This study is an experimental study. The main caregivers of pressure injury patients in the plastics surgery ward and general medicine ward of the hospital in Taipei City who are over 20 years old, have good communication skills in Chinese and Taiwanese or who can read Chinese are the research objects. During the study process, pre-tests will be given to the accepted subjects, which are the correctness evaluation scale of caregiver's pressure injury wound dressing change and caregiver self-efficacy scale, and then the accepted subjects will be divided into experimental group and control group. The experimental group will receive interventions of virtual reality and artificial intelligence wound detecting system, while the control group maintained the traditional pressure injury health education with oral introduction and health education leaflet. After the intervention measures are given, a post-test (same as the pre-test content) will be conducted within two days. Finally, analyze the effectiveness of the intervention of virtual reality pressure injury education video and artificial intelligence wound detecting system on caregivers of pressure injury improve wound care correctness and increase self-efficacy.

Pressure injury care is a great burden for caregivers from non-medical backgrounds. Due to low self-efficacy, caregivers often do not have enough confidence to perform correct wound dressing procedures, which leads to ineffective care of pressure wounds and causes the pressure injury patient's wound repeatedly inflamed and deteriorated. Therefore, the purpose of this study is to investigate the effectiveness of the intervention on the correctness of dressing change and self-efficacy of pressure injury caregivers through virtual reality of pressure injury education videos and artificial intelligence wound detecting system. This study is an experimental study. The main caregivers of pressure injury patients in the plastics surgery ward and general medicine ward of the hospital in Taipei City who are over 20 years old, have good communication skills in Chinese and Taiwanese or who can read Chinese are the research objects.

After the intervention measures are given, a post-test (same as the pre-test content) will be conducted within two days. Finally, analyze the effectiveness of the intervention of virtual reality pressure injury education video and artificial intelligence wound detecting system on caregivers of pressure injury improve wound care correctness and increase self-efficacy.
