I want to be direct about something that I have seen play out at multiple sites across my career: dispensing errors almost never result from carelessness. They result from shortcuts. The coordinator who "knows" which kit goes to which participant and skips the verification. The coordinator who dispenses from memory during a busy clinic day instead of checking the randomization system. The coordinator who hands a participant their medication and says "same as last time" instead of providing complete instructions. These shortcuts feel efficient in the moment. They are catastrophic when they produce an error.

This lesson teaches the verification steps that prevent dispensing errors, the instructions that participants need to use the product safely, and the methods by which you assess whether participants are actually taking what you dispensed.
