Institutional review board barriers and solutions encountered in the Collaboration Among Pharmacists and Physicians to Improve Outcomes Now Study: a national multicenter practice-based implementation trial.

Study Objective: To categorize institutional review board (IRB) challenges and solutions encountered in a multicenter practice-based research network (PBRN) study and to assess the impact of IRB requirements on the willingness of individual principal investigators (PIs) to participate in future PBRN studies.

Design: Descriptive analysis of IRB challenges and solutions encountered in the Collaboration Among Pharmacists and Physicians to Improve Outcomes Now (CAPTION) trial, a multicenter prospective cluster-randomized study conducted by the National Interdisciplinary Primary Care PBRN, and a correlational analysis from a survey of individual site PIs.

Measurements And Main Results: IRB barriers encountered and solutions were categorized for study sites. A survey of study-site PIs was conducted with a correlational analysis assessing the impact of various IRB requirements and the willingness of individual PIs to participate in future PBRN studies; of 31 study sites participating in the CAPTION study, 28 study-site PIs were surveyed. IRBs posed a number of challenges including bias regarding the source of the application, issues regarding study design, study instruments, access to patient records, study procedures, Spanish-only speaking subjects, role of clinic physicians, interdepartmental concerns, and updates at continuing review. Responses from the PI survey (21 of 28 PIs surveyed [75% response rate]) indicated that the willingness of an individual to serve as a PI in the future was inversely related to the perceived difficulty of obtaining initial (rS  = -0.599, p=0.004) and continuing (rS  = -0.464, p=0.034) IRB approval.

Conclusion: Significant time and resources were required to address various challenges associated with IRB approval, which had a negative impact on an individual PI's willingness to participate in future PBRN projects. A revision of current rules and regulations regarding the protection of human subjects for practice-based studies, improvement in IRB processes, and support from coordinating centers may decrease the burden associated with IRB approval and increase participation in practice-based research.
