- Theoretical Framework: Precision Medicine and Artificial Intelligence in Healthcare
2.1 Precision Medicine: Tailoring Treatment to the Individual
Precision medicine, also known as personalized medicine, is an approach that moves beyond the traditional disease-centric model to a patient-centric one. It acknowledges that individuals differ in their genetic makeup, environment, lifestyle, and the intricate interplay of these factors, which significantly influence their susceptibility to diseases, their response to treatments, and their susceptibility to adverse events. Key tenets of precision medicine include:
Genomics and Molecular Profiling: Understanding an individual’s genetic predispositions and the molecular underpinnings of their health and diseases.
Biomarkers: Identifying biological indicators that can predict disease risk, progression, or treatment efficacy.
Functional Phenotyping: Moving beyond observable characteristics (traditional phenotype) to analyze a broader spectrum of a patient’s data, including physiological function, metabolic status, cognitive abilities, and psycho-social factors. This captures a more dynamic and comprehensive picture of an individual’s health status.
Data Integration: The ability to integrate and analyze vast amounts of diverse data, from electronic health records (EHRs) to wearable sensor data, to create a holistic patient profile.
2.2 Artificial Intelligence: Unlocking Insights from Complex Data
Artificial intelligence, with its subfields like machine learning and deep learning, offers the computational power and analytical capabilities necessary to realize the full potential of precision medicine. AI algorithms can:
Analyze Big Data: Process and interpret massive datasets that are beyond human capacity, identifying subtle correlations and patterns.
Predictive Modeling: Develop models that can forecast disease onset, progression, or the likelihood of specific outcomes, such as falls or hospital readmissions.
Personalized Recommendations: Generate tailored treatment or intervention recommendations based on an individual’s unique profile and predicted risks.
Identify Novel Biomarkers: Discover new predictive or diagnostic markers that may not be apparent through traditional analyses.
Automate Processes: Streamline diagnostic processes and personalize treatment plans, freeing up clinician time for direct patient interaction.
- The JurongHealth Initiative: Methodology and Application
The JurongHealth Initiative at Ng Teng Fong General Hospital (NTFGH) and Jurong Community Hospital (JCH) employs a sophisticated integration of functional phenotyping and AI. The core of this project lies in the Jurong Ageing Resilience Project, a five-year undertaking designed to provide personalized care.
3.1 Functional Phenotyping: A Comprehensive Patient Snapshot
The project mandates a comprehensive functional phenotyping process for participating patients. This involves the meticulous collection and analysis of a wide range of patient data, encompassing:
Medical Data: Existing medical history, diagnoses, medications, laboratory results, and imaging data.
Psycho-social Data: Factors such as social support networks, mental health status, lifestyle habits (diet, exercise, sleep), and environmental influences that can significantly impact health.
Physiological Data: Objective measurements of physical capacity, such as gait speed, grip strength, and balance.
Cognitive Data: Assessments of cognitive function, memory, and executive abilities.
3.2 The AI Algorithm: Decade-Long Refinement for Predictive Power
Central to the initiative is an AI algorithm that has been developed and refined over the past decade using patient data specifically from JurongHealth Campus hospitals. This extensive historical dataset allows the algorithm to learn from a diverse patient population, enhancing its accuracy and generalizability. The algorithm performs the following critical functions:
Risk Stratification: Analyzes the collected functional phenotyping data to predict a patient’s risk of developing:
Physical Frailty: Characterized by decreased muscle mass, strength, and function (sarcopenia), leading to increased vulnerability and a higher risk of falls.
Cognitive Frailty: Deterioration in cognitive abilities, potentially impacting daily functioning and increasing the risk of dementia.
Metabolic Diseases: Such as diabetes, which are often linked to lifestyle and physiological factors.
Personalized Intervention Identification: Based on the predicted risks, the AI algorithm helps to identify specific, personalized interventions that can effectively target the identified risk factors.
3.3 Personalized Care Pathways: From Prediction to Prevention
The primary objective of this AI-driven analysis is to enable personalized care pathways that are proactive rather than reactive.
Targeting Physical Frailty: For patients identified with a high risk of physical frailty, interventions can be initiated before significant muscle loss occurs. This includes tailored physiotherapist-led exercise programs designed to build muscle mass, improve strength, and mitigate sarcopenia. This proactive approach can prevent falls, a major cause of morbidity and mortality in older adults, particularly after incidents like hip fractures.
Addressing Psycho-social Factors: The care team can also leverage the psycho-social data to identify and address factors that might negatively impact a patient’s nutritional status or overall well-being.
Improving Cognitive Health: Interventions aimed at maintaining or improving cognitive function can be implemented, with the ultimate goal of reducing the incidence of poor clinical outcomes, including hospital readmissions due to cognitive decline or related complications.
3.4 Shifting the Paradigm: From Reactive Treatment to Proactive Prevention
This approach represents a significant departure from the traditional healthcare model. Historically, if a patient presented with a hip fracture due to a fall, treatment would focus on managing the fracture itself. The new methodology, however, aims to prevent future falls by identifying individuals at risk and implementing targeted interventions to address the underlying frailty and risk factors. This not only leads to better health outcomes for the patient but also has the potential to significantly reduce healthcare costs associated with falls, hospitalizations, and long-term care.
- Beneficiaries and Project Timeline
The Jurong Ageing Resilience Project is projected to commence in the second quarter of 2026 and will extend over a five-year period. It is anticipated to benefit approximately 1,000 patients. Given Singapore’s demographic trends, a significant proportion of these beneficiaries are expected to be seniors. The report highlights that 300,000 residents in Singapore’s western region will reach the age of 65 within the next five years, underscoring the timely relevance of this initiative for an aging population.
