12-month incidence, prevalence, persistence, and treatment of mental disorders among individuals recently admitted to assisted living facilities in Maryland.

BACKGROUND: To estimate the 12-month incidence, prevalence, and persistence of mental disorders among recently admitted assisted living (AL) residents and to describe the recognition and treatment of these disorders. METHODS: Two hundred recently admitted AL residents in 21 randomly selected AL facilities in Maryland received comprehensive physician-based cognitive and neuropsychiatric evaluations at baseline and 12 months later. An expert consensus panel adjudicated psychiatric diagnoses (using DSM-IV-TR criteria) and completeness of workup and treatment. Incidence, prevalence, and persistence were derived from the panel's assessment. Family and direct care staff recognition of mental disorders was also assessed. RESULTS: At baseline, three-quarters suffered from a cognitive disorder (56% dementia, 19% Cognitive Disorders Not Otherwise Specified) and 15% from an active non-cognitive mental disorder. Twelve-month incidence rates for dementia and non-cognitive psychiatric disorders were 17% and 3% respectively, and persistence rates were 89% and 41% respectively. Staff recognition rates for persistent dementias increased over the 12-month period but 25% of cases were still unrecognized at 12 months. Treatment was complete at 12 months for 71% of persistent dementia cases and 43% of persistent non-cognitive psychiatric disorder cases. CONCLUSIONS: Individuals recently admitted to AL are at high risk for having or developing mental disorders and a high proportion of cases, both persistent and incident, go unrecognized or untreated. Routine dementia and psychiatric screening and reassessment should be considered a standard care practice. Further study is needed to determine the longitudinal impact of psychiatric care on resident outcomes and use of facility resources.

Childless Elders in Assisted Living: Findings from the Maryland Assisted Living Study.

We compared data drawn from a random sample of 399 current assisted living (AL) residents and a subsample of 222 newly admitted residents for two groups: childless AL residents and AL residents with children. The percentage of childless AL residents (26%) in our study was slightly higher than US population estimates of childless persons age 65 and over (20%). In the overall sample, the two groups differed significantly by age, race and women's years of education. The childless group was slightly younger, had a higher percentage of African American residents, and had more years of education than the group with children. In the subsample, we looked at demographic, functional, financial and social characteristics and found that compared to residents with children, fewer childless residents had a dementia diagnosis, received visits from a relative while more paid less money per month for AL and reported having private insurance. As childlessness among older adults continues to increase, it will become increasingly important to understand how child status affects the need for and experience of long-term care.

Correlates of functional dependence among recently admitted assisted living residents with and without dementia.

OBJECTIVES: To describe and contrast functional dependency (FD) levels among recently admitted AL residents with and without dementia and to assess the differential contribution of cognitive, behavioral, medical, and social factors on FD within each group. DESIGN: A cross-sectional study. SETTING: A random sample of 28 AL facilities in the Central Maryland region. PARTICIPANTS: Two hundred and sixty-two AL residents assessed less than 1 year after admission. MEASUREMENTS: Participants were given comprehensive in-person dementia assessments. Cognitive, behavioral, medical, and social factors were also assessed. FD was operationalized as impairment in activities of daily living. RESULTS: The 59% of residents with dementia had higher levels of FD (P < .001) and were more likely to require assistance in all assessed task-specific ADL domains (P < .001) except mobility (P = .653). In multivariate models, global cognition, medical health status, and presence of diabetes explained 43% of the variance in FD in the dementia group. Twenty-five percent of the variance in FD was explained by depression, neuropsychiatric symptoms, and global cognition in those without dementia. CONCLUSIONS: Recently admitted AL residents have substantial levels of FD. FD is higher among residents with dementia compared with those without and the association of cognitive, mental health, and medical variables with FD differ as a function of dementia status. Future research should examine how these dimensions affect FD longitudinally and whether they may serve as targets for interventions and quality of care improvement initiatives.

Surrogate decision makers' understanding of dementia patients' prior wishes for end-of-life care.

OBJECTIVE: This study examines how surrogate decision makers for dementia patients developed an understanding of patient preferences about end-of-life (EOL) care and patient wishes. METHODS: Semistructured interviews were conducted with 34 surrogate decision makers for hospice-eligible nursing home patients with dementia. The data were content analyzed. RESULTS: Most surrogates reported that patients had previously completed an advance directive (59%), discussed preferences for EOL care (56%), or done both (38%). Catalysts for and barriers to completing an advance directive or having EOL care discussions included factors that were both intrinsic and extrinsic to the patient. The most commonly reported wish for EOL care was to not be kept alive by "machines" or "extraordinary measures." DISCUSSION: Health care providers may be able to assist patients and families by normalizing discussions of dying, encouraging advance care planning, helping them identify goals for EOL care, and providing information to support treatment decisions consistent with patients' wishes.

The spectrum of medical illness and medication use among residents of assisted living facilities in central Maryland.

BACKGROUND: Although increasing numbers of older adults are living in assisted living facilities, there is little information on the types and amount of chronic medical illness and the medications required by such residents. To better inform efforts to optimize care in this setting, we sought to quantify chronic medical illnesses and their treatment. METHODS: Medical diagnoses and treatments were derived from chart reviews and interviews of 198 residents of 22 randomly selected assisted living facilities (AL) in central Maryland. To evaluate the burden of medical illnesses, chronic conditions were categorized and quantified according to general (organ system) diseases, as well as 7 specific long-term care Clinical Practice Guidelines (CPG). Using logistic regression, we calculated the associations between facility-level characteristics and those residents with a) conditions from 3 or more general disease categories and, b) 2 or more CPG conditions. To evaluate medical treatment complexity, we categorized oral and certain non-oral medications, as well medications that typically require additional monitoring. RESULTS: Almost one-half (46%) of AL residents had chronic conditions in 3 or more different general disease categories and one-fourth (25.2%) had 2 or more specific Clinical Practice Guideline (CPG) conditions. Residents with chronic conditions in 3 or more different general disease groups were more likely to live in larger facilities; otherwise, no other facility-level characteristics that we assessed were associated with residents having conditions from 3 or more general disease categories or 2 or more CPG conditions. One-half of all residents were taking medications that typically require additional monitoring and 25% of residents were receiving treatments of respiratory inhalers, eye drops and/or injections. CONCLUSIONS: Many AL residents have multiple medical illnesses of different types and complexity. Given the increasing role of AL providers in the management of such conditions, appropriate adjustments in care provision will be needed for facilities to meet the needs of these residents.

Improper sexual behaviors in elders with dementia living in residential care.

OBJECTIVES: There exists little information describing the spectrum and correlations of sexual behaviors manifested by elders with dementia living in residential care. METHODS: Data are from a retrospective case-control study of improper sexual behaviors manifested by 165 elders with dementia living in a residential care facility in 2005. RESULTS: Three types of behavior were evident: (1) intimacy-seeking, (2) disinhibited, and (3) nonsexual. Intimacy-seeking behaviors were associated with Alzheimer disease, and disinhibited behaviors with non-Alzheimer dementias. Behavior type was associated with dementia severity. CONCLUSIONS: Delineation of the types of improper sexual behaviors occurring in dementia has practical implications for practice and research. Progress will require prospective studies with systematic ascertainment of cases and variables, and recruitment from large sampling frames.

Medication use in nursing home residents with advanced dementia.

OBJECTIVE: To describe medication usage in nursing home residents with advanced dementia, to identify how this usage changed as patients advanced towards death, and to identify correlates of increased medication usage. METHODS: Prospective cohort study (CareAD) during which data on medication prescription were extracted from medical records at regular intervals using standardized extraction procedures. RESULTS: Patients (n=125) were prescribed a mean of 14.6 medications during the 6 months prior to study enrollment. In a subgroup of patients who died during the study (n=88), as the time of death approached, the total number of medications prescribed did not vary but the types of medications prescribed did change, with an increase in palliative medications such as opiate analgesics and a decrease in other medication classes such as antibiotics, anti-dementia agents, cardiovascular agents, and psychotropic agents, among others. In linear regression analyses, total medication prescription at study entry was associated with study site, antibiotic treatment, presence of cardiovascular disease, and treatment of gastrointestinal or dermatological conditions. CONCLUSIONS: Nursing home residents with advanced dementia are prescribed a large number of medications from numerous medication classes and prescribing patterns change over time. Further study is needed to determine the ideal approach to treating chronic medical problems at the end of life in this patient population.

Anxiety symptoms among assisted living residents: implications of the "no difference" finding for participants with and without dementia.

Anxiety is a distressing experience at any age but may be particularly disabling when coupled with dementia. Dementia-related anxiety is associated with a range of additional problems among community-dwelling older adults, but little is known about its occurrence in assisted living environments. The purpose of this article is to describe the prevalence of anxiety symptoms among older adults who participated in Phase I of the Maryland Assisted Living Study, a cross-sectional study of 198 participants who underwent comprehensive dementia evaluations. Participants with dementia diagnoses (n=134) were compared with those without dementia (n=64) using two measures of anxiety. Anxiety was common in both groups: 22% of each group were assessed to have one or more anxiety symptoms using proxyrated methods, and 45% had at least mild anxiety using direct observation and interview. Factors that contribute to variability in reports of dementia-related anxiety are reviewed.

The association between activity participation and time to discharge in the assisted living setting.

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.

Insomnia and daytime sleepiness in people with dementia residing in assisted living: findings from the Maryland Assisted Living Study.

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.

Acetylcholinesterase inhibitors in assisted living: patterns of use and association with retention.

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.

Effect of dementia and treatment of dementia on time to discharge from assisted living facilities: the Maryland assisted living study.

OBJECTIVES: To estimate the association between dementia and time to discharge from individual assisted living (AL) facilities and examine, in residents with dementia, factors associated with shorter duration of residence in individual AL facilities. DESIGN: Prospective cohort study. SETTING: Twenty-two AL facilities in central Maryland. PARTICIPANTS: Stratified random sample of 198 AL residents followed for a median of 18 months. MEASUREMENTS: Detailed assessments to diagnose dementia; assess treatment of dementia; and rate clinical; cognitive, functional, and quality-of-life measures. RESULTS: Residents with dementia remained in a facility 209 fewer days at the median (P=.001) than residents without dementia. After adjustment for other variables, lack of treatment for dementia (P=.01) and more-serious medical comorbidity (P=.02) were associated with earlier discharge in participants with dementia. Impaired mobility and limited activity participation had weaker associations with earlier time to discharge. CONCLUSION: Dementia may accelerate time to discharge, and its treatment may attenuate this effect. The hypothesis that the detection and treatment of dementia might delay discharge from AL should be tested in randomized trials.

A comparison of small and large assisted living facilities for the diagnosis and care of dementia: the Maryland Assisted Living Study.

OBJECTIVES: To compare the demographic, clinical, and psychiatric characteristics of residents living in small (< or = 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.

Health problems and correlates of pain in nursing home residents with advanced dementia.

This study describes the health problems and comorbid illnesses of nursing home (NH) residents with advanced dementia (n=123) and identifies correlates of staff-identified pain. Study participants were residents of 3 NHs in Maryland, their surrogate decision makers and their physicians. Residents' cognitive function was assessed at study enrollment, and their medical records were reviewed to identify all health problems/illnesses and use of pain medications during the 6 months before their enrollment. The most prevalent health problems were skin problems (95%), nutrition/hydration problems (85%), psychiatric/behavioral problems (85%), gastrointestinal problems (81%), and infections (80%). Sixty-three percent of residents had recognized pain, and 95% of those residents received pain medications. In a multivariate regression analysis, staff-identified pain was associated with aspiration (P=0.008), peripheral vascular disease (P=0.021), musculoskeletal disorders (P=0.032), higher cognitive function (P=0.013), and use of pain medications, including non-opiates (P=0.004) and the combination of opiates and non-opiates (P=0.001). NH residents with advanced dementia experience a complex mixture of multiple chronic and acute comorbidities. These results suggest the need for clinicians in long-term care facilities to be vigilant in assessing and treating pain, particularly as cognitive function declines in those with advanced dementia.

Depression in assisted living is common and related to physical burden.

OBJECTIVE: The objective of this study was to obtain a direct estimate of the prevalence of depression, its associated factors, and rates of treatment among residents of assisted living (AL) facilities in central Maryland. METHOD: One hundred ninety-six AL residents were recruited from 22 (10 large and 12 small) randomly selected AL facilities in the city of Baltimore and seven Maryland counties. Chart review, staff and family history, comprehensive in-person resident evaluation, and the Cornell Scale for Depression in Dementia (CSDD) were administered by an experienced team of geriatric psychiatry clinicians. Those scoring >7 on the CSDD, a cut point repeatedly associated with poor outcomes, were considered clinically depressed. RESULTS: Participants had an average age of 86 years, most were female and widowed, and 68% met consensus criteria for dementia. Twenty-four percent (47 of 196) of the sample was depressed. In bivariate analyses, depression was significantly related to medical comorbidity, need for activities of daily living (ADLs) assistance, more days spent in bed, and less participation in organized activities. After controlling for pertinent covariates in a regression model, only need for ADL assistance remained significantly associated with depression. Forty-three percent of those currently depressed were receiving antidepressants and were more likely to receive them if they lived in a large AL facility. Sixty percent of depressed residents had no regular source of psychiatric care. CONCLUSIONS: In the first clinical study implemented by geriatric psychiatry professionals in AL, depression was found to be common, undertreated, and related to physical burden. AL is a rapidly growing segment of long-term care and represents an important setting in which to find and treat serious depression.

Comparison of three rating scales as outcome measures for treatment trials of depression in Alzheimer disease: findings from DIADS.

CONTEXT: Major depression affects about 25% of patients with Alzheimer's disease (AD) and has serious adverse consequences for patients as well as caregivers. Studies of treatments for depression in AD, like most treatment studies, depend on the ability of the scales used to measure outcome to detect a difference between the effects of treatment and control, particularly in trials conducted over waves. OBJECTIVE: To compare the ability of three depression scales, and some of their subscales, to detect the difference in the effects of drug (treatment) and placebo (control). DESIGN: Comparison of three scales of depression in terms of percent variance explained as indicated by the adjusted or partial eta-squared for the effect of drug versus placebo, controlling for baseline depression, in a randomized, placebo-controlled, parallel, 12-week, clinical trial of sertraline for the treatment of depression with AD. SETTING: University outpatient clinic. PARTICIPANTS: Forty-four patients with probable Alzheimer's disease and Major Depressive Episode. OUTCOME MEASURES: The Cornell Scale for Depression in Dementia (CSDD), the Hamilton Depression Rating Scale (HDRS), and the Neuropsychiatric-Inventory Mood Domains (NPI-M). RESULTS: Examination of the treatment effects as indicated by the partial eta-squared's for each scale at each wave, revealed a slight, but not significant, advantage for the use of the CSDD over the HDRS, and a significant advantage for the use of either of these over the NPI-M. Treatment effects, as reflected in the partial eta-squared's computed for the subscales at each wave, were significant for all four subscales, and were largest for the CSDD 'mood' subscale although they were not significantly greater than for the other subscales. CONCLUSIONS: The CSDD, and particularly its mood subscale, appears to be more sensitive than the HDRS, it's subscales or the NPI-M, for comparing drug to placebo in treating major depression in AD patients. Treatment effects as reflected in the partial eta-squared's were largest on the CSDD mood subscale and increased over time. The pattern for the other subscales was non-monotonic over waves and resembled the pattern for the entire scale. Perhaps combining the CSDD two subscales obscures the treatment effects for the separate subscales.

Correlates of caregiver-rated quality of life in assisted living: the Maryland Assisted Living study.

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.

Transition to nursing home from assisted living is not associated with dementia or dementia-related problem behaviors.

OBJECTIVES: To examine risk factors for transition from assisted living (AL) care to skilled nursing facility (SNF) care in a random sample of adults residing in AL. DESIGN: Baseline clinical evaluation and telephone follow-up at 6-month intervals for up to 36 months. SETTING: AL facilities in central Maryland. PARTICIPANTS: There were 198 participants randomly sampled from AL facilities stratified by facility size. MEASUREMENTS: Consensus diagnoses by multidisciplinary geriatric psychiatry team as well as a broad range of neuropsychiatric and functional scales including Neuropsychiatric Inventory, Cornell Scale for Depression in Dementia, Mini-Mental State Exam, and Alzheimer's Disease Related Quality of Life Scale, as well as cognitive tests. Possible risk factors for transition to SNF were assessed in Cox proportional-hazards multivariate regression methods, using a P value less than .05 for statistical significance. RESULTS: Twenty-nine participants transitioned to SNF care. Mean AL survival time from baseline evaluation was 0.8 (SD 0.6) years for residents transitioned to SNF and 1.4 (SD 0.7) years for residents remaining in AL at follow-up. Risk factors for transition to SNF included declining health, chronic pain, appetite changes, and being widowed, while insomnia was protective against transition to SNF. Surprisingly, dementia and neuropsychiatric symptoms did not increase risk of transition to SNF. CONCLUSION: Survival time in AL is determined by factors similar to those operating on community-dwelling elderly, but dementia and neuropsychiatric symptoms do not alter survival time.

The association of neuropsychiatric symptoms and environment with quality of life in assisted living residents with dementia.

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.
