Partial waivers of authorization should be requested from the IRB when you will not obtain authorization from some subjects or for some uses of their PHI. Examples include:

• In one arm of your study, you will obtain authorization from participants with whom you are interacting; however, for another arm of your study, you will use only retrospective medical records from a different group of participants and will not interact with any of the participants in that arm.
• You will access PHI from a HIPAA covered institution outside of UW/UW Health prior to obtaining authorization in order to contact participants to recruit them to your study. This is true even if you are on the medical staff for purposes of providing clinical care of that other HIPAA covered institution. See Accounting for Disclosures in this manual for more information.

Note, however, that healthcare providers may talk to their own patients about enrolling in potentially therapeutic studies without prior authorization or a partial waiver.

Full waivers of authorization should be requested from the IRB when you will not obtain authorization from any subjects. Examples include:

• A study using of only retrospective medical records where you will not interact with any participants.

Researchers are prompted to request partial or full waivers of authorization through the Arrow application.
