Hi Dr R LONJON, This response pertains to: "... In short according to Shannon (theory of information), too much information, no precise, mask the good information to take a decision.
..." REFERENCE (Shannon Information): http://www.iscid.org/encyclopedia/Shannon_Information "... concerned with quantifying information (usually in terms of number of bits) ... as they are communicated sequentially from a source to a receiver ... The amount of ...information contained in a string of characters is inversely related to the probability of the occurrence of the string ... Shannon information is solely concerned with the improbability or complexity of a string of characters rather than its patterning or significance ..." REFERENCE (Complexity): http://www.iscid.org/encyclopedia/Complexity "... often used to describe single systems made of multiple interacting parts. However, ... can be used for a large variety of applications ...* *Computational ... Time ... Space ... Kolmogorov (algorithmic) ... Connectivity ... Descriptive/Interpretative ... Functional ..." Decision Theory (e.g., http://www.answers.com/topic/decision-theory) would be more appropriate. Once Healthcare-related information is available to a Practitioner one enters an environment in which the types of decisions made and the content upon which they are based are outside of Communications Theory (see Decision Theory Reference). Rarely is there 'too much' information. A more important issue is Upon which portion of the available information, or all of it, should a decision be based?
