Abstract: 【Abstract】Objective To explore the effect of continuous quality improvement (CQI) strategy on hemoglobin (Hb) level in maintenance hemodialysis (MHD) patients. Methods A total of 299 MHD patients treated in Hemodialysis Center of Peking University People's Hospital from Jan. 2006 to Dec. 2013 and with complete clinical data were enrolled in this study. The PDCA, a 4-step problem-solving frame work of CQI based on NKF-K/DOQI and KDIGO guidelines, was used for the management of Hb level in MHD patients. Average Hb level, proportion and frequency of patients with targeted Hb level were compared every year. Results In 2006, average Hb was 105.0±18.6 g/L, Hb level reached the target level was 37.5% in 96 MHD patients, and the frequency of Hb level reached the target level was 41.7% in 204 Hb measurements. After the performance of CQI strategy, average Hb increased to 111.1±10.3 g/L in 109 patients (P=0.000) in 2011, Hb level reached the target level was 61.8% in 152 MHD patients (P=0.000) in 2013, and the frequency of Hb level reached the target level was 59.9% in 1147 Hb measurements (P=0.000) in 2013. Conclusions The implementation of CQI strategy resulted in the increase of Hb level in MHD patients and was thus useful for the management of anemia complication in MHD patients.
