Pneumonia in older adults.

PURPOSE OF REVIEW: The purpose of this review is to address the relevant issues surrounding older adults with community-acquired pneumonia (CAP) today. RECENT FINDINGS: Approximately 1 million people >65 years have CAP in the US per year, which is more than previously reported (or realized). Older adults are vulnerable to the increasing prevalence of viral CAP, as the SARS-CoV-2 pandemic emphasizes, but pneumococcus is still the most common pathogen to cause CAP. Racial disparities continue to need to be addressed in order to improve early and late outcomes of older adults with CAP. SUMMARY: The epidemiology of CAP, specifically for older adults is changing. More recent pathogen incidence studies have included culture, as well as newer microbiological methods to determine etiology. Current disparities among disadvantaged populations, including African-Americans, result in more comorbidities which predisposes to more severe CAP. However, outcomes in the hospital between races tend to be similar, and outcomes between age groups tends to be worse for older compared to younger adults. Finally, the cost of CAP is significant compared to diabetes mellitus, myocardial infarction and stroke.
