Geographic equity in community rehabilitation service capacity in Shanghai, China: a five-year entropy-weighted TOPSIS study
This five-year study of Shanghai's community rehabilitation centers reveals that while the demonstration-centre programme significantly improved service capacity, persistent disparities between administrative districts—rather than urban-suburban divides—highlight the need for targeted municipal support and stable investment to achieve true geographic equity.

Rehabilitation is not merely a final step after an illness; it is a vital bridge that helps people recover from injury, manage long-term conditions, and return to their daily lives. For this bridge to be useful, it must be accessible to everyone, regardless of where they live. In large, complex cities, the challenge is not just building enough facilities, but ensuring that the quality of care is consistent across every neighborhood. If a city claims to have a strong rehabilitation system, that claim must hold true whether one lives in the bustling city center or in the quieter suburbs. Researchers in Shanghai, China, set out to test this reality. They wanted to know if a new government program designed to upgrade local rehabilitation centers was actually working, and whether the benefits were being shared fairly across the city's different districts.
To answer these questions, a team of researchers from hospitals and health commissions in Shanghai conducted a five-year study, tracking the performance of 48 community rehabilitation centers from 2020 to 2024. They focused on six specific districts: Fengxian, Jiading, Jing'an, Minhang, Putuo, and Xuhui. The team did not rely on simple counts of equipment or staff; instead, they built a comprehensive picture of how well each center operated. They looked at everything from the availability of medical tools and the training of therapists to the number of patients treated and the success of home-based care services. To make sense of this vast amount of information, they used a method that weighs every factor objectively, allowing them to rank each center's overall ability to provide care on a single scale. This approach let them see not just if centers were getting better, but how the improvements compared across different areas.
The study revealed a clear story of progress, but also of uneven ground. Centers that were selected to participate in a special municipal demonstration program showed a distinct improvement in their ability to deliver care. Before the program began, these centers had an average performance score of 0.27. After receiving support, which included better equipment, specialized training, and technical help from larger hospitals, their average score rose to 0.30. This change was statistically significant and substantial. In contrast, the 16 centers that did not participate in the demonstration program saw only a tiny, statistically insignificant bump in their scores, moving from 0.20 to 0.22. This suggests that the specific package of support provided to the demonstration centers was effective, while general improvements across the city were much slower.
However, the most revealing part of the study was what happened when the researchers looked beyond the simple divide between "city" and "suburb." A common assumption is that urban centers are well-resourced while suburban ones struggle. When the researchers compared the urban and suburban centers as broad groups, they found no significant difference in performance at any point during the five years. The averages looked similar. Yet, when they zoomed in to look at the individual districts, a different picture emerged. The city was not a uniform block of progress; it was a patchwork of distinct trajectories. The Jing'an district consistently maintained the highest performance, ending the study with a score of 0.34. At the other end, the Fengxian district started with the lowest score of 0.17 and, despite some improvement, remained the lowest-performing area with a score of 0.22 in 2024. The gap between the best and worst districts persisted throughout the entire study period.
One district, Putuo, offered a particularly instructive case. It started the study with strong performance, even outpacing Jing'an in the early years. But after 2022, its progress stalled and became unstable. The data showed that while Putuo had invested heavily in equipment in 2021, that investment dropped by more than half the following year. The number of patients receiving rehabilitation at home, a critical service for those with mobility issues, fluctuated wildly, peaking in 2022 before falling sharply. This volatility suggests that having a high average score can sometimes hide underlying instability in how services are managed and funded. The researchers noted that without looking at the specific details of each district, these fluctuations would have been invisible in a city-wide average.
The findings challenge the idea that building more centers or setting city-wide standards is enough to ensure fairness. While the city-wide standards helped raise the floor for everyone, they did not eliminate the deep differences between districts. The study suggests that true equity requires more than just a general plan; it demands targeted support for districts that are lagging, such as Fengxian, and stable, long-term funding to prevent the kind of volatility seen in Putuo. The researchers conclude that while the demonstration program was a success, the path to a truly fair rehabilitation system in a megacity like Shanghai requires a more nuanced approach. Policymakers must look beyond the broad averages and address the specific needs and challenges of each local community to ensure that the quality of care does not depend on one's postal code.
