With increasing pressure on national healthcare budgets, there has evolved in recent years a greater appreciation of the costs of medical interventions. This has resulted in the burgeoning field of health ecomics in which the costs versus benefits of various medical treatments are compared against desired incomes. Bridging a gap in the literature, this new book introduces and comprehensively covers the subject of health ecomics. Section 1 explains in detail the principles and theory of health ecomics using examples relevant to pharmacy. Section 2 moves on to discuss ecomic evaluation methodology and contains many work examples. Each chapter is fully referenced and contains a bibliography and suggestions for further reading.
