This book remains at least as useful in 2009 as I am sure it was in 2002 when initially published. Increasingly we are expected, rightly so, to embrace and further the ethos of evidence-based practice and for the statistically naïve this often involves a large dose of herd behaviour washed down with a hefty slug of blind faith! How fabulous then to come across a book such as this. Olajide Ajetunmobi (a specialist registrar in psychiatry in 2002) has, as suggested by the title, made the arena of critical appraisal open to all. He has taken almost anything that is open to critical appraisal and dedicated a concise and clear chapter on exactly how to do just that. There are 12 chapters in all and I couldn't help but think that a different publisher may have been tempted to publish each of these as a stand alone text, perhaps as part of a 12-volume series - `Quick & Critical'! The first chapter, although entitled `Basic Stats', totals 58 pages which is more than a quarter of the book! All statistical tests and terminology commonly used, and more, are described in a clear fashion. The second discusses the issue of study design and which design is appropriate for each particular scenario and the next five chapters deal with appraisal of each of the common study designs from randomised controlled trial to cross sectional surveys. The eighth chapter discusses survival data and then following on from this, audit, systematic reviews, economic evaluation and qualitative studies are appraised. The book is a great size - big enough without being daunting - and is written in a clear, well thought out style. There are plenty of tables and diagrams as needed and examples are used at every possible opportunity. The end of each chapter concludes with important points and there is a glossary at the back of the book along with references and suggested further reading. I thought this was a great little book - good value and one of those books that will always be worth having whether it's for a complete guide or the odd refresher on how to appraise a particular study.
