Abstract:
Objective To investigate the current status of adherence to home ultrafiltration volume measurement in peri-toneal dialysis(PD)patients and explore its influencing factors,providing a basis for optimizing volume management strategies.Methods A cross-sectional study design was adopted.In March 2024,a questionnaire survey was conducted among 324 regular-ly followed-up patients at the Peritoneal Dialysis Center of the First Affiliated Hospital of Xi'an Jiaotong University.The question-naire covered demographic characteristics,ultrafiltration volume recording behaviors,measurement method awareness,and instru-ment preferences.Possible factors influencing adherence to ultrafiltration volume measurement were analyzed.Results The o-verall compliance rate for recording patients' ultrafiltration volume was 56.2％(182/324)％.The completion rate of measure-ment was better in the measuring cup group compared to the weighing method(57.3％vs 47.4％,P=0.034).However,Meas-urement compliance decreased with prolonged dialysis duration(P=0.021).78.39％of patients could identify emergency situa-tions of volume expansion(e.g.,sudden decrease in ultrafiltration volume accompanied by elevated blood pressure).However,patients with lower education levels(below high school)had poorer awareness of volume changes compared to those with higher education(81.4％vs 18.5％,x2=9.946,P=0.041).The recognition rate for volume depletion was significantly lower than that for volume expansion(x2=7.163,P=0.008).Multivariate logistic regression analysis showed that higher education level(OR=0.404,95％CI 0.228-0.717,P=0.002),family assistance in measurement(OR=0.361,95％CI 0.183-0.713,P=0.003),and strong belief that measurement helps doctors adjust prescriptions(OR=0.371,95％CI 0.187-0.736,P=0.005)were protective factors for compliance with ultrafiltration volume measurement in peritoneal dialysis patients.Longer dialysis dura-tion(OR=4.732,95％CI 2.315-9.674,P＜0.001)and perception of measurement as troublesome(OR=4.802,95％CI 2.787-8.272,P＜0.001)were independent risk factors for poor compliance with ultrafiltration measurement.Compared with pa-tients with low educational level,patients with high educational level had higher requirements for the ease of operation(38.6％vs 61.4％,x2=15.033,P＜0.001),cost performance(41.1％vs 58.9％,x2=13.335,P＜0.001),and durability(38.2％vs 61.8％,x2=4.558,P=0.033)of the new ultrafiltration measurement equipment.Conclusion ① Long dialysis duration,per-ceived measurement inconvenience,low education level,self-measurement,and insufficient trust in physicians are independent risk factors for poor adherence to home ultrafiltration volume measurement among PD patients.②The vast majority of patients can recognize emergency situations involving sudden volume overload,but their awareness and recognition of volume depletion require further improvement.③New measuring instruments,such as intelligent measuring cups,with easy-to-use operations can be pro-moted.When combined with remote monitoring technology,they help patients identify capacity insufficiency promptly and im-prove the rate of early intervention.
