Does a voice-guided tap-and-talk educational tool improve coronary heart disease knowledge and self-management behaviors in older adults following percutaneous coronary intervention?

Key Points

To develop a voice-guided tap-and-talk educational tool and evaluate its efficacy in improving disease-specific knowledge and self-management behaviors among older adults following percutaneous coronary intervention (PCI).
Assigned participants to receive health education via an interactive voice-guided tap-and-talk tool (n=49) or conventional printed manuals (n=47), assessing outcomes at baseline, 1 month, 3 months, and 6 months post-discharge.
Coronary heart disease knowledge scores were significantly higher in the intervention group at 1 month (14.02 ± 0.82 vs 13.30 ± 0.83), 3 months (13.79 ± 0.75 vs 13.13 ± 0.90), and 6 months (13.70 ± 0.66 vs 13.06 ± 0.89; group × time interaction F = 9.026, P < 0.001).
Total self-management behavior scores were consistently superior in the intervention group at 1 month (89.06 ± 10.64 vs 82.06 ± 6.65), 3 months (89.21 ± 7.51 vs 81.21 ± 6.62), and 6 months (89.15 ± 7.62 vs 81.06 ± 6.73; main effect of group F = 195.188, P < 0.001; all follow-up comparisons P < 0.01).
Participants reported high acceptability of the interactive tool (mean score 96.04 ± 2.61), while 3 adverse cerebrovascular events (cerebral infarctions) occurred across the study cohort over 6 months.

Intervention

Voice-guided tap-and-talk educational tool (commercial interactive pen with customized audio-coded manual, poster, and pill box) plus weekly text message reminders, delivered from admission to 6 months post-discharge.

Main Result

p-value: p=<0.001

A voice-guided tap-and-talk educational tool significantly improved disease-related knowledge and self-management behaviors in older adults recovering from PCI compared to standard printed materials.

Limitations

Patients and health education nurses were not blinded

Implication

Supports incorporating voice-guided tools into post-PCI education for older adults; extends RCT evidence for tailored digital self-management interventions.

Abstract

Objective This study aimed to develop a voice-guided, tap-and-talk educational tool and assess its effectiveness in improving disease-related knowledge and self-management behaviors among older adults following percutaneous coronary intervention (PCI). Methods A voice-guided tap-and-talk educational tool was designed to address the specific needs of older adults post-PCI. A cluster randomized controlled trial was conducted in cardiovascular wards. The control group received conventional health education using printed manuals, whereas the intervention group received education via the tap-and-talk interactive tool. Outcomes included the level of knowledge regarding coronary heart disease and engagement in self-management behaviors. Chi-squared test and independent-sample t-test, chi-square test and paired t-test, and univariate repeated-measures analysis of variance (ANOVA) were conducted accordingly. Results A total of 96 patients completed the study, including 49 in the experimental group and 47 in the control group.No statistically significant differences were observed in baseline characteristics between the groups ( p > 0.05). A significant group × time interaction effect was detected for coronary heart disease (CHD)-related knowledge (F = 9.026, P < 0.001). At 1 month, 3 months, and 6 months post-intervention, the intervention group demonstrated significantly higher self-management behavior scores than the control group (F = 11.607, P < 0.001). Additionally, CHD-related knowledge scores showed a mild downward trend over time in both groups (F = 124.067, P < 0.001). Consistent with the interaction effect mentioned above, the intervention group achieved significantly higher CHD-related knowledge scores than the control group at all three follow-up time points (1 month, 3 months, and 6 months post-intervention) (F = 195.188, P < 0.001). Scores in the intervention group remained consistently higher across all domains. The tool received high acceptance ratings from participants (mean score 96.04 ± 2.61). Conclusion The tap-and-talk voice-guided educational tool was effective in enhancing knowledge and promoting self-management behaviors among older adults following PCI. The tool demonstrated a high level of user acceptability within the target population.
