is needed to support interoperability.
