Welcome to the OpenPredictor

Metric Opportunity Calculator

This tool is designed to help NHS provider organisations estimate potential savings from implementing OpenPredictor, specifically within joint replacement pathways.

It supports the case for AI-driven surgical risk stratification by modelling improvements in clinical efficiency and reductions in waiting list pressures.

Please note: the information you enter will remain confidential and will not be shared externally under any circumstances.

While the calculator focuses on key inputs provided through your responses, it draws on a broader, independently evaluated health economics model conducted by Swansea University Research, Engagement and Innovation Services.

Select your NHS Organisation:

Face-to-Face (F2F) POA Time (mins) (B3)

Hips (national joint registry) (B5)

Knees (national joint registry) (B6)

The NHS England Referral to Treatment (RTT) standard sets out that patients should commence consultant-led treatment within 18 weeks of referral. This target remains a nationally recognised measure of timely access to elective care and is central to monitoring waiting list performance and system recovery.

Using the information you have provided, we estimate it will take this long to recover to an average waiting time of no more than 18 weeks for all patients referred for total joint replacements.

How many total joint replacement operations does your organisation perform every year?

1,500

0 1,500 3,000

The calculator is set to a default of 30% of the T&O waiting list being total joint replacements, based on the national average. The slider can be adjusted if local figures are available.

Indicative Rate of Change – RTT Waiting List
This metric shows the monthly percentage increase or decrease in the RTT waiting list. A positive rate means the backlog is growing; a negative rate means it’s reducing. It’s a simple indicator used to track progress on elective recovery NHS UK
