Objective: In this study, we aimed to determine the clinical differences between former and current smoker chronic obstructive pulmonary disease (COPD) patients. Material and Methods: Demographic characteristics, smoking history, emergency admissions and hospitalizations in the last year were questioned in patients with COPD admitted to the chest diseases outpatient clinic. The assistive devices they used such as oxygen concentrators and bilevel positive airway pressure (BIPAP) were recorded. Exercise capacity was assessed by 6-minute walk test, dyspnea perception by Modified Medical Research Council dyspnea scale, quality of life by St. George Respiratory Questionnaire, psychological symptoms by Hospital Anxiety Depression Questionnaire, comorbidity severity by Charlson Comorbidity Index (CCI). Mann-Whitney U test and the chi-square test were used to compare group data. Results: Of the 447 COPD patients, 111 (24.83%) continued to smoke. Former smokers were significantly older than current smokers (p=0.014). Current smokers exhibited significantly lower body mass index values (p=0.002). The amount of cigarette consumption (pack/year), the number of emergency admissions and hospitalizations in the last year was higher in current smokers (p=0.002, p<0.001, p=0.001). BIPAP and oxygen concentrator use, presence of cardiovascular disease and CCI score were higher in former smokers than in current smokers (p<0.05). Conclusion: The number of emergency visits and hospitalizations is higher in COPD patients who continue to smoke.

Amaç: Bu çalışmada, sigara içen ve sigara içmeyi bırakmış olan kronik obstrüktif akciğer hastalığı (KOAH) hastalarının klinik farklılıklarını belirlemeyi amaçladık. Gereç ve Yöntemler: Göğüs hastalıkları polikliniğine sevk edilen KOAH'lı hastalarda demografik özellikler, sigara içme öyküsü, son bir yıldaki acil başvurusu ve hastane yatışları sorgulandı. Oksijen konsantratörleri ve iki seviyeli pozitif hava yolu basıncı (BIPAP) gibi kullandıkları yardımcı cihazlar kaydedildi. Egzersiz kapasitesi 6 dakikalık yürüme testi, dispne algısı Değiştirilmiş Tıbbi Araştırma Konseyi dispne skalası, yaşam kalitesi St. George Solunum Hastalıkları Anketi, psikolojik semptomlar Hastane Anksiyete Depresyon Anketi, komorbidite şiddeti Charlson Komorbidite İndeksi [Charlson Comorbidity Index (CCI)] ile değerlendirildi. Grup verilerini karşılaştırmak için Mann-Whitney U testi ve ki-kare testi kullanıldı. Bulgular: 447 KOAH hastasından 111'i (%24,83) sigara içmeye devam etmekteydi. Sigarayı bırakanlar, sigara içenlerden önemli ölçüde daha yaşlıydı (p=0,014). Sigara içenlerde önemli ölçüde daha düşük beden kitle indeksi değerleri saptandı (p=0,002). Sigara tüketim miktarı (paket/yıl), son bir yıldaki acil başvurusu ve hastane yatış sayısı sigara içenlerde daha yüksekti (p=0,002, p<0,001, p=0,001). BIPAP, oksijen konsantratörü kullanımı, kardiyovasküler hastalık varlığı ve CCI skoru eski sigara içicilerinde mevcut sigara içicilerinden daha yüksekti (p<0,05). Sonuç: Sigara içmeye devam eden KOAH hastalarında acil başvurusu ve yatış sayısı daha yüksek seyretmektedir.
