Aim: The present study aimed to clarify the clinical characteristics of patients with dementia in an emergency clinic. Methods: We retrospectively examined patients with dementia who visited the emergency clinic at Kurashiki Heisei Hospital, Okayama, Japan. Among 16 764 patients who visited our emergency clinic in the 3 years from 2014 to 2017, we focused on 2574 (15.4%) patients with dementia. Results: The mean age of patients with dementia was 84.9 ± 0.1 years, which was much older than the age of the total emergency patients (58.1 ± 0.2 years). The hospitalization rate was 54.9% for patients with dementia, which was more than double that of patients without dementia (23.3%; P <0.01), and was higher than that (44.3%) of patients who were aged ≥75 years without dementia. Infection (42.4%) and falls (20.9%) were the most common causes for emergency visits and hospitalization in the present study. Hospitalized patients with dementia spent a longer time in hospital for stroke (64.0 ± 5.3 days) and falls (51.9 ± 2.1 days) than those with infection, epilepsy, syncope, loss of consciousness, other causes (all P <0.01) or dehydration (P ≤ 0.05). Conclusions: Patients with dementia commonly attend our emergency clinic. These patients are older in age, have a higher hospitalization rate and have a longer hospitalization, especially due to stroke and falls, than patients without dementia.
