TLhis book sets out screening approaches in a quantitative manner and will enable choices to be based on objective evidence of efficacy and , where appropriate, safety.

In this book, there is no such assumption that new tests or technical procedures are useful. They are only considered as a legitimate medical option if they can and have been shown to lead to improvements in outcome.
