Why care trajectories need a relational map

A health record captures what is happening to one body, or one state of mind. It rarely captures what is happening between people while that body or mind changes.

The invisible network

A chronic condition reshapes the dynamic at home. Burnout shifts who on a team quietly picks up which tasks. A dementia trajectory reorders roles within a family, often faster than anyone can keep pace with. None of these shifts appear in the medical file — and yet they largely determine how the trajectory unfolds.

What a relational map adds

Layers doesn't just model one person's health state, but the field around it: who is carrying what, where tension is building, where a caregiver who was never the patient is at risk of burning out first.

For professionals, this means earlier visibility into where a trajectory is likely to stall — not because treatment is failing, but because the network around it can no longer hold.

This doesn't replace medical expertise. It's the context medical expertise needs in order to adjust in time.
