Officials at Massachusetts General Hospital in Somerville sent an email to staff asking them to keep from using the app while working in the facility, according to an article on the Healthcare IT News website.
Mass General is not alone in barring its employees from playing the game.
Published reports say that the Utah Valley Hospital in Provo, which is undergoing a large-scale hospital replacement project, is the site of four "Pokéstops," real-world locations where players can obtain virtual items to help them on their quest.
The stops include a statue in the hospital atrium, a statue outside near a fountain, a time capsule in the main entrance, and a spot near the hospital's helipad.
