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.
