Synchronized Immunization NotifiCations

Immunization is one of the most effective public health interventions. Yet, nationally coverage has consistently fallen short of national goals, and has remained for the most part stagnant. The continued presence of vaccine-preventable diseases poses a threat to public health. In addition to needed improvement of immunization coverage for the general pediatric/adolescent population, some children with chronic medical conditions need specific additional immunizations, yet many fail to receive them. Immunization reminders for providers in the electronic health record (EHR) are a type of clinical decision support (CDS) that can reduce missed immunization opportunities. One limitation of these reminders is that they generally depend only on data local to the EHR, which can be incomplete due to record scatter, leading to inaccurate alerts. An Immunization Information System (IIS), also known as an immunization registry, is a population-based system that collects immunization data primarily for children and adolescents from providers at a regional or state level. The investigators seek to couple bidirectional exchange of IIS immunization information and forecasting tools with patient level medical history from the EHR to deliver accurate, patient-specific EHR immunization reminders.
