Background Research and Available Knowledge

Public Health

Public health is a multidisciplinary field focused on the prevention of disease, promotion of health and extension of life through collective societal efforts. It addresses the physical, psychological and social dimensions of health across communities and populations, from local to global scales. The COVID-19 pandemic underscored the importance of health surveillance, early warning systems and population-level interventions—areas where data science plays an increasingly central role [1–11].

Key disciplines contributing to public health include epidemiology, biostatistics, social sciences and health economics, with subfields such as environmental health and behavioural health addressing specific population needs [11–22]. Data science enhances the impact of public health through predictive modelling, real-time analytics and geographic information systems (GIS) for tracking disease outbreaks, optimising resource allocation and informing public policy.

Despite advancements, significant challenges persist, particularly in developing countries. Limited infrastructure, insufficient healthcare personnel and financial constraints often hinder the deployment of effective public health systems [23–33]. Maternal and child health outcomes remain closely tied to malnutrition and poverty, highlighting the need for data-driven, equity-focused interventions. Ethical issues also arise when balancing individual rights with collective welfare in public health decision-making.

Oncology

Oncology is the medical discipline focused on the prevention, diagnosis and treatment of cancer—one of the leading causes of death globally. It encompasses multiple subspecialties, including medical, surgical, radiation and clinical oncology [12–22]. Advances in imaging, targeted therapies and genomics have significantly reshaped the field, with data science now accelerating the transition toward personalised medicine. Machine learning and deep learning algorithms support early cancer detection through radiological image analysis and genomic profiling. Predictive models assist in risk assessment and treatment planning, while clinical decision support systems (CDSS) improve therapy selection and patient stratification. Ethical considerations remain central, particularly in clinical trial enrolment, communication of prognoses and end-of-life care decisions. Data science tools—when implemented responsibly—can help oncologists navigate these challenges and optimise patient outcomes.

Diabetes

Diabetes mellitus is a chronic metabolic disorder characterised by hyperglycaemia due to insufficient insulin production or cellular insulin resistance [18–28]. With an estimated global burden exceeding 537 million cases in 2021, diabetes—particularly Type 2—is a major public health concern, often coexisting with obesity and cardiovascular diseases. Data science plays a vital role in diabetes management, from early detection through biometric monitoring to continuous glucose tracking via wearables. Predictive analytics can identify individuals at high risk and support personalised intervention strategies. Additionally, real-world data from EHRs and mobile health apps inform population-level insights, helping public health authorities design more targeted prevention campaigns. However, gaps in healthcare access and health literacy, especially in low- and middle-income countries (LMICs), pose barriers to effective diabetes control. Ethical data governance and culturally tailored models are essential to ensuring equitable outcomes.

Cardiology addresses the diagnosis and treatment of heart and vascular diseases, including coronary artery disease, arrhythmias, heart failure and hypertension. Subspecialties such as interventional cardiology, electrophysiology, cardio-oncology and preventive cardiology reflect the field's complexity and scope. Data science enhances cardiology in multiple ways. Electrocardiogram (ECG) analysis using deep learning enables real-time arrhythmia detection.

Risk stratification models predict heart attack probabilities based on lifestyle, genetic and clinical data. Integration with wearable devices facilitates continuous cardiovascular monitoring and supports early intervention [35–50]. Moreover, AI-driven image analysis in echocardiography and cardiac MRI offers improved diagnostic accuracy. The integration of cardiology data from diverse sources—hospital records, mobile apps, imaging systems—into cohesive, interpretable models remains an ongoing challenge [44–50].

Ethical concerns regarding algorithmic bias, patient privacy and the transparency of predictive models must be addressed to foster trust in digital cardiology solutions. Each of the above domains represents a vital component of modern healthcare, and their integration with data science is reshaping how diseases are diagnosed, managed and prevented. This background underscores the interdisciplinary and data-intensive nature of contemporary health challenges, setting the stage for the methodological exploration of how advanced data science techniques can drive meaningful improvements across healthcare systems.

As ML and data science continue to evolve, it is imperative that healthcare professionals receive targeted training in these domains. Empowering clinicians and researchers with data literacy will be critical to fully leveraging ML's capabilities for enhanced patient care, informed policy-making and evidence-based medical innovation.

Discussions and Future Directions

To drive continued advancement in healthcare, the integration of bioinformatics, health informatics and advanced analytics is essential. This convergence enables the healthcare sector to better manage the increasing complexity, variety and volume of health data. Novel computational strategies and machine learning (ML) technologies are vital in transforming raw data into actionable insights that facilitate early diagnosis, effective treatment and personalised care.

The implementation of BDA has already yielded tangible benefits, from streamlining medical data management to accelerating drug discovery for complex conditions. As analytics technologies evolve, the emphasis is shifting from descriptive and diagnostic capabilities toward predictive and prescriptive systems. These systems are expected to forecast individual health trajectories by analysing longitudinal patient data and integrating insights from population-level health indicators. Such predictive models enhance preventive care, optimise resource allocation, and contribute to better clinical decision-making.

In public health, predictive modelling has proven particularly effective. ML algorithms have demonstrated high accuracy in forecasting disease outbreaks, thus enhancing preparedness and timely response. For instance, during the COVID-19 pandemic, AI-driven epidemiological models were used to predict viral spread and identify hotspots using real-time public health and mobility data. These models provided valuable input for policymaking and healthcare resource management, reinforcing the critical role of data science in mitigating global health crises.

In oncology, data science techniques have revolutionised cancer detection and treatment. Deep learning models, particularly convolutional neural networks (CNNs), have achieved remarkable success in analysing medical imaging data, such as mammograms and CT scans, to detect tumours with greater precision and fewer false positives. Additionally, genomics-based AI tools enable the identification of individual-specific genetic mutations, facilitating personalised medicine approaches. These advancements have led to more effective and targeted therapies, improving patient survival rates and quality of life.

Similarly, cardiology has benefited from predictive analytics, where ML models assess risk factors for cardiovascular diseases using time-series data from wearable devices and EHRs. These models support early intervention by identifying patients at high risk of heart attacks or arrhythmias based on a combination of clinical history, lifestyle behaviours and physiological metrics. Moreover, ML and artificial intelligence (AI) are transforming the drug discovery and clinical trial landscape. AI algorithms accelerate the drug development pipeline by analysing vast biomedical datasets to identify potential therapeutic compounds. The emergence of virtual clinical trials, enabled by remote monitoring and AI-driven data analytics, increases trial accessibility, reduces costs and enhances data accuracy. These innovations hold the potential to reshape the pharmaceutical industry and bring treatments to market more efficiently.

The predictive capabilities of ML are also enabling early detection of chronic conditions such as diabetes, hypertension and obesity. By analysing lifestyle factors, genetic predispositions and environmental exposures, ML models offer a holistic view of patient health and facilitate proactive care strategies. These developments emphasise the growing need for a patient-centred and data-driven approach in healthcare.

As the industry shifts from volume-based to value-based and personalised care, healthcare professionals must evolve accordingly. A robust understanding of data science and ML is increasingly necessary for clinicians, researchers and administrators. Training programmes and continuing education should emphasise data literacy, algorithmic transparency and ethical considerations in AI applications to ensure safe and effective technology adoption.

Future Directions

Looking ahead, several strategic directions should guide the future of health data science and machine learning in healthcare:

• Integration of multimodal data: Future systems must integrate data across genomics, imaging, sensor data, social determinants of health and behavioural data to create comprehensive patient profiles. This fusion will enable deeper insights and support the development of more precise predictive and diagnostic tools.

• Explainable AI (XAI): As ML models become more embedded in clinical workflows, ensuring transparency and interpretability is critical. XAI techniques will be essential for gaining clinicians' trust and facilitating responsible AI adoption in high-stakes environments.

• Federated and privacy-preserving learning: With the increasing demand for data privacy and compliance with regulations such as GDPR and HIPAA, federated learning offers a promising approach. It enables collaborative model training across institutions without sharing sensitive patient data.

• Equity and bias mitigation: Future ML systems must address issues of bias and health inequity. Ensuring diverse training datasets and applying fairness-aware algorithms are crucial to avoiding discrimination and ensuring equitable healthcare delivery.

• Cross-disciplinary collaboration: Advancing health data science will require closer collaboration between clinicians, data scientists, policymakers and ethicists. Such interdisciplinary efforts will ensure that technological innovations align with clinical needs, regulatory requirements and societal values.

• Continuous learning and adaptive models: Healthcare environments are dynamic. Models should be designed to learn and adapt continuously as new data becomes available, ensuring they remain accurate and relevant over time.

The ongoing integration of machine learning and BDA into healthcare systems is poised to transform patient care, medical research and public health strategies. Embracing these technologies with a focus on transparency, equity and collaboration will lead to more effective, personalised and resilient healthcare systems in the years to come.

Conclusions

This research has provided a comprehensive investigation into the convergence of advanced digital technologies—extended reality (XR), 6G, IoT, artificial intelligence (AI), machine learning (ML) and BDA —in transforming healthcare delivery, clinical decision-making and patient engagement. The findings confirm that these technologies are transitioning from experimental tools to essential components of modern digital healthcare infrastructure, with demonstrated impact in diagnostics, treatment, remote monitoring, surgical applications and medical education.

By leveraging XR systems (AR, VR, MR) integrated with ultra-fast 6G connectivity and IoT-enabled devices, healthcare providers can enable remote surgical interventions, immersive rehabilitation programmes, real-time diagnostics and interactive training platforms.

In parallel, AI and ML techniques have proven effective in early disease detection, predictive modelling and personalised treatment planning across cardiology, oncology and public health. The synergistic use of BDA with these technologies enables the extraction of actionable insights from heterogeneous datasets, including EHRs, genomic profiles and sensor-generated health metrics.

However, the effective and sustainable adoption of these technologies requires addressing critical challenges. Key issues include safeguarding sensitive patient data, achieving regulatory compliance (e.g., HIPAA, GDPR), ensuring interoperability between platforms, mitigating algorithmic bias and preventing misuse. These findings underscore the need for secure, ethical and user-centred digital health ecosystems supported by cross-disciplinary governance frameworks.

In alignment with these insights, this study identifies several priority areas for future research:

• Security and integrity: Deployment of advanced cryptographic methods and blockchain-based infrastructures to protect data confidentiality and ensure auditability.

• Ethical AI governance: Development of frameworks that address informed consent, fairness, transparency and accountability in algorithmic decision-making.

• Validated XR applications: Rigorous clinical evaluation of domain-specific XR solutions to ensure safety, efficacy and accessibility.

• Integrated AI-IoT pipelines: Large-scale implementation of AI-driven IoT ecosystems for real-time predictive analytics and precision healthcare.

Despite the promising outlook, limitations remain, including technical barriers to full interoperability, variability in digital readiness among healthcare institutions, and the need for substantial investment in infrastructure and workforce training. Addressing these challenges will require sustained collaboration among researchers, clinicians, engineers, policymakers and industry stakeholders.

A strategically designed, ethically grounded and securely implemented integration of XR, 6G, IoT, AI and BDA holds the potential to create a sustainable, patient-centric and data-driven healthcare ecosystem. Such an ecosystem can enhance operational efficiency, improve clinical outcomes and empower decision-making at every level of the healthcare continuum.
