Objective:
The authors examined the mortality rate in geriatric patients receiving either haloperidol or atypical antipsychotics.
Methods:
Authors tracked mortality over a 2-year period in patients age 65 years or older receiving haloperidol (N=299) or the atypical antipsychotics risperidone or olanzapine (N= 1,254).
Results:
Sixty-four patients in the haloperidol group (21.4%) and 61 patients in the atypical group (4.75%) died during the 2-year study period. The difference was statistically significant.
Conclusions:
The findings suggest that mortality in elderly patients receiving haloperidol is significantly higher than in those receiving the atypical antipsychotics risperidone or olanzapine. Authors discuss possible causal mechanisms.
