“This is a wonderful use of technology that gives a doctor the ability to assess and monitor a patient’s condition remotely. But beyond the number crunching and data management, there is still valuable information that can only be gleaned from innate human contact. Contact that is the result of care and close observation provided by a nurse to a patient.”
