The Effectiveness Of Teach-back Communication In Health Education For People With Heart Failure: A RCT Study

Objectives:To investigate the effectiveness of teach-back communication in health education for people with heart failure.In order to explore the effective method of health education for patients with heart failure.It could be provided the theory evidence that carrying out health education of patients with chronic diseases in clinical.Methods:This research is a experimental study,heart failure patients who were hospitalized in cardiology department of a Class III Grade I hospital were included in this study.They were randomly divided into experimental group and control group using the method of minimum imbalance index.While in hospital,the experimental group was given teach-back method for health education.However,the control group was given routine nursing care for health education.On admission?T?,the day before discharge?T₀?,one month after discharge?T₁?,three months after discharge?T₃?,using Atlanta Heart Failure Knowledge Test-V2?AHFKT-V2?and The Self-Care of Heart Failure Index?SCHFI?to investigate the level of heart failure knowledge and self-care.Rehospitalization were collected after discharge 3 months by making records and the phone call following up.In the end,the collected information and study data were analysed using SPSS 21.0.Results:In the experimental group,three people were dropped out,one people was died and four people were unabled to contact during the study.In the control group,two people were dropped out,three people were unabled to contact and four people had not been completed the experiment during the study.104 subjects finished the whole data collection,53 patients in the experimental group and 51 patients in the control group.The statistical results are as follows:1.Heart failure knowledge:The scores of experimental group on the total score of AHFKT-V2 at T,T₀,T₁ and T₃ were 13.75±1.31;22.21±1.65;21.94±1.49;20.87±1.48.The scores of control group on the total score of AHFKT-V2 at T,T₀,T₁ and T₃were 13.58±1.26;15.24±1.32;18.43±0.90;14.00±1.18.The scores of two groups on the total score of AHFKT-V2 at T was not statistically significant?P>0.05?.The scores of experimental group on the total score of AHFKT-V2 at T₀,T₁ and T₃ were higher than at T,the differences were statistically significant?P<0.01;P<0.01;P<0.01?.The scores of control group on the total score of AHFKT-V2 at T₀and T₁were higher than at T,the differences were statistically significant?P<0.01;P<0.01?.The scores of control group on the total score of AHFKT-V2 at T₃ were higher than at T,however,there was not statistically significant?P>0.05?.The scores of experimental group on the total score of AHFKT-V2 were higher than control group at T₀,T₁ and T₃,the differences were statistically significant?P<0.01;P<0.01;P<0.01?.2.Self-care:The scores of experimental group on the total score of SCHFI at T,T₀,T₁and T₃ were 78.32±9.67;148.41±12.27;190.69±8.07;213.36±94.25.The scores of control group on the total score of SCHFI at T,T₀,T₁ and T₃ were78.23±10.75;125.28±78.72;139.63±8.83;82.98±13.52.The scores of two groups on the total score of SCHFI at T was not statistically significant?P>0.05?.The scores of experimental group on the total score of SCHFI at T₀,T₁ and T₃ were higher than at T,the differences were statistically significant?P<0.01;P<0.01;P<0.01?.The scores of control group on the total score of SCHFI at T₀ and T₁were higher than at T,the differences were statistically significant?P<0.01;P<0.01?.The scores of control group on the total score of SCHFI at T₃ were higher than at T,however,there was not statistically significant?P>0.05?.The scores of experimental group on the total score of SCHFI were higher than control group at T₀,T₁ and T₃,the differences were statistically significant?P<0.01;P<0.01;P<0.01?.3.Cardiac readmissionsCardiac readmissions documented at 3 months after recruitment.Patients in experimental group yielded significantly less re-hospitalization than control group during the follow-up?0.34±0.55 vs.0.49±0.64,P>0.05?.Conclusion:The teach-back method was shown to improve the level of disease related knowledge and self-care of patients with heart failure,strengthen the patient's confidence to overcome the disease.It could be used to promote nursing work as a routine method.There was a lack of evidence on the effect of the teach-back method on reducing readmission times.
