Nursing home structure and association with agitation and use of psychotropic drugs in nursing home residents in three countries: Norway, Austria and England.

BACKGROUND: Understanding the underlying mechanisms and risk factors leading to agitation is crucial to reduce the severity of agitation and increase quality of life. International comparative studies offer special advantages in elucidating environmental risk factors by providing a wider diversity of environmental exposures such as nursing home structures, health care systems and genetic diversity. METHODS: Baseline data for three different intervention studies in Austria (n = 38), England (n = 302) and Norway (n = 163) were combined posthoc. Patients were grouped according to their dementia severity using the global deterioration scale (GDS), functional assessment staging (FAST) and clinical dementia rating (CDR) scales. For the measurement of agitation, the Cohen-Mansfield Agitation Inventory (CMAI) was used. Data analysis was performed using one-way ANOVA, multivariate and linear regression analysis. RESULTS: CMAI scores were available for 503 subjects with dementia. There were significant differences between the nursing home residents in the three countries regarding age, gender and dementia severity (all p values < 0.001). In the multivariate analyses, the level of agitation differed with higher mean scores in the Austrian (mean (SD) score 51.9(21.8)) compared to UK (43.3(16.1)) and Norwegian (41.6(13.2)) nursing homes (p = 0.002). Similarly, the use of psychotropic drugs differed significantly, with a higher proportion of neuroleptics in UK (48%, p < 0.001) and Austrian (52.6%; p = 0.001) compared to Norwegian (19%) nursing homes. CONCLUSION: We found differences in agitation and antipsychotic drug use which are likely related to structural and cultural differences in nursing homes in three European countries. These findings suggest that structural changes can improve quality of care and quality of life for nursing home residents.

Health and well-being in care staff and their relations to organizational and psychosocial factors, care staff and resident factors in nursing homes.

OBJECTIVE: The aim of this study is to investigate the association of psychosocial factors and patient factors with stress in care staff in nursing homes. METHODS: In this cross-sectional survey, 197 care staff from 13 dementia wards from four nursing homes in the Stavanger region, Norway, participated. Stress in care staff was measured by Perceived Stress Scale, Hopkins Symptom Check List, and subjective health complaints. Agitation in patients was measured with the Cohen-Mansfield Agitation Inventory. Work-related psychosocial factors were measured by General Nordic Questionnaire for Psychosocial and Social Factors at Work (QPSNordic). Data were analyzed using multivariate regression analyses. RESULTS: Psychosocial factors (QPS Nordic) were significantly associated with all the three outcome measures of stress in care staff, whereas agitation was associated with subjective health complaints only. QPS Nordic subscales significantly associated with stress in care staff were those associated with leadership. CONCLUSIONS: Psychosocial factors were more important predictors of carer stress than patient-related factors such as dementia severity and agitation. The findings provide key background information in the planning of interventions to improve conditions for care staff and ultimately for nursing home residents.

Evidence supporting nutritional interventions for persons in early stage Alzheimer's disease (AD).

The purpose of this paper is to grade research evidence supporting nutritional interventions for persons with early stage dementias and to report the recommendations of a consensus panel. Thirty four studies were reviewed in the areas of dietary restriction, antioxidants, and Mediterranean diet with strong support from epidemiological studies found in all three areas. The body of evidence to support nutritional interventions in the prevention and treatment of AD is growing and has potential as a treatment modality following translational studies.

Prevalence and correlates of disruptive behavior in patients in Norwegian nursing homes.

BACKGROUND: Although Behavioral and Psychological Symptoms of Dementia (BPSD) increase with increasing dementia severity, and institutionalization of an individual with dementia is often caused by behavioral symptoms, relatively few studies have explored the prevalence of BPSD in nursing homes. OBJECTIVE: To study the prevalence and correlates of agitation in residents with dementia, in Norwegian nursing homes. METHODS: This study has taken place in dementia wards in four Norwegian nursing homes. To measure agitation in residents with dementia we used the Cohen-Mansfield Agitation Inventory (CMAI), consisting of 29 agitation items. Dementia stage was measured by Functional Assessment Staging (FAST). RESULTS: Two hundred and eleven patients (71% female) were included in the study: mean (SD) age 85.5 (8.4), FAST 4.7 (2.1), CMAI total sumscore 39.5 (12.6). Dementia was present in 167 (79%) subjects. Among those with dementia, weekly occurrence of at least one CMAI item (i.e. a score of 3 or higher) occurred in 75.4% (95% CI 68.4-81.4). Six of the items occurred at least weekly in 20% of the residents with dementia, and 11 of the items, including physical aggression, occurred in less than 5% of the residents. Agitation was associated with more severe dementia (p = 0.001), but not with age and gender. CONCLUSION: Symptoms of agitation were common, but may nevertheless be lower compared to findings in other geographical areas. Further studies are warranted to test this hypothesis, and if confirmed, to explore possible causes for such differences.

The effect of staff training on the use of restraint in dementia: a single-blind randomised controlled trial.

BACKGROUND: Use of restraint amongst institutionalised elderly with dementia and problem behaviour not only remains widespread, but also appears to be accepted as inevitable. OBJECTIVE: 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. METHODS: 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. RESULTS: 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). CONCLUSION: 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.
