FOREWORD

Nancy M. Schlichting

There has never been a more important and exciting time in the journey to achieve excellence in healthcare quality. After more than eight years since the Institute of Medicine released its groundbreaking report, To Err Is Human: Building a Safer Health System, on the poor state of healthcare quality in the United States, there is significant momentum for fundamen- tal change to improve quality. The momentum is being felt in a number of important venues:

• In the government world, as legislators and administrators are working to increase the incentives for quality in governmental programs

• In the business world, as companies are redesigning health benefit plans to encourage more involvement of the employees in their choice of health- care providers based on performance

• In the insurance world, as health plans are evaluating providers based on quality indicators

• In the provider world, as hospitals and physicians are investing in new infor- mation technology to provide more consistent and safer quality of care for their patients

• In the consumer world, as individuals are seeking out information about quality before choosing a physician, a hospital, or a health plan

The importance of this momentum cannot be overstated. It will cre- ate enormous opportunities for learning that can be spread across the coun- try, more alignment of incentives among all stakeholders, more informed consumers, and greater availability of accurate and useful information for decision making.

The second edition of The Healthcare Quality Book is a resource for all learners and participants in this critical process of change. It is a guide for quality improvement that incorporates both theoretical models and practical approaches for implementation. The editors have brought together some of the best minds in healthcare to offer insights on leadership strat- egy, tools, organizational design, information technology, legal and reg- ulatory issues, and, most important, the patient experience. The Healthcare Quality Book will serve all who have a passion for changing the quality

paradigm and creating an ideal patient and family experience. Now is the time for action! The editors of The Healthcare Quality Book are providing the necessary resources. I am confident the readers will be part of the healthcare quality solution.

PREFACE

Change is constant, and no statement is more appropriate for the health- care industry. Since the first edition of this textbook, healthcare costs have increased beyond the rate of inflation, the number of uninsured individu- als has grown dramatically, employers and consumers are facing a greater share of healthcare expenses, and navigation of the complex and compli- cated healthcare system has become a burden on the public. Our health- care crisis permeates every aspect of the industry—the delivery of medical care, the financing of our system, and the quality of healthcare we receive.

In our fragmented, unsustainable, and uncertain healthcare system, one element remains steadfast—healthcare quality is paramount. Healthcare that is safe, effective, efficient, equitable, patient centered, and timely is fundamen- tal to all potential healthcare reform plans—big or small, national or regional.

This textbook provides a framework, a context, strategies, and prac- tical tactics for all stakeholders to understand, learn, teach, and lead health- care improvement. We have assembled an internationally prominent group of contributors for the best available current thinking and practices in each of their disciplines.

This edition has evolved from the first. New case studies have been added, up-to-date content has been included, new study questions have been posed, and a new chapter has been added. The framework of the book remains constant. Chapters 1 through 4 discuss foundational healthcare quality principles. Chapters 5 through 16 discuss critical quality issues at the organizational and microsystem levels. Chapters 17 through 19 detail the influence the environment has on the organizations, teams, and indi- viduals delivering healthcare services and products.

In Chapter 1, Maulik Joshi and Donald Berwick center on the patient and articulate key findings from national, sentinel reports of healthcare qual- ity over the last ten years. In Chapter 2, Leon Wyszewianski discusses the fundamental concepts of quality. In Chapter 3, David Ballard and colleagues discuss medical practice variation and provide an updated case study, and Kevin Warren has revised Chapter 4 to reflect the latest quality improvement tools and programs.

In Chapter 5, Robert Lloyd discusses measurement as a building block in quality assessment and improvement. John Byrnes focuses on data collection and its sources in Chapter 6, and Jerod Loeb and colleagues discuss analytic opportunities in quality data in Chapter 7. In Chapter 8, David Nash and col- leagues detail a physician profiling system. In Chapter 9, Susan Edgman-Levitan tackles an often discussed but less understood area of patient satisfaction—expe- riences and perspectives of care—and includes an update on the latest surveys. In Chapter 10, Michael Pugh aggregates data into a management tool called the Balanced Scorecard. Frances Griffin and Carol Haraden in Chapter 11 and

xv

Richard Ward in Chapter 12 dive deeper into two evolving subjects essential to driving performance improvement—patient safety and information technology, respectively. Chapters 13 through 15, by James Reinertsen, A. Al-Assaf, and Scott Ransom and colleagues, provide a triad of keys for change in organiza- tions seeking to become high performers. The triad represents leadership, infra- structure, and strategy for quality improvement. Chapter 16, by Valerie Weber and John Bulger, is a compilation of strategies and tactics necessary to change staff behavior.

Chapter 17, by Jean Johnson and colleagues, a new chapter, pro- vides examples of many of the recent national quality improvement initia- tives and an overview of the quality improvement landscape. In Chapter 18, Greg Pawlson and Paul Schyve collaborate to summarize the work of the two major accrediting bodies within healthcare—the National Committee for Quality Assurance and The Joint Commission—and cover the latest changes in the accreditation process. The book concludes with an impor- tant chapter by Francois de Brantes on the power of the purchaser to select and pay for quality services, which he has updated to provide the latest information on pay for performance.

Several of these chapters could stand independently. Each represents an important contribution to our understanding of the patient-centered organizations and environment in which healthcare services are delivered. The science and knowledge on which quality measurement is based are changing rapidly. This book provides a timely analysis of extant tools and techniques.

Who should read this book? The editors believe all current stakeholders would benefit from reading this text. The primary audiences for the book are undergraduate and graduate students in healthcare and business administration, public health programs, nursing programs, allied health programs, and programs in medicine. As leadership development and continuing education programs proliferate, this textbook is a resource for executives and practitioners at the front line. We hope this book will break down the educational silos that currently pre- vent stakeholders from sharing equally in their understanding of patient-cen- tered organizational systems and the environment of healthcare quality.

This textbook and the accompanying instructor manual are designed to facilitate discussion and learning. There are study questions at the end of each chapter in the textbook. The instructor manual contains answers to the study questions and a PowerPoint presentation for each chapter as a teaching aid. For access information, e-mail hap1@ache.org.

SCIENCE AND KNOWLEDGE FOUNDATION

HEALTHCARE QUALITY AND THE PATIENT Maulik S. Joshi and Donald Berwick

Quality in the U.S. healthcare system is not what it should be. Peoplewere aware of this issue for years from personal stories and anec-dotes. Around the end of the last century, three major reports revealed evidence of this quality deficiency:

• The Institute of Medicine’s (IOM) National Roundtable on Health Care Quality report, “The Urgent Need to Improve Health Care Quality” (Chassin and Galvin 1998)

• To Err Is Human (Kohn, Corrigan, and Donaldson 2000) • IOM’s Crossing the Quality Chasm (IOM 2001)

These three reports made a tremendous statement and called for action on the state of healthcare, its gaps, and the opportunity to improve its quality in the United States to unprecedented levels.

Before we begin discussion of these reports, however, let us begin by defining quality, its evolution, and its implications on our work as health- care professionals.

Avedis Donabedian, one of the pioneers in understanding approaches to quality, discussed in detail the various definitions of quality in relation to perspective. Among his conceptual constructs of quality, one view of Donabedian’s (1990) rang particularly true: “The balance of health bene- fits and harm is the essential core of a definition of quality.” The question of balance between benefit and harm is empirical and points to medicine’s essential chimerism: one part science and one part art (Mullan 2001).

The IOM Committee to Design a Strategy for Quality Review and Assurance in Medicare developed an often-cited definition of quality (Lohr 1990):

Quality of care is the degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledge. . . . How care is provided should reflect appropriate use of the most current knowledge about scientific, clinical, technical, interpersonal, manual, cognitive, and organization and management elements of health care.

In 2001, Crossing the Quality Chasm stated powerfully and simply that healthcare should be safe, effective, efficient, timely, patient centered,

and equitable. This six-dimensional aim, which will be discussed later in this chapter, provides the best-known and most goal-oriented definition, or at least conceptualization, of the components of quality today.

Important Reports

In 1998, the Journal of the American Medical Association’s National Roundtable report included two notable contributions to the industry. The first was its assessment of the state of quality. “Serious and widespread quality problems exist throughout American medicine. These problems . . . occur in small and large communities alike, in all parts of the country, and with approximately equal frequency in managed care and fee-for-service systems of care. Very large numbers of Americans are harmed.” The second contribution to the knowl- edge base of quality was a categorization of defects into three broad cate- gories: overuse, misuse, and underuse. The classification scheme of underuse, overuse, and misuse has become a common nosology for quality defects.

Underuse is evidenced by the fact that many scientifically sound prac- tices are not used as often as they should be. For example, biannual mam- mography screening in women ages 40 to 69 has been proven beneficial and yet is performed less than 75 percent of the time.

Overuse can be seen in areas such as imaging studies for diagnosis in acute asymptomatic low back pain or the prescription of antibiotics when not indicated for infections, such as viral upper respiratory infections.

Misuse is the term applied when the proper clinical care process is not executed appropriately, such as giving the wrong drug to a patient or incorrectly administering the correct drug.

Many reports have identified the gap between current and optimal healthcare practice. The studies range from evidence of specific processes falling short of the standard (e.g., children not receiving all their immu- nizations by age two) to overall performance gaps (e.g., risk-adjusted mor- tality rates in hospitals varying fivefold) (McGlynn et al. 2003).

Although the healthcare community knew of many of these quality- related challenges for years, the 2000 publication To Err Is Human exposed the severity of the problems in a way that captured the attention of all key stakeholders for the first time.

The executive summary of To Err Is Human began with these head- lines (Kohn, Corrigan, and Donaldson 2000):

• Betsy Lehman, a health reporter for the Boston Globe, died from an over- dose during chemotherapy.

• Ben Kolb, an eight-year-old receiving minor surgery, died due to a drug mix-up.

• As many as 98,000 people die every year in hospitals as a result of injuries from their care.

4 T h e H e a l t h c a r e Q u a l i t y B o o k

• Total national costs of preventable adverse events are estimated between $17 billion and $29 billion, of which health care costs are over one-half.

These data points focused on patient safety and medical errors as per- haps the most urgent forms of quality defect. Although many had spoken about improving healthcare, this report spoke about the negative—it framed the prob- lem in a way that everyone could understand and demonstrated that the situ- ation was unacceptable. One of the basic foundations for this report was a Harvard Medical Practice study done more than ten years earlier. For the first time, patient safety (i.e., ensuring safe care and preventing mistakes) became a solidifying force for policymakers, regulators, providers, and consumers.

In March 2001, soon after the release of To Err Is Human, IOM released Crossing the Quality Chasm, a more comprehensive report offer- ing a new framework for a redesigned U.S. healthcare system. Crossing the Quality Chasm provided a blueprint for the future that classified and uni- fied the components of quality through six aims for improvement, chain of effect, and simple rules for redesign of healthcare.

The six aims for improvement, viewed also as six dimensions of qual- ity, are as follows (Berwick 2002):

1. Safe: Care should be as safe for patients in healthcare facilities as in their homes.

2. Effective: The science and evidence behind healthcare should be applied and serve as the standard in the delivery of care.

3. Efficient: Care and service should be cost effective, and waste should be removed from the system.

4. Timely: Patients should experience no waits or delays in receiving care and service.

5. Patient centered: The system of care should revolve around the patient, respect patient preferences, and put the patient in control.

6. Equitable: Unequal treatment should be a fact of the past; disparities in care should be eradicated.

These six aims for improvement can be translated into respective outcome measures and goals. The following points are examples of the types of global measures that can be used to track IOM’s six aims.

• Safe care may be measured in terms of the percentage of overall mortal- ity rates or patients experiencing adverse events or harm.

• Effective care may be measured by how well evidenced-based practices are followed, such as the percentage of time diabetic patients receive all recommended care at each doctor visit, the percentage of hospital-acquired infections, or the percentage of patients who develop pressure ulcers (bed sores) while in the nursing home.

• Efficient care may be measured by analyzing the costs of care by patient, by organization, by provider, or by community.

C h a p t e r 1 : H e a l t h c a r e Q u a l i t y a n d t h e P a t i e n t 5

• Timely care may be measured by waits and delays in receiving needed care, service, and test results.

• Patient-centered measures may include patient or family satisfaction with care and service.

• Equitable care may be viewed by examining differences in quality meas- ures (such as measures of effectiveness and safety) by race, gender, income, or other population-based demographic and socioeconomic factors.

The underlying framework for achieving these aims for improvement depicts the healthcare system in four levels, all of which require changes. Level A is what happens with the patient. Level B reflects the microsystem where care is delivered by small provider teams. Level C is the organiza- tional level—the macrosystem or aggregation of the microsystems and sup- porting functions. Level D is the external environment where payment mechanisms, policy, and regulatory factors reside. Figure 1.1 provides a picture of these four cascading levels. The environment affects how organizations operate, which affects the microsystems housed in them, which in turn affect the patient. “True north” in the model lies at Level A, in the experience of patients, their loved ones, and the communities in which they live (Berwick 2002).

A Focus on the Patient

tical regimens has exploded. Yet, the system falls short of its technical poten- tial. Patients are dissatisfied and frustrated with the care they receive. Providers are overburdened and uninspired by a system that asks too much and makes their work more difficult. Society’s attempts to pay for and prop- erly regulate care add complexity and even chaos.

Demands for a fundamental redesign of the U.S. healthcare system are ever increasing. IOM proposed that a laser-like focus on the patient must sit at the center of efforts to improve and restructure healthcare. Patient-centered care is the proper future of medicine, and the current focus on quality and safety is a step on the path to excellence.

Today, patients’ perception of the quality of our healthcare system is not favorable. In healthcare, quality is a household word that evokes great emotion, including:

• frustration and despair, exhibited by patients who experience healthcare serv- ices firsthand or family members who observe the care of their loved ones;

• anxiety over the ever-increasing costs and complexities of care; • tension between individuals’ need for care and the difficulty and incon- venience in obtaining care; and

• alienation from a care system that seems to have little time for under- standing, much less meeting, patients’ needs.

To illustrate these issues, we will examine in depth the insights and experiences of a patient who has lived with chronic back pain for almost 50 years and use this case study to understand the inadequacies of the current delivery system and the potential for improvement. This case study is repre- sentative of the frustrations and challenges of the patients we are trying to serve and reflective of the opportunities that await us to radically improve the healthcare system. (See the section titled “Case Study” later in the chapter.)

Lessons Learned in Quality Improvement

We have noted the chasm in healthcare as it relates to quality. This chasm is wide, and the changes to the system are challenging. An important mes- sage is that changes are being made, patient care is improving, and the health of communities is beginning to demonstrate marked improvement. Let us take this opportunity to highlight examples of improvement proj- ects in various settings to provide insight into the progress.

Improvement Project: Improving ICU Care 1

One improvement project success story took place in 2002 in the inten- sive care unit (ICU) at Dominican Hospital in Santa Cruz County, California. Dominican, a 379-bed community hospital, is part of the 41- hospital Catholic Healthcare West system.

The staff in Dominican Hospital’s ICU learned an important lesson about the power of evidence over intuition. “We used to replace the venti- lator circuit for intubated patients daily because we thought this helped to prevent pneumonia,” explained Lee Vanderpool, vice president. “But the evidence shows that the more you interfere with that device, the more often you risk introducing infection. It turns out it is often better to leave it alone until it begins to become cloudy, or ‘gunky,’ as the nonclinicians say.”

The importance of using scientific evidence reliably in care was just the sort of lesson that healthcare professionals at Dominican had been learn- ing routinely for more than a decade as they pursued quality improvement throughout the hospital. Dominican’s leaders focused on improving criti- cal care processes, and their efforts improved mortality rates, average ven- tilator days, and other key measures (see Figure 1.2).

Ventilator Bundling and Glucose Control

After attending a conference in critical care, Dominican staff began to focus on a number of issues in the ICU. “The first thing we tackled was venti- lator bundling,” said Glenn Robbins, RPh, responsible for the day-to-day process and clinical support of Dominican’s critical care improvement team. Ventilator bundling refers to a group of five procedures that, performed together, improve outcomes for ventilator patients.2

“We were already doing four of the five elements,” said Robbins, “but not in a formalized, documented way that we could verify.” Ventilator bundling calls for ventilator patients to receive the following: the head of their bed elevated a minimum of 30 degrees; prophylactic care for peptic ulcer disease; prophylactic care for deep vein thrombosis; a “sedation vaca- tion” (a day or two without sedatives); and a formal assessment by a res- piratory therapist of readiness to be weaned from the ventilator.

The team tested ideas using Plan-Do-Study-Act (PDSA) cycles, ran various small tests, and then widened implementation of those that worked. Some fixes were complex, and some were simple. To ensure that nurses checked elevation at the head of the bed, for example, Camille Clark, RN, critical care manager, said, “We put a piece of red tape on the bed scales at 30 degrees as a reminder. We started with one nurse, then two, and then it spread. Now when we [perform rounds] in the ICU, we always check to see that the head of the bed is right. It has become an integrated part of the routine.”

Another important process change included the use of lists to iden- tify and track therapy goals for each patient. The form went through more than 20 PDSA cycles and 25 different versions before it was used 100 per- cent of the time for ICU patients. “We got some pushback from the nurses because it felt to them like double-charting,” said Clark. “So we kept work- ing on it, and incorporating their suggestions, until it became something that was useful to them rather than simply more paperwork.” Getting physi- cians on board regarding the daily goal list and other aspects of improve- ment was also a key factor in their project’s success.

Next, the team turned its attention to the intravenous insulin infusion protocol used in the ICU and intensified efforts to better control patients’ blood sugar. “The literature strongly suggests that controlling hyperglycemia helps reduce mortality in the ICU,” said Aaron Morse, MD, critical care medical director. “We initially trialed a more aggressive protocol on about 30 patients, and we’ve gone through seven or eight PDSA cycles on it. It is now standard protocol, and from the data we have so far, it has been extremely successful. We attribute our very low rate of ventilator-associated pneumo- nia to changes like the ventilator bundle and glucose control.”

Part of introducing a new protocol, or any new idea, involves edu- cation. “We worked to educate the staff on the importance of tight glucose

control in ICU patients,” said Robbins. Equally important is listening to the frontline staff who must implement the new procedures. “The nursing staff provides lots of feedback, which helps us refine our processes. We have vigorous dialogues with both nurses and physicians when we try things.”

At Dominican, the culture of improvement was pervasive for more than a decade, so all employees knew that performance improvement was part of their jobs. “We are in our 12th formal year of continuous performance improvement, and most of the people here have been a part of that from the inception,” said Vanderpool. As a result of the organi- zation’s long-term commitment to quality improvement, Vanderpool said progress was steady on many fronts. “Things that were once barri- ers to change are not today. People know they have the ability to make changes at the work level and show the trends associated with them. People feel empowered.”

“How Did You Get That to Happen?”

Vanderpool said other hospital leaders who were trying to achieve similar improvements as Dominican did in their own quality journeys often asked him the same question: “How did you get that to happen?” He empha- sized the value of creating a culture of improvement, which must start at the top of the organization. He demonstrated his commitment to quality by joining clinical staff on rounds in the ICU on a frequent, yet purpose- fully irregular, basis. “Some organizations overlook the importance of the culture change in performance improvement work,” said Sister Julie Hyer, OP, president of Dominican Hospital. “It is fundamental to create a cul- ture that supports and respects improvement efforts.”
