Interprofessional Education (IPE) is a necessary step in preparing a collaborative practice-ready health workforce that is better prepared to respond to local and global health needs. This study examined the status of IPE implementation in Asian nursing schools in the World Health Organization (WHO) Western Pacific Region (WPR). Descriptive online survey research design was utilized, supplemented by online interviews. Purposive sampling was done wherein nursing schools, colleges, and universities were invited to nominate a representative to serve as respondent in this study. Descriptive approach was used to analyze both quantitative and qualitative data. A total of 29 Asian nursing schools participated in the survey. Majority (82.76%) of them stated that they have an IPE program or a similar activity. Interviews with the respondents revealed that not all IPE opportunities were part of a formal IPE program, but were embedded in the different learning activities of nursing students. A clear program focus served as one of the facilitators of IPE implementation. Identified barriers included insufficient administrative support and lack of trained faculty to implement IPE and related activities. IPE is present in most Asian nursing schools in WPR. They may not exactly be called or recognized as IPE, but there is the existence of programs and activities that bring together health and non-health science students to learn from, about, and with each other to enable effective collaboration and improve health outcomes. It is recommended that massive formal training should be conducted so that educational institutions and their faculty will be equipped in developing more formal programs, facilitate activities, and monitor implementation and progress.
