Laboratory alert fatigue erodes the effectiveness of clinical decision support by making repeated abnormal result notifications less likely to prompt timely clinical attention. It is often recognised only after providers begin delaying, overriding, or ignoring alerts. Current alert reduction strategies are commonly based on broad thresholds or blanket suppression rules. These approaches do not explain which providers, specialties, alert types, or repeated result patterns are most susceptible to fatigue. This article proposes an interpretable machine learning model that could predict whether a provider will exhibit fatigued behaviour toward a specific laboratory alert. The model is intended to support transparent, provider-aware alert redesign rather than opaque automation. The proposed framework would use historical alert logs with features capturing alert frequency, clinical severity, provider specialty, repeated abnormal results, response time history, and override behaviour. A regularised logistic regression or gradient-boosted tree model with SHAP explanations would provide both prediction and interpretability. Conceptually, the model would generate a fatigue risk score for each provider–alert pair. It would also attribute the score to specific drivers, such as repeated low-severity results, accumulated alert burden, or recent override patterns. An interpretable fatigue prediction model could enable personalised alert suppression, escalation, or redesign before a clinically important laboratory result is missed. Such a system would support safer, more adaptive clinical decision support.

Clinical pathways are designed to standardize inpatient care for common conditions while allowing clinically justified individualization. Deviations from these pathways are frequent and may reflect either appropriate adaptation to patient complexity or potentially harmful departure from evidence-informed practice. Current deviation detection often depends on retrospective audit, static compliance rules, or aggregate dashboards. These approaches can miss subtle temporal drift in care delivery and rarely explain why a specific patient trajectory diverged from the expected pathway. This article proposes an interpretable machine learning model for detecting clinical pathway deviations in hospitalized patients. The model focuses on order sequences, vital sign trends, laboratory monitoring frequency, and provider decision patterns as dynamic indicators of care-process variation. Conceptually, the model would compare each patient’s evolving care trajectory with learned expected pathways using sequence-comparison and outlier-detection logic. SHAP-based or attention-informed explanations would identify the specific features responsible for a deviation flag, such as delayed monitoring, omitted follow-up testing, or unusual ordering behavior. The proposed model could detect when a patient’s care trajectory diverges from an expected pathway and provide a transparent rationale for review. For example, it could flag a missing repeat troponin, a delayed antibiotic escalation, or a laboratory monitoring pattern inconsistent with the patient’s clinical state. An interpretable pathway-deviation model could shift quality monitoring from manual, sample-based review toward continuous and transparent pathway surveillance. Such a system would support real-time clinical awareness, structured audit, and organizational learning.

Prior authorization delays impede timely patient care and contribute to administrative pressure across clinical and revenue cycle workflows. These delays can affect scheduling, medication access, procedural planning, and patient confidence in the care process. Current authorization management tools are largely reactive and often focus on tracking request status after submission. They rarely predict which requests are likely to experience approval delays or explain the operational, clinical, or payer-specific reasons behind those delays. This article proposes an interpretable machine learning model for predicting the likelihood of prior authorization approval delays. The model is designed to provide transparent, request-level explanations that can guide pre-submission correction and authorization preparation. The proposed framework uses a gradient-boosted tree model trained conceptually on historical authorization requests. Inputs include payer-specific rules, clinical documentation features, procedure type, medical necessity indicators, and historical approval timelines, with SHAP used to attribute predicted delay risk to individual features. Conceptually, the model would output a delay probability and an explanation of the dominant drivers of that prediction. These drivers could include incomplete documentation, mismatch with payer medical necessity criteria, procedure categories associated with additional review, or payer-procedure combinations with historically slow turnaround. An interpretable prior authorization delay model could support earlier correction of incomplete requests, reduce administrative waste, and improve patient access. By aligning predictive analytics with transparent explanations, the framework could make authorization preparation more proactive and accountable.
