Abstract:
BACKGROUND : With low influenza vaccination rates among the chronically ill, approaches to increase these rates among risk patients with chronic obstructive pulmonary disease (COPD) are to be uncovered. METHODS : 120 COPD patients from Magdeburg filled out a questionnaire and were analyzed regarding the influenza vaccination status 2015/2016 or 2016/2017. Vaccinated and unvaccinated were compared in socio-epidemiological factors, the health belief model (HBM), self-efficacy (GESIS-ASKU), anxiety/depression (HADS-D) and disease processing (FKV-LIS). RESULTS : 62.5 % (n = 75) were vaccinated, 31.7 % (n = 38) unvaccinated, 5.8 % (n = 7) made no statement. In over or equal to 60-year-olds 76 % were vaccinated, in under 60-year-olds 42 % were vaccinated. 60 % (n = 72) knew to belong to a risk group. Unvaccinated indicated greater concern about side effects of the vaccination (p = .004) and drew a worse benefit-expense balance (p = .001). Unvaccinated were more often uncertain about the vaccination protection and the severity of influenza (p ≤ .001). Vaccinated were highly motivated to think about vaccination themselves and more often had a positive vaccination history (p = .001). COPD patients showed a lower self-efficacy than the reference group of the German general population (p = .000), vaccinated and unvaccinated did not differ (p = .418). No difference between vaccinated and unvaccinated was found in the processing of the disease and in depression and anxiety, but unvaccinated tended to give higher anxiety values. CONCLUSION : Measures should particularly target COPD patients under 60 years of age with a negative vaccination history and sensitize them as risk patients. Widespread uncertainties about the severity of influenza and vaccination protection should be addressed. It should be communicated that influenza vaccination does not lead to exacerbation. The vaccination recommendation should increasingly be made by pulmonologists.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

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.
