Researchers performed a retrospective analysis of National Hospital Discharge Surveys for adults with urinary catheter placements. CAUTIs were identified through ICD-9-CM code tracking.
Out of 70.4 million catheterized patients, 3.8 million developed a CAUTI over the 10-year study period. Average rates of CAUTI decreased from 9.4 percent of catheterizations in 2010 to 5.3 percent of catheterizations in 2010.
Mortality and length-of-stay associated with CAUTIs also decreased with 5.4 percent mortality and nine-day length-of-stay declining to 3.7 percent mortality and a seven-day length-of-stay.
The reasons for these declines were not immediately apparent.
