The federal government's $20 billion stimulus programs for health IT (HIT) is on its way. Called HITECH—for Health Information Technology for Economic and Clinical Health Act—it will fund the development of innovative HIT and use a "carrot & stick" financial approach to encourage clinicians to use HIT in meaningful ways. A debate now raging is how to define "meaningful use."
Meaningful use, to me, means using HIT in ways that are of great value to the patient and other healthcare consumers. It doesn't matter what types of software tools are used, what communication infrastructure is used, what standards are used, or what certifications are used. It just means that the using HIT should result in ever more effective and efficient (i.e., ever greater value) care delivery.
Increasing care value is unlikely unless clinicians obtain information and guidance assisting them in answering difficult questions, making tough diagnostic and treatment decisions, collaborating effectively, and taking competent action. In addition, healthcare consumers (patients, clients, customers, etc.) would benefit from assistance in selecting the most cost-effective treatment options for existing conditions, and in managing their own health in ways that prevent illness, control chronic conditions, and increase their well-being.
Such assistance is crucial because the unaided human mind simply cannot handle the overwhelming details and complexity of many health problems. Consider the following section which contains important quotes from Dr. Larry Weed and others:
The volume of clinical information expands exponentially with more than 150,000 medical articles published each month in more than 20,000 biomedical journals. Healthcare providers struggle to stay current with the clinical information, but inevitably become overloaded. This may contribute to the slow adoption of evidence-based research in clinical practice. There is just too much clinical information being generated for providers to incorporate into their internal base of knowledge.
As a group, healthcare providers care about patients and take pride in doing an excellent job in caring for their well-being. Nevertheless, the "…task of knowing every detail is way beyond the [ability of] human mind… For example…diabetes care ought to take into account any of 120 management options and 380 possible patient conditions associated with the disease. …the unaided mind cannot reliably recall all the causes or management options that should be considered for each patient, nor can it recall all the findings in the patient needed to discriminate among those options, nor can it reliably match findings to options under the time constraints of practice."
In addition, "…most physicians are able to take into account only a portion of the diagnostic and management options potentially relevant to their patients and only a fraction of the evidence needed for choosing among those options. …Physicians do little better with the usual aids to medical decision making, such as practice guidelines and use of Internet resources. Those aids provide general knowledge, but do not ensure that the physician will recall all the data or successfully link it with a particular patient's specific problem." Problems that cross specialty boundaries and require multiple specialists, yet the current healthcare system does a poor job at supporting communication between providers and assuring continuity of care. And primary care physicians are not equipped with the information tools necessary to grapple with the information overload, nor do they have a system for coordinated care within which to function.
"Because physician time is expensive and scarce, their initial workups can be meager [as they] …act according to their own preconceived notions about what history, physical, and laboratory findings are worth checking. Equally idiosyncratic are the conclusions they draw from whatever data they select. Both selection and analysis of data are influenced heavily by their medical education, prior clinical experience, specialty orientation, contradictory clinical guidelines, financial concerns, cultural background, personal biases, and day-to-day time constraints, all of which vary enormously among individual practitioners."With this in mind, consider the recent report by the National Research Council of the National Academies, which concluded that a serious gap in health information technology (HIT) today is the failure to deliver patient-centered cognitive support (also called consumer-centered cognitive support). According to the report:
During the committee's discussions, patient-centered cognitive support emerged as an overarching grand research challenge to focus health-related efforts of the computer science research community, which can play an important role in helping to cross the health care IT chasm...Today, clinicians spend a great deal of time and energy searching and sifting through raw data about patients and trying to integrate the data with their general medical knowledge to form relevant mental abstractions and associations relevant to the patient's situation…The health care IT systems of today tend not to provide assistance with this sifting task…[We need] computer-based tools [that] examine raw data relevant to a specific patient and suggest their clinical implications given the context of the models and abstractions. Computers can then provide decision support—that is, tools that help clinicians decide on a course of action in response to an understanding of the patient's status. At any time, clinicians have the ability to access the raw data as needed if they wish to explore the presented interpretations and abstractions in greater depth…The decision support systems would explicitly incorporate patient utilities, values, and resource constraints…They would support holistic plans and would allow users to simulate interventions on the virtual patient before doing them for real.It's logical to conclude from the information above that patient-centered cognitive support is the kind of value-enhancing assistance needed, but largely missing from, today's HIT.
Thus, "meaningful use of HIT" can be translated into "using HIT to increase care value (efficiency and effectiveness) by providing ever-better patient-centered cognitive support."
The HIT Gap and How to Fill it
Is it reasonable to expect the healthcare industry to fill the patient-centered cognitive support gap? According to a recent report by the Congressional Budget Office titled, Evidence on the Costs and Benefits of Health Information Technology, HIT systems have the potential to provide such cognitive support by, for example, reminding physicians to schedule tests, helping them diagnose complicated conditions, assisting them in implementing appropriate treatment protocols, and promoting research focused on developing and evolving evidence-based guidelines.
A Different Definition from HIMSS
While I proposed a path of radical HIT innovation, the Healthcare Information and Management Systems Society (HIMSS) Board of Directors recently proposed a more conventional path, which includes these seven HIT requirements:
- EHR certification by the Certification Commission for Healthcare Information Technology (CCHIT)
- Standardized patient data conforming to the Healthcare Information Technology Standards Panel's (HITSP)
- Interoperability specifications based on the Integrating the Healthcare Enterprise's (IHE) frameworks
- Use of an EHR including CPOE (computerized practitioner order entry) functionality
- Electronic exchange of patient summary information as specified in the Continuity of Care Document (CCD) standard
- Support for a subset of existing National Quality Forum-endorsed process and care measurement
- Use of clinical decision support (CDS) systems providing clinicians with clinical knowledge and intelligently-filtered patient information to enhance patient care.
Item #1 refers to an expensive certification process that stifles radical innovation by forcing out small HIT companies, including open source developers. I can see the benefit of testing HIT vendors product to see how good they work (like Consumer Reports does with cars and appliances), but vendors shouldn't have to pay for it (Consumer Reports doesn't make the manufacturers pay). Instead, a government agency (FDA?) could probably do it. Furthermore, the certification process to which HIMSS refers has nothing to do with patient-centered cognitive support.
Items #2 & 3, which refer to data and technology standards, present a double-edged sword for reasons I discuss in a series of posts starting at http://curinghealthcare.blogspot.com/2007/05/art-of-health-knowledge-creation-use.html. Rather than limiting HIT developers to a specific set of global standards, it would be better to allow them to use local data standards and any technology standards, as long as their tool can exchange required information with tools other vendors develop. That's because well-designed innovative HIT tools should be able to provide patient-centered cognitive support without the constraints of particular data and technology standards.
Items #4 & 5 refer to particular types of HIT, which I agree are important. The problem with making exiting EHRs, CPOEs, and CCDs a requirement for "meaningful use" is (a) the current crop of HIT provides little, if any, patient-centered cognitive support and (b) this constraint may hamper innovation by impeding the invention of alternate types of HIT able to provide superior cognitive support.
HIT is used meaningfully if it focuses on increasing care value (efficiency and effectiveness) to patients and other healthcare consumers by providing ever-better cognitive support. The smart path to meaningful HIT use is one that promotes the kinds of radical innovation that enable widespread collaboration and the application of good science focused on providing continually evolving patient-centered cognitive support. Following this path means (a) accepting that the unaided human mind, no matter how competent, simply cannot handle the incredible amount of complex information that must be processed to make wise decisions in difficult situations, (b) doing more to link scientific research and clinical practice, and (c) encouraging truly creative HIT solutions.

Steve, I believe you are on the right track. The meaningful use of HIT is what? Might I suggest the following: Information of great value easily adapted to a new experience for a specific purpose. So, let’s apply it to the clinical encounter or imagine looking up health information on the web by a patient with a specific set of symptoms. What do you think is more meaningful? Going to the doctor’s office with a set of symptoms or surfing the web for information relevant to the patient’s particular need using the symptoms in a browser window, where the results are presented by relevance. Might I suggest that the latter promotes meaningful use? The latter has more utility, it is easier to obtain and cheaper to access, and the information can be assimilated readily by the patient. Hence, the information received by the patient via the web is meaningful and readily useful because the patient can apply the information for a specific purpose. Until we achieve a higher level of sophistication at the point of care, your cognitive model, i.e., obtaining information that has meaningful use at the doctors office will not occur because the PCP at the point of care has no CPT code to enable reimbursement.
In your example of meaningful use, Sab, you describe a form of cognitive support given to a patient. And you’re right, if such cognitive support requires actions to taken by the patient’s healthcare professional, it will not be delivered very often unless the practitioner gets reimbursed for the extra time and effort. Lacking a procedure code means insurance will not pay. The solution: Expanding the CPT codes to include the delivery of cognitive support for the patient.
