%X <B>BACKGROUND: </B>In hemodialysis (HD) patients, anemia is greatly improved due to regular weekly use of iron and erythropoietin (EPO), but a large number of patients still show persistent anemia. We do a survey to elucidate the influencing factors that contribute to the failure of hemoglobin (Hb) to meet the standard and provide epidemiological data reference for promoting the recognition of renal anemia and improving the treatment effect of renal anemia.<BR><B>METHODS: </B>The clinical data of End-Stage Renal Disease (ESRD) HD patients in 22 tertiary hospital HD centers in Liaoning Province from September 2021 to June 2022 were collected by convenient sampling. According to the 2012 Kidney Disease: Improving Global Outcomes (KDIGO) anemia diagnostic criteria. The standard of Hb compliance: Hb ≥110 g/L is considered as Hb compliant, and Hb <110 g/L as Hb non-compliant. The factors influencing Hb up-to-standard in ESRD HD patients and their correlations were analyzed by comparison between the two groups.<BR><B>RESULTS: </B>The results of this study showed that among the 1,652 ESRD patients investigated in Liaoning Province, the prevalence rate of anemia was 89.29% (1,475/1,652), and the Hb compliance rate was 46.25% (764/1,652). The Hb compliance rate in maintenance hemodialysis (MHD) patients with different primary diseases was statistically significant (P<0.05). Compared with the Hb non-standard group, the gender, dialysis access, HD frequency, concurrent infection, primary disease of ESRD patients, red blood cell (RBC) count, hematocrit (HCT), mean RBC Hb concentration, mean RBC Hb content, platelet (PLT), albumin (ALB), total protein (TP), serum creatinine (Cr), serum calcium (Ca), serum potassium (K), ferritin (Fer), serum iron (SI), and transferrin (TRE) saturation were significantly different between both groups (P<0.05). Adrenaline was an independent risk factor affecting Hb failure in ESRD patients (OR =1.001, 95% CI: 1.000-1.002); dialysis frequency (OR =0.726, 95% CI: 0.601-0.878), ALB (OR =0.959, 95% CI: 0.929-0.990), TP (OR =0.982, 95% CI: 0.968-0.996), serum Cr (OR =0.959, 95% CI: 0.929-0.999), and SI (OR =0.961, 95% CI: 0.940-0.982) were protective factors affecting Hb failure in ESRD patients (P<0.05). Pearson correlation analysis showed that ALB, TP, serum Cr, serum Ca, serum K, SI, and TRE saturation were positively correlated with Hb (P<0.05).<BR><B>CONCLUSIONS: </B>The anemia rate of ESRD patients treated with MHD in Liaoning Province is high. Based on the results, increasing the frequency of dialysis can improve anemia. Parathyroid hormone levels need to be controlled.
