To determine why needlestick injuries occurred and actions to reduce future incidents, what data or information is most useful?

• A. Root cause analysis (RCA) of each injury.
• B. Employee satisfaction surveys.
• C. Random sampling of incidents without RCA.
• D. Maintenance logs for safety devices only.

Answer: (A)

The main idea being tested is using a thorough investigation to uncover the underlying reasons for injuries so you can prevent them in the future. Root cause analysis of each needlestick incident goes beyond the immediate event and looks at all contributing factors—procedural gaps, training weaknesses, equipment design or maintenance, staffing, workload, and environmental conditions. By tracing how and why the injury happened, you identify specific, effective corrective actions that address the true causes, not just the symptom of the event. This approach helps detect patterns across incidents, guiding system-wide changes rather than one‑off fixes.

Employee satisfaction surveys can reveal workload or morale issues, but they don’t provide the causal link between a specific injury and the factors that allowed it to occur. Random sampling of incidents without RCA risks missing critical context and may overlook root causes. Maintenance logs for safety devices alone focus on equipment function but ignore human factors and process flaws that often drive exposures. So, RCA for each incident offers the most direct, actionable path to reducing future injuries.
