Implementation of advance care planning in the routine care for acutely admitted patients in geriatric units: protocol for a cluster randomized controlled trial.

Background: Acutely ill and frail older adults and their next of kin are often poorly involved in treatment and care decisions. This may lead to either over- or undertreatment and unnecessary burdens. The aim of this project is to improve user involvement and health services for frail older adults living at home, and their relatives, by implementing advance care planning (ACP) in selected hospital wards, and to evaluate the clinical and the implementation interventions. Methods: This is a cluster randomized trial with 12 hospital units. The intervention arm receives implementation support for 18 months; control units receive the same support afterwards. The ACP intervention consists of 1. Clinical intervention: ACP; 2. Implementation interventions: Implementation team, ACP coordinator, network meetings, training and supervision for health care personnel, documentation tools and other resources, and fidelity measurements with tailored feedback; 3. Implementation strategies: leadership commitment, whole ward approach and responsive evaluation. Fidelity will be measured three times in the intervention arm and twice in the control arm. Here, the primary outcome is the difference in fidelity changes between the arms. We will also include 420 geriatric patients with one close relative and an attending clinician in a triadic sub-study. Here, the primary outcomes are quality of communication and decision-making when approaching the end of life as perceived by patients and next of kin, and congruence between the patient's preferences for information and involvement and the clinician's perceptions of the same. For patients we will also collect clinical data and health register data. Additionally, all clinical staff in both arms will be invited to answer a questionnaire before and during the implementation period. To explore barriers and facilitators and further explore the significance of ACP, qualitative interviews will be performed in the intervention units with patients, next of kin, health care personnel and implementation teams, and with other stakeholders up to national level. Lastly, we will evaluate resource utilization, costs and health outcomes in a cost-effectiveness analysis. Discussion: The project may contribute to improved implementation of ACP as well as valuable knowledge and methodological developments in the scientific fields of ACP, health service research and implementation science.
