Aims and objectivesTo explore the contribution of clinical nurse specialists in intellectual disability nursing in Ireland.BackgroundWhile clinical nurse specialists exist since the 1940s, they have only been a reality in Ireland since 2001. While the role of clinical nurse specialist has developed over the years, it still however is often seen as a complex multifaceted role that causes confusion, frustration and controversy.DesignA exploratory qualitative approach using focus groups with Irish intellectual disability clinical nurse specialists (n=31).MethodsFive focus group interviews were conducted to gather qualitative data to gain insight into the attitudes, perceptions and opinions of the participants. Data were audio-recorded, transcribed and analysed using Burnard's (Vital Notes for Nurses: Research for Evidence-Based Practice in Healthcare, 2011, Blackwell Publishing, Oxford) framework. Ethical approval was gained from the researcher's university and access granted by the national council for the professional development of nursing/midwifery in Ireland.ResultsThe study highlights that intellectual disability clinical nurse specialists contribute to and support care delivery across a range of areas including client-focused and family-centred care, staff support, organisation support, community support and supporting other agencies.ConclusionsOverall, the study shows the importance of intellectual disability clinical nurse specialists and their contribution across a range of services, care environments and the support they offer to clients/families/staff/multidisciplinary team members and outside agencies.Relevance to clinical practiceIreland is in a unique position to develop knowledge regarding specialist care for people with intellectual disability that can be shared and adapted by other healthcare professionals in other countries that do not have specialised intellectual disability nurses.
