Assignment 2

"However empirical studies of real-world usage show that even experienced users do not use computer tools efficiently."
Suresh Bhavnani, Bonnie E. John. "From Sufficient to Efficient Usage: An Analysis of Strategic Knowledge." CHI 97.


  1. Verify your group number. Same as last week. The number corresponds to an item in the list of assigned sites below.
  2. The sites were selected by Dr. Pelok, and the questions were generated by him. For clarification of a site or question, please contact Dr. Pelok directly.
  3. The scenario for this assigment is that a patient or patient advocate has come into your office bearing a printout from a web site. The link is given below, and should be the same as that which your group evaluated in Assignment 1, Pt. 2. You are to respond appropriately to this patient's concerns, INCLUDING:
  4. To do this, your group is asked to perform a web search (NOT a MEDLINE search!!!) to locate additional web sites on this topic, and to document the search process on the FRIAR/SECT Internet Search form. (Link should be active Monday afternoon. In the meantime here is a link to the first page of the form.) Criteria which usually most strongly impact on the grade are:

Part 2: SECT


Type of question.
This question is fairly technical, focused on health professional information, and uses some pretty specific terminology.

Select a type of search engine.
Therefore, I am selecting a general search engine rather than a health search engine, since general search engines do a better job with more technical and specific questions, also with professional questions and with rare diseases. Since the terminology is also specific, I am making sure to choose a search engine with a large database. If I retrieve too much, I can always narrow my search the next time around by either adding more terms or choosing a smaller search engine.

Select specific search engine.
I pick Google.

Run a search using first level terms for main topic.
I search with the following terms.


Keeping in mind the criteria from the previous assignment (Patient Information Web Evaluation Checklist), would you actually recommend this site to a patient? Is it a site the patient will be able to access on their own from their home computer or those at a public library or other public computers? If you are not content with your findings so far, return to the searching step and repeat. If you are satisfied, continue by documenting what you recommended to the patient.

NOTE: The article cited above does NOT directly answer the question specified, but could be used as partial justification for a clinical decision, and is given as an example of how to cite an Internet source. To add to a patient's record, I would recommend also including clinician's notes about what clinical decision was made on the basis of this information.


If this was a real patient, at this point you would implement your proposed solution or test out your strategy. If it doesn't work in the real world with a real patient, or if you don't trust your answer enough to try it on a real patient, then perhaps you should reconsider.
