1 Introduction
Medical care involves the utilization of pertinent clinical data in conjunction with physicians to deliver effective treatments (1). Globally, healthcare systems face challenges such as an aging population, the prevalence of chronic diseases, shortages of healthcare personnel, rising medical costs, and increasing patient expectations. According to United Nations data, population aging is a distinct global trend of our times, In 2021, there were 761 million people aged 65 and over globally, and this figure is projected to rise to 1.6 billion by 2050. The population aged 80 and above is growing even more rapidly. Regarding cardiovascular diseases, in 2016, 8.4 million people died from cardiovascular diseases in South Africa (one of the BRICS nations). Between 1992 and 2016, the age-standardized mortality rate for cardiovascular diseases in the BRICS countries declined by −17%, which was less than the decline seen in North America (−39%) (2). For chronic respiratory diseases, between 1990 and 2017, the incidence of CRD, COPD, pneumoconiosis, and asthma declined, whereas the incidence of interstitial lung disease and sarcoidosis showed an upward trend. Elderly individuals are particularly susceptible to CRD, except for asthma. The acceleration of population aging and increased exposure to risk factors such as particulate matter pollution will contribute to the growing burden of chronic respiratory diseases globally (3). The International Labour Organization (ILO) estimates that by 2030, there will be a global shortage of 18 million healthcare workers (4). To address these issues, the United States enacted legislation in 2009 to promote the comprehensive development of healthcare informatics (5), and China’s 14th Five-Year Plan emphasizes the role of information technology in driving high-quality healthcare (6). The COVID-19 pandemic has further highlighted the importance of quality healthcare (7), while the rapid development of 5G technology has increased the demand for high-quality care, accelerating the progress toward smart healthcare.
The Internet of Things (IoT) offers the potential for intelligent care through the collection of information via sensors and the transmission of this data for the intelligent monitoring and tracking of patients. IoT’s terminal sensing layer, including smart bracelets, remote monitoring devices, and wearable sensors, enables healthcare professionals to obtain real-time health data from patients.
This data includes vital signs such as heart rate, blood pressure, glucose levels, and sleep patterns, which can help in early detection and timely intervention for health issues. Umer et al. (8) utilized IoT to construct an ET-CNN model for remote monitoring of heart rate in cardiac patients with an accuracy of 0.9524. Alshammari (9) employed an IoT-based MQTT model for accurate detection of patients’ vital signs and secure data transmission. Moreover, IoT technologies can be combined with artificial intelligence (AI) and big data analytics to provide personalized health recommendations and treatment plans tailored to each patient’s unique health needs. Astell et al. (10) provided personalized tablets for long-term care residents to enhance their quality of life. Ni Ki et al. (11) used a Latent Dirichlet Allocation model based on IoT to tailor treatment plans for diabetic patients, improving their outcomes. This approach not only enhances the precision and effectiveness of treatments but also empowers patients to better manage their own health, improving their overall quality of life.
The application of Internet of Things (IoT) technologies plays a crucial role in enhancing nursing efficiency and reducing costs. Traditional nursing models often require substantial human resources and time, particularly in geriatric care and chronic disease management. Through automation and intelligent means, IoT technologies can significantly alleviate the burden on healthcare providers and decrease medical expenses (12, 13). Partners HealthCare (14) provided home monitoring for over 3,000 patients with congestive heart failure, resulting in a 44% reduction in hospital readmissions over six years and saving more than $10 million. Mullins et al. (15) found that through the application of IoT in healthcare, consultation times were reduced by over two minutes, and patient out-of-pocket costs decreased by $1,229 to $2,700. Smart pillboxes can remind patients to take their medications on time, ensuring continuity and effectiveness of treatment and reducing complications from missed or incorrect doses (16). Furthermore, El-Saleh et al. (17) noted that the global digital health market was valued at approximately $175 billion in 2019. These smart devices not only improve the efficiency of care but also reduce costs.
The integration of IoT technologies into healthcare has significantly enhanced the quality and safety of care, while also driving the digitization of nursing processes (18). In terms of process digitization, IoT devices have enabled many automated management functions (19, 20). This paper will analyze key IoT technologies, discuss the design framework for a smart IoT nursing platform, and explore future technological advancements.

In Western countries, blogs have been integrated into nursing education to enhance learning outcomes, while Eastern countries are still exploring the potential of this technology in nursing education (110). De Raeve et al. (111) found that out of 35 European countries surveyed, 11 have national legislation specifying minimum educational requirements for nurses, with most requiring a master’s degree for advanced practice nurses. Additionally, Estonia, Iceland, Malta, and Sweden mandate at least two years of practical experience (112). The use of mobile health systems, particularly in China, has facilitated the development of Java Web-based intelligent outpatient care service platforms to address evolving healthcare needs (67, 113). In some advanced regions of China, 5G networks and artificial intelligence robots have been deployed in smart nursing platforms, enhancing personalized medical services and accelerating digital transformation in healthcare (114). In the United States, emphasis is placed on integrating smart nursing platforms into home care delivery processes to improve care quality and reduce costs, as evidenced by studies on the integration of Smart Care Platforms (SCPs) into home care provision (115, 116). Perspectives from Italy, Brazil, and the Philippines highlight the integration of clinical nursing information systems with electronic health records and the challenges and advancements in nursing informatics across different healthcare systems (117).
The implementation of Internet of Things (IoT) technologies in healthcare settings in low- and middle-income countries (LMICs) has been a topic of interest in recent literature. (118) conducted a multi-country case study focusing on the adoption and implementation of a network of university hubs for social innovation in healthcare delivery across Africa, Asia, and Latin America. The study aimed to describe the model, components, and implementation process of these hubs, identifying enablers and barriers that could be relevant to other LMIC universities interested in social innovation. In the context of the COVID-19 pandemic, (119) highlighted the importance of early implementation of effective measures by governments in controlling the spread of the virus, particularly in LMICs. The study emphasized that despite wealthier countries having elevated healthcare capacity, early and incremental government actions are crucial in LMICs to prevent the rapid spread of the virus. (120) focused on the safe handling of chemotherapy drugs in LMIC healthcare facilities, conducting a survey among 53 facilities in different income categories. The study provided an overview of practices in dealing with chemotherapy drugs, shedding light on the challenges faced by healthcare facilities in LMICs. Furthermore, (121) examined national hospital accreditation programs in the Eastern Mediterranean Region, including case studies from Egypt, Jordan, and Lebanon. The study addressed design and implementation issues of these programs, offering insights into the healthcare quality improvement initiatives in LMICs. In a study by Dkhimi et al. (122), the authors synthesized findings from six country case studies examining multiple funding flows to public healthcare providers in LMICs. The qualitative findings revealed the potential impact of multiple payment streams on healthcare provider behavior, highlighting the complexities of funding mechanisms in LMIC healthcare systems. Overall, the literature review indicates a growing interest in exploring the implementation of healthcare initiatives, such as social innovation hubs, COVID-19 control measures, chemotherapy drug handling practices, hospital accreditation programs, and funding flows in LMICs. These studies provide valuable insights into the challenges and opportunities for implementing healthcare interventions in resource-constrained settings.
4.2 Specific effects of IoT on enhancing nursing levels globally
Abdulrazak et al. (123) utilized environmental sensors, enhanced device monitoring, and change-point detection algorithms to study urinary function in 16 French patients, focusing on urinary tract infections and irritable bowel syndrome. The algorithm analyzed daily bathroom frequency and activity changes, enabling healthcare providers to track health status through alerts, thereby improving diagnostic and therapeutic outcomes. Yesmin et al. (124) demonstrated that IoT interventions in healthcare improved hand hygiene compliance rates and staff experiences, with a direct reduction in patient falls leading to improved nursing times. Abril-Jiménez et al. (125) found that digital home hospitalization services based on IoT enhanced patient autonomy, reduced hospital stays (from an average of 11 to 6 days), implemented four disease-specific protocols with up to 16 different pathways, lowered readmission rates, achieved 95% patient satisfaction, and increased professional trust and workload management. Mudawi (126) proposed an IoT-based intelligent ICU patient monitoring system capable of real-time measurement of patient parameters, greatly assisting doctors and hospitals in continuous patient monitoring and rapid decision-making. Yongjoh et al. (127) implemented the NU Medical system using blockchain technology in a Thai hospital with 157 healthcare workers, achieving rapid and confidential access to medical conditions, enhancing staff efficiency and patient satisfaction.
4.3 Case analysis of IoT enhancing nursing levels in China
Ni et al. (128) used telemedicine technology to promote a renal anemia management system (the Red China project aimed to develop a dialysis registration system based on the WeChat mobile platform) which resulted in a decrease in the proportion of patients with hemoglobin levels < 8 g/dL from 4.96 to 4.08%. Wang and Liu (129) designed the RASAP-POCT system utilizing IoT to support real-time data collection, on-site screening, and integration with contact tracing systems, providing saliva sample test results within 20–30 min with lower reagent complexity (approximately 50% less per reaction) and cost, while maintaining higher reliability, thus improving public health surveillance and intervention and enhancing SARS-CoV-2 testing in China. Shen et al. (130) described China’s “no second visit” program, which leverages internet-based care delivery methods to enhance outpatient services, reducing waiting times (appointment waiting time shortened by 4.05 min; consultation time shortened by 0.37 min; payment waiting time reduced by 3.09 min), increasing efficiency, and improving patient satisfaction. Qin et al. (131) developed an IoT cloud computing platform with an IN model, where wireless temperature monitoring systems (WTMS) and vital sign monitoring systems (VSMS) play a crucial role. Real-time monitoring of patients through radiofrequency identification of sensors attached under the armpit significantly improved the efficacy of HGG treatment for pediatric pneumonia sepsis and reduced adverse reactions. Hu et al. (132) found that implementing a tertiary enteral nutrition care system under the “internet + healthcare” model has been shown to improve nurses’ cognition, behavior, and core competencies in enteral nutrition safety care (P < 0.05), leading to positive clinical outcomes.
4.4 Technological efficacy and challenges
The application of the Internet of Things (IoT) in healthcare has expanded considerably, bringing about significant technological benefits and challenges. Through real-time monitoring and data collection from sensors and devices, IoT enables continuous monitoring of patients’ physiological indicators, enhancing the precision of diagnostics and treatments. Additionally, the proliferation of remote healthcare and nursing services provides convenience for patients in remote areas and those with mobility issues, markedly improving healthcare efficiency.
However, the quality and reliability of data pose significant challenges to nursing decisions. The accuracy and completeness of data directly impact the reliability of medical decisions (133). Bernardi et al. (134) argue that well-established and validated workflows for healthcare data quality assurance are beneficial for ensuring data quality. Poor dimensions and outcomes of data quality can be evaluated through various classification methods (135). Elucidating the intricate relationships among DQ dimensions and their impacts on clinical, clinician, research, business process, and organizational outcomes. It identified six core dimensions of DQ—accessibility, accuracy, completeness, consistency, contextual validity, and currency—that collectively form the foundation of data quality. Notably, consistency was recognized as a pivotal factor influencing all other dimensions, while both consistency and accessibility exert significant influence on all DQ outcomes. To address these DQ issues, we propose a set of solutions: Firstly, there is a need to enhance the management of data consistency to ensure uniformity across different data sources, thereby mitigating errors arising from inconsistencies. Secondly, optimizing data accessibility is essential, ensuring authorized users can efficiently obtain necessary information, which in turn enhances the effectiveness of clinical decision-making. Lastly, it is imperative to establish a continuous DQ monitoring mechanism to periodically evaluate the status of each DQ dimension and adjust data governance strategies accordingly to maintain high standards of data quality. This framework provides healthcare institutions with a systematic approach to addressing DQ issues, aiding in the optimization of resource allocation and the enhancement of service quality and efficiency.
Data interoperability is a significant challenge in modern digital environments, involving the ability to share and exchange data among multiple systems or platforms. However, in practice, data interoperability faces numerous issues such as incompatible data formats, insufficient data standardization, data security concerns, and lack of common data interfaces and protocols. These problems not only limit the value and utilization efficiency of data but may also have negative impacts on business decision-making and strategic planning.
To address these data interoperability issues, a series of effective measures should be taken. First, unified data standards and norms should be established to ensure consistency and interpretability of data. Second, data security and privacy protection measures should be strengthened by developing corresponding policies and regulations to guarantee the safety and legal use of data. Additionally, common data interfaces and protocols can be developed so that different systems or platforms can communicate and interact with each other. Simultaneously, promoting open-source technologies and tools can enhance data openness and sharing, improving data utilization and value. Finally, establishing cross-domain and cross-industry cooperation mechanisms can facilitate data resource integration and sharing, driving innovation and development of data (136).
With the advent of the digital era, issues related to data security and privacy breaches have become increasingly severe. Unauthorized access, modification or destruction of data can lead to loss, leakage or malicious use of data, which not only poses a threat to individual privacy but also may have serious implications for business operations and national security. To address these problems, it is necessary to establish sound management systems and technical safeguards, enhance employee awareness training, introduce legal and policy regulation, promote privacy protection technologies and products, and raise public awareness and self-protection capabilities. Only by continuously strengthening management and technological innovation can effective protection of data security and personal privacy be achieved (136).
User acceptance and adherence represent another critical challenge, especially for elderly individuals and those unfamiliar with technology. Resistance to and difficulties in using IoT devices affect their adoption and effectiveness (137). Personalized and intelligent nursing services provided by IoT can increase acceptance among older adults (138). Furthermore, healthcare professionals can improve their acceptance of IoT-based smart healthcare through cognitive and emotional pathways (139).
However, there is also a need to address ethical dilemmas associated with the implementation of IoT technologies in healthcare settings. One such dilemma is the potential deskilling of medical practitioners due to reliance on automated systems. While these systems aim to enhance diagnostic accuracy and patient monitoring, they could inadvertently reduce the clinical skills of healthcare workers if over-reliance occurs (140). Another ethical issue pertains to data ownership and privacy concerns. With vast amounts of sensitive health data being collected, ensuring secure storage and transparent data sharing practices becomes paramount (141).
To mitigate these challenges, robust training programs and regulatory frameworks are essential. Training initiatives should focus not only on technical proficiency but also on ethical considerations, helping both patients and healthcare providers understand the benefits and limitations of IoT applications (142, 143). Regulatory bodies must establish guidelines that protect patient data while promoting innovation and interoperability within the healthcare sector.
Moreover, the high initial investment and ongoing maintenance and update costs of IoT devices pose significant challenges to economic feasibility and sustained development (141). While the initial investment in IoT devices may be high, integrating these technologies into smart city initiatives can facilitate transitions toward greater sustainability (142, 143). Leveraging IoT and digital economy opportunities can promote national development, particularly during crises such as the COVID-19 pandemic, demonstrating the potential for economic growth and resilience through smart education, smart cities, smart homes, and e-health services (140).
Short-term gains include reduced equipment downtime through predictive maintenance, optimized inventory management that minimizes waste, and enhanced staff efficiency via real-time tracking systems. For instance, the University of Washington Medical Center saw a reduction in equipment failure rates and maintenance costs after implementing IoT-based predictive maintenance programs.
Long-term financial implications are even more profound. IoT facilitates preventive care and chronic disease management, potentially decreasing hospital readmissions and treatment costs. Additionally, IoT opens up new revenue streams through telemedicine and personalized health plans. Teladoc Health, for example, expanded its telehealth offerings using IoT technology, boosting profitability.
Case studies illustrate these benefits clearly. The Royal Adelaide Hospital’s use of IoT for asset tracking and environmental monitoring led to better asset utilization and patient safety. Philips Healthcare’s partnership with hospitals to deploy IoT-enabled patient monitoring systems demonstrated the ability to detect issues proactively, reducing complications and associated costs.
The integration of IoT technologies in nursing practice can significantly mitigate the impact of workforce shortages. By leveraging smart devices and sensors, IoT enables remote patient monitoring, which reduces the need for constant on-site staffing and allows healthcare professionals to manage a larger number of patients efficiently. For instance, smart wearables that monitor vital signs can transmit real-time data to nursing stations, enabling staff to prioritize care and intervene promptly when necessary (144). Additionally, the use of telehealth platforms facilitated by IoT can extend the reach of healthcare providers, offering virtual consultations and reducing the physical demands on the nursing workforce (26).
IoT has the potential to revolutionize patient monitoring in rural areas, where access to healthcare services is often limited. By deploying IoT-enabled sensors and devices, remote health monitoring becomes feasible, allowing patients in rural settings to receive continuous care without the need for frequent travel to urban medical centers. This is particularly beneficial for patients with chronic conditions who require regular health check-ups and medication management (145). Furthermore, IoT can facilitate the collection of health data from dispersed locations, providing healthcare providers with a comprehensive view of community health trends and enabling more informed care decisions (113).
Thus, while initial IoT investments may be high, the long-term financial viability and operational improvements make IoT solutions indispensable for modern healthcare providers seeking sustainable growth and enhanced patient care.
