4. Research involving the collection or study of existing data, documents, records . . . if these sources are publicly available or if the information is recorded by the investigator in such a maner that subjects cannot be identified, directly or through identifiers linked to the subjects. Note: in order to be eligible for this exemption, all data, documents, records, or specimens must exist prior to IRB review and must have been collected for purposes other than the proposed research. (To qualify for an exemption in this category, the proposed research must be strictly retrospective). Later in the boxed summary sections: 5. Please explain how confidentiality will be maintained during and after data collection. If appropriate, address confidentiality of data collected via e-mail, web interfaces, computer servers and other networked information. 7. Individually identifiable information. Will any identifiable information, including images of subjects, be published, shared, or otherwise disseminated? . . . NOTE: if yes, subjects must provide explicit consent or assent for such dissemination . . . Elsewhere, copy of their informed consent requirements: http:// www.irb.uiuc.edu/?q=informed-consent/ElementsOfInformedConsent.html +++ we can, then, quibble a bit over what is or isn't public and you may not be forced to stay within UI's parameters that the data be "historic," But my point is, and has been all along, that working in the field does not exempt one from confidentiality, informed consent, and protection of subjects. One might, for various reasons, get off the hook for SOME of it . . . but when the data used can be traced back to individuals (and MUCH web published data CAN BE). . . I think in most places, using that data without prior informed consent might well be frowned upon by many IRB committees. GAWD I hope this makes it through the list's 10k limit. I'm having a lot of trouble making meaningful points around that limit. [obviously, it did not] Edward Lee Lamoureux, Ph. D.
