171 Programme Theory to Guide the Adoption of Assisted Decision Making with Older People in Acute Healthcare: Realist Evaluation

Background In Ireland, the Assisted Decision-Making (ADM) (Capacity) Act and emerging Codes of Practice provide a legal framework for Healthcare Professionals (HCPs) to enable ADM for patients with impaired capacity. ADM ensures that a person’s will and preference is at the centre of all decisions related to their care. This study conducted a realist evaluation and developed a Programme Theory (PT) to highlight how ADM for older people can be operationalised within an Acute Care (AC) context. Methods Key informants with interest in ADM informed this evaluation. Interviews were conducted in two Acute Care (AC) sites with multidisciplinary HCPs working within older person services (n=20). Interviews with informants that recently received care within an AC setting involved older people (n=3) people with dementia (n=4) and family carers (n=5). Ethnographic observations from AC multidisciplinary team meetings also informed the review. The framework that guided the qualitative analysis was from a PT informed by literature on ADM implementation in healthcare (O'Donnell, Ní Shé, Davies et al.2018). Results The refined PT is supported by credible evidence that is informed by authentic experiences of decision making support in the AC setting. Validation groups (n=4) with the key informants verified the PT. Three mechanisms were identified as a positive climate and receptive environment for the adoption of formal ADM. These are: AC settings that adopt inter-professional accountability and shared responsibility for patient care that is guided by a clear policy process. Acute care and practice that is informed by a shared commitment to person-centred care and shared decision making. HCPs that operate within an AC setting where organisational learning informs practice through inter-professional training, mentorship and peer support. Conclusion Involving stakeholders in PT development enhances the utility, feasibility and applicability of the results. This PT provides a framework for those planning ADM implementation within the AC settings.
