The calculator's performance was analysed using the area under the receiver operating characteristic curve (AUC), the Hosmer\u2010Lemeshow test and the Brier score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We included 305 patients in the study. Mean age was 82.4 \u00b1\u20097.8\u2009years and 215 (70.5%) were female. The calculator performed well for predicting delirium (AUC 0.859, 95% CI 0.811\u20130.902, Brier score 0.150), functional decline (AUC 0.883, 95% CI 0.826\u20130.935, Brier score 0.120) and mortality (AUC 0.854, 95% CI 0.774\u20130.917, Brier score 0.065). Results from the Hosmer\u2010Lemeshow test for all of these outcomes demonstrated good calibration. The calculator had reduced performance in predicting discharge destination and pressure\u2010injury risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The calculator is a moderately reliable predictor of delirium, functional decline and inpatient mortality in older patients who undergo hip fracture surgery.
