Mortality Risk Factors Among Hospitalized Older Patients With Covid-19

Background: the coronavirus disease 2019 (covid-19) is an infectious disease with ahigh mortality rate among older people.objective: the current study aims to investigate the death rate and related factors amonghospitalized older patients with covid-19 in qazvin, iran.methods: in this descriptive and cross-sectional study, 430 older inpatients with covid-19(mean±sd age: 72.83±8.81) admitted to two hospitals in qazvin, iran were randomly selected.their information was extracted from their electronic health records. independent t-test, chisquaretest, and multivariate logistic regression analysis were used for the data analysis.findings: hypertension (n=234, 54.4%), diabetes mellitus (n=148, 34.4%), andcardiovascular diseases (n=127, 29.4%) were the most prevalent comorbidities. dyspnea(n=300, 69.8%), cough (n=232, 54.0%), fever (n=186, 43.3%), and general malaise (n=168,39.1%) were the most frequent clinical symptoms. there was in-hospital mortality in 108(25.1%) older inpatients. multivariate regression results showed that the risk of in-hospitaldeath was significantly related to the inpatients’ age (or=1.037, 95%ci=1.007-1.068),white blood cell count (or=1.187, 95%ci=1.114-1.264), hemoglobin level (or=0.812,95%ci=0.720-0.914), platelet count (or=0.993, 95%ci=0.989-0.996), and oxygensaturation level (or=0.950, 95%ci=0.967-0.932) at the time of admission.conclusion: older age, white blood cell count, hemoglobin level, oxygen saturationlevel, and platelet count are predictors of death among older inpatients with covid-19.identification of these risk factors can assist the healthcare providers for timely interventionfor the prevention of death.
