Cognitive stimulation therapy for dementia: Provision in National Health Service settings in England, Scotland and Wales

Objectives: Cognitive stimulation therapy (CST) is a brief, non-pharmacological intervention for people with dementia, with an established evidence base for improving cognition and quality of life. It is widely implemented in National Health Service (NHS) settings, but little is known about its naturalistic use. The aim of this survey was to identify and explore inclusion criteria, dose and quality of CST across services in Great Britain (England, Scotland and Wales).Methods: All NHS memory clinics and services for people with dementia were contacted and asked to complete a mixed methods online survey on CST delivery in their service. Questions were centred on who provided CST, who received CST, the dose of CST and any outcomes that were routinely measured.Results: A total of 57/186 services responded, giving a response rate of 30.7%. While the majority reported offering CST (87.7%), there was variability in how this was delivered. Differing inclusion criteria included the use of varying cognitive and behavioural outcome measures, and CST was reported as being offered once and twice weekly. Services also differed in how they evaluated the quality of CST and how this evidence was incorporated for future sessions.Conclusion: While there was a low response rate, this survey indicates that there is significant variability in how CST is used in clinical practice, with many trusts not adhering to the evidence base. To ensure that people with dementia are consistently offered evidence-based, high-quality CST across NHS settings, further standardisation of inclusion criteria, dose and outcomes is needed.
