The Impact of Lactate Clearance, Bilirubin, and Albumin on Mortality in Elderly COPD Patients: Insights from Emergency Department Data

Aim: Chronic obstructive pulmonary disease (COPD) is a common respiratory condition characterized by symptoms such as cough, dyspnea, and airflow limitation. The prevalence and health risks of COPD increase with age, making emergency interventions crucial for elderly patients. This study investigated the influence of bilirubin, lactate clearance, and albumin levels on mortality rates among elderly COPD patients in emergency settings to inform treatment strategies and improve clinical outcomes. Material and Methods: Elderly patients diagnosed with COPD were included in this retrospective cohort study. Data on demographics, clinical presentations, laboratory results, comorbidities, and outcomes were collected. Biochemical measurements were performed via biochemical analyses and arterial blood gas analyses. Results: Among the 139 patients studied, 89 (64%) were male with a mean age of 75 years. The mortality rate was 7.92%. No significant differences were observed in age, sex distribution, or comorbidities between deceased and surviving patients. Lactate clearance and bilirubin levels did not significantly affect mortality. However, albumin levels were notably lower in deceased patients (p
