Before dispensing an outpatient prescription for a controlled substance, which condition requires the pharmacist to review the patient's OARRS report?

The requirement for a pharmacist to review the OARRS (Ohio Automated Rx Reporting System) report before dispensing a controlled substance is particularly pertinent when a patient adds a different or new controlled substance to their therapy. This is crucial because the addition of a new controlled substance can significantly affect a patient's risk of substance misuse or overdose. By reviewing the OARRS report, the pharmacist can assess the patient's overall prescription history for controlled substances, looking for potential red flags such as overlapping prescriptions from multiple prescribers or excessive quantities that might indicate misuse or abuse.

In this context, the other conditions also highlight important situations where a review of the OARRS report would be beneficial, but the need to check when a new medication is added stands out as particularly critical for ensuring patient safety and adherence to legal requirements. The OARRS report serves as a valuable tool for pharmacists to ensure comprehensive medication management and to protect against the risks associated with polypharmacy in controlled substances.
