Absolute diagnostic accuracy may not be possible, particularly in the field of primary care, when management has to be on analysis of symptoms and on knowledge of the individual patient and family. This series follows that on Problems in Practice which was con cerned more with diagnosis in the widest sense and this series deals more definitively with general care and specific treatment of symp toms and diseases.

They find it difficult to remain up-to-date with medical advances and even more difficult to decide on the suitability and application of new and relatively untried methods compared with those that are 'old' and well proven. Their advantages are that because of long-term continuous care for their patients they have come to know them and their families FOREWORD well and are able to become familiar with the more common and less serious diseases of their communities.
