Dimensions and definitions of knowledge brokering

No.	Dimensions	Definitions
1	Proactive versus reactive knowledge brokering	Proactive knowledge brokering occurs when a patient or care partner offers the information without being prompted by ED clinician or staff.
		Reactive knowledge brokering occurs when a clinician or staff asked/prompted the patient about some information.
2	Content of information	Content of information is about the information being communicated during knowledge brokering instances and includes the patient’s prior health conditions, medications, care after disposition from the ED, and diagnostic testing.
3	Within-ED work system and across across-system knowledge brokering	Within-ED work system knowledge brokering occurs when a patient or care partner acts as a knowledge broker among ED clinicians and/or staff (e.g., between ED nurse and ED resident).
		Across-system knowledge brokering occurs when a patient or care partner acts as a knowledge broker between the ED (i.e., ED clinicians and staff) and other care settings (e.g., neurology specialist, hospitalist, EMS, PCP, SNF, assisted living facility).
4	Anticipatory knowledge brokering	Anticipatory knowledge brokering occurs when knowledge brokering is recognized by a clinician or the patient and care partner for a future interaction (e.g., when an ED clinician or staff recommends that the patient or care partner brings up information to their PCP in a post-ED follow-up visit that will occur in the future).
