Progressive Dyspnea in Patient Safety, Preventive & Ethics — 56yo Man | Patient Safety | SMLE Q#5888

A 56-year-old man recently immigrated from a malaria-endemic area is admitted with progressive dyspnea and bilateral leg swelling. He is started on digoxin for symptomatic heart failure. Within 24 hours, he develops nausea, yellow-tinged vision, and marked bradycardia. A detailed medication history obtained later reveals he has been taking a chronic medication obtained abroad that can interact with prescribed drugs. The hospital safety committee classifies this as a preventable adverse drug event related to prescribing and medication reconciliation. What system-level intervention would most effectively prevent this type of complication in the future?
