a. Incorrect: One barrier to the use of root cause analysis is time, because this process requires a number of meetings. Other barriers are that persons with relevant knowledge may not be available or may refuse to participate, one person may dominate the discussion, or some may stick to using only timeline method and limit the discussion.
b. Correct: Root cause analysis is used to investigate the causes of near misses, incidents, and sentinel events in health care.

A variety of techniques, such as timelines, cause and effect charts, brainstorming, and re-enactment of an incident can be used in root cause analysis.
c. Incorrect: A number of meetings are required for root cause analysis.
