INTRODUCTION e-HEALTH is defined as: Application of the Internet and other related technologies in the healthcare industry to improve the o Access o Efficiency o Effectiveness o Quality of treatment o Business processes utilized by healthcare organizations, practitioners, patients and consumers with the help of next generation networks (NGN) to Improve the health status of patients.
WHO defines e-Health as...e-Health is the cost effective and secure use ofinformation and communication technologies insupport of the health and health related fieldsincluding healthcare, health surveillance and healtheducation, knowledge and research.
NGN NGN : Next Generation Networks With recent trends and technology advancement in the development of converged broadband next generation networks (NGNs) and advanced multimedia services, the potential has increased in delivering of various e-Health services to end users “anywhere, anytime”.
QoS QoS : Quality of Service The wide variety of e-Health services impose different Quality of Service (QoS) requirements on underlying networks.
QoS Requirements for e-Health Services e-Health Service Classification Multimedia Conferencing a) Still and Streaming Medical Images b) Transmission of Patient Vital Signs c) Tele-Robotic System d) Research and Education
Mapping of e-Health servicesMapping in e-Health isa particular servicemay comprise multiplemedia types and trafficflows that may need tobe mapped todifferent areas wherethe service is required.
Tele-Consultation Tele-Consult or e-consult or Tele-Medicine It involves real-time video conferencing and streaming of ECG signals between a patient and a doctor. The service enables a patient or doctor to initiate an e-consult session using an appropriate research prototype client service media application.
e-Health Related services• Index of available programs and services.• Calendar of events.• Patient satisfaction surveys.• Service provider directories.• Patient e-mail services.• Health news.
m-Health• m-Health includes the use of mobile devices in collecting aggregate and patient level health data.• Providing healthcare information to practitioners, researchers, and the patients.• It ensures a great support to the e-Health programs.
Disease management scopes Health risks assessment Patient support groups Online discussion forums Moderated chat with guest experts comprehensive patient education “Ask an expert” triage for patients seeking medical advice Electronic newsletter subscription
Benefits of e-Health Improve communication among healthcare stakeholders. Facilitate better decision support. Reduce medical errors. Enhance reporting capabilities. Encourage disease prevention and wellness.
e-Health challenges 6 main areas of e-Health challenges are...o Information (Inaccurate and Incomplete)o Human resources (Inadequate or Brain- drained)o Infrastructureo Quality and security of data.o Financial and legal issues.o Authenticity
Conclusion and Future Scope Developed research and training in this field. Working of Govt. And Private sectors in a parallel manner. Prioritisation of the information flow with ICT. Public support. Advancement of technologies. Lead a long, healthy and a prosperous life.
