No diseases for old men
Antibiotics are routinely used to extend the lives of people with severe dementia but is that treatment really in the patient's best interest? Peter Singer

Pneumonia used to be called "the old man's friend" because it often brought a fairly swift and painless end to a life that was already of poor quality and would otherwise have continued to decline. Now a study of severely demented patients in Boston-area nursing homes shows that the "friend" is often being fought with antibiotics. Such practices raise the obvious question: are we routinely treating illnesses because we can, rather than because we ought to?
The study, carried out by Erika D'Agata and Susan Mitchell and recently published in the Archives of Internal Medicine, showed that over 18 months, two-thirds of 214 severely demented patients were treated with antibiotics. The mean age of these patients was 85. On the test for severe impairment, where scores can range from zero to 24, three-quarters of these patients scored zero. Their ability to communicate verbally ranged from non-existent to minimal.
It isn't clear that using antibiotics in these circumstances prolongs life, but even if it did, one would have to ask: what is the point? How many people want their lives to be prolonged if they are incontinent, need to be fed by others, can no longer walk, and their mental capacities have irreversibly deteriorated so that they can neither speak nor recognise their children? In many cases, the antibiotics were administered intravenously, which can cause discomfort.
The interests of patients should come first, but when it is dubious that continued treatment is in a patient's interests and there is no way to find out what the patient wants, or would have wanted, it is reasonable to consider other factors, including the views of the family and the cost to the community. In America, medicare costs for beneficiaries with Alzheimer's disease were $91 billion in 2005, and are expected to increase to $160 billion by 2010. (For comparison, in 2005 the US spent $27bn on foreign aid.)
Moreover, D'Agata and Mitchell suggest that the use of so many antibiotics by patients with dementia carries a different kind of cost: it exacerbates the growing problem of antibiotic-resistant bacteria, putting other patients at risk. .....(more)
