Ethics approval and consent to participate
: The University of British Columbia’s behavioural research ethics board has approved the study. As the data linkage maintained patient anonymity (all identifiers were removed before being provided to the researchers) and the population-based administrative datasets in BC operate based on passive consent (i.e. patients may withdraw their consent and their data will be removed from the administrative datasets), direct patient consent was not required.
: Not applicable.
: The authors declare that they have no competing interests.
