Kyoto, Japan -- Despite their crucial function, public hospitals often face limited resources and financial distress, and an aging population can further exacerbate any imbalances in medical resource distribution. Furthermore, the proportion of aging individuals is not uniform across the country; in Japan, this has led to regional disparities in healthcare for the elderly.
Previous studies suggest that restructuring public hospitals, though challenging, can alleviate the mismatch in healthcare resources. At least compared to private hospitals, it is more feasible to align public hospitals with regional needs. However, such studies often adopt qualitative approaches while lacking quantitative evidence to measure the effects of reorganization. This inspired a team of researchers at Kyoto University to examine the impact of public hospital restructuring on elderly hospital admissions in Japan.
"Many countries have reformed public hospitals to reduce resource imbalances, but there is limited information on the impact this has on communities and the regional healthcare system," says first author Kenji Kishimoto.
The team examined a particular restructuring case in a secondary medical service area in Japan, choosing an area with an aging and declining population. Before the reform, more than half of the elderly residents requiring hospitalization were admitted to hospitals in the surrounding areas due to the low capacity for acute care. The restructuring involved centralization of acute care, a decrease in total hospital beds with an increase in chronic care beds, and an increase in the number of doctors.
Using administrative claims data with statistical models, the team evaluated the effects of reforming on monthly hospital admissions. Their data included the hospital admissions of area residents aged 65 years or older within the period from 36 months prior to 48 months after the restructuring, a total of almost 59,000 hospital admissions. The researchers also took the number of hospital admissions in nearby areas into account, enabling them to understand wider trends more comprehensively.
The results revealed that after restructuring, the number of monthly admissions within the area increased noticeably, reaching the same level of admissions at hospitals outside the area. These findings suggest that the reforms helped improve the local capacity for elderly hospital admissions and also enabled more efficient bed utilization and management, as the total number of beds actually decreased.
This study highlights the importance of examining hospital admissions within the community when assessing the impact of public hospital restructuring. Future inquiry could evaluate changes in patient-oriented outcomes -- such as the quality of care -- that follow hospital restructuring, while also considering accessibility and socioeconomic variables.
