ASPs - How the
Internet is changing EMR

Healthcare, along with construction,
education and retail are ranked as being the slowest
adopters of IT. With more pressure than ever from government,
insurers and patients, why is healthcare still so far
behind?
As health care becomes more integrated,
electronic medical records (EMRs) have become an integral
part of any practice.
In its simplest form, the concept of EMR is electronic
storage and instant availability of clinical information
to authorized users at the point of care. Increased
efficiency is one of the foremost benefits. Because
of increasing technological advances, we are seeing
the delivery and implementation model of EMR changing
with the times.
Practitioners today have an option to
choose either EMR on “Client-Server” or
an ASP platform.
Traditionally, EMRs had been deployed
directly in the clinic on a Client-Server platform using
a main computer (a “server”) located in
the clinic. The data is then accessed using a “client”
i.e. another computer connected directly to the server
through the local area network (LAN).
However, with the increased demand for
cost-effective EMR solutions, and advances in Web based
technology, many vendors are now offering EMR on ASP
platform.
The Application Service Provider (“ASP”)
model is a way of providing EMR to medical practices
that takes advantage of the Internet. An ASP replaces
the on-site server at a physician’s office with
a server installed and managed at a central data center.
Physicians and practice staff can access the software
applications remotely via PCs connected through the
Internet. It is an effective EMR solution for Solo and
Medium Medical Practices.
The increase in demand and interest in
the ASP model is attributed to the various advantages
it offers over the traditional Client-Server model:
Low cost of ownership:
The foremost advantage to the practice is the reduction
of hardware, software and maintenance costs. Software
installation, maintenance, upgrades, back-up etc. are
carried at the vendors end. The clinic does not require
hiring of specialized IT staff to manage the day to
day activities related to EMR. The user has to pay a
fixed or transaction-based fee, mostly on monthly basis
which also reduces the cost.
Easier accessibility of data at
multiple locations: The ASP based solution
allows the physician to access patient data at multiple
locations via PCs connected to the Internet. This is
very useful for clinics having multiple locations: the
physician does not have to stick to a particular PC
or location to access patient data.
Easier Upgrades & maintenance:
The EMR vendor can centrally update the existing software
at his end rather than going to each site for upgrades.
This results in fast and effortless upgrade without
interfering with the day-to-day operations of the clinic.
Upgrades to a Client-Server platform could also require
upgrading the existing hardware. This adds to the cost
further. With an ASP model, the EMR vendor upgrades
the hardware as needed at his end rather than requiring
the physician to purchase additional hardware.
Greater Flexibility:
ASP platform is far more flexible than Client-Server
systems. Most Client-Server EMRs require the practice
to buy the application outright rather than choosing
a step-by-step implementation. Once the clinic has chosen
a Client Server platform, it is difficult to switch
to a different vendor because the cost incurred during
the initial implementation for hardware and software
is high. As ASP based EMR platforms have enjoyed an
increase in demand, vendors offering these solutions
have to address certain issues in order to increase
the acceptance of ASP based EMRs over Client-Server
solutions:
Security & Privacy of Medical
Records: Since all the medical data is transmitted
over the Internet, patient privacy issues are vital.
In fact, ASP systems can be more secure than most Client-Server
systems. HIPAA Complaint ASP systems are professionally
managed data centers with high level data security systems
in place. Data moves through a secured and encrypted
pathway across the internet with standards such as SSL-128
in use. Firewalls installed at both ends stop unauthorized
access to the network. In addition, Digital Certificates
and PINs are some of the other measures being implemented
by vendors.
Ownership of Medical Data:
Because the patient data is stored at a site outside
of the clinic, prospective ASP clients often ask the
question ‘Who owns the Data?’ In most cases
Service Level Agreements or other legal agreements are
formulated and put in place to ensure that the ASP users
can retrieve their data upon the termination of services,
if they chose to do so.
Availability of Internet Connection: Since ASP platform
is web based, it requires a stable and fast Internet
connection at the clients end. The physician might not
be able to use the solution if the connectivity is slow
or interrupted. Most vendors recommend T-1 or DSL lines,
both readily available in most locations, to ensure
seamless flow of information and uninterrupted workflow.
In summary, ASPs offer an effective alternative
to traditional Client-Server applications with the promise
of lower cost of ownership, greater flexibility, easier
implementation and maintenance. Physicians have come
to realize that ASPs have grown up, and more practices
will begin to migrate to the ASP model in the future
as the concept gains increased acceptance.
