The study uses the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework to assess the Carer Matters programme for dementia caregivers in Singapore. A parallel mixed-methods study design is applied to assess the programme's feasibility and effectiveness.

A mixed-methods study to (1) Evaluate the feasibility of Carer Matters for caregivers of PwD and to (2) Explore perspectives of key stakeholders who are directly or indirectly involved with Carer Matters, to better understand the potential sustainability of this framework.

The objectives of are as follows:

1. To explore the perceptions, attitudes and beliefs of family caregivers, healthcare workers and community partners towards Carer Matters.
2. To explore the barriers and facilitators of acceptance and implementation of Carer Matters.
3. To gain insights into the perceived demand of Carer Matters.
4. To gain insights into the family caregivers' preliminary responses to and outcomes from Carer Matters.

The study will involve six inpatient wards of a 1,700-bedded tertiary care hospital which are piloting Carer Matters. These wards comprise of four acute wards and two sub-acute wards. They are selected as they admit a comparatively greater number of patients with dementia than other wards in the hospital. The study will be conducted over 12 months.

Quantitative data is based off programme data collected from all caregivers who undergo Carer Matters. Hence, it will consist of all dementia caregivers whose care recipient is admitted into the pilot wards and agree to participate in Carer Matters.

Qualitative data is based off interviews of key stakeholders of the different components of the Carer Matters programme. The key stakeholders comprises: (1) Family caregivers of PwD (n = 25 to 30), (2) Ward nurses (n= 8 to 10), (3) Care support nurses (n = 2 to 3), (4) Intervention programmes facilitators and standardized patients (n = 3), (5) Community partners and hospital leaders (n = 4), and (6) Other clinicians - medical social workers, physiotherapists, occupational therapists and doctors (n = 4 to 5).

Both qualitative and quantitative data will be triangulated using the RE-AIM framework address the research objectives of the study. These insights will then be used to generate an updated Theory of Change model explaining how SHARE improves caregiver capacity for sustained caregiving. This final model will reflect the processes and mechanisms of Carer Matters that contribute towards the short, medium and long-term outcomes intended, and can serve as a guide for future researchers and practitioners.
