The future of healthcare lies not only in treating disease, but in understanding and addressing the interconnected determinants of health
The biomedical model does not need replacing. It needs expanding.
Modern medicine has transformed human health through extraordinary advances in infectious disease, surgery, acute care, diagnostics and pharmacology.
Some persistent conditions, however, cannot always be adequately explained or treated through structural pathology alone. Research increasingly shows how the nervous system, immune system, behaviour, environment, stress and perception can influence real physical symptoms and recovery.
This is particularly relevant to some forms of chronic primary pain and functional symptoms, where altered nervous-system processing may contribute to symptoms even when ongoing tissue damage does not fully explain their severity. This does not mean that symptoms are imagined or psychological. It expands the range of evidence-based tools available to patients and clinicians.
Evidence remains stronger for some conditions and interventions than for others. Healthcare systems should remain open to nervous-system-informed and multidisciplinary approaches where supported by rigorous research. The strongest model of care will combine the strengths of biomedical and biopsychosocial approaches.
Healthcare systems appear to be systematically underinvesting in interventions that create greater long-term health and economic value.
Chronic disease prevalence and demand for care are rising as populations age and major risk factors continue to place pressure on health systems. Yet most healthcare expenditure still occurs after disease has developed, while comparatively little is directed towards prevention and primary care.
The consequences extend beyond healthcare budgets. Chronic illness contributes to disability, reduced labour-force participation, lost productivity and diminished quality of life. These costs often accumulate gradually and fall across different parts of society, making preventive investment harder to prioritise than immediate treatment.
Effective prevention can include healthier environments, early identification of risk, behavioural interventions and stronger primary care. Not every illness can be prevented, but healthcare systems should invest where credible opportunities exist to improve long-term health trajectories and reduce avoidable costs.
Healthcare should be judged by the recovery, capability and wellbeing it creates.
Alongside my wider work in development finance and sustainability, I contribute as Head of Telos at Rypple, where I explore how prevention, health impact modelling and evidence-based innovation can support better decisions.
Ultimately, my interest lies in a simple question: how can societies allocate scarce resources in ways that create the greatest long-term value for people?
Whether in healthcare, impact finance or public policy, I believe institutions should evolve with the evidence and remain focused on the wellbeing they create.
