External Validation of the Passive Surveillance Stroke Severity Indicator

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2022
ABSTRACT:Background:The Passive Surveillance Stroke Severity (PaSSV) Indicator was derived to estimate stroke severity from variables in administrative datasets but has not been externally validated.Methods:We used linked administrative datasets to identify patients with first hospitalization for acute stroke between 2007-2018 in Alberta, Canada.
