| Popis: | Purpose Quantify and examine the racial fairness of two widely used childhood asthma predictive precision medicine algorithms: the asthma predictive index (API) and the pediatric asthma risk score (PARS). Design Apply the API and PARS and evaluate model performance overall and when stratified by race. Setting Cincinnati, OH, USA. Subjects A prospective birth cohort of 590 children with clinically measured asthma diagnosis by age seven. Measures Model diagnostic criteria included sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Analysis Significant differences in model performance between Black and white children were considered to be present if the P-value associated with a t-test based on 100 bootstrap replications was less than .05. Results Compared to predictions for white children, predictions for Black children using the PARS had a higher sensitivity (.88 vs .57), lower specificity (.55 vs .83), higher PPV (.42 vs .33), but a similar NPV (.93 vs .93). Within the API and compared to predictions for white children, predictions for Black children had a higher sensitivity (.63 vs .53), similar specificity (.81 vs .80), higher PPV (.54 vs .28), and lower NPV (.86 vs .92). Conclusions Overall, racial disparities in model diagnostic criteria were greatest for sensitivity and specificity in the PARS, but racial disparities existed in three of the four criteria for both the PARS and the API. |
