Abstract：
Poland is a country with a high burden of COPD and its risk factors. This population-wide and geospatial study on COPD in Poland, aimed to analyze changes in hospitalizations of patients with a diagnosis of COPD between 2006 and 2019 as well as to identify changes in the demographic characteristics of patients hospitalized with COPD. This is a retrospective analysis of hospital discharge records of patients with a diagnosis of COPD (ICD-10 code J44 and age 40 and over), hospitalized in Poland between 2006 and 2019. Data were analyzed separately for all patients hospitalized with COPD (primary and secondary diagnosis), for patients admitted due to COPD (primary diagnosis) and patients hospitalized with COPD as a comorbidity (secondary diagnosis). Between 2006 and 2019, a total of 1,663,420 hospital admissions of patients with COPD were reported. Between 2006 and 2019, the annual number of patients hospitalized due to COPD decreased by 53.8%, including 57.3% among men and 46.6% among women. The number of patients hospitalized with COPD as comorbidity increased by 35.8%. The lowest hospital admissions rate was in north-western Poland and the highest in north-eastern Poland. Among patients admitted due to COPD, the percentage of women increased from 32.6% to 37.7%. The percentage of patients admitted due to COPD and living in rural areas decreased from 51.2% in 2006 to 40.8%in 2019. This study provided data on changes in sociodemographic characteristics of hospitalizations of patients with a diagnosis of COPD, including overall reduction in COPD admissions but an increase in COPD burden among women.
摘要：
波兰是COPD及其危险因素负担较高的国家。这项关于波兰COPD的全人群和地理空间研究，旨在分析2006年至2019年间诊断为COPD的患者的住院情况变化,并确定COPD住院患者的人口学特征变化.这是对诊断为COPD（ICD-10代码J44和40岁及以上）的患者的出院记录的回顾性分析，2006年至2019年期间在波兰住院。分别分析所有COPD住院患者的数据（主要和次要诊断），对于因COPD而入院的患者（主要诊断）和因COPD而住院的患者（次要诊断）。在2006年至2019年期间，共报告了1,663,420例COPD患者入院。在2006年至2019年期间，因COPD住院的患者人数减少了53.8%，其中男性占57.3%，女性占46.6%。合并COPD的住院患者数量增加了35.8%。住院率最低的是波兰西北部，最高的是波兰东北部。在因COPD入院的患者中，妇女的百分比从32.6％增加到37.7％。因COPD入院并居住在农村地区的患者比例从2006年的51.2%下降到2019年的40.8%。这项研究提供了诊断为COPD的患者住院的社会人口统计学特征变化的数据，包括COPD住院人数总体减少,但女性COPD负担增加.
