A Chartered Health Psychologist was engaged by the Trinity Centre for Ageing and Intellectual Disability, Trinity College Dublin, to consult for a new National Intellectual Disability Memory Service in Ireland (NIDMS). One of the main strands of the consultancy project was to develop service delivery indicators for NIDMS. This involved designing a process to promote multiple levels of stakeholder enquiry for measuring quality in health care delivery (Donabedian, The quality of care: How can it be assessed? Journal of the American Medical Association, 260(12), 1743–1748, 1988; An introduction to quality assurance in health care. Oxford University Press, 2002). The psychologist worked within a multidisciplinary academic team on this project. Respectful, inclusive and empowering relationships were emphasised with all stakeholders, including the ultimate clients, people ageing with an intellectual disability. The process involved making reasonable adjustments to material to ensure meaningful feedback from these stakeholders. The consultative nature of the development of these service delivery indicators is promoted as best practice as it actively involves people with intellectual disability in the development of Irish health service delivery. This case study will focus on the building relationships aspect of the consultancy process, including adapting creatively to the restrictions imposed by Covid-19. The consultancy process maximised participation and minimised inequality of a potentially marginalised stakeholder group, thereby adhering to the core values of the National Intellectual Disability Memory Service.
