1. Introduction
Interoperable multilayer networks are pivotal in transforming public health by enhancing disease control strategies and diagnostic systems (Loza et al., 2012). By employing computational algorithms to replicate realistic social models of educational institutions, these multilayer networks assist in identifying vulnerable populations and optimizing control measure distribution during disease outbreaks. Moreover, diagnostic systems based on neural networks contribute significantly to detecting health risks such as hypertension, achieving a high level of effectiveness.
These networks enable the integration of varied health intelligence data, enhancing disease detection, alerting, response, and prediction capabilities during public health crises. Additionally, implementing data sharing standards and interoperability, coupled with innovative methodological approaches, workforce structures, and data governance, guarantees the security and reliability of public health data systems.
Within this framework, digital health concerns use digital technologies for health. This process involves incorporating different technological tools into healthcare, such as eHealth (Hallberg & Salimi, 2020), mobile health (mHealth), telemedicine (Groom et al., 2021), and utilizing computer science concepts like big data and artificial intelligence (Hyder & Razzak, 2020).
This study shows the link between digital health, which is increasingly used in public healthcare, and multilayer networks. These networks consist of advanced structures where multiple layers interact through connecting copula nodes (represented by IT devices, m-Apps, EHRs, etc.).
The multilayer network architecture, characterized by its intricate system of interconnected layers, each serving a specific function, offers a high degree of adaptability, expansiveness, robust security measures, and unwavering dependability essential for accommodating the intricate and demanding specifications inherent in digital health. By enabling efficient data management and communication between various healthcare stakeholders, multilayer networks play a crucial role in expanding access to healthcare services, improving patient outcomes, and making healthcare systems more resilient and cost-effective. This multilayer design structure is vital in digital health for diverse services support: Digital health requires transmitting various data types, including voice, video, and significant medical files. Multilayer networks can efficiently handle this diversity by segregating services based on bandwidth and latency requirements and coordinating devices (smartphones, tablets, etc.).
Scalability—the ability of an information system to maintain its equilibrium State with increased storage volume—is another core issue that adds flexibility to healthcare ecosystems (Satamraju, 2020) that can face severe and unforeseen stress (as in the case of pandemics). The demand for digital health services can fluctuate significantly, driven by factors such as pandemics or changes in healthcare policies. Multilayer networks can scale up or down based on demand, ensuring that the network infrastructure can always meet the needs of healthcare providers and patients.
Preserving patient data privacy and security holds utmost importance within the healthcare sector. Multilayer networks can implement advanced security protocols and encryption at various levels (Fareed & Yassin, 2023), offering robust protection against unauthorized access and data breaches. This protection is especially important for sensitive medical data transmitted during digital health consultations.
Healthcare services need reliable networks to guarantee uninterrupted digital health consultations and data transfers. Multilayer networks can provide backup solutions, allowing seamless service even if one path or layer experiences issues.
Multilayer networks also prioritize Quality of Service management, which is crucial for digital health services. This process ensures that high-priority services such as live video consultations always have capacity and speed, even during network congestion.
Consistent with this introductory framework, the paper is structured as follows: digital health and its public health implications will be briefly introduced before a fundamental multilayer network analysis. The two topics will then be jointly examined, analyzing their public implications, even in cost/benefit analysis and scalable digital health ecosystems. A brief discussion anticipates the conclusion.

The link between digital health and multilayer networks involves how digital health relies on advanced and interconnected network infrastructures to deliver healthcare services remotely.
Network Science (Barabási, 2016) is a prolific field coming from several disciplines, which is compatible with the increasing use of Big Data (Bianconi, 2018), even in healthcare (Palanisamy & Thirunavukarasu, 2019). In the beginning, single networks can be classified as undirected or directed.
Multilayer networks are complex and advanced systems distinguished by many interconnected networks, where each stratum represents a unique classification of interaction, association, or linkage. This system starkly contrasts conventional network models, which typically concentrate on singular connections between nodes; in contrast, multilayer networks encompass multiple strata, with each layer symbolizing a unique form of relationship or interaction between entities. This approach provides a more nuanced and comprehensive understanding of complex systems by examining the intricate interrelations among various layers.
Multilayer networks present a formidable instrument for encapsulating the intricacy of real-world systems, offering perspectives that may not be readily discernible when employing more basic, single-layer network frameworks.
Multilayer networks, also known as multiplex networks according to Bianconi (2018), are intricate mathematical constructs utilized by researchers and professionals to gain insights into, make predictions about, and exert control over the complicated dynamics of complex systems spanning a diverse array of fields, such as the realm of public healthcare.
The mathematical formulation of multilayer networks involves a meticulous examination of the inter-layer connections between nodes across different layers, contributing to the model’s overall complexity and richness.
To define copula nodes that connect different layers, we introduce additional nodes, called copula nodes, which serve as bridges between layers. A copula node can be connected to nodes in different layers, facilitating the interaction or information flow between them. The connectivity pattern of copula nodes is typically defined based on the specific application and desired network structure.
One way to represent inter-layer connections in a multilayer network is through inter-layer coupling matrices C, where ′Cll′ denotes the strength of the connection between layer l and layer ′l′. These coupling matrices can model how information or influence propagates across layers. Multilayer networks are dynamic, showing a temporal evolution (incorporating machine learning) and allowing for a combination of synergistic networks linked by connecting copula (replica) nodes.
Multilayer networks’ complexity and ability to represent multiple types of interactions, relationships, and connectivity make them particularly suited for digital health applications. They offer a flexible, scalable, resilient framework for integrating diverse data sources and facilitating comprehensive, patient-centered healthcare delivery.
In healthcare and digital health, these layers can represent various data and communication channels, such as EHRs, telehealth video conferencing systems, wearable health devices, and more.
Critical characteristics of multilayer networks impacting digital health are reported in
Table 1.
Some typical applications of multilayer networks in digital health (Balram et al., 2016) include Patient Interaction Networks between patients based on relationships such as social interactions, co-occurrence in healthcare facilities, or shared medical conditions.
Other applications refer to understanding the disease spread (through transportation networks, social interactions, and genetic similarities) across different populations or geographical regions. Networks catalyze the integration of heterogeneous data sources such as genomics, EHRs, and lifestyle information to develop personalized treatment strategies and predict patient outcomes, optimizing the allocation of healthcare resources such as hospital beds, medical personnel, and medical supplies by modeling the interconnectedness of healthcare facilities and patient flows.
