Evidence Based Resource in Anaesthesia and Analgesia MARTIN TRAMÈR (ed.) BMJ Books: London, UK, 2000, 225 pp. Price £30.00. To make a good soup you need good ingredients, and the complexities and controversies surrounding Evidence Based Medicine definitely lend themselves to a quality intellectual soup. Martin Tramèr sets out his objectives quite clearly. His aim is not to publish another conventional textbook. He has succeeded. This book attempts both to address the philosophical controversies and to explain the statistical and practical complexities involved in performing systematic reviews and meta-analyses. The book is in two parts. The first attempts a balanced discourse of the various aspects of evidence based medicine and the second looks at a few poignant topics. The book starts with an eloquent philosophical preamble by Neville Goodman looking at the various comments made in the medical literature by often polarized protagonists. Things then start in earnest with detailed discussion on the state of anaesthetic literature, the methods involved in systemic reviews and the statistics involved in meta-analysis. These chapters describe clearly, although occasionally repetitively, the difficulties in extracting useful information from often poorly performed and reported primary research. As such, this section makes invaluable reading for any potential researcher over and above any concerns about meta-analysis. We need well-conducted reliable research for all sorts of reasons, and aspiring researchers who want to get their work published would do well to heed the methodological quality lessons which attempting to combine primary studies have taught us. The contributions in the second half of the book vary in style. Chapter 6 is an annotated summary of six systematic reviews, whilst Chapter 7 is a single review in itself (dealing with the effects of intra-articular morphine). Chapter 8 gives a fascinating insight into how the Oxford canon of systematic reviews in postoperative nausea and vomiting were conducted, noteworthy because they considered potential harms as well as benefits. The final chapter considers the control of perioperative bleeding. These areas are all put through the meta-scope, the multiple systemic reviews are dissected and analysed, before concluding where the state of the science is, which is frequently and refreshingly inconclusive. The Editor’s aim of providing a balanced appraisal of evidence based medicine is clearly met, and although the authors include most of the major luminaries of evidence based medicine within anaesthesia, their accounts reflect both its shortcomings and merits. The claim in the title to be a resource is also achieved with a comprehensive list of systemic reviews with brief comment, in the appendix, and several useful websites are also detailed. Unfortunately, the publishers’ claim that there will be regular electronic updates is not expanded upon. Also, because of the lag time between the book’s preparation and its publication, there is no mention of the Cochrane Anaesthesia Review Group, which was formed early in 2000. This book has something for everyone – both reviewers learnt a lot from it, although one is an editor within the Cochrane Collaboration and one a relative novice in the field. We expect this book, and its subsequent editions, will become a favourite for trainees seeking knowledge, and is a must when they start designing their research project, but maybe also for ‘old timers’ to reassure them that science has not yet taken away their art. What it does not do, however, is solve the problem of articulating to nonmedics what we should practise instead of Evidence Based Medicine. We hope subsequent courses live up to this most appetizing starter.
