Mental disorders in chronic obstructive pulmonary diseases.

Area of Science:

• Pulmonary Medicine
• Psychiatry
• Epidemiology

Background:

• Chronic obstructive pulmonary disease (COPD) is frequently associated with underdiagnosed anxiety and depression.
• The impact of anxiety and depression on severe exacerbations and subsequent hospitalizations in COPD patients remains under-researched.

Purpose of the Study:

• To investigate the association between anxiety/depression and severe exacerbations leading to hospitalization in COPD patients.
• To quantify the risk of hospitalization in COPD patients with diagnosed anxiety or depression.

Main Methods:

• A prospective cohort study involving 512 primary care COPD patients in rural Spain (2012-2014).
• Patients were assessed using the Hospital Anxiety and Depression Scale (HADS).
• Logistic regression analysis was employed to determine the association between anxiety/depression and severe exacerbation-related hospitalization.

Main Results:

• The initial prevalence of anxiety/depression was 15.6%.
• Patients with anxiety/depression showed higher hospitalization rates (17.5% year 1, 18.8% year 2) compared to the general cohort (8.2% year 1, 11.3% year 2).
• Anxiety/depression diagnosis nearly doubled the risk of hospitalization (OR = 1.94, p < .041).

Conclusions:

• Anxiety and depression are significantly associated with an increased risk of hospitalization in COPD patients.
• Further intervention studies are warranted to explore the impact of managing anxiety and depression on COPD hospitalization rates.
