Association Between Comorbid COPD and Prognosis of Patients Admitted to ICU for Non-COPD Reasons

Comorbid COPD increased the risk of 28-day mortality among patients admitted to the ICU for non-COPD reasons, especially for those admitted to the cardiac surgery recovery unit.

A retrospective cohort study was performed using data extracted from a freely accessible critical care database (MIMIC-III).

Adult (≥18 years) patients of first ICU admission in the database were enrolled as study participants but those with a primary diagnosis of COPD were excluded.

The primary endpoint was 28-day mortality after ICU admission and multivariable Cox regression analyses were employed to assess the associations between COPD comorbidity and the study endpoints.

Different adjusting models including a propensity score were used to adjust potential confounders.
