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.

Anticoagulation management requires balancing multiple factors such as bleeding risk, thromboembolic risk, drug interactions, and renal function. Deep learning can assist in risk prediction, but its effectiveness relies on clinicians' ability to understand and verify the recommendations. Black-box models may recommend actions without providing clear explanations. In contrast, clinical guidelines are rule-based but not directly executable by neural models. This article introduces a neuro-symbolic XAI framework that combines deep learning predictions with explicit clinical guidelines. It includes a neural prediction module, a symbolic reasoning engine, and an integration layer for traceable justifications. The neuro-symbolic approach connects data-driven predictions to clinical rules, improving auditability and trustworthiness in decision support. This framework aims to enhance anticoagulation management by providing verifiable, clinician-understandable decision support, focusing on explainability-by-design.

Clinical triage algorithms increasingly influence access to emergency care, specialty referral, admission, and follow-up. As patient populations and clinical practice patterns change, these systems can silently drift toward biased performance. Current fairness assessments are often retrospective, episodic, and disconnected from operational triage workflows. They may identify inequity after harm has already accumulated rather than detecting emerging bias as it develops. This article proposes an explainable AI model for continuous monitoring of algorithmic bias in clinical triage systems. The model focuses on demographic drift, outcome disparities, prediction confidence, and referral decision patterns as complementary bias signals. The proposed model uses operational triage logs, demographic distributions, prediction outputs, outcome indicators, and referral decisions to generate a conceptual fairness risk signal. SHAP-based explanation modules decompose the signal into interpretable contributors for clinical governance teams. Conceptually, the model would detect divergence in referral patterns across demographic groups, identify whether the divergence coincides with demographic drift, flag subgroup-specific prediction confidence concerns, and explain the likely drivers of the alert. The output would support timely review rather than automated punitive action. The model could transform algorithmic fairness from a periodic retrospective report into a continuous, transparent, and operationally actionable surveillance system. It is designed as a governance-oriented framework rather than an experimental performance claim.

Many patients discharged from emergency departments require timely outpatient follow-up to complete diagnostic, therapeutic, or monitoring plans. When follow-up is delayed, unresolved symptoms, missed diagnoses, medication problems, and preventable return visits may occur. Current discharge workflows often rely on generic instructions and assume that patients can understand, schedule, and attend recommended care. Existing prediction approaches do not consistently combine unstructured discharge instructions, appointment access, portal engagement, social risk, and visit severity in a transparent way.This article proposes a transparent machine learning framework for predicting delayed follow-up after emergency department visits. The objective is to support patient-specific discharge planning by identifying both the likelihood of delay and the most actionable contributing barriers. The proposed model would combine structured emergency department and scheduling data with natural language processing features extracted from discharge instructions. A gradient-boosted tree model with SHAP-based explanations would provide patient-level and population-level interpretability. Conceptually, the model would identify patients at elevated risk of delayed follow-up and attribute that risk to factors such as unclear instructions, limited appointment availability, absent portal engagement, transportation barriers, or higher visit complexity. These explanations would be intended to guide targeted interventions rather than replace clinical judgment. A transparent model for delayed follow-up prediction could enable precision transitional care after emergency department discharge. By aligning predictions with actionable explanations, care teams could direct limited resources toward the specific barrier most likely to prevent timely follow-up.
