Objective To describe the characteristics and online practices of patients and “care partners” who share explicit access to a patient portal account at a large integrated health system that implemented shared access functionality in 2003.
Materials and Methods Survey of 323 patients and 389 care partners at Geisinger Health System with linked information regarding access and use of patient portal functionality.
Results Few (0.4%) registered adult patient portal users shared access to their account. Patients varied in age (range: 18–102); more than half had a high school education or less (53.6%). Patient motivations for sharing access included: to help manage care (41.9%), for emergency reasons (29.7%), lack of technology experience (18.4%), or care partner request (10.0%).
