Impact of Increased Chest CT Utilization on the Diagnosis of Pneumonia in Older Adults: A Population-Based Study of 930,654 Individuals.

ABSTRACT:

Objective

The trends in chest computed tomography (CT) utilization among patients with pneumonia and its association with pneumonia incidence and mortality remain unclear. This study aimed to investigate these trends and their associations in older adults.

Materials and methods
