Statistical Issues in the Diagnosis of Shaken Baby Syndrome/Abusive Head Trauma

The diagnosis of Shaken Baby Syndrome/Abusive Head Trauma (SBS/AHT) is fraught with controversy due to critical statistical deficiencies in the data underpinning these diagnoses. This paper examines the reliability and scientific foundation of SBS/AHT through a statistical lens, highlighting the lack of independently verified ground truth, contextual biases, data circularity, and diagnostic heterogeneity. These issues render current methodologies inadequate and complicate evaluations of diagnostic accuracy, particularly when legal determinations are integrated into medical assessments. Without empirical evidence validating the specificity of symptoms like subdural hematoma, retinal hemorrhage, and brain swelling, the diagnosis remains untested and its foundational validity unproven. We recommend that physicians focus on reporting observed clinical signs and avoid making determinations of abuse, which should remain within the legal domain. Addressing these challenges requires comprehensive, high-quality data collection encompassing contextual, medical, and legal information to evaluate the accuracy, repeatability, and reproducibility of SBS/AHT diagnoses. These efforts are essential to protect vulnerable children while ensuring fairness and accuracy in legal proceedings involving allegations of abuse.
