MDD(Mild Cognitive Impairment Delirium Dementia) Cohort

Keimyung University Dongsan Medical Center163 enrolled

Overview

* Identify the degree of delirium in subjects with mild cognitive impairment and find the risk factors of delirium. Mortality, hospital stay, and medical expenses are analyzed as clinical consequences related to delirium incidence. * Dementia conversion rate and conversion period of subjects with mild cognitive impairment with delirium and it identifies the effect of delirium on dementia conversion. * Develop an AI(Artificial intelligence) algorithm for predicting dementia transition in subjects with mild cognitive impairment based on the research results of the 1st, 2nd, and 3rd years.

Outcomes

Primary Outcomes

Delirium incidence in participants with mild cognitive impairment

descriptive statistics

Time frame: The number of subjects evaluated as positive in the delirium assessment using S-CAM for 30 days from the 1st day of study participation is statistically calculated.

Dementia conversion rate and transition period in participants with mild cognitive impairment

descriptive statistics

Time frame: The participant's dementia conversion is checked in units of 1 month, and the period until conversion to dementia is analyzed in units of 12 months for 36 months.

Secondary Outcomes

Risk factors affecting participants' delirium

Logistic Regression

Time frame: On the first day of data collection, the characteristics of subjects are collected through medical records. After 12 months, the risk factors affecting the occurrence of delirium among the characteristics of the subject are analyzed.

Mortality

Kaplan-Meier survival, Cox proportional hazard regression, Logistic Regression

Time frame: It is statistically calculated in 30-day, 60-day, 12-month, 24-month, and 36-month increments.

hospital length of stay

Linear Regression

Time frame: The period from hospitalization to discharge is calculated in days and analyzed in units of 12 months.
