Background And Aims:
Globally, chronic obstructive pulmonary disease (COPD) is one of the main causes of illness and death. Understanding the problem with respect to these factors is essential to finding a solution. Therefore, this study aimed to determine time to death and its predictors among outpatients with chronic obstructive pulmonary disease followed up in northwestern Ethiopia.
Methods:
A retrospective cohort study design was applied to collect relevant information on time to death from the medical patient's charts of 248 outpatients with COPD under follow-up at the UGRH. The information was explored using log-rank tests and Kaplan‒Meier plots. We used the Cox PH model for the time to death of outpatients with COPD.
Results:
Out of 248 COPD patients treated at UoG from January 1, 2020 to December 30, 2022, 82 (33.1%) patients died. The study population consisted of 248 patients who received COPD drug treatment during follow-up, of whom 148 (59.7%) were male, and 145 (58.5%) resided in urban areas.
Conclusion:
The Cox proportional hazards (PH) model identified sex, occupation, comorbidities, age, HIV status, weight, marital status, and smoking as risk factors for time to death.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
