A patient I had been following for six years came to see me in March. Blood pressure fine, blood work clean, no particular complaint. A twenty-minute consultation, goodbye, see you next year.

By September he was on sick leave for burnout.

Nothing in the March snapshot showed it. And yet, in between, there had been a reorganisation at work, two months of five-hour nights, a parent in hospital. Things that do not appear in blood work, and that people do not spontaneously tell their doctor when they come in “for the annual check”.

The problem is not the doctor, it is the gap

Family medicine works in snapshots. Each consultation is a sharp, dated, reliable image. The problem is not the quality of the image: it is that between two of them lie six months of life we know nothing about.

We are trained to read values. We are not given the means to read trajectories.

What measuring differently brings

Three things change when you follow a person continuously rather than in bursts:

You see it coming. A decline in sleep over three months is a signal. On its own it means little; repeated, it says something.
The conversation starts further along. The patient does not have to remember everything, or know what to bring up. The elements are already there.
The patient sees themselves. Perhaps the most important part. A curve going back up motivates more than advice repeated once again.

What the consultation cannot see, measurement captures. What measurement cannot understand, the doctor listens to.

And the limit

Measuring is not treating. A score makes no diagnosis, replaces no clinical examination, and says nothing about what a person is really going through. It simply points to where to look.

That is all we ask of it.
