Risk Stratification and Prioritisation

Frailty identification is only the first stage of population health management. Once people living with frailty become visible across a neighbourhood population, the next challenge is identifying who is most at risk of deterioration and may benefit from earlier intervention.

As frailty progresses, the risk of hospital admission, functional decline, loss of independence, and mortality increases significantly. However, deterioration is rarely sudden or unpredictable. In many cases, warning signs emerge long before crisis occurs.

These warning signs are already visible across health and care systems every day, including:

• Falls and fractures
• Increasing ambulance use
• Emergency department attendance
• Repeated hospital admission
• Mobility decline
• Malnutrition
• Polypharmacy
• Delirium
• Carer strain
• Clinician concern

Viewed in isolation, these may appear to be separate clinical problems. In frailty, they often represent the cumulative effects of worsening biological, functional, psychological, and social vulnerability.

A fall illustrates this clearly. What appears to be a single event may actually reflect multiple interacting pressures becoming visible simultaneously:

• Biological: Muscle weakness, medication effects, worsening long-term conditions
• Functional: Reduced mobility, impaired balance, difficulty with activities of daily living
• Psychological: Cognitive impairment, low mood, fear of falling
• Social: Isolation, limited support, unsafe living environments, carer strain

The challenge is not a lack of deterioration signals. Health and care systems already generate large amounts of information associated with rising frailty risk across general practice, ambulance services, community teams, emergency departments, acute trusts, and social care every day.

The problem is that these signals are often captured, interpreted, and acted upon in isolation within the service that generated them rather than accumulated over time into a shared understanding of worsening frailty over time.

As a result, patterns of deterioration that may be clinically significant at neighbourhood population level can remain fragmented across organisational and professional boundaries until crisis, hospital admission, or major functional decline finally brings them together.

This is where risk stratification and prioritisation become critical.

At Target Health Solutions, we believe effective prioritisation depends on connecting deterioration signals longitudinally across neighbourhood systems so that rising frailty risk becomes visible before crisis develops.

General practice remains central to this process because it is one of the few places where information from across the system is continuously brought together over time.

This includes:

• Continuity through repeated patient contact over months and years
• A dynamic frailty register linked to the registered population
• Clinical correspondence flowing in from community, acute, ambulance, and urgent care services
• A continuously updated longitudinal clinical record

Together, this allows isolated deterioration signals that may appear insignificant on their own to be brought together into a clearer picture of rising frailty risk across neighbourhood populations.

When prioritisation functions effectively:

• Deterioration can be recognised earlier
• Intervention becomes more proactive
• Avoidable escalation and hospital admission may be reduced
• Care becomes more coordinated around the individual over time

Once rising risk has been identified, the next challenge is coordinating effective multidisciplinary intervention around the individual.

This is where Comprehensive Geriatric Assessment, continuity of care, and Integrated Neighbourhood Team delivery become critical.
