This document provides an overview and rationale for a "How To" guide on implementing mobile health (mHealth) technologies. It discusses the current healthcare landscape of new care and payment models that mHealth can help address. The guide is intended to help clinicians understand what tools are available and how to evaluate them, and help executives understand what tools are worth investing in. It also discusses how mHealth can help achieve the goals of the National Quality Strategy by improving areas like patient safety, communication, and prevention. Case studies and resources provided by HIMSS on topics like remote patient monitoring are meant to aid in overcoming adoption barriers and selecting appropriate mobile technologies.
