| Objective: To apply the mobile medical application(APP)in nutrition education of peritoneal dialysis patients,explore its applicability in nutrition education of peritoneal dialysis patients,and to evaluate its impact on the nutritional status of peritoneal dialysis patients.Methods: A randomized controlled trial was used to enroll all peritoneal dialysis patients who were treated and followed up at a peritoneal dialysis center Class A General Hospital in Sichuan Province from March 2022 to June 2022 and met the inclusion criteria.Registered patients were randomly divided into two groups: the control group received nutrition education in the traditional way,and the experimental group received nutrition education based on the mobile medical APP.All patients received nutrition education for 6 months,and patients in both groups were followed up and data collected 3 months and 6 months after the intervention.SPSS23.0 software was used to perform descriptive statistical analysis,Cochran’s q test,Scheirer Ray-Hare test,and ANOVA for repeated measures of research data.To compare the effect of different nutrition education methods on nutritional status,self-management capacity,nutrition-related laboratory parameters,and anthropometric indexes of peritoneal dialysis patients.Results:(1)A total of 119 patients were enrolled in this study,including 60 in the experimental group and 59 in the control group.At enrollment,the baseline data of the two groups were comparable(p > 0.05).After the intervention,the utilization rate of APP in the experimental group was 100%,78.0% of the patients thought that APP was easy to use,and 84.7% of the patients were willing to continue to use APP for nutrition education.(2)The incidence of protein-energy wasting in the experimental group decreased sequentially before intervention,three months after intervention and six months after intervention(51.7% vs 30.0% vs 13.3%,p < 0.05).After six months of intervention,the incidence of protein-energy wasting in the experimental group was significantly lower than that in the control group(13.3% vs 32.3%,p < 0.05).The time effect,group effect and interaction effect of the modified quantitative subjective global assessment score of the two groups were significant(p < 0.05).After the intervention,the modified quantitative subjective global assessment score of the experimental group decreased in turn [12.00(10.00,14.00)vs 11.00(9.00,12.00)vs 9.00(8.00,11.00),p < 0.05].And the three-month [11.00(9.00,12.00)vs 12.00(9.00,15.00)] and six-month [9.00(8.00,11.00)vs 11.00(9.00,14.00)] of the intervention group were lower than those of the control group at the same time point(p < 0.05).The time effects of AST,TP,Fe and TS in the two groups were significant(p < 0.05),the time effect and group effect of Hb were significant(p < 0.05),and the time effect and interaction effect of Alb were significant(p < 0.05).The time effect of body mass index in the two groups was significant(p < 0.05).(3)The group effect of self-management ability scores of the two groups was significant(p < 0.05).After three months of intervention,the self-management ability score of the experimental group was higher than that of the control group(57.10±10.44 vs 51.94±13.31,p < 0.05).In the two groups of patients,only the group effect was significant in the three dimensions of peritoneal dialysis standardized operation ability,peritoneal dialysis effect evaluation and monitoring and drug management(p < 0.05),and the time effect and group effect were significant in the dimension of diet management ability(p < 0.05).Conclusions: Mhealth APP-based nutrition education is feasible in peritoneal dialysis patients,and patients have a good experience of using the APP.It can improve the nutritional status of peritoneal dialysis patients and enhance their self-management ability to a certain extent. |
