The Learning Healthcare System: Workshop Summary 8 Structuring the Incentives for Change OVERVIEW A fundamental reality in the prospects for a learning healthcare system lies in the nature of the incentives for inducing the necessary changes. Echoed throughout this report are calls for incentives that are structured and coordinated to drive the system and culture changes, as well as to establish the collaborations and technological developments necessary to build learning into every healthcare encounter. Public and private insurers, standards organizations such as National Committee for Quality Assurance (NCQA) and the Joint Commission (formerly JCAHO), and manufacturers have the opportunity to shape policy and practice incentives to accelerate needed changes. In this chapter, representatives from private and public payer organizations, a manufacturer, and a standards organization give their perspectives on how the field might support specific and broad policy changes that provide incentives for systemwide progress. These perspectives engage only a sampling of the sorts of incentives to development of a learning healthcare system, but they represent important focal points for stakeholder alignment. Alan Rosenberg of WellPoint offers a perspective from the health insurers industry on opportunities for encouraging both evidence development and application. For payers, incentives for change are structured around their three major functions: reimbursement, benefit plan design, and medical policy formation. Rosenberg gives several examples of past and current efforts by insurance providers to encourage evidence generation and application. Steven Phurrough discusses the Centers for Medicare and Medicaid

The Learning Healthcare System: Workshop Summary Services’ (CMS’s) opportunities for influencing change through regulatory and payment processes but also notes that its leadership in implementing policies that assist in developing evidence might encourage similar efforts throughout the healthcare system. A very powerful approach taken by CMS in this respect is Coverage with Evidence Development (CED), in which reimbursement is conditional on the creation or submission of additional data. Phurrough describes recent revisions of CED that define two CED components: Coverage with Appropriateness Determination and Coverage with Study Participation, as well as the range of gaps in the evidence base that such policies may help to fill. Wayne A. Rosenkrans and colleagues discuss the importance of providing incentives for appropriate evidence creation and appropriate use of evidence. Establishing standards of evidence and processes for reimbursement decisions would help manufacturers design better studies and work to provide the evidence needed. In addition, flexibility to account for individual variation needs to be built into the system. Evidence generated must be put to good use through thoughtful structuring of guidelines, decision support, and outreach to providers and patients. New models for product development such as evidence-based drug development will accelerate the creation of a learning healthcare system by making clear breaks with outdated approaches. For example, embedding the creation of effectiveness data into the process of drug development or developing a continuous process of evidence creation in partnership with the regulators and payers might provide sufficient financial incentives to drive change. Margaret E. O’Kane discusses the important role that standards organizations have played in improving the quality of health care by measuring performance and identifies the significant barriers to extending this across the healthcare system: the absence of evidence from basic science, to complex comorbidities, subpopulations, and comparative effectiveness; the lack of usable guidelines; difficulty in obtaining data; and lack of accountability throughout the system. All are significant impediments to improving quality and efficiency of care. O’Kane calls for payment reform, regulatory reform, and liability reform as the key instruments to confront these challenges. System-wide change requires new ways of thinking about gathering, managing, and deploying knowledge and an evolution in our approaches. OPPORTUNITIES FOR PRIVATE INSURERS Alan Rosenberg, M.D. WellPoint Inc. Private insurers have many opportunities to structure the incentives for change both in evidence development and in evidence-based application.

The Learning Healthcare System: Workshop Summary This paper addresses both the private insurance industry as a whole and gives specific examples from my own organization, WellPoint Inc., which provides health benefits through its affiliated companies for 34 million Americans. The area to be covered is very broad, but this overview provides a sense of the opportunities that the private insurers have for collaboration with others in health care to build a learning health-care system for evidence-based medicine. Three major functions of private insurers provide such opportunities: reimbursement and financing methodologies, including reimbursement to physicians, other practitioners, and healthcare institutions, can be and are currently used to structure incentives; claims data through their analysis can be and are used to support this environment; benefit plan design (BPD) and, within BPD, medical policy formation also can be and are used. This paper also discusses two initiatives—data integration for electronic health records (EHRs) and consumer-focused initiatives—along with the methods used, the importance of collaboration, and some of the hurdles from the private insurer perspective in achieving these goals. Private insurers have and will continue to fund significant components of evidence development and evidence-based applications (Blumenthal 2006). Certain of these are still evolving but worthy of special note. Several health plans now provide benefit coverage for individuals in National Institutes of Health (NIH) sponsored trials. The Centers for Medicare and Medicaid Services has recently embarked on a model of coverage based on participation in registries such as the implantable cardioverter defibrillator registry. Several insurers, including WellPoint, helped provide funding for the development of this registry. WellPoint also recently announced its collaboration, including economic support, with the Society of Thoracic Surgeons (STS), for its cardiac surgery registry. Use of the data from these registries to support evidence development and evidence-based care remains a priority. WellPoint uses such data, including data from STS and Joint Commission on Accreditation of Healthcare Organizations (JCAHO) registries to determine variable reimbursement for facilities in a variety of its pay for performance (P4P) programs. Payers recognize that evidence for and analysis of the effectiveness of P4P programs are still under evaluation (Rosenthal et al. 2005). At the same time, payers continue to fund this important and significant modification in traditional insurance-based reimbursement methodology. Today, P4P programs include enhanced reimbursement for physicians who perform better on a wide array of evidence-based measures including mammography rates, immunization rates, diabetic retinal eye exam rates, and rates of measurement of hemoglobin A1c levels. WellPoint has already paid to physicians and medical facilities more than 100 million dollars through these programs. The second area for review is how we can collaborate with others

The Learning Healthcare System: Workshop Summary to advance evidence development through claim data analysis. WellPoint databases have claims history for 34 million Americans and integrated pharmacy claims data on 17 million of these. Through analysis of this dataset, and by other insurers as well, post-market surveillance can be undertaken. WellPoint, with its affiliate HealthCore, did submit information to the Food and Drug Administration (FDA) on cyclooxygenase-2 (COX-2) inhibitor complications based on analysis of this dataset. Health-Core is currently working with a variety of academic research centers and specialty societies on projects using this dataset to evaluate comparative effectiveness including projects on cardiac care, controller effectiveness in asthma, and an analysis of blood growth factors. Some of the individuals and organizations contributing to this workshop summary have worked for years and developed sophisticated models of data analysis. Ongoing efforts and collaborations will continue to tap these valuable resources for evidence development. In addition to WellPoint’s initiatives, the Blue Cross Blue Shield Association (BCBSA) announced its plan to bring together an array of claims datasets that will eventually include claims data on more than 70 millions Americans. Unlike currently available CMS datasets, but similar to WellPoint’s, these data will include integrated pharmacy and medical claims data. Claims data are also an important component in evaluating evidence application. While having many limitations, efficiency is a real advantage of claims-based quality measures. The National Committee for Quality Assurance has catalyzed and significantly supported this effort by the development of standards for quality and preventive health initiatives through its Health Plan Employer Data and Information Set (HEDIS) measurement set. This is an example of a long-term collaboration involving practitioners, insurers, and employers that has significantly moved this field forward. Insurers continue to use this and other nationally developed measurement sets to provide feedback to the practitioner community participating in networks. However the defined datasets remain limited, and ongoing development of broader, nationally recognized, consistently defined, and efficient-to-gather standardized measurement sets needs to continue. In addition to NCQA’s ongoing work, the majority of large insurers continue to actively engage in and support recent efforts by the AQA (previously known as the Ambulatory care Quality Alliance). Benefit plan design and, specifically, medical policy formation support evidence-based application. A key component of most health insurance benefit plans is that covered services are those that are medically necessary and services that are investigational are not covered. The benefit plans are legal contracts, and definitions of “medical necessity” and “investigational” vary, but they are routinely incorporated into these legal contracts. Therefore these definitions are at the core of insurers’ benefit determinations. Based on the benefit plan language, insurers
OCR for page 293
The Learning Healthcare System: Workshop Summary can and do develop evidence-based models for those things that may be considered medically necessary and those that may be considered investigational or not medically necessary. Insurers use inputs from a variety of evidentiary sources, including literature-based review, governmental review bodies, Cochrane reviews, and other technology assessment entities. (See publicly posted coverage or medical policies on numerous BCBSA-affiliated entities and Aetna web sites.) In addition, WellPoint uses specialty society and academic medical center input regarding medical policy and medical necessity determinations, working actively with more than 30 specialty societies. This process is an active effort at developing evidence-based evaluation that includes input from the practice community on when the evidence, in conjunction with national practice patterns, has developed to support benefit coverage. Collaboration in this regard is essential. However, litigation continues to be a significant mitigation in the insurers’ ability to fully apply evidence-based medical necessity benefit determinations. One significant initiative at WellPoint to better support the diffusion of claims information into practice is data integration for electronic health records. This is an effort to use our claim and pharmacy information datasets to support clinical practices. Through this initiative, WellPoint is making available claims-based data regarding diagnoses, procedures, and pharmaceutical information to emergency rooms on a real-time basis. This has already been undertaken in Missouri and is under way in California. Insurers are actively involved in efforts to reengage their members through consumer-directed health plans. Initial evaluations regarding the effect of these programs have been published (Newhouse 2004). Some of the consumer-directed opportunities that these programs offer include disease management programs; web-based information, including films on conditions or procedures; mail-based information that is procedure and disease specific; web-based, paper, and personalized mailings with health information based on combinations of claim and pharmacy information; and safety information on drug recalls and new drug alerts. Health insurers have excellent opportunities to support evidence development and evidence-based application. Private insurers also understand that we are only one part of the mosaic and that better value will be created through collaboration. This collaboration needs to occur across the industry and across the healthcare sector with manufacturers, with government, with academic and medical communities, and with our members to move healthcare delivery to a more evidence-based approach. Examples of collective opportunities include the following: With government: develop national registries, support and conduct research, educate, develop national standards;

The Learning Healthcare System: Workshop Summary With the academic medical community: provide evidence-based care, conduct research, establish evidence-based guidelines, educate practitioners and patients; With members and patients: strengthen demand for evidence-based along with preference-based care; With manufacturers: conduct research, support full publication of data, innovate and bring to market health-enhancing products; and With employers and insurers: enhance individual and physician decision support, integrate data sources, educate, develop performance-based reimbursement plans, and provide evidence-based coverage determinations. There are also significant hurdles faced by insurers. One of the most significant is the litigation environment and the large dollar court settlements that do not align with evidence-based practices. For a bit of context, AHRQ’s budget is approximately $330 million dollars a year, but insurers have had and continue to have $50 million to $100 million dollar settlement costs for failing to provide benefit coverage for an intervention that has inadequate evidentiary support. The most broadly described has been autologous bone marrow transplantation for breast cancer, but new examples occur each and every year. Insurers recognize that we are not viewed favorably in terms of court cases and have very significant risk—this continues to make it difficult for us to maintain strong evidence-based decision making. The opportunity here is to develop some safe harbors built around a national evidence-based process similar to Britain’s National Institute for Clinical Excellence (NICE) (Rawlins 2004). Second, insurers recognize that we are not the healthcare sector that most people come to as a trusted partner for getting health information. These ongoing trust issues with the consumer and medical community make communications by us less effective. We are working hard to transform this perception through continued collaborations, but we recognize we have a way to go. The last significant hurdle that must be addressed is cost. One important example of this is the discussion of conversion from the Ninth Revision of the International Classification of Diseases (ICD-9) to the Tenth Revision (ICD-10). Healthcare researchers generally agree that this will increase the availability of useful clinical information in claim databases. However the cost to systems for conversions is enormous. The ICD-9 to ICD-10 conversion cost to the health insurance industry alone (not including cost to physician practices or hospitals) is estimated to be between $432 million and $913 million, according to a Robert E. Nolan company report and subsequently by independent IBM reports. Therefore careful evaluation of the true value of these changes versus the total cost remains an ongoing

The Learning Healthcare System: Workshop Summary imperative—each dollar spent on this is a dollar that cannot be spent on one of the other initiatives outlined. OPPORTUNITIES FOR CMS Steve Phurrough, M.D., M.P.A. Centers for Medicare and Medicaid Services What opportunities does CMS have to develop policies that can provide incentives for the developments necessary to build learning—evidence development and application—into every healthcare encounter? Issues around trial design, rapid technology advancement, and healthcare culture are crucial and of concern to CMS, and have been discussed in earlier chapters. This discussion focuses on options that CMS has to influence these changes. CMS influences changes either through its regulatory and payment processes or through its leadership role in the healthcare system. Over the last few years, CMS has attempted to use the latter more broadly, with its emphasis on public health and not just paying claims. This role is very important in itself but with better prospects when accompanied with payment or regulatory changes. Prerequisites There are certain prerequisites to these policy changes. For all healthcare experiences to become learning experiences will require some technologies not currently in place. This global population-level learning requires information technology (IT) changes that allow simpler, faster, and more complete data collection and exchanges. Telephonic and paper surveys, multiple data entries, chart reviews for data, and extensive data validations are all impediments to this learning experience. Solutions are complex, but the technology exists. A national standard for the operational architecture for electronic health records is an essential first step. Many facilities, clinics, and offices are hesitant to enter into EHRs, fearful that standards may change and expensive systems become obsolete. While CMS does not have responsibility for this, it is interested in being part of that conversation. Standard definitions for medical terminology are also necessary. Clinical trials, registries, FDA post-market approval studies, and payers do not have consistent definitions of basic medical terms necessary to simplify data collection. An industry-sponsored registry for a particular device may pay for data on a particular patient that also has a requirement to have the same data submitted to a payer. The definitions of the data elements may differ, and hospitals spend significant time sorting out the differences. However,
OCR for page 296
The Learning Healthcare System: Workshop Summary although the time issue is significant, comparing results from the two data collections may not be useful because of this. The Department of Health and Human Services (HHS) has contracted with the American National Standards Institute (ANSI) in cooperation with the Healthcare Information and Management Systems Society, the Advanced Technology Institute, and Booz Allen Hamilton to develop a widely accepted and useful set of standards specifically to enable and support widespread interoperability among healthcare software applications. ANSI created a Healthcare IT Standards Panel (American National Standards Institute 2006) to assist in the development of the U.S. Nationwide Health Information Network (NHIN) by addressing issues such as privacy and security within a shared healthcare information system. This panel recently presented its first set of 30 harmonized standards to the American Health Information Community in October 2006. A number of officials from both the public and the private sectors voiced concerns about the standards. This initial effort demonstrates the difficulty of this task. Much of the learning discussed in this Institute of Medicine (IOM) workshop requires collecting data in ways that may not have the same scientific base as the typical clinical trial methodological sciences. Healthcare research has a fairly well thought out and well designed research methodology, but the research methodology for collecting, analyzing, and utilizing data in other manners—data from claims databases, registries, emerging death data—is much less clear. Increasing the opportunities to collect more information without a good scientific basis for how it will be used—and without broad acceptance in the healthcare community that it is valid evidence—is a fruitless endeavor. Good science behind the use of these types of data is needed. Policies Moving from prerequisites to policy options, CMS has several opportunities that could increase learning. Improving the information included with claims data could rapidly advance knowledge, particularly around safety and adverse events. Moving from ICD-9 to ICD-10 adds a greater level of detail for diagnoses and procedures than we currently have. The success of this option will require providers and coders to accurately select the more definitive diagnoses found in ICD-10. Significant concerns have been raised about the ability of the healthcare industry to track adverse events from medical devices and to notify patients when those events occur or when a recall is initiated. If a particular implantable device is recalled, providers and hospitals have tremendous difficulties in identifying patients who have those devices. Payers, such as Medicare, have significant interest in ensuring that their beneficiaries are notified of
OCR for page 297
The Learning Healthcare System: Workshop Summary the recall. That information is not available to payers. The FDA has begun discussions on an initiative to add unique product identifiers to medical devices, identifiable through bar coding, radio frequency, or other automated techniques. While this would allow easier recording of this information in hospital records, it still does not simplify notification of patients. Having data fields in the claims system that could be populated through the systems required by the FDA would allow payers to notify their beneficiaries when recalls or adverse events occur. In addition, device specific information on claims forms has the potential, when matched with subsequent claims data from patients’ interactions with the healthcare system, to identify other events not recognizable through the current reporting systems. Using claims data is not without problems. Claims forms are payment instruments and are completed with the goal of maximizing payments. In some instances, this may result in a lack of clarity as to the major diagnoses or procedures involved in the care of the patient. Using claims data also makes risk stratification difficult and results in outcomes that do not reflect true practices. Another opportunity that CMS has already employed is to create requirements that condition payment on the submission of additional data. The CMS quality programs are representative of this. Hospitals currently participate in several quality initiatives that were required as a condition of the annual inpatient rate increase. In other instances, CMS has provided additional payment for information—the oncology demonstration is an example of that. CMS is currently working with the public to develop appropriate quality measures for ambulatory services as well. While the collection of this type of information has become de rigueur for CMS and most health plans, it is still challenging to present this information in manner that is beneficial to the public. In early 2005, CMS released a draft guidance document on Coverage with Evidence Development that outlined a policy on requiring additional evidence as a condition of payment. Several National Coverage Determinations (NCDs) over the previous two years had used this option, and the 2005 guidance document outlined how this process would be used in the future. Following extensive public comments and public forums, CMS issued a revised document in the summer of 2006. This revised document answered many of the concerns addressed by the public. In essence, the guidance document outlined two CED components: Coverage with Appropriateness Determination (CAD) and Coverage with Study Participation (CSP). CAD requires additional data collection to ensure that the item or service is being provided in a manner consistent with the guidelines outlined in the CMS reasonable and necessary determination. CAD will be required when CMS is concerned that the data collected on a claims form are insufficient to determine that the item or service was appropriately provided as
OCR for page 298
The Learning Healthcare System: Workshop Summary outlined in the NCD. The following are some concerns that may lead to a coverage decision that requires CAD as a condition of coverage: If the newly covered item or service should be restricted to patients with specific conditions and criteria; If the newly covered item or service should be restricted for use by providers with specific training or credentials; If there is concern among clinical thought leaders that there are substantial opportunities for misuse of the item or service; and If the coverage determination significantly changes how providers manage patients utilizing this newly covered item or service. CSP may be an option in a national coverage determination when CMS does not find sufficient evidence to determine that the item or service is reasonable and necessary under section 1862(a)(1)(A). This option would condition payment on participation of the beneficiary in a clinical research study outlined in the NCD. The following list includes some of the evidentiary findings that might result in CSP: Available evidence may be a product of otherwise methodologically rigorous evaluations but may not have evaluated outcomes that are relevant to Medicare beneficiaries. The available clinical research may have failed to address adequately the risks and benefits to Medicare beneficiaries of off-label or other unanticipated uses of a drug, biologic, service, or device. Available clinical research studies may not have included specific patient subgroups or patients with disease characteristics that are highly prevalent in the Medicare population. New applications may exist for diagnostic services and devices that are already on the market, but there is little or no published research that supports a determination of reasonable and necessary for Medicare coverage at the time of the request for an NCD. Sufficient evidence about the health benefits of a given item or service to support a reasonable and necessary determination is available only for a subgroup of Medicare patients with specific clinical criteria and/or for providers with certain experience or other qualifications. Other patient subgroups or providers require additional evidence to determine if the item or service is reasonable and necessary. CSP research conducted may include a broader range of studies than randomized clinical trials to include observational research. However, all studies must conform to the standards that will be developed by the Clinical Research Policy.
OCR for page 299
The Learning Healthcare System: Workshop Summary In rare instances, for some items or services, CMS may determine that the evidence is very preliminary and not reasonable and necessary for Medicare coverage, but, if the following criteria are met, CSP might be appropriate: The evidence includes assurance of basic safety; The item or service has a high potential to provide significant benefit to Medicare beneficiaries; and There are significant barriers to conducting clinical trials. The implantable cardioverter defibrillator (ICD) registry is one instance where payment for some beneficiaries was conditional on data submission to a registry. Hospitals implanting ICDs for primary prevention are required to submit several data elements to a national registry. This registry was initially managed by one of CMS’ Quality Improvement Organizations. However, this has now been transferred to the National Cardiovascular Data Registry managed by the American College of Cardiology and the Heart Rhythm Society. The first year of the registry resulted in data on almost 45,000 ICD implantations with a compliance rate greater than 95 percent. The initial review of these data produced results not seen in the large trials for these devices. In those trials, no deaths were recorded during the initial hospitalization for the implantation. In the registry, a number of deaths were recorded. This provides a cautionary warning to both patients and providers that ICD implantation is not without risk. The current CED concept limits its use to those few instances in which we believe that the evidence does not support coverage but is suggestive of a benefit and some additional data collection supported by CMS might provide that additional evidence. While yet to be clearly delineated, there is the potential for this concept to be broadened to the extent that new technologies receive CMS coverage at an earlier time in return for continuous data collection over the life cycle of the technology and a more streamlined process for technologies to enter and leave the CMS coverage toolbox. This concept, somewhat similar to ongoing discussions at FDA, will require significant public discussion and potential legislative action. CMS does have limits in its abilities to influence learning behavior. Its policy options are essentially payment options. We do think there is a leadership role for government; as we implement on a small scale a particular policy that we think will assist in developing more evidence, we think that particular leadership role will trickle down into other settings. In our current healthcare system, physician learning typically comes from training and experience. Patient learning comes from physicians or the Internet—a fairly inaccurate database. Movement toward a system in which both providers and patients are basing decision about their health care on good, reliable information is a challenge. It is a challenge that CMS and HHS are engaged

The Learning Healthcare System: Workshop Summary and reimbursement arenas to generate sufficient financial incentive and drive the change. Technologically, the development process should leverage information from qualified biomarkers, surrogate markers, and development simulations, in concert with regulatory authorities, prior to first patient exposure. Once available to some patients, use of the evolving EHR systems at major payer and academic medical centers can begin a process of continuous data capture and simulation confirmation in broadening patient numbers. At a point agreed between the innovator, regulator, and possibly the payer there is an initial release where the innovator can begin to recoup investment cost in a proscribed patient base while additional data accumulate until there is a full release of the new therapy. This is a very different way of doing drug development, a concept that drug development never stops, or maybe the learning development system. It is not possible for any one stakeholder to solve these issues, and if we are going to make evidence-based medicine work for our healthcare system we all need to work together. This includes the pharmaceutical and biotech industry, provider organizations, government agencies, the diagnostic and device companies, payers, and technology providers. As we work through this new world for health care we need to keep the patient in the middle of our dialogue, which must be about putting patient health first. OPPORTUNITIES FOR STANDARDS ORGANIZATIONS Margaret E. O’Kane National Committee for Quality Assurance Foundational to any exploration of evidence development in health care is a restatement of the central mission of health care: to improve health. In many ways we have moved too far away from this mission and pursued a series of tangential goals that, while important, have led us to lose sight of where we are going. If we are to achieve the mission, healthcare regulators, accreditors, purchasers, consumers, and providers must build their efforts around this larger goal. Today, the healthcare quality movement is being held hostage to ever-rising costs and the failure to manage evidence effectively. Our current payment system is irrational, wasteful, and inequitable by any measure; as a result, healthcare costs are being driven to the boundaries of society’s ability and willingness to pay. Over the last six years, the average cost of health insurance for a family of four Americans has jumped 87 percent, a larger increase than any other sector of our economy (Kaiser Family Foundation 2006). Healthcare costs have eaten into corporate profits and family incomes. Even in 2005, when insurance inflation dropped to 7.7 percent, that
OCR for page 305
The Learning Healthcare System: Workshop Summary increase and the accompanying shift of costs to employees ate up much of the average 3.8 percent rise in Americans’ wages (Kaiser Family Foundation 2006). Until we deal with costs, our efforts to improve quality will always take a back seat. Yet we know that these two issues are intricately entwined. Poor-quality care can cost more than high-quality care. If a patient gets the right care at the right time for the conditions that ail her, there will often be less need for more expensive, high-cost treatment of complications in the future. High-quality care also leads to greater productivity on the job and healthier and happier families at home. Addressing the Evidence Gaps We need to think in terms of populations. If we really think clearly about how health care affects populations, we will all be better off. In their impressive book Epidemic of Care, George Halvorson and George Isham presented us with a visual representation of population-based health that offers a way of thinking about the health of the American public. It reflects the continuum of health of the population of the United States, of a state, of a city, of a community, or even of a health plan. As time goes by, however, some of those people move into “at-risk” or “high- risk” or “early-symptom” categories. This representation has been adapted in Figure 8-1 to illustrate how we need to keep healthy people healthy, and to identify those who are at risk and move them back to the healthy stage through treat- FIGURE 8-1 A value-based healthcare system moves people to the left—and keeps them there.

The Learning Healthcare System: Workshop Summary ment and behavioral modification. As a population moves further toward high risk and active illness, we must give people the appropriate care and support to keep them as healthy as possible. Finally, when people are living with active disease or are at the end of life, we need to help them manage their illness, coordinate their complex care, alleviate their pain, and assist them in dying with dignity. We also know that 80 percent of healthcare dollars are spent on the 20 percent of the population who are in this last stage of health. Sadly, much of that care is of poor quality or unnecessary and neither prolongs nor improves life. If we can reduce the amount of money we spend there—through improved quality in earlier stages and a more rational use of care in the latter stages—not only could we help address our overall cost problems but we could redirect some of that money toward the earlier stages of the continuum that provide a better payback in health for the healthcare dollar. NCQA has adopted this framework to guide our efforts to accredit health plans and measure the performance of healthcare providers. We have developed a paradigm that holds the plan accountable for the quality of care and service provided to its members. The plans, in turn, often hold providers accountable for delivering care that is evidence-based and of high quality. In the health plan accreditation process, NCQA assesses the performance of health plans in three ways. First, we establish standards for structural and procedural activities meant to ensure patients’ rights, appropriate utilization management, quality improvement, customer service, and access to care. Second, we require plans to measure and report on their performance through HEDIS, a set of standardized, evidence-based measures. This unique approach allows us to evaluate how often patients receive the right care at the right time. Finally, we ask patients about their experiences with their health plans and providers. The Consumer Assessment of Health Plans and Providers (CAHPS) examines both a plan’s direct administrative performance and members’ experience with the delivery system. Together, these three parts combine to form an accreditation program that has become a model for public and private oversight of health care. It is the only accreditation program in health care where performance measurement drives a substantial proportion of the scoring. Clearly, when one considers the list of HEDIS measures (Table 8-1), there are many important aspects of care that are being measured. It is important to note that for what we measure, there have been notable gains for patients, purchasers, and the health plans that report. NCQA has documented enormous improvements on the issues that it does measure. For example, the use of beta-blockers has increased substantially over the last decade. Health plans are now reporting 95 percent of patients being discharged from the hospital after a heart attack or major cardiac procedure on a beta-blocker, up from 69 percent in 1996 when NCQA began measur-

Children are nearly three times as likely to have had all their recommended immunizations as they were in 1997. Diabetics are twice as likely to have their cholesterol controlled (< 130 mg/dL) as in 1998. These are just a few examples. We are extremely proud of the ground that we broke here because we know that there are people alive and healthier today because of this improvement (Figure 8-2). This transparency and accountability for quality is something really worth promoting—because we know it works. However, there are also many aspects of care that are not being measured, and this is where we need to focus as we move forward. Despite our progress on accountability, significant barriers remain to robust measurement of performance across the healthcare system. These include the following: The absence of evidence. Despite tremendous growth in funding of biomedical research in the United States and abroad, there are significant gaps in our evidence base. The process of managing the evidence base toward a return on investment in health can

The Learning Healthcare System: Workshop Summary FIGURE 8-2 Selected HEDIS improvements: 1999-2004. only be described as haphazard. Often research is conducted in areas that are already well understood, while areas that may be clinically important remain uncharted. As a result, in many areas, we simply do not know what constitutes effective care. There are many examples, such as the basic science behind effective treatment for esophageal cancer and the appropriate care for patients with multiple conditions. We lack clinical trial data for the elderly. We do not know about the comparative effectiveness of many treatments so that we cannot evaluate how treatment “A” compares to treatments “B” or “C” in terms of risks, outcomes, and costs. David Eddy has mapped the areas of what we know in diabetes and heart care, and he uses the metaphor “islands of knowledge.” We have some islands of knowledge, supported by repetitive and redundant trials, while there remains a vast sea of ignorance that is unexplored. There is a tremendous need to proactively manage the evidence base. The funders of research must make sure that we are being strategic on where we need to develop more evidence. So it isn’t just turning research into practice, it is figuring out where there are basic research gaps. The best way to identify priorities would be to look at issues that affect large numbers of patients with a high cost of disease burden and expense and where practice is not solidly evidence based. Issues could be prioritized using quality-adjusted life years per dollar spent. Finally, evidence-based guidelines for patients with a combination of conditions are

Even where the evidence exists, there is often a failure to convert it into usable guidelines because we have a significant failure to develop consensus about the evidence. Medical specialty societies develop their own guidelines, often producing conflicting guidelines for the same patients, and this creates a lot of confusion. The model of specialty societies developing their own guidelines without some kind of overall organizing structure needs rethinking. For example, orthopedists, neurosurgeons, and internists disagree on when to do surgery for back pain. As a result, there is no cohesion in approaches or agreement on what is appropriate. We also have some guidelines that do not go far enough. For example, the guidelines for screening for depression or cholesterol levels in the general population do not specify the appropriate intervals. Here again, however, the evidence base that could determine the appropriate guideline has not been adequately marshaled to do so. The lack of or difficulty in obtaining data. There are also important barriers to getting the data to assess performance. NCQA had to abandon an otitis media measure because health plans were unable to find the data in patients’ medical charts. This is true in many other areas. The lack of accountability. Appearances to the contrary, only a small part of the current healthcare system is being held accountable through quality measurement and reporting. Among health plans, only health maintenance organizations (HMOs) and point of service (POS) plans are called on to report HEDIS. Yet those plans account for only a third of all Americans enrolled in private health plans. Only a handful of preferred provider organizations (PPOs), which cover 64 percent of privately insured Americans, collect and report HEDIS (National Committee for Quality Assurance 2006). Another significant barrier is the relative absence of performance measurement at the provider level. Some progress has been made in recent years in developing and implementing hospital focused measures. The Joint Commission on Accreditation of Healthcare Organizations, the Leapfrog Group, and the Hospital Quality Alliance have each developed measures that are now in broad use. There has been less progress on the physician side of the ledger. NCQA, working with the American Medical Association and its Physician Consortium for Performance Improvement, has developed physician-level HEDIS measures for certain conditions and has been working in partnership with CMS) to develop additional measures at the

The Learning Healthcare System: Workshop Summary specialty level. Much more work needs to be done before we are even close to a system of physician-level accountability. NCQA has developed a set of programs designed to recognize high-performing physicians in diabetes and heart or stroke care, as well as practices that utilize clinical information systems to improve care across the board. These recognition programs also form the basis for several pay for performance initiatives operating around the United States, including the Bridges to Excellence program sponsored by large employers and the Integrated Healthcare Association program in California that works with large medical groups. NCQA also has been working with a variety of partners to develop a new CAHPS survey for clinician groups. Measuring at the physician level presents other challenges as well. When it comes to individual doctors, we have a limited, insufficient sample size to assess performance. Yet more than half of American doctors practice in one- or two-member practices. Except for some proceduralists, individual physicians simply do not treat enough patients with a particular condition to draw valid conclusions. We need to recognize these limitations and factor them into our planning and implementation in order to safeguard the integrity of the measurement process. The advent of electronic health records will help decrease the burden and expense of data collection—but only if we get the right kind of EHRs. The current generation of EHRs leaves much to be desired in terms of their usefulness to improve quality. Partly, this is because processes in health care are often unique to the practice microenvironment and, to some extent, standardized software requires standardized process. Perhaps the biggest potential for EHRs is their theoretical ability to provide customized reminders and warnings for each patient based on specific medical history, diagnoses, and situations. Comprehensive EHRs can also support appropriate decision making, but the current generation of products generally does not have these capabilities. In fact, many current EHRs don’t even have the capability of producing performance data after the fact. How Can We Advance? If we are to achieve a system that is truly accountable for quality, we must overcome the politics, the warring measures, resource use-cost measures, and political opposition that stand in the way of comprehensive quality assessment. We also need to address issues of appropriateness. Another problem that must be addressed is unclear accountabilities. There needs to be some entity or organization larger than the individual provider that is ultimately responsible for coordinating care across boundaries and practice settings and taking responsibility for at-risk patients after discharge. Once again, the sickest 20 percent of patients account for 80 percent of medical

The Learning Healthcare System: Workshop Summary BOX 8-1 Comprehensive evidence management will do the following: Identify the gaps Encourage priority research areas Promote paradigms of continuous learning and evidence development Gather patient reported impact/outcomes Consider patient preferences costs and there are important opportunities to improve quality and reduce costs with this group. As we attempt to move practice toward a stronger evidence base, it is crucial that we chart an approach to comprehensive evidence management in order to exercise responsible stewardship for scarce healthcare resources. This will require cooperation across stakeholder groups and specialty and disease organizations, as well as substantial public funding. We need a comprehensive function of evidence management (Box 8-1). This enterprise would identify the gaps, encourage priority research areas, and promote paradigms of continuous learning and evidence development. In order to have the greatest impact, consider the establishment of an evidence stewardship board to do three things: (1) evaluate the current medical evidence and publish guidelines; (2) identify priority areas for new evidence development; and (3) consider ways to move beyond clinical trials in an era when much more real-time information can be gleaned from practice and used to study what works. Such a board would be analogous to the U.S. Preventive Services Task Force, but covering the broad scope of medical practice. There are four basic policy enablers and each must play a role to drive systematic improvements in health care (Box 8-2). First, we must change the way that we pay for health care in this country. Payment reforms such as pay for performance, and other current models, are a good beginning, but they are generally based on fee-for-service payment. With new technology we all know that the old models of care, even some team-based care, are hopelessly inefficient. We must stop providing financial rewards for what we know is inefficient and ineffective medicine. The move to Diagnosis-Related Groups (DRGs) in the early1980s and the Resource-Based Relative Value Scale (RBRVS) in the early 1990s were significant advances, moving us away from true fee-for-service toward a system that is based more on the average cost of performing a group of

The Learning Healthcare System: Workshop Summary BOX 8-2 Policy Enablers Needed: Payment reform Regulatory reform Liability reform Patient Activation services. It is time for a new generation of payment reform that utilizes bundled payments with strong incentives for efficient delivery of high-quality care. This kind of payment demands true quality transparency at the same time. Second, we need regulatory reform. The role of policy makers is to encourage promising new models of care; figure out which ones are taking us toward higher-quality, affordable health care; and then push relentlessly to make the whole delivery system move in that direction. Old and outmoded regulatory requirements need to be dropped as new and more powerful techniques are adopted. Third, liability reform is also part of the change management process. The current litigious environment is an impediment to good medicine, which requires a special partnership between patients and their healthcare providers. We need to make a new deal with society. We need to modify our practices going forward, and in return, we ask that we have some protection as we seek to improve the delivery system. Finally, we need real patient activation. It is critical that we recognize that patient-centered health care requires that we do more than make data available or even provide it to patients and expect them to do the right thing. A very important area that needs to be more fully explored is determining the best ways to motivate patients. We need to take a comprehensive look at how both providers and the health system as a whole can help people make healthier choices, without creating dependency or increasing costs. We need to address issues such as health literacy and the need for culturally and linguistically appropriate services in order to communicate with patients in a manner that they understand and that motivates them to make lifestyle changes to improve their health and play an active role in managing their conditions. At the end of the day, our purpose in quality measurement is not to derive knowledge in order to deliver it back into the same process. We will only maximize the benefits of performance measurement by addressing the structural elements that must be in place for systemic improvement.

The Learning Healthcare System: Workshop Summary We need to find different ways to gather information in the first place; then transformation becomes not only desirable but almost unavoidable. As we explore new models for knowledge development, there are important considerations for how to effectively use them. Also very importantly, regulators, accreditors, and certifiers must work hard to evolve their approaches to accountability to support and encourage and not stifle knowledge development. Old paradigms based on assumed relationships between structure and outcomes need to be either justified or replaced with more evidence-based constructs if regulators, accreditors, and certifiers are to be drivers and enablers of progress rather than impediments to it.
