Association Between Geriatric Frailty and Medication Related Problems in the Emergency Department to Help Clinical Pharmacists Prioritise Patients

The healthcare systems are under increasing pressure due to a rise in emergency consultations, staff shortages, an ageing population and rising costs. Emergency departments are seeing more vulnerable patients, including elderly people, who are often on multiple medications and at risk of medication errors. To improve safety, the integration of pharmacists specialising in emergency medicine has proven beneficial: their presence in the team improves the detection of medication-related problems, speeds up and optimises treatment, reduces rehospitalisations and lowers healthcare costs. However, in most countries, these pharmacists are still rarely found in emergency departments, mainly due to a lack of resources and clinical prioritisation criteria tailored for them and adapted to this environment. Frailty screening tools and scores, such as ISAR, can be used to identify the elderly patients most at risk, predict adverse events such as fall or mortality, and thus adapt their care in the emergency department. Indeed, elderly frail patients often take many medications and consequently are at risk of medication errors, adverse events, inappropriate prescriptions or serious drug interactions. These patients may therefore require a specialised review on their medication by clinical pharmacists when they are admitted to the emergency department, but their high number make it impossible to care for all of them. We aim thus to evaluate the association between frailty (according to the ISAR score) and medication-related problems among elderly patients admitted to the emergency department. Researchers will examine whether this score can predict the presence of inappropriate prescribing and high-risk drug interactions. If so, pharmacists would then have a quick and easy tool to prioritise patients who would benefit most from a specialised review of their medications when they visit the emergency department.
