Table 3.

Frequency of record access events (RAEs) from the 10.5 million RAEs matching each of the baseline patterns for suspicious access

Baseline method pattern	Frequency
Accessing a coworker's record	975
Accessing a VIP patient's record	1487
Accessing the record of a patient with no recent visit	1738
Accessing a family member's record	9202
Researcher accessing over 200 records in a day	12 439
Accessing a neighbor's record	58 152
Accessing the record of a patient who did not have a medical record number at the user's site*	1 097 496

^*The large number of RAEs in this row is an artifact of the workflows and organizational structures at this integrated delivery network. For example, over 400 000 of these RAEs are accesses by resident physicians who are employees of the integrated delivery network and not of any clinical site.
