Term: Centralized Data Server Solutions


Definition:

Centralized Data Servers uses a central hub that recieves requests from a computer on the network(client).
"A Centralized Data Server uses a client/server relationship in which a computer (the client) makes a request to use a program from the server, such as accessing e-mail or web access. A client software process may initiate a communication session, while the server waits for requests from any client."

Centralized Data Servers can Simplify and centralize data storage management to support corporate growth, utilize limited data center real estate, and bring IT expenses in line with corporate profitability goals.

Relevance to Health Informatics:

Synchronization of records-

To successfully ingrain EMRs into the healthcare system there must be a coordinated plan to allow patients records to be stored for easy access over the internet. When a patient has multiple doctors and their records are needed in different facilities it is essential to have the most up to date version of the patients health information.

Two storage techniques which can do this are centralized data servers or a peer to peer file system.

“ In the United States, Great Britain, and Germany, the concept of a national centralized server model of healthcare data has been poorly received. Issues of privacy and security in such a model have been of concern.” Experts fear that a centralized model could have many security risks making it an expensive option. However, the main reason this method of storage has not been used is because it is extremly difficult to integrate alreading exsisting databases into one coherent application. Every field that has attempted to unify multiple databases has run into trouble and with Electronic Health Records already having high start up costs many people in the health industry are reluctant to deal with the problem."

Security -
Privacy is at risk with more and more medical information being stored digitally. In order for EMRs to become fully adopted by the health care industry, proper precautions must be taken. The main goal of EMRs are to facilitate more effective measures of information distribution and storage, but this proves to be a risky operation and a huge concern for many of its adopters.

" Although record keeping and sharing of clinical information among caregivers constitutes the main focus of an orthopedic practice’s EMR system, they absolutely need to be aware of issues of ownership and control of data and its security, he said.
To avoid a costly mistake, Cimasi recommended having competent outside counsel review all license, vendor, service and other agreements, whether considering an in-house, out-of-house or hospital-based EMR system. Know where the obligations, liabilities and exposures lie for keeping data private and confidential, particularly when EMRs are incorporated into an overall practice management bundle, he said.
'This process could be one of the most important changes that has ever happened in their practice. It deserves being accorded a significant amount of disciplined consideration.'"

Applications

This could be one way to store Electronic Health Records in the future if the Health industry is able to integrate the many databases in use into one functioning system that hospitals and doctors could access for sharing medical files and research.
