The NHS is sustained less by the strength of its systems than by the commitment of the people who work within them. From reception staff to clinicians, it is increasingly clear that day-to-day care is delivered not because the system functions well, but because individuals absorb its failures through effort, improvisation, and goodwill.
This is not a sustainable equilibrium. Across the service, the gap between what the system demands and what it can reliably deliver is widening. Technology, rather than relieving pressure, often compounds it, increasing administrative burden, fragmenting workflows, and diverting attention away from care. The consequences are felt not only by staff, but by the millions of patients who depend on the system at moments of acute vulnerability.
And yet, this trajectory is not inevitable. For the first time in decades, shifts in technology and capability make it possible to imagine a health system that can live with its own complexity rather than be overwhelmed by it - if the system is willing to change.
What follows is not a critique of intent or effort, but a diagnosis of structure. The NHS is under strain not because it lacks capable people or worthy aims, but because it has become constrained by forces that now exceed its capacity to adapt. Understanding those forces is a prerequisite to changing them.
Here is my diagnosis of the NHS’s core problem: it is a system constrained by complexity - not complexity that is inherent and unavoidable, but complexity that has compounded over time.
Roughly every five years, successive governments repeat a familiar cycle:
Viewed in isolation, this approach appears reasonable. Each intervention is typically motivated by genuine failures and designed with good intentions. The problem lies not in any single reform, but in what happens when such reforms accumulate.
Healthcare is inherently complex because people are complex. The system is tasked with managing human health - a biological and social phenomenon of extraordinary intricacy - under conditions where the worst-case outcome is death. This creates a profound asymmetry of risk: the cost of getting things wrong is morally, politically, and emotionally intolerable. From this asymmetry emerges a strong aversion to failure. In response, politicians and bureaucrats attempt to bound risk through rules, regulations, targets, and oversight.
The system increasingly seeks to abstract away uncertainty by codifying behaviour: specifying processes, defining acceptable actions, and reducing discretion wherever possible.
The NHS is not failing despite increasing regulation and oversight, but partly because of it. In complex moral systems, each attempt to reduce risk or impose control increases systemic complexity, which in turn generates new failures that demand further intervention. The result is a self-reinforcing cycle in which management replaces judgment, bureaucracy replaces care, and stability is purchased at the cost of adaptability.
What begins as an effort to make the system safer ultimately makes it more rigid, slower to learn, and less adaptable, thereby increasing the very risks it was designed to contain.
A downstream effect of compounding institutional complexity is technological stagnation and a severe talent selection problem. As regulatory, procurement, and organisational constraints accumulate, healthcare becomes an environment in which iteration is slow, risk is asymmetric, and success depends more on institutional navigation than technical excellence. Unsurprisingly, many capable technical entrepreneurs conclude that healthcare is simply ‘too hard’ and redirect their efforts toward sectors such as B2B SaaS, where systems are more legible, decentralised, and meritocratic (I was one of these people).
This withdrawal of high-leverage talent further reduces competitive pressure within healthcare, allowing legacy technologies and vendors to entrench themselves. In the absence of credible disruptive threat, complexity and obsolescence compound rather than reset, reinforcing the very conditions that deter innovation in the first place.
