Metrics

The Purdue Human Research Protection Program (HRPP) and associated Institutional Review Boards (IRB) strive to assist the research community on the application and review processes associated with human subjects research.

The Cayuse IRB protocol review system allows the HRPP to provide the research community with meaningful metrics to establish mutual expectations between researchers and reviewers. We will continue to provide new metrics as they become available.

Review times are reported in three-month intervals expressed as median calendar days. A review begins when a new protocol is certified by the Principal Investigator and ends when a final determination letter is issued by HRPP/IRB. The processing includes all of the following:

  • Verification of personnel and training
  • Pre-review by a protocol analyst
  • Review by an IRB member or designated staff member
  • Response to revisions (both by the HRPP and investigators)
  • Processing the final decision and determination letter
