In a decades-old debate, the United States Pharmacopeia (USP) is expected to take action that could prevent manufacturers from printing U.S. Food and Drug Administration-required and approved dosage and other identifying information on the caps of injectable drugs. This information serves as a final warning and safety checkpoint before a drug is dispensed and injected.
On April 15, 2010, the Consortium for the Advancement of Patient Safety (CAPS) submitted results of a three-part report, including a human factors engineering analysis, on the relationship between patient safety and printed messages on ferrule and cap overseals used to secure injectable drug vials. CAPS commissioned this study to provide independent, empirical data to the USP in response to USP’s proposed revision of USP General Chapter, Injections, Labeling on Ferrules and Cap Overseals. CAPS was formed to educate and promote awareness of the benefits of printing on drug packaging, specifically secondary closures, to mitigate medication errors and improve patient safety.
“USP appreciates that CAPS provided data in support of its comments on the proposed standard,” says Matthew Heyman, VP, external affairs and strategic integration, USP. “The study, along with other comments on the proposed standard, was presented to the Nomenclature Expert Committee for its consideration. That Committee’s decision and other relevant information will be posted shortly on www.usp.org.”
The USP proposal, expected to become effective May 2011, would limit printing and other types of messaging on the top of the drug vial, such as ferrules and cap overseals. The USP published its most recent revision in the Pharmacopeial Forum Vol. 36 (1), around February 2010. Because of the absence of data on this issue, a member of the Food and Drug Administration recommended that CAPS conduct a HFE study during a meeting CAPS had with the agency last year.
CAPS members believe that limiting information to warnings of imminent life-threatening situations ignores the potential impact of medication errors. Patient safety includes more than just imminent life-threatening events. The affect of other medication errors should be taken into consideration.
The proposed limitations may interfere with anti-counterfeiting strategies applied to ferrules and cap overseals. A plain cap is easier for counterfeiters to duplicate. Product identification efforts are often linked to anti-counterfeiting efforts, so even product names serve a purpose not related to advertising or marketing. Counterfeiting is a threat to public health and should be considered in any patient safety program.
“We are hoping that the independent comprehensive study, contracted by CAPS, will correct some of the misperceptions which seem to be the premise for the proposed restrictive language in USP General Chapter 1, Injections, section on Labeling on Ferrules and Cap Overseals,” says Fran DeGrazio, VP, marketing and strategic business development, West Pharmaceutical Services Inc. “The approach that CAPS has taken to utilize an independent scientific and fact-based study to understand this issue is logical. Our hope is that this information will be strongly considered by the USP in their decision concerning the revised wording of this section of Chapter 1. I believe we are all interested in ensuring that results from our decisions promote and support patient safety.”
Printing on caps can be changed easily to support evolving patient safety initiatives and does not impact the primary packaging. The CAPS organization believes that the drug company is the most appropriate to determine what information to present on ferrules and cap overseals.
“The CAPS empirical study was completed in March 2010,” says Frederick J. Balboni, Jr., executive director, CAPS. “For the first time, we are able to cite factual, unbiased data strongly supporting and validating our hypothesis that the revision has the potential to pose a serious threat to patient safety.”
In three parts, the data states that there was no finding of medication errors associated with this type of printing; that the majority of participants felt the messages were important and beneficial in preventing medication errors, and consequently were in favor of less restrictive language; and the evaluation associated with understanding how the presence or absence of information is noticed by health care providers indicated that “less is not necessarily more,” meaning that limiting the messages to less critical information does not make the critical information more visible.
On May 25, 2010, CAPS presented this data on this issue at a meeting of the USP’s Nomenclature Expert Committee. It is the organization’s hope the unbiased data garnered in this study will assist the Nomenclature Committee in developing a viable standard acceptable to both USP and industry with the primary objective of insuring patient safety.
