The evolution of patient engagement in patient-centered care has led to the development of online personal health record (PHR) systems, which are accessed through use of a patient portal. Researchers have found that older adults are among those yet to adopt its use. The UTAUT2 factors are used to help understand an individual's intention to use technology and help explain older adults' perception of information technology and their intention to use a patient portal for engagement in their healthcare. The problem addressed by this study is older adults' non-use of patient portals for engagement in their healthcare. The purpose of this qualitative study was to explore older adults' perceptions of the UTAUT2 factors related to intention to use a patient portal for engagement in their healthcare. Face-to-face interviews were conducted with a final sample of 15 older adults from 2 senior centers and 2 residential service agencies. The themes included (a) Monitoring Health, (b) Refresh memory, (c) Research, (d) Interaction at health facility, (e) Associated to Healthcare, (f) Knowledge, (g) Saving time and money, and (h) No transportation needed. Recommendations for practice include (a) the provision of adequate training to help older adults explore the capabilities of a patient portal in monitoring health will help support and aid in the management of their health; (b) caregivers at health care facilities to use their influence to interact and help older adults navigate a patient portal; (c) caregivers including physicians to develop frequent correspondence with older adults through the patient portal.
