Objectives:
Duplicative institutional review board/research ethics committee review for multicenter studies may impose administrative burdens and inefficiencies affecting study implementation and quality. Understanding variability in site-specific institutional review board/research ethics committee assessment and barriers to using a single review committee (an increasingly proposed solution) can inform a more efficient process. We provide needed data about the regulatory oversight process for the Sepsis PRevalence, OUtcomes, and Therapies multicenter point prevalence study.
Design:
Survey.
Setting:
Sites invited to participate in Sepsis PRevalence, OUtcomes, and Therapies.
Subjects:
Investigators at sites that expressed interest and/or participated in Sepsis PRevalence, OUtcomes, and Therapies.
Interventions:
None.
Measurements And Main Results:
Using an electronic survey, we collected data about 1) logistics of protocol submission, 2) institutional review board/research ethics committee requested modifications, and 3) use of a single institutional review board (for U.S. sites). We collected surveys from 104 of 167 sites (62%). Of the 97 sites that submitted the protocol for institutional review board/research ethics committee review, 34% conducted full board review, 54% expedited review, and 4% considered the study exempt. Time to institutional review board/research ethics committee approval required a median of 34 (range 3-186) days, which took longer at sites that required protocol modifications (median [interquartile range] 50 d [35-131 d] vs 32 d [14-54 d)]; p = 0.02). Enrollment was delayed at eight sites due to prolonged (> 50 d) time to approval. Of 49 U.S. sites, 43% considered using a single institutional review board, but only 18% utilized this option. Time to final approval for U.S. sites using the single institutional review board was 62 days (interquartile range, 34-70 d) compared with 34 days (interquartile range, 15-54 d) for nonsingle institutional review board sites (p = 0.16).
Conclusions:
Variability in regulatory oversight was evident for this minimal-risk observational research study, most notably in the category of type of review conducted. Duplicative review prolonged time to protocol approval at some sites. Use of a single institutional review board for U.S. sites was rare and did not improve efficiency of protocol approval. Suggestions for minimizing these challenges are provided.

Random Variables
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
