Abstract:
Objective:To explore the factors influencing the incidence and duration of delirium in ICU patients, so as to provide a reference for early identification and prevention of delirium in these patients.Methods:A retrospective analysis was conducted on the medical records of 1, 500 patients admitted to the ICU of the Affiliated Jiangning Hospital of Nanjing Medical University from January 2020 to December 2024. The data collected included gender, age, anesthesia method, surgical duration, infection duration, extubation time, duration of mechanical ventilation and hypoxia, Acute Physiology and Chronic Health EvaluationⅡ (APACHEⅡ) score, Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) score, duration of sedative medication, and ICU length of stay. Binary Logistic regression and multiple linear regression analysis were employed to investigate the factors influencing the incidence and duration of delirium in ICU patients.Results:The incidence of delirium among 1 500 ICU patients was 38.4% (576/1 500), with a duration of 1.10 (1.00, 3.20) d. Binary Logistic regression analysis revealed that infection duration, APACHEⅡ score, mechanical ventilation duration, and sedative medication duration were statistically significant factors influencing delirium incidence in ICU patients ( P<0.05). Multiple linear regression analysis revealed that delirium type, duration of hypoxia, use of sedative medications, and length of ICU stay were statistically significant factors influencing the duration of delirium in ICU patients ( P<0.05) . Conclusions:ICU patients have a relatively high incidence of delirium, and numerous factors influence the incidence and duration of delirium. Clinical nursing professionals should identify risk factors early and develop corresponding intervention measures to reduce the incidence of delirium in ICU patients and promote their recovery.
