Digital Technologies as a lever for P4 Medicine   

The P4 Medicine paradigm aims to enable a holistic medical approach focused on proactivity rather than reactivity, prevention of diseases and prediction based on early identification and regression at the early stages rather than treatment, personalised and individual-oriented healthcare, and participation as everyone is responsible for optimizing their health and well-being. Such an approach requires generating a vast database of information on factors associated with patients’ health and disease through no other way than innovation and the implementation of new technologies that can tackle new priorities and multiple trends taking place under this new healthcare paradigm. A brief analysis of multiple technologies and potential solutions that these can bring to healthcare systems is depicted below:

Data Sciences

Data, especially Big Data, fuels medical research by providing raw material for establishing cause-and-effect rules, patterns, and exceptions. Big Data, which encompasses vast and complex datasets, is harnessed using Machine Learning (ML) algorithms and data scientists in healthcare and medicine. This approach enhances efficiency and accuracy in patient care. Examples of Big Data's applications include analyzing electronic health records for tailored treatments, utilizing population health analytics to identify trends and improve outcomes, and aiding drug development through clinical trial insights. The synergy between Big Data and cloud computing offers scalable and accessible data storage and sharing. Cloud computing is used in various healthcare aspects, such as storing medical records, remote patient monitoring, and streamlining clinical research. However, data security remains a concern, with potential solutions involving Artificial Intelligence (AI) such as ML, or blockchain. Additionally, data governance and standardization are emphasized as essential for aggregating diverse data types and protecting sensitive information while adhering to ethical standards.

Artificial Intelligence

AI is a learning-based process aimed at replicating human intelligence through applications, systems, or processes. The potential of AI is vast and can benefit patients, professionals, institutions, and public systems by different means including speech recognition, visual perception or language translation. In the medical industry, AI has the power to revolutionize diagnosis, reduce errors, prevent drug reactions, and offer personalized treatment plans, as it can help in data analysis, medical research or administrative tasks. Also, AI allows healthcare professionals to spend more quality time with patients, enhancing care and outcomes.

Although AI adoption in healthcare will require complementary innovation in regulation and ethics, the use of different branches of AI can surely increase productivity and efficiency of care delivery and offer a more personalised medicine. For instance, ML enables computers to develop learning models from data, improving disease detection from medical images, while Deep Learning (DL), using, for example, neural networks, can predict disease risks and treatment strategies, even providing personalized advice for chronic conditions. Machine vision focuses on optical and non-contact sensing technology for applications like posture analysis and hygiene detection. Natural Language Processing (NLP) could be seen as the branch of AI that enables computers to understand text and spoken language. NLP coupled with micro facial and body movement analysis can assist in navigating mental health issues like autism.

Digital trust and security

Health data is extremely vulnerable to hacking due to its sensitive nature, while building trust among patients, doctors, and institutions is crucial for effective data collection and treatment. This is why Cybersecurity and Cryptography are essential tools to secure health data. They can verify identities, protect privacy, ensure data integrity, and safeguard medical devices from malicious access. The emergence of quantum computers will soon request the evolution of these fields to maintain their effectiveness.

Biometry involves measuring physical characteristics for identification purposes. Although it is commonly used for security purposes in passports and access points, and for unlocking phones using fingerprints or facial recognition, the idea of creating a digital twin from a person’s biometric data including genetics, medical history and lifestyle is now gaining popularity in medicine. This way, such a digital twin could provide healthcare professionals with accurate patient information for better treatment decisions.

Distributed Ledger Technologies or Blockchain offers a shared and secure database that does not rely on a central authority. It can store and transfer patient data securely, track medical supplies, and automate various processes. Smart contracts on blockchain can simplify payment procedures, patient record-keeping, and administrative tasks, contributing to more efficient healthcare operations.

Digital engineering

Digital engineering approaches offer significant promise for advancing healthcare and medical practices through enhanced data analysis, efficient system design, and revolutionary computing capabilities.

High Performance Computing (HPC) and Data Analytics involves using specialized high-speed computing systems along with fast networks to tackle complex problems and process large amounts of data. Thus, high-performance data analytics (HPDA) leverages HPC and Big Data to analyze extensive datasets, revealing hidden trends and insights. This approach combines techniques to enable precise analysis. In healthcare, HPC and HPDA can optimize diagnoses, predict outcomes, personalize treatments, classify patients, and enhance medical systems.

Modelling and Simulation entail creating virtual environments for analysis and decision-making. In healthcare, the use of these technologies can predict patient outcomes, improve diagnoses and treatments, offer insights into disease progression, and design efficient medical systems. Future applications include simulating clinical trials, personalized treatments, and training environments for medical professionals.

System Engineering integrates engineering principles and problem-solving to design complex solution that can help to analyse, design, and optimize medical processes such patient record management software, data analysis systems and diagnostic tools.

Quantum Computing, based on quantum mechanics, processes information using qubits that exist in multiple states simultaneously. In healthcare, quantum computing offers transformative potential to facilitate complex disease modelling, develop personalized healthcare, accurate data analysis, and advancements in drug development, genetic sequencing, diagnostics, and quantum-based sensors in a drastically faster speed than traditional computers.

Digital infrastructure and the Internet of Medical Things (IoMT)

Digital infrastructure elements are revolutionizing healthcare by allowing remote real-time monitoring, correlating data with location, enhancing communication, and facilitating precise data collection through advanced sensor technologies.

Real-Time Monitoring can enable monitoring of patients' health metrics, such as CO2 levels, heart rate, and sleep quality. For instance, real-time data can trigger AI to identify issues and send notifications to adjust treatment. This efficient monitoring allows healthcare professionals to oversee multiple patients without an overwhelming increase in workload or even remotely, allowing chronic disease patients to be monitored from home.

Global Positioning Systems (GPS) technology allows devices that measure effort and track patients with conditions like Alzheimer's. GPS can help correlate biomarkers with location, contextualizing data. It is also used for detecting addiction triggers or tracking epidemics by analyzing the positioning of patients with the same illness. GPS-connected devices also assist in emergency interventions and locating patients.

Mobile Phone Technologies (5G) internet is crucial for transmitting data from monitoring devices to external servers. The power of 5G enables more autonomous devices and robots, enhancing connectivity and remote control.

Low Power Wide Area Networks & Low-Power Local Area Networks like LoRA, Bluetooth, and Zigbee enable communication between devices and are essential for IoMT applications. Their evolution supports medical devices' integration into various environments.

Distributed Sensors play a vital role in personalized medicine by measuring critical characteristics and supplying data. Some examples include sensors in watches to measure CO2 levels and dental plates aiding children with articulation disorders.
