Key result
Teach-back method linked to ~9% greater knowledge mastery and lower anxiety after aortic dissection.
Why the study?
Aortic dissection requires comprehensive postoperative management, and the teach-back method may enhance comprehension, adherence to self-management, and reduce negative emotions.
Does the teach-back method improve health knowledge acquisition, self-management behaviors, and negative emotions in postoperative aortic dissection patients?
Cohort (n=210)
No
Does the teach-back method improve health knowledge acquisition, self-management behaviors, and negative emotions in postoperative aortic dissection patients?
The teach-back method significantly enhances health knowledge acquisition and reduces anxiety in postoperative aortic dissection patients compared to routine nursing care.

Teach-back education was associated with better knowledge mastery and lower anxiety post-AD; hypothesis-generating and requires RCTs before practice change.
Background Aortic dissection (AD) was a severe cardiovascular condition requiring comprehensive postoperative management. The teach-back method, a patient-centered educational strategy, may enhance patient comprehension and adherence to self-management practices post-surgery, potentially reducing negative emotions and improving outcomes. This study aimed to evaluate the impact of the teach-back method on self-management behaviors and negative emotions in postoperative AD patients at a tertiary hospital in China. Methods This retrospective cohort study was conducted at The First Affiliated Hospital of Nanchang University, China. It analyzed 210 postoperative AD patients from March 2021 to March 2023, divided evenly into a routine nursing group and a teach-back method group. Various assessments, including the Health Education Knowledge Acquisition Survey, Visual Analog Scale (VAS), Hamilton Anxiety (HAMA) and Depression (HAMD) Scales, Self Care Level Scale (ESCA), and WHO Quality of Life Inventory (WHOQOL-BREF), were performed pre- and post-intervention. Between-group comparisons were performed using independent t -tests or chi-square tests, with a significance level of P < 0.05. Results Patients in the teach-back group showed higher mastery of health education knowledge (96.19% vs. 88.57%; χ 2 = 4.33, P = 0.037) and significant reduction in anxiety levels [HAMA: 11.85 ± 4.00 [11.08, 12.62] vs. 13.15 ± 4.92 [12.20, 14.10]; t = 2.097, P = 0.037]. Self-management scores improved significantly in knowledge level and self-protective skills, with mean scores higher in the teach-back group ( P < 0.05). However, no significant differences were observed in pain scores or postoperative complications between the groups. Conclusion The teach-back method significantly enhances knowledge acquisition and anxiety reduction in postoperative AD patients, showing potential as a beneficial adjunct to routine nursing care.

Zeng et al. (2026) conducted a cohort in postoperative aortic dissection (n=210). Teach-back method vs. Routine nursing care was evaluated on Mastery of health education knowledge (p=0.037). The teach-back method enhanced the mastery of health education knowledge and reduced anxiety levels compared to routine nursing care in postoperative aortic dissection patients.
