Telehealth refers to a collection of wellbeing and healthcare related services and data by means of electronic support and media transmission advances. It permits patient from long-distance and clinician contact, care, guidance, updates, training, mediation, observing, and remote confirmations. Telehealth is the utilization of computerized data and correspondence innovations, for example, PCs and cell phones, to get to social insurance benefits remotely and deal with your human services. These might be advancements you use from home or that your primary care physician uses to improve or bolster medicinal services administrations.
Telehealth is often discussed as a recent concept that appeared in the past few decades. It dates to the 1800s when the telegraph and then the telephone were invented. Telecardiology usage has been documented since the early 1900s when telephones were used to send heart rhythms to distant physicians. Today, every type of health care professional uses the telephone to assess and communicate with patients on a daily basis. Most have also embraced encrypted e-mail or patient portals without realizing that these are all part of telehealth. The recent change that brought telehealth to the forefront of medical care was the rapid expansion of Internet and mobile (e.g., smartphone) technology. Improvements in digital processing and storage capabilities have also reduced the size and cost of the technical infrastructure and support needed to initiate a tele-health program. Older legacy systems were developed for health care entities that could invest in custom information technology (IT) systems, and typically required additional IT support and equipment purchases when a new service was added. More importantly, all but the most complex (and expensive) systems were prone to poor-quality video connections and technical difﬁculties. Current systems are increasingly easy to use, scalable to a variety of clinical needs, and compatible with more devices than just hard-wired desktop computers.
