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. Use of restraint amongst institutionalised elderly with dementia and problem behaviour not only remains widespread, but also appears to be accepted as inevitable.
                The aim of this study was to reduce problem behaviour and the use of restraint in demented patients using a staff training program as intervention.
                The study was a randomised single-blind controlled trial and took place in Stavanger, Norway. Four nursing homes were randomised to a control or an intervention group after stratification for size. The intervention consisted of a full day seminar, followed by a one-hour session of guidance per month over six months. The content of the educational program focused on the decision making process in the use of restraint and alternatives to restraint consistent with professional practice and quality care. The primary outcome measures were number of restraints per patient in the nursing homes in one week and agitation as measured with the Brief Agitation Rating Scale (BARS). These were rated before and immediately after the intervention was completed. The assessments were performed blind to design and randomisation group.
                Clinical and demographic variables did not differ between the intervention and control groups at baseline. After the intervention period, the number of restraints had declined by 54% in the treatment group, and increased by 18% in the control group. The difference between the two groups was statistically significant ( p = 0.013). There was a trend towards higher BARS score in the intervention compared to the control group at follow up ( p = 0.052).
                Although the level of agitated behaviour remained unchanged or increased slightly, the educational program led to a significant reduction of the use of restraint in institutionalised elderly with dementia. These results suggest that educational programs can improve the quality of care of people with dementia.

                Cluster-randomized controlled trial with nursing units as the basis for randomization.
                Forty group dwelling units for people with dementia.
                At baseline, there were 184 staff and 191 residents in the intervention group and 162 staff and 162 residents in the control group. At the 6-month follow-up, there were 156 staff and 185 residents (36 newly admitted) in the intervention group and 133 staff and 165 residents (26 newly admitted) in the control group.
                A 6-month education program for all nursing staff.
                Staff knowledge and attitudes and physical restraint use were measured before and after the education program.
                In the intervention group, staff knowledge about and attitudes toward restraint use changed, and the overall use of physical restraints decreased. A comparison including only residents present during the whole study period showed that the level of use was similar between the groups at baseline, whereas it was significantly lower in the intervention group at follow-up. Adjusted analyses showed that the odds of being restrained at follow-up were lower in the intervention group than in the control group. There was no significant change in the number of falls or use of psychoactive medication.
                The results indicate that staff education can increase knowledge, change attitudes, and reduce the use of physical restraints without any change in the incidence of falls or use of psychoactive drugs. To investigate the influence of multisensory stimulations in a Snoezelen room on the balance of individuals with dementia.
                Randomized controlled trial.
                Canadian long-term care home.
                Twenty-four residents (average age 86 years), in a long-term care home diagnosed with dementia, were assigned randomly to intervention and control groups. Nineteen participants completed the study. Interventions: Nine intervention group participants completed 30-minute Snoezelen room sessions twice a week for six weeks. Sessions were guided by participants' preferences for stimulation. Interactions with tactile, visual and proprioceptive sensations were encouraged. Ten control group participants received an equal amount of volunteer visits.
                The Functional Reach Test, the eyes-open Sharpened Romberg and the Timed Up and Go Test with and without dual task, assessed static and dynamic balance at baseline and after the intervention. Falls frequencies were recorded six weeks before, during and after intervention. A journal was kept of observations in Snoezelen room.
                Split-plot MANOVA analyses revealed no significant effects of unstructured Snoezelen room sessions on participants' balance. There were no multivariate effects of time (F(4,14) = 1.13, P = 0.38) or group (F(4,14) = 0.63, P = 0.65). Group membership did not alter falls frequency. However, observations of participants' interactions with elements of the Snoezelen room, such as imagery-induced head and eye movements, vibrating sensations and kicking activities, captured events that can be used to create specific multisensory balance-enhancing stimulations.
                Although the null hypothesis was not rejected, further investigation of a potential to influence balance in individuals with dementia through Snoezelen room intervention in long-term care homes is warranted. To investigate short-term effects of Multi-Sensory Stimulation (MSS) on behaviour, mood and cognition of older adults with dementia, the generalization of effects to day hospital and home environments and the endurance of any effects over time.
                A randomized controlled trial comparing MSS with a credible control of one-to-one activities.
                Fifty patients with diagnoses of moderate to severe dementia were randomized to either MSS or Activity groups. Patients participated in eight 30-minute sessions over a 4-week period. Ratings of behaviour and mood were taken before, during and after sessions to investigate immediate effects. Pre, mid, post-trial, and follow-up assessments were taken to investigate any generalization of effects on cognition, behaviour at the day hospital and behaviour and mood at home and endurance of effects once sessions had ceased.
                Immediately after MSS and Activity sessions patients talked more spontaneously, related better to others, did more from their own initiative, were less bored/inactive, and were more happy, active or alert. Both groups were more attentive to their environment than before, with a significantly greater improvement from the MSS group. At the day hospital, patients in the Activity group improved on their 'speech skills' (amount of speech; initiation of speech), whereas the MSS group remained unchanged during the trial. The MSS group showed a significant improvement in mood and behaviour at home compared to the Activity group whose behaviour deteriorated. No longer-term benefits were shown; indeed, behaviour declined sharply during the month follow-up period.
                Both MSS and Activity sessions appear to be effective and appropriate therapies for people with dementia. The aim of this project was to assess whether outreach visits would improve the implementation of evidence based clinical practice in the area of falls reduction and stroke prevention in a residential care setting.
                Twenty facilities took part in a randomized controlled trial with a seven month follow-up period. Two outreach visits were delivered by a pharmacist. At the first a summary of the relevant evidence was provided and at the second detailed audit information was provided about fall rates, psychotropic drug prescribing and stroke risk reduction practices (BP monitoring, aspirin and warfarin use) for the facility relevant to the physician. The effect of the interventions was determined via pre- and post-intervention case note audit. Outcomes included change in percentage patients at risk of falling who fell in a three month period prior to follow-up and changes in use of psychotropic medications. Chi-square tests, independent samples t-test, and logistic regression were used in the analysis.
                Data were available from case notes at baseline (n = 897) and seven months follow-up (n = 902), 452 residential care staff were surveyed and 121 physicians were involved with 61 receiving outreach visits. Pre-and post-intervention data were available for 715 participants. There were no differences between the intervention and control groups for the three month fall rate. We were unable to detect statistically significant differences between groups for the psychotropic drug use of the patients before or after the intervention. The exception was significantly greater use of "as required" antipsychotics in the intervention group compared with the control group after the pharmacy intervention (RR = 4.95; 95%CI 1.69-14.50). There was no statistically significant difference between groups for the numbers of patients "at risk of stroke" on aspirin at follow-up.
                While the strategy was well received by the physicians involved, there was no change in prescribing patterns. Patient care in residential settings is complex and involves contributions from the patient's physician, family and residential care staff. The project highlights challenges of delivering evidence based care in a setting in which there is a paucity of well controlled trial evidence but where significant health outcomes can be attained.
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.
