Abstract
Introduction Pneumonia is one of the most common causes of hospital admissions in the United States and remains a major cause of death. However, less is known regarding the mortality burden from pneumonia in the United States and how this burden has changed over time. Methods Death rates from causes related to pneumonia were determined using the CDC Wide-ranging Online Data for Epidemiologic Research (WONDER) data from 1999-2019. Pneumonia deaths were calculated for the overall population as well as for sociodemographic subgroups. We also analysed changes in death rates over time. Results Overall, 2.1% of total US deaths during the period between 1999 and 2019 were due to pneumonia (2.6% in 1999 and 1.5% in 2019). Mortality declined over time for both men and women, and across most age cohorts, as well as all racial, urbanisation, and regional categories. Rates of pneumonia deaths were higher among males as compared to females (age-adjusted mortality rate ratio (AAMRR) = 1.35; 95% CI: 1.34-1.35). Compared to White Americans, Black Americans had the highest pneumonia-related mortality rates of any racial group (AAMRR = 1.11; 95% CI: 1.10-1.11). Conclusions Rates of pneumonia-related death have decreased in the United States in recent decades. However, significant racial and gender disparities remain, indicating the need for more equitable care.
