Undiagnosed dementia risk score

health-records improve undiagnosed dementia risk score in humans (c-statistic 0.801 (95% CI 0.799, 0.804)).

“with a small added benefit from incorporating new claims-based predictors (0.801 [0.799; 0.804]).”

machine-learning improves undiagnosed dementia risk score in humans (c-statistic 0.795 (95% CI 0.792, 0.798)).

“and was improved by refitting the model (0.795 [0.792, 0.798])”

health-records predict undiagnosed dementia risk score in humans (c-statistic 0.770 (95% CI 0.767, 0.773)).

“Model discrimination was good when applying EHR-based coefficients to Medicare claims-based predictors (c-statistic [95% confidence interval]: 0.770 [0.767, 0.773])”
