What is it?
Readmission to the hospital within 30 days for patients who had pneumonia. Pneumonia is an infection in one or both lungs. It can be caused by bacteria, viruses or a fungus. Bacterial pneumonia is the most common type in adults. Pneumonia causes inflammation in the air sacs in your lungs, which are called alveoli. The alveoli fill with fluid or pus, making it difficult to breathe.
How's it measured?
Measured as a percent of patients readmitted to the hospital within 30 days of leaving the hospital for a serious lung infection.
