Academic Medical Center

  • Vial2Bag® Device Study
  •  Single center, retrospective analysis performed from June 2017 - July 2018
This study was conducted using a device that is no longer on the market. West now offers the Vial2Bag Advanced™ 20mm Admixture Device as its transfer device.
  • Hospital Profile
  •  Annual Sterile Compounding: 150,000 patient-specific; 300,000 anticipatory


Extrapolated cost avoidance* realized from 250,000+ doses dispensed following Vial2Bag® device implementation

  • Reduce pharmacy labor, equipment and material cost versus Locally Compounded Sterile Product (LCSP)2,5-9**
  • Reduce risk of contamination and extend stability compared to LCSP3,4
  • Reduce expensive ready-to-use products
  • Reduce unnecessary compounding labor and materials2
  • Allow for unused drugs to be returned to inventory2****

Annual units of LCSP moved from pharmacy to point-of-care through Vial2Bag® device dispensing

  • Reduce time to first dose through preparation at point-of-care as compared to LCSP
  • Utilize an Automated Dispensing System (ADS) to potentially reduce medication errors related to preparation and administration
  • Increase medications stocked in ADS
  • Flexible solution for managing drug shortages
  • Universal compatibility with all manufacturers’ 50, 100, and 250mL IV bags and 20mm vials***

Optimizing drug product utilization can improve workflow & minimize cost

Supply Disruptions

experience supply disruptions from their hospital’s manufacturer or outsourced facilities10

Impact to Patient Care

experienced a patient safety event due to this supply disruption10

Resource Constraints

agreed that outsourcing IV admixtures was cost-effective10

* Extrapolated yearly cost avoidance was measured by multiplying the number of documented yearly administrations by the difference in respective LCSP or RTU costs from V2B system costs.
** LCSP labor and equipment costs were based on previous time study data that evaluated the costs of preparing small volume injectables (SVI)
*** ISO 8536-4 standard IV spike
**** A drug is considered unused if vial remains unpunctured and within manufacturer's expiration date

Vial2Bag® Admixture Device and Vial2Bag Advanced® Admixture Device are separate products; West’s Vial2Bag Advanced® Admixture Device replaced the Vial2Bag® Admixture Device in commerce.
