Abstract

RCA3, a novel approach incorporating sustainability audits, may be more effective than the standard RCA2 process in preventing medication error recurrence. RCA3 prioritizes effective, practical, and sustainable actions while distinguishing passive abandonment from active roll back. Thus, RCA3 offers health care systems a valuable tool to enhance patient safety and prevent errors.
