1 The Three Ws of Consolidation and Competition in US Health Care Martin Gaynor E. J. Barone Professor of Economics and Health Policy Heinz College Carnegie Mellon University Big Health: Consolidation and Competition under the Affordable Care Act American Enterprise Institute, Washington, D.C., March 1, 2013

2 High and Egregious Pricing Practices A Bitter Pill to Swallow 2

3 Introduction Purpose of talk – Introduce you to basic facts about consolidation and competition in US health care, understand the issues, drivers, consider policy approaches. Organization of Talk: “W W W” – What? – Who Cares? – What Can We Do About It? 3

4 What? 4

5 Health spending – High and increasing. Can’t be sustained without serious strain/harm. Hospital and physician services are ~9.2% of GDP. Prices – High, egregious billing practices. – Prices are a major driver of health spending increases. Quality – Concerns over quality. Innovation, Efficiency, Service – Health system characterized as sclerotic, unresponsive, uncreative. Consolidation – Lots of consolidation (hospitals, physicians, insurers). 5

6 Not a New Problem 6 by Andy Warhol ~ 1985-86 Available via Christie’s $15-20,000

7 It’s The Prices 7 Components of Health Spending Growth, Private ESI Insurance, 2010-2011

8 Once More, With Feeling 8 *Source: Hartman et al., Health Affairs, January 2013, 32(1): 87-99

9 Quality Problems Institute of Medicine – “The U.S. health care delivery system does not provide consistent, high-quality medical care to all people.” – “At least 44,000 people, and perhaps as many as 98,000 people, die in hospitals each year as a result of medical errors that could have been prevented …” 9

10 Hospital Consolidation There has been a tremendous amount of consolidation in the hospital industry. – Mergers and Acquisitions. Over 1,000 deals 1994-present. Consolidation slowed in 2000s, but has picked up recently. Hospital Market Concentration. – Herfindahl-Hirschmann Index (HHI): sum of squared market shares. – Average MSA level HHI. – 1992 - 2,440; about like a market with 4 firms of equal size. – 2006 - 3,261; about like a market with 3 equally sized firms. – FTC/DOJ cutoff for highly concentrated market { HHI = 2,500. – In 2006, 75% of MSAs were highly concentrated. Why Did Hospitals Consolidate? – Response to rise of managed care. – Anticipation of ACA? – Game of “musical chairs.” 10

11 Insurer Consolidation Insurer Consolidation. – Information not as good as for hospitals, but better than for physicians. Large Employer Market. – 1998: HHI = 2,172; about like a market with 5 firms of equal size. – 2006: HHI = 2,956; somewhere between a market with 3 and 4 equally sized firms. – Average insurance market is highly concentrated after 2004. – Concentration starts increasing after 2002 (compared to mid to late 1990s for hospitals). Small Group Market. – Market share of largest carrier has been increasing over time (33% – 2002; 47% 2008). – 87% of states had five firms controlling 75% or more of the market – in 2008; 56% in 2002. 11

12 Physicians, “Vertical” Consolidation There is not nearly as much information about consolidation in the physician market as there is for hospitals. – Size of Physician Practices. Practices getting larger. County HHI for physician practices 4,430 (CA, 2001). Vertical Consolidation – Physicians-hospitals; Insurers-providers. – A great deal of interest in physician-hospital consolidation in – particular. – Most forms of physician-hospital integration peaked in the mid- 1990s (e.g., PHOs), and have declined steadily since then. – The exception is the employment of physicians by hospitals, which has been growing steadily. – Lots of talk about this kind of integration, little in the way of hard #s. – ACOs 428 now; 164 in 2011. More growth expected. 12

13 The Affordable Care Act ACA retains basic structure of US health care system – Therefore, markets have to work. – Exchanges need competition. – Provider markets need to be competitive. For all segments: ESI, exchanges, Medicare, Medicaid,… ACOs – Organizational innovation? – Anticompetitive sham? FTC/DOJ rules. 13

14 Who Cares? 14

15 Who Cares? US uses a market system for providing care and for financing ~50% of it. Therefore we need markets to work as well as they possibly can. If not, we pay. – Higher prices. – Lower quality. – Poor service. – Inefficient, outmoded means of organizing and delivering care. 15

16 In Their Own Words, or Hospital Executives Say the Darndest Things “Cleveland Clinic Diagnoses Health-Care Act “ Wall St. Journal, December 19, 2012 – WSJ: “You are consolidated in the Cleveland area. Do you use that leverage in negotiating prices with health insurers?” – Dr. Cosgrove: “Yes, we do. We also consolidate services and drive efficiency of services across this organization. We've consolidated our hospitals. We've consolidated cardiac surgery, pediatrics, rehab, psychiatric care, obstetrics, to bring them together and have higher quality and lower cost, more efficiency.” – WSJ: “Has that translated into lower prices that you charge to private insurers?” – Dr. Cosgrove: “No. But we know that the payer is going to pay us less [in the future], so we're getting ready.” So Do Financial Analysts (“Fitch: Supreme Court Merger Ruling Could Hurt For-Profit Hospitals,” by Ron Shinkman, Fierce HealthFinance, February 25, 2013) – "Simply put, less industry consolidation means decreased pricing power for hospitals," Fitch said. 16

17 Empirical Evidence – Hospital Prices Competition decreases prices (US, Netherlands). – Mergers lead to price increases of 3.5-53 percent. – Magnitude largely depends on availability of close substitutes Summit-Alta Bates (Bay Area): 28-44% price increases due to merger. French-Sierra Vista (San Luis Obispo): Price increases up to 53% due to merger. – Hospitals that have or acquire market power are able to charge higher prices on a permanent basis. 100% pass-through to consumers. 17

18 Empirical Evidence – Hospital Quality Administered Prices (U.S. Medicare, England) – Competition increases quality (reduces mortality). Substantial impacts – 1.46 percentage points lower mortality rate in least concentrated markets for Medicare heart attack patients. Similar magnitudes in England. English NHS reforms increased responsiveness of hospital choice to hospital quality. Market Determined Prices – Impacts on quality mixed, but mostly positive (U.S., England, the Netherlands). Effects on quality appear to be long lasting. Not much is known about non-mortality aspects of quality – Waiting times, MRSA rates unaffected (England) 18

19 Empirical Evidence – Hospitals, Not-for- Profit, Costs Not-for-Profit/Public Firms – One might think NFP or public hospitals would behave differently. Little evidence that they do so (US). Hospitals respond to competition (US, England, Netherlands). Costs – Efficiencies due to merger possible. Little evidence that they are achieved (US, England). Vertical Integration – Efficiencies possible, anticompetitive impacts possible. Little evidence of efficiencies (US), mixed evidence on price (US). 19

20 Empirical Evidence – Physicians, Insurers Physicians – Not a lot of evidence - some that prices are higher in more concentrated markets. Insurers – Evidence that insurance premiums are higher in more concentrated markets (large employers). – Evidence of substantial market power in the Medigap market. – Evidence that competition has a large effect on premiums in Medicare+Choice. 20

21 Empirical Evidence – Vertical Relations Physician-Hospital Integration – Price - 2 studies; opposite results. – Cost, Quality - little evidence of any impact. Countervailing Power – Some evidence that insurers in concentrated markets pay lower prices to providers. – But, evidence that they also charge higher premiums. ACOs = Anti Competitive Organizations? – No evidence yet, too new. – Some cause for concern due to past behavior. 21

22 Who Pays? If health care prices increase due to consolidation, who pays - insurers? employers? or consumers? CONSUMERS – Evidence shows that increased health benefit costs to employers are passed on to workers in reduced pay (or lower increases), greater cost sharing of premiums, or reduced benefits. 22

23 What Can We Do About It? 23

24 Policy Goals, Framework Overall Goal – Let markets work, encourage responsiveness, innovations. Framework – Set up rules of the road and enforce them. – Support an environment that supports competition. – Need. Basic conditions. Ongoing oversight. 24

25 Policy Options – Supply Side Vigorous Antitrust Enforcement (it’s hard to unscramble and omelet) – Mergers – Anticompetitive Conduct – Safe Harbors Use with care. – Countervailing Power Two wrongs don’t make a right. Facilitating Entry (no artificial barriers to entry) – Entry can take care of problems due to consolidation. – Avoid foreclosure. – New entrants, existing forms. – New entrants, new forms. 25

26 Policy Options Demand Side Policies – Tax Policy End the exclusion of employer-sponsored health insurance. – Selective Contracting. – Tiering/Narrow Networks. – Consumer Information/Transparency. – Consumer Engagement. Rate Regulation – If markets have become too concentrated. – But, doesn’t remove need for competition for quality, service. 26

27 Growth of High Deductible Health Plans 27

28 Expanding the Market - Adding Competitors Wal-Mart next year will cover cardiac and spinal surgeries for more than one million U.S. employees and dependents through bundled payment agreements with six hospitals, including Cleveland Clinic and Mayo Clinic. October 12, 2012. (http://www.advisory.com/Daily-Briefing/2012/10/12/Wal-Mart-six- hospitals-launch-bundled-payments) PepsiCo Inc. last week announced a "rare" bundled payment agreement with Johns Hopkins Hospital that will allow its employees to travel to Baltimore for certain complex surgeries. Dec. 12, 2011. (http://www.advisory.com/Daily- Briefing/2011/12/12/Pepsi-Johns-Hopkins-bundled-payment) Lowe's, Cleveland Clinic hit 'home run' with bundled payment deal. October 26, 2010. (http://www.advisory.com/Daily- Briefing/2010/10/26/Lowes-Cleveland-Clinic-hit-home-run-with- bundled-payment-deal) 28

29 Consolidation - Hospitals Over 1,000 hospital mergers since mid-90s Most urban areas are now dominated by 1-3 large hospital systems 29

30 Hospital Consolidation, 2 Large change in concentration of hospital market shares. – Like moving from market with 5 equal size firms to one with 3 equal size firms. – FTC/DOJ cutoff for “highly concentrated” – HHI  2,500. 30

31 Hospital Consolidation, 3 Most MSAs are highly concentrated. Most MSAs have become more concentrated. 31

32 Insurer Consolidation 32
