Multilingual Video Education for Hospitalized Patients With Myocardial Infarction (EDUCATE-MI): Single-Arm Implementation Study.

The multilingual educational video significantly improved patient knowledge of MI before hospital discharge.

• Average number of correct responses out of 10 was 5.4 (SD 2.7) at baseline and 7.2 (SD 2.5) postintervention.
• Mean difference was 1.9 (95% CI 1.6-2.2; P<.001).
• Effect size was moderate-to-large: Cohen drm for paired change = 0.72.
• 128 of 129 enrolled participants completed follow-up immediately postintervention (1 lost interest).
• Knowledge was measured by comparing mean number of correct responses before and after intervention using a 2-tailed paired t test.

The educational video demonstrated high acceptability among hospitalized MI patients.

• 83.6% (107/128) of participants found the video easy to understand.
• 74.2% (95/128) found the video engaging.
• 87.5% (112/128) found the video useful.
• Acceptability was assessed as one of two prespecified implementation outcomes from the Proctor implementation outcomes framework.

Fidelity of both the intervention and the implementation strategy was assessed as reasonably achieved.

• Core components of the intervention (animations and educational content conveyed through audio and subtitles) were delivered as intended.
• No technology issues prevented delivery of the intervention as intended.
• The intervention was delivered through video display from a weblink embedded in REDCap, using a tablet with internet connection.
• Fidelity was one of two prespecified implementation outcomes assessed using the Proctor implementation outcomes framework.

Participants provided feedback identifying areas for improvement in the educational video, particularly around content complexity and language style.

• Content analysis was performed on notes taken from participants' feedback.
• Feedback highlighted content complexity as an area for improvement.
• Participants expressed a preference for conversational language and dialects.
• These findings were used to inform potential improvements to the video.

The study enrolled 129 participants with a mean age of 59.4 years, predominantly preferring English, with Hindi as the most common non-English language.

• 129 participants were recruited from December 2023 to October 2024 in a tertiary hospital.
• Mean age was 59.4 years (SD 12.6 years).
• English was the preferred language for 96 participants (74.4%).
• Hindi was the predominant non-English preferred language (n=17, 13.2%).
• The video was available in English, Arabic, Hindi, and Mandarin (with Simplified Chinese subtitles) and was delivered via a tablet provided by the research assistant.
