Emergency department switching and duplicate computed tomography scans in patients with kidney stones.
The researchers measured the association between emergency department (ED) switching during a kidney stone episode and receipt of a repeat computed tomography (CT) scan. They found that 12% of patients who received a CT scan at their initial ED encounter had a revisit within 30 days of discharge. One-third of their revisits were made to a different ED than the iniital one. Duplicate CT scans were obtained at nearly 40% of all revisits. The risk of receiving a repeat CT was 12% higher if this revisit was made to a different ED. They concluded that their findings support the role of better health information exchange among providers to help reduce waste in the health-care system.

Evaluation of kidney stones with reduced-radiation dose CT: progress from 2011-2012 to 2015-2016-not there yet.
Researchers determined if the use of reduced-dose computed tomography (CT) for evaluation of kidney stones increased in 2015-2016 compared with that in 2011-2012. Use of reduced-radiation dose CT for evaluation of kidney stones has increased, but remains low; variability of radiation dose according to facility continues to be wide. National mean CT radiation exposure for evaluation of renal colic during 2015-2016 decreased relative to 2011-2012 values.
