The Wessex AHSN has put together a 18-minute video on how to screen for malnutrition (undernutrition) using the Malnutrition Universal Screening Tool (‘MUST’). This version is specifically for staff working in Dorset as part of the Pan Dorset Malnutrition Programme. This video has a particular focus on calculating the ‘MUST’ score with community-dwelling older adults. This video is suitable for use both as an individual viewer or to be used as part of a group training session (we have included opportunities to pause the video for group discussions). As this video builds on the content from our ‘OPEN undernutrition awareness training video’ (https://vimeo.com/281427544), we recommend you view this video first to provide the appropriate background and context around undernutrition in older people.
