Specialty referral pathways are a critical point at which healthcare inequities can emerge. Referral decisions may be shaped by insurance status, race, language, documentation practices, diagnosis severity, and the structure of available provider networks. Health systems often lack scalable and explainable tools for detecting inequitable referral patterns as they occur. As a result, discriminatory or structurally biased patterns may remain hidden within routine clinical operations. This article develops a conceptual explainable artificial intelligence model for identifying whether demographic or insurance factors unduly influence specialty referral decisions after accounting for clinical severity. The model is designed to support transparent, fairness-oriented referral analytics rather than replace clinical judgment. The proposed model uses a gradient-boosted classification framework trained on referral-eligible primary care encounters. Input features include patient demographics, insurance type, diagnosis severity, primary care note-derived complexity and completeness features, and provider network metrics, with SHAP-based explanation layers used for fairness auditing. Conceptually, the model could flag encounters in which predicted referral likelihood diverges from clinically expected patterns. These flags would be interpreted through explanation methods that attribute potential inequitable influence to insurance, demographic, documentation, or network-related factors. The model could help health systems audit, explain, and intervene on systemic specialty referral bias. Its central contribution is a transparent framework for moving referral equity work from retrospective description toward proactive, data-driven fairness review.

Failure to follow up after abnormal screening results is a persistent ambulatory safety problem. Because the diagnostic process often spans patient notification, scheduling, primary care review, and reminder outreach, delays may emerge gradually before they become visible in registry reports. Existing care gap reports commonly classify results as closed or open after a defined time window. This retrospective framing limits the ability to detect patients who are currently moving toward delayed diagnostic resolution. The objective of this article is to describe a predictive model that estimates the probability of delayed diagnostic follow-up after an abnormal screening result. The proposed model integrates patient engagement signals, scheduling activity, clinician workload, result severity, and reminder history. The model would use a gradient-boosted classification framework trained on historical abnormal results and longitudinal care-process features. Inputs would be extracted from patient portals, scheduling systems, primary care workload records, laboratory and radiology result metadata, and reminder logs. Conceptually, the model would generate a daily updated risk score for each unreconciled abnormal result. It would also identify the dominant drivers of risk, such as unread portal messages, repeated appointment cancellations, limited primary care availability, high-severity findings, or escalating reminder activity. A predictive approach could shift delayed follow-up management from retrospective audit to proactive prioritization. By identifying patients at greatest risk before the diagnostic window closes, care teams could better allocate outreach and navigation resources.

Preventive care delivery remains inconsistent despite well-established recommendations for cancer screening, immunization, and chronic disease monitoring. Missed preventive services create avoidable downstream morbidity, delayed diagnosis, and inefficient use of primary care resources. Current preventive care gap closure strategies are often reactive, fragmented, and dependent on manual review. Primary care clinicians cannot feasibly reconstruct every patient’s eligibility status, prior reminders, portal behavior, and visit timing during brief encounters. This article proposes an artificial intelligence system that continuously analyzes primary care records, applies screening eligibility rules, integrates reminder logs and patient portal activity, and detects upcoming visit opportunity windows. The system would surface a personalized preventive care gap list before or during clinical contact. The framework includes a rules engine for guideline-based eligibility, an engagement module that interprets reminder history and portal behavior, a visit opportunity detector, and a prioritization engine. Together, these components would rank preventive actions by clinical relevance, timing feasibility, and patient readiness. The system would transform routine primary care encounters into targeted preventive care opportunities by delivering the right recommendation at the right moment. By combining eligibility logic with engagement and visit context, it could support proactive care without relying solely on clinician memory. A proactive, AI-enhanced preventive care system could narrow the gap between evidence-based recommendations and real-world delivery. Its value would depend on transparent rule design, workflow-sensitive implementation, and careful prospective evaluation.
