Providers in this arm will receive a secure online notification whenever their patients are visited in the emergency department or admitted as an inpatient.

Providers in this arm will not get a secure online notification about their patient's visit to the emergency department or inpatient admission.

Providers in the intervention group will receive a secure electronic notification when their patients are visited in the emergency department or admitted as an inpatient.

The investigators will measure the time from each patient's discharge until their first follow-up visit in the outpatient setting. The investigators hypothesize that the automated notification will result is earlier post-discharge followups.

Once a primary care provider is notified about their patient's admission via a secure health message (SHM), the investigators will measure number of such SHMs that are read within 24 hours and within 7 days

The investigators will compare the rate of readmission for patients associated with providers in the two arms of the study, to assess if provider's notification about their patient's visit to the emergency department has any effect on rate of readmission.
