Patient access to timely, appropriate care remains a persistent challenge for health systems, affecting clinical continuity, patient experience, and operational performance. Artificial intelligence has been proposed as a means of automating and optimizing navigation functions from scheduling to follow-up coordination. This systematic review examined artificial intelligence applications for care navigation and patient access across scheduling optimization, referral management, eligibility screening, digital front-door tools, and follow-up coordination. The review also assessed implementation maturity, evaluation approaches, and equity-related reporting. A PRISMA 2020-compliant search was conducted across PubMed, Scopus, IEEE Xplore, and Web of Science for publications from 2017 through 2025. Dual screening, structured data extraction, risk-of-bias assessment, and narrative synthesis were used to characterize the evidence. The literature was concentrated in scheduling optimization, particularly no-show prediction and operational appointment management, and in digital front-door tools such as symptom checkers and triage chatbots. Referral and eligibility applications were emerging, while follow-up coordination models often overlapped with readmission and care-transition prediction. Few studies reported prospective implementation, comparative deployment outcomes, or equity impacts. Artificial intelligence-driven patient access tools appear technically robust for isolated tasks, but evidence that they improve integrated, end-to-end navigation remains limited. The field requires stronger prospective evaluation, equity assessment, and implementation reporting.

Hospital discharge delays are rooted in fragmented coordination across clinical, administrative, and logistical work. Discharge readiness depends on many interdependent tasks that must be completed in the correct sequence. No current system fully orchestrates discharge sub-tasks by reasoning across care plans, medication reconciliation, transport requests, follow-up scheduling, and pending orders in real time. Existing digital tools often support isolated functions rather than end-to-end coordination. This article proposes an agentic AI system that perceives discharge requirements, plans task sequences, executes coordination actions, and monitors completion under human supervision. The system is conceptual and should be understood as an emerging design pattern rather than an evaluated intervention. The proposed system includes a task decomposition engine, goal-oriented reasoning core, EHR data adapters, follow-up scheduling rules engine, transport request interfaces, and human override dashboard. These components would allow the agent to coordinate discharge logistics while preserving clinician authority. The system would function as a virtual discharge coordinator that continuously tracks task status and identifies stalled work. It could reduce idle coordination time, prevent overlooked tasks, and allow nurses and case managers to focus on higher-value clinical and relational work. Agentic AI could transform discharge management from a manual, interruption-prone process into an automated, accountable, and scalable workflow. Safe deployment would require interoperability, auditability, constrained autonomy, and rigorous evaluation.

Patient access performance—scheduling efficiency, referral completion, wait times, and appointment attendance—varies widely across healthcare organizations. These organizations rarely learn from each other because operational data are sensitive, locally governed, and often competitively protected. Isolated access analytics limit the discovery of generalizable patterns and prevent hospitals from learning from peer institutions with different patient populations and workflows. No current operational platform fully enables multi-hospital learning about patient access without exposing patient-level scheduling, referral, and attendance data. This article proposes a privacy-preserving AI platform that uses federated learning and secure aggregation to support cross-hospital modeling of scheduling demand, referral completion, appointment lead time, and no-show risk. Raw data remain within each participating hospital, while only protected model updates or aggregate statistics contribute to shared learning. The platform consists of local data adapters, standardized access-feature pipelines, a federated model trainer, a secure aggregation layer, differential privacy controls, and local operational dashboards. Each hospital receives a shared model that can be adapted locally while preserving institutional data control. The framework could enable hospitals to benefit from broader operational learning while maintaining confidentiality, competitive neutrality, and governance accountability. It would be expected to support more consistent access analytics across heterogeneous health systems without requiring centralized pooling of sensitive records. Privacy-preserving AI could support a new collaborative analytics paradigm for patient access and healthcare operations. Such platforms should be evaluated through multi-institutional pilots that assess technical feasibility, governance readiness, privacy protection, and operational usefulness.
