The VA is apparently working on an iPad app that would help ER nurses triage patients and determine how soon the patient needs to be seen by a doctor. The system is a pretty standard "decision support system" (DSS) that takes into account the patients' symptoms, vital signs, medications and other information in the medical records to make triage recommendations.
The question I have, however, is why tablet computers? Such DSS has been around for 40 years -- mostly integrated with existing EHRs. Why build a brand new app on the tablet instead of leveraging the EMR interface that already exists? What value-add does "mobile" bring in the ER triage process? Doesn't the nurse have ready access to computers? I can see the value of a mobile DSS for a field EMT, which I believe is already being developed by the DoD.
