The Pressure Ulcer Model

Overview 

The information below is offered in support of the ONC mobile application challenge grant.   A link to the challenge grant materials is below. This model is based on the Pressure Ulcer Risk Domain Analysis model that passed ballot at HL7 in 2011. This work was developed in collaboration with the Veteran’s Administration, Kaiser Permanente, the SNOMED CT Nursing Working Group and the Clinical LOINC committee. The ballot was reviewed by U.S. national wound and nutrition experts.  The goal of the PU risk model is to represent clinical information pertinent to assessment of pressure ulcer risk and risk management. It is intended to specify information requirements for the domain, not to constrain implementers to any specific logical pattern.

  This model will be integrated into the Federal Health Information Model FHIM at a future date. The Adobe .PDF file represents the original model balloted at HL7: it is included for its helpful introductory material.  The Enterprise Architect and HTML documents below represent the updated model. The spreadsheet contains the terminology values (which are also present in the model). The scope of the challenges addresses the risk assessment package, not the intervention package. The model was developed as an interoperability specification, not a functional application analysis: application behavior is not defined except at the points of interoperability.
