• Pneumonia, asthma, and acute bronchitis were the most common conditions that required hospital care in 2009, followed by mood disorders (depression and bipolar disorder). • Children represented one out of every six hospital stays, and total hospital charges for children were $33.6 billion, or 9 percent of total hospital costs in 2009. About 72 percent of children in hospitals were newborns and infants under 1 year.• Compared with all hospitalizations in 2009, a child’s average hospital stay was shorter (3.8 days versus 4.6 days) and less expensive ($5,200 versus $9,200).
