IntroductionWe report on an evaluation of the Just Right approach for planning care for adults with learning disabilities and how it can support culture change. Just Right combines installing a telemonitoring system with training for care managers in person-centred care planning and the interpretation of charts that summarise activity data for their setting. By providing insights into the needs of individuals Just Right allows existing care provision to be reviewed to ensure it is ‘just right’. The Just Right approach can also potentially identify over-care and resources that can released.MethodsA mixed-methods approach was used, triangulating qualitative and quantitative baseline and follow-up data. Qualitative data were collected before and after implementation from focus groups on barriers, enablers, success outcomes and impacts. A theory of change was developed. Detailed data on individual adults with learning disabilities were collected before and after installation of equipment using a linked online survey completed by their care managers.ResultsNine commissioning local authorities were recruited with 33 care providers serving 417 adults with learning disabilities. Issues relating to implementation included staff acceptance, culture, consent, safeguarding, local authority engagement, interpretation of data and residential setting. Changes to care were identified for 20.3% of individuals, with 66% of providers not identifying any changes because Just Right confirmed that they were providing the right level of support.DiscussionBy combining telemonitoring and person-centred care planning, Just Right provides a holistic approach and necessary information for conversations amongst stakeholders about the care needs of adults with learning disabilities. Depending on how it is introduced, and the nature of conversations held, the Just Right approach can potentially change culture, leading to improved outcomes.
