Abstract

The ninth edition of this best-selling textbook of clinical medicine builds even further on its formidable, prize-winning formula of excellence, comprehensiveness and accessibility.

‘This book is stunning in its breadth and ease-of-use. It still remains the "gold standard", thorough guide to clinical medicine its forefathers were.’ BMA Medical Book Awards judges.

New to this edition:

  • 2 new chapters: Global Health and Women’s Health.
  • 25 new authors.
  • New online editor, Adam Feather, with a team of young doctors to augment the e-book which accompanies the print book with clinical tips, key learning points, drug tips, learning challenges, case studies and MCQs.
  • Full text redesign to incorporate:

New system overview diagrams for clinical chapters.

New coloured headings to help identify content relating to disease, management, investigations etc.

New icons to aid text navigation.

11 new members and a new co-editor, Senaka Rajapakse, of the International Advisory Board.

Edited by Kumar and Clark, clinicians and educators of world-renowned expertise.

Authors comprise consultants at the top of their fields, paired with younger doctors closer to the exam experience, to ensure authority and relevance.

Enhanced e-book accompanies the print book, for ease of transportation and use on the move.

International Advisory Board, led by Professor Janaka de Silva and Professor Senaka Rajapakse, providing guidance for global coverage from across the world.

Contributions to the e-book by members of the International Advisory Board to amplify areas of clinical importance in their parts of the world
