It is essential that a CREHS solution must be
financially affordable. As with many other com-
mercial products, a CREHS solution comes with
its own investment and operating costs. Investment
costs generally consist of solution and product
technological research, development, and imple-
mentation while operating costs refer to on-going
maintenance cost for systems and equipments. It
is important for solution developers to keep in
mind that the purpose of developing a CREHS
is to provide improved healthcare services and
significantly lower costs for patients located in
rural areas by taking advantage of the price-to-
performance ratio phenomena, and the decreasing
cost of high speed broadband connections.
Economical factors may affect the success-
ful implementation and product acceptance of
a CREHS at specific periods of time. A CREHS
model can be logically divided into three main
components: a wearable wireless sensor device,
the base station at the patients' home, and the
remote central server at the healthcare centre.
However, the operation of such systems highly
relies on the public telecommunication infrastruc-
ture, i.e. the broadband infrastructure available for
specific locations. It is also noted that there is a
relationship between economic and technological
factors. The status of each of these factors will
have significant impact of the other factors. Fast
economy growth may leads to fast development
of specific technology of technology infrastructure
in specific location and vice versa. Depending of
the level of development of the local economy
and technology, in particular, some broadband
technologies may not be available or simply too
high to be affordable to the general public. This
may result in infeasibility of the solution even
though the research, development and procure-
ment costs might be acceptably low. Therefore,
researchers and developers need to have sufficient
information on technology trends and economic
factors leading up to the system release time. It
is important that the proposed solution fit into
the economic and technological landscape at the
time and location.
Environmental concerns are increasingly im-
portant in the development of technology. Because
of potential impacts on the environment, many
countries are becoming more wary of accepting
high-tech solutions. This is due to some potential
impacts on the environment, in many countries
and territories; the hesitation of using high-tech
products does exist. This is a virtual barrier which
might prevent a CREHS from being accepted.
Political and legal requirements can be ob-
stacles which prevent a successfully implemented
product that has been accepted in many different
markets from entering a specific country or tertiary.
There might be various legal and regulatory issues
regarding an e-health system such as requirements
of product component origin, safety regulation,
security and privacy elements for information
processing, transmitting, and storage, insurance,
wireless signal coverage, or the implication of
national health act 1953. These factors, if ne-
glected, can make a CREHS un-implementable.
Stimulating investment in high priority computer
systems and specific tools will deliver tangible
benefits to consumers, care providers, and health
care managers. Encouraging health sector par-
ticipants to adopt and use high priority systems
and tools as they become available. Establishing
an E-Health governance regime helps enable
effective coordination and oversight of national
E-Health activities.
Training, education, sensitization and dissemi-
nation of the system are the final steps in deter-
mining the success of a CREHS implementation.
Implementation of a CREHS will significantly
change the way the patients, healthcare profes-
sionals, and family members interact. This does
requires pre-implementation education and train-
ing, on the job training, and re-training. A CREHS
