What is a quality indicator (QI) and how is it used in continuous quality improvement?

• A. A subjective rating of staff performance used to assign bonuses.
• B. A set of regulatory requirements for test procedures.
• C. A corrective action plan that must be completed within 24 hours.
• D. A measurable metric reflecting a process or result; used to monitor performance and trigger improvement actions.

Answer: (D)

A quality indicator is a measurable metric that reflects how a process or result is performing and is used to watch performance over time and trigger improvement actions. In continuous quality improvement, these indicators provide objective data about daily operations, showing whether a particular part of the lab is meeting its targets or drifting. By tracking a specific metric—for example, the proportion of specimens rejected due to labeling errors, the average turnaround time for a test, or the precision of an assay measured by CV—a team can spot trends, detect variation, and compare performance against predefined goals. When a quality indicator falls short of the target or shows a concerning trend, the team analyzes the root causes, tests changes through iterative cycles (Plan-Do-Study-Act), implements corrective actions, and then continues to monitor the same indicator to verify that improvement occurred. This creates a data-driven loop that continuously raises the quality of processes and outcomes for patients. Subjective staff ratings used to assign bonuses, regulatory requirements for test procedures, and a corrective action plan with a 24-hour deadline are not quality indicators themselves; they are not ongoing, objective measures of process performance used to drive improvement.
