Sustainment as Ongoing Implementation Work: Mechanism-Based Explanations for the Continued Delivery of a Mature Digital Rehabilitation Programme
This mixed-methods study of a mature digital neurorehabilitation programme in England identifies five interacting mechanisms—building workforce capability, fostering collaborative relationships, embedding delivery in systems, maintaining contextual fit, and constructing value—that explain sustainment as ongoing implementation work rather than a static outcome.

In the world of healthcare, launching a new treatment is often celebrated as a victory, but the true challenge begins the moment the initial excitement fades. This is the realm of sustainment, a concept that asks a deceptively simple question: how do we keep a complex service running effectively long after the starting gun has fired? Unlike a single medical procedure that ends when a patient is cured, a health service is a living system that must adapt to changing staff, shifting budgets, and evolving patient needs. For years, researchers have focused on what helps a program start, identifying factors like leadership or funding. However, there has been a growing realization that knowing what helps a program begin does not explain how it survives the slow, unglamorous work of daily routine. The question has shifted from what makes a program possible to how it actually stays alive over years, turning from a temporary project into a permanent part of the healthcare landscape.
This story comes from a large-scale study of a digital neurorehabilitation program called NROL, which helps people recover from strokes and other neurological conditions through online group sessions. The program had already been running for some time across two regions in England, delivering thousands of therapy sessions to hundreds of patients. The researchers behind this study were not interested in whether the program worked in the short term; they wanted to understand the invisible machinery that kept it going. They looked at two years of data, including records of every session held, documents from the hospitals and clinics involved, and the honest reflections of the staff who delivered the care. Their goal was to move beyond a simple list of success factors and instead uncover the specific processes that generate and maintain the program's existence in the real world.
What they found was that keeping the program alive was not a passive event where things simply continued on their own. Instead, sustainment was revealed as a form of ongoing work, a continuous effort to align the program with the people and systems around it. The study identified four core activities that staff and organizations had to keep doing to maintain the service. First, they had to constantly build the capability of their workforce. This meant more than just training staff once; it involved creating a culture where clinicians learned digital skills together, gained confidence in leading online groups, and supported one another as they adapted to new tools. Second, they had to actively build and sustain collaborative relationships. The program relied on a web of connections between different professionals and organizations, requiring constant communication and shared problem-solving to keep the network functioning.
Third, the program had to be embedded deeply within the existing systems of the healthcare organizations. This meant that the digital rehabilitation sessions were not treated as an add-on or a special project, but were woven into the standard referral pathways, scheduling systems, and job roles of the staff. By becoming a routine part of the daily workflow, the program reduced the burden on individuals and made delivery predictable. Fourth, the program had to maintain a fit with its changing context. The researchers observed that the program did not stay rigid; it adapted its group sizes, scheduling, and content to match the shifting pressures of the healthcare system while keeping its core purpose intact. These four elements worked together, reinforcing one another to ensure that the program remained relevant and deliverable over time.
However, the study also uncovered a fifth, cross-cutting process that tied everything together: the active construction and demonstration of value. The researchers found that for the program to survive, stakeholders had to continuously prove its worth to decision-makers. This was not just about showing that patients felt better, though that was part of it. The value was demonstrated across multiple dimensions: the clinical benefits for patients, the efficiency gains for the workforce, the organizational improvements in service delivery, and even the societal benefits of reducing travel and carbon emissions. In one region, this process of showing value led directly to the program moving from temporary pilot funding to permanent, recurring investment. The study suggests that value is not a fixed quality that a program simply possesses; rather, it is something that must be actively built, interpreted, and communicated to secure the resources and support needed for the future.
The researchers also noted that while the program succeeded in both regions, the path to success looked different in each place. In one area with more established infrastructure, the program relied heavily on being embedded in formal systems and receiving regular funding. In the other, which joined the program later, success depended more on strong relationships and the continuous effort to build evidence of value within local teams. This highlights that there is no single formula for keeping a health service alive; the specific mix of efforts required depends on the local environment. Furthermore, the study pointed out a persistent inequality: despite the digital nature of the program making it geographically accessible, patients living in more deprived areas were still less likely to start the rehabilitation. This suggests that while digital tools can remove some barriers, they cannot automatically solve the deeper structural issues that prevent equal access.
Ultimately, this research reframes how we think about the longevity of health interventions. It moves the focus away from viewing sustainment as a static outcome—a box to be checked after a successful launch—and instead sees it as a dynamic process of ongoing implementation work. The study concludes that keeping a complex service running requires a deliberate, continuous effort to develop staff skills, nurture relationships, integrate the service into daily routines, and constantly demonstrate its value to the wider system. By understanding these mechanisms, health leaders can better plan for the long term, recognizing that the work of keeping a program alive is just as critical as the work of starting it. The findings offer a practical roadmap for how digital health models, and indeed any complex intervention, can transition from a promising idea into a reliable, enduring part of everyday care.
