Objectives

Narrative objectives1

The aim of this study is to prospectively and quantitatively evaluate the effects of three pre-discharge education methods - traditional face-to-face instruction, conventional video-based education, and AI avatar-based video education - on nursing workflow efficiency, patient understanding, and patient satisfaction. In a subset of participants, electroencephalographic measurements will be conducted using an affective analyzer to objectively assess the acceptability of the AI avatar-based video.

Developmental phase



Assessment

Primary outcomes

- Time required for healthcare providers' explanations (minutes)
- Number of explanations provided by healthcare providers (count)
- Patient understanding at the end of the first educational session
(objective assessment by healthcare providers using a five-item Likert scale, and subjective assessment using a comprehension test)

Key secondary outcomes

- Time required until the start of the intervention
- Patient satisfaction (questionnaire adapted from the CSQ-8)
- Need for additional explanations (presence/absence and content)
- Patient understanding at the first post-discharge outpatient visit
(objective assessment by healthcare providers using a five-item Likert scale, and subjective assessment using a comprehension test)
- Electroencephalographic measurements using an affective analyzer (affective values)
- Nurses' perceived workload (three-item short version of the NASA-TLX)
