Versorgungsforschung für demenziell erkrankte Menschen Health Services Research for People with Dementia Symposium Bonn 11.-12. Dezember 2008 (World Conference Center Bonn) Plenary Lectures: PREVENTION AND PSYCHOSOCIAL INTERVENTIONS Outcome measures in dementia care research Abstract (taken from the Abstract Booklet): Establishing a strong evidence base for interventions in dementia care is dependent on the type and relevance of the outcomes measures that are used. Psychosocial interventions in dementia care are emerging, but the evidence for this remains thin. This may not be because the intervention is not robust, but because the primary outcome measure is inadequate. For example if a home care service is being evaluated a measure of subjective caregiver stress may be more appropriate than a measure of well being (Zarit et al. 1999). Poor harmonisation of outcome measures can also make it hard to compare studies and is therefore another obstacle that hampers the growth of a strong evidence base, particularly for psychosocial interventions in dementia. Finally when the evidence for an intervention has been demonstrated, measurement of the quality of implementation into every day practice becomes important. To bridge this gap between the emerging science and associated practice the INTERDEM (Timely INTERvention in DEMentia care across Europe) research group has reviewed, collated and disseminated for use into routine practice, the current evidence base for psychosocial interventions in early stage dementia across Europe (Moniz- Cook & Manthorpe, 2009), harmonised related clinical outcome measures for use in routine practice (Moniz-Cook et al. 2008) and has developed a set of process quality indicators to enhance implementation of evidence based psychosocial interventions into routine practice
In this paper I will first outline some of the difficulties in selecting a primary outcome measure in randomised controlled studies by using recent studies of psychosocial interventions and services in dementia care. Next I will summarise recent studies that harmonised outcome measures for clinical research and developed an evidence based set of quality indicators to enhance implementation of clinical research into routine practice.
