IRB Review Times and User Satisfaction

For information on how long it is taking the IRB to review various types of submissions, the table and graph below are updated every quarter. The table displays the number of days (median and range) from date of submission until date of final determination (approval or disapproval) for submissions that reached a final determination during the first quarter of 2024. Since some review processes require that the submission be sent back and forth between the IRB and the investigator, the number of days that submissions spend in the IRB office and the number of days that submissions spend in the investigator’s office are also presented.

Review Times for Submissions that Reached Final Determination During the First Quarter of 2024

New Submissions
Full-board 8 28 (4-84)) 21 (4-50) 3 (0-45)
Expedited 27 8 (1-67) 8 (1-54) 0 (0-15)
Exempt 138 21 (0-99) 21 (0-99) 0 (0-0)


The 75th percentile data, which is how long the IRB takes to finalize the review of 75% of all submissions by type of review are also calculated for each quarter. For the first quarter of 2024 the results are: 55 days for full-board, 23 days for expedited, 98 days for ceded reviews, and 36 days for exempt reviews.

User Satisfaction July 1, 2023, through December 31, 2023

When the IRB makes a determination on a new submission (either approve, or disapprove), we ask the principal investigator (PI) to complete a 6-question online user satisfaction survey. This brief survey allows a PI to comment on various aspects of the review of that specific protocol. In the table below, we have summarized the responses from the surveys that were completed between July 1, 2023 and December 31, 2023 (survey response n=115, 32%). A brief description of each question is shown in the left column. The numbers in parentheses are the responses from the previous time period (January 1, 2023 to June 30, 2023).

These scores are generally comparable to the previous time period. The INSPIR platform (question 6) remains our area of greatest concern. We continue to improve the INSPIR system to try to make it more user-friendly.

Thanks to all of you who cooperated by filling out this survey.
