Cost savings realized by use of the PhaSeal(®) closed-system transfer device for preparation of antineoplastic agents.

PURPOSE

Medication cost is a major factor associated with increasing health care costs in the United States. Expenditures for prescription drugs in 2013 are estimated to be $283.7 billion. Closed system transfer devices are widely used for preparation of hazardous drugs. Reports indicate the Phaseal(®) closed system transfer device maintains sterility in vials for 7 days, suggesting the unused portion of single-use vials could be salvaged. This study was done to determine whether using a closed system transfer device to extend the beyond-use date of single-use vials of antineoplastic medications would result in a measurable cost saving.

METHODS

A list of 25 drugs available in single-use vials, with a chemical stability of at least 48 hours, was compiled. Use of these agents was recorded during a 50-day period in April through June 2012. Use from a total of 296 vials of 21 antineoplastic agents was recorded. After allowing for the initial use of each vial, the mean potential percentage of drug waste was calculated to be 57.03%.

RESULTS

Actual savings during the study period was $96,348.70. The pharmacy avoided nearly half of the potential waste and saved a mean of 29% of each vial. The cost-saving during the study period represents a $703,047.67 annual saving; which more than offsets the $106,556.55 the pharmacy spent for the Phaseal(®) system in 2012.

CONCLUSION

In addition to being a protective measure to reduce exposure to hazardous agents, use of the Phaseal(®) system results in a reduction in drug waste, and a noticeable cost saving for antineoplastic agents.
