- AimThe aim of the study was to examine mortality risk associated with use of antidepressants and antipsychotics classified with torsades de pointes (TdP) risk in elderly. MethodsA matched case-control register study was conducted in people 65 years and older dying outside hospital from 2008-2013 (n=286092) and matched controls (n=1430460). The association between prescription of antidepressants and antipsychotics with various TdP risk according to CredibleMeds () and all-cause mortality was studied by multivariate conditional logistic regression adjusted for comorbidity and several other confounders. ResultsUse of antidepressants classified with known or possible TdP risk, was associated with higher adjusted risk for mortality (OR 1.53, 95% CI 1.51, 1.56 and OR 1.63, 95% CI 1.61, 1.67, respectively) compared with antidepressants classified with conditional TdP risk (OR 1.25, 95% CI 1.22, 1.28) or without TdP classification (OR 0.99, 95% CI 0.94, 1.05). Antipsychotics classified with known TdP risk were associated with higher risk (OR 4.57, 95% CI 4.37, 4.78) than antipsychotics with possible risk (OR 2.58, 95% CI 2.52, 2.64) or without TdP classification (OR 2.14, 95% CI 2.03, 2.65). The following risk ranking was observed for commonly used antidepressants: mirtazapine > citalopram > sertraline > amitriptyline and for antipsychotics: haloperidol > risperidone >olanzapine > quetiapine. ConclusionThe CredibleMeds system predicted drug-associated risk for mortality in the elderly at the risk class level. Among antipsychotics, haloperidol, and among antidepressants, mirtazapine and citalopram, were associated with the highest risks. The results suggest that the TdP risk with antidepressants and antipsychotics should be taken into consideration when prescribing to the elderly.

- ObjectiveTo investigate whether psychotropics are associated with an increased risk of fall injuries, hospitalizations, and mortality in a large general population of older adults.MethodsWe performed a nationwide matched (age, sex, and case event day) case–control study between 1 January and 31 December 2011 based on several Swedish registers (n = 1,288,875 persons aged ≥65 years). We used multivariate conditional logistic regression adjusted for education, number of inpatient days, Charlson co-morbidity index, dementia and number of other drugs.ResultsAntidepressants were the psychotropic most strongly related to fall injuries (ORadjusted: 1.42; 95% CI: 1.38–1.45) and antipsychotics to hospitalizations (ORadjusted: 1.22; 95% CI: 1.19–1.24) and death (ORadjusted: 2.10; 95% CI: 2.02–2.17). Number of psychotropics was associated with increased the risk of fall injuries, (4 psychotropics vs 0: ORadjusted: 1.53; 95% CI: 1.39–1.68), hospitalization (4 psychotropics vs 0: ORadjusted: 1.27; 95% CI: 1.22–1.33) and death (4 psychotropics vs 0: ORadjusted: 2.50; 95% CI: 2.33–2.69) in a dose–response manner. Among persons with dementia (n = 58,984), a dose–response relationship was found between number of psychotropics and mortality risk (4 psychotropics vs 0: ORadjusted: 1.99; 95% CI: 1.76–2.25).ConclusionsOur findings support a cautious prescribing of multiple psychotropic drugs to older patients. © 2016 The Authors.
