How often should an analysis of the number of retakes be performed?

• A. Weekly
• B. Monthly
• C. Quarterly
• D. Every three months

Answer: (D)

Tracking retake numbers is a quality assurance activity aimed at spotting trends that point to equipment, technique, or training issues. The best cadence is quarterly. Looking at three months at a time smooths out short-term fluctuations and reveals meaningful patterns across the department, modality, and staff. This timing lets you assess the impact of changes—like new technique charts, updated exposure protocols, or equipment updates—and implement corrective actions in a timely, practical way to reduce unnecessary exposure and wasted rework. Checking too often, like weekly, can produce noisy data and overreact to isolated events. Checking monthly can be helpful in some programs, but it may miss longer-term trends; quarterly analysis provides a balanced, actionable view while remaining manageable. If a sudden spike occurs, you would investigate sooner, but the standard practice remains quarterly.
