My sister needed blood to survive!

A donor had been identified, screened and cleared!

The system, at least on paper, was supposed to work!

But when the moment came, the blood that should have been available was not the one issued. What we received instead was a -3-week stored blood, unsuitable for her condition. Requests were made, explanations were given and still, nothing changed. It took escalation before the right decision was made.

That was the moment I stopped seeing healthcare as a set of policies and began to see it for what it really is: a system that either works when it matters or does not.

Long before that experience, I had been observing a quieter pattern. In clinical settings, across different levels of care, patients who required urgent blood transfusion often faced delays. Sometimes it was a matter of hours; sometimes it stretched longer. Yet Nigeria is not without structure. The country has a well-articulated legal framework guiding blood donation, including a clear prohibition of commercial donation and a strong emphasis on voluntary, non-remunerated systems in line with global standards.

And still, the gaps persisted.

The contradiction was difficult to ignore. It raised a question that would later define this study: what happens when a policy exists, but does not function in practice?

My sister’s illness brought that question into sharper focus. She was diagnosed with triple-negative breast cancer and as her chemotherapy progressed, she developed recurrent leucopaenia. Blood support became a recurring and urgent need. Given what I knew about the system, we chose family replacement donation, a decision rooted in both necessity and a desire for control in an otherwise uncertain situation.

What followed was not an isolated incident. Within the hospital environment, there were recurring whispers of similar experiences; instances where willing donors were declared incompatible, only for families to be subtly redirected toward alternative, often commercial, options. It was difficult to verify each case, but the pattern was hard to dismiss.

At some point, it became clear that this was no longer just a clinical concern. It was a system failure.

Most research on blood donation in Nigeria has focused on safety, particularly transfusion-transmissible infections. Those are important questions. But I was drawn to a different one, less explored, yet fundamental: are actual blood donation practices aligned with the legal framework designed to regulate them?

To answer this, I moved beyond assumptions and gathered evidence from multiple sources. A community-based survey of over 800 potential donors offered insight into knowledge, attitudes and willingness. A parallel survey of healthcare workers provided a window into everyday clinical realities. Hospital blood bank records grounded the findings in practice rather than perception.

What emerged was a picture that was both revealing and unsettling.

Awareness of the legal framework prohibiting paid blood donation was low. Many individuals were willing, at least in principle, to donate blood voluntarily. But that willingness rarely translated into consistent action. In practice, voluntary donation remained extremely rare, with the overwhelming majority of blood supply still coming from paid or replacement donors. The system, in effect, operates very differently from how it is designed.

The perspectives of healthcare workers added another layer of complexity. Delays in accessing blood were not unusual; they were expected. Some had witnessed patient outcomes worsen because blood was not available when needed. Others spoke of the practical impossibility of relying solely on voluntary donation within the current system.

This is where the tension becomes most visible. On one hand, the law prohibits commercial blood donation. On the other, the system continues to depend on it to function. It is not simply a case of people ignoring regulations. It is a reflection of a system under strain, one that adapts, sometimes in ways that are neither planned nor entirely ethical.

It would be easy to label this as non-compliance. But that framing misses something important.

What this research revealed and what my personal experience confirmed is that compliance cannot exist in a vacuum. It depends on capacity. It depends on infrastructure, supply chains, workforce and, perhaps most critically, enforcement. Where these are weak, systems evolve their own logic. They fill gaps in ways that may keep them operational, but not necessarily aligned with policy.

Revisiting the legal framework with this perspective was revealing. Nigeria does not lack policy. In many respects, the legal provisions governing blood donation are robust, clearly articulated, and aligned with international standards. The challenge lies elsewhere in implementation, enforcement and the absence of mechanisms that translate policy into everyday practice.

Looking beyond Nigeria, other countries offer useful lessons. China, for instance, once faced similar challenges with low voluntary donation rates and heavy reliance on alternative systems. Rather than enforcing an immediate shift, it adopted a phased approach combining regulation with incentives, public engagement and gradual system restructuring. Over time, this resulted in a significant transformation, with voluntary donation becoming the dominant model.

The contrast is instructive. It suggests that change in health systems is rarely achieved through policy alone. It requires time, adaptation and alignment between intention and reality.

For Nigeria, the path forward is unlikely to be simple. Strengthening blood donation systems will require rebuilding trust, improving public awareness, and creating structures that support and retain voluntary donors. It will require better data systems, clearer accountability and a more deliberate transition strategy one that recognises current dependencies while gradually reducing them.

More than anything, it will require a shift in how we think about policy not as an endpoint, but as part of a larger process.

This study changed how I see that process. It reminded me that health systems are not defined by what is written, but by what is done. And that the true test of any policy is not its intention, but its performance in moments of need.

Because when a patient is waiting for blood, policy is no longer theory. It is either life, or it is failure.
