factors associated with in-hospital death among pneumonia patients in us hospitals from 2016~2019

Background  pneumonia is one of the leading causes of hospital admission in the united states with a global health burden of about 6.8 million hospitalizations and 1.1 million deaths in patients over 65 years old in 2015. this study aimed to identify possible patient and hospital-related risk factors for in-hospital pneumonia death across us hospitals.methods  the national inpatient sample (nis) was used to identify nationwide pneumonia patients (n = 374 766, weighted n = 1 873 828) from 2016 to 2019. we examined the characteristics of the study sample and their association with in-hospital death. multivariate survey logistic regression models were used to identify risk factors.results  during the study periods, in-hospital death rates continuously decreased (2.45% in 2016 to 2.19% in 2019). descriptive statistics showed that patient and hospital factors had varied in-hospital death rates. survey logistic regression results suggested that male, very low income, non-medicare, government hospitals, rural hospitals, and specific hospital regions were associated with higher in-hospital death rates than their reference groups.conclusion  socioeconomic factors, including income and insurance, are associated with pneumonia mortality. census region, hospital ownership, and rural location are also related to in-hospital mortality. such findings in underserved, impoverished, and rural areas to identify possible health disparities.
