Frailty algorithm

The Discovery Data Service helps to identify potentially frail patients using a frailty algorithm.

The frailty algorithm results can be provided via the NHS 111 Discovery frailty flagging API or displayed in the Frailty Checker.

If the specified patient has an observation for severe or moderate frailty, the algorithm returns a value of true; observations for mild frailty return a value of false. If a patient is not found in the Discovery Data Service, the algorithm returns a value of not found.

The frailty algorithm results are then described, via the API or in the Frailty Checker, as follows:

Potentially frail - Patient has Moderate or Severe frailty codes

            Not frail - Patient has Mild or No frailty codes

            Not found - Patient not found

           

The frailty algorithm uses the following frailty codes:
