"The role of an informaticist is to facilitate the development of systems and processes which enable questions to be answered from available data."Systems and processes need not be "computer programs". They can be card files, paper forms or other methods. Facilitation means that the informaticist is not necessarily the sole person involved in the development of these systems and processes. What informaticists do is bring knowledge about how to use information to the process of designing such systems. The statement doesn't say who is asking or answering the questions. Part of the informaticists role may be in making data available.
If I plug in various adjectives, I can describe various specializations of informatics and informaticists in much the same way:
Medical Bioinformaticists work with (principally) biomedical data, and help biomedical staff answer the questions they have about it.
Clinical informaticists work with (principally) clinical data, and help clinical staff answer the questions they have about it.
Public health informaticists work with (principally) public (or population) health data, and help public health practitioners answer the questions they have above it.
Consumer Health informaticists work with a variety of health data, and help consumers answer the questions they have about it.
This worked well enough for me as an elevator speech that I proceeded with the next step (focusing on consumer informatics), which is the kinds of questions that a consumer has.
The questions that a consumer has with respect to health data are related to three segments of time:
- Understanding the past. How did this happen? What caused it?
- Interpreting the present What can I do about it? What does this mean for me now?
- Predicting the future. What is likely to happen? What can I do to change it?
Let's see where this goes.
