Design outcomes

Primary

MeasureTime frameDescription
Number of Participants with Stroke as a Principal Inpatient DiagnosisUp to 16 years (from 01-January-2002 through 31-December-2017)Number of participants with stroke in each target cohort versus comparator cohort (aged 65 years and older) per person years at risk will be reported. It is defined defined by the presence of the relevant ICD codes (ICD-9 or ICD-10 according to date) in the inpatient setting as the primary diagnoses.

Secondary

MeasureTime frameDescription
Number of Participants at Stroke Risk when Compared Among New Users of Typical Antipsychotics/Haloperidol versus Atypical AntipsychoticsUp to 16 years (from 01-January-2002 through 31-December-2017)The number of participants with the risk of stroke among participants exposed to typical antipsychotics versus atypical antipsychotics will be reported.
