Physicians are starting to see SMS as a tool in their field. I previously blogged about using SMS as a smoking cessation tool, and in this related article doctors are using SMS to update families on the condition of their loved ones.
I look at SMS in this sense as a very sophisticated letter. One of the nice things about a letter is that you do not have to respond to it instantly like you do when you are on a hone conversation. I can see doctors preferring this, having a nurse send a message, and not having to answer dozens of questions that they do not know the answer to. It does not surprise me that this is happening in Asia first … a culture that has really embraced the SMS more so than the American users.
