Beschreibung

Statistical Methods in Healthcare In recent years the number of innovative medicinal products and devices submitted and approved by regulatory bodies has declined dramatically. The medical product development process is no longer able to keep pace with increasing technologies, science and innovations and the goal is to develop new scientific and technical tools and to make product development processes more efficient and effective. Statistical Methods in Healthcare focuses on the application of statistical methodologies to evaluate promising alternatives and to optimize the performance and demonstrate the effectiveness of those that warrant pursuit is critical to success. Statistical methods used in planning, delivering and monitoring health care, as well as selected statistical aspects of the development and/or production of pharmaceuticals and medical devices are also addressed. With a focus on finding solutions to these challenges, this book: * Provides a comprehensive, in-depth treatment of statistical methods in healthcare, along with a reference source for practitioners and specialists in health care and drug development. * Offers a broad coverage of standards and established methods through leading edge techniques. * Uses an integrated case study based approach, with focus on applications. * Looks at the use of analytical and monitoring schemes to evaluate therapeutic performance. * Features the application of modern quality management systems to clinical practice, and to pharmaceutical development and production processes. * Addresses the use of modern statistical methods such as Adaptive Design, Seamless Design, Data Mining, Bayesian networks and Bootstrapping that can be applied to support the challenging new vision. Practitioners in healthcare-related professions, ranging from clinical trials to care delivery to medical device design, as well as statistical researchers in the field, will benefit from this book.

Foreword

Twenty-five years ago we launched an interesting experiment, ‘The National Demonstration Project for Quality Improvement in Healthcare’. It was a modest experiment bringing together twenty-one healthcare providers with twenty-one top industrial companies to explore whether industrial quality methods would work in healthcare settings. The results of this experiment were published as Curing Health Care: New Strategies for Quality Improvement. The statistical methods used by most of these healthcare providers were fairly basic tools of quality improvement; yet, many of the improvements were significant.

Looking back this many years later, there was no reason to be surprised by these results. Statistical methods had been used in many areas of healthcare for almost as many years as statistical methods had been used by any organization. Florence Nightingale was one of the first honorary members of the American Statistical Association, an organization that celebrated its 150th anniversary twenty-two years ago. Her pioneering work using clear, simple graphical methods to discover causes of death in hospitals during the Crimean War and alter British barracks was well known and celebrated. Basic, simple statistical methods to explore, understand and present data are as effective in healthcare applications as in any other endeavour.

But somehow, the science of quality control and quality improvement had passed healthcare by. Starting with Shewhart's control chart in 1924, statistical quality control had progressed quickly during the Second World War, and had been widely adopted and used by post-war Japan to become a leading producer of high-quality products. It had been rediscovered in the United States in the 1980s, and widely applied throughout the world in the 1980s and 1990s by companies in almost every competitive industry. Healthcare had evolved many methods of quality assurance, risk management and quality measurement, for the most part independent of what was happening in industry.

In some areas of healthcare, particularly in drug and medical device development and production, sophisticated methods had been created and widely used. Researchers in biostatistics, biometrics and clinical trials had developed and employed some of the most advanced statistical methods, and in turn contributed much to the statistical literature. These methods, however, did not seem to translate easily to the practice of continuous quality improvement in hospital-based care or general clinical practice. There was a considerable gap between what we knew how to do and what we were doing.

The National Demonstration Project evolved into the Institute for Healthcare Improvement, and the growing network of healthcare providers became increasingly adept in learning from sources outside of healthcare, adapting these methods to healthcare applications, and sharing encouraging results with each other. It was not only the statistical tools. The healthcare organizations picked up the methods of putting these tools to use in a scientific approach to improvement using PDSA (Plan-Do-Check/Study-Act), Juran's Quality Improvement Steps, Motorola/General Electric's Define-Measure-Analyse-Improve-Control (Six Sigma Quality), and full-scale implementations of the Toyota Production System (Lean).

Healthcare organizations around the world have formed collaboratives, networks and not-for-profit organizations to share these methods and statistical tools. Thousands of doctors, nurses and other practitioners now routinely attend healthcare quality conferences and daily participate in online courses, web-based sharing and local working groups. Organizations such as the Institute for Healthcare Improvement have tried to structure some of this learning through devices such as IHI's Improvement Roadmap and the Open School, but there has not been a simple place to find the statistical tools used in healthcare improvement until now.

Faltin, Kenett and Ruggeri have brought together leading researchers and practitioners in statistical methods to provide a wealth of methods in one place. Starting with some of the most sophisticated methods used in the development of pharmaceutical products and medical devices, and ending with applications to healthcare management, they have managed to cover amazing ground. The chapters on control charts bring together some of the best methods of statistical process control (SPC) in healthcare, and even cover some of the abuses in the use of control charts. The chapter ‘Six Sigma in Healthcare’ gives a remarkably thorough discussion of both Six Sigma and how it is being applied by many healthcare organizations in Europe and the USA.

But this book goes much further than the typical statistics text and addresses serious policy issues such as kidney allocation and offers advanced statistical methods as an approach to this critical problem. Another critical issue in healthcare, vaccine safety evaluation, is also addressed. In this time of crises in healthcare costs, the economics of healthcare is becoming a major issue. Here too, statistical methods have a large part to play.

The core of healthcare is, of course, clinical outcomes. Statistical methods play a critical role in outcomes analysis. Bias in modelling and monitoring health outcomes are addressed in a chapter by Grigg. Biggeri and Catelan discuss disease tracking. Guglielmi, Ieva, Paganoni and Ruggeri address process indicators and outcome measures in an important area, and Negri gives an excellent discussion of the special tool of meta-analysis.

We no longer need to discuss the value of statistical tools and quality improvement methods in healthcare. The value has been demonstrated thousands of times. What is needed is a comprehensive compilation of these tools in one place written by careful, knowledgeable authors. We should all be grateful to Faltin, Kenett and Ruggeri for providing it.

Preface

This book has its origins in the confluence of two realizations. First, that the availability and quality of healthcare is the defining issue of our time. And second, that statistics as a discipline pervades every aspect of the healthcare field.

Statistical Methods in Healthcare illustrates the spectrum of statistical applications to healthcare. From pharmaceuticals to health economics, drug product development to facilities management, clinical outcomes to electronic medical records, risk assessment to organ allocation, statistics has permeated every corner of healthcare. Accordingly, we have assembled here an array of chapters, prepared by a broadly international group of leading authors, which address all of these topics, and many more. Our objective was not to touch upon every area of statistical application in healthcare – that would be impossible. Rather, our purpose has been to span, as best we can, the diverse domains to which statistics has been applied and, thereby, to contribute to the evolution of statistical methods in healthcare applications.

The book consists of 23 chapters organized in five parts:

Part One: Statistics in Development of Pharmaceutical Products
This part consists of chapters dealing with clinical trials, pharmacometrics, risk management in drug product development, statistical aspects in current regulatory guidelines, and future challenges in drug development.
Part Two: Statistics in Outcomes Analysis
The second part deals with monitoring healthcare and diseases, a detailed case study on the treatment of acute myocardial infarction patients, and a chapter dedicated to meta-analysis.
Part Three: Statistical Process Control in Healthcare
Applications of statistical process control in healthcare are gaining widespread acceptance. In this part we present examples from healthcare, clinical studies and applications of Six Sigma in healthcare.
Part Four: Applications to Healthcare Policy and Implementation
This part is focused on aspects of policy and implementation, including healthcare economics, benchmarking, vaccination policy and allocation procedures in kidney transplant surgery.
Part Five: Applications to Healthcare Management
This final part covers various aspects of healthcare delivery as a service, including payment procedures, electronic medical records and facilities management.

Not surprisingly, such an effort has been the work of contributors from many fields. Statistical Methods in Healthcare integrates contributions from statisticians, economists, physicians, epidemiologists, operations researchers, actuaries and managers, among others. The outcome captures perspectives from all of these disciplines, providing an integrated interdisciplinary view reflecting the richness and complexity of healthcare applications.

Our hope and belief is that this collective effort will prove valuable to those in a wide array of professions which in some way touch upon healthcare. Not only statisticians, but researchers, physicians and administrators will find here statistical applications with detailed examples representing a variety of problems, models and methodologies. Students and practitioners alike will discover opportunities to innovate via the use of statistical methods.

We'd like to acknowledge and thank the many people whose contributions have made this work possible. These include, first and foremost, our esteemed colleagues who have contributed chapters to the work, and the outstanding editorial, production and copy-editing teams at Wiley, who followed up our work together on The Encyclopedia of Statistics in Quality and Reliability with another successful outing. And of course, our thanks go especially to our families, for their patience with us while we were preoccupied or otherwise disengaged throughout the duration of this project.

Synopsis

This chapter introduces the regulatory guidelines affecting drug product development and manufacturing that were published by the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) and other regulatory agencies such as the Food and Drug Administration (FDA) and the European Medicines Authority (EMA). The focus of the chapter is on statistical aspects of these documents, thereby setting the stage for the whole book. These guidelines, collectively, deal with quality, safety and efficacy issues in clinical and pre-clinical research, chemistry, manufacturing and controls (CMC). In essence, they link patient clinical outcomes, drug product critical quality attributes, process parameters and raw material attributes. Establishing the link between patient, product and process is the most important challenge of biopharmaceutical companies and regulatory agencies for ensuring safe, effective and economic healthcare. This challenge is being addressed by the recent Quality by Design (QbD) initiatives of the FDA and ICH, which are also discussed.

1.1 Introduction

Healthcare is the treatment and prevention of illness. Healthcare delivery requires both innovators and manufacturers of drug products and medical devices, as well as healthcare providers such as hospitals and family medicine. This book, Statistical Methods in Healthcare, covers a wide range of activities where statistics impacts on the quality of healthcare, starting with the development of drug products and medical devices, followed by the handling of clinical trials, surveillance and statistical process control of health-related outcomes, economics of healthcare, and healthcare management. The book consists of five parts:

Part One: Statistics in Development of Pharmaceutical Products
Part Two: Statistics in Outcomes Analysis
Part Three: Statistical Process Control in Healthcare
Part Four: Applications to Healthcare Policy and Implementation
Part Five: Applications to Healthcare Management.

This chapter is about the fundamentals in drug development and manufacturing as defined by the regulatory agencies that determine what can be marketed to healthcare consumers. We begin with a general introduction to the organizations that produce such guidelines and regulations.

The pharmaceutical industry became more global in the 1960s and 1970s in parallel with worldwide development of pharmaceutical regulations. Moreover, contemporaneous with these developments, increased societal concerns were voiced for faster development of new biopharmaceutical compounds and for reduction of costs of healthcare and new drug development. One of the perceived roadblocks for expeditiously and efficiently developed new drugs was the fragmentation of pharmaceutical regulations among the United States, Japan and Europe. In the 1980s, the European Community initiated harmonization of European national drug regulations and demonstrated that harmonization of national regulations is possible.
