Description of the study population (n = 1569).

Background and objectives
Health education can help patients engage in evidence-based healthy behaviors, and the construction of smart hospitals can promote accurate video-based health education for patients. However, little is known about the clinical practice of personalized video-based health education for ischemic stroke patients in China. We investigated video-based health education viewing frequency and relevant impact factors among patients with ischemic stroke.
Methods
Data were collected from 1,569 ischemic stroke patients admitted to the Vascular Neurology Ward of a hospital in China between 01/08/2020 and 31/12/2022, to analyze their use of personalized video-based health education. The video-based integrated management system used in our hospital can facilitate keyword extraction, thus achieving accurate and personalized video-based health education and promotion. Data, including demographic and disease-related data, viewing frequency, total viewing amount and viewing frequency for each dimension, were extracted from the hospital’s video integrated management system and medical system. Univariate analysis and multiple linear regression helped identify factors associated with whether the patients viewed personalized video-based health education materials.
Results
A total of 1569 patients were included (age = 58.72 ± 13.50 years old; 1177 (75.0%) males). Diet rehabilitation education was the most frequently viewed personalized video-based health education dimension; the average viewing frequency was 2.30 ± 1.15 times/day during an average hospitalization of 12.55 ± 4.12 days. According to the multivariable analysis, factors associated with a reduced likelihood of viewing the personalized video-based health education materials (P < 0.05) included visual and hearing impairment, longer hospital stays, and speech impairment. In contrast, compared to self-paying patients, individuals who were covered by medical insurance or received free medical service were more likely to view the personalized video-based health education materials.
Conclusion
A personalized video-based health education program with a keyword extraction function can help achieve accurate and personalized video-based health education and promotion and effectively improve patients’ health-education participation rate.

研究背景与目的
健康教育可帮助患者践行基于循证医学的健康行为，智慧医院（smart hospitals）建设可推动面向患者的精准视频化健康教育（video-based health education）。然而，目前国内针对缺血性脑卒中（ischemic stroke）患者的个性化视频化健康教育（personalized video-based health education）临床实践现状仍鲜为人知。本研究旨在探讨缺血性脑卒中患者的视频化健康教育观看频次及其相关影响因素。
研究方法
本研究纳入2020年1月8日至2022年12月31日期间，中国某医院血管神经内科病房（Vascular Neurology Ward）收治的1569例缺血性脑卒中患者，以分析其个性化视频化健康教育的使用情况。本院所采用的视频化综合管理系统可支持关键词提取，从而实现精准且个性化的视频化健康教育与推广。研究从医院视频综合管理系统与医疗系统中提取了人口统计学资料、疾病相关数据、观看频次、总观看量及各维度观看频次等信息。采用单因素分析（univariate analysis）与多元线性回归（multiple linear regression）分析，筛选出与患者观看个性化视频化健康教育素材相关的影响因素。
研究结果
本研究共纳入1569例患者，患者平均年龄为58.72±13.50岁，其中男性1177例，占总人数的75.0%。饮食康复教育为患者最常观看的个性化视频化健康教育维度；患者平均住院时长为12.55±4.12天，日均观看频次为2.30±1.15次。多变量分析（multivariable analysis）结果显示，视听障碍、住院时长较长以及言语障碍与患者观看个性化视频化健康教育素材的概率呈显著负相关（P<0.05）。与之相反，与自费患者相比，医保参保患者及享受免费医疗服务的患者观看个性化视频化健康教育素材的概率显著更高。
研究结论
搭载关键词提取功能的个性化视频化健康教育方案，可助力实现精准且个性化的视频化健康教育与推广，并有效提升患者的健康教育参与率。
