The second edition of the book “An Evidence-Based Clinical Textbook in Obstetrics and Gynaecology for MRCOG-2” has been primarily inspired by the success of the first edition. Similar to the previous edition, the second edition has also adopted an evidence-based approach, especially focussing on the current standards in health care. It helps in the amalgamation of clinical expertise, patient values, and the best research evidence so that it can be used in the decision-making process for patient care. The previous categorisation of the book into three parts: general, obstetrics, and gynaecology as well the pattern of previous sections have been retained in this comprehensive new edition. This new edition comprises of 98 chapters, distributed into 17 sections and is based as per the current MRCOG-2 curriculum available from the RCOG website. Nevertheless, there has been an addition of several new chapters such as thromboembolism in pregnancy, genetic disorders, postpartum collapse, Zika virus infection, etc. COVID-19 and its management during pregnancy has also been discussed at length in this new edition. Addition of online content is another new value-adding feature of this book. The book buyers would get access to more than 250 questions (in form of EMQs and SBAs), which have been added in an interactive format on an online portal. This additional content can be redeemed by using the scratch code going inside the front cover of the book. Besides a detailed explanation, which is provided with each question, an 8–9-hour-long video discussing these questions and other tips and tricks for clearing the Part 2 examination has also been added. The references of each chapter can also be accessed online by scanning a QR code. In case the reader wants to obtain more information related to a specific online reference, it can be clicked to access the actual journal article. This would also enable the reader to access the Green-Top Guidelines available online and read them in its entirety. The text in each chapter has been organised in the form of a predefined template, including headings such as introduction, aetiology/indications, diagnosis, differential diagnosis, management, complications, and evidence-based medicine. A new heading, titled ‘key features’, has been added to all the chapters in the new edition. This heading would help the reader in summarising the chapter. Important topics in each chapter have been delineated with help of a specific symbol so that the reader lays special emphasis on these topics. This style facilitates innovative learning and would enable the readers to quickly revise just before the examination by taking a glance at the key features and portions of the text indicated with an icon of a ‘pin’.
