Objective To discuss the application value of video health education mode in patient's self-maintenance of totally implantable venous access port(TIVAP).Methods A total of 208 patients,who received implantation of TIVAP at the Second Affiliated Hospital of Naval Military Medical University of China From September 2021 to December 2022,were enrolled in this study.The patients were divided into control group(n=108)and observation group(n=100).Traditional health education was conducted for the patients of the control group,while on the basis of traditional health education an additional video health education based on visual communication theory was carried out for the patients of the observation group.Evaluation of self-care ability(ESCA)was used to evaluate the self-care ability before the intervention and 6 months after the implantation of TIVAP in the two groups.The complications,the incidence of adverse events,and the indwelling duration of the infusion port were compared between the two groups.Results Before intervention,the differences in each dimension score and total score of ESCA table between the two groups were not statistically significant(all P>0.05).After intervention,the each dimension score and total score of ESCA table in the observation group were significantly higher than those in the control group(all P<0.05).After intervention,both the total incidence of complications and the total incidence of adverse events in the observation group were remarkably lower than those in the control group(both P<0.05),besides,the indwelling duration of the infusion port in the observation group was obviously longer than that in the control group.Conclusion The use of video health education mode can significantly improve the self-care ability of patients carrying a TIVAP,reduce the incidence of complications and adverse events,and extend the effective duration of TIVAP.Therefore,it is an effective health education mode.
