SESSION TITLE: Wednesday Electronic Posters 2 SESSION TYPE: Original Inv Poster Discussion PRESENTED ON: 10/23/2019 09:45 AM - 10:45 AM PURPOSE: Since 2011, the Global Initiative for Obstructive Lung Disease (GOLD) has included symptom burden in the multidimensional assessment of patients with chronic obstructive pulmonary disease (COPD). The prevalence and severity of 24-hour respiratory symptoms in COPD patients from Central Eastern Europe (CEE) is less known. METHODS: This was a multinational cross-sectional study (NCT03031769) in stable COPD patients from 11 countries. Out of 2162 patients enrolled, 1422 were from 5 CEE countries: Romania (RO) n=406, Poland (PL) n=356, Serbia (SB) n=250, Bulgaria (BG) n=210, and Slovakia (SK) n=200. All patients had COPD with duration of at least 1 year. Stable disease was defined as no exacerbation history or changes in maintenance treatment in the last 2 months before enrolment. Respiratory symptoms over the last 24 hours were evaluated using specific questionnaires: Night-time Symptoms of COPD Instrument-NiSCI, Early Morning Symptoms of COPD Instrument-EmSCI and the derivative questionnaire for stable patients from Evaluating Respiratory Symptoms in COPD (E-RS™:COPD) for daytime symptoms. COPD Assessment Test (CAT) was also used. RESULTS: The percentages of patients reporting at least one respiratory symptom in each period of the day in each country were as follows. Night-time (NT) symptoms: BG 84.8%, PL 61.8%, RO 71.4%, SK 77.5%, SB 66.8%; early morning (EM) symptoms: BG 93.8%, PL 89.6%, RO 87.7%, SK 92.0%, SB 80.4%; day-time (DT) symptoms: BG 99.5%, PL 94.7%, RO 92.6%, SK 95.5%, SB 90.8%. Across countries, mean severity scores between 0.6 and 1 for NT and between 0.8 and 1.1 for EM indicated mild symptoms. Mean severity scores for DT symptoms were: BG 14.7, PL 13.2, RO 12.5, SK 11.4 and SB 9.8 – out of a maximum of 40, with higher scores representing more severe symptoms. The impact of symptoms was most apparent for night awakenings (BG 39.5%, PL 28.7%, RO 36.0%, SK 34.0%, SB 27.2%) and tiredness during the day (BG 81.0%, PL 70.7%, RO 79.0%, SK 60.0%, SB 66.2%). Mean CAT scores ranged from 15 in SK and SB to almost 17 in PL, 19 in RO, and 19.2 in BG. The distribution of low burden (A/C) vs. high burden (B/D) symptom categories by GOLD 2017 report differed at country level: 27.2% vs. 72.8% in BG, 35.9% vs. 64.1% in PL, 27.6% vs. 72.4% in RO, 32.5% vs. 67.5% in SK and 48.4% vs. 51.6% in SB. The majority of patients received COPD maintenance treatment: 98.8% in PL and SB, 99% in RO and SK and 100% in BG. CONCLUSIONS: Despite regular treatment, symptoms place a high burden in stable COPD patients from CEE countries. Symptoms are variable and impact daily life of patients. CLINICAL IMPLICATIONS: Comprehensive assessment of respiratory symptoms can prove beneficial towards a more personalized treatment of patients with COPD.
