Dementia is a common and devastating disease in the elderly. No cure exist and there is an increasing need for care. To improve knowledge on how to provide better care for the patients with dementia in nursing homes, the investigators will carry out a controlled trial using two forms of education and developmental interventions towards the nursing home care staff: a structured framework (VIPS) and dementia care mapping (DCM)to develop person-centred care in a 10 months randomised controlled study. In accordance with the knowledge found in the literature the investigators hypothesize that both VIPS framework and DCM will be more effective than a traditional educational program about dementia provided to the staff in nursing homes. The positive effects will be seen as reduced agitation in patients, less use of psychotropic drugs and improved quality of life. Using VIPS framework and DCM will also have a better effect on staffs' well-being than traditional education in dementia. The aim of the study is to confirm or reject these hypotheses.

This is a controlled intervention trial with three groups of staff recruited from 15 nursing homes in the city of Oslo. The intervention will be carried out over 10 months. Randomization will be done at institutional level. Before randomization all patients in the participating nursing homes should be screened for dementia. This will be done by interviewing the registered nurses in the nursing homes using the Clinical dementia rating scale (CDR), Neuropsychiatric inventory (NPI-Q), Cornell scale for depression in dementia (CSDD). In addition information from the records will be used. Diagnosis of dementia will be made according to ICD-10 criteria, using a diagnostic algorithm that is evaluated in an ongoing nursing home study.

The nursing homes will be randomized in tree groups. Group A - Applying the VIPS- framework to develop Person Centred Care (PCC) and milieu therapy. The staff will be introduced to the model for applying the VIPS-framework to promote PCC in the daily care. A manual including films with information and examples will be distributed to all staff. Two auxiliary nurses are appointed as resource persons (RP) from each ward and one registered nurse (RN) from each nursing home will be trained as coach. The RPs and the leading registered nurse (RN) will plan and lead weekly consensus meetings with the staff in the ward using the VIPS-framework in discussions of concrete care situations. The researches will receive monthly written standard reports on attendance and contents of the consensus meetings from the RPs and can be contacted for support when necessary.

Group B - using Dementia Care Mapping (DCM) developing Person Centred Care and milieu therapy All staff and leaders in the nursing home will be introduced to the DCM- process in a presentation of the method and person centred care as a value base for DCM. A group of 3-5 staff members from each nursing home will be trained as DCM basic users. Dementia Care Mappings (4-6 hours) will be made in each unit in the nursing homes and feed-back (1, 5 hours) will be given to the staff within a week after the mapping. Based on the findings and the reflections in the feed-back session, action plans on how to develop care to selected patients and/or to the group of patients, will be created in the units. The project leader will be responsible for the introduction, mapping and feed-back sessions and give the necessary supervision to create action plans. The leaders and staff in the nursing home units will be responsible for the implementation of the changes to develop practice.The DCM-process will be repeated after 6-8 months

Group C (control group) - traditional education Lectures made as 5 DVD films lasting for 30 minutes, will be given to the nursing home staff on three themes: types of dementia, legal aspects of use of restraints and challenging behavior

The staff in group A and B will receive the same lectures as the staff in the control group.

Effect will be measured on patient and staff level, and measurements will be done at baseline and after 10 months of intervention. Data will be collected by research assistants, who will not take part in the three different intervention programs and not be employed by the nursing homes that are included in the study.
