More Americans Willing to Limit Physician-Hospital Choice for Lower Medical Costs

Issue Brief No. 94
March 2005
Ha T. Tu

More Americans are willing to limit their choice of physicians and hospitals to save on out-of-pocket medical costs, according to a new national study by the Center for Studying Health System Change (HSC). Between 2001 and 2003, the proportion of working-age Americans with employer coverage willing to trade broad choice of providers for lower costs increased from 55 percent to 59 percent—after the rate had been stable since 1997. While low-income consumers were most willing to give up provider choice in return for lower costs, even higher-income Americans reported a significant increase in willingness to limit choice. Compared with other adults, people with chronic conditions were only slightly less willing to limit their choice of physicians and hospitals to save on costs. Perhaps as a result of growing out-of-pocket medical expenses in recent years, the proportion of people with chronic conditions willing to trade provider choice for lower costs rose substantially from 51 percent in 2001 to 56 percent in 2003.


Lower Costs vs. Unfettered Choice of Physicians and Hospitals

he proportion of working-age Americans willing to limit their choice of health care providers to save on out-of-pocket medical costs grew significantly between 2001 and 2003, according to HSC’s Community Tracking Study (CTS) Household Survey (see Data Source). In 2003, 59 percent of adults 18 to 64 years old covered by employer-sponsored insurance, or 61 million people, agreed with the statement: “I would be willing to accept a limited choice of physicians and hospitals if I could save money on my out-of-pocket costs for health care” (see Figure 1). In 2001, 55 percent of working-age adults with employer coverage (58 million) were willing to make this trade-off.

Consumer demand for broader choice of health care providers was a driving force behind the managed care backlash of the mid-1990s. Under pressure from employers and consumers, health plans broadened provider networks and eased other care restrictions, but these changes were accompanied by rapidly rising health insurance premiums. Responding to rapidly rising premiums, many employers in 2002 began increasing patient cost sharing through higher deductibles, copayments and coinsurance. 1

Consumer choice-cost preferences were quite stable through 2001, making the change from 2001 to 2003 all the more notable (see Supplementary Table 1). A likely explanation for the change in consumer attitudes is that the growing burden of out-of-pocket medical costs is prompting a reassessment of the choice-cost trade-off.

Income Matters

ncome influences a consumer’s willingness to sacrifice choice to save on costs. Among low-income adults with employersponsored insurance—defined as family income below 200 percent of the federal poverty level, or $36,800 for a family of four in 2003—two-thirds (67%) were willing in 2003 to give up some choice of hospitals and physicians. In comparison, 54 percent of adults with employer coverage and incomes at least 400 percent of poverty were willing to sacrifice choice. That choice-cost preferences would differ by income is not surprising, given that costs would be of greater concern to people with more limited financial resources. What is surprising is that the magnitude of the difference between the lowest and highest income groups is not larger.

Although more affluent consumers were more inclined overall to favor provider choice over cost savings, even the highest income group has become increasingly willing to sacrifice choice (54% in 2003 vs. 50% in 2001). This result suggests that, while out-of-pocket costs may represent a heavier burden for low-income people, the impact of increased patient cost sharing likely has been felt across a broad spectrum of incomes.

Tough Trade-Offs for People with Chronic Conditions

eople living with chronic conditions—such as diabetes, asthma or depression—usually require ongoing medical care and often rely on specialty and hospital care more than healthy adults. Therefore, it is often assumed that people with chronic conditions would be less willing to limit their choice of providers to save on costs. However, precisely because people with chronic conditions need and use more health services, they shoulder a higher outof- pocket cost burden and have been hit harder by the cost-sharing increases of the past few years than healthy adults. Among chronically ill adults with employer-sponsored insurance, 56 percent said they were willing to accept limited choice of providers to save on costs in 2003 (see Figure 2). This level of willingness is only slightly lower than the 59 percent reported by all working-age adults with employer coverage.

The same income patterns observed for all working-age adults also hold true for those with chronic conditions: The lower the income, the greater the willingness to sacrifice choice to save on out-of-pocket costs. Among the lowest-income group with chronic conditions, 68 percent would limit provider choice to get cost savings, compared with 51 percent of the highest-income group—a larger gap than for all workingage adults with employer coverage. Even for the highest-income group with chronic conditions, however, at least half now say they would sacrifice provider choice to save on costs—a substantial increase from the 45 percent who were willing to make this trade-off in 2001.

At each income level, willingness by chronically ill people to give up choice to gain cost savings has increased significantly: 5 to 6 percentage points—a substantial increase for a two-year period. These increases are larger than those reported by people without chronic conditions, and one likely explanation is that the increase in patient cost sharing has fallen most heavily on people with chronic conditions,2 making them more willing to sacrifice choice to save on costs. Within the lowest-income group, people with chronic conditions are now at least as likely as those without chronic conditions to be willing to give up choice—about two-thirds of both groups.

Opinions Diverse and Divided

mericans are deeply divided over the tradeoff between unfettered choice of physicians and hospitals and lowering their out-of-pocket health costs. While 59 percent of working-age adults with employer coverage would limit provider choice for lower costs, a large minority (40%) was unwilling. And substantial minorities feel intensely about this hot-button issue: 20 percent were strongly willing to limit provider choice, while 21 percent were strongly unwilling (see Figure 3).

Examining the changes in how intensely Americans feel about the choice-cost trade-off indicates Americans’ preferences are evolving along a continuum. Between 2001 and 2003, the proportion of all working-age adults with employer coverage strongly unwilling to limit provider choice declined from 25 percent to 21 percent. The somewhat willing category remained unchanged at 19 percent, but the category that gained the most was the somewhat willing category—36 percent in 2001 vs. 39 percent in 2003. The fact that this category, rather than the strongly willing category, saw the significant growth suggests that consumers’ growing willingness to limit choice may still be soft.

A similar pattern generally held true within each income group. For example, within the highest-income group, the proportion strongly unwilling to limit choice declined from 28 percent to 24 percent, while the proportion somewhat willing to limit choice grew from 35 percent to 38 percent between 2001 and 2003.

Across income groups, there was not much difference in the proportion of people with mild preferences—those who were somewhat willing or somewhat unwilling—about giving up choice to save costs. The most notable difference among the income groups lies in the proportion of those who express greater intensity in preferences: Low-income people with employer coverage were about twice as likely as higher-income people with employer coverage to be strongly willing to sacrifice choice (31% vs. 16%). At the opposite end, a much higher proportion of high-income people were strongly unwilling to limit choice compared with low-income people (24% vs. 15%).

Implications

iven the diversity of choice-cost opinions, it is striking that in recent years so many employers have chosen to adopt broader provider networks and increase patient cost sharing. However, this trend in employer insurance offerings is consistent with previous research finding that firms’ health benefit decisions are substantially influenced by the preferences of the most highly compensated workers.3 Recent changes in health insurance offerings appear to have been driven by a minority of influential, highly paid workers dissatisfied with restricted provider choice and other aspects of tightly managed care.

Offering a variety of insurance products representing different choice-cost options would satisfy the largest number of consumers. Yet, in recent years, many employers, faced with high administrative costs and risksegmentation issues that come with offering multiple health plans, have reduced the range of insurance options offered to workers. For example, fewer employees are now offered a health maintenance organization (HMO) as one of their insurance options. Only 47 percent of covered workers had access to an HMO product in 2003, down from 64 percent in 1996.4 Thus, among people willing to limit provider choice in return for lower costs, fewer are now able to exercise those preferences. And among consumers who maintained access to HMOs, some may have received more provider choice and paid more for it, than they would have preferred, because many HMOs have broadened their networks and eased care restrictions in exchange for higher premiums.

The finding that more insured Americans are willing to trade choice for lower costs raises the question of whether there may be renewed interest in restrictive provider network products. Employers and insurers have been reluctant to risk employee discontent by returning to restrictive networks, but with health costs continuing to outpace wage growth, resistance to these products may lessen. Rather than returning to traditional restrictive networks, some health plans have begun to introduce highperformance networks, which they hope will be more appealing to consumers because the narrow networks will consist of providers the plans have identified to be both cost effective and high quality.5

As an alternative to offering a range of health plans, a few employers and insurers are starting to offer products that carry multiple options. Tiered-provider networks, for example, allow consumers to make trade-offs between costs and provider choice instead of having health plans make the decisions, and so may prove more attractive to employers and consumers than more restrictive plans. Conceptually akin to tiered-pharmacy benefits, which have become the dominant form of prescriptiondrug coverage, tiered-provider networks have faced many operational challenges as well as strong resistance from providers, and have not been widely adopted by employers.6 These results, however, suggest that, in principle at least, tiered-provider networks and other insurance products that offer consumers multiple choice-cost options could attract a sizeable market.

As health cost increases continue to outpace income growth, more consumers may become willing to restrict their choice of providers to ease their out-of-pocket cost burden. And, some who are now only somewhat willing to limit choice may become more strongly inclined to do so and may seek access to lower-cost, limited-choice insurance products. Whether employers provide such options likely will depend on whether they perceive enough demand for those products from their highly paid workers—often the portion of their workforce for which recruitment and retention concerns are greatest. If employers don’t see the need to provide lower-cost options to satisfy highearning workers, then it is unlikely that these options will be offered broadly. Increasingly, consumers willing to limit provider choice for lower costs may find no way of satisfying those preferences. The result could be lower take-up of employer-sponsored insurance and an increase in uninsured Americans.

Data Source

The findings reported in this Issue Brief are based on an analysis of the CTS Household Survey, a nationally representative telephone survey conducted in 1996-97, 1998-99, 2000-01 and 2003. For discussion and presentation, we refer to a single calendar year for the first three surveys (1997, 1999 and 2001). The first three rounds of the survey contain information on about 39,000 adults aged 18- 64, including 28,000 with employersponsored insurance; the 2003 survey contains responses from about 30,000 adults aged 18-64, including 20,500 with employer-sponsored insurance.

To determine whether people had chronic conditions, the survey asked adult respondents whether they had been diagnosed with one of more than 10 chronic conditions and whether they had seen a doctor in the past two years for the condition. The list of chronic conditions includes asthma, arthritis, diabetes, chronic obstructive pulmonary disease, heart disease, hypertension, cancer, benign prostate enlargement, abnormal uterine bleeding and depression. Because the CTS list of conditions is not exhaustive, the estimate of the prevalence of chronic conditions is likely conservative.
