After waiting lists pushed Denmark’s public health system to breaking point in the mid-2000s, the country’s first instinct was to build more hospitals. Nearly two decades on, former Healthcare Denmark chief Hans Erik Henriksen says the harder, more important work was deciding where care should happen at all.

Hans Erik Henriksen has spent two decades watching health systems try to outrun demand. As the former chief executive of Healthcare Denmark for eight years, and now vice president of QUMEA, a company building radar-based patient monitoring technology, he has had an unusual vantage point: leading a national health system through major reform, then helping build the technology meant to support whatever comes next.

That tension, between systems designed to react and the chronic, ageing demand they now face, runs through Henriksen’s account of Denmark’s reform journey. It is also, he argued, a caution for any country tempted to think it can build its way out of the problem.

When Waiting Lists Became a Crisis

By the mid-2000s, cracks were showing in Denmark’s free, tax-funded health system, in which regional health authorities, not the national government, own and run every public hospital. Fixed budgets meant nothing automatically scaled to match demand, and waiting lists grew. The government’s first response, a guarantee letting patients go private once they had waited too long, mostly succeeded in revealing how expensive the underlying problem really was.

Rather than let politicians design the fix, an independent expert committee was given the job: work out what needed to change, publish the recommendations, then let political agreement follow the evidence. “If you want to change things and really make reform,” Henriksen said, “don’t let the politicians do it.” The approach reshaped Denmark’s health geography. Thirteen counties became five regions. Two hundred and seventy-one municipalities consolidated into 98. And hospitals lost their general remit: where almost any hospital could once treat almost anything, each was now specialised, and patients needed to know which one did cancer, which did orthopaedics, which did trauma.

The hospital count fell from 78 to 28, spread across around 60 physical sites, with 16 of those built entirely new as part of a hospital construction program costing in the order of €7 billion. When Germany later commissioned a study into whether to follow Denmark’s lead, researchers put the equivalent cost there at roughly €320 billion. Germany is now pursuing a more modest version of the same approach.

A Reform That Solved One Problem and Quietly Created Another

By most measures, the first wave of reform worked. Hospital productivity rose 30 per cent between 2007 and 2017, meaning the same money treated nearly a third more patients. The waiting list emergency that triggered the whole exercise had disappeared by 2010. Emergency departments were consolidated from 41 to 21, reducing the number of acute hospitals by 46 per cent and putting senior specialists on the floor rather than junior doctors learning on the job. Ambulance crews were retrained and equipped to stabilise patients and route them to the hospital best equipped to treat them, not simply the nearest one.

But the reform’s central bet, that freeing up hospital capacity would be matched by growth in primary and community care, did not fully pay off. Municipalities were handed responsibility for rehabilitation and community health without the funding incentives to build the capacity that required, and general practitioners, meant to anchor the system as the entry point for almost all care, were never properly brought into the new model. By around 2020, the productivity gains had stalled, and average hospital length of stay, which had been falling for over a decade, started creeping back up. The system that fixed Denmark’s waiting lists had quietly built a new bottleneck.

Moving the Centre of Care Closer to Home

Denmark’s response, now mid-way through its second wave of reform, is to stop treating the hospital as the default setting for care and to invest seriously in the alternative. GP numbers are being expanded by 40 per cent, with GPs given clearer control over patient pathways, building on dedicated fast-track pathways Denmark introduced for cancer some years ago. Home nursing and acute treatment, previously run unevenly across 98 municipalities, is being consolidated under the same five regions that already run the hospitals, so that one clinical authority is accountable wherever care is delivered.

The clearest evidence that this shift can work, Henriksen said, came from a study of 300 patients with chronic obstructive pulmonary disease. Half were treated conventionally. The other half were taught to monitor their own symptoms using a simple toolkit, with a structured response plan and a specialist nurse on call whenever their readings flagged a problem. The results were striking: a 56 per cent reduction in hospital admissions, a 78 per cent reduction in GP visits, and close to 50 per cent net savings on the cost of caring for that group of patients. What drove the result, Henriksen was careful to stress, was not the technology but the model behind it: patients who understood their own disease well enough to act early, backed by a system organised to respond fast when they did.

Technology as the Enabler, Not the Strategy

It would be easy to read Denmark’s shared health record, national medicine database and citizen-facing apps as the real story here. Henriksen argued the opposite: the technology only works because it sits on top of a deliberate model of care, not the other way around. Denmark’s digital foundations go back almost 30 years, to a 1994 analysis that found doctors and nurses were losing 30 per cent of their working time chasing paper records. The citizen portal that followed gave every Dane secure, direct access to their own clinical record, referrals and prescriptions well before most countries considered the idea. The same logic now applies to Denmark’s personalised medicine strategy, where the order of priorities is deliberate: governance, ethics, data protection and clinician knowledge come before the genomics and AI capability they are meant to support.

It is also, not coincidentally, the model behind Henriksen’s current work at QUMEA, where radar sensors track patient movement and vital signs in hospital and aged care settings without cameras or wearables. The technology is sophisticated. The pitch, consistent with everything else in his account of Danish reform, is that it exists to support a particular kind of care, not to replace the thinking about what that care should look like.

Practical Takeaways

•        Capacity is not a strategy. More or bigger hospitals can buy time, but without matching investment in primary and community care, the gains erode within a decade.

•        Depoliticise the structural decisions. Denmark’s most disruptive reforms were designed by an independent expert committee, with politicians agreeing to recommendations rather than authoring them.

•        Get the incentives right the first time. Denmark’s biggest reform gap, primary care capacity, traces back to handing municipalities responsibility without the funding incentives to build it.

•        Equip patients before monitoring them. The COPD pilot’s results came from patient education and a responsive clinical model; the technology was the delivery mechanism, not the intervention.

•        Treat digital infrastructure as a decades-long investment. Denmark’s data foundations were laid 25 years before they paid off in personalised medicine and integrated records, and they continue to compound in value.

Where Denmark Goes From Here

Denmark is not finished. Its current reform wave is still working out how much authority to hand to its new regional health councils, GP numbers will take years to lift, and Henriksen concedes the structure agreed in 2024 was a political compromise rather than the cleaner model experts recommended. But the broader lesson holds for any health system facing the same combination of an ageing population, rising chronic disease and a fixed public budget: the answer was never going to be more hospitals. As Henriksen put it, the ambition is simply to deliver care “at the lowest effective cost, and that’s probably in the home.”
