Abstract

Background: It is of utmost importance to identify populations with an elevated risk for COVID-19 and the factors influencing its outcomes. The present study aimed to investigate factors affecting mortality and length of stay (LOS) among COVID-19 patients in the hospitals of East Azerbaijan province, Iran, during 15 months of this pandemic.

Study design: The present study followed a retrospective cohort design.

Methods: This retrospective study was conducted using data in the integrated syndromic surveillance system (ISSS) on patients admitted to the hospitals from February 21, 2020, to April 11, 2021. The association between variables of interest and death, as well as LOS, was investigated via multiple logistic regression and multiple linear regression analyses.

Results: In total, 24 293 inpatients with a mean age of 54.0 ± 19.4 years were included in this study. About 15% of them lost their lives, whose mean age was 69.0 ± 14.6 years, significantly higher than the recovered ones (P < 0.001). Factors, such as above 49 years of age (P < 0.001), male gender (OR = 1.17; 95% CI: 1.08-1.26), and having chronic diseases (OR = 1.32; 95% CI: 1.22-1.42), were correlated with patient mortality. In addition, having chronic diseases (Beta = 0.06; 95% CI: 0.03-0.08) was associated with higher LOS in hospitals.

Conclusion: In conclusion, older patients were at a higher risk of mortality and prolonged hospitalization. Furthermore, patients' underlying diseases could cause a severe form of COVID-19, which can lead to death and increase patients' LOS.

伊朗东阿塞拜疆医院COVID-19患者死亡率及住院时间相关因素调查
背景:确定COVID-19高危人群及其影响结果的因素至关重要。本研究旨在调查在此次大流行的15个月期间,伊朗东阿塞拜疆省医院的COVID-19患者的死亡率和住院时间(LOS)的影响因素。研究设计:本研究采用回顾性队列设计。方法:利用综合综合征监测系统(ISSS)的数据,对2020年2月21日至2021年4月11日住院的患者进行回顾性研究。通过多元逻辑回归和多元线性回归分析,研究了感兴趣的变量与死亡以及LOS之间的关系。结果:共纳入住院患者24 293例,平均年龄54.0±19.4岁。病死率约15%,平均年龄(69.0±14.6)岁,显著高于痊愈者(P < 0.001)。49岁以上(P < 0.001)、男性(OR = 1.17;95% CI: 1.08-1.26),并且患有慢性疾病(OR = 1.32;95% CI: 1.22-1.42),与患者死亡率相关。此外,患有慢性疾病(Beta = 0.06;95% CI: 0.03-0.08)与医院较高的LOS相关。结论:老年患者死亡风险较高,住院时间延长。此外,患者的基础疾病可能导致严重形式的COVID-19,这可能导致死亡并增加患者的LOS。
