Characteristics of frequent users of emergency departments living with major neurocognitive disorders: A cohort study

We included community-dwelling older adults from Quebec who were considered frequent emergency department users (a minimum of 4 visits in the year following an index emergency department visit chosen randomly between January 1, 2012, and December 31, 2013) and who had been diagnosed with at least one chronic condition. We compared characteristics of frequent users living with or without major neurocognitive disorders using chi-square and Kruskal-Wallis tests.

Results. The study cohort consisted of 21,393 frequent emergency department users, of which 3,051 (14.3%) were identified as having a major neurocognitive disorder. The results highlight a higher burden of chronic conditions, polypharmacy, antipsychotic use, and past use of healthcare services among these individuals.

The results also reveal a higher proportion of conditions associated with geriatric syndromes such as trauma and injury, malnutrition, orthostatic hypertension, and gait disorders. Conclusion. Frequent emergency department users living with major neurocognitive disorders represent a complex population.

Our results highlight the importance of systematically addressing their needs in appropriate settings and through customized interventions.
