Winkel P., Zhang N.F. Statistical Development of Quality in Medicine
Wiley – 2007, 280 pages
ISBN: 9780470027776

Our research collaboration started when Per Winkel was struggling with heavily autocorrelated laboratory quality control data. He contacted Nien Fan Zhang and asked for his help to solve the problems. The next time Per Winkel asked for Nien Fan Zhang’s help was when planning to write an English textbook on statistical quality development in medicine. At that time Per Winkel had already written a Danish textbook on this topic [1]. Appendix A on basic statistics, and Chapters 1 and 2 on the theory of control charts and Shewhart charts have been translated from this book and subsequently reviewed and revised by Nien Fan Zhang to secure the statistical rigour. In addition to translating these chapters Per Winkel has added additional clinical examples to Chapters 1 and
2. But the English book needed to address the question on autocorrelated data and risk adjustment, which were only briefly mentioned in the Danish textbook. Since Nien Fan Zhang is doing active research within the areas of time-weighted control charts and control charts for autocorrelated data it was natural to ask Nien Fan Zhang to write the two Chapters, 3 Time-weighted control charts and 4 Control charts for autocorrelated data. In addition Nien Fan Zhang has written Appendix B, which contains a derivation of the control limits for X charts and S charts with unequal sample size, and Appendix C. Per Winkel has written the remaining chapters more directly related to clinical research, namely: the Introduction – on quality of health care in general, Chapter 1Theory of statistical process control, Chapter 2 Shewhart control charts, Chapter 5 Tools of risk adjustment, Chapter 6 Risk-adjusted control charts, Chapter 7 Risk-adjusted comparison of healthcare providers, Chapter 8 Leaing curves, and Chapter 9 Assessing the quality of clinical processes, as well as Appendix A. We have reviewed each other’s chapters. During this process Nien Fan Zhang’s main role, of course, has been to secure the statistical rigour and Per Winkel’s to construct clinical examples when deemed necessary in order to ease understanding.
