What is a forcing function in medication safety, and what is a typical example?

• A. A design that speeds up medication delivery by skipping checks.
• B. A policy requiring double checks after administration.
• C. A design that prevents unsafe actions, such as barcode scanning prevents administration if a patient/drug mismatch.
• D. A training module for staff about safety.

Answer: (C)

A forcing function in medication safety is a design feature that prevents an unsafe action from being completed, meaning you cannot proceed until the safety condition is met. In practice, a common example is barcode scanning that verifies the patient identity and the drug; if the patient and medication don’t match, the system blocks administration until the mismatch is resolved. This approach changes the process itself to stop errors before they reach the patient, rather than simply relying on reminders, policies, or training. The other options describe procedures or training or incentives that still rely on human action and vigilance, rather than physically preventing the unsafe step.
