Examining Quality, Use and Impact of Psychotropic (Use) in older adults with intellectual disabilities (EQUIP): study protocol

Widespread, and sometimes inappropriate use of psychotropics in adults with intellectual disability has been an international concern. These medicines have been used to treat mental health conditions, but also, controversially, some types of behaviours not necessarily associated with the diagnosis or in the absence of a relevant diagnosis. Results from the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA) study of older adults with intellectual disability in Ireland revealed that 60% were taking psychotropics in 2010. In the intervening decade changes in regulations, policy, and increased decongregation of people with intellectual disability have taken place likely influencing the use of psychotropics. The HSE National Clinical Programme for People with Disability (NCPDD) established in the 2020 has medicines optimisation as a key priority. Existing multi-wave data from the IDS-TILDA study and the HSE national prescribing database offers an opportunity to better understand psychotropic use and prescribing patterns. This is a novel collaboration on lived experience, research, practice and policy. The aim of this research is to examine the quality and trends of psychotropic use of older adults with intellectual disability over a ten-year period in Ireland to evaluate the effects of and to inform both practice and policy to optimise medicines use and health outcomes. Health and medication data from ten years (four waves) of the IDS-TILDA study and corresponding medicines data from the HSE-PCRS prescribing database are available. Descriptive and longitudinal analysis will examine association between long-term psychotropic use, changes in trends of use, and the impact of decongregation on medicines use. This research will inform the development of national guidance on medicines optimisation for older people with intellectual disability and has the potential to change prescribing practices and improve health and wellbeing for older people with intellectual disability.
