Causal inference method corrects bias in clinical prediction models

Researchers have developed a novel method to address bias in clinical prediction models that arises from differential diagnostic testing rates across patient groups. The approach utilizes a causal inference framework and a hidden Markov model to estimate a patient's diagnosis probability under a counterfactual scenario where their testing rate matches a reference group. This technique was validated on simulated data, showing improved calibration, and applied to electronic health records for chronic kidney disease prediction, where it corrected bias related to diabetes.
