Study suggests that Benvenue Medical’s Kiva system offers cost and resource savings for hospitals


Benvenue Medical’s Kiva vertebral compression fracture treatment system resulted in “substantial” cost and resource savings in the hospital setting over balloon kyphoplasty, according to an economic analysis published online in Pain Physician.

“Traditional procedures for treating vertebral compression fractures, such as vertebroplasty and balloon kyphoplasty, have been well documented to be safe, effective and cost efficient,” said Wayne J Olan, director of minimally invasive and endovascular neurosurgery at the George Washington University Medical Center, USA, and author of the study. “This study shows that the Kiva system is a further improvement in terms of both patient care and cost-effectiveness. The more than 30% reduction in adjacent-level fractures shown in the KAST trial with Kiva translates directly to fewer reoperations for the patient and reduced costs for the hospital relative to balloon kyphoplasty.”

The study analysed clinical data from the KAST study (which was conducted under an investigational device exemption granted by the US Food and Drug Administration), augmented with unit-cost data from the published literature. The vertebral compression fracture surgery, device and other medical costs were compared between Kiva and balloon kyphoplasty. Study authors concluded use of the Kiva would result in a direct medical cost saving of US$1,118 per patient and US$280,876 per hospital.

“In today’s healthcare environment, new technology must both improve patient outcomes and add economic value for our facility,” said J. Kevin McGraw, MD, Medical Director Interventional Radiology at Riverside Methodist Hospital, USA. “This study clearly demonstrates actual cost savings of using Kiva rather than balloon kyphoplasty in the long term. Not only does Kiva provide improved patient outcomes but now we know Kiva is also cost-effective.”

Robert K Weigle, chief executive officer of Benvenue Medical, said, “Along with improving clinical outcomes and increasing patient satisfaction, we now know the Kiva system provides significant cost savings for hospitals during a pivotal time when healthcare decision makers must optimise allocation of limited resources.”
