Abstract: 【Abstract】Objective To analyze the control status of medical quality indexes in elderly maintenance hemodialysis (MHD) patients and its effect on prognosis of the patients. Methods A total of 64 MHD patients over 60 years old treated in our hospital in 2019 were enrolled in this study. Medical quality indexes evaluated every 3 months in 2019 were analyzed. They were followed up for one year. Cox proportional hazard model was used to assess the risk of death. Results In the 64 MHD patients, the medical quality indexes that met the control standards in the 4 evaluations in 2019 were hemoglobin (16 cases, 25.0%), serum albumin (30 cases,
46.9%), serum calcium (45 cases, 70.3%), serum phosphorus (20 cases, 31.3%), parathyroid hormone (29 cases, 45.3%) and Kt/V (26 cases, 40.6%). The increase of control rates of hemoglobin and parathyroid hormone could reduce the risk of death with the risk ratio of 0.05 (95% CI 0.00～0.74, P=0.029) and 0.03 (95% CI 0.00～0.69, P=0.029), respectively. Conclusion The control rates of medical quality indexes were low in elderly MHD patients. Patients with a higher control rates of hemoglobin and other medical quality indexes had a relatively lower risk of death in one year. Strict control of medical quality indexes has a great clinical
significance in elderly MHD patients.
