ABCDEF Bundle to Prevent Delirium for COPD Patients

Abstract Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disorder characterized by persistent airflow limitation and chronic respiratory symptoms, resulting from abnormalities in the bronchi, bronchioles, and alveoli. Patients with COPD may require admission to intensive care units (ICUs), particularly during acute exacerbations. In this context, both disease management and the prevention of potential complications, such as delirium, are of critical importance. Delirium is a common, preventable, and serious complication in ICUs that prolongs hospital stays, increases healthcare costs, and heightens the risk of infections. Hypoxia-induced cognitive impairment is among the key contributing factors to delirium in patients with COPD.

To improve patient outcomes, the ABCDEF Care Bundle was introduced in 2013 as a structured and evidence-based approach to ICU care. This study aims to evaluate the effectiveness of the ABCDEF Care Bundle in preventing delirium in patients with COPD admitted to the ICU. The research will be conducted as a randomized controlled trial between April and December 2025 in the third-level ICU of Taksim Training and Research Hospital. The study population will consist of COPD patients, with a total sample size of 84 patients (42 in each group), randomly assigned using a computer-assisted simple randomization method. A variety of validated instruments will be used to assess pain, sedation, cognitive status, mobility, and sleep quality.

The findings of this study are expected to contribute to the growing body of evidence supporting structured ICU care and to raise awareness among healthcare professionals regarding the implementation of the ABCDEF Care Bundle.
