Description of intervention(s) / exposure
This is a type 2 hybrid effectiveness-implementation randomised controlled trial to (1) determine the effectiveness of the ‘Tailored iSupport’ intervention for carers and people with dementia and (2) to evaluate the effectiveness of the implementation strategies applied to embed the ‘Tailored iSupport’ into the routine services of aged care organisations in real-world settings. The study will also explore the experiences of carers, frontline staff and facilitators in the project. The interventions in the study are outlined in the following:
Carers in the ‘Tailored iSupport’ group will be assigned to a trained facilitator, who is a health professional or social care professional with expertise in dementia care. The facilitators will undergo 3 x 2 hours online workshops over a 2-week period and the training sessions will be provided 6 weeks prior to initiation of the intervention. The training sessions will be relative to delivering the intervention including: 1) Introduction to the project; 2) being an effective facilitator and 3) recruitment, data collection and outcome measures used in the project. The CIs in the project will provide the training sessions. Moreover, facilitators will participate in a 30-minute online debrief and coaching session every 2 weeks with the CIs in the project during the intervention period to ensure their facilitation alights with the intended project outcomes and to help them with problem-solving skill development.
The facilitators will provide individualised support to carers by engaging them in: 1) relevant iSupport modules: The facilitator will assess carers’ individualised needs in the program in an individual meeting lasting 45-60 minutes 2 weeks prior to the intervention using the ‘Risk Appraisal Measure’ (Adapted from Czaja et al. 2009). The facilitator will recommend learning modules, for example ‘Module 5 Dealing with changed behaviours’ when the carer reports sudden/worrisome changes in care recipient’s memory and mood. 2) monthly peer support group meetings lasting about 30-45 minutes (online or face-to-face): The meeting will include up to 8 carers. 3) weekly text messages extracted from iSupport to target carers’ learning needs; 4) resources/services tailored to their needs: Carers are encouraged to make individual appointments with their facilitator to request assistance to access and utilise resources/services when their care recipients experience changes, for example in the case of sudden changes in behaviours, the facilitator will recommend GP visit to identify the causes or refer them to Dementia Support Australia (in Australia’s study sites only). Facilitators will maintain a portfolio to record all contact instances with carers throughout the intervention period. 5) The facilitators will provide monthly staff training on iSupport during the intervention period using the existing paid staff development time, provide practical support for frontline staff in the workplace regarding partnership with carers. The intervention will last 6 months.

Eligibility
Key inclusion criteria
This study will be undertaken in aged care organisations in Australia and Community Health Centres (CHCs; primary care managed by general practitioners and registered nurses) in China. In Australia, participants will be recruited in community aged care settings managed by three Chinese ethno-specific aged care organisations based in Adelaide (South Australia) and Sydney (New South Wales). In China, participants will be recruited in 6 CHCs in Xian’s Shanxi Province and in Zunyi, Guizhou Province respectively. There are three participant categories, namely Chinese carers of people with dementia (PWD), frontline staff and iSupport facilitators, in the study.
Inclusion criteria for Chinese carers of people with dementia (PWD): aged 18 years or over; caring at least twice a week for an adult living with dementia. If a care recipient has no formal dementia diagnosis but meets cognitive impairment using the "AD8 Dementia Screening Interview" (Li et al. 2012). Exclusion criteria: carers have severe mental health conditions or terminal illness themselves; are involved in other studies or participated in the previous iSupport RCT trial.
Inclusion criteria for frontline staff: frontline staff involved in the care of PWD and the carers to the study will be invited to participate.

Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment is ensured by:
1. Participants will be assigned a code by research assistant
2. The biostatistician who has no contact with participants will randomly assign code into groups.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
After baseline data collection, carers will be randomly assigned to receive either the tailored iSupport or the usual iSupport. To ensure the two groups are of equivalent size, a randomly generated block size of 4 will be used to allocate carers to one of the two treatment groups for each recruitment site. An independent clinical trial management centre will provide randomisation services to the study.

Efficacy
Statistical methods / analysis
Quantitative data will be analysed on an intention-to-treat basis based on group assignments. A multivariate mixed effect linear regression model will be applied to fit linear mixed models and to examine the primary and secondary outcomes between groups. As the outcome occurs for each individual with repeated time points, the mixed effect models will capture both fixed effects and random effects within the hierarchical structure of the data. The fixed effects, including group effect, time effect and group x time interaction, will be analogous to the regression coefficients. The random effects represent the estimated variability in the intercept to account for repeated measurements. The model will be adjusted by the baseline measure of outcome variable. The maximum likelihood estimate procedure will be used to compare significant differences in primary and secondary outcomes over time and between groups. Univariate models will be first used, then multivariate modelling will be undertaken by adding variables considered clinically important or statistically significant from the univariate model to adjust for confounding effects between variables. A series of models will be undertaken by adding and subtracting variables, with changes in model fit assessed by log likelihood to choose the final multivariate model. The two-sided test will be performed for all analyses and the level of significance will be set at p <0.05. All analyses will be performed using Stata software version 16.1. A Research Assistant, who will be blinded to group assignments, will undertake data analysis and will be supervised by Associate Professor Ullah, a biostatistician.

Summary
Brief summary
The research project aims to (1) to determine the effectiveness of the ‘Tailored iSupport’ intervention for carers and people with dementia; and (2) to evaluate the effectiveness of the implementation strategies applied to embed the ‘Usual support’ and the ‘Tailored iSupport’ into the routine services of aged care organisations in real-world settings. The study will also explore the experiences of carers, frontline staff and facilitators in the project.
The hypotheses tested in the study are described in the following:
1. Carers receiving the ‘Tailored iSupport’ will report 1) a higher level of QoL; 2) a higher level of Self-Efficacy; 3) a significantly higher level of QoL for the person they care for via a proxy rating; 4) fewer unplanned hospital admissions, less emergency department use and a lower level of permanent admission into residential aged care by the person they care for; 5) better quality care experiences of persons with dementia via proxy ratings, compared to those in the ‘Usual iSupport group’.

Public notes
This trial is phase 2 of the project. Prior to the trial, we undertook phase 1 of the study which was a co-design phase with stakeholders to identify implementation strategies in phase 2 using a qualitative study design. During the co-design phase, facilitators raised their concerns about the relevance and the length of the assessment tool, ‘Carer learning needs assessment tool’ (Sadak et al., 2015; 35 items), used to assess carers’ needs for tailored support. To address their concerns, the research team undertook a focused literature review and identified the ‘Risk Appraisal Measure or RAM’ (Czaja et al. 2009) which has only 16 items and shows clean instructions for facilitators to identify and meet carers’ needs. However, the RAM has not been translated into Chinese. Therefore, we undertook a pilot study within phase 1 in one of our study sites to translate the English version of RAM into Chinese and test carers’ understanding of the 16 statements used in the assessment tool. We recruited five carers to work with the facilitator in the pilot study. The time period of the pilot study was between 28/03/2023 and 15/05/2023. The results indicate that the assessment tool was easy for the facilitator to operate, and carers understand the 16 statements. The data collected in the pilot study will be reported in our phase 1 of the project as part of co-design activities with stakeholders.
