This book is based on the very popular international publication (Crezee, 2013) and has been supplemented with Spanish glossaries. Just like the 2013 textbook, this practical resource will allow interpreters and translators to quickly read up on healthcare settings, familiarizing themselves with anatomy, physiology, medical terminology and frequently encountered conditions, diagnostic tests and treatment options. It is a useful and easily accessible handbook, in particular for interpreters, translators, educators and other practitioners working between Spanish and English. A special chapter on the US insurance system adds even more value for those in the US. The extensive English-Spanish glossaries will be very useful to Spanish speaking practitioners, and may also be beneficial to those working with other Romance languages, as the Spanish terms may serve as a trigger to help identify cognates. Where terms are most commonly used in a particular part of the Spanish speaking world, an abbreviation has been added to indicate which country it may be found in. This helps ensure that terms reflect usage in different parts of the Americas, and also in Spain.
