Pneumonia is an infection of the lungs. It can be caused by bacteria, a virus, or both. Pneumonia can cause difficulty breathing, coughing, fever and pain. For some people, pneumonia can be fatal.
Research shows that patients with pneumonia do better when their healthcare team takes certain steps. These steps include evaluating whether a patient needs the pneumonia vaccine and providing it if necessary.
The U.S. Department of Health and Human Services' Centers for Medicare and Medicaid Services (CMS) collects data on measures related to the care of patients who had pneumonia.
