like? What are the costs of standardizing? What level of evidence is needed
to introduce a best practice? One may be willing to adopt what looks to be
an improvement, even without the highest bar of evidence, if the cost is
low. However, if there is a high cost, then more evidence is required.
The benefits of standardization have been well presented. The main
risk may relate to the energy required to implement a standardized drug
label. That is, those efforts might detract from other efforts that are needed
to address the problems of low adherence and medication errors.
The Agency for Healthcare Research and Quality (AHRQ) is engaged
in a number of activities related to drug labeling and patient understand-
ing. For example, AHRQ has been working with the National Council for
Prescription Drug Programs on a program related to standardization in
ePrescribing.1 It is important to examine whether the standardized message
the pharmacist receives from the physician is actually a good message to
put on the pill label.
AHRQ has also been working on the opportunities for counseling
about medications. There are opportunities in inpatient care for discharge
education and counseling. A number of projects have been funded in this
area, and some of them have developed pictorial graphic pill calendars for
patients that display the schedule for their medications. Another project
has developed a pill card that is currently being tested. When a patient
fills a new prescription at the pharmacy, he or she will receive a pill card
with a list of all the medications that have been filled at that pharmacy
and instructions for how to take them. The pill card uses various icons
such as the sun to indicate morning and the moon to indicate night. The
project has also developed a health literacy assessment guide. The guide
is used by pharmacies to determine how well they are doing in commu-
nicating with their patients and addressing variable health literacy.
AHRQ is also involved in a project called “Questions Are the Answer.”
Research has shown that patients who leave a provider’s office with ques-
tions are more likely to have a patient safety event. Thus, a website that
aids patients in constructing a list of pertinent questions to ask their doc-
tors has been developed for patients to use before their appointments. The
project has also developed a musical public service announcement. And
AHRQ is developing a health literacy assessment of patients’ experiences,
including a question about how easy it was to understand the medication
instructions given by the physician.
1 ePrescribing is defined as “the transmission, using electronic media, of prescription or
prescription-related information, between a prescriber, dispenser, PBM, or health plan, ei-
ther directly or through an intermediary, including an ePrescribing network. E-prescribing
includes, but is not limited to, two-way transmissions between the point of care and the
dispenser” (Federal Register, 2005).

Brach concluded that there will always be some people who do not
understand instructions, no matter how carefully the label is written.
Therefore, drug labeling needs to be part of an overall strategy to improve
medication adherence and reduce medication errors.

Food and drug Administration
The Food and Drug Administration (FDA) supports evidence-based
standardization as a baseline for information accessibility as demonstrated
through FDA regulations that require nutrition-facts panels on foods
and drug-facts labels for over-the-counter products. Consistently placed
information assists the targeted audience in finding information, read the
information, and, it is hoped, apply the information. Standardization may
be particularly important for populations with limited literacy.
The majority of the findings in the ACP Foundation white paper are
well supported by the literature. A major strength of the white paper lies
in its proposal for standardization of dosing instructions to the degree to
which the implementation of those standards is evidence based. The ques-
tion is, What specific standard for dosing information will improve under-
standing and appropriate use of prescription medications, especially for
those with lower literacy and health literacy skills? Unfortunately, there is
a risk that the desire to rapidly achieve standardization could undermine
appropriate research.
For many years, FDA has deferred to state regulations and state
boards of pharmacy in determining what information should appear on
prescription drug container labels. In fact, there are many who believe
that prescription medications are exempted from the Federal Food, Drug
and Cosmetic Act requirements for providing adequate directions for use.
For the FDA to establish a requirement or set a standard concerning drug
labels would be viewed as interfering with the practice of pharmacy. Once
a drug is approved for marketing, prescribers are free to prescribe it con-
sistent with their clinical judgment. The FDA does not have the authority
to dictate to prescribers how they should write their prescriptions.
Information surrounding the container label (i.e., patient package
inserts) is regulated by the FDA. In response to the Institute of Medicine
(IOM) report on the future of drug safety (IOM, 2007) and with informa-
tion obtained from public meetings, the FDA Center for Drug Evaluation
and Research is putting together a strategic risk communication plan that
will include an examination of all the tools currently used by FDA for
communicating drug information. Furthermore, even though consumer
medication information sheets are not regulated by the FDA, Congress
OCR for page 19
stAndARdizing MediCAtion lABels
has mandated that FDA assess the program’s success and has defined suc-
cess as 95 percent of patients in the year 2006 who received new prescrip-
tions also having received useful information with their prescriptions.
FDA has also recently established a Risk Communication Advi-
sory Committee that will provide a forum for discussion of issues and
approaches to improving how FDA is communicating with its targeted
audiences—both patients and health care providers. The committee will
not be addressing specific drug issues or specific device issues but rather
will focus on broader issues, such as health literacy and how to appro-
priately communicate both the risks and benefits of the products FDA
regulates from foods through biologics, drugs, and medical devices.
The FDA agrees that standardization is a good idea and that imple-
mentation should be evidence based. Implementation could occur through
the National Association of Boards of Pharmacy (NABP) and the state
boards of pharmacy. The NABP has, for example, a set of model laws that
could incorporate standards for prescription container labels. Finally, the
FDA does not perceive that existing federal regulations would interfere
with implementing standardization.

department of veterans Affairs
As a comprehensive health care system, the Department of Veterans
Affairs (VA) may face challenges that differ slightly from those encoun-
tered in the private sector. The VA serves approximately 5 million veteran
patients and dispenses approximately 120 million prescriptions a year. It
serves an aging population, the average age of which is approximately 65
years old. Understanding the instructions through the health care process
is challenging.
The VA has ePrescribing, it has treatment guidelines, and it will be
developing more robust decision support systems. Currently the VA is
examining standardization of nomenclature as part of its ePrescribing, a
result of an initiative that merged the prescription portion of VA’s elec-
tronic medical record information system with that of the Department of
Defense. Phase II of the merger will examine laboratory information. The
VA is also building a personal health record that not only provides infor-
mation about medications, but will also provide such things as reminders
to patients of appointments and upcoming laboratory work. Additionally,
if individual patients agree, community providers can include information
in the records and patients can list over-the-counter items they purchase.
The VA system integrates the prescribing and filling of prescriptions
with an examination of patient understanding and adherence. An impor-

tant component of proper prescription use is communication from the
provider to the pharmacist about the purpose of the prescribed medica-
tion. There may also be future opportunities to provide the pharmacist
with additional information that will allow him or her to assess, for
example, whether a laboratory goal has been met or if there have been
risks occurring with certain medications. Pharmacists in the VA work with
medical teams, often in clinic settings, where they review the appropriate-
ness of the medication on a medical record, counsel patients, and check
to see if patients understand instructions. One approach includes shared
appointments, where patients meet with several providers (e.g., physi-
cian, nurse, nutritionist, pharmacist) at the same time who communicate
with the patient about his or her health and treatment.
The VA shares the commitment to improve health literacy and sup-
ports the need for medication label changes but believes such changes
should be just one part of a larger approach that must include accessible,
verbal communication.
DISCuSSION
An audience member asked if, without considering whether it is the
correct thing to do, it would it be possible to write federal legislation
or regulations that would mandate standardized drug labeling. Brach
stated that the Medicare Prescription Drug, Improvement and Modern-
ization Act of 2003 actually mandates the adoption of standards for inter-
operability for ePrescribing so that from the prescriber to the pharmacist,
there will be a standard. One might say, therefore, that standardization
has a legislative basis.
Ostrove responded that it is probably possible, but one then must ask
whether it would be the most appropriate approach. Given the historical
deferment to the states, the practicality of federal regulation is probably
fairly limited. There would most likely be objections about interference
with the practice of pharmacy and the practice of medicine.
Panelists were asked, if everyone seems to agree that standardizing
the drug label is a good idea, how can this be accomplished without an
accompanying policy change? How will these standards be enforced?
For example, current evidence shows that despite extremely detailed
guidance on the development of FDA medication guides, this guidance
is not followed. Should standards be developed and merely circulated
with the hope that they will be adopted? Should there be a model practice
act developed that is similar to the new California law? While some best
practices have been identified, there is no real incentive for their adop-
tion. One can travel through each of the 50 states in the United States and
know what a stop sign looks like, but there is no consistency about what
OCR for page 19
stAndARdizing MediCAtion lABels
a “no food” symbol on a prescription bottle looks like. What will cause
the situation to change?
Ostrove responded that these are issues of implementation and raise
the overall question of whether the introduction of standards should be
a grassroots approach or whether it should be through legislation and
regulation. Even if one were to implement regulations, it does not mean
that practice will conform, as seen from research that shows mandated
medication guides are not distributed. Brach responded that from the
perspective of a non-regulatory federal agency, there are options short of
regulation, such as working with relevant associations and organizations.
If there is sufficient evidence to support standardization, then one could
bring relevant groups together to develop an implementation strategy.
Such groups might include the Department of Health and Human Ser-
vices, private-sector partners from relevant associations (e.g., from phar-
macy and medicine), and the IOM Roundtable on Health Literacy.
The panel was then asked whether the expanding use of electronic
medical records presents any additional regulatory or legislative possibili-
ties or issues. Brach responded that, to her knowledge, there are no pro-
hibitions to such legislation or regulation. Currently there are a number
of systems operating. The Department of Health and Human Services is
engaged in trying to reach a consensus about interoperability among the
many vendors of the systems that do exist, but it is not pursuing regula-
tion in this area. Torrise agreed that there is probably nothing that would
prevent such regulation, but there are disincentives.
Panelists were then asked if each would state who should take lead-
ership on moving forward on the issue of drug label standardization.
Torrise stated that since the VA is, in effect, its own state board of phar-
macy, it can write the necessary policies for its system. Furthermore, the
VA will be closely examining the issue of standardization to determine
how to move forward in this area. Brach suggested that the implementa-
tion issues are beyond the purview of one federal agency and, instead,
require the cooperation of all those involved. From the AHRQ perspec-
tive, Brach stated, one needs to determine how drug label standardization
would be integrated into the overall strategies of improving other pieces
of the system, such as patient counseling, since merely standardizing drug
labeling would not fix the problems of medication safety and adherence.
Ostrove agreed with Brach and further pointed out that there is as yet
no information on the impact of such standardization on patient adher-
ence. Until that is available, the best that can be done is to develop a
theoretical marketing plan for the idea. Groups that could be instrumental
in moving forward with this include the IOM, working very closely with
the pharmacy industry and the NABP.
