Objective Although the number of elderly residents living in assisted living (AL) facilities is rising, few studies have examined the AL physical environment and its impact on resident well-being. We sought to quantify the relationship of AL physical environment with resident outcomes including neuropsychiatric symptoms (NPS), quality of life (QOL), and fall risk, and to compare the effects for demented and non-demented residents. Methods Prospective cohort study of a stratified random sample of 326 AL residents living in 21 AL facilities. Measures included the Therapeutic Environmental Screening Scale for Nursing Homes and Residential Care (TESS-NH/RC) to rate facilities and in-person assessment of residents for diagnosis (and assessment of treatment) of dementia, ratings on standardized clinical, cognitive, and QOL measures. Regression models compared environmental measures with outcomes. TESS-NH/RC is modified into a scale for rating the AL physical environment AL-EQS. Results The AL Environmental Quality Score (AL-EQS) was strongly negatively associated with Neuropsychiatric Inventory (NPI) total score (p < 0.001), positively associated with Alzheimer Disease Related Quality of Life (ADRQL) score (p = 0.010), and negatively correlated with fall risk (p = 0.042). Factor analysis revealed an excellent two-factor solution, Dignity and Sensory. Both were strongly associated with NPI and associated with ADRQL. Conclusion The physical environment of AL facilities likely affects NPS and QOL in AL residents, and the effect may be stronger for residents without dementia than for residents with dementia. Environmental manipulations that increase resident privacy, as well as implementing call buttons and telephones, may improve resident well-being. Copyright © 2010 John Wiley & Sons, Ltd.

Objectives Given recent evidence that activity participation may reduce functional decline, the effect of activity on resident ability to remain in assisted living (AL) is of interest. This study examines the relationship between participation in activities and the length of time residents remain in AL. Methods The data reported here were gathered in the initial phase of the Maryland Assisted Living Study (MDAL), an epidemiologic study of psychiatric disorders in AL. A stratified, random sample of 198 residents of 22 AL facilities in central Maryland was evaluated using a number of cognitive, behavioral, general health, and functional assessments. The total amount of time each resident spent in group and solitary activity in the prior month was quantified. The dependent variable, time to discharge (TTD), was the number of days between the date of initial assessment by the study team and the date of death in AL, discharge, or administrative censoring. Results Greater levels of activity participation at baseline are associated with longer TTD in an univariate Cox proportional hazards model. After adjustment for global cognitive functioning, general medical health, and mobility, greater activity participation remained associated with longer TTD in AL (p = 0.017). Conclusions Higher levels of activity are associated with longer retention in the AL setting. This effect appeared to be independent of other potentially confounding factors such as general health, cognitive impairment, and mobility. This finding is consistent with the hypothesis that engagement in activities delays functional decline, but further longitudinal research is needed to understand this finding.

Objectives To describe patterns of Acetylcholinesterase inhibitor (ACI) use in an Assisted Living (AL) population, and the association of ACIs with retention in AL. Methods As part of the Maryland Assisted Living Study (MD–AL), 198 residents of 22 ALs were evaluated. Dementia was diagnosed in 134, and specifically Alzheimer's disease (AD) in 79, by an expert consensus panel. Data was collected on ACI agent and dose. Vital status and location were recorded every 6 months. Other data included age, duration of residence, general medical health rating (GHMR), Mini-Mental State Examination (MMSE), Neuropsychiatric Inventory (NPI), Cornell Scale for Depression in Dementia (CSDD) and number of non-psychiatric medications. Results The overall ACI treatment rate was 31%. 34.5% of participants with mild to moderate AD were taking ACIs. Only two in seven participants taking rivastigmine were taking an adequate dose. Participants with AD on ACI's did not differ significantly from those not on ACI's in any of the secondary measures except age and duration of residence, those on the agents being somewhat younger and more recently admitted. For participants with AD, only ACI use was significantly associated with retention in AL at 6 months, with a relative risk of death or discharge to higher level care of 0.217. Baseline MMSE was associated with retention for those with non-AD dementia. In a survival analysis ACI use was associated with 228.75 days longer retention in participants with AD. Conclusion ACIs have low rates of use in AL and are associated with better retention for residents with AD. Copyright © 2007 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Objective To estimate the frequency and correlates of insomnia and daytime sleepiness among people with dementia in AL facilities. Methods Participants were randomly selected from 22 different assisted living facilities in Maryland. A total of 124 dementia participants were included in the analysis. All participants were rated on an 11-item sleep questionnaire regarding insomnia and daytime sleepiness. Results Sleep disturbance was present in 59.2% of people with dementia. Of the total sample, 21.8% had insomnia only (IN); 21.6% had excessive daytime sleepiness only (DS); and 16.8% had both IN and DS. 40.8% had no sleep disturbance. IN and DS scores were not significantly associated with each other (r = 0.07, p = 0.43). Of those in the IN group, the majority had mild and moderate dementia and of those in the DS only group the majority had severe dementia. Those with IN only performed the best and DS only performed the worst on both cognitive measures (the Mini Mental State Examination) (F = 3.26, p = 0.014), and on physical measures (the physical subscale of the psychogeraitric dependency rating scale) (F = 6.09, p < 0.001). There was no significant difference between the groups on the Cornell scale for depression in dementia. Conclusion The frequency of insomnia and daytime sleepiness in dementia subjects in AL is similar to that found in nursing homes. Daytime sleepiness is associated with poorer cognitive and day-to-day functioning. Effective management of DS may lead to improved functioning in the AL residents. Insomnia is associated with the best outcomes, even better than those with no sleep disturbance. This finding needs to be replicated. Copyright © 2007 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Objectives To compare the demographic, clinical, and psychiatric characteristics of residents living in small (≤15 beds) and large assisted living (AL) facilities in the United States. Methods One hundred and ninety-eight residents in 10 large and 12 small assisted living facilities were comprehensively assessed as part of the Maryland Assisted Living Study (MD-AL). The presence or absence of dementia and psychiatric disturbances and the facilities' recognition and management of these disorders were compared across the two types of AL. Aspects of care delivery were also compared. Results Small facilities had a higher prevalence of dementia (81%) compared to larger facilities (63%) and the mean Mini-Mental State Examination (MMSE) across all residents in small facilities (mean 13.04) was than in large facilities (mean 19.93)(p = 0.000). Almost all (98%) of the residents of small homes carried a diagnosis of a dementia or other psychiatric diagnosis, compared to 74% of residents in large facilities (p < 0.001). Psychosis in particular was more prevalent in the smaller homes and the mean Neuropsychiatric Inventory score, a measure of neuropsychiatric symptoms, was higher compared to large homes. Falls were more common in larger homes despite a greater number of personal care hours per week. The use of safety devices and restraints was significantly less common in large facilities compared to smaller homes, where ‘geri-chair’ and bedrails were more often used. Conclusions Rates of dementia and psychiatric disorder differ in assisted living facilities depending on size of facility. Copyright © 2006 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

We used a cross-sectional study to examine the correlates of caregiver-rated quality of life (QOL) in 198 randomly selected residents from a stratified random sample of 22 assisted living facilities in central Maryland. We measured QOL by using the Alzheimer's Disease-Related Quality of Life Questionnaire. In general, despite cognitive impairment, residents in assisted living were rated as having a high QOL. In a multivariate regression, we found that nonmood neuropsychiatric symptoms were the strongest correlate of QOL, explaining 37% of the variance. Depressive symptoms, functional dependence, marital status, and cognition also contributed to the model, but only minimally. Because of the strong association of neuropsychiatric symptoms with QOL, special attention should be given to their recognition and amelioration. [ABSTRACT FROM AUTHOR]

IntroductionA majority of the elderly suffer from some sort of sleep disturbance. Common sleep disturbances are insomnia and excessive daytime sleepiness. There are no published studies on the prevalence of sleep disturbance in the assisted living (AL) setting. ObjectiveTo estimate the prevalence, types, and associations of sleep disturbance in a stratified random sample of AL residents, and to explore the effect of sleep disturbance on cognitive and physical functioning, as assessed by the Mini- Mental State Exam (MMSE) and the Psychogeriatric Dependency Rating Scale (PGDRS). MethodsParticipants were 198 randomly selected assisted living residents in 22 Maryland facilities. Participants were rated on an 11-item sleep questionnaire regarding insomnia and daytime sleepiness. ResultsSleep disturbance was present in 69% of residents, insomnia (IN) in 42% and excessive daytime sleepiness (DS) in 34.6%. IN and DS scores were not significantly correlated(r = 0.10, p = 0.19). Use of hypnotics, sedating antidepressants, and depression were associated with insomnia. Depression and poor general medical health were associated with daytime sleepiness. On a cognitive task (Mini Mental State Examination) participants with insomnia only out-performed participants with no sleep disturbance and daytime sleepiness; on a measure of physical function (PsychoGeriatric Dependency Rating Scale- physical domain), participants with insomnia fared better than those with daytime sleepiness only and those with both insomnia and daytime sleepiness. Participants with DS only performed worse on both measures compared to those with no sleep disturbance, those with insomnia only, and those with both insomnia and daytime sleepiness. ConclusionThe prevalence of sleep disturbance in AL is similar to that reported in nursing homes. Daytime sleepiness is associated with poorer cognitive and day-to-day functioning, while insomnia is associated with better outcomes. Effective management of DS may lead to improved functioning in the AL residents. Copyright © 2005 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Purpose:We conducted this study to determine whether neuropsychiatric symptoms and environmental characteristics are associated with quality of life in assisted living residents with dementia.Design and Methods:We used a cross-sectional study of 134 residents from 22 facilities and employed the Alzheimer's Disease-Related Quality of Life Scale and the Neuropsychiatric Inventory. A scale was developed to capture the homelike climate of each facility. Linear regression analyses were used to estimate the relationship of neuropsychiatric symptoms and homelike climate with quality of life, controlling for sociodemographics, cognition, functional dependence, and physical health. Exploratory analyses and graphical techniques were employed to test for environmental-level moderating effects.Results:Agitation, depression, apathy, and irritability were significant predictors of quality of life, explaining 29% of the variance. Neither facility size nor homelike environment was significantly associated with quality of life in univariate analyses. Size of facility moderated the relationship between agitation and quality of life.Implications:Neuropsychiatric symptoms impair quality of life in residents with dementia. Further research should investigate the role of other environmental aspects. [ABSTRACT FROM AUTHOR]

Background: Assisted living is a popular residential option for older individuals, yet little research has been done on people choosing this option. This study examines predictors of functional impairment in assisted living residents in the domains of cognition, mood, and health.Methods: An experienced team of neuropsychiatrists, nurses, and technicians using a number of cognitive, behavioral, health, and functional status tests and a cross-sectional study design assessed 198 residents of 22 assisted living facilities in Maryland. Data from these evaluations were used in univariate and multiple regression models to identify predictors of functional impairment, operationalized as the sum of the scores on two scales, one measuring impairment in basic activities of daily living and one measuring impairment in instrumental activities of daily living.Results: Greater cognitive impairment, worse depression, and worse medical health were significant independent predictors of functional impairment, together explaining a sizeable portion of the variance (adjusted R2=0.434). None of the demographic variables examined individually, including age and education, was predictive of functional impairment. In an analysis of specific cognitive domains, executive dysfunction, impairment of visuospatial skills, and amnesia were significant predictors of impairment, whereas inattention was not.Conclusion: Executive dysfunction, apraxia, memory impairment, depression, and general medical health are all significant predictors of functional impairment in assisted living residents, with executive dysfunction being the strongest. These results may be instrumental in developing a more efficient model of care for residents of assisted living facilities, one based on having accurate predictive models of degree of impairment.

Background Assisted living (AL) is the fastest growing segment of residential long-term care in the US. At least half of the estimated 1 million AL residents have dementia or cognitive impairment, with many AL facilities offering specialized dementia services. Little research has been done on the demographics, outcomes, or clinical variables of this population. Methods Participants were a cohort of 144 residents admitted to the AL unit of Copper Ridge, a specialized dementia-care facility. Comparison samples included 737 patients with dementia residing in other locations (home, nursing home, and other assisted living facilities). Selected measures of cognition, behavior, medical health, and function were taken at admission to AL and at 6-month intervals. Results When compared with residents of the dementia-specialized AL facility, dementia patients at home were younger, less cognitively impaired, and less likely to exhibit wandering, delusions, or aggression. Residents of a dementia-specialized nursing home had more cognitive impairment, greater medical comorbidity, and were more dependent on caregivers. The 2-year mortality rate in the dementia-specialized AL was 23%, significantly lower than rates reported for nursing homes. Primarily due to increasing care needs, most residents in the specialized AL relocated to a nursing home after a median stay of 10.9 months. Depression, falling, and wandering were significant predictors of the transition. Conclusion Dementia-specialized AL facilities occupy a unique position in the long-term care continuum that is distinct from home-care and nursing home facilities. This research is the first step toward understanding the significant dementia population residing in assisted living. Copyright © 2000 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
