Clinical Decision Support in Electronic Prescribing: Recommendations and an Action Plan

Report of the Joint Clinical Decision Support Workgroup
Jonathan M. Teich, MD, PhD, Jerome A. Osheroff, MD, Eric A. Pifer, MD, Dean F. Sittig, PhD, Robert A. Jenders, MD, MS, and the CDS Expert Review Panel


Clinical decision support (CDS) in electronic prescribing (eRx) systems can improve the safety, quality, efficiency, and cost-effectiveness of care. However, at present, these potential benefits have not been fully realized. In this consensus white paper, we set forth recommendations and action plans in three critical domains: (1) advances in system capabilities, including basic and advanced sets of CDS interventions and knowledge, supporting database elements, operational features to improve usability and measure performance, and management and governance structures; (2) uniform standards, vocabularies, and centralized knowledge structures and services that could reduce rework by vendors and care providers, improve dissemination of well-constructed CDS interventions, promote generally applicable research in CDS methods, and accelerate the movement of new medical knowledge from research to practice; and (3) appropriate financial and legal incentives to promote adoption.

Executive Summary and Primary Recommendations

  • Clinical decision support (CDS): providing clinicians or patients with clinical knowledge and patient-related information, intelligently filtered and presented at appropriate times can improve the safety, quality, efficiency, and cost-effectiveness of care when applied to electronic prescribing (eRx) systems. However, at present, these potential benefits have not been fully realized.
  • Advances in the capabilities, usability, and customizability of CDS systems, new mechanisms to provide access to current knowledge, accelerated implementation of standards and coding systems, and appropriate incentives for use are all necessary to realize the full positive impact of CDS on health care.
  • Advances in CDS system capabilities can be further divided into four areas: the state of the knowledge base (the set of rules, content, and workflow opportunities for intervention); necessary database elements to support CDS; operational features to promote usability and to measure performance; and organizational structures to help manage and govern current and new CDS interventions.
  • The Joint CDS Workgroup set out a series of proposals for these advances based on previous research and practical considerations; these were reviewed by the CDS Expert Review Panel in several phases.
  • Detailed recommendations are set forth for each of these proposals, based on feasibility and potential impact on patient safety and quality of care ([triangle]). The recommendations describe CDS features of basic (minimally acceptable) and advanced eRx systems. Basic and advanced recommendations are outlined for application in 2006 and 2008, reflecting a reasonable expectation of what can be developed and implemented by each target date.
    Table 2.
    Recommended Features and Elements Needed for an eRx System to Provide Effective, High-Value CDS
  • These feature recommendations should be considered when deciding criteria for certification of eRx systems (and implementations) that will be eligible for government demonstration programs and incentive support.
  • Certain enhanced or new standards and vocabularies must be adopted to make development and implementation of effective CDS feasible. Considerable work has been done in this area by government and industry groups, and the National Committee on Vital and Health Statistics has distilled this work into initial recommendations for standards adoption in its September 2, 2004 letter to the Secretary of Health and Human Services. Further recommendations presented here expand on that work by adding more detailed needs and requirements and by proposing potential government actions to promote adoption and practical implementation of these standards ([triangle]).
    Table 3.
    Structures, Standards, and Other Enablers for Practical Development and Implementation of Effective CDS
  • This white paper also outlines a number of centralized structures, standards, and other enablers that are necessary to avoid rework by vendors and care providers, to improve sharing and dissemination of well-constructed CDS interventions, to improve the generalizability of research in CDS methods, and to accelerate the path of new knowledge from research to practice ([triangle]).
  • Recommendations are set forth concerning financial, legal, and other incentives that could allay concerns about adopting CDS and accelerate its implementation ([triangle]).
    Table 4.
    Incentives and Protections to Support CDS Adoption
  • CDS impact increases as more types of data and workflow are combined together in a single system or interoperable set of systems. While benefits can be obtained from standalone eRx systems, progression to (or close interoperability with) a more comprehensive electronic health record is necessary to reap the full spectrum of benefits.
  • Further work is needed to accelerate development of the structures and enablers, to make use of these recommendations in determining eligibility for government programs and incentives, and to consider the application of these recommendations to other clinical workflows outside of eRx. Specific next steps are listed at the end of this white paper. Ongoing collaboration among key agencies and organizations to move this agenda forward has been initiated.

White Paper Purpose

The Office of the National Coordinator of Health Information Technology (ONCHIT) of the Department of Health and Human Services (DHHS) requested the development of this white paper to help guide federal government activities concerning CDS in eRx and related domains.

The DHHS plays a major role in financing and regulating health care in the United States as well as in improving its quality. Ensuring that clinicians and consumers/patients use high-quality, timely, relevant medical information to guide their health care decisions is essential for improved quality of care, patient safety, and appropriate use of resources. The DHHS therefore has a strong interest in the availability and intelligent delivery of this medical information through CDS. More specifically, the Medicare Modernization Act of 2003 (MMA)1 calls for the Secretary of the DHHS to develop standards and guidelines for eRx systems that will be supported under the MMA. Appropriately developed and disseminated, CDS is an important ingredient in achieving the care improvements that these systems are expected to deliver.

This white paper provides recommendations for actions at a national level to help optimize the value and increase the use of CDS, particularly in eRx systems. Specifically, it discusses

  • The components that should be available in basic and advanced CDS systems for eRx in 2006 and in 2008 (summarized in [triangle]). These components include operational features to support greater application of CDS; basic data elements needed to support CDS; local governance and management elements; and the specific classes of interventions, rules, reference information, and other knowledge that should be present in capable systems.
  • Considerations for determining whether specific systems meet these recommendations, for possible use in certification of such systems for federal programs such as demonstration projects and pay-for-performance incentives.
  • Standards and vocabularies that must be developed further and/or accepted to support effective CDS ([triangle]).
  • Initiatives and structures that could be developed at a national level to efficiently support dissemination and sharing of CDS interventions and to accelerate the movement of research findings into practice ([triangle]).
  • Incentives and protections that could be implemented to increase the adoption of effective CDS ([triangle]).
  • A set of next steps and actions for moving these recommendations forward.

This white paper focuses on benefits that can be realized specifically by CDS features, as opposed to those that accrue strictly from implementation of the underlying eRx infrastructure (such as legible prescriptions). Users and beneficiaries of the CDS interventions discussed in this report include clinicians, patients, pharmacists, pharmacy benefit managers, and payers.

Definition of Clinical Decision Support

Clinical decision support has been defined somewhat differently by different authors. Braden et al.,2 following Langton et al.,3 define it as “computer software employing a knowledge base designed for use by a clinician involved in patient care, as a direct aid to clinical decision making.” Perrault and Metzger4 emphasize the relationship of knowledge to data in their definition: “a set of knowledge-based tools that are fully integrated with both the clinician workflow components of a computerized patient record, and a repository of complete and accurate data.” In previous work,5 we have adapted these and other writings to establish a definition in functional terms: “providing clinicians or patients with clinical knowledge and patient-related information, intelligently filtered and presented at appropriate times, to enhance patient care.” This includes not only the familiar reactive alerts and reminders (such as alerts for drug allergies and drug–drug interactions), but also many other intervention types, including structured order forms that promote correct entries, pick lists and patient-specific dose checking, proactive guideline support to prevent errors of omission (such as ensuring that appropriate patients are placed on aspirin), medication reference information for prescribers and patients, and any other knowledge-driven interventions that can promote safety, education, workflow improvement, communication, and improved quality of care.

A detailed treatment of clinical decision support in eRx, including practical issues of classification, usability, implementation, and evaluation, is presented as a chapter in the eHI consensus report Electronic Prescribing: Toward Maximum Value and Rapid Adoption.6 That report describes and references several ways of classifying CDS interventions7,8 based on when in the process the logic is executed, how it is delivered, and the global impact that it has on the process. A conceptual framework for evaluating outpatient eRx applications based on functional capabilities recently proposed by Bell et al.9 is an important step toward understanding variable CDS in this domain.

Clinical Decision Support Benefits

There are well-documented problems with the appropriate, safe, and cost-effective use of medications in health care.10,11,12 The very structure of most eRx applications, such as using standard drug dictionaries, selecting parameters from lists, and having required fields, can alleviate some of the problems associated with generating and filling medication prescriptions.6 However, supplementing this structure with CDS interventions aimed at those who enter, edit, and manage prescriptions offers greater leverage for achieving optimal patient care ([triangle]).

Table 1.
Sampling of Health Care Objectives That Can Be Addressed with Clinical Decision Support

Various efforts to enhance prescription management through CDS have been implemented and evaluated over the past few decades, but historically these efforts have been limited primarily to a small number of academic settings.13,14,15 More recently, CDS-enabled eRx is becoming more widespread in commercially available systems and more widely used in practice (see below). However, use of eRx itself is still at modest levels, estimated at 8% to 18% of physicians, and many eRx systems do not include all the necessary and desired features for thorough, high-value, efficient CDS application. Thus, there are substantial opportunities to further realize the potential for CDS to help achieve the objectives in [triangle]. The recommendations in this report are intended to help close this gap.

Current and Desired State

Before and After Scenario

In the current state of medical practice, the ambulatory care clinician typically uses paper charts to retrieve patient information and a prescription pad to write prescriptions. The process often proceeds as follows:

Before Clinical Decision Support

Patient X is a 62-year-old woman with diabetes, borderline kidney failure, and high blood pressure. She has been seeing her primary care physician, Dr. Smith, for the past three years and has generally been pleased with her care. She arrives at the office for a visit, checks in at the front desk and then is ushered into an examination room. A few minutes later, Dr. Smith walks into the room to see her. He is carrying her paper chart, and he flips through it as they discuss her current issues. After some discussion and a brief examination, Dr. Smith determines that patient X has a sinus infection. He glances at the medicines that she is taking and his last written note about drug allergies and then handwrites a prescription for an antibiotic.

Patient X then leaves the office with the written prescription and takes it to her pharmacy. The pharmacist puts the prescription into his computer and then informs patient X that the antibiotic is not covered on her benefit plan. Patient X goes back home and places a call to Dr. Smith's office. She speaks to a nurse who has a brief conversation with Dr. Smith, who prescribes an alternative antibiotic; the nurse then calls the new prescription in to the pharmacy. The next day, after a difficult night dealing with the symptoms of sinus infection, patient X goes back to the pharmacy. She receives some instructions from the pharmacist about how to take the drug and then returns home.

That evening she takes the first dose of the drug, and an hour later, she develops severe vomiting. Patient X calls her doctor's office again to report the new problem. When the message reaches Dr. Smith, he considers that perhaps the drug was given in too high a dose given her age and kidney function. He prescribes an antinausea medicine and yet another antibiotic. The antinausea medicine eventually controls her vomiting but makes her very sleepy, so much so that when she gets up that evening to go to the bathroom, she stumbles and falls, breaking her hip. She is taken to the hospital by ambulance and undergoes surgery the next morning to have her hip pinned.

When we first wrote this scenario, we were concerned that it was overly dramatic. However, we were quickly able to identify many real cases with consequences that were just as serious or even more so. Serious problems, leading to hospital admission and increased morbidity and mortality, occur frequently because of medication prescribing problems. The current state of medicine relies far too heavily on the memory of the practicing physician, both for important patient data and for relevant clinical knowledge. When Dr. Smith prescribed the first antibiotic, he needed to know the significance of the other drugs that the patient was taking, details about the dosing of that antibiotic for an older diabetic with kidney problems, the up-to-date formulary list of her medication benefit plan, and any details of her medication history that might preclude the use of a given medication. Given that physicians (and other prescribers such as nurse practitioners and dentists) are making these complex decisions several times per day in an environment where the number, complexity, and toxicity of drugs continue to expand rapidly, it is easy to see how the practicing physician needs more support.

After Clinical Decision Support

If the recommendations in this white paper are enacted, this scenario would play much differently:

Patient X arrives for her office visit. The nurse brings her back to the examination room and puts a preliminary diagnosis of “sinus infection” into the computer. Dr. Smith arrives to see her a few minutes later. After examining her and confirming the preliminary diagnosis, Dr. Smith clicks a button to reveal an evidence-based recommendation on the best antibiotic options for this condition. The computer returns a list of three antibiotic choices; next to each choice is an icon indicating whether that medication is covered on patient X's plan. The first antibiotic is off-formulary, so Dr. Smith selects the second antibiotic. The computer checks the patient's other active medications, and an alert window pops up indicating that the drug may interact with one of her diabetes drugs, resulting in vomiting (in fact, it was this interaction, not the patient's age or kidney function, which was responsible for patient X's vomiting in the first scenario; in that scenario, the physician never did make this connection).

Dr. Smith contemplates giving her the adjusted dose of the drug and treating through the risk of vomiting. To be sure, though, he clicks a button revealing her drug history over the past 3 years. He notes that one of his partners gave a similar drug to her last year and the result was, indeed, severe nausea and vomiting. Armed with this highly relevant history, Dr. Smith cancels the drug order and selects the third antibiotic. No warnings appear this time, but the computer does recommend an adjusted dose based on her age and last measured kidney function, which Dr. Smith accepts. He confirms the prescription with a click, which directs the prescription to be electronically transmitted to the patient's local pharmacy and which also prints a concise patient's guide to the drug and its potential side effects. He reviews the prescription, dose, and potential side effects with patient X and prepares to discharge her from the office.

Before sending her home, however, he notes that the computer, which includes a full electronic health record as well as an eRx function, is recommending that the patient be placed on a cholesterol-lowering drug, based on her most recent cholesterol and LDL results and her diagnosis of diabetes; the system again shows which of the applicable drugs is on the patient's plan formulary. With two clicks, Dr. Smith prescribes this medication as well, again following the computer's recommended adjustment for age and kidney function. The computer also recommends a follow-up blood test (creatine kinase) after four weeks of therapy because of the potential risk of muscle inflammation with this family of drugs. With one click, Dr. Smith orders this blood test and instructs the patient to return next week to get the test done. The rest of patient X's course remains uneventful, and she recovers rapidly from her sinus infection without further incident.

Current State of Clinical Decision Support–enabled Electronic Prescribing


Data on the prevalence of eRx itself, let alone the prevalence of eRx with CDS, are difficult to obtain with great precision, but estimates are available. A January 2003 survey by Boston Consulting Group found that 16% of U.S. physicians are using eRx, although another 21% said they plan to start using it within 18 months.16 A variety of surveys have demonstrated an increase in the number of practices interested in and/or actually using electronic medical records (EMR's),* both in large or hospital-connected practices and also in small, independent practices,17,18,19 although these surveys do not specifically count the use of eRx within the EMR. Data suggest that a significant majority of eRx is currently done within the context of an EMR rather than through a stand-alone eRx system.


Bell and colleagues9 and Schiff and Rucker20 have attempted to identify and classify the significant elements of eRx systems, including some elements of CDS. More recently, Wang et al.21 led a RAND Corporation field study that assessed the capabilities of ten commercially available eRx systems in 2002 and 2003. The data collected from this study provide information on implementation levels for 28 of the recommended CDS system features discussed later in this white paper. Preliminary results indicate that, in the mean, each product included 64% of the “Basic 2006” features (those features deemed by our panel to be essential for all systems by 2006), 34% of the “Advanced 2006” features, and only 12% of the “Basic 2008” and “Advanced 2008” features.

Taking all these studies together, we can conclude that eRx is growing in popularity but is still only found in a relatively small minority of U.S. practices, and even where it is used, available systems have many, but not all, of the most basic essential CDS features; advanced, higher value features are found in only a minority of commercially available systems. Thus, a majority of U.S. patients are not yet reaping the safety and quality benefits that can come from eRx with CDS.

Removing Barriers

A number of barriers impede the optimal adoption and effectiveness of CDS interventions for medication management. Some of these barriers in currently available applications include:

  • functionality: limited CDS feature/function; usability problems;
  • data: lack of integration to important data from the EHR;
  • knowledge: uneven availability, standards, and management of best-practice CDS knowledge;
  • costs: for implementation and ongoing use, as well as perceived liability concerns.

Table 5 (available as an online data supplement at www.jamia.org) contains a more detailed listing of these barriers, along with potential high-level solutions.

In general, there are three areas where action is necessary to bring the current state of CDS closer to the desired state:

  • Determine and encourage core CDS functionality in all products, including knowledge, database elements, functionality and usability features, and organizational matters.
  • Enhance the knowledge management infrastructure for eRx-related CDS, making it possible for more providers to have access to references, rules, and guidelines that are comprehensive, high-quality, usable, actionable, and configurable. Enhancing this infrastructure will also make it possible to do broadly applicable research on the effectiveness of specific CDS methods. Closely related to this is the need to have enhanced standards and vocabularies for a variety of CDS-related eRx operations.
  • Provide incentives, financial, regulatory, and legal, for implementation and use of CDS-enabled eRx.

The next sections present detailed recommendations in each of these areas.


Method of Determining Recommendations: The Clinical Decision Support Expert Review Panel Process

The Joint CDS Workgroup, tasked with the development of the recommendations, assembled an expert panel to help ensure that the recommendations in this report reflect broad input from the many different stakeholders in the prescribing and medication management process as well as from experts on clinical quality and informatics and from representatives of major health care information thought leadership organizations. The CDS Workgroup compiled an initial draft list of recommendations for the tables in this white paper. Expert panelists reviewed early drafts and provided comment. About 25 of the panelists convened in a half-day meeting at the Medinfo conference in San Francisco on September 9, 2004, during which the recommendations were discussed extensively, resulting in additions, deletions, reassignments, and clarifications of many items. The resulting version went through two more rounds of review with the panelists via e-mail, including editing between each round by CDS Workgroup members, to yield the final recommendations presented here.

These recommendations have been presented in preliminary form to the Subcommittee on Standards and Security of the National Committee on Vital and Health Statistics for its use as it considers standards and guidelines for rule making pursuant to the MMA. In addition, because the recommendations are clearly applicable to potential certification of eRx and electronic health record systems, they have been shared in preliminary form with the newly formed CCHIT.

Core Features to Support Clinical Decision Support

Certain features of eRx systems can help ensure that knowledge and data are effectively used for safe, high-quality, cost-effective medication management. These recommendations fall into four areas:

  • Knowledge base: the types of rules, content, and interventions that are available in the system
  • Database: necessary data elements needed to permit targeted, patient-specific, event-specific CDS
  • Functionality and usability: aspects of the day-to-day operation of the eRx system that must be considered and implemented to make it acceptable, implementable, and efficient
  • Organizational: governance, communication, policy, and management structures and processes that are essential for effective, appropriate use of CDS on an ongoing basis

The recommendations in each of these areas are divided into features expected of basic (minimally acceptable) and advanced eRx systems, and they are further divided to indicate features expected of eRx implementations in 2006 and those expected by 2008. Essentially, basic CDS functionality would be expected of all capable eRx systems implemented on or after the target date. Advanced functionality is that which clearly adds to the effectiveness and benefit of CDS; systems containing several elements of advanced functionality should be considered for increased favor through additional incentives.

These recommendations could be used as part of the health information technology certification process as it evolves. CCHIT is not specifically working on eRx in its first phase. Commission members, including the chair, have expressed interest in making use of this white paper's recommendations in ongoing CCHIT work, and in facilitating ongoing collaboration between CCHIT and the joint CDS Workgroup. In addition, these recommendations are intended to help guide requirements for participation in federal eRx activities under the MMA, such as demonstration projects and pay-for-performance programs.

The infrastructure required to fulfill the recommendations in the “organizational” column will vary from one site to another, but there are common themes and guidelines that can help. In particular, the Clinical Decision Support Implementers' Workbook5 contains a step-by-step guide to identifying stakeholders, understanding communications channels, setting goals, and establishing the necessary organizational structures for CDS implementation.

Standards, Structures, and Enablers

In addition to requiring specific features in individual eRx systems, there are other crucial elements of common infrastructure needed to support effective CDS nationwide.

Standards and Terminologies

Enhanced or new standards are required in several areas to facilitate CDS. These include mechanisms for systems from different vendors to exchange data; information transfer among providers, pharmacists, payers, and pharmacy benefit managers; and reconciliation of conflicting prescription standards from different states. Standardization also needs to be applied to terminologies: there is a need for convenient, usable, standard dictionaries for medication ordering that support typical usage; standard terminologies must also be established for common representation of medication doses, frequencies, allergies, and reactions.

Standards were explored in great detail in the eHI report6 that was presented to NCVHS on March 30, 2004. Using this report and many other sources of information in its deliberations, the NCVHS Subcommittee on Standards and Security provided initial recommendations for standards adoption in its letter of September 2, 2004, to the Secretary of DHHS. The recommendations here expand on those by adding more detailed needs and requirements and by proposing government actions to promote adoption and implementation of these standards.

Structures and Methods for Exchanging Clinical Decision Support Content

The CDS Expert Review Panel endorsed the concept of knowledge clearinghouses and related standards. Clearinghouses would enable CDS knowledge and corresponding implementation information to be widely accessible in a practical and standard format that facilitates its use in health care information systems. The primary goal of the clearinghouse model is to avoid rework by vendors and care providers in CDS content development and dissemination, to reduce errors and improve efficiency in implementing CDS interventions, and to accelerate the practical use of new knowledge from the medical literature. An additional goal is to reduce discrepancies that exist today among knowledge bases used in clinical applications; by some reports, these discrepancies are substantial and may be clinically significant.

Medical societies, health care organizations, informatics groups, knowledge vendors, and other stakeholders could all contribute to providing content to such clearinghouses. Government agencies could be important content contributors as well. However, rather than having a single government-controlled source of knowledge, the favored model would permit the publishing of multiple knowledge sets or clearinghouses by different agencies and groups, using a common structure. Local clinicians and managers would be able to select and configure specific interventions that are applicable to their situation.

Some specifics related to this concept have been briefly explored by the panel, including required elements, authorization, indicating level of evidence, organizational endorsements, and exchange standards. Considerable additional thought has been given to the concept by the CDS Workgroup, and the Workgroup has begun laying the foundation for further collaborative discussions and follow-on work, involving a variety of stakeholders.

[triangle] lists the recommendations for structures, standards, and other enablers that should be developed in a centralized or collaborative fashion to support effective, widely available CDS. Along with the specific suggested action items, we list possible government actions to promote and accelerate each item, and the time frame (based on [triangle]) when they are needed.

Incentives and Related Issues

It is widely believed that adoption of eRx itself needs to be driven by financial, regulatory, and/or accreditation incentives. This is because providers bear a disproportionate share of the cost of implementing and using an eRx system, relative to the intrinsic financial benefits that accrue from its use (as outlined in the Center for Information Technology Leadership's report on ambulatory computerized physician order entry10). Specific incentive programs have been discussed in the eHI eRx report6 and expanded further in the March 2004 white paper produced by Rosenfeld et al.22 for the same organization. These reports contain substantial information on the foundation and the business case for eRx and CDS; we have used them as the jumping-off point for this brief discussion of practical action items.

Recommendations in [triangle] focus on three areas that the panel considered to be feasible, to address significant barriers to adoption, and to be specific to the use of effective CDS:

  • Protection from increased liability for providers who use suitably strong CDS systems (a point of considerable controversy; the recommendation here calls primarily for an active debate on a number of possible options)
  • Malpractice benefits for providers who use CDS systems
  • Incentive funding for use of systems meeting appropriate certification criteria

In addition, the CDS Expert Review Panel discussed mechanisms for carrying out certification of individual systems. One important controversy here is the question of whether certification should be based on a review of documented and validated system specifications, by performance in a test suite, or by performance and/or outcome metrics from actual use. The first method is easier to undertake but may not accurately reflect real-world performance; the second and particularly the third methods more closely characterize system benefits but are more difficult to implement. We recommend that the first method should be used for the initial stage of certification implementation but that there should be steady and prompt progress toward test case and actual occurrence reporting (see [triangle]). Additionally, evaluating performance and outcomes of CDS-enabled eRx in actual practice may be dependent on local clinical conditions and patient mix. We have ceded this discussion to the newly formed CCHIT, which is specifically charged with deciding such issues; however, CDS Expert Panel consensus opinion on these various options has been shared with CCHIT commissioners, and we are maintaining an ongoing discussion with them. We have also shared preliminary versions of the CDS feature recommendations as potential elements for functionality certification.

As in the previous table, each incentive in [triangle] is described with its essential details and accompanied by recommendations for government action to promote its development along with an implementation timeline to keep pace with the recommendations of the previous tables.

Next Steps

Based on ongoing discussions with the various participating government agencies and industry organizations, there are several important next steps to follow from the current work:

Primary Use

  • The NCVHS Subcommittee on Standards and Security received a preliminary presentation of these recommendations on November 4, 2004, and has referenced the material in its most recent round of rule-making discussions concerning the MMA in March 2005.24
  • The CCHIT has asked to use the recommendations on eRx specifically and the methodology of this white paper in general in its own work. The CDS Workgroup intends to work closely with CCHIT as needed.

Review and Dissemination

  • The recommendations in this white paper have been extensively vetted and are available as a source of expert consensus on which actions and decisions can be based. We also encourage further review and ongoing comment by interested and affected parties, particularly as technology and health services research continue to evolve. The CDS Workgroup will seek out forums to present these findings and will work with industry organizations to update the findings as necessary.
  • The participating organizations have supported further dissemination of these findings through publication in the informatics literature.

Further Work

  • The Workgroup will work together with ONCHIT and AHRQ, the primary requesting and supporting organizations for this work, to coordinate and contribute to any necessary follow-on work. In particular, work is required to accelerate a number of the structures and enablers discussed in [triangle]. The Workgroup can provide ongoing input to DHHS on the evaluation and implementation of these ideas.
  • Work on practical classification of CDS interventions is in progress through an update to the HIMSS Clinical Decision Support Implementers' Workbook.5 This resource provides practical guidance on CDS implementation, much of which is pertinent to eRx. The Workgroup will explore mechanisms whereby that guide, or derivatives of it, can be applied toward promoting successful CDS in eRx. The HIMSS CDS Task Force is one potential mechanism for further collaborative discussion and work in these areas.
  • ONCHIT and the CDS Workgroup have expressed a particular interest in exploring the concepts necessary to disseminate knowledge in a standardized and highly practical way for use by CDS applications (see clearinghouse items in [triangle], along with the discussion in text). Further discussions will be held regarding the best way to further this goal.
  • While the specific findings in this white paper concentrate on eRx, the analysis and organization lend themselves to the application of CDS in general. In the industry, an increasing trend has been to consider CDS as a distinct subsystem, applicable to all clinical applications. To fully realize the potential of the “decade of health information technology,” the effective application of CDS in patient management areas beyond eRx needs to be fostered. The CDS Workgroup will endeavor to promote ongoing analysis and recommendations on these other CDS-related opportunities at the national level to improve the quality, safety, and cost-effectiveness of care.
  • At the September 9, 2004, meeting, representatives of the CDS Workgroup, AMIA, HIMSS, eHI, AHRQ, ONCHIT, and CCHIT held initial discussions about the creation of a CDS Collaborative that would work together on projects of common interest. A follow-up task to this work is to further that alliance and to establish plans for a series of collaborative projects, which may include some of the items listed above.
