In a QA program for hand hygiene, which metric best reflects adherence?

• A. Rate of hand hygiene adherence among healthcare team
• B. Number of gloves purchased
• C. Patient satisfaction scores
• D. Medication error rate

Answer: (A)

The main concept being tested is how we measure whether healthcare staff actually follow hand hygiene protocols. The best metric is the rate at which the healthcare team performs hand hygiene according to the established guidelines. This directly captures adherence to the hand hygiene process and shows how consistently the team is complying with the needed precautions to prevent infections.

Other options don’t directly reflect whether hand hygiene is being performed. The number of gloves purchased is a supply metric and doesn’t tell us if hand hygiene is actually happening. Patient satisfaction scores are influenced by many factors and don’t isolate hand hygiene behavior. Medication error rate relates to medication safety processes and not to hand hygiene practices.

In QA programs, a rate-based adherence metric provides a clear, actionable measure of whether the process is being followed, which informs targeted training and reminders to improve compliance.
