BACKGROUND: Fetal alcohol spectrum disorder (FASD) is a highly prevalent neurodevelopmental disability caused by prenatal alcohol exposure (PAE). Healthcare professionals (HCP) are key in prevention, diagnosis, and supporting individuals with FASD. This study explored the FASD knowledge, attitudes, and practices among HCP in Aotearoa, New Zealand (NZ). METHODS: We conducted an online survey of HCP working in NZ. The survey measured knowledge of FASD, beliefs and attitudes about FASD, experiences and practices with FASD and future training. RESULTS: Of the 96 participants, more than 90% self-reported a good or very good understanding of FASD, and around half had a patient with FASD. However, less than half felt prepared to support someone with FASD. Participants identified lack of professional training, services, and funding as barriers to support individuals with FASD. CONCLUSION: We identified a need to provide training and promote awareness and recognition for HCP to support individuals with FASD.
