Abstract:
Objective To explore the potential categories and influencing factors of cognitive function trajectories in elderly hemodialysis patients.Methods A convenience sampling method was used to select elderly patients undergoing hemodialysis in the blood purification center of a tertiary hospital in Beijing,China,from June 2022 to June 2024.A general information questionnaire,the Short Physical Performance Battery,the Patients Health Questionnaire-9,the Impact on Participation and Autonomy Questionnaire,the Hemodialysis Self-Management Instrument,and the Mini-Mental State Examination,were used to collect data at the time of enrollment.Cognitive function was evaluated at the time of enrollment and 6,12,18,and 24 months after enrollment,using latent category growth model to identify trajectory categories,and logistic regression,and decision tree models to analyze the influences on cognitive function trajectories.Results Finally,304 patients were included.A total of 2 trajectories of cognitive function in elderly hemodialysis patients were identified,namely,high-level stable group(63.2％)and low-level declining group(36.8％).Both logistic regression and decision model results showed that the type of dialyzer,body mass index,physical function,and depression status were the factors influencing potential categories of cognitive function for elderly hemodialysis patients.The areas under the receiver operating characteristic curves for logistic regression and decision tree models were 0.823[95％CI(0.775,0.870)]and 0.816[95％CI(0.765,0.867)],respectively.Conclusion There is heterogeneity in the cognitive function trajectories of elderly hemodialysis patients,and healthcare professionals can develop targeted interventions according to the influencing factors of the trajectory categories to improve their cognitive function.
