Final answer:
Statement (A) is true, as several studies have disputed the claim that computerized prescriber order entry systems completely reduce errors. They are known to reduce certain errors but also introduce others, and while they may create workflow challenges, they are also associated with numerous benefits.
Step-by-step explanation:
The student's question asks which statement about computerized prescriber order entry systems (CPOEs) is true. The correct statement is (A) Several studies have disputed the claim that they reduce errors. While CPOEs are designed to reduce medication errors and improve safety by using computerized systems to manage prescriptions and medication orders, they are not infallible and the claim that they completely eliminate errors is too strong. It is widely recognized that while CPOEs can reduce certain types of errors, other errors can be introduced or remain unaddressed. Consequently, they do not eliminate the possibility for error by eliminating the reliance on human memory as suggested in statement (B). Statement (C) is also incorrect as CPOEs can provide significant benefits such as improved accuracy in dosing and allergy checks, despite some concerns about potential interference with workflow. Therefore, statement (D), which asserts both (A) and (C) as true, is also incorrect.
