Introduction

As policymakers consider various ways to contain the rising costs of health care, it is useful to examine the patterns of spending on health care throughout the United States. In 2004, the United States spent $1.9 trillion, or 16 percent of its gross domestic product (GDP), on health care. This averages out to about $6,280 for each man, woman, and child. However, actual spending is distributed unevenly across individuals, different segments of the population, specific diseases, and payers. For example, analysis of health care spending shows that: • Five percent of the population accounts for almost half (49 percent) of total health care expenses. • The 15 most expensive health conditions account for 44 percent of total health care expenses. • Patients with multiple chronic conditions cost up to seven times as much as patients with only one chronic condition. Further detailed analyses of these spending patterns, how they change over time, and how they affect different payers such as Medicare, Medicaid, private insurers, employers, and consumers shed important light on how to best target efforts to contain rapidly rising health care costs. Much of the information included in this report comes from the Medical Expenditure Panel Survey. (See Box 1.)

Background

Health care expenses in the United States rose from $1,106 per person in 1980 ($255 billion overall) to $6,280 per person in 2004 ($1.9 trillion overall).1 During this period, health care costs grew faster than the economy as a whole. As a consequence, health spending now accounts for 16 percent of the GDP, compared to 9 percent in 1980. With the aging of the population and the accelerating pace of medical innovation, this trend is likely to continue. Those struggling to develop strategies to reduce or contain costs consider whether efforts should be targeted broadly across the entire health care system or more narrowly at specific areas or aspects of care. For example, is the continuing rise in health care expenses due to the increased. cost of treatment per case? To the growth and aging of the population? To the rise in the number of people treated for the most expensive conditions? Examining the distribution of health care expenses among the U.S. population helps to determine the expenses for different segments of the population, what diseases cost the most, and how public and private payers are affected. This information sheds light on areas where changes in policy might bring about the greatest savings.

How are U.S. health care expenses distributed?

A small proportion of the total population accounts for half of all U.S. medical spending Half of the population spends little or nothing on health care, while 5 percent of the population spends almost half of the total amount.2 In 2002, the 5 percent of the U.S. community (civilian noninstitutionalized) population that spent the most on health care accounted for 49 percent of overall U.S. health care spending (Chart 1). Among this group, annual medical expenses (exclusive of health insurance premiums) equaled or exceeded $11,487 per person. In contrast, the 50 percent of the population with the lowest expenses accounted for only 3 percent of overall U.S. medical spending, with annual medical spending below $664 per person. Thus, those in the top 5 percent spent, on average, more than 17 times as much per person as those in the bottom 50 percent of spenders.2 From 1977 to 1996, the overall distribution of health care expenses among the U.S. population remained remarkably stable (Table 1), according to data from MEPS and its predecessor surveys.3,4 In 1977, the 1 percent of the population with the highest expenses accounted for 27 percent of all expenses, the top 5 percent accounted for 55 percent, and the bottom 50 percent accounted for 3 percent. However, the concentration of expenses at the top has decreased in recent years. The total expenses accounted for by the top 1 percent of spenders declined from 28 percent in 1996 to 22 percent in 2002, and the amount for the top 5 percent dropped from 55 to 49 percent in the same time period.4 The lower 50 percent of spenders remained at 3 to 4 percent of total expenditures during this period.

Older people are much more likely to be among the top-spending percentiles The elderly (age 65 and over) made up around 13 percent of the U.S. population in 2002, but they consumed 36 percent of total U.S. personal health care expenses. The average health care expense in 2002 was $11,089 per year for elderly people but only $3,352 per year for working-age people (ages 19-64).5 Similar differences among age groups are reflected in the data on the top 5 percent of health care spenders. People 65-79 (9 percent of the total population) represented 29 percent of the top 5 percent of spenders. Similarly, people 80 years and older (about 3 percent of the population) accounted for 14 percent of the top 5 percent of spenders (Chart 2).2 However, within age groups, spending is less concentrated among those age 65 and over than for the under-65 population. The top 5 percent of elderly spenders accounted for 34 percent of all expenses by the elderly in 2002, while the top 5 percent of non-elderly spenders accounted for 49 percent of expenses by the non-elderly.4 A principal reason why health care spending is spread out more evenly among the elderly is that a much higher proportion of the elderly than the nonelderly have expensive chronic conditions. Studies show initial persistence of expenses The data just cited show that health care expenses are heavily concentrated in a single year. Over a 2-year period, there is a fairly high degree of persistence of expenditures.6 Of those individuals ranked at the top 1 percent of the health care expenditure distribution in 2002, 25 percent maintained this ranking with respect to their 2003 health care expenditures The proportion of the population that remained in the top 1 percent from 1996 to 1997 was only 14 percent. This means that the proportion of the population in the highest percentile of the health care expenditure distribution that retained this ranking from 2002 to 2003 was nearly double the proportion in the 1996-97 period.7 In 2002, the top 5 percent of the population accounted for 49 percent of health care expenditures. Of people ranked in the top 5 percent of the health care expenditure distribution, 34 percent retained this ranking with respect to their 2003 health care expenditures. Similarly, the top 10 percent of the population accounted for 64 percent of overall health care expenditures in 2002, and 42 percent of this subgroup retained the top decile ranking with respect to their 2003 health care expenditures. Over longer periods of time, a considerable leveling of expenses takes place. In a study of Medicare enrollees, researchers found that although the top 1 percent of spenders accounted for 20 percent of expenses in a particular year, the top 1 percent of spenders over a 16-year period accounted for only 7 percent of expenses.8 The researchers concluded that there is a substantial leveling of expenses across a population when looking over several years or more compared to just a single year. An acute episode of pneumonia or a motor vehicle accident might lead to an expensive hospitalization for an otherwise healthy person, who might be in the top 1 percent for just that year but have few expenses in subsequent years. Similarly, many people have chronic conditions, such as diabetes and asthma, which are fairly expensive to treat on an ongoing basis for the rest of their lives, but in most years will not put them at the very top of health care spenders. However, each year some of those with chronic conditions will have acute episodes or complications requiring a hospitalization or other more expensive treatment. The Medicare study just discussed8 did not control for factors such as the overall increase in the quantity and intensity of services over time. Another study controlled for these factors in examining how the distribution of expenses changes over the major phases of an average person’s lifetime.9 The study used insurance company data on 3.75 million enrollees and data from the Medicare Current Beneficiary Survey.a It found that 8 percent of health care expenses occurred during childhood (under age 20), 13 percent during young adulthood (20-39 years), 31 percent during middle age (40-64 years), and nearly half (49 percent) occurred after 65 years of age. Among people age 65 and older, three-quarters of expenses (or 37 percent of the lifetime total) occurred among individuals 65-84 and the rest (12 percent of the lifetime total) among people 85 and over. The total per capita lifetime expense was calculated to be $316,600. People with high overall health expenses also have high out-of-pocket expenses relative to income Out-of-pocket costs can impose a significant financial burden on individuals and families. These expenses include deductibles, copayments, and payments for services that are not covered by health insurance. Over half the people in the top 5 percent of all health care spenders had out-ofpocket expenses (not including out-of-pocket health insurance premiums) over 10 percent of family income. More specifically: • Thirty-four percent had out-of-pocket medical expenses that exceeded 10 percent of family income. • Eighteen percent had out-of-pocket expenses in excess of 20 percent of family income. People in the bottom 50 percent of the distribution were much less likely to have financial burdens from medical care. For example: • Five percent of people in the bottom 50 percent had out-of-pocket expenses that exceeded 10 percent of family income. • Three percent had out-of-pocket expenses greater than 20 percent of family income.2 People with high health care expenses have lower health status How people view their own health is strongly correlated with their level of health care expenses. Using a respondent-reported overall health status measure (ranging from poor to excellent), a study based on MEPS 2002 data found that people in the highest 5 percent of the distribution of medical expenses were 11 times as likely to be in fair or poor physical health as people in the bottom half of that distribution (45 percent vs. 4 percent).

Question 13 options:

UTStarcom is a global leader in the manufacture, integration, and support of networking and telecommunications systems. The company sells broadband wireless products and a line of handset equipment to operators in emerging and established telecommunications markets worldwide. The following excerpt was obtained from the 2004 10-K of UTStarcom, Inc., which reported material weaknesses in the company’s internal controls. In describing the company’s remediation efforts, the company stated that “planned remediation measures are intended to address material weaknesses related to revenue and deferred revenue accounts and associated cost of sales.”

These material weaknesses were evidenced by the identification of six separate transactions aggregating approximately $5 million in which revenue was initially included in the company’s fourth-quarter 2004 financial statements before all criteria for revenue recognition were met. In addition, there were other transactions for which there was insufficient initial documentation for revenue recognition purposes but which did not result in any adjustments to the company’s fourth-quarter 2004 financial statements. If unremediated, these material weaknesses have the potential of misstating revenue in future financial periods. The company’s planned remediation measures include the following:

• “The Company plans to design a contract review process in China requiring financial and legal staff to provide input during the contract negotiation process to ensure timely identification and accurate accounting treatment of nonstandard contracts.”

• “In March 2005, the Company conducted a training seminar regarding revenue recognition, including identification of nonstandard contracts, in the United States and, in April 2005, the Company conducted a similar seminar in China. Starting in May 2005, the Company plans to conduct additional training seminars in various international locations regarding revenue recognition and the identification of nonstandard contracts.”

• “At the end of 2004, the Company began requiring centralized retention of documentation evidencing proof of delivery and final acceptance for revenue recognition purposes.”

  1. What features of this case should have indicated to the auditor a potentially heightened risk of fraudulent financial reporting?

  2. Using the previous disclosures as a starting point, identify challenges regarding internal controls that a company may face in doing business internationally.

  3. The company had disclosed its planned remediation efforts for 2004. How might the auditor have used that information in planning the 2005 audit?

  4. Considering potential analytical procedures relevant to the revenue cycle, identify analytics that the auditor might use in 2005 to provide evidence that the problems detected in 2004 have been remedied.

  5. Considering potential substantive tests of revenue, identify procedures that might be applied in 2005 to provide evidence that the problems detected in 2004 have been remedied.
