RAA is managed by Somnia. Q: As a practicing consultant pharmacist to ambulatory surgery centers, I am often asked about the beyond use dating of medications drawn into syringes. Since most ASCs do not have an isolator or glove box for this procedure, I advocate following USP , and consider those pre-drawn syringes an immediate-use compounded sterile preparation, and suggest a one-hour beyond use dating. Is this too stringent? Does USP apply in these situations if they are not IV admixtures but are, for example, injectable local anesthetics which are not given intravenously? Clifford Gevirtz: Yes, I think you the consulting pharmacist are going a bit far in your interpretation. To quote from the USP guideline www. However, if the expiration date of the vial is sooner than 28 days, then it expires on that date. Good practice is note the date first entered on the label.

Ok, but not good enough says the Joint Commission. To be in compliance with MM. Just labeling the multi-dose vial with the date opened will not meet the intent of this requirement. The label should look something like this. Medications in single use vials are preferred over multi-dose vials but avoid the urge to use single use vials for multiple patient use.
Single-use vials should only be used for one patient and one procedure, with new, clean needles and syringes. All vials and syringes should be wasted and discarded at the end of the procedure. Do not combine leftover contents for later use. Consider the disposal of the remaining medication as a safety step, rather than a waste of resources. Always use a clean needle and syringe with each use of a multi-dose vial. Discard any unmarked vials, opened single-use vials, or multi-dose vials that have not been labeled appropriately.

Multi-Dose Vials: Multiple Compliance Targets
There continues to be significant confusion regarding the storage period for multi-dose vials subsequent to their initial puncture. Many organizations have been cited by The Joint Commission, state boards of pharmacy, and departments of health for not discarding multi-dose vials after 28 days. Filed under: FAQ.
Results: Over an 8-month period, consecutive vials were cultured for aerobic and anaerobic bacteria at the 3-month expiration date after.
Isolation of HIV-1 from experimentally contaminated multidose local anaesthetic vials. To investigate the hypothesis that HIV can be transmitted via contamination of multidose vials of local anaesthetic solution through reuse of needles and syringes. Laboratory study. In some settings, HIV could be isolated four hours after exposure. When inadvertently contaminated with HIV, multidose solutions represent a potential source of transmissible virus. Using compounded multidose vials cMDV is a common practice in the laboratory animal setting, where medications often are diluted to provide appropriate doses to rodents.
However, bacterial contamination of MDV has been well established in both the human and veterinary medical literature. The stoppers of the cMDV were not cleaned with alcohol, and all were punctured twice daily for 28 d. The sterility of the diluted carprofen was evaluated by assessing bacterial growth on days 0, 7, 14, 21, and 28 and by testing for bacterial endotoxin on days 0 and We used liquid chromatography-tandem mass spectrometry to assess the stability of 2 cMDV, with each cMDV being divided into the 2 storage-temperature subsets for days 0, 7, 14, 21, and Neither bacterial contamination nor endotoxin was detected, and drug stability was stable over the 28 d.
We suggest that with pragmatic techniques, such as secondary containment and consistent use of new needles, the contents of cMDV can remain sterile and stable for 28 d.

A multi-dose vial is a vial of liquid medication intended for parenteral administration injection or infusion that contains more than one dose of medication. Multi-dose vials are labeled as such by the manufacturer and typically contain an antimicrobial preservative to help prevent the growth of bacteria. The preservative has no effect on viruses and does not protect against contamination when healthcare personnel fail to follow safe injection practices.
Multi-dose vials should be dedicated to a single patient whenever possible. If multi-dose vials must be used for more than one patient, they should only be kept and accessed in a dedicated clean medication preparation area e.

Multidose injection vials MDVs are prone to bacterial contamination, and their use has been reported to be a potential source of infections. The aim of this study was to evaluate the knowledge and common practises of nursing staff regarding the use of MDVs and its microbial contamination rate. A pilot study was conducted in a super-specialty hospital from June to December Information about knowledge and common practises of nursing staff posted in various Intensive Care Units ICUs with respect to the usage of single and MDVs, respectively, was obtained and assessed.
About 40 in-use multidose injection vials containing some remnants were collected from different ICUs. The broth was visually examined every day and subcultured onto blood, chocolate, and Sabouraud Dextrose agar plates on alternate days within 10 days or any time that the appearance seemed turbid. The microbial isolates thus obtained were identified using standard guidelines and recorded.
The study group members had sufficient knowledge about various aspects of handling single and MDVs, respectively, such as hand hygiene, disinfection, checking of vial labels, and expiry date. The use of MDVs is associated with the risk of contamination and nosocomial outbreaks of life-threatening bloodstream infections. Healthcare professionals must strictly adhere to basic infection control practises as per standard guidelines to minimize the incidence of hospital-acquired infections. These vials are labeled as such by the manufacturer and typically contain antimicrobial preservatives such as benzyl alcohol, benzethonium chloride, methylparaben, propylparaben, and metabisulphite to prevent bacterial growth.

As an example, a multi-dose vial of lidocaine that was used to create a skin wheal prior to starting an IV would be good for 28 days after first.
There has been much more attention recently on multidose vials, particularly the expiration date of these vials, especially from regulatory organizations such as CMS and The Joint Commission. The following is an email interview with Susan A. Q: Why have multi-dose vials been an issue in the past, and why do they continue to be problematic for some facilities? A: Multi-dose vials have been and continue to be a confusion for healthcare personnel HCP because they either are not fully aware of or do not follow basic infection control practices as they pertain to vials.
The term multidose seems to be confusing because it is seen by some HCP as being able to be used more than once. Q: Where do facilities fall short with compliance when it comes to best-practices for multidose vials? Q: How long should you keep multidose vials? How often does the day rule apply? Is that commonplace for most vials at this point? The paper indicates it is an unresolved issue, why is that?

Background: US Pharmacopeia USP Chapter states that single-use vials may be used within 6 hours of initial puncture if maintained in an International Organization for Standardization 5 environment. The 6-hour standard is based on the microbial growth observed in various growth media under conditions specified in USP Chapter In these studies, the PhaSeal system was tested using growth media under simulated conditions.
Extending the beyond-use date BUD of medications could reduce expenditures for medications, and help pharmacists cope with shortages of critical medications. Objective: The purpose of this study was to confirm these results in actual practice, using an antineoplastic agent as the test solution. Methods: In this prospective, observational study, fluorouracil aliquots were transferred to tryptic soy broth culture medium in intravenous bags over a 2-week period, using the PhaSeal system.
Twelve aliquots and 96 bags were used. Results: No microbial growth was observed throughout the day period. The use of closed-system transfer devices CSTDs for compounding hazardous medications has become an accepted standard of practice to minimize environmental exposure to these agents. In addition, using a CSTD to preserve the sterility of vials of parenteral medication may assist pharmacists in managing shortages of such drugs.
If using such a device ensures the sterility of these drugs so that all the contents of the vial can be used without harming the patient, then overall drug waste could be reduced substantially. Use of a CSTD to extend the BUD has been suggested to minimize the impact of drug shortages, as well as medication waste, and can result in significant cost-savings.
