Abstract:  The Hospital Acquired Venous Thromboembolism Prevention (HA-VTE) Model was developed over 36 months via 90 minute virtual meetings by a subgroup of the Knowledge Modeling and Encoding Workgroup. An initial knowledge model (KM) was developed from data in one health organization, modified by data from 6 healthcare organizations, and finalized through an internet-based survey. At each step of the process, consensus was used to determine the data elements included and the relation of these data elements. The attached document shows the model and provides the fully-specified panels, questions, and values that can be used for implementation. The recommendation for HA-VTE Model implementation is to extract data documentation from assessments into a clinical decision support tool.
