To the Editor: Drs Morrison and Siu1 concluded that patients with advanced dementia
and pneumonia had a higher 6-month mortality rate than cognitively intact
patients. In this sample, patients with dementia were more likely to reside
in nursing homes than cognitively intact patients. However, pneumonia in nursing
homes is quite a different disease than that seen in the community. Klebsiella pneumoniae and Staphylococcus
aureus are frequently isolated in nursing home patients, in contrast
to such pathogens as Streptococcus pneumoniae and Haemophilus influenzae that are more common in community-dwelling
patients.2,3 The mortality
due to pneumonia may be more than twice as high in nursing home patients (40%)
as in community patients (20%).2- 4
Therefore, the authors' results do not fully reflect the effect of dementia
on mortality due to pneumonia.
