Introduction

Current challenges faced by the medical sector call for a dramatic shift in how professionals across the United States deliver health care. Primary Care Medical Home (PCMH)models provide physicians with excellent opportunities toco-create competent portals to health care that are positive and beneficial for both patients and physicians. Our nation’s current health care system works well for neither physicians nor consumers. By returning to the “home” of health care, doctors can begin truly caring for and forging mutually supportive relationships with their patients.

Consumers need change

There is a quality chasm in health care. Although Americans have been paying more and the American government has been investing more, we discuss here that their spending has not yielded better quality of care or improved health out-comes.

An Overview–What the U.S. spends on healthcare

  • $2.5 trillion (or 17.6% of the nation’s Gross DomesticProduct [GDP]) will have been spent on health care in theUnited States by the end of 2009
  • $4 trillion (or nearly 20% of its GDP) will have been spent on health care by the end of 2015
  • In 2006, the United States ranked highest in per-capita spending on health care among Organization for Economic Cooperation and Development (OECD) member nations—spending 48%more than Norway, which was ranked third highest

In the United States, there is no link between higherhealth care costs and levels of quality or safety (Fig. 1):

  • 98,000 to 195,000 people die annually, in the United States because of medical errors

  • 57,000+ die annually as a result of receiving inadequate care

  • Two million hospital-acquired infections cause 90,000 deaths each year

  • Americans pay four times more than those who receive similar quality of care elsewhere around the world

  • The United States’ health system was ranked 37th in overall performance by the World Health Organization (WHO) in its World Health Report 2000.

  • Among all 30 OECD member nations, the United States ranked 22nd in terms of life expectancy, 28th for its efforts to stave off infant mortality, and 30th (or last) in its success at controlling obesity1

    The increasing prevalence of chronic diseases among members of the US population is, by itself, sufficient mo- tivation to change the structure of the nation’s current health care system. Studies that have tracked the quality of health care services reflect—across the board—a lack of effi- ciency. Uncoordinated care cost patients and health care providers dearly and adds greatly to the financial burdens of patients and care facilities alike. Peter Orszag, director of the Congressional Budget Office, estimates that 5% of the nation’s GDP, or $700 billion per year, is spent on tests and procedures that do not actually improve health outcomes (Fig. 2).2


    ‌Physicians need change

    Results of an October 2008 survey of US physicians who were asked to assess their profession paint a grim picture. For example, a majority of currently practicing physician respondents stated that they would not recommend medi- cine as a career, and a majority of allopathic medical stu- dents responded that they are choosing not to become pri- mary care doctors. Efficiency in US primary care settings is not being rewarded, and broad gaps exist among payments made to primary care providers and those issued to providers of subspecialty care. Medicare’s physician payment methods focus on chronic disease care rather than patient education— the kind of preventive measures that help divert the need for such care. Such payment methods support neither patient education nor efforts toward improving coordinated care but are instead offered in support of episodic care and capita- tion.3

    A survey issued to 161 attending physicians and 101 residents practicing at a large urban teaching hospital and an additional 21 suburban primary care practices found that:

  • 100% of respondents believed it was important to notify patients of abnormal results

  • 36% said they did not always follow through with noti- fication

  • 72% said they do not notify patients if results are normal

  • 77% said there was no reliable method for tracking whether patients with abnormal test results had received recommended follow-up care

  • 97% did not know whether patients took their prescribed medications4-7


    Background on PCMH

    The use of the term medical home spans across four decades and was first used by the American Academy of Pediatrics (AAP) in 1967. MassGeneral Hospital for Children (MGHfC) has defined a medical home as a facility for “primary care that is accessible, continuous, comprehensive, family centered, coordinated, compassionate, and cul- turally effective.” WHO (1978) has embraced the term since its inception and the Institute of Medicine (IOM) provided the tenets that established a framework for defining the concept of the PCMH in 2007 when it held a consortium of several leading organizations—including the American Os- teopathic Association (AOA), the American Academy of Family Practice (AAFP), the American Academy of Pedi- atrics (AAP), and the American College of Physicians (ACP).8 The consortium also sought to promote aspects of the Chronic Care Model, which have been shown to en- hance cost effectiveness in providing patient care and im- prove quality of care as a mechanism for improving primary care delivery.


    PCMH core features

    The PCMH model possesses several attractive core features that appeal to both patients and physicians. Although seem- ingly simple, the establishment of these core features has shown just what PCMH can contribute to the current US health care landscape.9-11 They call on physicians to unite with one another, with their associations, and with their government leaders in an effort to shake up the health care system status quo.

    PCMH core features include the following:

  • Enhanced Access—Enhanced access encourages im- proved communication between patients and health care delivery systems

  • Payment Reform—Payment reform practices are de- signed to reduce waste and inefficiency while enhancing patient-centered care and promoting accountability

  • Personal Physicians—One “personal” physician oversees the care provided by all others involved in the process to encourage collaboration and teamwork

  • Physician-Directed Medical Practice—The personal phy- sician leads a team (at the practice level) that collectively takes responsibility for the ongoing care of patients

  • Quality and Safety—Physicians engage in performance measures that promote continual improvement and ac- countability

  • Whole-Person Orientation—A whole-person approach is adopted to tackle issues dealing with mind and body; integrated care blends family and health care services to meet varying cultural and linguistic needs


    Evidence that PCMH works

    PCMH models provide physicians with excellent opportu- nities to co-create competent portals to health care. In 2008, the Patient-Centered Primary Care Collaborative (PCPCC) compiled a report that summarized research conducted on ongoing, nationwide efforts evidencing that PCMH adop- tion leads to cost savings, better health outcomes, and higher levels of patient satisfaction. The PCPCC ultimately found that care delivered by primary care physicians work- ing within a PCMH framework was consistently associated with better outcomes: Reductions in preventable hospital admissions for patients with chronic diseases, reduced mor- tality rates, reduced utilization rates, increased patient com- pliance rates, and reduced medical expenses.12,13

    In an article entitled “Contribution of Primary Care to Health Systems and Health,” Starfield et al.14 detailed the role primary care has played in influencing health promo- tion. Other publications have also outlined the vital function primary care plays in promoting the equitable distribution of health and the prevention of illness and death.15 The med- ical home concept posits that a primary care physician’s direct and trusted relationship with patients, when coupled with deep and broad clinical training across body systems, positions them to assess individuals’ health care needs and tailor comprehensive approaches to care across conditions, care settings, and providers.16

    A strong starting point for reducing US health care ex- penses overall is the implementation of a long-term strategy that reduces the costs associated with unmanaged chronic conditions. As RAND and Dartmouth researchers have doc- umented, the return on that investment is potentially signif- icant— enough to fund expansion of insurance coverage (thereby increasing access) and reducing the demand for specialty care and acute services (thereby reducing costs). Unfortunately, incentives to arrest the progression of chronic disease do not exist within today’s health care system. In fact, that very system rewards acute episodic care, whereas proactive care, care management, active in- tegrated interspecialty management, and a number of pre- ventive care services go unreimbursed.17

    “We have made major improvements in prevention . . . but it’s difficult,” Dr. Gregg W. Stone, Director Cardiovas- cular Research at Columbia University, has said. “It takes frequent visits, a close relationship between a physician and a patient and a very committed patient.”18 He and other cardiologists believe that with access to the right form of preventive care, patients could reduce their risk of heart attack by as much as 80%.


    National demonstration project results

    To date, more than 30 PCMH pilot programs have been launched. Many, such as those described next, have dem- onstrated improvements in the areas of health care cost, quality, and access.

Chronic conditions and the PCMH model

A major contributor to escalating health care costs is the growing prevalence of chronic conditions that now affect every subgroup of the population—from children to the elderly.

According to reports published by the Center for Eval- uative Clinical Sciences at Dartmouth20 (serving patients with severe chronic diseases), Americans who live in states that rely heavily on primary care experience lower Medicare spending (because of inpatient reimbursements and Part B payment), lower resource inputs (hospital beds, intensive care unit [ICU] beds, total physician labor, primary care labor, and medical specialist labor), lower utilization rates (physician visits, days in ICU, days in the hospital, and fewer patients seeing 10 or more physicians), and better quality of care (fewer ICU deaths and a high composite quality score) (Table 1).

The Commonwealth Fund found that when adults had access to a medical home model, their access to needed care, receipt of routine preventive screenings, and manage- ment of chronic conditions improved substantially.21 The Fund also reported that when primary care physicians work- ing within the United States effectively managed care in the office setting, patients with chronic disease (such as diabe- tes, obesity, congestive heart failure, and adult asthma) suffered fewer complications and experienced a reduction in avoidable hospitalizations (Fig. 3).22

‌Obesity‌

Obesity is one of the most prevalent chronic conditions facing the United States, where 31% of the population is considered obese. It is a leading cause of morbidity and mortality; one that is associated with high medical expen- diture and an increased risk for the development of diseases that are in turn responsible for the rising costs of health care, as documented in the 2000 Medical Expenditures Panel Survey.23

Obesity, as a chronic condition, is an ideal target for PCMH practice, because it is widespread enough to dem- onstrate impact, the data associated with obesity is easily tracked, and large cost-savings potentials exist. Obese patients often suffer from a variety of disorders and may have compliance issues, and they are at risk for many other diseases. Also there are well established standardscof care that already exist to help manage and maintain routine care.

Orlando Smith, one of the first patients to participate in Metro Health’s Lee-Harvard Health Center in Cleveland PCMH program, has credited the model with helping him in his struggle against diabetes and its associated risks. Regarding the new program that helped him lose weight and lower his cholesterol, Smith said, “You know when somebody is treating you with dignity.” A care coordinator at the Center managed Smith’s appointments, made sure he saw the same doctor every time he came in for a visit, and signed him up for a related class in proper nutrition.24 Smith’s story has helped illustrate one of the key points behind the PCMH concept, one that calls for meaningful change in the daily habits of a pop- ulation plagued by chronic disease. To affect this change, primary care physicians have been asked to lead teams of coaches (which are comprised of nurses, pharmacists, nutri- tionists, and other medical professionals), with the goal of providing a more ”holistic” approach to health care.25 “Even- tually, a healthier population would reduce the number of medical procedures and costly hospital admissions—poten- tially lowering consumers’ insurance premiums,” IBM Direc- tor of Health Care, Technology and Strategic Initiatives Dr. Paul Grundy has said. “We have seen, in PCMH pilots, that if we focus on prevention, we really begin to see results.”25

To that end, a research team from RAND (in partnership with the University of California at Berkley) undertook a rigorous evaluation of care provided according to PCMH principles. After evaluating nearly 4000 patients with dia- betes, obesity, congestive heart failure, asthma, and depres- sion, they found that patients with diabetes experienced significant reductions in cardiovascular risk, that congestive heart failure patients reduced their hospital days by 35%, and that asthma and diabetes patients were more likely to receive appropriate therapies.26

‌Conclusion‌

A significant transformation of the US health care system appears to be imminent and will include investments in the prevention of chronic care diseases as a basis of primary care and the PCMH model. Medical homes can be created now as part of that transformation. Existing research cited here and elsewhere has demonstrated that care delivered by primary care physicians working within PCMH parameters is consistently associated with better outcomes, reduced mortality rates, and fewer preventable hospital admissions for patients with chronic diseases.In an article entitled “A House is Not a Home: KeepingPatients at the Center of Practice Redesign,” Robert Berenson stated that the PCMH model is a promising approach to vhronic care that awaits more data. Berenson questions whether PCMH’s central tenet is to avoid expense in chronic illness and asks how the savings compare to the status quo. To date, no one knows. Although a generalizable, cost-effectiveness study on initiatives incorporating all of the PCMH’s elements does not yet exist,27it is certainly an area that is worthy of future research.28But change, it would seem, is still required
