A medal for mobile medicine?
Medical services the world over are coming under great pressure to deliver high-quality healthcare and, at the same time control costs. Alongside this, patients are becoming far more involved in their wellbeing as well as wanting a high standard of healthcare with even greater convenience than before. As people are more mobile these days, mobile healthcare (mHealth) avoids the need to visit the doctor’s office and allows patients to provide health data to providers, as well as receive care, anywhere on the planet.
