Evaluation of the Interdisciplinary Care Home-bAsed Reablement Program (I-CHARP) for People Living With Cognitive Impairment and Dementia in Care Homes

Background: Major knowledge and practice gaps exist in aged care home services to support independence of older people with dementia. This research evaluates an adaptation of a community-based rehabilitation model for care homes, namely Interdisciplinary Care Home-bAsed Reablement Program (I-CHARP), by examining whether (and, if so, how) I-CHARP produces its intended effects and how this programme can be practicably implemented, sustained and scaled up across care homes in Australia.

Methods: I-CHARP is a 4-month bio-behavioural-environmental rehabilitation model of care, integrated in care home services, supported through the deployment of an implementation strategy, the Research Enabled Aged Care Homes (REACH) network. It consists of (1) 8-12 full individual sessions and additional eight brief follow-ups per resident, tailored to the resident's needs, delivered primarily by a team of an occupational therapist, registered nurse and other allied health staff; (2) environmental modifications/assistive devices up to the value of $400 per resident; and (3) engagement of intervention care home staff, managers and regular visitors. An overarching evaluation approach is participatory action research using a cluster quasi-experimental design and mixed methods. It involves testing of the implementation strategy (REACH network and other approaches) while observing/gathering information on the intervention (I-CHARP) and related outcomes in three cycles. Participants include residents (aged ≥ 60 years with early stages of dementia) and care staff from 16 care homes. Care quality indicators, health care costs, field notes and semi-structured interviews/focus groups with intervention site staff, regular visitors and managers will provide further insights into I-CHARP processes and implementation issues.

Discussion: In the final phase of the project, an Agile Implementation Playbook will be developed for the delivery of reablement care that can be used in routine practice across care homes in Australia. The study findings will also inform future policy development and strategic directions for dementia care in care homes.
