NCVHS' Recommendations for E-Prescribing Standards
September 2, 2004
The Honorable Tommy G. Thompson
Secretary
US Department of Health and Human Services
200 Independence Avenue, SW
Washington, DC 20201
Dear Secretary Thompson:
The National Committee on Vital and Health Statistics (NCVHS) has
been called upon by the Medicare Prescription Drug, Improvement,
and Modernization Act of 2003 (MMA) to develop recommendations for
uniform standards to enable electronic prescribing (e-prescribing)
in ambulatory care. E-prescribing should enable significant improvements
in patient safety, quality of care, and cost effectiveness. Standards
for e-prescribing must not only meet the requirements of MMA but
must also be compatible with all other standards that are becoming
part of the National Health Information Infrastructure (NHII). This
includes standards developed under the Health Insurance Portability
and Accountability Act of 1996 (HIPAA) and the Consolidated Health
Informatics Initiative (CHI).
In order to expedite the development, implementation, and pilot
testing of e-prescribing standards by the Department of Health and
Human Services (HHS), NCVHS is providing this first set of recommendations.
Additional recommendations will be sent in March 2005.
Current Prescribing Environment
Today, prescribers (physicians and others who write prescriptions)
make their drug-prescribing decisions using whatever medical, medication,
and eligibility information is known or available to them. Typically
they give a handwritten prescription to the patient or fax it to
the dispenser (patient's pharmacy of choice). At the dispenser,
tasks are somewhat more automated. Through internal and external
electronic claims, eligibility, and benefits verification processes,
the dispensing pharmacist may identify contraindications, lower
cost alternatives, or the need for prior authorization. At any of
the steps in the process, the dispenser may need to contact the
prescriber by phone for clarification or approval of changes. Dispensers
also must frequently call the prescriber to obtain approval for
refills or renewals where they are not specified on the prescription
or when they have run out. According to some estimates, almost 30
percent of the 3 billion prescriptions written annually[1] require dispenser calls.[2]
This equals 900 million prescription-related telephone calls annually.
Many reports have identified that the current prescribing process
is prone to errors. Prescribers may not have access to the latest
drug knowledge. They often do not have a complete or accurate medication
list or even medical history for their patient, and, as a result,
they can miss potential contraindications or duplicate therapies.
Dispensers often have difficulty reading handwritten prescriptions
and frequently have little or no information about the patient's
condition for which the prescription is written. Contacting the
prescriber by phone to clarify what is ordered and to make changes
often results in delays for the patient, and it is time-consuming
for both the prescriber and the dispenser. There are disconnects
between the prescriber and patient in the medication process, with
little or no feedback to the prescriber on whether a prescription
was filled or what generic substitutions were made. Every year,
more than 8 million Americans experience outpatient adverse drug
events (ADEs). Analysis shows that e-prescribing systems can avoid
more than 2 million ADEs annually, of which 130,000 are life-threatening.[3]
Current E-Prescribing Capabilities
E-prescribing has the capability of addressing many of these issues.
The eHealth Initiative provided a helpful framework to conceptualize
e-prescribing systems.[4] It describes
graduated levels of functionality, producing differing sets of benefits.
Today, various levels of e-prescribing systems are being implemented.[5]
However, the lack of e-prescribing standards has forced the industry
to use workarounds to accomplish many aspects of e-prescribing.
The following describes levels of e-prescribing systems derived
from the eHealth Initiative framework and the extent of their use
today:
- Basic Reference Information. E-prescribing reference
tools provide basic drug information, dosing calculation, and
formulary information. Recent estimates suggest that about 15
percent to 17 percent of prescribers use such systems.[6]
These systems may prevent errors by making appropriate reference
information readily available. While there are several formulary
reference products on the market, their content and format are
not standardized. Some community projects have attempted to map
the various formulary products to one another.
- Standalone Prescription Writers. These e-prescribing
applications produce a legible prescription and include dosage
information. They do not provide access to any patient-specific
information or connectivity with dispensers.
- Integrated E-Prescribing Systems. These systems are more
sophisticated in several ways: Some products combine patient demographics,
allergy, formulary, and plan information. Others can assist in
medication management. Still others may connect the prescriber
with the dispenser to transmit a prescription. To obtain patient
demographics and allergy information, the products depend on either
linking to a practice management system (PMS) or the re-entry
of data. To receive formulary and plan information, prescribers
may connect with third-party information exchange networks that
integrate medication history and/or eligibility information from
pharmacy benefits managers (PBMs). To route e-prescriptions to
dispensers, prescribers often use electronic fax, which requires
re-entry of the prescription information by the dispenser. Some
prescribers with electronic data interchange (EDI) capability
are routing prescriptions through a switching network. The National
Council for Prescription Drug Programs (NCPDP) has developed a
standard (SCRIPT) for communications between prescribers and dispensers.
NCPDP estimates that 75 percent of pharmacies have the capability
to receive messages using the SCRIPT Standard. However, fewer
than 3 percent of all prescriptions are written by prescribers
using an integrated e-prescribing system.[7]
- Electronic Health Record Systems with E-Prescribing.
Still further enhancements to quality and patient safety can be
achieved by integrating the medication order into the overall
process of medical care delivery. This level of e-prescribing
requires an electronic health record (EHR) that integrates data
from multiple sources, is used at the point of care, and provides
evidence-based clinical decision support. EHR systems are deployed
at an estimated 14 to 28 percent of practices.[8]
It is unknown how many of these are comprehensive EHR systems
and how many utilize standard industry protocols.
Standards Evaluation Process
Charged with the task of recommending standards for e-prescribing
to promote patient safety and quality health care, NCVHS scheduled
testimony in 2004 to learn:
- Which standards are needed to support e-prescribing
- How MMA requirements are supported or not supported by current
standards (i.e., standards gaps and limitations)
- What related issues exist that may affect the implementation
or acceptance of e-prescribing
After this information was gathered, NCVHS then reviewed the standards
gaps and limitations with the standards developers. This dialogue
helped NCVHS determine what standards have adequate industry acceptance
and what actions are necessary to address gaps and limitations in
standards for them to be available for the MMA demonstration projects
beginning January 2006. See Appendix A for the NCVHS work plan.
The MMA provides that pilot testing of standards is not required
where there already is adequate industry experience with the standards.
At the July 21, 2004, Health Information Technology Summit, HHS
announced its intent to accelerate the implementation of e-prescribing
by proposing an initial set of well-established standards for implementation
by January 2006, when the Medicare Part D benefit begins. Standards
appropriate for inclusion in this initial set are identified in
the NCVHS recommendations below as "foundation standards."
Stakeholder Testimony
NCVHS received testimony from all stakeholder groups identified
in the MMA (i.e., standards setting organizations, practicing physicians,
hospitals, pharmacies, practicing pharmacists, pharmacy benefit
managers, state boards of pharmacy, state boards of medicine, experts
on e-prescribing, other appropriate Federal agencies). In addition,
testimony was heard from e-prescribing networks, demonstration projects,
software developers, and consumer advocacy organizations. (See Appendix
B for list of testifiers.) In over 11 days of deliberations from
March to September 2004, NCVHS heard from 65 testifiers and other
industry experts.
Guiding Principles for Selecting Standards
In making its recommendations, NCVHS utilized the guiding principles
and requirements identified in the MMA for selecting e-prescribing
standards[9]:
- Improve patient safety
- Improve quality of care
- Improve efficiency (including cost savings)
- Not present an undue administrative burden on prescribers and
dispensers
- Be compatible with other standards
- Permit electronic exchange of drug labeling and drug listing
information maintained by the Food and Drug Administration (FDA)
and the National Library of Medicine (NLM)
- Include quality assurance measures and systems
- Permit patient designation of dispensing pharmacy
- Comply with HIPAA Privacy regulations
- Support interactive and real-time transactions
In addition, NCVHS believes the standards should be vendor neutral
and technology independent, preferably be developed by standards
development organizations accredited by the American National Standards
Institute (ANSI), and have suitable indications of market acceptance.
Types of Standards and Important Related Issues
There are three types of e-prescribing standards that NCVHS identified
and evaluated as being necessary to support e-prescribing. They
are: message format standards that provide communication
protocols and data content requirements (including those to support
medication decision making), terminologies to ensure data
comparability and interoperability, and identifiers for all
relevant entities within the e-prescribing process.
NCVHS notes there are privacy considerations uniquely related to
e-prescribing, which will be investigated in subsequent hearings
and reflected in the March 2005 recommendations.
NCVHS further observed that deployment of e-prescribing may involve
policy or workflow issues that are outside the scope of standards
but are important related issues.
Observations and Recommended Actions
NCVHS observes that the US healthcare system has made considerable
progress in developing pragmatic solutions for e-prescribing. These
solutions provide an excellent foundation to build upon. The status
of each e-prescribing standard evaluated is described in detail
in the working document in Appendix C.
Following is a list of observations and associated recommended
actions. The observations describe the purpose and extent of industry
experience regarding a standard or issue. The recommended actions
under each observation recognize first any foundation standards,
then the actions to address additions, development, and pilot testing
necessary to meet the MMA requirements. While foundation standards
do not in themselves need to be pilot tested, they do need to be
tested with the expanded functionality required by MMA. The observations
and recommended actions are grouped as follows: general overarching
items, message format standards, terminologies, identifiers, and
important related issues.
Observation 1 (General Standards Compatibility): Many testifiers
emphasized to NCVHS how important it is that e-prescribing standards
be compatible with all HIPAA standards, CHI standards, and the clinical
data terminologies recommended by NCVHS in November 2003. This is
to avoid dual standards for Medicare Part D and all others. The
testifiers' observations are consistent with the MMA requirements
that e-prescribing standards should be compatible with HIPAA standards
and "general health information technology standards."
Recommended Action 1.1: HHS should ensure that e-prescribing
standards are not only appropriate for Medicare Part D but also
for all types of prescribers, dispensers, and public and private
sector payers.
Recommended Action 1.2: HHS should ensure that e-prescribing
standards are compatible with those adopted as HIPAA and CHI standards,
and with those recommended in November 2003 by NCVHS for clinical
data terminologies.
Observation 2 (General Standards Versioning): There are
lessons learned from HIPAA regarding both the value of standards
and the need for flexibility to respond to industry requirements
and technology changes. There are a number of approaches that could
be considered to provide the industry greater flexibility and ability
to advance, while maintaining standardization of messages and data.
For example, the CHI has set precedence for this through adopting
a version of its clinical information standards as a baseline, from
which new versions may be adopted by the industry when ready; although
this process is different from the process required for standards
adopted under HIPAA.
Recommended Action 2.1: HHS should work with the industry
in its rulemaking process to determine how best to afford flexibility
in keeping standards in pace with the industry, including standards
for HIPAA and e-prescribing. For example, HHS might consider recognizing
new versions of standards, without a separate regulation, if they
are backward compatible.
Observation 3 (Prescription Messages): The NCPDP SCRIPT
Standard provides for the exchange of new prescriptions, changes,
renewals, cancellations, and fill status notifications. Each function
has varying degrees of industry experience. The NCPDP SCRIPT new
prescription function is most widely used. The renewal function
has good industry acceptance, represents an easy transition, and
provides the most immediately apparent return on investment. The
NCPDP SCRIPT Standard cancellation and change functions are currently
underutilized.
Testimony indicated that the fill status notification function
is not used today. Testimony also revealed that there were questions
about the business value and clinical utility of the fill status
notification function, as well as possible privacy issues.
The NCPDP SCRIPT Standard allows for both free text in certain
fields and choices of codes. It is critical to standardize on common,
interoperable terminologies to provide automated decision support
required by portions of the MMA that relate to patient safety and
cost benefits. These items are specifically addressed in later recommendations.
Recommended Action 3.1: HHS should recognize as a foundation
standard the most current version of NCPDP SCRIPT for new prescriptions,
prescription renewals, cancellations, and changes between prescribers
and dispensers. The NCPDP SCRIPT Standard would include its present
code sets and various mailbox and acknowledgement functions, as
applicable.
Recommended Action 3.2: HHS should include the fill status
notification function of the NCPDP SCRIPT Standard in the 2006 pilot
tests. These pilot tests should assess the business value and clinical
utility of the fill status notification function, as well as evaluate
privacy issues and possible mitigation strategies.
Observation 4 (Coordination of Prescription Message Standards):
Health Level Seven (HL7) is commonly used to communicate medication
orders within a hospital and with clinical pharmacies within an
enterprise. Coordination of HL7 with NCPDP SCRIPT would result in
functions being more seamless across healthcare environments. This
would remove a barrier to adoption of electronic medication ordering
and prescribing. HL7 and NCPDP have already begun to map their standards
that support common functions.
Recommended Action 4.1: HHS should financially support the
acceleration of coordination activities between HL7 and NCPDP for
electronic medication ordering and prescribing. HHS should also
support ongoing maintenance of the HL7 and NCPDP SCRIPT coordination.
Recommended Action 4.2: HHS should recognize the exchange
of new prescriptions, renewals, cancellations, changes, and fill
status notification within the same enterprise[10]
as outside the scope of MMA e-prescribing standard specifications.
Recommended Action 4.3: HHS should require that any prescriber
that uses an HL7 message within an enterprise convert it to NCPDP
SCRIPT if the message is being transmitted to a dispenser outside
of the enterprise. HHS also should require that any retail pharmacy
within an enterprise be able to receive prescription transmittals
via NCPDP SCRIPT from outside the enterprise.
Observation 5 (Formulary Messages): Formulary and benefit
coverage information, including information on the availability
of lower cost, therapeutically appropriate alternative drugs (if
any), from payers/PBMs to prescribers currently is communicated
with proprietary messages. RxHub[11]
has communicated its intent to submit its proprietary Formulary
and Benefit Information File Transfer protocol to NCPDP to establish
industry consensus and ensure the protections for the industry afforded
by becoming an ANSI-accredited standard. Development of an ANSI-accredited
standard appears to be possible in an accelerated timeframe. This
process will accommodate any specific requirements affecting the
implementation of Medicare's new Part D prescription drug program.
Recommended Action 5.1: HHS should actively participate
in and support the rapid development of an NCPDP standard for formulary
and benefit information file transfer, using the RxHub protocol
as a basis.
Recommended Action 5.2: NCVHS will closely monitor the progress
of NCPDP's developing a standard for a formulary and benefit information
file transfer protocol, and provide advice to the Secretary in time
for adoption as a foundation standard and/or readiness for the 2006
pilot tests.
Observation 6 (Eligibility and Benefits Messages): Eligibility
inquiry and response are HIPAA transactions, and standards have
been adopted for their use in retail pharmacy and other sectors.
The HIPAA standard for eligibility communications between retail
pharmacy dispensers and payers/PBMs is the NCPDP Telecommunication
Standard.[12] The HIPAA standard
for eligibility and benefits communications between dentists, professionals,
institutions, and health plans is the Accredited Standards Committee
(ASC) X12N 270/271.[13] There is good industry experience in using
the ASC X12N 270/271 standard for general drug benefit functions.
ASC X12 has identified workarounds for some of the gaps in ASC X12N
270/271 with respect to drug listings and step therapy. ASC X12
reports that version 4050 addresses some of these workarounds more
directly, and that version 5010 is under development and can more
tightly address industry needs for e-prescribing. Because Medicare's
Part D prescription drug program is new, specific requirements are
not known at this time and new requirements may emerge.
Recommended Action 6.1: HHS should recognize the ASC X12N
270/271 Health Care Eligibility Inquiry and Response Standard Version
004010X092A1 as a foundation standard for conducting eligibility
inquiries from prescribers to payers/PBMs.
Recommended Action 6.2: HHS should support NCPDP's efforts
to create a guidance document to map the pharmacy information on
the Medicare Part D Pharmacy ID Card to the appropriate fields on
the ASC X12N 270/271 in further support of its use in e-prescribing.
Recommended Action 6.3: HHS should work with ASC X12 to
determine if there are any requirements under MMA with respect to
how situational data elements are used in the ASC X12N 270/271,
especially concerning the quality of information needed for real-time
drug benefits. Use of these situational data elements could be addressed
in trading partner agreements. Specifications of use of situational
data elements, as well as proper usage of the functional acknowledgments,
should be included in the 2006 pilot tests.
Recommended Action 6.4: HHS should ensure that the functionality
of the ASC X12N 270/271, as adopted under HIPAA, keeps pace with
requirements for e-prescribing and that new versions to the Standard
be pilot tested.
Observation 7 (Prior Authorization Messages): Under HIPAA,
claims, eligibility, and benefits information between dispensers
and payers/PBMs are communicated using the NCPDP Telecommunication
Standard.[14] The need for prior
authorization for a drug is identified between the payer/PBM and
the dispenser through this process. The formulary and benefit file
transfer protocol being developed by NCPDP provides information
from the payer/PBM to the prescriber about the need to obtain prior
authorization of a drug. The NCPDP SCRIPT Standard may be used between
the dispenser and prescriber to communicate the prior authorization
approval for a drug. However, the request for a prior authorization
for a drug from the prescriber to the payer/PBM is now conducted
in a manual mode. This is due, in part, to the complexity of the
decision making involved in ensuring that the use of a drug considers
cost, patient safety, special handling or administration procedures,
and other pre-authorization requirements. It is estimated that 2
percent of prescriptions now require prior authorization, and that
there is a higher rate for Medicaid payers. This provides a natural
body of experience from which to draw data for study of economic
and quality of care impacts.
The ASC X12N 278[15] is a HIPAA standard that provides for prior
authorization inquiry and response in general. It provides very
limited support for prior authorization of drugs and is not widely
used.
Recommended Action 7.1: HHS should support ASC X12 in their
efforts to incorporate functionality for real-time prior authorization
messages for drugs in the ASC X12N 278 Health Care Services Review
Standard Version 004010X094A1for use between the prescriber and
payer/PBM.
Recommended Action 7.2: HHS should support standards development
organizations and other industry participants in developing prior
authorization work flow scenarios to contribute to the design of
the 2006 pilot tests.
Recommended Action 7.3: HHS should evaluate the economic
and quality of care impacts of automating prior authorization communications
between dispensers and prescribers and between payers and prescribers
in its 2006 pilot tests.
Recommended Action 7.4: HHS should ensure that the functionality
of the ASC X12N 278, as adopted under HIPAA, keeps pace with requirements
for e-prescribing and that new versions to the Standard be pilot
tested.
Observation 8 (Medication History Messages from Payer/PBM to
Prescriber): The exchange of medication history may occur at
multiple points: among prescribers, between patients and prescribers,
between payers and prescribers, and between prescribers and dispensers.
MMA indicates that medication history should be provided to prescribers
and dispensers but does not explicitly identify the source(s) or
actual intended use of the medication history.
Medication history from payers/PBMs to prescribers is currently
communicated primarily with proprietary messages. RxHub has communicated
its intent to submit its proprietary medication history message
to NCPDP to establish industry consensus and ensure the protection
for the industry afforded by becoming an ANSI-accredited standard.
Development of an ANSI-accredited standard for medication history
messages between payers/PBMs and prescribers appears to be possible
in an accelerated timeframe.
The following recommended actions address only exchange
of medication history from payers/PBMs to prescribers. NCVHS plans
to address other medication history communications in its March
2005 recommendations.
Recommended Action 8.1: HHS should actively participate
in and support rapid development of an NCPDP standard for a medication
history message for communication from a payer/PBM to a prescriber,
using the RxHub protocol as a basis.
Recommended Action 8.2: NCVHS will closely monitor the progress
of NCPDP's developing a standard medication history message for
communication from a payer/PBM to a prescriber, and provide advice
to the Secretary in time for adoption as a foundation standard and/or
readiness for the 2006 pilot tests.
Observation 9 (Clinical Drug Terminology): Today's e-prescribing
systems support free text entry of a clinical drug and/or selection
of a clinical drug code from one of several proprietary terminology
systems. A standard terminology[16]
for clinical drugs facilitates automated drug utilization review
(DUR) and decision support for patient safety. It is also necessary
for interoperability among different e-prescribing systems. However,
it is recognized that not every item ordered by a prescription will
always be included in a terminology (e.g., compounded drugs, devices,
and supplies). This means that the ability to enter free text in
an e-prescribing system must be preserved.
The National Drug Code (NDC) is used by dispensers to identify
packaged drugs. However, NDC is not appropriate for use by prescribers
in describing the clinical drug. To address this need, the NLM has
produced a clinical drug terminology, RxNorm.[17] RxNorm provides links from clinical drugs to
their active ingredients, drug components, and most related brand
names. Preliminary analysis of the prescriptions written by the
Department of Defense (DOD) found that of the 1,000 most commonly
written prescriptions, the NLM matched 974 to RxNorm codes.[18]
Fully comprehensive RxNorm terminology for all marketed drug products,
including generics, repackaged products, and over-the-counter medications,
will not be available until structured product labels (SPL)[19]
become available to the NLM from the FDA. The RxNorm contains sufficient
codes to be included in the 2006 pilot tests. When the SPLs become
available, it is the intent of the NLM to update the repository
of drug information on a daily basis (as the DailyMed). Additionally,
until the full set of brand names is included in RxNorm, some "dispense
as written" prescriptions cannot be accommodated through e-prescribing.
NCVHS further observes that the FDA is looking to the Department
of Veterans Affairs (VA) National Drug File-Reference Terminology
(NDF-RT) to provide drug classifications for use in the SPL. In
addition, the MMA directed HHS to request the United States Pharmacopoeia
(USP) to develop model guidelines for drug categories and classes
that the prescription drug program sponsors participating in Medicare
Part D can use in structuring their formularies.
NCVHS documented deficiencies in the NDC that must be overcome
to support many clinical applications, including e-prescribing,
in its Report to the Secretary on Uniform Standards for Patient
Medical Record Information, dated July 6, 2000. NCVHS recommended
adoption of the RxNorm in the core set of clinical data terminologies
in its Letter to the Secretary on Recommendations for Patient Medical
Record Information Terminology Standards, dated November 5, 2003.
Recommended Action 9.1: HHS should include in the 2006 pilot
tests the RxNorm terminology in the NCPDP SCRIPT Standard for new
prescriptions, renewals, and changes. RxNorm is being included in
the 2006 pilot tests to determine how well the RxNorm clinical drug,
strength, and dosage information can be translated from the prescriber's
system into an NDC at the dispenser's system that represents the
prescriber's intent. This translation will require the participation
of intermediary drug knowledge base vendors until the RxNorm is
fully mapped.
Recommended Action 9.2: HHS should accelerate the promulgation
of FDA's Drug Listing rule and hence the ability to support the
correlation of NDC with RxNorm (e.g., for passing daily updates
of the SPL to NLM for inclusion in the DailyMed). Timely rulemaking
is critical to sustain the daily use of RxNorm beyond the 2006 pilot
tests.
Recommended Action 9.3: HHS should ensure that, if the Medicare
Part D Model Guidelines and NDF-RT differ, an accurate mapping exists
so they both can be used successfully.
Observation 10 (Structured and Codified SIG): Patient instructions
for taking medications are placed at the end of a prescription.
These are called the signatura, commonly abbreviated SIG.
Structured and codified SIGs will enhance patient safety, although
it is also recognized that free text capability must be preserved
for special circumstances. NCPDP, HL7, and others are working on
addressing structured SIG components and plan to seek broad industry
participation.
Recommended Action 10.1: HHS should support NCPDP, HL7,
and others (especially including the prescriber community) in addressing
SIG components in their standards. This should include preserving
the ability to incorporate free text whenever necessary (e.g., for
complex dosing instructions, and to address special cultural sensitivities,
language, and literacy requirements).
Recommended Action 10.2: HHS should include in the 2006
pilot tests the structured and codified SIGs as developed through
standards development organization efforts.
Observation 11 (Dispenser Identifier): The NCPDP Provider
Identifier Number has been in use for a number of years and is widely
accepted as the dispenser (pharmacy) identifier. Its database contains
information to support various claims processing functions, and
it needs to continue to be available for this purpose. The NCPDP
database can accommodate the National Provider Identifier (NPI)
as a reference field. HIPAA requires the NPI, when it becomes available,
to be used in the NCPDP Telecommunication Standard for claims processing.
The National Provider System (NPS) enumerates pharmacy organizations,
subparts of organizations at a particular address, and pharmacists.
Recommended Action 11.1: HHS should ensure that the NPI,
when it becomes available, is incorporated as the primary identifier
for dispensers in the NCPDP SCRIPT and other e-prescribing standards.
Recommended Action 11.2: HHS should accelerate the enumeration
of all dispensers to support transition to the NPI for e-prescribing.
Recommended Action 11.3: HHS should permit the industry
to use the NCPDP Provider Identifier Number in the event that the
NPS cannot enumerate dispensers in time for Medicare Part D implementation.
Recommended Action 11.4: HHS should evaluate how mass enumeration
of dispensers for the NPI can occur using the NCPDP Provider Identifier
Number database.
Recommended Action 11.5: HHS, when requiring the NPI as
the primary identifier for dispensers, should protect the ability
to maintain linkages to the NCPDP Provider Identifier Number database
for current claims processing purposes.
Observation 12 (Prescriber Identifier): There is no single
identifier for prescribers. The Drug Enforcement Administration
(DEA) Number is widely used as a proxy. Although testimony is expected
to be heard from the DEA between now and March 2005, others indicated
that the DEA prefers the number to be reserved for use only on prescriptions
for controlled substances. NCPDP created HCIdea for the purpose
of enumerating prescribers in order to eliminate usage of the DEA
on prescription claims when transmitted between dispensers and payers/PBMs.
It is not currently made available directly to prescribers. The
HCIdea database supports all of a prescriber's DEA numbers, practice
locations, and the National Provider Identifier (NPI), when it becomes
available. The NPI is the HIPAA standard for identifying all providers,
including prescribers, on all HIPAA transactions. The NPI database
could accommodate a bulk load from HCIdea to include missing elements,
if efficient and valid to do so.
It is further noted that the DEA is anticipated to produce an electronic
signature standard to ensure the protection of messages containing
prescriptions for controlled substances. Electronic signatures will
also be addressed by NCVHS in subsequent recommendations.
Recommended Action 12.1: HHS should ensure that the NPI,
when it becomes available, is incorporated as the primary identifier
for prescribers in the NCPDP SCRIPT and other e-prescribing standards.
It should be noted that the NPI must be at the individual prescriber
level, because a prescription cannot be written at a group level.
Recommended Action 12.2: HHS should accelerate the enumeration
of all prescribers to support transition to the NPI for e-prescribing.
Recommended Action 12.3: HHS should permit the industry
to use the NCPDP HCIdea in the event that the NPS cannot enumerate
prescribers in time for Medicare Part D implementation.
Recommended Action 12.4: HHS should work with the industry
to identify issues and possible solutions that deal with all elements
of the prescriber location and include those solutions in the 2006
pilot tests.
Recommended Action 12.5: HHS should evaluate how mass enumeration
of prescribers for the NPI can occur using the NCPDP HCIdea database.
Recommended Action 12.6: HHS, when requiring the NPI as
the primary identifier for prescribers, should protect the ability
to maintain linkages to the NCPDP HCIdea database for e-prescribing
routing functions.
Observation 13 (Pilot Test Objectives): NCVHS has observed
that there were many impediments to full adoption and implementation
of the HIPAA transactions and code sets standards. With the requirements
for pilot testing in e-prescribing, HHS has the opportunity to address
any similar impediments that might arise with e-prescribing standards
implementations. As previously noted, while the foundation standards
being recommended here are suitable for early industry adoption,
there are several areas in the foundation standards that do not
support all the MMA requirements. In addition, there are a number
of patient and prescriber-specific issues which must be studied
and addressed, for example, acceptance and satisfaction. It must
also be recognized that the success of the pilots will require much
work by the vendors to incorporate new standards and functionality
into their applications before they can be pilot tested.
Recommended Action 13:1: HHS should support the efforts
of standards development organizations to incorporate in the foundation
standards as many as possible of the additional functions required
for MMA, as identified in these recommendations.
Recommended Action 13.2: HHS should include foundation standards
with as many as possible of the additional functions required for
MMA in the 2006 pilot tests.
Recommended Action 13.3: HHS should immediately begin to
work with the vendors to ensure readiness for the pilot tests on
January 1, 2006.
Recommended Action 13.4: HHS should identify and widely
publicize specific goals, objectives, timelines, and metrics to
guide the design and assessment and increase industry awareness
of the 2006 pilot tests. HHS should include metrics that address
economic, quality of care, patient safety, and patient and prescriber
satisfaction factors.
Recommended Action 13.5: After the pilot tests, HHS should
develop and widely disseminate information concerning any economic
and quality of care benefits of e-prescribing, provide comprehensive
education on implementation strategies, describe how e-prescribing
can be implemented consistent with the privacy protections under
HIPAA, and address other elements that contribute to successful
and widespread prescriber adoption and patient acceptance.
Observation 14 (Support for Standards Collaboration): A
significant level of collaboration is occurring among standards
development organizations and with vendors who have proprietary
solutions as there is growing momentum for e-prescribing and other
components of the National Health Information Infrastructure (NHII).
It is important to support the open, consensus-based, and voluntary
nature of standards development organizations, while accelerating
the process of standards development and coordination.
Recommended Action 14.1: HHS should financially support
standards coordination activities to ensure a seamless e-prescribing
process across provider domains (e.g., physician office, hospital,
long term care), dispensers, and payers/PBMs.
Recommended Action 14.2: HHS should encourage standards
development organizations to adopt a change management process that
permits versions to maintain interoperability.
Observation 15 (Policies to Remove Barriers): Testimony
identified widespread industry concerns relating to safe harbor,
preservation of provider/patient choice, and freedom from commercial
bias in messages received through e-prescribing applications[20].
Recommended Action 15.1: HHS should ensure that regulations
define the parameters of safe harbor, ensure preservation of provider/patient
choice, and require that e-prescribing messages received through
e-prescribing applications be free from commercial bias.
Observation 16 (Conformance Testing and Certification):
Testimony identified the need for testing conformance to standards
and certification of e-prescribing systems (i.e., standards conformance,
functionality, and interoperability). While conformance testing
and certification are two distinct, but interrelated, concepts,
it should be recognized that some parts of the industry use the
term "certification" in the limited sense of passing a conformance
test.
Recommended Action 16.1: HHS should support standards development
organizations in their development of conformance tests for the
e-prescribing standards and their implementation guides.
Recommended Action 16.2: HHS should require that e-prescribing
system vendors validate the conformance of their e-prescribing messages.
Recommended Action 16.3: The HHS Office of the National
Coordinator for Health Information Technology should investigate
how e-prescribing applications might best be certified.
Next Steps
There are several other message format, terminology, and identifier
standards and important related issues that were identified by NCVHS
but that are not addressed in this initial set of recommendations.
NCVHS plans to receive testimony on as many of these topics as possible
between now and March 2005; and make further recommendations in
March 2005. The topics include:
-
Electronic signature for use in e-prescribing.
-
Issues relating to privacy and security with respect to e-prescribing.
- A directory that would identify prescribers, nursing facilities,
and pharmacies that are able to accept e-prescribing transactions.
- Codification of allergens, drug interactions, and other adverse
reactions to drugs.
- Incorporation of indications for drug therapy into e-prescribing
messages.
- A standard for units of measure.
- Methods for patient identification for e-prescribing.
- Use of the National Health Plan ID for e-prescribing.
- Formulary identifier.
- Exchange of medication history among all participants in the
e-prescribing process.
- Exchange of medical history within the e-prescribing process.
- How best to ensure the interoperability among e-prescribing
standards.
- Standard codes for orderable items (such as insulin supplies).
- Exchange of drug labeling and drug listing.
- Clinical decision support in e-prescribing.
NCVHS wishes to thank you for the opportunity to make these recommendations.
NCVHS would be pleased to review and comment on plans for the 2006
pilot tests.
Sincerely yours,
