Factors of delirium in elderly patients with mild cognitive impairment in long-term care facilities: a pilot study

Abstract

Purpose: This study was conducted to identify factors that affect the occurrence of delirium in patients with mild cognitive impairment hospitalized in long-term care facilities. Methods: This study analyzed data collected from 2 long-term care facilities. A cross-sectional pilot study was conducted with 42 patients aged 65 years or older and mild cognitive impairment. To identify factors influencing the occurrence of delirium, multiple logistic regression analysis including general characteristics, risk-related, and medical characteristics was performed. Results: Delirium occurred in 14 (33.3%) of the participants. Hypoactivity was seen in 6 participants (42.86%), hyperactivity in 7 (50.0%), and a combination of both aspects in 1 (7.14%). The results of multiple logistic regression analysis showed that delirium in patients with mild cognitive impairment in long-term care facilities had a high occurrence in patients wearing diapers. Conclusion: This study identified the occurrence of delirium in patients with mild cognitive impairment hospitalized in long-term care facilities. One of the factors affecting the occurrence of delirium was “wearing diapers.” The findings can be used to train nurses on delirium evaluation and intervention and to help prevent and manage delirium in long-term care facilities. This study suggests that further research is necessary to reduce the incidence of delirium.
