Abstract

Objective: To evaluate the effectiveness of a blended intervention model comprising a short instructional video and direct nursing consultation on patients’ knowledge of post-cataract surgery eye care at Ho Chi Minh City Eye Hospital. Methods: A pre–post intervention study without a control group was conducted on 160 patients from May to September 2025. The intervention included a 5-minute video and a 15-minute nursing consultation. Knowledge was assessed using a 20-item true/false questionnaire at two time points: before and one week after the intervention. Data were analyzed using SPSS 26.0: McNemar, Wilcoxon, and logistic regression (p < 0.05). Results: The average knowledge score increased significantly from 10.64 ± 2.42 to 18.75 ± 1.10 points (p < 0.001). The proportion of patients achieving a "good" knowledge level (score ≥ 16) rose from 4.4% to 99.4%. Correct knowledge improved markedly across all topics: medication use (58.8% → 95.6%), eye hygiene (56.9% → 99.4%), post-surgery activities (57.5% → 96.9%), and lifestyle after surgery (55.6% → 98.8%). Factors associated with incorrect knowledge post-intervention included: age ≥ 70 (OR = 2.48; p = 0.049), male gender (p < 0.001), and rural residence (p = 0.043). Conclusion: Educational videos combined with direct nursing counseling significantly improved patients’ post-operative knowledge, especially in elderly patients. This model should be expanded, with content adjustments for high-risk groups.
