The aim of our study was to characterize emergency department clinicians’ health information exchange (HIE) use patterns after the implementation of a Fast Healthcare Interoperability Resources (FHIR) application. Using longitudinal electronic health record log data, we categorized HIE use behavior as: no HIE use (0), Web-based viewer use only (1), FHIR application use only (2), or Web-based viewer and FHIR application use (3). We sequenced HIE use behavior from September 2019 to February 2023, then employed hierarchical agglomerative clustering to identify clinician characteristics associated with each HIE use pattern. Our results indicated the presence of four patterns representing (1) clinicians who “lag” in HIE use and continue as sporadic HIE users (n=66, 46.1%), (2) “late adopters” who have more consistent usage over time (n=32, 22.4%), (3) “legacy users” whose preferred modality was CareWeb (n=25, 17.5%), and (4) “mixed modality users” who displayed frequent changes in HIE access modality (n=20, 14.0%).
