Objective To explore the best mode of diabetic dietary education in the nursing specialist outpatient service,which is suit for China's national situation.Methods A total of 100 diabetic patients consulting diabetes diet in the nursing specialist outpatient service were divided into observation group and control group with 50 cases each by random digits table method.The routine sermonic education mode was used in control group,while the error-correction education mode was used in observation group.The question-real-time evaluation was performed at the end of the education and a follow-up evaluation after 6 months of intervention was evaluated.Results Grasp of the knowledge of diabetes diet in observation group immediately after education and 6 months after education were better than those in control group,t=3.07,3.06,P＜0.01.In the follow-up evaluation after 6 months of intervention,fasting blood glucose and glycosylated hemoglobin were (6.84±0.79) mmol/L,(6.83±0.36) ％ in observation group and (7.56±0.93) mmol/L,(7.67±0.87) ％ in control group.The indices in observation group were significantly better than those in control group,t=-4.17,-6.32,P＜0.01.Conclusions Using the error-correction education mode can correct the false dietary behavior of patients and improve the effect of the diabetic dietary education more effectively.
