Bringing IIS immunization data and forecasting tools into a local EHR to power CDS will be helpful for the general population. However, one limitation of immunization CDS, whether provided by an IIS or native to the EHR, is that it does not account for subtleties required by children with certain CMCs who may need extra immunizations specific to their condition or cannot receive certain immunizations. A logical next-step is to couple exchange of IIS immunization data and forecasting tools with patient-level EHR information regarding medical conditions to power accurate, patient-specific EHR immunization reminders. This has yet to be done.
