What an evidence-aligned model looks like in practice
Jason Vowles, Director — Program Performance
This is the fourth post in a nine blog series where Navigator Group will set out what we believe the current evidence tells us about psychosocial risk, recovery and workers' compensation, and where the open questions still are.
One of the biggest misconceptions in psychosocial risk management is that implementing a screening tool means you've implemented an evidence-based model. It doesn't. The evidence is increasingly clear that outcomes depend not on screening alone, but on what happens next.
In conversations with insurers, employers and scheme regulators, one question comes up repeatedly: what does an evidence-aligned psychosocial support model actually look like in practice? The It Pays to Care best practice guide makes a point that is easy to underweight: organisations that implement the full evidence-based model achieve substantial improvements in outcomes. Organisations that implement it partially often fail to achieve the expected benefits, or achieve significantly smaller gains. Screening alone, without effective matched care, does not improve outcomes. That finding has direct implications for how programs are designed and commissioned.
An evidence-aligned model cannot be assembled from components selected for ease of implementation. It requires a coherent clinical design, validated screening and assessment tools, appropriately skilled practitioners and genuine integration with the claims environment in which it operates.
The core components
An evidence-aligned psychosocial care model in workers' compensation has three functional layers that must operate together.
The first is systematic identification. Every worker entering the program is screened for psychosocial risk using validated tools, not as an administrative checkpoint but as the foundation for clinical decision-making. Screening is not diagnostic. It identifies workers at elevated risk of prolonged recovery and flags those who warrant a more detailed assessment.
The second is structured assessment. For workers who screen positive, assessment examines the specific barriers to recovery: coping style, workplace relationships, financial stress, pain beliefs, distress levels and self-efficacy. This information is used to design an individual care response. Assessment is not a one-time event. An evidence-aligned model requires outcomes to be measured, not assumed. Psychosocial risk should be reassessed throughout care, alongside functional recovery and return-to-work outcomes, allowing interventions to be adjusted as workers progress.
The third is matched intervention. The care delivered must correspond to the barriers identified. A worker whose primary barrier is workplace conflict requires a different clinical response than one whose primary barrier is catastrophic thinking about pain. Matched care is not a menu of available services. It is a clinical judgement, made by a skilled practitioner, about what is most likely to advance recovery for this individual.
Alongside these three layers, an effective model requires active integration with the claims environment. Case conferences with treating doctors, structured communication with claims managers and coordinated return-to-work planning are not optional additions. They are the mechanism by which individual clinical gains translate into durable outcomes.
The Navigator Support Program as an implementation example
Navigator Group's core model, the Navigator Support Program, is referenced as an implementation case study in the It Pays to Care best practice guide and reflects this architecture.
The program operates within workers' compensation schemes across the country, providing structured early intervention for workers at risk of prolonged recovery. Referral is often integrated with claims processes. Practitioners screen using validated tools, conduct structured psychosocial assessments and design individualised programs that address identified barriers across psychological, workplace and functional domains.
The guide identifies the Navigator Support Program as an example of a provider operating a full matched care model within a live scheme environment. It is a clinically structured, outcomes-monitored program rather than a generalised rehabilitation service.
The role of co-design
An evidence-aligned model is not only a clinical design. It is also an organisational commitment to treating workers as genuine participants in their own recovery.
Workers' Voice is clear that injured workers want to understand what is happening, to have goals they have been involved in setting and to experience the recovery process as something being done with them rather than to them. A model that reflects those principles is clinically different, not just procedurally different, from one that manages workers through a standard program structure.
That commitment to co-design is reflected in how Navigator approaches program development: grounding clinical models in the perspectives of the people they are designed to serve.
The conditions required
For a model of this kind to function, three conditions need to be present simultaneously: an insurer or scheme that has established a clear referral pathway, a service provider with genuine clinical fidelity to the matched care model and a claims environment that does not undermine the clinical intervention through adversarial processes.
When all three conditions are in place, the outcomes data is strong. When any one is absent, the model's impact is diminished. The next challenge for our industry is not understanding psychosocial risk, it is implementing models with enough fidelity that the evidence can be translated into consistent outcomes at scale. That requires collaboration between schemes, insurers and providers, but ultimately it is injured workers who stand to benefit most.
