Texting to communicate when a telephone call or email is otherwise not possible provides immediate delivery and may offer an advantage over some other means of communication.  In an article by mHIMSS, the American wireless industry leads the world in overall value, innovation and investment.  As such, it’s safe to say that American consumers use their mobile products and services more than any others in the world.  SpyGlass consulting group found that 94 percent of all physicians in the country are using a smartphone at work.  Texting at work might even make staff members more productive, by sending or receiving a short text message to check on a patient’s status rather than engaging in a lengthy phone conversation. In clinical trails, text messaging technology is sometimes used to measure the success or failure of treatment for subjects in research.
