Healthcare is very good at measuring failure.

We count deaths, admissions, incidents, and deterioration. We build evidence around crisis because crisis is visible, auditable, and uncomfortable enough to demand attention.

But what if the most important outcome in complex care isn’t recovery or even improvement but stability?

And what if we don’t yet have the language, the measures, or even the culture to evidence it?

The dominance of Evidence-Based Medicine has shaped what we recognise as knowledge. It shows what can be standardised, measured, and reproduced. That works well for predictable situations, but complex care doesn’t behave like that. Stability isn’t an endpoint, and it doesn’t follow a neat trajectory. It sits in the background, often unnoticed, because when things are working, we simply call it “business as usual”.

And that’s the problem.

We intuitively know what stability looks like. It’s when someone continues to engage, when behaviours don’t escalate, when relationships hold, when nothing breaks. It’s not dramatic. It doesn’t trigger alerts or thresholds. But in complex systems, that quiet continuity is often the difference between progress and collapse.

Yet culturally, we don’t value it. Crisis draws attention, funding, and urgency. Stability is expected, and so it becomes invisible. Even relational practice, widely accepted as fundamental is still difficult to define, measure, or prioritise in systems that are built around risk and outputs. As highlighted in The Heart of Practice: Building Cultures of Relational Care, relational work is recognised as essential, but remains marginal in policy and hard to operationalise because it is inherently complex and context-dependent .

The consequence is predictable. We design systems that respond to failure rather than sustain what is already working. Services become reactive, workforces fatigued, and individuals experience repeated cycles of escalation and breakdown. We end up investing heavily in crisis, while paying far less attention to what might prevent it.

What’s interesting is that the evidence isn’t entirely absent. It’s just not framed in the way we expect. It sits across relational practice, trauma-informed care and within psychological safety, community-based support and co-production. The relational care literature goes further, reminding us that care is not just something delivered in interactions, but something shaped by organisational culture, leadership, and the conditions in which people work and receive support .

This suggests a different way of thinking. Instead of asking what intervention works, we might ask what conditions allow stability to exist.

If we take that seriously, our idea of success begins to shift. It becomes less about discrete outcomes and more about sustained engagement and the lived experience of care. It is quieter, less visible work, but arguably far more important.

The challenge now is not to wait for perfect evidence, but to start naming and noticing stability in the systems we already run. To develop shared language, to use proxy measures where we need to, and to embed learning into practice. Perhaps most importantly, it requires a cultural shift to one that recognises that when things are going well, something important is happening, even if we are not yet measuring it.

Healthcare doesn’t lack evidence. It lacks evidence for the things that matter most in complex systems.

Stability is one of them.

And until we learn to see it, we will continue to build systems that only act once stability has already been lost.
