Final answer:
It is generally true that when a CPPA is amended, pharmacists must maintain both the original agreement and the addendum for legal and compliance reasons.
Step-by-step explanation:
The accuracy of the statement depends on the specific laws and regulations pertaining to pharmacy practice within the jurisdiction in question. However, generally speaking, in many cases when a Collaborative Practice Agreement (CPPA) is addended, the pharmacist involved is indeed required to maintain not only the original agreement but also the addendum. This is to ensure that there is clear documentation of the terms of practice at all times between the collaborating parties, typically a pharmacist and a prescriber, which is critical for patient safety, legal compliance, and for reference in case of an audit or review.
