Predictors of mortality in COPD exacerbation include quality of life, marital status, depression, comorbidity, and prior hospital admissions. These factors offer crucial prognostic information for patients hospitalized with COPD.

Area of Science:

  • Pulmonary Medicine
  • Clinical Epidemiology

Background:

  • Acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD) is a significant cause of hospitalization and mortality.
  • Identifying prognostic factors is crucial for managing COPD patients and improving outcomes.

Purpose of the Study:

  • To identify clinical, socioeconomic, and functional variables associated with mortality in patients hospitalized for acute exacerbation of COPD.

Main Methods:

  • A prospective cohort study was conducted with 135 consecutive patients hospitalized for COPD exacerbation.
  • Data collected included clinical, spirometric, gasometric, socioeconomic, comorbidity, functional status, depression, and quality of life variables.
  • Mortality was assessed at 180 days, 1 year, and 2 years post-hospitalization.

Main Results:

  • Overall mortality at 2 years was 35.6%.
  • Bivariate analysis showed higher mortality in older patients, women, and unmarried individuals.
  • Multivariate analysis identified the St. George's Respiratory Questionnaire (SGRQ) activity subscale, comorbidity (Charlson index), depression (Yesavage Scale), prior hospital readmission, and marital status as independent predictors of mortality.

Conclusions:

  • Quality of life, marital status, depressive symptoms, comorbidity, and prior hospital admission are significant prognostic indicators in COPD patients.
  • These factors can aid clinicians in assessing prognosis and guiding patient management after hospitalization for COPD exacerbation.
