In many cases it is difficult to apply cost-effectiveness analysis since the health effects are difficult to express in a single effectiveness unit. Apart from affecting survival, a treatment may for instance also affect the health status, which means that the effects on health status will not be included if the gained life years are used as the effectiveness measure. A health care programme may also affect more than one type of event, making it difficult to use the number of avoided events as the effectiveness measure if the types of event are different, e.g. a treatment may reduce the risk of some disease but also increase the risk of some sort of side-effect.
