Davidson's Principles and Practice of Medicine is a comprehensive textbook on clinical medicine. It covers a wide range of topics, including genetic, climatic, and environmental factors in disease, neurological disorders, infectious diseases, and more. The 24th Edition has won several awards for its clear and concise writing, comprehensive coverage, and up-to-date information.

Well over two million copies of Davidson’s Principles and Practice of Medicine have been sold since it was first published in 1952. Now in its 24th Edition, Davidson’s is regarded as a ‘must-have’ textbook for thousands of medical students, doctors, and health professionals across the world, describing the pathophysiology and clinical features of the most important conditions encountered in the major specialties of adult medicine and explaining how to investigate, diagnose and manage them. The book is the winner of numerous prizes and awards and has been translated into many languages. Taking its origins from Sir Stanley Davidson’s much-admired lecture notes, the book has endured because it continues to keep pace with how modern medicine is taught and to provide a wealth of information in an easy-to-read, concise, and beautifully illustrated format.

Davidson’s strives to ensure that readers can not only recognize the clinical features of a disease but also understand the underlying causes. To achieve this, each chapter begins with a summary of the relevant pre-clinical science, linking pathophysiology with clinical presentation and treatment so that students can use the book from the outset of their medical studies right through to their final examinations and beyond.

The regular introduction of new authors and editors is important for maintaining freshness. On this occasion, 21 new authors have joined our existing contributors to make up an outstanding team of authorities in their respective fields. As well as recruiting authors from around the globe, particularly for topics such as infectious diseases, HIV and envenomation, we welcome members from 10 countries on to our International Advisory Board. These leading experts provide detailed comments that are crucial to our revision of each new edition. A particularly important aspect in planning the revision is for the editors to meet students and faculty in medical schools in those countries where the book is most widely read so that we can respond to the feedback of our global readership and their tutors. We use this feedback, along with the information we gather via detailed student reviews and surveys, to craft each edition. The authors, editors, and publishing team aim to ensure that readers all over the world are best served by a book that integrates medical science with clinical medicine to convey key knowledge and practical advice in an accessible and readable format. The amount of detail is tailored to the needs of medical students working towards their final examinations, as well as candidates preparing for Membership of the Royal Colleges of Physicians (MRCP) or its equivalent.

With this new edition, we have introduced several changes in both structure and content. The opening six chapters provide an account of the principles of genetics, immunology, infectious diseases, and population health, along with a discussion of the core principles behind clinical decision-making and good prescribing. Subsequent chapters discuss medical emergencies in poisoning, envenomation, and environmental medicine, while a new chapter explores common presentations in acute medicine, as well as the recognition and management of the critically ill. The disease-specific chapters that follow cover the major medical specialties, each one thoroughly revised and updated to ensure that readers have access to the ‘cutting edge’ of medical knowledge and practice. Two new chapters on maternal and adolescent/transition medicine now complement the one on aging and disease, addressing particular problems encountered at key stages of patients’ lives. Medical ophthalmology is also now included as a direct response to readers’ requests.

The innovations introduced in recent editions have been maintained and, in many cases, developed. The highly popular ‘Clinical Examination’ overviews have been extended to the biochemistry, nutrition, and dermatology chapters. The ‘Presenting Problems’ sections continue to provide an invaluable overview of the most common presentations in each disease area. The ‘Emergency’ and ‘Practice Point’ boxes have been retained along with the ‘In Old Age’, ‘In Pregnancy’ and ‘In Adolescence’ boxes, which emphasize key practical points in the presentation and management of the elderly, women with medical disorders who are pregnant or planning pregnancy, and teenagers transitioning between pediatric and adult services.

Education is achieved by assimilating information from many sources and readers of this book can enhance their learning experience by using several complementary resources. We are delighted to have a new self-testing companion book entitled Davidson’s Assessment in Medicine, containing over 1250 multiple choice questions specifically tailored to the contents of Davidson’s. The long-standing association of Davidson’s with its sister books, Macleod’s Clinical Examination (now in its 14th Edition) and Principles and Practice of Surgery (7th Edition), still holds good. Our ‘family’ has also expanded with the publication of Davidson’s Essentials of Medicine, a long-requested pocket-sized version of the main text;  Davidson’s 100 Clinical Cases, which contains scenarios directly based on our ‘Presenting Problems’; and Macleod’s Clinical Diagnosis, which describes a systematic approach to the differential diagnosis of symptoms and signs. We congratulate the editors and authors of these books for continuing the tradition of easily digested and expertly illustrated texts.

We all take immense pride in continuing the great tradition first established by Sir Stanley Davidson and in producing an outstanding book for the next generation of doctors.
