Introduction and background
Swarm intelligence, inspired by the collective behavior of social insects like ants, bees, and termites demonstrates vast potential for solving complex problems in artificial intelligence. Its decentralized, self-organized nature and ability to adapt renders it particularly effective for dynamic, intricate issues across many domains including healthcare. The application of swarm intelligence within healthcare has gained significant momentum attributable to ever-increasing medical data complexity, imperative demand for efficient diagnostics and therapies, and personalized care requirements.
Swarm intelligence algorithms have proven remarkably useful for disease diagnosis and treatment optimization facilitating mining and analysis of substantial healthcare information to meaningfully improve major disease prognoses such as cancer, heart conditions, and tumors. For example, as highlighted by Nayar et al., swarm intelligence plays an indispensable role in diagnosis and therapies through integrated data mining techniques [1]. Moreover, Rosenberg et al. illustrated that small groups of networked radiologists functioning as a living swarm intelligence system decreased diagnostic errors by 33% while outperforming state-of-the-art deep learning when evaluating pneumonia from chest X-rays [2]. Particle swarm optimization (PSO) techniques and ant colony optimization have also demonstrated efficacy in medical imaging evaluation and disease monitoring serving to enhance diagnostic processes and outbreak surveillance. Simran and Singh offer a thorough review of particle swarm optimization - ant colony optimization (PSO-ACO) optimization and swarm intelligence applications within medical imaging and disease tracking emphasizing their potential to transform healthcare [3].
Swarm intelligence frameworks, like the Internet of Medical Things (IoMT), enable real-time continuous and remote patient monitoring while supporting essential decision-making processes in healthcare. These frameworks are particularly valuable for smart healthcare environments, delivering ceaseless tracking of patients, especially seniors, to boost care provision and outcomes. El-Shafeiy and Abohany debate the strength of a swarm intelligence system in IoMT for intelligent healthcare infrastructure [4]. In addition, swarm learning combines edge computation and blockchain to safeguard data privacy while improving the precision of medical classifiers. This hybrid approach facilitates the joining of decentralized data pools, enhancing analysis and remedy paths. Warnat-Herresthal et al. demonstrate the practicability of employing swarm learning for evolving disease classifiers, displaying its potential to quicken customized medication [5]. Hybrid swarm cleverness algorithms have since been advanced to boost the performance of care services, particularly in streamlining task scheduling and asset distribution in cloud computing platforms. Hassan et al. propose a mixed optimization algorithm that merges PSO and the salp swarm algorithm (SSA), exhibiting its superiority over present algorithms regarding makespan, waiting time, and resource use [6].
Recent advancements in swarm intelligence have also shown promise in optimizing drug delivery systems, bioinformatics, and personalized medicine. For instance, hybrid swarm intelligence algorithms have been employed to optimize nanoparticle delivery systems, enhancing the precision and efficacy of targeted drug delivery [7]. In bioinformatics, swarm algorithms such as artificial bee colony (ABC) have been utilized for protein structure prediction, improving the accuracy and speed of computational biology processes [8]. Additionally, swarm intelligence has been integrated with machine learning to develop predictive models for personalized medicine, which tailor treatments based on individual genetic profiles [9]. Swarm-based optimization has also been applied to enhance the performance of wearable medical devices, ensuring better monitoring and management of chronic diseases [10]. Furthermore, swarm intelligence is being used to design more efficient and adaptive healthcare logistics systems, which streamline the supply chain and improve the delivery of medical supplies [11].
In a recent study, Bijli et al. underscored the very dynamic domain of swarm nanorobotics, boasting its disruptive technologies to come for health applications, from oncology and drug delivery to surgery. Though much hope is placed on the promising abilities it does carry, there are challenges of formidable dimensions in regard to swarm control, navigation, and obstacle avoidance if nanorobots are supposed to envelop seamless integration into medical practice [12]. Kioskli et al. proposed a novel framework inspired by swarm intelligence for improving cybersecurity in healthcare ICT, which imitates biological swarm behavior to improve threat detection, analysis, and response. This approach brings together such advanced technologies as artificial intelligence, security engineering, and privacy engineering to create a highly interconnected system supporting dynamic intelligence, scalability, and fault tolerance within healthcare infrastructures, hence strengthening the resilience of digital healthcare systems and supply chains against attacks [13].
Bibliometric analysis provides quantitative insights into scientific publications through computer tools, assessing core authors and key findings while revealing interconnected relationships [14]. This statistical approach offers perspectives on productivity and influence by evaluating journal impact factors by analyzing interlinks between works [15,16]. Data sourced from databases like Web of Science, Scopus, or Google Scholar undergoes cleaning to remove duplicates prior to an in-depth examination. Citation and collaboration techniques discern research clusters and networking, rendering bibliometric methods exceptionally beneficial for researchers, administrators, and librarians by facilitating efficient navigation amid vast scientific literature [17,18].
RStudio provides a robust platform for developing in R, offering desktop and web-based interfaces alike [19]. Bibliometrix, an open-source R package, facilitates visual exploration of scholarly literature through the import of references from databases, metric calculation, and representation of datasets for diverse investigations [20,21]. VOSviewer is analytical software permitting visualization and analysis of bibliographic networks, generating and portraying co-author, co-citation, and keyword co-occurrence mappings. With intuitive design and customizable graphics, VOSviewer aids in uncovering hidden patterns within publication repositories, revealing complex relationships and evolving trends [22,23]. Its strong functionality combined with usability earns it widespread application across disciplinary bibliometric inquiries.
This study aims to visualize research trends and collaborative networks within the emerging field of swarm intelligence applied to healthcare. The review maps the evolution of swarm-based methodologies that were employed in different medical scenarios through the systematic analysis of scientific publications from 2003 to 2024. It involves the identification of seminal works, key authors, and primary journals that make a significant impact in the domain, unearthing dominant topics, technologies, and areas of application. These would especially be algorithms of major importance, such as PSO and ACO, which help in the enhancement of diagnostic accuracy, optimization of treatment plans, and improvement of patient monitoring. This focused review of development and collaboration in this interdisciplinary field is streamlined by targeting these core methodologies and their direct applications to healthcare.
