Telemedicine

The use of advanced telecommunicationand information technologies to exchangehealth information and provide health

care services across geographic, time,social and cultural barriers

It includes both, the clinical (diagnosis,treatment and medical records) and

academic medicine (research, educationand training).

The Goals of Telemedicine Systems

Increase the accessibility of and to professionalcaregivers

Increase the quality and continuity of care topatients

Increase the focus on preventive medicinethrough early intervention

Reduce the overall cost of healthcare

For education and training

For providing services to remote areas in case ofnatural calamities, disasters and military andspace operations.

Findings of its use in emergency

services

The system did not intrude into theprivacy of the patients or theparamedics

It was easy to use

It was adequate for conductingclinical examination

It conveyed critical clinicalinformation


16/18

Barriers

Technological

Infrastructure planning anddevelopment

Telecommunication regulations

Reimbursement

Licensing and credentialing

Medical malpractice liability Confidentiality

Conclusion

Makes specialty care more accessible torural and medically underserved areas

Improves communication betweenproviders

Educational to remote and consultingpractitioners

High patient and provider satisfaction Keeps local healthcare dollars in local

community Possibly improves process of care and

quality of care


18/18

Conclusion

Reduced overall cost of healthcare

Telemedicine distance learning programmes canaddress healthcare professional shortage

However the study, development and use of

telemedicine is still emerging with the advent ofnew technologies (medical and information)

There are several barriers that needs to beremoved to make telemedicine a model forPervasive Healthcare and fulfill WHOs goal of

Health For All by the year 2010.
