Asthma App Technical Architecture and EHR Integration. Three information flows (A, B, and C) are shown with dark blue, orange, and tan, respectively. (A) PROs and other data entered into the app by the patient are made available to the provider in a dashboard in the EHR along with auto-generated text that can be pasted into a note. PRO data are stored in the app server but currently not written back to the EHR database. The dashboard is accessible to the provider using Single Sign On and does not require a separate login. (B) If symptoms meet certain criteria, the patient will have the option to request a nurse callback. This request is sent through the app server to the appropriate nurse or nurse pool’s EHR inbox. (C) Upcoming visit information is read from the EHR database on a daily basis. This information is fed through the app server, which sends information to both patients and providers before a visit. Patients receive tips for their visit, reminding them, for instance, to bring their phone and discuss their asthma with their providers. Providers receive EHR inbox messages reminding them to check the dashboard for PROs and other information gathered by the app regarding their patients.
