This article examines the impact of mental health services on the mort
ality rate for mentally ill nursing home residents. Previous research
has documented the unmet need for mental health services among nursing
home residents. Some research using small data sets has indicated pat
ient benefits from treatment. This article examines the issue using da
ta from the nationally representative National Nursing Home Survey. In
a series of multivariate logistic regressions, treatment for mental i
llness provided by either general practice physicians or by mental hea
lth specialists appears to have few impacts on mortality. A statistica
lly significant treatment effect is found only for residents with schi
zophrenia, other psychoses, or anxiety disorders when treated by menta
l health specialists. The results are discussed with reference to ongo
ing reforms for mental health care in nursing homes.
