O18 IBD care in 2020: results from the first IBD UK patient and service benchmarking tool

Abstract

With this model we stratified the cohort into high and low risk groups, which corresponded to an overall positive predictive value (PPV) 31%, and negative predictive value (NPV) 96% by year 5 of follow-up (p<0.0001). To test this stratification criteria, the model was then applied to the external validation cohort and accurately predicted risk groups in this set with PPV 29%, NPV 93% by year 5 of follow-up (p<0.001). The final validated model was embedded in a web-based tool to calculate and illustrate patient-specific risk (figure 1). Conclusions We have designed and externally validated www. UC-CaRE.uk, a personalised AN risk prediction webtool to facilitate shared decision-making over the management of LGD.
