Information

KNOWLEDGE

Biomedical Data: Their Acquisition, Storage & Use

The Data-to-Knowledge Spectrum (data, information, knowledge)

CONSTANTLY EVOLVING CYCLE : KNOWLEDGE CHANGES

EXAMPLE:

Data is the raw facts obtained e.g. My blood pressure is 150/90.

Information is outcome of analyzing data e.g.: My blood pressure is high.

Knowledge is obtained from analyzing information e.g. hypertension is diagnosed when blood pressure is higher that 150/90.

Essential Concepts for Biomedical Computing

Hardware

o Servers // Many Users interacting

o Personal Computers // One User

o Workstations // One user – difference with PCs is: higher performance and better processing for specific tasks

SERVERS

WORKSTATION

PC, Tablets

& Mobile

Essential Concepts for Biomedical Computing

Software

o Programming Languages (MUMPS | Java, C, Perl, PSL…)

o Data Management

o Operating Systems

o Database Management Systems

o Software for Network Communication

BiomedicalComputing:Security

Privacy, Confidentiality, and Security

o Privacy: Control of disclosure of personal health and other information

o Confidentiality: Ability of a person to release or not their personal health information to a doctor, a care provider etc.

E.g. Asking to limit further release or use of the given information

o Security: Protection of Privacy and confidentiality through a series of policies, procedures and safeguards. Control access to the systems and informations

Essential Concepts for Biomedical Computing

Maintaining Security: Parameters

o Availability

o Accountability

o Perimeter

o Role-limited access

o Comprehensibility and control

Maintaining Security: Parameters

o Availability: Ensures accurate and up to date information is available when needed.

o Accountability: Users are responsible for their access and usage of the data. Based on a documented “need to know” and “right to know”

o Perimeter definition: Allows the system to set boundaries of trusted access to an information on the system both physically and logically

Maintaining Security: Parameters

o Role-limited access: Enables access for personnel to only access the information they need and limits access beyond their legitimate need.

o Comprehensibility and control: Ensures that record owners, data stewards and patients can understand and have control over aspects of information confidentiality and access.

New Definition:

Data Stewards Vs Data Custodians

Data Stewards are responsible for what is stored in a data field, while Data Custodians are responsible for the technical environment and database structure.

INFORMATION SYSTEM: Simplified Diagram

ISs can be described as organizational and management solutions to challenges posed by the environment.
