The situation regarding COVID‑19 in Poland is rapidly evolving. Because of this, it is important to investigate COVID‑19 mortality and its predictors in one of the most densely populated regions of the country, Silesia Province.
The goals of this study were to assess in‑hospital mortality due to COVID‑19 and the impact of sex, age, and coexisting diseases on the risk of death.
The data analysis was based on discharge reports of patients with COVID‑19 hospitalized between March and June 2020 in all hospitals in the region. Age, sex, hospital discharge status, and the presence of coexisting diseases were abstracted from the charts.
In a group of 2830 in‑patients with COVID‑19, 325 died during hospitalization. COVID‑19 deaths were associated with male sex (odds ratio [OR], 1.52; 95% CI, 1.17-1.96), older age (OR, 6.11; 95% CI, 4.5-8.31), and the presence of 3 or more coexisting diseases (OR, 4.78; 95% CI, 3.52-6.49). The most prevalent comorbidities were chronic cardiovascular and respiratory diseases.
The estimated in‑hospital fatality rate for COVID‑19 was 11.5%, which is lower than the average COVID‑19 fatality rate in other European countries. The risk of in‑hospital death was associated with sex, age, and the number of coexisting diseases, such as chronic cardiovascular and respiratory diseases.
波兰的 COVID-19 疫情形势瞬息万变。因此，研究 COVID-19 死亡率及其在该国人口最密集的地区之一——西里西亚省的预测因素非常重要。
本研究旨在评估 COVID-19 住院患者的院内死亡率，以及性别、年龄和并存疾病对死亡风险的影响。
数据分析基于 2020 年 3 月至 6 月期间该地区所有医院 COVID-19 住院患者的出院报告。从图表中提取年龄、性别、医院出院状况和并存疾病的存在情况。
在 2830 例 COVID-19 住院患者中，有 325 例在住院期间死亡。COVID-19 死亡与男性（比值比 [OR]，1.52；95%置信区间，1.17-1.96）、年龄较大（OR，6.11；95%置信区间，4.5-8.31）和存在 3 种或更多并存疾病（OR，4.78；95%置信区间，3.52-6.49）有关。最常见的合并症是慢性心血管和呼吸系统疾病。
COVID-19 的院内估计死亡率为 11.5%，低于其他欧洲国家 COVID-19 的平均死亡率。住院死亡的风险与性别、年龄和并存疾病（如慢性心血管和呼吸系统疾病）的数量有关。
