RESUMEN
BACKGROUND: The objective of this study is to assess anxiety, depression and panic disorders among patients diagnosed with COPD and to investigate their correlation with disease severity, quality of life as well as tobacco use. METHODS: An observational study was performed between January and September 2014 among 60 patients diagnosed with COPD. COPD staging according to GOLD criteria, while anxiety and depression were assessed using Hospital Anxiety and Depression Scale and panic attacks were evaluated based on ICD 10 criteria. RESULTS: Almost 40% of the sample were smokers, the medium packs-years was 34.3 and the medium Fagerstrom score was 7.5. Overall, mean Modified Medical Research Council Dyspnea Scale (mMRC) was 2.86, mean COPD Assessment Test (CAT) score was 21.75 and study participants had 1.93 COPD exacerbations/year. Mean distribution of anxiety and depression symptoms scores among COPD subjects was 10.65 ± 3.5 and 9.93 ± 3.8, respectively. Smokers and ex-smokers had similar scores with regard to anxiety, depression or the presence of panic attacks. The results of the bivariate correlations indicated associations between anxiety, depression, panic attacks and disease severity, as well as poor quality of life of patients with COPD, regardless of their current tobacco use status. CONCLUSIONS: In conclusion, the results of this study indicate that anxiety, depression and panic attacks were constant characteristics among COPD patients- regardless of their current tobacco use.
