Model-based immunization information routing.

Abstract

We have developed a model for clinical information routing within an immunization registry. Components in this model include partners, contents and mechanisms. Partners are classified into senders, receivers and intermediates. Contents are classified into core contents and management information. Mechanisms are classified into topological control, temporal control, process control and communication channel control. Immunization reminders, forecasts and recalls in e-mail, fax and regular mail format are routed based on this model. Algorithms for deducing patient provider and patient clinical site relationships are developed to facilitate routing. A dummy provider within each site and a dummy site are created to manipulate routing for incomplete data. 46.63% of patients' primary providers and 92.58% of patients' clinical sites are successfully identified.
