ABSTRACT
This chapter explains the changes with particular reference to the United Kingdom. The effects of legislation and the structure of healthcare delivery will differ from country to country. The effects of developments in medical science and changes in professional attitudes will be more widely applicable. The increase in breadth and depth of knowledge has resulted in increasing specialisation and sub-specialisation as medical science developed. In the nineteenth century it was still possible for the well-educated physician to have a sound knowledge of the whole of medical practice and its underpinning scientific foundations.
