As a recent patient in one of our clinics, I arrived 30 minutes early for a blood draw after being told that was possible, since I had a scheduled a 30 min. meeting with a colleague.  I waited 50 minutes for a late blood draw.  After the blood draw, I then waited another hour  for the appointment.   Keeping the patient informed on approximate time ( like waiting for a delayed airline flight)  The airlines have such an app, why not UCSF?   Scheduled and estimated times would be shown on the patients smartphone app.  I waited from 1PM to 4:30 for what was a 1 hour appointment.  I could have gotten my Starbucks, kept my short appointment if I had this information.  

This app will help clinicians know when blood was taken on their patient and help them schedule their time.  The app would help keep patients happy and would save staff time from being interrupted by people asking when they would be seen.  For administrators, this app would show bottlenecks in the system that need fixing and could increase productivity of the clinic.

This would benefit all, should be fairly simple to create for our clinics.
