In early July 2026, Amsterdam city councillors reacted angrily to reports that patient care would eventually leave the VUmc site, after Amsterdam UMC had announced a proposed decision to concentrate patient care at the AMC location by 2040. Earlier in the year, councillors had understood from the board that VUmc would not close as a location.
The issue was not simply whether a building would remain in use. The governance issue was the perceived gap between earlier reassurance, strategic intent and what stakeholders later understood the operational reality to be.
That gap is not only a communication issue. It is a warning sign at the interface between board decision and organisational reality.
Amsterdam UMC is not a simple example of cooperation replacing merger. It is a merged organisation making a long-term concentration decision. But the case is still instructive. It shows a governance challenge that also runs through Dutch hospital cooperation: multiple sites, regional dependencies, stakeholder expectations and operational consequences do not always move at the same pace.
Mergers have become harder. Cooperation has intensified.
For several years, Zorgvisie and other sector observers have pointed to the same pattern: large hospital mergers have become harder and less common, while cooperation has intensified.
Oncology networks, regional acute-care structures, shared specialist training, ZBC partnerships — hospitals are increasingly integrating their work without legally consolidating their organisations.
This is not a temporary phase. It reflects real constraints: stricter scrutiny of mergers, stakeholder concern about scale, and the practical reality that many forms of care coordination do not require common ownership to function.
The cooperation model is here to stay.
For boards, cooperation can look attractive. It is more flexible than merger. It preserves identity. It avoids some of the political friction of consolidation. It can be built incrementally, without forcing every decision into one institutional structure.
Those are genuine advantages.
But cooperation also creates a governance problem that merger, for all its difficulty, does not. It leaves accountability distributed across organisations with different boards, different cultures, different incentives and different views of who is responsible for what.
The interface is where governance breaks down
In a merged organisation, the question of who decides, who escalates and who owns outcomes is at least answerable in principle. There is one governance structure, one board and one accountability chain.
That does not mean the answer is always clear in practice. But there is a single place to look.
In a cooperation network, that clarity does not exist by default.
When an oncology network must decide how to allocate scarce capacity between partner hospitals, who makes that decision?
When an escalation is needed across organisational boundaries, who receives it?
When a patient outcome falls below standard at the interface between two cooperating organisations, who is accountable?
These are not theoretical governance questions. They are the questions that become visible in incidents, inspections and public credibility crises — usually after the fact.
Regulators and public reporting are also making governance more visible. In youth care, IGJ can enforce legal requirements for internal supervision from 1 July 2026. In acute care, SEH availability, reachability and visitor numbers are becoming more transparent. NZa has recently fined a healthcare insurer for insufficient transparency during the procurement process.
These examples come from different parts of the system. But they point to the same development: governance, transparency and execution are becoming more inspectable.
What boards may not see through their usual oversight instruments, regulators and public reporting are increasingly making visible.
The governance gap in cooperation networks is not invisible. It is simply located where most board oversight instruments do not look: at the interface between organisations, in the transition zone between one leadership hierarchy and another.
What boards typically see — and what they miss
Most board oversight in cooperation networks relies on familiar instruments: management reports, quality dashboards, incident reviews and periodic partner consultations.
These instruments are useful. But they were designed mainly to surface what is happening inside an organisation. They are much less effective at detecting what happens at the boundary between organisations.
A hospital board may have good visibility into its own executive layer's assessment of a network partnership. It will rarely have structured insight into how operational staff on both sides of that partnership experience ownership, authority and escalation.
That difference matters.
The gap between what the board believes the cooperation delivers and what those executing it experience is precisely where network governance risk accumulates.
A similar mechanism appears to be visible in the VUmc situation: not a deliberate misrepresentation, but a failure to surface the distance between board-level confidence and operational reality.
Three questions every board in a cooperation network should be able to answer
The question is not whether your organisation participates in networks that create interface risk. In Dutch healthcare in 2026, the answer is almost certainly yes.
The question is whether your board has the instruments to see where that risk is strongest.
Three questions provide orientation.
First, where in your cooperation network do perceptions of ownership, authority and escalation diverge most significantly between the executive layer and the staff who operate at the interface?
A consistent answer at board level does not mean a consistent reality on the ground.
Second, at which transition — between your organisation and a partner, or between layers within your own structure — does strategic alignment break down?
That is where decisions stop travelling reliably and where execution risk accumulates.
Third, which governance risks in your network are reinforcing each other?
Workforce scarcity, unclear role division and weak escalation routes do not operate independently. Where they coincide, they compound.
These questions cannot be answered from management reports alone. They require an independent measurement of how accountability, authority and escalation are experienced across each layer of the organisation and across the network.
Cooperation is not the problem
The shift from merger to cooperation is not a governance failure in itself.
Networks can deliver real value: more flexible care, stronger regional coordination and better use of scarce specialist capacity.
In June 2026, IGJ reported after visits to seven oncology care networks that professionals were strongly committed to suitable care and support, while the organisational and financial basis underneath the networks remained vulnerable. Without clear governance, shared ownership and structural financing, the inspectorate warned, these networks cannot be made sustainable.
That is the point.
The clinical logic of cooperation may be strong, while the governance underneath it is still incomplete.
A cooperation agreement does not automatically align leadership hierarchies. It does not make accountability clear at the interface. It does not tell either board where risks are concentrating.
Network care does not remove hierarchy. It makes accountability harder to see — and harder to assign when something goes wrong.
The boards that will navigate this well are not necessarily the ones with the most sophisticated cooperation agreements. They are the ones that can answer, with evidence, where accountability weakens across the layers of their network — before a regulator, a councillor or a public incident answers that question for them.
Author's note: I write from the perspective of organisational governance, not as a hospital insider. My work focuses on how strategic intent, authority and accountability move through complex organisations and networks. Dutch healthcare is a clear example of a broader governance challenge: when execution depends on cooperation across boundaries, boards need better visibility into where accountability weakens.
