Objective To explore the effect of mind mapping-based health education on the discharge readiness of patients undergoing laryngectomy.Methods From August 2022 to July 2023,convenience sampling was used to select patients who underwent first-time laryngectomy in the Otolaryngology and Head and Neck Surgery at Beijing Tongren Hospital as participants.The patients were divided into an observation group and a control group according to admission time,with 60 cases in each group.The control group received routine health education,while the observation group was treated with mind mapping-based health education.After the intervention,the discharge readiness and discharge guidance quality of two groups of patients were compared.Results A total of 120 questionnaires were distributed and 120 valid questionnaires were collected,with a valid response rate of 100.00%.After the intervention,the discharge readiness and discharge guidance quality scores of the observation group were higher than those of the control group,and the difference was statistically significant(P<0.01).Conclusions Mind mapping-based health education can improve the discharge guidance quality and discharge readiness for patients undergoing laryngectomy and provide a reference for medical and nursing staff.
