Abstract
Background
EDDIE + was a stepped wedge cluster randomised controlled trial with an embedded process evaluation in 11 residential aged care (RAC) homes in Queensland, Australia. The intervention aimed to upskill RAC staff to identify and manage deterioration to reduce unnecessary hospital transfer through education, decision support tools, diagnostic equipment and local facilitation. Main trial results indicated 46% of hospital admissions were due to falls and no significant improvements to outcome measures including hospital bed days were achieved. These findings were examined through a process evaluation.
Methods
A mixed methods approach guided by the i-PARIHS framework was used to assess fidelity, acceptability, mechanisms of impact and feasibility of implementation, including barriers and enablers. Semi-structured interviews, self-efficacy surveys, and project tracking documents were used. Qualitative data were coded to the i-PARIHS framework and quantitative data were analysed using linear mixed modelling.
Results
Fidelity varied considerably due to workforce shortages including vacancy in the local clinical facilitator role, high workload, COVID-19, and other contextual factors. Differences in job and team-related staff self-efficacy before and after the introduction of EDDIE + were not statistically significant. However, inductive thematic analysis of the questionnaires indicated that staff felt their knowledge, skills, confidence and communication had increased.
Conclusions
The process evaluation indicates high acceptability of the EDDIE + intervention. However, fidelity and intended mechanisms of impact were mixed despite substantial pre-planning prior to implementation. For future studies, specific barriers in the RAC setting such as staffing and turnover may be unable to be adequately addressed without systemic change.
Trial registration
The trial is prospectively registered with the Australia New Zealand Clinical Trial Registry (ACTRN12620000507987, registered 23/04/2020).
