Ageing and dementia affect many aspects of life, including intimate relationships, sex and sexual expression. Older people, including those living with dementia, can have sexual relationships and form new ones. Their sexual and physical health, quality of life, and psychological well-being can be improved by respecting their intimacy and sexuality expression preferences. However, due to ageism and stigma, healthcare professionals often ignore the sexual feelings and needs of those with dementia living in long-term care. Discussions with stakeholders and literature show limited attention paid to understanding the sexual preferences of people living with dementia in health and social care. In 2020, the Intimacy and Sexuality Expression Preference (ISEP) tool was developed for use in long-term care to gather information on intimate and sexual expression preferences of older people, including those living with dementia, to assist in care provision. The ISEP tool was trialled in a Queensland, Australia, nursing home with 14 older residents. This presentation will share insight into the use of the ISEP tool and how it informs the development of ‘ISEP: A Practical User Guide’. This guide provides information on how to (a) use the ISEP tool for assessment; (b) interpret and integrate findings into care (i.e., identify a potential course of action); and (c) evaluate outcomes. Illustrative examples will be included. It will inform how preferences for the expression of sexuality can be practically addressed to improve care practices and care outcomes (i.e., satisfaction and quality of life) for people with dementia.
