An Arabian saying goes "He who has
health has hope; and he who has hope has everything". Unfortunately in a
country like India, advances in healthcare are
still available to the privileged few residing mainly in the urban area but
majority of the population live in rural area. Further, this is compounded by
poor medical facilities in rural and inaccessible areas, reluctance of doctors
to serve in rural areas, etc. Thus, there is little hope for the larger
population of this country for getting quality health care without having A
silent revolution happening in the health sector of the country is Telemedicine,
by Indian Space Research Organisation (ISRO). It hopes to bridge the gap between
haves and have not’s as far as healthcare is concerned.
Telemedicine is the use of telecommunication and information
technology for medical diagnosis and patient care. It involves transfer of
electronic medical data (i.e. live video, high resolution images, voice, text
and patient records) between the “Patient end” and the “Specialist end” using
the combination of video, computer and network communication technologies. The elements of a telemedicine network are
viz., patient end; specialty end and communication link. A telemedicine system
consists of a computer with relevant medical software and connected to medical
diagnostic instruments like ECG, X-ray machine or an X-ray Scanner for scanning
the X-ray images. The digitized images and medical reports of the patient are sent
to the specialist hospital, which may be thousands of kilometers away, through
a satellite VSAT system or terrestrial links. The specialist in the comfort of
his hospital is able to examine the reports, diagnose, interact with the
patient and suggest appropriate treatment during the video conferencing session
through the telemedicine system. Tele-consultation is a great boon in
post-operative care for patients coming from remote areas because money and
time expended on travel is avoided. Telemedicine has its own limitations and it
cannot be used in cases where any disease which requires clinical examination
of the patient cannot be diagnosed by telemedicine eg skin disorders,
pshychiatric disorders, etc. Telemedicine technology as of now in India, has
been adopted in the following areas:-
1.
Tele-consultation.
2.
Tele-diagonsis.
3.
Tele-treatment.
4.
Tele-education
5.
Tele-training
6.
Tele-monitoring
7.
Tele-support.
ISRO has always been endeavouring to reach space technology
to the grassroots. In India, telemedicine started during 2001 linking Apollo
Hospital, Chennai with the Apollo Rural Hospital at Aragonda village in
Chittor, Andhra Pradesh. The next one implemented during March 2002 linked Naryana Hrudayalaya, Bangalore with Chamrajnagar
District Hospital and The Vivekanada Memorial Trust Hospital at Saragur, both
districts being located in Karnataka. Presently, ISRO’s Telemedicine Network
stretches to around 100 hospitals all over the country with 78
remote/rural/district hospitals/health centres connected to 22 speciality
hospitals located in the major cities. The thrust of ISRO’s Telemedicine
Programme are as follows:
- Remote/Rural Hospitals and Speciality Hospitals.
- Continuing Medical Education (CME) – training for
doctors & paramedics in rural/remote areas, from a higher level
hospital/institution.
- Mobile Telemedicine Units
- Disaster Management Support.
The yeoman services rendered by ISRO’s telemedicine network
in remote areas like Kargil and Leh in the North, offshore islands of Andaman
and Nicobar and Lakshdweep, as well as interior parts of Orrisa, Karnataka,
Kerala, Chattisgarh, J&K, North East is noteworthy. As per ISRO’s website,
in Chamrajnagar telemedicine has cut down treatment cost by 81%. Further it is
stated that in case of remote off-shore islands, this is much more significant
both to the patient and the Government administration. In such cases, not only
the patients have the cost saving but can be provided with quick and timely
medical aid. Telemedicine has also been used since 2002 at Pampa, the foothills
of Sabarimala Shrine, Kerala and during Tsunami in Andaman Island and Car
Nicobar.
In India healthcare is a state subject and the larger
application of telemedicine to benefit of the country would depend on the
respective state government’s initiative in grabbing and implementing this
technology. Telemedicine with passage of time will become more and more a
refined technology. Its progress depends on application of mind by the
concerned. High cost of equipments; high cost of maintenance; high training
cost and poor connectivity are some of the impediments in telemedicine gaining
greater acceptance in India. The field of Information and Communication
technology is making giant strides consistently and this over a period of time
should result in reduction in cost of hardware and software which will make
will make telemedicine systems simpler and affordable.
It is seen from ISRO’s website that they have envisioned the
development of a “HEALTHSAT”, an exclusive satellite for meeting the healthcare
and medical education needs of India at large. This satellite, when deployed
along with wireless and terrestrial communication links, can bring a large
change in augmenting the present healthcare delivery system in the country. Telemedicine
when fully implemented can be the mythical Sanjeevini to people living in
remote/rural areas. It can enlarge the gap between life and death across the
length and breadth of this country. We require untiring efforts from all the
stake holders to make India a healthy country.
I would like to state that
I have relied a lot upon material collected from ISRO website and their press
releases.
