Factors of concern regarding drug-related patient safety in emergency department - A summary of results from a randomized controlled trial and observational studies

Drugs are essential to manage symptoms and slow disease progression in many conditions and also to prevent the development of future illnesses. However, drugs also have a risk of causing harm, and transitions of care are a key risk event regarding drug-related patient safety. This dissertation revealed that both incorrect drug lists and drug-related emergency department visits are critical concerns when patients are admitted to Norwegian emergency departments, as this affects 62% and 20% of patients, respectively. Further, it was revealed that integrating clinical pharmacists in the interdisciplinary team of the emergency department improves the quality of the registered drug list and can increase recognition of drug-related emergency department visits. The four studies included in this dissertation have added new knowledge regarding drug information flow, drug-related emergency department admissions, and tailoring of pharmacists-led emergency department interventions. The dissertation challenges the existing procedures for obtaining and assessing drug-related information at admission to the emergency department. Furthermore, the dissertation highlights that increased awareness, tailored interventions, and willingness to take action are necessary to address the presented factors of concern.
