Electronic health records (EHRs) are central to modern healthcare analytics but are often characterized by noise, ambiguity, and missing information, making reliable clinical phenotyping difficult. Clinical phenotypes—observable characteristics derived from patient data—are essential for diagnosis, prognosis, and treatment planning. Yet, traditional supervised machine learning methods depend on large volumes of high-quality annotated data that are difficult to obtain at scale.This review examines the role of weak supervision in enabling scalable clinical phenotyping from noisy and heterogeneous EHR data. Weak supervision frameworks generate labels using heuristic rules, knowledge-based signals, or programmatic labeling functions, allowing models to learn from large datasets without extensive expert annotation. These approaches help address challenges such as inconsistent terminology, missing values, and temporal irregularities commonly found in clinical records.We synthesize recent developments in scalable phenotyping systems that integrate machine learning architectures, probabilistic labeling strategies, and multimodal data representations to extract meaningful patterns from imperfect clinical data. The review also outlines a systems-level perspective on healthcare analytics pipelines, covering data ingestion, model training under label uncertainty, deployment in clinical environments, and governance considerations for responsible AI integration.Overall, weak supervision emerges as a practical strategy for transforming noisy EHR data into usable clinical intelligence, enabling more scalable and trustworthy analytics for healthcare decision support.

Ultimately, RAG holds promise for democratizing AI in healthcare, provided rigorous evaluation and safety protocols are embedded from design to implementation, paving the way for equitable, evidence-driven clinical intelligence.

The integration of generative artificial intelligence (AI) into clinical workflows represents a transformative shift in healthcare systems and analytics, promising enhanced efficiency in documentation tasks while introducing novel challenges in reliability and governance. This narrative review synthesizes recent literature on the utility of generative AI models, such as large language models (LLMs), in automating clinical documentation, including patient notes, discharge summaries, and diagnostic reports, which traditionally consume significant clinician time. Studies highlight how these tools can streamline data ingestion from electronic health records (EHRs), generating coherent narratives that align with clinical standards, thereby reducing administrative burdens and allowing more focus on patient care. For instance, generative AI has demonstrated proficiency in summarizing complex medical dialogues and classifying clinical notes, often outperforming traditional methods in speed and accuracy, as evidenced by evaluations in German healthcare settings and emergency departments. However, the utility is tempered by inherent failure modes, including hallucinations—where models produce factually incorrect information—and biases amplified from training data, which can propagate errors in clinical decision-making. Oversight mechanisms are critical to mitigate these risks, encompassing human-in-the-loop verification, regulatory frameworks like the EU AI Act, and ethical guidelines for deployment in high-stakes environments. From a systems-level perspective, generative AI enables closed-loop analytics in healthcare infrastructure, where data flows from ingestion to inference, informing interventions and feeding back for model recalibration. This review examines how LLMs facilitate intelligent clinical decision support, such as in patient care document verification using EHRs and prompt engineering for medical education. Yet, failures such as catastrophic errors in multimodal AI applications underscore the need for robust oversight, including transparency in model training and post-deployment monitoring.

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.

The integration of social determinants of health (SDoH) into artificial intelligence (AI) systems for healthcare represents a pivotal advancement in addressing inequities within clinical analytics and decision-making frameworks. SDoH encompass socioeconomic, environmental, and behavioral factors that profoundly influence health outcomes, yet their incorporation into AI models has been inconsistent, often exacerbating biases rather than mitigating them. This narrative review synthesizes recent literature on strategies for embedding SDoH data into AI pipelines, elucidates mechanisms of bias propagation, and evaluates approaches to equity assessment in healthcare systems. Drawing from peer-reviewed publications, we highlight the evolution of AI applications in healthcare analytics, where machine learning algorithms increasingly process electronic health records (EHRs), wearable data, and population-level datasets to predict risks and optimize interventions. However, without deliberate integration of SDoH, these systems risk perpetuating disparities, as evidenced by models that underperform for underrepresented groups due to skewed training data. Integration strategies range from data augmentation techniques, such as linking EHRs with geospatial SDoH indices, to hybrid modeling approaches that fuse clinical variables with socioeconomic proxies. For instance, federated learning frameworks enable cross-institutional data sharing while preserving privacy, facilitating broader SDoH representation. Bias mechanisms are multifaceted, including selection bias from non-diverse datasets, algorithmic amplification of historical inequities, and deployment biases in real-world settings where AI outputs influence resource allocation. Studies demonstrate how unaddressed confounders, like zip code-based proxies for race or income, can lead to discriminatory predictions in areas such as readmission risk or treatment recommendations. Equity evaluation methodologies emphasize fairness metrics, such as demographic parity and equalized odds, adapted for healthcare contexts. Prospective audits, involving diverse stakeholder input, are recommended to assess model performance across SDoH strata. Consensus emerges on the need for governance structures that incorporate ethical AI principles, including transparency in SDoH feature engineering and continuous monitoring for drift. Challenges persist in standardizing SDoH data collection, with calls for interoperable ontologies to enhance AI generalizability. This review proposes a systems-level framework for SDoH-aware AI, advocating for closed-loop systems that integrate feedback from equity audits into model retraining cycles. Ultimately, advancing SDoH integration in healthcare AI requires interdisciplinary collaboration between clinicians, data scientists, and policymakers to foster equitable systems. By prioritizing bias mitigation and equity-centric design, AI can transition from a tool that mirrors societal inequities to one that actively reduces them, promoting health justice in analytics-driven care. Future directions include scalable implementations in low-resource settings and regulatory frameworks to enforce SDoH considerations. This synthesis underscores the transformative potential of SDoH-informed AI while cautioning against unchecked deployment that could widen health gaps.

The integration of artificial intelligence into healthcare systems has transitioned from isolated diagnostic tools to comprehensive workflow automation platforms that fundamentally reshape clinical operations, decision cycles, and accountability frameworks. This narrative review synthesizes studies that examine how AI-driven task modeling, human–AI interaction dynamics, and evolving accountability structures collectively enable scalable, safe, and ethically grounded automation across healthcare analytics and delivery infrastructures. Rather than cataloging isolated applications, the analysis adopts an original systems-level lens that organizes the literature into four interdependent layers—data orchestration, model orchestration, deployment orchestration, and governance orchestration—revealing recurring patterns of closed-loop intelligence that link real-time data ingestion to automated intervention and continuous recalibration. Task modeling emerges as the foundational mechanism through which heterogeneous clinical workflows are decomposed into machine-executable primitives while preserving human oversight at critical decision nodes. Multiple integrative reviews demonstrate that well-designed task ontologies reduce cognitive burden on clinicians by 30%–50% in high-volume settings such as nursing documentation, pathology slide triage, and echocardiographic measurement, yet success critically depends on explicit representation of human factors, including workload, trust calibration, and exception-handling protocols. Human factors literature further highlights the bidirectional influence between automation and clinician performance. While AI scribes and large language model-assisted note generation improve throughput, they simultaneously introduce new forms of automation bias and alert fatigue that must be mitigated through adaptive interface design and real-time transparency mechanisms. Accountability structures constitute the least mature yet most decisive layer of AI-enabled healthcare automation. Governance models that embed continuous human–AI shared liability, audit trails for every automated decision, and dynamic recalibration triggers are shown to be essential for regulatory acceptance and clinical adoption. Studies of real-world deployments in pathology foundation models and closed-loop infection prevention systems illustrate that accountability is not an afterthought but an infrastructural requirement: without traceable lineage from raw data through model inference to clinical action and feedback, organizations cannot fulfill medico-legal or ethical obligations. This review contributes an original integrative framework—the clinical intelligence loop—that formalizes the end-to-end automation architecture as a continuous cycle of data ingestion, task-modeled inference, human-augmented decision fusion, intervention execution, outcome monitoring, and governance-driven recalibration. Cross-study synthesis reveals that systems achieving sustained performance do so by maintaining tight coupling across all five stages rather than optimizing any single component in isolation. The analysis underscores that workflow automation in healthcare AI succeeds only when task modeling is human-centered, human factors are explicitly engineered into the loop, and accountability is infrastructural rather than retrofitted. These insights provide both theoretical scaffolding and practical guidance for health-system leaders, regulators, and technology developers seeking to scale responsible AI automation beyond pilot projects.

The rapid expansion of unstructured narrative data within patient safety event (PSE) reporting systems presents both a valuable source of safety intelligence and a major analytical challenge for healthcare organizations.

At the same time, generalization techniques support reliable deployment across diverse populations and clinical contexts, advancing scalable and adaptive digital healthcare systems.

Hospital workflow analytics has become central to improving throughput, reducing operational cost, and strengthening patient experience. Artificial intelligence offers predictive capabilities for patient flow, staffing, resource use, and delay anticipation. This systematic review examined machine learning models applied to patient flow, staff scheduling, resource utilisation, and operational delay prediction in hospital settings. The review focused on model types, operational endpoints, data sources, validation methods, and implementation maturity. A PRISMA 2020-aligned search strategy was designed for PubMed, Scopus, IEEE Xplore, and Web of Science. Screening, extraction, risk-of-bias appraisal, and narrative synthesis were structured around hospital operations rather than clinical diagnosis. The literature was dominated by retrospective, single-centre studies focused on patient flow, especially length-of-stay, admission, discharge, and bed-use prediction. Staffing, resource utilisation, and operational delay prediction were less frequently studied, and prospective deployment remained uncommon. Machine learning for hospital operations is maturing technically but remains fragmented across isolated workflow domains. Integration across patient flow, staffing, resource utilisation, and delay management requires stronger prospective evaluation.

Hospital length-of-stay is a central operational metric for inpatient capacity planning, discharge coordination, and resource allocation. Accurate prediction remains difficult because patient trajectories are heterogeneous, nonlinear, and shaped by evolving clinical events during admission. Traditional statistical models often have limited flexibility for high-dimensional and sequential electronic health record data. Across the literature, there is no settled consensus regarding optimal model architecture, feature representation, validation design, or clinical implementation strategy. This systematic review synthesizes machine learning approaches for hospital length-of-stay prediction published from 2017 to 2022. It focuses on EHR feature types, model architectures, validation methods, interpretability strategies, and reported operational outcomes. A structured review of peer-reviewed literature was conducted using targeted search strings related to machine learning, deep learning, electronic health records, discharge prediction, and hospital length-of-stay. The review included studies across emergency, inpatient, surgical, pediatric, cardiovascular, and intensive care settings. The literature suggests that gradient boosting, random forest, ensemble learning, and recurrent neural networks are common approaches for LOS prediction. However, external validation remains uncommon, prediction horizons vary widely, and operational implementation outcomes are reported less consistently than model development results. Future research should prioritize external validation, prospective implementation studies, standardized outcome definitions, and transparent reporting of workflow barriers. Shared benchmarking datasets and multi-center validation consortia would strengthen comparability across LOS prediction studies.

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.

Machine learning is increasingly used in hospital operations, revenue cycle management, and quality monitoring. These administrative applications require transparency because their outputs can influence access, resource allocation, financial decisions, and accountability. This systematic review examined explainable machine learning methods applied to operational decision support, revenue cycle analytics, and quality monitoring in healthcare administration. The review focused on the type, depth, and use of transparency methods rather than predictive performance. A PRISMA 2020–compliant search strategy was applied to PubMed, Scopus, IEEE Xplore, and Web of Science for studies published between 2017 and 2022. Screening, extraction, and narrative synthesis focused on administrative domain, model type, explanation method, stakeholder use, and risk of bias. SHAP and LIME were the most frequently discussed post-hoc explanation approaches, while feature importance, partial dependence, rule-based models, and attention mechanisms appeared in smaller subsets of the literature. Operational decision support showed the strongest explainability uptake, whereas revenue cycle analytics and administrative quality monitoring remained less developed. Explainability in healthcare administration remains uneven and often superficial. The largest gap is not the availability of explanation tools, but the limited evidence that explanations improve managerial decisions, accountability, fairness, or auditability.

Clinical documentation is central to continuity of care, coding, billing, compliance, and quality measurement, yet it remains a major source of administrative burden for physicians. Artificial intelligence, especially natural language processing, has been proposed as a way to improve documentation quality, coding accuracy, billing support, and clinical workflow efficiency. This systematic review synthesised evidence from 2017 to 2023 on natural language processing methods applied to clinical documentation improvement. The review focused on automated clinical coding, note quality, billing support, computer-assisted physician documentation, and physician workflow efficiency. A PRISMA 2020-compliant search strategy was applied to PubMed, Scopus, IEEE Xplore, and Web of Science for publications from 1 January 2017 to 31 December 2023. Screening was performed in duplicate, and eligible studies were narratively synthesised by documentation domain, model type, deployment maturity, and evaluation approach. The evidence base expanded rapidly during the review period, especially in automated coding and clinical note generation. Several studies reported technically promising systems for ICD coding, documentation summarisation, and speech-derived notes, whereas billing outcomes and sustained workflow effects were less commonly evaluated. Natural language processing for clinical documentation improvement appears most mature for automated coding and note analysis. Evidence for billing support and physician workflow transformation remains less developed, particularly in prospective clinical environments.

Efficient hospital resource allocation is a persistent operational challenge because demand for beds, staff, equipment, diagnostics, and patient movement changes rapidly. Predictive analytics offers a way to anticipate demand and support more proactive operational decisions. This systematic review synthesised machine learning models applied to hospital resource allocation from 2017 to 2023. The review focused on bed management, staffing demand, equipment use, diagnostic capacity, and patient throughput. A PRISMA 2020-compliant review process was used, including structured searches of PubMed, Scopus, IEEE Xplore, and Web of Science. Screening, extraction, risk-of-bias assessment, and narrative synthesis were conducted to compare model targets, data sources, validation approaches, and implementation maturity. The evidence base was dominated by retrospective studies of patient throughput, emergency department admission prediction, bed demand, and length of stay. Staffing, equipment, and diagnostic capacity forecasting were less frequently represented, while integrated multi-resource command centre models remained uncommon. Machine learning for hospital resource allocation has become technically advanced, but operational translation remains uneven. Most models remained retrospective or locally validated, with limited evidence of prospective deployment, workflow integration, or measurable operational impact.

Revenue cycle inefficiencies, including claim denials, coding errors, delayed reimbursement, and prior authorization workload, impose substantial administrative and financial burdens on healthcare organizations. Machine learning has been proposed as a decision-support approach for improving prediction, automation, and workflow prioritization in these areas. This systematic review examined peer-reviewed and closely related scholarly literature from 2017 to 2023 on machine learning for healthcare revenue cycle analytics. The review focused on claim denial prediction, coding automation, payment delay forecasting, and prior authorization support. A PRISMA 2020-compliant review process was used, including structured database searching, dual screening, and domain-based narrative synthesis. Risk of bias was assessed using criteria adapted from PROBAST-AI, with attention to temporal validation, data leakage, and implementation relevance. The literature showed the greatest maturity in automated clinical coding and emerging but narrower evidence for claim denial prediction. Evidence for payment delay forecasting and prior authorization support was more limited, with few studies describing prospective implementation or measured operational impact. Machine learning shows promise for improving revenue cycle decision support, but most evidence remains retrospective and technically oriented. Deployment is constrained by data fragmentation, explainability requirements, workflow integration, and regulatory caution.

Smart hospitals increasingly combine artificial intelligence, real-time data streams, operational dashboards, and automated decision support to coordinate care delivery. These systems aim to improve hospital throughput, staff efficiency, resource use, and patient safety. This systematic review synthesised evidence on AI technologies used in smart hospital management from 2017 to 2023. The review focused on command centers, real-time workflow monitoring, operational dashboards, and automated decision support systems. A PRISMA 2020-compliant review process was used, including structured database searching, dual screening, and narrative synthesis. Extracted data covered study characteristics, AI methods, deployment maturity, data sources, integration patterns, and reported operational impact. The evidence base was concentrated on hospital command centers, predictive dashboards, and patient-flow analytics. Real-time workflow monitoring and automated decision support were less mature, and prospective evaluations of operational or clinical impact were uncommon. AI-enabled smart hospital management is technologically promising but remains unevenly implemented and weakly evaluated. Current evidence supports cautious adoption, local validation, and stronger evaluation designs before claims of sustained operational transformation are accepted.

Healthcare quality improvement increasingly relies on routinely collected data to identify preventable harm, missed care opportunities, adverse outcomes, and variation in performance. Artificial intelligence predictive models may support earlier detection of quality risks and enable more proactive monitoring than retrospective audits alone. This systematic review examined artificial intelligence predictive models for healthcare quality improvement from 2017 to 2024. The review focused on patient safety events, care gaps, adverse clinical outcomes, and performance monitoring systems. A PRISMA 2020-compliant search was conducted across PubMed, Scopus, Web of Science, and IEEE Xplore for peer-reviewed English-language studies published from 2017 through 2024. Dual screening, structured data extraction, risk-of-bias assessment, and narrative synthesis were used. The evidence base showed growing use of machine learning for pressure injuries, sepsis, readmission, mortality, ICU transfer, and continuous monitoring. However, most studies remained retrospective model-development or validation studies, while fewer described deployment within formal quality improvement workflows. Technical progress in predictive modelling for quality improvement is substantial, but evidence of sustained improvement in care processes, safety outcomes, or organisational performance remains limited. Stronger prospective evaluation and clearer integration with improvement methods are needed.

Hospital patient flow depends on timely transfer decisions, accurate discharge planning, and reliable post-discharge coordination. Delays in placement, premature discharge, missed follow-up, and unrecognized post-discharge risk can increase avoidable utilization and compromise continuity of care. This systematic review examined machine learning models for predicting placement delay, discharge readiness, follow-up completion, and post-discharge risk from 2017 to 2024. The objective was to synthesize model purposes, data sources, validation practices, implementation maturity, and practical relevance for care transitions. A PRISMA 2020-compliant systematic review was conducted using PubMed, Scopus, IEEE Xplore, and Web of Science. Dual screening, structured data extraction, and narrative synthesis were used because heterogeneity in model objectives, predictors, settings, and outcomes prevented meta-analysis. The evidence base was largest for post-discharge readmission risk and discharge readiness prediction, while placement delay and follow-up completion received less focused attention. Prospective validation, workflow integration, and outcome-based implementation studies were uncommon across all four domains. Machine learning offers promising tools to support proactive discharge planning and transitional care, but the evidence remains dominated by retrospective model development. Translation into routine practice requires prospective testing, interpretability, equity assessment, and integration into multidisciplinary workflows.

Artificial intelligence models are increasingly used to support healthcare decision-making, resource allocation, clinical triage, population health management, and quality improvement. Without explicit equity assessment, these tools may reproduce, obscure, or scale existing disparities across racial, ethnic, sex, gender, socioeconomic, and geographic groups. This systematic review examined artificial intelligence approaches for healthcare equity analytics from 2017 to 2024. The review focused on bias detection, fairness-aware prediction, disparity monitoring, and algorithmic accountability in health systems. A PRISMA 2020-compliant search was conducted across PubMed, Scopus, Web of Science, and IEEE Xplore for peer-reviewed English-language studies published between 2017 and 2024. Eligible records were screened by two reviewers, and findings were synthesised narratively by equity task, method type, clinical application, fairness metric, and implementation context. The evidence base showed increasing attention to bias detection and fairness-aware algorithm design, especially in clinical risk prediction, diagnostic imaging, and population health management. Disparity monitoring systems and accountability structures were less frequently evaluated in deployed health system environments and were commonly described as governance recommendations, audit frameworks, or pilot-stage approaches. The technical foundations for equitable artificial intelligence in healthcare are advancing, but translation into operational health system practice remains limited. The strongest evidence concerns bias measurement, whereas evidence that fairness interventions reduce real-world health disparities remains nascent.

Healthcare administration generates large volumes of textual data, including clinical notes, billing documentation, incident narratives, portal messages, and operational records. These data create administrative burden but also provide opportunities for natural language processing to support documentation, coding, communication, safety review, and workflow automation. This systematic review examined natural language processing models applied to healthcare administration from 2017 to 2024. The review focused on five domains: clinical documentation, coding support, incident reporting, patient communication, and workflow automation. A PRISMA 2020-compliant review was conducted using structured searches of PubMed, Scopus, IEEE Xplore, and Web of Science for studies published between 2017 and 2024. Eligible studies were screened by two reviewers, extracted using a structured template, and synthesized narratively by administrative domain, model type, evaluation approach, and implementation maturity. Transformer-based models were increasingly prominent across the reviewed literature, particularly in documentation support, automated coding, and clinical text classification. Clinical documentation and coding support had the strongest evidence base, while incident reporting, patient communication, and workflow automation remained less mature and less frequently evaluated in real-world settings. Natural language processing for healthcare administration is technically promising, but most applications remain at the retrospective or proof-of-concept stage. Prospective validation, workflow integration, governance, and human oversight are needed before widespread operational adoption.

Healthcare administration is document-intensive, communication-heavy, and increasingly dependent on digital systems that require timely synthesis of clinical and operational information. Generative artificial intelligence has been proposed as a potential means of reducing administrative workload across documentation, reporting, patient communication, governance, and workflow coordination. This systematic review examined applications of generative artificial intelligence across five healthcare administrative domains: documentation support, operational reporting, patient communication, governance dashboards, and workflow automation. The review aimed to characterize reported use cases, model types, evaluation approaches, implementation barriers, and evidence maturity from 2017 to 2025. A PRISMA 2020-compliant search strategy was applied to PubMed, Scopus, IEEE Xplore, and Web of Science for studies published between January 1, 2017, and December 31, 2025. Screening was conducted in duplicate, and eligible studies were synthesized narratively by administrative domain. Documentation support was the most mature domain, particularly for clinical summarization, discharge summaries, patient-message drafting, and document classification. Operational reporting and governance dashboards were emerging areas, while patient communication and workflow automation showed diverse prototypes but limited prospective validation. Common challenges included hallucination, privacy, bias, regulatory uncertainty, integration burden, and limited evidence of real-world administrative impact. Generative artificial intelligence appears technically capable of supporting multiple healthcare administrative tasks, but evidence remains uneven across domains. Real-world impact, safety, scalability, and governance require stronger evaluation before these systems can be relied upon for high-stakes administrative decision-making.

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.
