Which action is least effective in reducing adverse drug events in a care coordination setting?

• A. Relying solely on patient memory for allergies.
• B. Medication reconciliation and reviewing therapy for interactions.
• C. Regular communication about therapy changes.
• D. Collecting a comprehensive medication history.

Answer: (A)

Preventing adverse drug events in care coordination relies on having a complete, documented picture of a patient’s medications and allergies that travels with them across all providers and settings. Relying only on what a patient can remember about allergies is the least effective approach because memory is fallible and patients may not know, forget, or misreport allergies or past adverse reactions. Allergies can be undocumented, misinterpreted, or out of date, and without a shared record across the care team, a clinician may prescribe a medication that risks harming the patient. In contrast, systematic strategies—gathering a comprehensive medication history from multiple sources, reconciling medications to compare current and new regimens, reviewing for drug interactions, and maintaining ongoing communication about therapy changes—create a reliable, up-to-date information flow. This coordinated approach helps identify potential interactions, contraindications, or duplications and ensures all clinicians are aware of what the patient is taking, what has recently changed, and why. That shared, accurate information is what actually reduces adverse drug events across transitions of care.
