Imagine attending private lectures and taking all your college exams in your professors’ offices individually, one-on-one. Your instructors lecture you, then pepper you with questions, grading your answers and recording your scores. This is not unlike traditional physician visits. Contrast this to attending classroom lectures and taking online multiple choice exams where a computer algorithm or Scantron tallies your answers and calculates your grade. Classroom instruction with standardized testing is much more efficient that private tutoring. Hundreds of students can learn and take their online exams simultaneously. What if medical productivity could be similarly improved?
Inefficient Physician Communication. When you visit your doctor you are engaging in what’s known as synchronous communication. You queue up in a waiting room and later both you and your doctor meet one-on-one in an exam room (at the same time). You may spend five minutes talking to a nurse and then 10 minutes talking to a doctor. A survey found with waiting and travel time, the whole process takes patients about three hours, on average. Furthermore, many doctors see only about 20 to 25 patients a day. The amount of information conveyed during an office visit is limited — as is the amount of information patients retain. Doctors also must take notes and update medical records during the exam. Fiddling with electronic health records further reduces the amount of useful information exchanged during a 10-minute encounter while your doctor hunts for pull-down menus. The way medicine is practiced is inherently labor intensive, not to mention inconvenient for patients.
Synchronous telemedicine is where you call your doctor or he/she calls back and you talk one-on-one. That may be a little more convenient for patients, but it’s still labor intensive. Asynchronous telemedicine is like email (or snail mail for that matter). You email your doctor or call your doctor and leave a message. Your doctor replies via email or by leaving voicemail. Asynchronous communication doesn’t require both parties to be present at the same time to communicate, but the information flow back and forth can be slow and inhibited compared to talking.
