Pet Medications: A Tail of Caution

Area of Science:

• Pharmacology
• Health Informatics
• Patient Safety

Background:

• Electronic Medical Records (EMR) integrate patient data for comprehensive care.
• Accurate medication history is vital for patient diagnosis and treatment.
• Prescription Monitoring Programs (PMPs) aim to track controlled substance dispensing.

Observation:

• A case report details a 67-year-old female patient with altered mental status.
• The patient's external medication history included phenobarbital and zonisamide, which were later identified as veterinary prescriptions.
• These pet medications were registered under the patient's name and date of birth in the state's PMP.

Findings:

• A lack of standardization between pet medication identifiers in pharmacy databases and state PMP regulations led to the error.
• This resulted in the erroneous inclusion of pet medications in the patient's electronic medical record.
• The patient's pharmacy confirmed the prescriptions belonged to her pet.

Implications:

• Standardization of pet medication identification across databases and PMPs is necessary.
• Pharmacists must meticulously verify patient medication histories, including external sources.
• Enhanced validation processes can prevent medication errors and improve patient safety.
