The Wall Street Journal recently featured an article on mobile applications used in health care. Mobile apps for smartphones and tablets are changing the way doctors and patients approach health care. While most apps are designed for doctors, some are designed for use by patients. Patients can use mobile apps to gather diagnostic data or coordinate care to track conditions and treatments. Apps that enable doctors to capture an image and upload to a patient’s medical record, such as CliniCam, are helpful in describing a patient’s condition. Some apps may prove be useful time savers. However, the field of mobile app development in health care still has ample room to grow, giving rise to questions regarding patient privacy during this era of budding technology.
