The Silesian Voivodeship is the region with the highest population density in Poland, three times higher than the national average. These are important circumstances that may favor the transmission of the SARS-CoV-2 virus and, due to the severe course of the disease in many patients, contribute to overloading the healthcare system.
The aim of the study was to evaluate the temporal and territorial variability of hospitalized morbidity and in-hospital mortality in COVID-19 patients treated in the study region.
The research was an epidemiological descriptive study. Secondary epidemiological data were obtained from the registry of the Health Department of the Silesian Voivodeship Office in Katowice. Crude and standardized hospitalized morbidity rates, as well as COVID-19 in-hospital mortality, were calculated. Results were presented in particular poviats and subsequent months of the 2020 year. The capabilities of the ArcGIS 9.2 geographic information system and Statistica 13.3 software were used.
The largest number of patients hospitalized due to COVID-19 and the number of deaths occurred in autumn and spring, in both periods in-hospital mortality was over 24%. The poviats with the highest standardized hospitalized prevalence rate were located in the southern part of the Silesian Voivodeship. The highest in-hospital mortality (exceeding 24%) was recorded in Gliwice, Mysłowice, Tychy, Bytom and in the Lubliniec poviat. Older people (65+), usually with diagnosed comorbidities, including chronic respiratory and cardiovascular diseases, died more often.
The highest number of patients and deaths due to COVID-19 occurred in autumn. A significant territorial diversification of hospitalized morbidity and in-hospital mortality was demonstrated, the worst situation concerned densely populated poviats and cities. Worse prognosis applied to older patients with comorbidities.
西里西亚省是波兰人口密度最高的地区，是全国平均水平的三倍。这些都是可能有利于 SARS-CoV-2 病毒传播的重要因素，并且由于许多患者的疾病严重程度，导致医疗保健系统负担过重。
本研究旨在评估 COVID-19 患者在研究区域住院发病率和院内死亡率的时间和地域变异性。
本研究为描述性流行病学研究。从卡托维兹西里西亚省卫生部门的卫生局登记处获得了二级流行病学数据。计算了粗发病率和标准化住院发病率以及 COVID-19 的院内死亡率。结果以特定的 poviat 和 2020 年以后的月份呈现。使用了 ArcGIS 9.2 地理信息系统和 Statistica 13.3 软件的功能。
因 COVID-19 住院的患者人数最多，死亡人数最多发生在秋季和春季，两个时期的院内死亡率均超过 24%。标准化住院发病率最高的 poviat 位于西里西亚省的南部。住院死亡率最高（超过 24%）的是格利维采、迈索维采、琴斯托霍瓦、比托姆和卢布林涅茨 poviat。老年人（65 岁以上），通常患有慢性呼吸道和心血管疾病等合并症，死亡的可能性更高。
COVID-19 患者和死亡人数最多的是秋季。住院发病率和院内死亡率的地域差异很大，情况最严重的是人口密集的 poviat 和城市。预后较差的是患有合并症的老年患者。
