As a medical student 15 years ago, my “peripheral brain” consisted of fat textbooks sitting on office bookshelves or smaller, spiral-bound references stuffed into the bulging pockets of my lab coat. As a doctor-in-training, I replaced those bulky references with programs loaded onto PDAs. Today, smartphone apps allow health professionals at all levels to access the most up-to-date medical resources such as drug references, disease-risk calculators, and clinical guidelines—anytime, anywhere.
Apps have several advantages over traditional medical texts. First, the information is always current, whereas many textbooks are already dated by the time they hit shelves. If I have a question, I can look up the answer on my smartphone without leaving my patient’s side. And unlike textbook chapters, many medical apps have interactive features that help doctors choose appropriate screening tests for patients, recognize when immunizations are due, or calculate a patient’s risk of developing heart problems.
Lastly, apps can enable remote monitoring of high-risk patients and reduce the need for office visits. In a small study published in PLoS ONE, for example, researchers found that patients hospitalized for heart vessel blockages were able to complete “supervised” rehabilitation exercise sessions in their homes with a portable heart monitor and GPS receiver that transmitted real-time data to doctors via smartphone.
