About 50% of the patients are undiagnosed. COPD patients often have CO which may lead to hospitalization[2].To analyze the frequency of COPD as CO among hospitalised patients, the number of undiagnosed COPD patients, COPD patients (PC) and patients without COPD (PwC) in regards of the cause of hospitalization, and duration of hospitalization for PC and PwC as CO.Aalborg University Hospital covers all medical and surgical specialities. A one day cross-sectional study was performed on patients > 18 years of age. A spirometry was performed. Smoking habits, prior lung function measurements, prescribed lung medicine were recorded. The final diagnosis was registered after one month.583 patients were admitted to the participating units. 147 couldn't participate, 47 didn't wish to participate. 111 weren't available at the time of the examination. 12 were excluded. 215 patients participated, 28% (61/215) suffered from COPD. 77% (47/61) were diagnosed at our examination. 36,1%(22/61) of the PC were admitted with infections, the majority non-pulmonary. The admission period was not significantly longer for PC as comorbidity (mean 13.03 days) compared to PwC (mean 12.1 days), (p=0.24).28% of hospitalised patients suffered from COPD.77% were diagnosed at our examination.PC were primarily admitted with infectious diseases.There was no significant difference in length of stay in hospital between PC and PwC as comorbidity.1) Loekke A et al.
