Treating Blood Infections Tops Annual Hospital Cost Increases


WASHINGTON—The hospital costs for treating septicemia increased by an average of nearly 12 percent each year from 1997 to 2007, according to the latest News and Numbers from the Agency for Healthcare Research and Quality.

Treating this potentially deadly blood infection increased from $4.1 billion in 1997 to $12.3 billion in 2007.

After adjusting for inflation, the federal agency also found other conditions that saw high annual increases in hospital costs in each of the 11 years between 1997 and 2007:

  • Osteoarthritis, up 9.5 percent each year ($4.8 billion to $11.8 billion)
  • Back problems, up 9.3 percent each year ($3.5 billion to $8.5 billion)
  • Acute kidney failure, up 15.3 percent per year ($1 billion to $4 billion)
  • Respiratory failure, up 8.8 percent per year ($3.3 billion to $7.8 billion)

Overall, the most important driver of cost increases in the hospital was the greater intensity of services provided during a hospital stay, which grew 3.1 percent per year during from 1997 to 2007. This greater intensity of services accounted for 70 percent of the total increase in hospital costs.
