What the evidence says about infrastructure reform
International research on emergency department reform is consistent on one point: physical improvements alone do not resolve overcrowding or sustainably improve performance. A systematic review of strategies to improve ED performance found that lasting gains require a combination of structural, operational and systemic changes, with physical redesign functioning as an enabler rather than a solution in itself. Studies examining ED overcrowding identify its primary drivers as inadequate triage systems, insufficient bed availability in inpatient wards, and the diversion of ED capacity to manage conditions that belong in primary care, none of which are resolved by renovation alone.
This last point is particularly relevant in the Greek context. Data from the Ministry of Health’s own electronic tracking system, currently operational in 10 hospitals, indicates that approximately 38% of patients presenting to emergency departments could have been safely managed in a primary care setting. This figure points to a structural issue that extends well beyond the ED itself: in many parts of the country, accessible and timely primary care remains inconsistently available, and the ED continues to function as the practical default point of entry into the health system.
A well-designed space creates the conditions for better care. The research evidence is clear, however, that it is the processes inside that space, including triage protocols, staff roles, patient pathways and digital integration, that determine whether those conditions translate into lasting improvement.
The organisational gap
The renovation of 63 emergency departments represents a significant capital investment. What the literature on health system reform consistently identifies as the harder and more consequential investment is the organisational one. Clearly defined and enforced triage protocols, fast-track pathways for lower-acuity presentations, structured integration with outpatient services and primary care, performance indicator frameworks with regular monitoring, and workforce planning aligned with new operational models are the interventions that determine whether physical improvements endure or gradually erode under the same systemic pressures that produced the original problems.
Change management research in healthcare settings adds a further dimension. Organisational reform in hospitals, particularly in high-pressure departments such as emergency care, faces significant implementation challenges, with studies estimating that up to 70% of organisational change initiatives in healthcare fail to achieve their intended outcomes. The most reliable predictor of success is not the quality of the plan, but the degree to which staff at all levels are involved in designing and implementing the change. This suggests that the renovation programme’s value will be substantially shaped by what happens in each facility after the physical works are complete.
A critical juncture
Greece’s investment in emergency department infrastructure arrives at a moment when the health system is also introducing a reinstated personal physician model, expanding primary care capacity, and rolling out digital health infrastructure across the NHS. These are complementary reforms, and their combined effect on ED demand will depend on how coherently they are implemented together.
The renovation programme has created a platform that did not previously exist. Whether that platform supports durable improvement in emergency care will depend on the extent to which the physical transformation is accompanied by the organisational, workforce and systemic changes that international evidence identifies as equally necessary.
The buildings represent a real and welcome change. The evidence suggests, however, that the more consequential work is still ahead.
