A common, preventable, and treatable disease characterised by persistent respiratory symptoms and airflow limitation due to airway and/or alveolar abnormalities, typically resulting from extensive exposure to noxious particles or gases, and influenced by host factors including abnormal lung development is Chronic Obstructive Pulmonary Disease (COPD). Patients hospitalised to the intensive care unit (ICU) with AECOPD were analysed, and the DECAF score and the previously established BAP65 score were compared to see which is better at predicting mortality and the requirement for IMV. Methods: Fifty patients were enrolled in the trial, all of whom had been transferred from our emergency room to the intensive care unit due to an exacerbation of their COPD. FindingsBUN >25 (21.43 percent in discharged group vs. 62.50 percent in died group, P = 0.018), Altered mental status (11.90 percent in discharged group vs. 50.00 percent in died group, P = 0.026), and pulse >109 bpm (21.43 percent in discharged group vs. 75.00 percent in died group, P = 0.002) were significantly different between survivors and died patients. For patients above the age of 65, there was no statistically significant difference between the released and deceased groups (40.48 percent vs. 75.00 percent, P = 0.073). Conclusions: COPD is a severe health disease that affects patient health and life, and represents a burden for the health systems. The mean value of the BAP 65 score was 2.191.04 in the discharged group, and 3.751.58 in the dying group, with a very significant difference between groups (P= 0.001). Death from COPD exacerbation is preventable, making early identification and care of the disease crucial. The prognosis of a patient undergoing AECOPD may be evaluated using not only clinical judgement, but also the BAP65/DECAF scoring systems, which take into account a number of parameters.
