Preface With this Seventh Edition, we celebrate 20 years of serving instructors, students, policymakers, and others, both at home and overseas, with up-to-date information on the dynamic U.S. health care delivery system. Much has changed, and much will continue to change in the future, as the nation grapples with critical issues of access, cost, and quality. Indeed, much of the developing and developed world will also be contending with similar issues.

People in the United States, in particular, have just gotten a taste of a far-reaching health care reform through President Barack Obama’s signature Affordable Care Act (ACA), nicknamed “Obamacare.” To date, this law has produced mixed results that are documented in this new edition.

At the time this edition went to press, we were left with promises of another reform under the slogan “Repeal and replace Obamacare,” a move championed by President Donald Trump, who had made it one of the centerpieces of his presidential campaign. Much remains to be seen as to how this promise will play out.

On May 4, 2017, the U.S. House of Representatives passed the American Health Care Act (AHCA) by a vote of 217 to 213, with Republican support. The bill is likely to undergo significant changes

in the U.S. Senate. Hence, what the new law may eventually look like was unknown at the time this manuscript went to press. As was the case with the ACA, for which the Democratic Party played an exclusive role in its passage, contentious debates, partisanship, and deal making among both Republicans and Democrats have marked the progress in moving the new law through Congress.

Although we have chosen to sidestep any premature speculation about the fate of the ACA and the shape of its replacement, wherever possible, we have presented trends and facts that support certain conclusions. Mainly, experiences and outcomes under the ACA have been highlighted in this edition.

On his first day in office in January 2017, President Trump signed an executive order to “waive, defer, grant exemptions from, or delay the implementation of any provision or requirement of the [Affordable Care] Act that would impose a fiscal burden on any State or a cost, fee, tax, penalty, or regulatory burden on individuals, families, health care providers, health insurers, patients, recipients of health care services, purchasers of health insurance, or makers of medical devices, products, or medications.” This executive order effectively repealed small portions of the ACA that deal with taxation and fees.

Going forward, the issues of universal coverage and affordability of insurance and health care will be critical. Under the ACA, approximately 27 million people remained uninsured, even though the uninsurance rate in the United States dropped from 13.3% to 10.9% between 2013 and 2016. The majority of the newly insured individuals were covered under Medicaid, the nation’s safety net health insurance program for the poor.

Another thorny issue will be how to provide health care for the millions of illegal immigrants who obtain services mainly through hospital emergency departments, and through charitable sources to some extent. Is there a better, more cost-effective way to address their needs?

The affordability of health insurance in the non-employment-based private market was severely eroded under the ACA, mainly for those who did not qualify for federal subsidies to buy insurance. The reason for the rate hikes in this segment was that few young and healthy people enrolled in health care plans under the ACA. Consequently, for many people, premium costs rose to unaffordable levels in 2016. People who really needed to use health care enrolled in much larger numbers than healthier individuals. Such an adverse selection prompted the chief executive of Aetna Insurance, Mark Bertolini, to remark that the marketplace for individual health insurance coverage was in a “death spiral.” Some large insurance companies either pulled out of the government- sponsored health care exchanges or were planning to do so because of financial losses sustained under the ACA.

▶ New to This Edition This edition continues to reference some of the main features of the ACA wherever it was important to provide contextual discussions from historical and policy perspectives. Several chapters cover the main provisions of the 21st Century Cures Act, which, after a long delay, was finally passed by Congress and signed by President Obama in December 2016.

As in the past, this text has been updated throughout with the latest pertinent data, trends, and research findings available at the time the manuscript was prepared. Copious illustrations in the form of examples, facts, figures, tables, and exhibits continue to make the text come alive. Following is a list of the main additions and revisions:

Chapter 9 “Any willing provider” and “freedom of choice” laws under managed care regulations The latest on accountable care organizations

Chapter 10 New section: Recent policies for community- based services

Chapter 11 Updated information on vulnerable subpopulations Expanded coverage on chronically ill patients

Chapter 12 Current issues in health care costs, access, and quality Pay-for-performance in health care Quality initiatives in both the public and private sectors

Chapter 13 Current critical policy challenges Future health policy issues in both the United States and abroad

Chapter 14 Almost all sections have been completely updated New section: No single payer New section: Reforming the reform New section: Universal coverage and access New section: Toward population health

As in the previous editions, our aim is to continue to meet the needs of both graduate and undergraduate students. We have attempted to make each chapter complete, without making it overwhelming for beginners. Instructors, of course, will choose the sections they decide are most appropriate for their courses.

As in the past, we invite comments from our readers. Communications can be directed to either or both authors:

CHAPTER 1 An Overview of U.S. Health Care Delivery

LEARNING OBJECTIVES

■ Understand the basic nature of the U.S. health care system. ■ Outline the key functional components of a health care delivery system. ■ Get a basic overview of the Affordable Care Act. ■ Discuss the primary characteristics of the U.S. health care system. ■ Emphasize why it is important for health care practitioners and managers to understand the

intricacies of the health care delivery system. ■ Get an overview of health care systems in selected countries. ■ Point out global health challenges and reform efforts. ■ Introduce the systems model as a framework for studying the health care system in the United

States.

The U.S. health care delivery system is a behemoth that is almost impossible for any single entity to manage and control.

▶ Introduction The United States has a unique system of health care delivery that is unlike any other health care system in the world. Almost all other developed countries have national health insurance programs run by the government and financed through general taxes. Nearly all citizens in such countries are entitled to receive health care services. Such is not yet the case in the United States, where Americans are not automatically covered by health insurance.

Though U.S. health care is often called a system because is has various features, components, and services, it may be misleading to talk about the American health care delivery “system,” because a true, cohesive system does not exist (Wolinsky, 1988). Indeed, a major feature of the U.S. health care system is its fragmented nature, as different people obtain health care through different means. The system has continued to undergo periodic changes, mainly in response to concerns regarding costs, access, and quality.

Describing health care delivery in the United States can be a daunting task. To facilitate an understanding of the structural and conceptual basis for the delivery of health care services, this text is organized according to the systems framework presented at the end of this chapter. Also, for the sake of simplicity, the mechanisms of health care delivery in the United States are collectively referred to as a system throughout this text.

The main objective of this chapter is to provide a broad understanding of how health care is delivered in the United States. Examples of how health care is delivered in other countries are also presented for the sake of comparison. The overview presented here introduces the reader to several concepts discussed more extensively in later chapters.

▶ An Overview of the Scope and Size of the System

TABLE 1-1 demonstrates the complexity of health care delivery in the United States. Many organizations and individuals are involved in health care. To name just a few: educational and research institutions, medical suppliers, insurers, payers, and claims processors to health care providers. A multitude of providers are involved in the delivery of preventive, primary, subacute, acute, auxiliary, rehabilitative, and continuing care. A large number of managed care organizations (MCOs) and integrated networks now provide a continuum of care, covering many of the service components.

The U.S. health care delivery system is massive, with total employment that exceeded 16.4 million people in 2010 in various health delivery settings. This number included more than 838,000 professionally active doctors of medicine (MDs), 70,480 osteopathic physicians (DOs), and 2.6 million active nurses (U.S. Census Bureau, 2012). The majority of health care and health services professionals (5.98 million) work in ambulatory health service settings, such as the offices of physicians, dentists, and other health practitioners, medical and diagnostic laboratories, and home health care service locations. Smaller proportions of these professionals are employed by hospitals (4.7 million) and nursing and residential care facilities (3.13 million). The vast array of health care institutions in the United States includes approximately 5,795 hospitals, 15,700 nursing homes, and 13,337 substance abuse treatment facilities (U.S. Census Bureau, 2012).
