Patient portals store data.
They do not manage trends.
Most healthcare portals were built to share records, not to track what happens between visits.
What most portals do
- Show lab results
- Store visit notes
- Allow patient-provider messaging
What most portals do not do
- Collect structured daily symptom data
- Track trends across weeks or months
- Detect early deterioration
- Convert patient inputs into clinical summaries
Portals are archives.
Merina is an early-detection system.
A portal that shows your lab result from last month does not tell your doctor that your pain has been increasing every week since then.
A portal that stores your medication list does not tell your doctor that you have been missing doses three days a week.
These are the signals that matter most in chronic care. They live in the gap between visits. Today, that gap is empty.
