Severe acute kidney injuries are becoming more common in the United States, rising 10 percent per year and doubling over the last decade, according to a retrospective study at the University of California, San Francisco (UCSF).
The study, to be published online this week in the Journal of the American Society of Nephrology, analyzed information from a national database that monitors all causes of hospitalizations and used this data to estimate the total number of acute kidney injuries in the United States that were severe enough to require a patient to be placed on dialysis.
The results showed that these injuries, caused by such incidents as major infections, trauma, complications following surgery and adverse reactions to drugs, increased by 10 percent per year from 2000 to 2009, from 222 to 533 cases per million people. The study also showed that the total number of deaths associated with acute kidney injury more than doubled during that time, from 18,000 in 2000 to nearly 39,000 in 2009.
“That was a staggering revelation of how increasingly common and how life-threatening acute kidney injury has become over the past decade in the United States,” said Raymond K. Hsu, MD, a UCSF nephrologist who led the research.
