RESUMEN
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.

Chronic obstructive pulmonary disease (COPD) is a common lung disease. There is a limited amount of nationwide data on COPD patients in Poland. This study aimed to characterize patients hospitalized with COPD in Poland in 2019 as well as to identify factors associated with the risk of in-hospital death and prolonged hospitalization among patients with COPD. This study is a retrospective database analysis. Data on patients hospitalized with COPD in Poland were obtained from the Nationwide General Hospital Morbidity Dataset. Data on all adults aged ≥40 years with a diagnosis of COPD from a physician (J44 code) were included in the analysis. Data were analyzed separately for patients hospitalized due to COPD (primary diagnosis) and patients with COPD as a comorbidity (secondary diagnosis). Completed medical records were available for 101,471 patients hospitalized with COPD (36.9% were females). Of those, 32% were hospitalized due to COPD. The mean age was 71.4 ± 9.7 years. The mean duration of hospitalization was 9.4 ± 11.4 days (median 7 days). Most of the COPD patients (89.3%) had at least one comorbidity. The in-hospital mortality rate was 6.8%. Older age, presence of cardiovascular diseases, and diseases of the genitourinary system (p < 0.05) were the most important factors associated with the risk of in-hospital death among patients hospitalized due to COPD.

INTRODUCTION: COVID19 is an infectious disease caused by SARS-CoV-2. Little is known on the impact of weather conditions on the transmission of COVID19. OBJECTIVES: We aimed to assess correlations between 6 different meteorologic parameters and the transmission dynamics of the COVID19 pandemic in 16 administrative regions (voivodeships) of Poland. PATIENTS AND METHODS: Data for analysis were obtained from epidemiologic reports of the Polish Ministry of Health. For each voivodeship, one synoptic station was selected to provide meteorologic data on daily maximum and minimum temperatures, variability of daily temperature, sunshine duration, relative humidity, and wind speed. The periods with significant weather impact were determined using multiple linear regression. Crosscorrelation function (CCF) and random forest models were used to assess correlations between meteorologic parameters and the incidence of COVID19 as well as the number of hospitalizations for COVID19. RESULTS: In all voivodeships, the incidence of new COVID19 cases correlated with relative humidity (CCF = 0.41), daily maximum temperature (CCF = -0.41), variability of daily temperature (CCF = -0.40), and sunshine duration (CCF = 0.35). For all parameters, a similar time lag of 10 to 14 days was noted. There were no significant correlations for wind speed in most voivodeships. The risk of hospitalization for COVID19 correlated with daily maximum temperature (CCF = -0.48; time lag, 10 days) and sunshine duration (CCF = -0.45; time lag, 10 days). CONCLUSIONS: The delayed effects of the meteorologic factors on the incidence of COVID19 and the risk of hospitalization for COVID19 were observed. In each voivodeship, the dynamics of COVID19 transmission was most strongly affected by relative humidity and daily maximum temperature.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the novel coronavirus. The role of environmental factors in COVID-19 transmission is unclear. This study aimed to analyze the correlation between meteorological conditions (temperature, relative humidity, sunshine duration, wind speed) and dynamics of the COVID-19 pandemic in Poland. Data on a daily number of laboratory-confirmed COVID-19 cases and the number of COVID-19-related deaths were gatheredfrom the official governmental website. Meteorological observations from 55 synoptic stations in Poland were used. Moreover, reports on the movement of people across different categories of places were collected. A cross-correlation function, principal component analysis and random forest were applied. Maximum temperature, sunshine duration, relative humidity and variability of mean daily temperature affected the dynamics of the COVID-19 pandemic. An increase intemperature and sunshine hours decreased the number of confirmed COVID-19 cases. The occurrence of high humidity caused an increase in the number of COVID-19 cases 14 days later. Decreased sunshine duration and increased air humidity had a negative impact on the number of COVID-19-related deaths. Our study provides information that may be used by policymakers to support the decision-making process in nonpharmaceutical interventions against COVID-19.
