PTCB Certified Pharmacy Technician (PTCE)Patient Safety and Quality AssuranceHard
A pharmacy is implementing a new policy to reduce the risk of medication errors. The policy mandates that all prescriptions for high-alert medications must undergo an independent double-check by two separate individuals before dispensing. This strategy is an example of which type of error prevention?
- AHuman factors engineering
- BSimplification and standardization
- CAutomation and computerization
- DRedundancy and forcing functions
Show answer & explanationAnswer & explanation
Correct answer: D. Redundancy and forcing functions
An independent double-check is a classic example of redundancy, where an extra step (a second check) is added to catch errors that the first individual might have missed. Forcing functions make it impossible to complete a task without performing a critical step, which is also a form of redundancy and error prevention.
Why the other options are wrong
- A. Human factors engineering focuses on designing systems to minimize human error, like ergonomic workspaces or clear labeling, not specifically double-checks.
- B. Simplification aims to reduce complexity, and standardization creates uniform processes. While valuable, they are not the primary mechanism behind an independent double-check.
- C. Automation involves using technology (e.g., robots, ADCs) to reduce human intervention, which is not what a manual double-check represents.
Redundancy in Error Prevention
Implementing multiple checks or steps in a process so that if one fails, another can catch the error.
- Commonly seen as independent double-checks for high-alert medications.
- Acts as a 'safety net' to prevent errors from reaching the patient.
- Can also involve backup systems or multiple verification points.
