P1539THE INFLUENCE OF DIFFERENT HEMODIALYSIS FREQUENCY ON MHD PATIENTS WAS ANALYZED BASED ON THE DATA OF THREE CONSECUTIVE YEARS

Abstract

Abstract Background and Aims By analyzing the follow-up data of patients on maintenance hemodialysis (MHD) in the department of blood purification of the first affiliated hospital of Xi'an Jiaotong university from 2016 to 2018, the effects of different dialysis frequency on patients were compared and the continuous improvement of clinical quality was promoted. Method The general data of MHD patients in our center from 2016 to 2018 and annual laboratory monitoring indicators [including hemoglobin (HGB), calcium (Ca), phosphorus (P), parathyroid hormone (iPTH), serum albumin (ALB)] and their control rates were analyzed, and the differences in the above indicators of patients with hemodialysis frequency (2-times weekly, 5-times in two weeks and 3-times weekly) were compared. Results The proportion of patients older than 60 years old and the proportion of autologous arteriovenous fistula (AVF) increased year by year, while the use of the cuffed-tunneled catheter (TCCs) decreased. All indicators except iPTH have increased their control rates. Among the different dialysis frequencies: the average value of HGB and Ca was the highest at 3 times/week, and the control rate of P was not much different among the three groups. ALB was significantly lower in patients with 2 times/week than in other frequency groups (P<0.05). The average age of 3 times / week patients was significantly lower than 2 times / week and 5 times / 2 weeks (P <0.05). Conclusion In northwest China, the hemodialysis frequency to twice per week for most. The results of this study suggest that compared with the higher frequency, the major differences in the control rates are in albumin hemoglobin and serum calcium.
