Protocol for an exploratory, longitudinal single case study of a novel palliative care rehabilitative service

Background: Early access to rehabilitation can improve quality of life for those with life-limiting illnesses and is highlighted as a core component of the Adult Palliative Care Services Model of Care for Ireland. Despite this, palliative rehabilitation remains under-utilised and under-developed. In 2020, the Sláintecare Integration Fund provided opportunity to pilot a novel rehabilitative palliative care service, "Palliat Rehab". This protocol proposes a case study, which aims to advance understanding of the form, content, and delivery of the pilot service. Methods: A prospective, longitudinal, mixed-methods, case study design will be used to describe the service and to explore the experiences of patients, informal carers and clinicians. Additionally, data collection instruments will be tested and the utility of outcome measures will be examined. Data will be collected from documentary, survey, and interview sources. Quantitative data will be analysed using descriptive statistics, including chi-square tests for categorical variables, Mann-Whitney U tests for ordinal data, and t-tests/ ANOVA for continuous data. Qualitative data will be analysed using thematic analysis. Conclusions: New pathways are required to advance service provision to ensure that patients receive the 'right care, in the right place, at the right time'. This protocol outlines a case study which will aim to develop current understanding of the implementation and delivery of a novel rehabilitative palliative care service in Ireland and will consider its potential contribution to the achievement of Sláintecare goals. Investigating the service within its environmental context will lead to a better understanding of 'how' and 'why' things happen. Findings will be used to inform efforts to further develop and tailor the intervention.
