Patient portals are underused for one of their most useful features — here's what most people skip

Studies of patient portal usage patterns consistently find that viewing lab results and appointment scheduling dominate actual use, while features like secure messaging with the care team, medication list review, and downloading a complete visit summary go substantially underused relative to how often they'd be clinically useful — particularly for patients seeing multiple specialists who don't automatically share records with each other.

The feature with a specific, documented care-coordination benefit that's most commonly overlooked is the downloadable or shareable visit summary and full record export — bringing a complete, accurate medication and problem list to a new specialist or a hospital visit has been associated in care-transition research with fewer medication errors and redundant testing compared to relying on the patient's memory or an outside provider's incomplete record.

For patients managing a chronic condition across multiple providers, actively using portal messaging to flag discrepancies between what different specialists have on file — rather than assuming each provider automatically sees the others' notes — closes a coordination gap that remains common even with electronic records, since most health systems still don't share data seamlessly across different providers' separate EHR platforms.
