Results: EHR systems “as-used” vary substantively from one family physician to another in terms of the
capabilities that are actually mobilized by them. Significant differences between “basic” and “advanced”
users were observed in terms of the EHR system’s characteristics and perceived performance outcomes.
Physicians were also clustered under three profiles that could be clearly distinguished from one another,
in terms of the extent to which their performance and their practice’s performance was impacted by their
EHR usage
