The Application and Prospect of

Telemedicine

Abstract—The increasing diffusion of Computer Technology and Telecommunications has made the Telemedicine approach. Telemedicine can provide medical information and services at a distance, which is a fundamental tool to harmonise quality and cost in the Health System. Telemedicine has wide range of applications. In this study, four applications of telemedicine are discussed. They are Teleconsultation, Telemedicine education, Telemonitoring and Health Information Management. At last, the development prospects of telimedicine are also described. Keywords—Telemedicine, Computer Technology, Tteleconsulation, Telecommunications.

I. INTRODUCTION

elemedicine has many definitions and can be viewed as providing medicine from a distance. It should provide patients and practitioners located at remote sites the possibility to access primary or specialty care thereby increasing the quality of care while minimizing costs. Telemedicine takes advantage of the tremendous growth in the telecommunications industry[1].

Today with wireless technology, patient records could be accessed by health-care professionals from any given location by connection to the institution’s information system[2]. Physicians’access to patient history, laboratory results, pharmaceutical data, insurance information, and medical resources would be enhanced by mobile technology, thereby improving the quality of patient care.

Telemedicine is an emerging field that could have a revolutionary impact on health management, bringing the man and his needs in the core of technological progress. The main goal of telemedicine approach, namely to improve access to high quality medical care at affordable cost, can be pursued by means of an effective integration of Hospital and Home Care; also inside Hospital telemedicine technologies play an important rule for medical information exchange among different departments and medical personnel[3].

The popular application and development of the telecommunication networks are telemedicine and teleconsultation. Health experts can solve problems by using the electronic and communication technologies without distance limitation. Telemedicine can provide a cost-saving healthcare mode and can be applied in clinics by using electronic information and communication technologies. The telemedicine is an effective way for distant consultation and for discussion conference [4,5]. Telemedicine can not only improve the accessibility and the quality of healthcare delivery but also lower costs.

II. APPLICA TIONS A．Teleconsultation

Teleconsultation is a means of telecommunication through networks; it is one of the most important applications in telemedicine. Real-time consultations use the video conferencing technology and permit the interaction between medical experts and clients. During consultation, both sites need to communicate with each other and synchronously manipulate images and documents [6].

Patients and their primary care physicians can seek the opinions of experienced specialists thousands of miles away from the comfort of their home. Teleconsultation technology offers a myriad of benefits, ultimately making the provision of quality healthcare more efficient and much more economical.

B．Telemedicine education

Telemedicine education is a rapidly developing application of telemedicine. For example, The students have the possibility to use modern equipment in a Telemedicine Laboratory for image and sound digitisation and to prepare clinical cases in electronic form. Also they can explore Internet resources to search for medical information on the Net. At the end of this course students discuss their prepared medical cases and diagnoses with teachers and medical consultants. So the students can learn more during the class. C．Telemonitoring

Telemonitoring allows the evaluation of patients’ vital signs once or more per day and provide diagnostic information that can be transmitted to health professionals. It has the potential to involve patients more in their own care,assist the titration of medications,improve compliance,and help provides identify early signs of worsening heart failure and its precipitating factors. Home telemonitoring also may assist with care at home or early discharge planning, thereby reducing admissions, hospital days, and rates of mortality[7].

D．Health Information Management

Health information management (HIM) is the practice of acquiring, analyzing and protecting digital and traditional medical information vital to providing quality
