The implementation of evidence-based practice is increasingly vital for healthcare professionals. The What is...? series explains the key concepts in a clear, concise and accessible format.

The short, practical bulletins provide a fresh slant on evidence-based medicine and the ideas behind it. All the publications in the series (listed above) have been written by respected figures from various NHS backgrounds.

The ongoing NHS reforms have resulted in greater emphasis on value for money and fuelled the growth of health economics and its related terminology. This series provides invaluable help for managers at all levels in their increasing involvement in policy discussions on, and analysis of, the cost-effectiveness of clinicial practice.
