title: Therapeutic Interchange of Clevidipine For Sodium Nitroprusside in Cardiac Surgery.
abstract: BACKGROUND
  Generic price inflation has resulted in rising acquisition costs for sodium nitroprusside (SNP), an agent historically described as the drug of choice for the treatment of perioperative hypertension in cardiac surgery.
  
  
  OBJECTIVE
  To describe the implementation and cost avoidance achieved by utilizing clevidipine as an alternative to SNP in cardiac surgery patients at a 520-bed community teaching hospital that performs more than 300 cardiac surgeries each year.
  
  
  METHODS
  A multidisciplinary team inclusive of anesthesiologists, intensivists, pharmacists, and surgeons collaborated to develop a therapeutic interchange for SNP in cardiac surgery patients. Consistent with current guidelines for therapeutic interchange, the goal was to encourage a less expensive alternative that was demonstrated to be at least therapeutically equivalent to SNP based on data derived from clinical trials published in peer-reviewed literature. A comprehensive literature review identified clevidipine as an alternative to SNP for perioperative hypertension in cardiac surgery. Nicardipine was considered as well, but was not chosen as a substitute due to lack of strong evidence and comparative data with SNP.
  
  
  RESULTS
  Clevidipine was implemented successfully in our cardiac surgery patients and will result in a net cost avoidance of approximately $300,000 in 2016. This is thought to be driven largely by the difference in acquisition cost between clevidipine and SNP. The operating room in our institution no longer keeps SNP stocked in anesthesia trays as a result of the success of our interchange. No requests have been made to return to the SNP standard.
  
  
  CONCLUSIONS
  Through effective communication and multidisciplinary collaboration, our institution was able to develop an evidence-based and effective therapeutic interchange program for SNP.
