Thumbs up or sad face: Do emojis improve doctor texts? 

A US study finds sending a quick thumbs up isn’t unprofessional, and may even enhance medical messaging.

Sending a heart, a smiley face or a tears of laughter emoji in a text with another doctor may not just be a handy shortcut, but could also enhance communications. 

A study looking at over 1300 texts between doctors at a large US hospital found 7% of the messages included emojis or emoticons, which the authors group together as ideograms.
