1. Study identification
EU PAS Register NumberEUPAS6539
Official titlePharmacoepidemiological Safety Study of Neuroleptics and Antidepressants in the Area of Geriatric Psychiatrics.
Study title acronymPhaSiNAg
Study typeObservational study
Brief description of the studyThe use of neuroleptics and antidepressants in elderly patients has been associated with adverse drug reactions such as cerebrovascular and cardiovascular events, pneumonia, fractures, venous thromboembolism and higher all-cause mortality. Based on data from the German Pharmacoepidemiological Research Database (GePaRD), the PhaSINAg project will investigate the safety profiles of neuroleptics and antidepressants in elderly patients in consideration of co-morbidity and co-medication.. Furthermore, prescription patterns of neuroleptics and antidepressants in patients aged 65 years and older will be analyzed. Within this context, investigations on how previous risk minimization activities led to changes in prescription patterns and how administrative data may be used for systematic risk monitoring will be conducted.

Risk assessment
Drug utilisation study
Primary scope : Risk assessment
12. Main objective(s)
What is the main objective of the study?
To estimate the risk of acute myocardial infarction, heart failure, ventricular arrhythmia, ischemic stroke, hip fracture and all-cause mortality for incident users of NLs and ADs aged 65 years and older and to compare these risks between individual drugs and drug classes. For incident NL users, the outcomes pneumonia and venous thromboembolism will also be investigated.
Are there primary outcomes?Yes
Acute myocardial infarction, heart failure, ventricular arrhythmia, ischemic stroke, hip fracture, pneumonia, venous thromboembolism and all-cause mortality.
Are there secondary outcomes?No
13. Study design
What is the design of the study?
Cohort study
Drug utilisation study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Follow-up in the primary analysis will be from first dispensation of a neuroleptic or antidepressant until the first of the following dates: interruption of the insurance status for more than 3 days or end of insurance (incl. death), end of study period, i.e. December 31st, 2011, 180 days after cohort entry or occurrence of outcome.
15. Data analysis plan
Please provide a brief summary of the analysis method
For the primary and secondary analysis, Cox models will be used to estimate the adjusted hazard ratio for each outcome in the NL (reference group: atypical neuroleptic) and antidepressant (reference group: tri- and tetracyclic antidepressants) drug classes and for frequently used individual drugs (reference group neuroleptic: risperidone, reference group antidepressants: citalopram). The time-scale for the time-to-event analysis is the time in the cohort until occurrence of an outcome or censoring at the end of cohort time. Pre-defined a priori covariates such as age, sex, and prior history of selected co-morbidity and co-medication will always be included in the model. A backward selection (p=0.05) will be performed to include additional covariates in the model.
