Which statement best differentiates continuous quality improvement (CQI) from quality assurance (QA) in medication safety?

• A. CQI emphasizes ongoing system-wide improvements using data; QA verifies compliance with predefined standards.
• B. CQI focuses only on compliance; QA uses data for improvement.
• C. CQI and QA ignore data; they rely on audits alone.
• D. QA is ongoing improvement, CQI is about standards.

Answer: (A)

Continuous quality improvement in medication safety uses data to drive ongoing, system-wide improvements in workflows, technologies, and practices. It follows iterative cycles (plan-do-study-act) to test changes, measure their impact, and spread successful fixes across the system, aiming to reduce risk over time.

Quality assurance, on the other hand, focuses on verifying that processes meet predefined standards and are compliant. It relies on audits, checklists, and verifications to confirm that the expected procedures are followed, rather than continuously changing the system itself.

In practice, CQI would analyze error and near-miss data to identify root causes at the system level, implement changes, and monitor whether those changes reduce errors over time. QA would check that established procedures—like proper labeling, double checks, or dose verification—are consistently performed and that any nonconformances are corrected to restore compliance.

So the best differentiation is that CQI uses data to drive ongoing, system-wide improvements, while QA verifies adherence to predefined standards.
