Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide, accounting for 25–30% of deaths, particularly in low-resource settings, and early identification of high-risk patients during labor could enable timely interventions such as uterotonic administration, blood preparation, and escalation of care; however, current risk stratification models rely mainly on static antepartum factors and fail to incorporate dynamic intrapartum physiological changes. Existing tools, including those from the California Maternal Quality Care Collaborative, use baseline maternal characteristics such as prior PPH, BMI, parity, and comorbidities, but do not capture continuously evolving labor data, despite intrapartum signals like fetal heart rate patterns, maternal vital sign trends, and labor progression metrics containing rich predictive information that remains underused in real-time decision-making, while clinical judgment is limited by inter-observer variability and inability to integrate complex temporal trends. To address this gap, we propose an explainable gradient boosting machine framework for real-time PPH risk prediction that integrates electronic fetal monitoring parameters (baseline rate, variability, decelerations), maternal vital signs (heart rate, blood pressure, temperature, oxygen saturation), and labor progression features (cervical dilation, contraction frequency, stage duration, and oxytocin use), producing continuously updated risk scores throughout labor. The system combines a gradient boosting model (XGBoost or LightGBM), a SHAP-based explainability module, a real-time feature extraction pipeline, and a clinician-facing dashboard that displays risk scores and key contributing factors, where SHAP provides both global and patient-specific interpretability by identifying how features such as tachysystole or prolonged labor stages influence predictions, thereby improving transparency and clinical trust. Overall, this framework enables dynamic, interpretable PPH risk assessment using routinely collected intrapartum data, combining predictive accuracy with explainability to support earlier detection of hemorrhage risk and more timely, targeted interventions.

Claim denials represent a major source of lost or delayed healthcare revenue. They are commonly driven by documentation gaps, coding inconsistencies, payer rule violations, and missing or invalid prior authorizations. Current denial prevention often depends on manual review and deterministic claim-scrubbing rules. These approaches may not capture complex payer-specific interactions among documentation quality, procedure codes, diagnosis codes, and authorization history. This article proposes an explainable gradient boosting model for estimating the probability that a health insurance claim could be denied before submission. The model is intended to identify the specific claim-level factors contributing to denial risk. The proposed framework uses a gradient-boosted tree ensemble trained conceptually on historical claims and remittance data. SHAP-based explanations would provide both global and local interpretability for denial-risk predictions. Conceptually, the model would return a denial risk score alongside an explanation of contributing factors such as incomplete documentation, diagnosis-code mismatch, expired authorization, or payer rule conflict. These outputs would support targeted pre-billing review rather than broad manual auditing. An explainable denial prediction model could help shift revenue cycle management from reactive appeals toward proactive prevention. Transparent reasoning would be essential for revenue cycle staff, clinical documentation teams, coders, and compliance stakeholders.
