This study assessed the stability of nursing home residents' preferenc
es for medical treatments. Thirty-seven nondemented, nondepressed resi
dents were surveyed serially over a six-month period. Preferences were
elicited for CPR, IV antibiotics, mechanical ventilation, and artific
ial nutrition. Subjects preferred more treatment for their current hea
lth concerns than for all hypothetical conditions (p =.001). Subjects
disvalued indefinite artificial nutrition and mechanical ventilation c
ompared to time-limited trials (p <.001). All preference changes were
toward less intervention; residents preferred limited treatment. Most
preferences remained stable. Residents clearly distinguished between t
ime-limited and indefinite treatment, desired IV antibiotics and limit
ed mechanical ventilation, and rejected most other treatments.
