The number of bloodstream infections in intensive care units (ICUs) caused by tubes inserted into major blood vessels decreased significantly between 2001 to 2009, but unacceptably high rates of infection are still occurring for patients in other hospital units and for dialysis patients, government researchers say.

Central lines are tubes that are usually placed in the large veins of the neck or chest to deliver medicines and nutrition. Infections of these lines, which are largely preventable, can become serious problems, with death rates of 12-25%.

An estimated 18,000 ICU central-line infections were recorded in 2009, down from 43,000 in 2001, according to a report by the Centers for Disease Control and Prevention (CDC). This 58% decrease means that in 2009, between 3,000 and 6,000 deaths were prevented and as much as $414 million saved. And if the decrease in these ICU infections was steady from 2001 to 2009, as many as 27,000 lives and as much as $1.8 billion may have been saved.

(Note: These numbers are rough estimates. The 2001 figure of 43,000 infections could have been as low as 27,000 and as high as 67,000.)

According to the CDC, much of the decrease resulted from campaigns to improve techniques for managing the lines in ICUs, where they are most frequently used. Infections involving bacteria such as staphylococcus can be avoided with simple measures like washing hands, wearing sterile gowns and drapes, and following the proper techniques for inserting and maintaining the lines.

However, researchers noted that central line infections still occurred far too often, affecting 80,000 patients a year and killing at least 10,000. In addition, of the 350,000 patients who received dialysis in the U.S. in 2008, about 37,000 suffered central-line infections. Such infections are the second leading cause of hospital stays and death in people on dialysis after cardiovascular problems.

Peter Pronovost, MD of Johns Hopkins Hospital, a pioneer in patient safety, developed the simple "checklist" for using central lines in ICU patients, which was proven in a landmark study in the New England Journal of Medicine to cut the infection risk to close to zero.

You can read an abstract of the study here.

ProPublica, the investigative reporting group, is publishing a series on the quality of care the nation's 400,000 dialysis patients get, and it's not pretty. The basic conclusion:

"Taxpayers spend more than $20 billion a year to care for those on dialysis -- about $77,000 per patient, more, by some accounts, than any other nation. Yet the United States continues to have one of the industrialized world's highest mortality rates for dialysis care. ...

"At clinics from coast to coast, patients commonly receive treatment in settings that are unsanitary and prone to perilous lapses in care. Regulators have few tools and little will to enforce quality standards. Industry consolidation has left patients with fewer choices of provider. The government has withheld critical data about clinics' performance from patients, the very people who need it most. Meanwhile, the two corporate chains that dominate the dialysis-care system are consistently profitable, together making about $2 billion in operating profits a year."

The ProPublica reporters go on to say that: "One reason the system's problems have evolved out of the health care spotlight is that kidney failure disproportionately afflicts minorities and the dispossessed."

And here is part 2 of the series, which opens with a horrifying story about a woman who lost a quarter of her blood because the dialysis tube delivering the cleansed blood back to her body became dislodged and the technicians didn't notice until it was too late.

Here is one more piece of it, an important footnote about how the ProPublica reporters got the hard data on patient deaths that the government keeps hidden from the public.
