Abstract: 【Abstract】Objective To improve the overall serum phosphorus (P) compliance rate in Wuhan based on the data feedback from Wuhan Hemodialysis Quality Control Center platform. Methods A total of 3,794 hemodialysis patients from 44 hemodialysis centers in Wuhan in the period from January 2018 to January 2019 were selected as the research subjects. The data feedback from Wuhan Hemodialysis Quality Control Center platform were used to calculate the serum P examination and compliance rates. After repeated evaluations and renovations for one year, serum P examination and compliance rates were rEcalculated and compared with the previous rates. Results ① Serum P and parathyroid hormone (PTH) levels decreased (F=11.976 and 10.414 respectively; P<0.001 and =0.015 respectively), and serum calcium (Ca) increased (c2=119.725, P<0.001). ②The rates of serum P, Ca and PTH examinations improved and increased constantly (c2=65.994, 80.834 and 182.306 respectively, P< 0.001). ③The compliance rates of serum P and Ca increased (c2=32.511 and 10.215 respectively, P<0.001 and =0.017 respectively), but the compliance rate of PTH remained unchanged (c2=0.764, P=0.858). Conclusion Based on the data feedback from this platform and continuous quality improvement, serum P level effectively reduced and serum P examination and compliance rates increased.
