Importance of perspective in economic analyses of cancer screening decisions.
As the fifth, and final, report in this Lancet series on health economics, we discuss how economic analyses in public health, with cancer screening as the example, differ depending on the perspective taken. We identify nine different, but related, decision makers at various levels, from the individual patient to society as a whole, and discuss how their different viewpoints affect their ultimate decisions. Central to our discussion is the identification of seven distinct components of perspective, each potentially important in the screening decision. In many fields of healthcare, decisions about the use of resources, such as time, wealth, or energy, are made by weighing up the positive and negative consequences of the alternatives under consideration and are thus based on an economic analysis of the situation (although sometimes this process is subconscious). For simplicity, we restrict our report to the effect of perspective on cancer screening decisions and show how the costs (negative consequences) and benefits (positive consequences) vary depending on the decision maker.
