Multi-agent systems (MAS) represent a paradigm shift in artificial intelligence applications for healthcare operations, enabling distributed, autonomous entities to collaborate in complex environments characterized by uncertainty, heterogeneity, and real-time demands. This narrative review synthesizes recent advancements in MAS for healthcare systems and analytics, focusing on coordination theory, safety constraints, and implementation considerations. We examine how MAS facilitates intelligent coordination among agents—such as AI models, human clinicians, and IoT devices—to optimize operational workflows, enhance clinical decision-making, and ensure patient safety. Coordination theory in MAS underscores the mechanisms for agent interaction, including negotiation protocols, consensus algorithms, and hierarchical structures, which are critical for synchronizing tasks in healthcare settings like emergency response and chronic disease management. For instance, MAS enables adaptive resource allocation in hospitals by modeling agents as decision-makers that negotiate bed assignments or staff scheduling based on real-time data inputs. Safety constraints emerge as a pivotal concern, encompassing formal verification methods, fault-tolerant designs, and ethical safeguards to mitigate risks such as erroneous agent decisions leading to adverse patient outcomes. Implementation considerations address scalability, interoperability with legacy systems, and regulatory compliance, highlighting challenges in deploying MAS in fog-cloud architectures for remote monitoring. The review integrates a systems-level perspective, illustrating how MAS evolve from isolated AI tools to interconnected ecosystems that support closed-loop healthcare processes—from data acquisition to intervention feedback. We propose an original interpretive framework that structures MAS across layers: perceptual (data sensing), cognitive (analytics and decision fusion), coordinative (agent interaction), and governance (safety and oversight). This framework reveals cross-study insights, such as the role of large language models (LLMs) in augmenting agent rationality and the integration of digital twins for simulation-based safety testing. Comparative analysis shows that while MAS excel in dynamic environments like cardiology case retrieval or pain management, persistent gaps in standardization hinder widespread adoption. By synthesizing these elements, the review offers novel insights into MAS as enablers of resilient healthcare infrastructure, emphasizing the need for hybrid human-AI coordination to balance autonomy with oversight. Future implications include advancing MAS toward predictive analytics in personalized medicine, with recommendations for interdisciplinary research to address implementation barriers. Ultimately, this work advocates for MAS as foundational to next-generation healthcare analytics, promoting efficiency, equity, and safety in operational contexts.

Healthcare operations are constrained by demand volatility, resource scarcity, staffing pressures, and interdependent patient pathways. Artificial intelligence and predictive analytics offer a way to anticipate operational stress before it becomes visible in queues, bed shortages, overtime, or delayed care. This systematic review examines predictive analytics models applied to hospital staffing, scheduling, bed capacity, patient flow, and service demand forecasting from 2017 to 2022. The objective is to synthesize model types, data sources, operational targets, validation approaches, and implementation maturity across these domains. A PRISMA 2020–compliant review design was used to guide database searching, screening, eligibility assessment, extraction, and synthesis. Searches covered PubMed, Scopus, IEEE Xplore, and Web of Science, with narrative synthesis grouped by operational domain and risk of bias considered using an operationally adapted PROBAST-AI lens. The evidence base was dominated by retrospective, single-centre studies demonstrating the technical feasibility of predictive analytics for bed demand, emergency department arrivals, admission prediction, discharge prediction, and length-of-stay estimation. Staffing and scheduling studies were less frequent, and prospective implementation in real operational workflows remained uncommon. Predictive analytics for healthcare operations management is technically mature but practically under-deployed. The central challenge is translating forecasts into staffing, scheduling, bed-management, and command-centre decisions that measurably improve operational performance.

Hospitals seek to compare performance on operational metrics and quality indicators, but sharing granular patient-level, unit-level, or institution-level data raises privacy, legal, reputational, and competitive concerns. Privacy-preserving analytics has therefore become increasingly relevant for health systems that need collective insight without centralized pooling of sensitive data. This systematic review examines privacy-preserving models used for operational benchmarking, quality monitoring, resource planning, and multi-institutional performance comparison in healthcare. The review focuses on federated analytics, federated learning, secure multi-party computation, differential privacy, homomorphic encryption, and secure aggregation. A PRISMA 2020-compliant search was designed for PubMed, Scopus, IEEE Xplore, and Web of Science covering studies published from 2017 to 2025. Records were screened by two reviewers, and eligible studies were synthesized narratively by application domain, privacy-preserving method, implementation maturity, and operational relevance. Federated learning and secure aggregation dominated the literature, with more recent work increasingly combining federated workflows with differential privacy, homomorphic encryption, or governance frameworks. Most studies addressed clinical prediction or biomedical analytics, while fewer directly examined operational benchmarking, capacity planning, or routine multi-hospital performance comparison. The technical foundations for privacy-preserving federated analytics are increasingly mature, but their translation into routine healthcare operations remains early. Evidence is strongest for multi-site clinical modeling and weakest for sustained operational benchmarking, resource planning, and governance-tested deployment.

Accurate prediction of demand for emergency, imaging, pharmacy, laboratory, and inpatient services is critical for hospital planning. However, forecasting models are typically built separately by department or institution, which limits their ability to learn from shared demand patterns. Hospitals generate rich operational demand streams, but patient-level data cannot usually be pooled across organizations. This creates a need for collaborative forecasting methods that preserve institutional control over sensitive operational records. This article proposes a federated multi-task learning framework for predicting service demand across multiple hospital units. The framework trains a shared predictive model across hospitals while each institution contributes only protected model updates. The framework includes local data adapters, a shared temporal learning backbone, task-specific forecasting heads, a federated aggregation layer, differential privacy mechanisms, and site-specific personalization modules. Together, these components support collaborative forecasting without transferring patient-level operational data. The framework could improve demand prediction by learning common temporal patterns across hospitals and service lines. It would also support local adaptation, reduce duplicated model development, and preserve data confidentiality. A privacy-preserving, collaborative approach to hospital demand forecasting could become a core infrastructure for multi-site operational coordination. Federated multi-task learning offers a practical conceptual foundation for such a system.

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.

Hospitals generate dense streams of timestamped operational events, including orders, transfers, staff actions, queue changes, and system interactions. These events describe how care actually unfolds, yet much of their value remains unused because they are rarely labeled for prediction tasks. Existing operational predictive models often depend on task-specific labels, handcrafted features, and local workflow assumptions. This limits their ability to scale across hospitals, departments, and evolving operational conditions. This manuscript designs a self-supervised representation learning model that pre-trains on diverse healthcare operations event streams. The goal is to learn a generalizable embedding of hospital operational state that can be adapted to multiple downstream prediction tasks. The proposed model uses a transformer-based architecture trained with masked event modeling and temporal contrastive learning. Timestamped orders, transfers, staff actions, queue transitions, system interaction logs, and unit-level workflow signals are represented as time-aware event sequences, and the pre-trained backbone is later fine-tuned for specific operational tasks. Conceptually, the model could learn semantic and temporal regularities of hospital workflow, such as common discharge sequences, clustered STAT order activity, and operational precursors to bottlenecks. These representations would be expected to support downstream tasks such as delay forecasting, anomaly detection, and resource demand estimation when labeled data are limited. Self-supervised learning could unlock the latent value of healthcare operations logs by creating reusable representations of hospital workflow. Such a model could become a foundation for operational analytics, enabling faster and more adaptable development of predictive tools.

Agentic artificial intelligence systems—those capable of planning, executing, adapting, and learning across operational tasks—are beginning to influence healthcare administrative workflows. Their emergence raises important questions about autonomy, safety, oversight, and accountability in hospital systems. This systematic review examined the development and deployment of agentic AI in healthcare operations from 2017 to 2026. The review focused on autonomous discharge coordination, task routing, human oversight, safety guardrails, and workflow accountability. A PRISMA 2020–aligned search was conducted across PubMed, Scopus, IEEE Xplore, and Web of Science. Studies were screened by two reviewers, and eligible records were synthesised narratively according to task type, agent capability, oversight model, safety mechanism, and deployment maturity. The evidence base was nascent, heterogeneous, and dominated by predictive, prototype, implementation, and early deployment studies. Most systems supported discharge planning, workflow prediction, task prioritisation, or operational decision support rather than fully autonomous execution. Agentic AI has substantial potential to improve hospital operations, especially in discharge coordination and workflow routing. However, real-world deployment requires stronger safety engineering, prospective evaluation, explicit human oversight, and auditable accountability structures.

Foundation models pre-trained on massive, multimodal data have transformed several areas of artificial intelligence. Their adaptation to healthcare operations analytics is an emerging frontier because hospital workflows generate dense streams of structured, textual, temporal, and administrative data. This systematic review examined applications of foundation models to patient flow prediction, documentation burden estimation, resource allocation, and operational risk forecasting from 2017 to 2026. The review focused on multimodal pretraining, transfer learning, downstream adaptation, validation, and implementation maturity. A PRISMA 2020-compliant search was designed for PubMed, Scopus, IEEE Xplore, and Web of Science. Records were screened by two reviewers, and eligible studies were synthesized narratively by operational domain, model architecture, data modality, and maturity level. A small but rapidly growing body of work suggests that pre-trained multimodal models may support operational prediction tasks across healthcare systems. Evidence was concentrated in patient flow and resource allocation, while documentation burden estimation and operational risk forecasting were less frequently studied. Foundation models show potential to unify operational analytics across hospital systems. The field remains immature, with limited external validation, few prospective implementation studies, and no widely adopted benchmarks for operational foundation models.
