What type of measure is the timely administration of antibiotic prophylaxis for preventing surgical-site infections?

The timely administration of antibiotic prophylaxis for preventing surgical-site infections is classified as a process measure. Process measures evaluate the methods or actions taken in healthcare that lead to desired outcomes. In this case, administering antibiotics before surgery is a specific action taken to reduce the risk of infections, thus focusing on the steps within the care delivery that contribute to patient safety and quality of care.

By measuring the adherence to this recommended practice, healthcare organizations can assess the effectiveness and consistency of the procedures being followed. Process measures are crucial as they provide insight into how care is delivered, but they do not assess the end results of that care, which is the domain of outcome measures. In this scenario, while the ultimate goal is to reduce surgical-site infections (an outcome), the focus is on the process—how and when antibiotics are administered—making "process" the appropriate classification.
