Abstract: Objective To explore the standard-reaching rate of hemoglobin after the treatment and its influencing factors in maintenance hemodialysis (MHD) complicated with anemia. Methods A total of 314 MHD patients with anemia were divided into standard- reaching group (n=106) and non- standard- reaching group (n=208) after the treatment. The factors relating to the standard-reaching rate were analyzed using univariate and multivariate logistic regression methods. Results The standard-reaching rate was only 33.8% in MHD patients with anemia (106/314) after the treatment. Multivariate logistic regression indicated that age of dialysis (OR=2.115, 95% CI 1.386～2.844, P=0.006), frequency of dialysis (OR=2.472, 95% CI 1.660～3.283, P=0.001), serum albumin (OR=1.872, 95% CI 1.076～2.668, P=0.002), iPTH (OR=1.846, 95% CI1.183～2.508, P=0.006) and serum iron (OR=3.504, 95% CI 2.385～4.623, P＜0.001) were the influencing factors for standard-reaching rate in MHD patients with anemia. Conclusion The standard reaching-rate of hemoglobin was low after the treatment for MHD patients with anemia. The independent factors relating to standard- reaching rate of hemoglobin included longer dialysis age, lower dialysis frequency, lower serum albumin
and iron, and higher iPTH. Intervention measures to improve these factors may be useful for the increase of standard-reaching rate of hemoglobin.
