What must be listed on the printout for electronic data processing of prescriptions?

The correct choice highlights that both new and refilled prescriptions must be listed on the printout for electronic data processing of prescriptions. This requirement ensures that pharmacies maintain comprehensive records for all prescription transactions, which is critical for medication safety, regulatory compliance, and patient care.

Having both categories documented allows pharmacists and regulatory authorities to access the complete history of a patient's prescriptions easily. This comprehensive record is vital for monitoring medication therapy, avoiding potential drug interactions, ensuring adherence to prescribed treatments, and fulfilling legal obligations regarding record keeping. Furthermore, it facilitates audits, inspections, and any inquiries that may arise regarding a patient's medication history.

In comparison, limiting the printout to only new prescriptions or only refilled prescriptions would compromise the integrity and completeness of the pharmacy's records, leading to gaps in information that could negatively impact patient safety and care quality. Similarly, excluding prescriptions older than 30 days misses relevant data that might still be necessary for ongoing patient management and safety evaluations. Hence, including both new and refilled prescriptions ensures a full and accurate representation of the patient's medication history.
