Results of GE Healthcare-supported economic modeling of a retrospective meta-analysis of published literature were presented today at the SCAI 2014 Scientific Sessions in Las Vegas, NV. The model showed that iso-osmolar contrast media was associated with lower overall cost – nearly $700 savings per patient - when compared to low-osmolar contrast media in regard to contrast-induced acute kidney injury (CI-AKI).
“Contrast-induced acute kidney injury has major implications including morbidity and health resource utilization,” said Swapnil Hiremath, MD, Assistant Professor Medicine in the Division of Nephrology at the University of Ottawa and lead author of the study. “This study provides complementary and supportive CI-AKI data to the recently published meta-analyses by McCullough and Dong comparing contrast-induced nephrotoxicity of iso-osmolar and low-osmolar contrast media and ascribes an economic value to those analyses.”
About the Study
A systematic review and meta-analysis was conducted to estimate the risk of acute kidney injury after use of iso- and low-osmolar contrast media. A Markov model was then created, taking into account peri-procedural risks, the differential risk of acute kidney injury, the need for dialysis and subsequent mortality risk as well as cost associated with the contrast media itself and treatment for downstream clinical events.
The model showed that use of iso-osmolar contrast resulted in a higher quality adjusted life expectancy (29.19 versus 28.87 quality adjusted life years), in addition to nearly $700 savings per patient. This result was robust across most sensitivity analyses, including cost of contrast media, baseline risk of acute kidney injury, volume of contrast used, risk of dialysis. The exception was the sensitivity analysis with the differential risk of acute kidney injury with iso-osmolar versus low-osmolar contrast media.
“This study shows GE’s commitment to the continued advancement of scientific knowledge of iodinated contrast media choice in the interventional field, specifically highlighting health economics,” said Jan Makela, General Manager, Core Imaging, GE Healthcare Life Sciences. ”We were particularly pleased to find the model reported cost savings for iso-osmolar contrast even when taking into account upfront cost of contrast.”
