Abstract: 【Abstract】Objective To investigate the hemodialysis quality of elderly patients with end- stage renal disease (ESRD) and the relevant factors. Methods We included patients who started hemodialysis after 60 years of age at the Lanzhou University Second Hospital's Hemodialysis Center from July 2018 to February 2020. A total of 76 patients with complete data and their pre-dialysis and post-dialysis clinical data were collected. Results Elderly ESRD patients with comorbidities can reach as high as 50%, with the average estimated glomerular filtration rate (eGFR) level of (5.71±3.23)ml/(min·1.73m2) when starting hemodialysis treatment.
After treatment, the control rates of hemoglobin(Hb) (χ2=6.930, P=0.014), serum calcium (Ca) (χ2= 8.528，P=0.006), serum phosphate (P) (χ2=7.617, P=0.009), serum albumin (Alb) (χ2=14.729, P<0.001) were increased, and the rate of high intact parathyroid hormone (iPTH) is lower (χ2=6.233，P=0.019). According to the level of Hb, Ca, P, Alb, patients were divided into the standard group and the non-standard group. There was no significant difference in the eGFR level o (Z were -1.841, -1.128, -0.153, -1.629, -0.402, P values were 0.066, 0.259, 0.878, 0.103, 0.687, respectively), gender (χ2 were 1.690, 0.472, 0.471, 0.091, 0.169, P values were 0.194, 0.492, 0.493, 0.763, 0.681, respectively), course (t/Z were -0.944, -1.868, 1.036, -0.223, -1.047, P values were 0.345, 0.062, 0.306, 0.823, 0.295, respectively), vascular access (χ2 were 0.056, 0.153, 0.091, 2.487, 0.329, P values were 0.812, 0.696, 0.763, 0.115, 0.566, respectively), dialysis vintage (Z were -0.040, -1.798, -0.456, -0.008, -0.914, P values were 0.966, 0.072, 0.648, 0.994, 0.361) and hemodialysis methods (χ2 were 1.749, 0.220, 0.248, 1.513, 0.003, P values were 0.186, 0.639, 0.619, 0.219, 0.958, respectively) between two groups. Conclusion By strengthening late-stage individualized treatment and active and effective management of comorbidities, and improving the standard rate of clinical indicators, the timing of HD in elderly ESRD patients can be appropriately delayed.
