Which of the following is an environmental benefit of using electronic data interchange (EDI) for controlled substance orders?

• A. Paperless eco-friendly environment
• B. Faster processing time
• C. Enhanced transaction security
• D. Reduced human error

Answer: (D)

The environmental benefit comes from eliminating paper in the ordering process. When orders are transmitted electronically, there's no need to print forms, generate paper copies, mail documents, or store physical records. This directly reduces paper consumption, ink and energy used for printing, and waste from discarded papers, plus the energy and emissions tied to transporting and shelving physical documents. While faster processing, stronger security, and fewer manual mistakes are important operational advantages, they don’t represent an environmental improvement as directly as going paperless does. So the clear environmental win is the paperless, eco-friendly nature of electronic orders.
