Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
The use of life expectancy statistics assumes that all deaths are perceived as being equal, which is probably not true. An alternative approach would be to use something like the Load Model . Load is the average weight attributed to mortality and morbidity over a defined period. Death is treated as an event with negative consequences, incurred in the year following death. Deaths may be weighted equally, with a fixed negative weight such as −100, or differ according to the context of death. After death, Load is zero. Morbidity Load is attributed to states of illness, according to their perceived severity. When people are in full health, Load is zero (no morbidity). For an example life, the size of the morbidity component compared with the mortality component is higher in the Load model than in the QALY model. When comparing alternative outcomes over a shorter period, there are also substantial differences between the two models.
