Key Takeaways

• Graphnet Health’s population health analytics now supports nearly nine million patients in England, improving early intervention and reducing emergency care reliance.
• Embedding the Johns Hopkins ACG System enables NHS teams to identify rising health risks, optimizing patient care pathways.
• Proactive care initiatives in East Kent resulted in a significant 69% drop in emergency department visits and a 70% reduction in admissions for complex care patients.

Population Health Analytics Enhancing Patient Care

Graphnet Health has successfully integrated its population health analytics systems to serve nearly nine million patients in England, facilitating improved early intervention strategies and minimizing the need for emergency care. By utilizing the Johns Hopkins ACG System methodology, about one in six patients is now identified and analyzed, allowing for systematic decision-making within integrated care systems (ICSs), NHS trusts, and primary care organizations.

Dr Priya Kumar, leading primary care initiatives, noted the complexities of urgent care systems. The integration of the ACG System segmentation tool enhances clinicians’ understanding of their patients, ensuring that individuals are seen by the appropriate healthcare professionals on their first visit. This streamlines the care process, enabling better allocation of time and resources, ultimately leading to enhanced patient outcomes.

In East Kent, a year-long proactive care program targeted at individuals with frailty and complex health needs yielded impressive results. Emergency department visits decreased by around 69%, while hospital admissions for this group fell by about 70%. Patients participating in the program reported feeling more confident in managing their health and expressed greater satisfaction with local healthcare services.

Dr Sarah Phillips, Chief Medical Officer at Kent Community Health NHS Foundation Trust and a senior lead for the program, emphasized the program’s effectiveness in empowering patients and reducing hospital dependency. This aligns with the broader shift towards community-based healthcare.

At the systemic level, Frimley ICS has utilized the Johns Hopkins Patient Need Groups segmentation model to analyze urgent and emergency care data. The findings revealed that approximately 15% of emergency department visits involved minor health issues among specific patient groups, indicating significant opportunities for earlier care interventions, which could further reduce acute care reliance.

In addition to emergency care advancements, Graphnet’s population health analytics are transforming operational practices in primary care. GP practices are applying ACG-based segmentation to improve triage processes and safely prioritize urgent cases. This ensures that patients are directed to the most suitable clinician on their first attempt, enhancing overall healthcare efficiency.

To further support remote health monitoring, Graphnet announced a partnership with Luscii in October 2025 to launch Graphnet Remote Monitoring—a platform designed to merge remote monitoring with population health and shared care records, fortifying patient support within the community.

In summary, the strategic implementation of population health analytics by Graphnet Health is revolutionizing patient care within the NHS, improving early detection of health risks, and significantly reducing emergency healthcare burdens, while fostering a patient-centered approach to health management.
