In the United States, two common conditions caused by hospital-acquired infections killed 48,000 people and ramped up health care costs by $8.1 billion in 2006 alone, according to a recent study.
This is the largest nationally representative study of the toll taken by sepsis and pneumonia, two conditions often caused by deadly microbes, including the antibiotic-resistant bacteria MRSA.
Such infections can lead to longer hospital stays, serious complications and even death.
Researchers analyzed 69 million discharge records from hospitals in 40 states and identified two conditions caused by health care-associated infections: sepsis, a potentially lethal systemic response to infection and pneumonia, an infection of the lungs and respiratory tract.
