Abstract

Abstract: Background: The negative effects of behavioural changes among dementia residents and the consequences for caregivers are a major problem in the care of people with dementia. Case conferences (CC) are recommended as a useful method to understand the underlying causes of the behaviour and to plan tailored interventions Objectives: The aim of this article is to describe the effects of two dementia-specific CC models on the prevalence of behaviour that challenges and other secondary outcomes. Design: Stepped-wedge cluster randomized trial. Setting: Nursing homes : The inclusion criterion was the participation of at least two units with a minimum of 30 residents who were mainly cared for in the study units. Participants: A total of 224 residents and 189 staff from six nursing homes in the IdA (Innovative dementia-orientated Assessment system) cohort and 241 residents and 284 staff from six nursing homes in the Neo (Narrative Approach) cohort were included in the study. The inclusion criteria were the following: medical diagnosis of dementia from nursing charts, FAST (Functional Assessment Staging) score > 1, living at least 15 days in the unit, and informed consent. Methods: The nursing homes were randomized to the type of intervention and time point of intervention delivery. The two interventions in the form of the case conference models (Welcome-IdA and -Neo) differed in the type of behaviour analysis method. The intervention duration was seven months. The primary outcome was the change in the prevalence of behaviour that challenges. Secondary outcomes were residents' quality of life, prescription of psychotropic medications, formal caregiver burnout, dementia-related stress, and vocational action competence. The outcomes were measured on seven data points every three months. Linear mixed-effects models were used to analyze intervention effects between the control, intervention and follow-up periods. Results: No differences were found concerning the primary outcome between the control and intervention cohorts for both CC models. Further exploratory data analyses showed a reduction in behaviours such as apathy (18%) and eating disturbances (29%) for the IdA cohort and hallucination (27%) and delusion (28%) in the NEO cohort. Only staff in the IdA cohort demonstrated a reduction in work-related burnout from the control phase to the intervention phase. Conclusion: Specific CC for behaviour that challenges do not decrease the overall prevalence of residents showing changes in behaviour. However, there are indications that the case conferences influence some types of behaviour and reduce the risk factors for work-related burnout
