Characteristics of implementation sites
insufficiency
Of 36 organisations initially expressing interest, two local authorities subsequently reported changes in priorities, two home care providers were insufficiently resourced, and 13 NHS organisations were seeking funded involvement in research studies. Nineteen organisations engaged in detailed discussion. Five NHS organisations did not proceed due to perceived insufficiency of resources and staffing. Therefore, 14 organisations developed and agreed an implementation plan. These were 10 NHS organisations, three home care businesses and one local authority. Following staff training, one of the home care businesses failed to implement the intervention, and another withdrew due to an unexpected change in the entire senior management team. In addition, the legal department of the local authority objected to the wording of study documents required by the Health Research Authority (HRA), making it impossible to proceed; the HRA, through ethical review, protects and promotes the interests of people involved in health and social care research in England. This left 11 organisations, 10 NHS services and one home care business, that participated in the implementation and evaluation based on agreed implementation plans. Four of the organisations participated in Wave 1 and seven in Wave 2. During Wave 2, the implementation was disrupted by the COVID-19 pandemic.

The majority of trainees were occupational therapists (OTs;
