Implementing shared decision-making in interprofessional home care teams (the IPSDM-SW study): protocol for a stepped wedge cluster randomised trial.

INTRODUCTION: The frail elderly in Canada face a tough decision when they start to lose autonomy: whether to stay at home or move to another location. This study seeks to scale up and evaluate the implementation of shared decision-making (SDM) in interprofessional (IP) home care teams caring for elderly clients or their caregivers facing a decision about staying at home or moving elsewhere.

METHODS: A stepped wedge cluster randomised trial involving 8 Health and Social Service Centers (HSSCs) will be conducted with IP home care teams. HSSCs are the unit of randomisation. A decision guide will be passively distributed to all of the participating HSSCs at the beginning of the project. The participating HSSCs will then be randomised to 1 of 4 intervention start times, separated by 7-month intervals. The primary outcome is whether or not clients and caregivers assumed an active role in decision-making, assessed with a modified version of the Control Preferences Scale. The intervention, targeted at IP home care teams, consists of a 1.5 hour online tutorial and a 3.5 hour skills building workshop in IP SDM. Clients will be eligible for outcome assessment if they (1) are aged ≥65; (2) are receiving care from the IP home care team of the enrolled HSSCs; (3) have made a decision about whether to stay at home or move to another location during the recruitment periods; (4) are able to read, understand and write French or English; (5) can give informed consent. If clients are not able to provide informed consent, their primary caregiver will become the eligible participant.

ETHICS AND DISSEMINATION: Ethics committee review approval has been obtained from the Multicenter Ethics Committee of CISSS-Laval. Results will be disseminated at conferences, on websites of team members and in peer-reviewed and professional journals intended for policymakers and managers.
