Objective: This study aimed to assess the mortality rate of patients with chronic obstructive pulmonary disease (COPD) in Chonburi hospital.
Methods: Retrospective descriptive cross-sectional study was conducted using medical records of patients with COPD in Chonburi hospital during April 2023 to March 2024.
Results: There were 293 patients with COPD, the deaths were recorded in 21 patients. The mortality rate was 7.2%. Of 21 patients, there were 42.8%, 23.8%, 23.8%, 4.8% and 4.8% of patients died from exacerbation of COPD (ECOPD), pneumonia, sepsis, acute heart failure and prostate cancer retrospectively. Three significant risk factors associated with mortality were chronic kidney disease, low lung function and invasive mechanical ventilation. Patients with chronic kidney disease were 3.56 times more likely to die than those without chronic kidney disease (p-value 0.02). Patients with FEV1 ≥ 50% predicted were 3.12 times and patients with invasive mechanical ventilation were 3.22 times more likely to die compared to those with FEV1 > 50% predicted (p-value0.02) and those without invasive mechanical ventilation (p-value 0.04).
Conclusions: The overall mortality rate was 7.2% in COPD patients in Chonburi hospital. The main cause of death was ECOPD. Chronic kidney disease, severe airway obstruction and invasive mechanical ventilation were risk factors associated with increased mortality in these patients.
