The Obama administration and Congress have clearly stated that their priority for healthcare reform is to expand access to care for uninsured Americans.

If they succeed, an additional 15% of the population will receive healthcare coverage, which will surely increase the demand for treatment. Policy initiatives should ensure that patients will have access to the doctors who are best equipped to provide treatment.

Instead, the government has made clear its intention to prioritize prevention over treatment.

Some members of Congress and the Medicare Payment Advisory Commission (MedPAC) have recommended cutting the pay of specialists to fund an increase in reimbursement for primary care physicians.1, 2 This is necessary, they state, to fund the promotion of preventive care in a "budget neutral" fashion. Prevention and wellness are laudable goals; however, the benefits of prevention will be realized only in the long term. For those who need treatment now, prevention is not a solution.

Of particular concern are the most debilitating conditions that often require specialist intervention. Among these, bone and joint disorders stand out as the leading reason why patients visit doctors3, and the leading cause of disability in the United States, affecting 107 million citizens4 and draining approximately $340 billion per year in lost productivity.5

Disturbingly. the government is convinced that specialists are over-paid, and drive up the cost of healthcare with no corresponding improvement in outcomes.6 This conviction is driving healthcare policy recommendations that could affect patients' access to orthopedic surgeons and other specialists. The premises behind these policy recommendations demand scrutiny.

Premise #1: The U.S. has too many specialists and too few primary care physicians

In fact, the U.S. supply of specialists per capita is 18% below the average of countries in the Organization of Economic Co-operation and Development (OECD).7 Conversely, the U.S. has 20% more primary care physicians per capita than the OECD average.7

Country GPs/1000 Specialists/1000
Netherlands 0.5 0.9
Canada 1 1.1
US 1 1.4
Finland 0.7 1.4
UK 0.7 1.6
France 1.6 1.7
Luxembourg 0.7 1.7
OECD average 0.8 1.7
Australia 1.4 2
Iceland 0.8 2
Denmark 0.8 2.3
Hungary 0.7 2.3
Germany 1 2.4
Switzerland 0.5 2.5
Czech Republic 0.7 2.8

 

Further, the supply of primary care physicians per capita grew 12% from 1995-2005, while the supply of specialists grew only 5%.8

The growth of the supply of orthopedic surgeons lags behind that of primary care physicians and other specialists. While the government projects that the supply of orthopedic surgeons must grow 23-54% in order to meet the growing demand for care, the supply is only expected to grow 3%.9

Premise #2: U.S. specialists are paid too much in comparison to primary care physicians

Despite the concerns of some policymakers that specialists are overpaid compared to primary care physicians,1,2,10 the U.S. is not out of line with other countries in its pay ratios.

Finland 1.4
UK 1.3
Switzerland 1.1
Iceland 1
Czech Republic 0.8

 

Further, primary care physicians have enjoyed larger increases in collections as compared to specialist physicians. From 2004-2008, median collections for primary care physicians increased 15%, while specialists' median collections decreased 4%.11 From 1992-2007, Medicare reimbursement for the top 25 orthopedic procedures decreased 28%.12

Premise #3: Specialists overutilize services to boost income

The government has made it clear that "controlling volume" and "overutilization" are major concerns.6 The Congressional Budget Office asserted in 2008 that the fee-for-service payment method "creates an incentive to provide "additional or more expensive services."35 The premise is that specialists will maximize volume to the extent possible.

In the U.S., however, musculoskeletal treatments are hardly overutilized. The table below shows that the U.S rate of inpatient hospital discharges for musculoskeletal disorders is below the average of OECD countries.13

Could this relatively lower rate be related to lower disease prevalence? A report by McKinsey Global Institute showed that the U.S. has 14% less prevalence of osteoarthritis and joint disorders than its "peer group" (UK, Italy, Germany, Spain, France) and 9% fewer back problems.14 Thus, it's reasonable to assume that the U.S. inpatient discharge rate for musculoskeletal disorders would be 9-14% lower than that of its peer group. In fact, it's 30% lower.13 This is surprising given the greater waiting times for inpatient procedures in OECD countries.34

The OECD database does not segregate outpatient procedures, which may change the relationship somewhat. In the U.S., an estimated 54% of spine and joint procedures are performed in an outpatient setting33, while in OECD countries outpatient procedures consume 52% of healthcare expenditures.14

Thus, it is hard to argue that the U.S. overutilizes musculoskeletal services. Indeed, in certain orthopedic sub-specialties, evidence indicates that the number of patients who need orthopedic care far exceeds those who actually receive it.15, 16

Utilization decisions are best left to one surgeon and one patient, determining the appropriate treatment in each situation. The consequences of the government miscalculating are severe, including reduced access for patients in need, and ultimately higher costs as treatment is deferred or forgone entirely.

Premise #4: Specialists do not deliver better quality and patient satisfaction

In its June, 2008 report, MedPAC stated:

"Research suggests that reducing reliance on specialty care may improve the efficiency and quality of health care delivery. Areas with higher rates of specialty care per person are associated with higher spending but not improved access, quality, health outcomes, or patient satisfaction."6

The research cited by MedPAC generally concludes that geographies with high concentrations of specialists relative to primary care physicians were characterized by higher Medicare spending and lower quality. Healthcare reformers should exercise caution when basing policy design on this research, for the following reasons:

  • The research generally did not look at the value of individual specialties in treating discrete conditions, where specialists appear to provide better care. Indeed, one published literature review found that the vast majority of studies which compared outcomes for a discrete condition reported superior results from specialty care as compared to generalist care, while noting the limitations of the available research and methodology.17 In an extensive review of literature on the knowledge and outcomes of generalists and specialists, Harrold, et al., reported that "specialists were generally more knowledgeable about their area of expertise and quicker to adopt new and effective treatments than generalists."18

  • MedPAC does not cite, or perhaps dismissed, contrary research that shows that more specialists result in higher quality. Cooper reports that quality is highest in areas with the greatest concentration of specialists and primary care physicians.19

The academic literature on the relationship between the regional supply of physicians, cost and "quality" is extensive, and consistently shows that the high concentration of primary care physicians correlates positively with lower rates of utilization, spending, and mortality.20 This is no surprise; better access to primary care physicians should indeed result in better health.

But does that mean we need fewer specialists to provide treatment for complex disorders? We may indeed have an excess of some types of specialists. In the case of orthopedic surgery, however, evidence indicates underutilization and a future shortage of surgeons.

Premise #5: More primary care physicians will improve the coordination of care

Coordination of care has been shown to improve outcomes and satisfaction, in orthopedics and for surgical patients in general.21, 22 However, the government's view of coordination appears to be decidedly one-way, i.e., pay primary care physicians to coordinate care, at the expense of the providers of specialty care.

Well-educated primary care physicians can facilitate access. Too often, however, this is not the case. For example, Schoenberg, et al., report that only 25% of primary care physicians discussed joint replacement surgery as an option with Medicare-age patients with severe osteoarthritis.23 Further, 83% of primary care physicians underestimated the success rate of total joint arthroplasty.24 Lynch, et al., found that a majority of academic primary care providers "failed to demonstrate adequate musculoskeletal knowledge and confidence."25

Simply paying primary care physicians to coordinate care does not guarantee better outcomes for orthopedic patients. Primary care physicians must also improve their understanding of the value of specialty orthopedic care and refer patients in a timely fashion.

Premise #6: More primary care physicians will result in prevention of disease

While prevention of disease and disorders is certainly a worthy objective, the opportunities to prevent musculoskeletal disorders are limited. The U.S. Preventive Services Task Force (USPSTF) lists only two statements on the prevention of musculoskeletal disorders; one for low back and one for osteoporosis. It recommends regular screening for osteoporosis, but finds no evidence to recommend preventive interventions for low back pain.26 Certainly, reducing obesity may help reduce the burden of musculoskeletal disorders. However it remains an open question whether increasing the supply of primary care physicians and reducing the supply of specialists will reduce obesity among U.S. citizens, particularly when primary care physicians have found obesity treatment to be less effective than treatment of other chronic conditions.27

The government views prevention as strictly the province of primary care physicians. Yet orthopedic care has tremendous preventive value, restoring motion and forestalling the deleterious impact of a sedentary lifestyle. Indeed, chronic conditions are significantly more prevalent among adults with arthritis than among the general population.28 For example, physical inactivity was significantly higher among patients with arthritis and diabetes than among those with diabetes alone.29

Orthopedic surgery can also help patients improve their cardiovascular health. Arthritis and heart disease frequently co-exist; 57.8% of adults with heart disease also suffer from arthritis.30 Patients who receive total hip and knee replacements improve their cardiovascular fitness, while untreated patients show continued deterioration.31,32 If arthritis and other musculoskeletal disorders restrict patients' movement, it stands to reason that prevention of chronic disease, and the effectiveness of therapies required to control existing chronic disease, become significantly more difficult.

Conclusion: Bad premises lead to bad policy

Healthcare reformers are correct to pursue greater coordination and prevention, and to reward primary care physicians appropriately. However, Medicare must recognize that its first priority is to treat sick and injured people, especially given the short-term need to address the impending increase in Medicare beneficiaries. Reformers must ensure that they do not use flawed premises to create policies that restrict patient access to skilled specialists.

Both primary care physicians and specialists practice care coordination and preventive medicine. Indeed, orthopedic care has great preventive value, and orthopedic surgical intervention is highly cost-effective. Rational reimbursement reform cannot emerge from an oversimplified view that ignores the relative value of treatments, and the tremendous economic value of orthopedic care in particular.
