Safe Use of Single Dose/Single Use Medications to Prevent Healthcare-associated Infections
•Under certain conditions, it is permissible to repackage single-dose vials or single use vials (collectively referred to
in this memorandum as “SDVs”) into smaller doses, each intended for a single patient: The United States Pharmacopeia (USP)
has established standards for compounding which, to the extent such practices are also subject to regulation by the Food and
Drug Administration (FDA), may also be recognized and enforced under §§501 and 502 of the Federal Food, Drug and Cosmetics
Act (FDCA). These USP compounding standards include USP General Chapter 797, Pharmaceutical Compounding - Sterile Preparations
(“USP <797>”). Under USP <797>, healthcare facilities may repackage SDVs into smaller doses, each intended for use with one
patient. Among other things, these standards currently require that:
•The facility doing the repackaging must use qualified, trained personnel to do so, under International Organization for Standardization
(ISO) Class 5 air quality conditions within an ISO Class 7 buffer area. All entries into a SDV for purposes of repackaging
under these conditions must be completed within 6 hours of the initial needle puncture.
•All repackaged doses prepared under these conditions must be assigned and labeled with a beyond use date (BUD), based on
an appropriate determination of contamination risk level in accordance with USP <797>, by the licensed healthcare professional
supervising the repackaging process.
•Administering drugs from one SDV to multiple patients without adhering to USP <797> standards is not acceptable under CMS
infection control regulations: Medications in SDVs typically lack antimicrobial preservatives. According to the Centers
for Disease Control and Prevention (CDC), ongoing outbreaks provide evidence that medications from SDVs can become contaminated
and serve as a source of infection when they are used inappropriately.
•Deficiency Citation Policy: Healthcare facilities that do not adhere to USP <797> standards but reuse SDVs for multiple patients
must be cited for deficiencies under the applicable infection control standards for each type of provider/supplier. On the
other hand, healthcare facilities that utilize appropriately stored medications, derived from repackaged SDVs and prepared
in accordance with USP <797> must not be cited solely on the basis of this practice.
