MIROW: Modeling of Immunization Registry Operations Workgroup

NCIRD in partnership with the American Immunization Registry Association (AIRA) is working on an initiative directed at the analysis and improvement of Immunization Information System (IIS) operations. The Modeling of Immunization Registry Operations Workgroup (MIROW) was formed to conduct this work. The goal of this effort is to develop best practice recommendations for IIS operations and processes. It uses a collaborative approach, leveraging Subject Matter Experts (SMEs) from the IIS community to identify and analyze current practices and in a focused, structured process reaches consensus on best practices.   For more information on MIROW, see the below resources:


Recent Events

In April of 2015 MIROW participated in two sessions at the 2015 AIRA National Meeting. The first, MIROW 411, provided a detailed overview of selected MIROW guides. The second, MIROW 101, was a workshop that encouraged participation in gathering feedback for the development of the current topic Decrementing via Electronic Data Exchange. Presentations from both sessions and a Turn Around Document (TAD) summarizing the MIROW 101 session are available here:
