Benefits, Problems, and Potential Improvements in a Nationwide Patient Portal: Cross-sectional Survey of Pharmacy Customers' Experiences.

Pharmacy customers reported more benefits than problems or potential improvements regarding the use of My Kanta. The service is useful for viewing health data and prescriptions and for renewing prescriptions. However, portal users would like to see more data and functions available in the portal and data searches to be made easier. These improvements could make the data and functions provided by the portal easier to view and use and hence promote patient engagement.
