Counseling Through an Ad Hoc Interpreter
A patient with limited English proficiency presents a new prescription for warfarin 5 mg after a pulmonary embolism. The pharmacy’s trained interpreter service has a 25-minute wait. The patient’s 11-year-old granddaughter offers to interpret. The pharmacist is behind, and the technician has already entered the prescription and printed a English-only leaflet. The patient nods and says ‘okay’ when asked if she understands. The prescription also changed from apixaban, which the patient was taking until yesterday. The pharmacist must decide whether to counsel now through the granddaughter, wait for the interpreter, or dispense with the leaflet and a brief explanation.
1. What are the risks of using the granddaughter as the interpreter?
Read the worked answer
Using the 11-year-old granddaughter as an interpreter is risky. She may misunderstand medical terms, be unable to convey nuanced risks, and be placed in an inappropriate role. Confidentiality and accuracy are compromised, and the patient's nod or 'okay' is not evidence of understanding. The pharmacist should use a qualified interpreter, including telephone or video interpretation, and should not let the technician provide the counseling. A brief explanation plus an English-only leaflet is not adequate for a high-risk anticoagulant.
2. What must the counseling cover for this patient?
Read the worked answer
Counseling should cover why warfarin is being used, the transition from apixaban, the need for INR monitoring, bleeding precautions, consistent vitamin K intake, drug and alcohol interactions, missed doses, pregnancy risk, and when to seek urgent care. Use teach-back with a qualified interpreter and provide translated written materials if available. Confirm the patient knows not to take apixaban and warfarin together unless specifically instructed.
3. How should the encounter be documented and the workflow handled?
Read the worked answer
Document the interpreter used, the counseling provided, the patient's questions, and the teach-back result. If the patient declines counseling, document the refusal and offer it again. Do not document that counseling was complete if it was not. The pharmacist should adjust workflow so high-risk counseling is not delegated to a technician and should not dispense without a plan for language-concordant counseling.
