Using health records to spot frail older patients
Original title: An electronic frailty index for population-level risk stratification in a large health maintenance organization: A cohort study
How far along is this research?
This is a preprint. Other scientists have not checked it yet, so treat it as an early signal rather than an answer.
This is a risk score tested on past patient records, not a treatment.
The short version
A score built from health records can show which older patients are most at risk.
What was studied. Researchers used health records from 641,748 people aged 65 and older in Israel. They built a frailty score, called CeFI, from a list of 36 health problems.
What they found. In one year, 0.9% of the people scored as fit died. Among the people scored as most frail, 18.7% died. The chance of going to the hospital or dying rose from 11.5% to 57.5%. The score was also tried in 702 people having brain surgery for a tumor.
What this means, and what it doesn't
What it could mean: Facts already in your medical record may show how frail you are. A care team could use a score like this before surgery. It may help you and your doctor talk honestly about risk.
What it doesn't mean: This is not a treatment and it is not a cure. The score only sorts people into risk groups. It cannot say what will happen to any one person. It was built by looking back at records in one health system in Israel. It is not part of everyday care yet.
