Abstract  Objective：To explore the influencing factors of fear of progression in middle⁃aged and elderly maintenance hemodialysis patients and their spouses by using random forest algorithm.Methods：Using convenient sampling method， 239 middle-aged and elderly maintenance hemodialysis patients and their spouses who were treated in hemodialysis centers of tertiary grade A hospitals in Luzhou were investigated， and the importance of influencing factors was ranked by random forest model.Results：The total score of fear of progression in middle⁃aged and elderly FoP patients was （38.48±8.49）， and the total score of fear of progression in spouse was （38.05±8.21）. Random forest importance ranking shows that dialysis age， positive coping style and age of patients were the top three important factors affecting the fear of progression in middle⁃aged and elderly patients. Spouse's positive coping style， spouse's illness perception and spouse's social support are the top three important factors affecting the progress of spouse's fear of progression in middle⁃aged and elderly maintenance hemodialysis patients.Conclusion：Middle⁃aged and elderly maintenance hemodialysis patients and their spouses generally have serious fear of progression. Clinical medical staff should pay attention to it and formulate personalized intervention measures for patients and their spouses with different characteristics.
