Question

What are the differences between data, information, and knowledge in PHI compared to other health informatics fields? Describe techniques and tools used to generate knowledge from population-wide information.

Answer 1

Ans)Computer data not only lacks meaning, but must includes dates and other qualifiers to gain significance.

- For example,
blood glucose = 127. Was that mg/dl, was the sample drawn fasting, etc.
Everything must be standardized, otherwise computer B will not understand data transmitted from computer A (i.e. data
won't be interoperable).

- Knowledge. Reality talks. Knowing the facts is a stark way of determining the size of the gap between your vision of a healthy community and the reality in which you live. Gathering information from the time period before your organization got started (also known as baseline data) is an excellent way to show the magnitude of the problem.

- A knowledge base is a self-serve online library of information about a product, service, department, or topic. The data in your knowledge base can be from anywhere, but usually comes from several contributors who are well versed on the subject - enough to give you all the details.
