The PROMPT (Practical Obstetric Multi-Professional Training) course covers the management of a range of obstetric emergency situations. Over the past five years, there has been increasing evidence that PROMPT training is having significant impact on outcomes in the UK, and internationally. In 2016, PROMPT was recognised in the NHS England: National Maternity Review. The PROMPT training package consists of interactive lectures, drills and workshops, providing hands-on experience of practical skills and team-working in simulated obstetric emergency situations. This third edition has been comprehensively updated in line with recent evidence and national and international guidelines to reflect the latest research and current clinical practice. There are new modules, algorithms, implementation tools, scenarios and videos. The course manual is essential reading for all those attending a local PROMPT course. It is also useful as a stand-alone textbook, providing evidence-based, up-to-date information for any health professional involved in maternity care.
