PURPOSE: Chronic obstructive pulmonary disease (COPD) is a complex disease with extrapulmonary comorbidities, which often contribute to exacerbations. However, there are few studies to investigate impact of comorbidity on frequent severe exacerbations requiring hospitalization in COPD patients. Thus, we aimed to identify factors (including comorbidity) associated with recurrent hospital admissions in COPD patients with severe acute exacerbation (AE).
METHODS: A retrospective observational study was carried out in Samsung medical center (a 1,961-bed referral hospital in Seoul, Korea). We studied a total of 82 patients with severe AE between February 2012 and January 2014 and outcomes were evaluated for a year from the first admission day.
RESULTS: Of 82 patients, 31 patients (38%) developed recurrent severe AEs (median time to first exacerbation). In comorbidities, cardiovascular disease (P=0.041) were significantly higher in patients with recurrent severe AEs compared to those without recurrent severe AEs, while diabetes, asthma, lung cancer and tuberculosis destroyed lung were similar between two groups. In other clinical factors, lower forced expiratory volume in 1 second (P=0.006), home oxygen therapy (P=0.002) and long term oral steroid use (P=0.037) were significantly associated with recurrent severe AEs. In multivariate analysis, cardiovascular disease was an independent factor related to recurrent severe AE (OR: 3.10, P =0.046) There were no significant differences were found in hospital days, hospital and 1 year mortality between two groups.
CONCLUSIONS: Recurrent severe AEs of COPD was associated with comorbidity of cardiovascular disease as well as home oxygen therapy.
CLINICAL IMPLICATIONS: Comorbidity should be considered as a significant contributor to frequent severe AEs in COPD patients.
