Abstract
Objective To survey the nutritional status of maintenance hemodialysis (MHD) patients and explore the role of oral nutritional supplement (ONS) in improving nutritional status among MHD patients. Methods From January 2016 to December 2017, one hundred and sixty-two MHD patients were selected randomly from hemodialysis centre of No. 2 peoples’ Hospital and assessed malnutrition incidence by objective score of nutrition on dialysis (OSND). Patients with malnutrition were divided into control group and ONS group randomly, patients in control group were conducted with traditional nutritional education, while patients in ONS group were conducted with ONS as a substitution of diet on the basis of control group. Finally, nutrition-related indexes were observed after 6 months. Results The malnutrition incidence of MHD patients was 66.7% (108/162) screening by OSND, the malnutrition incidence of patients over 60 years old was 82.8% (72/87), significantly higher than below 60 years old, 49.3%(37/75)(P 0.05). There was no significant difference of OSND, GNRI and MIS scores between control group and ONS group before intervention [OSND:(24.1±1.9) vs. (25.3±1.7), t=3.46, P<0.01; GRNI:(90.4±5.4) vs. (92.4±4.5), t=2.09, P=0.04; MIS:(9.2±3.2) vs. (10.9±3.3), t=2.72, P=0.01], while opposite after intervention (P<0.05). Subjective feeling score of patients in ONS group was significantly higher than control group after intervention [(10.7±3.5)vs(8.9±4.0), t=2.49, P=0.01]. The extra cost in control group and ONS group was (688.8±254.6) RMB and (749.2±44.9) RMB respectively with no significance (t=1.72, P=0.09). Conclusion The malnutrition incidence is high among MHD patients, traditional nutrition education takes poor patients compliance, while ONS could improve patients′ compliance and nutritional status because of scientific formula and good taste, which provide another diet selection for MHD patients. Key words: Malnutrition; Maintenance hemodialysis; Oral nutritional supplement; Objective score of nutrition on dialysis
