Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on thebmj.com. Although a selection of rapid responses will be included online and in print as readers' letters, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window. Letters are indexed in PubMed.
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.
