Objective To explore the latent class of the symptom characteristics in the patients with maintenance hemodialysis(MHD),and to analyze the factors affecting different latent class.Methods The convenience sampling method was adopted to select 380 cases of MHD in the Blood Purification Center of a class 3A hospital in Nanjing City from March to May 2022 as the respondents.The general data questionnaire,disease related data questionnaire and dialysis patient symptom assessment scale(DSI)were adopted to con-duct the questionnaire survey.The symptoms characteristics of the respondents conducted the latent class a-nalysis(LCA).Then the influencing factors of different latent categories were analyzed by the univariate anal-ysis and multivariate logistic regression.Results The symptom characteristics in the patients with MHD could be divided into 3 categories:symptom high incidence type(24.7％),sexual dysfunction type(31.3％)and symptom low incidence type(43.9％).Compared with the patients with symptom low incidence type,the patients with low age group and low income were more likely to be classified as the symptoms high incidence type.The patients with entering middle age(45-60 years old),having spouse,low income and short dialysis age were more likely to be classified as the sexual dysfunction type.Conclusion Medical staff should effective-ly identify the different symptoms characteristics in the same group of the patients,and give the personalized intervention management.

Objective:To understand the current status of fear of falling in patients receiving maintenance hemodialysis and analyze the influencing factors.Methods:The convenient sampling method was used to select maintenance hemodialysis patients admitted to BenQ Hospital Affiliated to Nanjing Medical University from August to October 2022 as the research objects. A survey was conducted on patients using the general information questionnaire, modified falls efficacy scale (MFES), fatigue, resistance, ambulation, illness, loss of weight (FRAIL), and Braden Mobility Subscale.Results:A total of 219 questionnaires were sent out, and 219 were effectively collected, with an effective recovery rate of 100.00%. Among 219 patients with maintenance hemodialysis, 96 had fear of falling, and the incidence of fear of falling was 43.84%. Binary logistic regression analysis showed that age, type of kidney disease, fall history, and score of FRAIL were the influencing factors of fear of falling in patients with maintenance hemodialysis ( P< 0.05) . Conclusions:The incidence of fear of falling in patients with maintenance hemodialysis is relatively high. Age, diabetic nephropathy, history of falls, and frailty are the risk factors for fear of falling in patients with maintenance hemodialysis. Medical staff can develop targeted intervention measures for maintenance hemodialysis patients based on risk factors to reduce their fear of falling.
