The effect of staff training on agitation and use of restraint in nursing home residents with dementia: a single-blind, randomized controlled trial. Dimensions of care for dementia sufferers in long-term care institutions: are they related to outcomes? Effect of enhanced psychosocial care on antipsychotic use in nursing home residents with severe dementia: cluster randomised trial. The impact of regular multidisciplinary team interventions on psychotropic prescribing in Swedish nursing homes.
Agitation is common in dementia and is associated with use of restraints and use of psychotropic drugs. The aim of this study was to determine whether an education and supervision intervention could reduce agitation and the use of restraints and antipsychotic drugs in nursing homes.
                Four Norwegian nursing homes were randomly allocated to receive either treatment as usual or an intervention consisting of a 2-day educational seminar and monthly group guidance for 6 months. One hundred forty-five residents with dementia (based on medical records and corroborated with a Functional Assessment Staging score >or= 4) completed baseline and 6-month intervention assessments and were included in the analyses. The co-primary outcome measures were the proportion of residents subject to interactional restraint and the severity of agitation using the Cohen-Mansfield Agitation Inventory (CMAI). Patients were assessed at baseline, immediately after completion of the intervention at 6 months, and 12 months after baseline. Comparison of change in the 2 groups was made using repeated-measures analysis of variance (CMAI) and Mann-Whitney test (restraints). The study was conducted from 2003 to 2004.
                The proportion of residents starting new restraint was lower in the intervention than in the control group at 6-month evaluation (P = .02), but no statistically significant differences were found at 12-month assessment (P = .57). The total CMAI score declined from baseline to 6 and 12 months' follow-up in the intervention homes compared to a small increase in the control homes (F2,176 = 3.46, P = .034). There were no statistically significant differences in use of antipsychotic drugs.
                A brief 2-day staff education program followed by continued monthly guidance was able both to improve quality of care by reducing the frequency of interactional restraints and to reduce severity of agitation.

The relationship between SCU status plus separate measures of the dimensions of care and outcomes for dementia sufferers was then investigated.
                Data were drawn from the Intermediate Care Facility Project. The sample (N = 510) included residents with dementia, aged 65 and older, in intermediate care facilities throughout the province of British Columbia. Canada. Longitudinal data included 6 outcomes: cognitive function, behavioral problems of agitation and social skills, physical functioning, and quality of life measured through affect and expressive language skills. Separate multiple linear regression equations were estimated, relating each of these outcomes to 5 dimensions of care: preadmission and admission procedures. staff training and education, nonuse of physical and chemical restraints, flexible care routines and resident-relevant activities, and the environment.
                The results showed there is virtually no clustering of dimensions along SCU/non-SCU lines. Neither SCU status nor the individual dimensions were highly predictive of outcomes. Residents' affect at t1 emerged as a characteristic that was significantly correlated with other outcomes.
                This Canadian research can be added to the few but growing number of rigorous studies that suggest SCUs are not homogeneous and do not necessarily provide better care than non-SCUs. Moreover, it raises questions about the benefits of "best practice" dimensions of care, regardless of SCU status. To evaluate the effectiveness of a training and support intervention for nursing home staff in reducing the proportion of residents with dementia who are prescribed neuroleptics.
                Cluster randomised controlled trial with blinded assessment of outcome.
                12 specialist nursing homes for people with dementia in London, Newcastle, and Oxford.
                Residents of the 12 nursing homes; numbers varied during the study period.
                Training and support intervention delivered to nursing home staff over 10 months, focusing on alternatives to drugs for the management of agitated behaviour in dementia.
                Proportion of residents in each home who were prescribed neuroleptics and mean levels of agitated and disruptive behaviour (Cohen-Mansfield agitation inventory) in each home at 12 months.
                At 12 months the proportion of residents taking neuroleptics in the intervention homes (23.0%) was significantly lower than that in the control homes (42.1%): average reduction in neuroleptic use 19.1% (95% confidence interval 0.5% to 37.7%). No significant differences were found in the levels of agitated or disruptive behaviour between intervention and control homes.
                Promotion of person centred care and good practice in the management of patients with dementia with behavioural symptoms provides an effective alternative to neuroleptics. To evaluate the impact of regular multidisciplinary team interventions on the quantity and quality of psychotropic drug prescribing in Swedish nursing homes.
                A randomized controlled trial.
                A sample of 33 nursing homes: 15 experimental homes and 18 control homes representing 5% of all Swedish nursing homes.
                The sample consisted of 1854 long-term care residents with an average age of 83 years. Seventy percent of the residents were women, and 42% had a documented diagnosis of dementia. An additional 5% had a psychotic disorder, and 7% had a diagnosis of depression.
                Experimental homes participated in an outreach program that was designed to influence drug use through improved teamwork among physicians, pharmacists, nurses, and nurses' assistants. Multidisciplinary team meetings were held on a regular basis throughout the 12-month study period.
                Lists of each resident's prescriptions were collected 1 month before and 1 month after the 12-month intervention. Measures included the proportion of residents with any psychotropic drug, polymedicine, and therapeutic duplication and proportion of residents with nonrecommended and acceptable drugs in each psychotropic drug class, as defined by current Swedish guidelines.
                Baseline results show extensive psychotropic drug prescribing, with the most commonly prescribed drugs being hypnotics (40%), anxiolytics (40%), and antipsychotics (38%). After 12 months of team meetings in the experimental homes, there was a significant decrease in the prescribing of psychotics (-19%), benzodiazepine hypnotics (-37%), and antidepressants (-59%). Orders for more acceptable antidepressants also increased in the experimental homes. In the control homes there was increased use of acceptable antidepressants, but there were no significant reductions in other drug classes.
                There is excessive prescription of psychotropic drugs in Swedish nursing homes. Improved teamwork among caregivers can improve prescribing as defined by clinical guidelines.
There are no identified RCTs investigating the effects of SCUs on behavioural symptoms in dementia, and  no strong evidence of benefit from the available non-RCTs.  It is probably more important to implement best practice than to provide a specialized care environment.  The routine collection of data on behaviour, restraint and psychotropic drug use across multiple nursing home settings offers the best modality for formal evaluation of the benefit or otherwise of SCUs.
