Abstract: Objective The aim of this study was to examine the trend of maintenance hemodialysis (MHD) patients across the administration district for hemodialysis in recent years in Beijing area. Methods The patients’data were obtained from the Beijing Hemodialysis Quality Control and Improvement Center (BJHDQCIC) in the period from 2007 to 2013. Patients with unknown residential address or unclear location of dialysis unit were excluded. The trend of MHD patients across the administration district for hemodialysis was evaluated by comparing residential address and the location of hemodialysis unit. The specific burden of hemodialysis for an administration district was assessed by the ratio of dialysis patients and the patients living in this district, and the ratio of dialysis patients and hemodialysis equipment number in this district. Results A total of 9,591 patients met the inclusion criteria, and 34.28% of the patients moved across the administration district for hemodialysis (resident address and hemodialysis unit were not in the same district). Hemodialysis treated in the central areas of Beijing was found in 44.62% patients living in the inner suburbs, and 12.23% patients in the outer suburbs. Patients from suburbs for hemodialysis increased the burden of hemodialysis units in the central areas. In the urban districts of Hai Dian, Xi Cheng, Chao Yang and Dong Cheng, the ratio of dialysis patients and the patients residing in this district was 2.37, 1.61, 1.29 and 0.93, respectively, and the ratio of dialysis patients and equipment number was 3.19, 4.57, 3.61 and 3.06, respectively. Conclusion More than one- third MHD patients moved across the administration district for hemodialysis. Most of them were from the suburbs to the central districts of Beijing, which increased the burden of hemodialysis units in the central areas.
