The ease of use! I love that it is so simple for my staff at work when we are in different locations around our hospital system (we have 4 hospitals).
This has been very helpful with patient care while working from home or being out-of town during an emergency situation where there was no other way than using this app as well since all doctors were not available via phone call/email etc..I feel like i can trust them more now due their easy accessability through apps such as shepherd which they previously had difficulty accessing because some providers would only allow emailing instead if calling over cell phones but once you get used too its great!!
