We describe the prevalence, assessment, and treatment of, as well as characteristics associated with, depression in residential care/assisted living and nursing home residents with dementia. Overall, 25% of the participants were depressed. Depression was related to severe cognitive impairment, behavioral symptoms, pain, and for-profit nursing home residence.
This article describes care for behavioral symptoms related to dementia (BSRD) and identifies their potential correlates among 347 residents with dementia living in 45 assisted living facilities and nursing homes from four states. The prevalence of BSRD was associated with staff training and resident cognition, mood, mobility, and psychotropic use. Attention to staff training and depression management might improve BSRD.
This article describes the prevalence, assessment, and treatment of, as well as characteristics associated with, mobility limitation in 343 residents with dementia in 45 assisted living facilities and nursing homes. Overall, 89% of residents had some degree of mobility limitation. Mobility limitation was associated with fewer behavioral symptoms, low fluid intake, professional assessment, and professional and informal treatment.
This article describes the prevalence, assessment, and treatment of pain, as well as characteristics associated with pain, in 331 residents with dementia in 45 assisted living facilities and nursing homes. Overall, 21% of residents had pain, and pain was more commonly reported in for-profit facilities, and for those receiving professional assessment and treatment.
This article describes the prevalence, assessment, and treatment of, as well as characteristics associated with, the food and fluid intake of 407 residents with dementia in 45 assisted living facilities and nursing homes. Overall, 54% of observed residents had low food intake, and 51% had low fluid intake. Staff monitoring of residents, having meals in a public dining area, and the presence of noninstitutional features were each associated with higher food and fluid intake.
This article describes the characteristics associated with activity involvement in 400 residents with dementia in 45 assisted living facilities and nursing homes. Activity involvement was related to family involvement in care and staff encouragement, after adjusting for resident age, gender, race, cognitive and functional status, and comorbidity.
PURPOSE: The purpose of this study was to compare the sociodemographics, self-rated health, and involvement levels of family caregivers of residents with dementia in residential care/assisted living (RC/AL) versus nursing home settings. DESIGN AND METHODS: We conducted telephone interviews with the family caregivers most involved with 353 residents of 34 residential care and 10 nursing home facilities. We measured involvement by caregiver self-report of monthly out-of-pocket spending, involvement and burden ratings, and the frequency of engaging in eight specific care activities. Open-ended questions elicited areas in which caregivers preferred different involvement and ways the facility could facilitate involvement. RESULTS: Nursing home caregivers rated their health poorer than RC/AL caregivers, but there were no sociodemographic differences between the two. RC/AL caregivers rated both their perception of involvement and burden higher and engaged more frequently in monitoring the resident's health, well-being, and finances than did nursing home caregivers, although the reported time spent per week on care did not differ. IMPLICATIONS: RC/AL and nursing home caregivers to residents with dementia may tailor their care to fit the needs of the resident and setting. Results are discussed in relation to the Congruence Model of Person-Environment Fit.
PURPOSE: Considering the increasing proportion of residents in long-term care who have dementia, and the important influence that direct care providers have on resident quality of life, this study explores the dementia-related attitudes of residential care/assisted living (RC/AL) and nursing home staff, as well as their work stress and satisfaction. DESIGN AND METHODS: Data were derived from interviews with 154 direct care providers from 31 RC/AL facilities and 10 nursing homes who participated in the Collaborative Studies of Long-Term Care. RESULTS: Stress was more often reported by care providers who had been working for 1 to 2 years (compared with longer); in addition, those who had been working for 1 to 2 years were more likely to espouse hopeful or person-centered attitudes than those who had been working for a longer period of time. Also, a person-centered attitude related to satisfaction, and perceived competence in providing dementia care was consistently associated with dementia-sensitive attitudes and job satisfaction. IMPLICATIONS: Attending to the welfare and ongoing training of workers who have demonstrated job commitment may lessen their tendency to become jaded over time or seek job opportunities elsewhere. Further, the attitudes the staff hold related to dementia and the training they receive to provide dementia care are important for their own well-being.
OBJECTIVES: To compare outcomes of infection in nursing home residents with and without early hospital transfer. DESIGN: Observational cohort study. SETTING: Fifty-nine nursing homes in Maryland. PARTICIPANTS: Two thousand one hundred fifty-three individuals admitted to nursing homes between 1992 and 1995. MEASUREMENTS: Incident infection was recorded when a new infectious diagnosis was documented in the medical record or nonprophylactic antibiotic therapy was prescribed. Early hospital transfer was defined as transfer to the emergency department or admission to the hospital within 3 days of infection onset. Infection, resident, and facility characteristics were entered into a multivariate model to create a propensity score for early hospital transfer. Association between early hospital transfer and outcomes of infection, namely pressure ulcers and death between Days 4 and 34 after infection onset, were examined, controlling for propensity score. RESULTS: Four thousand nine hundred ninety infections occurred in 1,301 residents. Genitourinary (28%), skin (19%), upper respiratory (13%), and lower respiratory (12%) were the most common types. Three hundred seventy-five episodes in which residents survived 3 days (7.6%) resulted in early hospital transfer. In multivariate regression, individuals with early hospital transfer had higher mortality (odds ratio (OR) 1.44, 95% confidence interval (CI)=1.04-1.99) and, in 1-month survivors, a greater occurrence of pressure ulcers (OR 1.61, 95% CI=1.17-2.20) than those without, after adjusting for propensity score. CONCLUSION: Using observational data and propensity score methods, outcomes were worse in nursing home residents transferred to the hospital within 3 days of infection onset than in those who remained in the nursing home.
OBJECTIVES: To evaluate the association between dementia and mortality, adverse health events, and discharge disposition of newly admitted nursing home residents. It was hypothesized that residents with dementia would die at a higher rate and develop more adverse health events (e.g., infections, fevers, pressure ulcers, falls) than residents without dementia because of communication and self-care difficulties. DESIGN: An expert clinician panel diagnosed an admission cohort from a stratified random sample of 59 Maryland nursing homes, between 1992 and 1995. The cohort was followed for up to 2 years or until discharge. SETTING: Fifty-nine Maryland nursing homes. PARTICIPANTS: Two thousand one hundred fifty-three newly admitted residents aged 65 and older not having resided in a nursing home for 8 or more days in the previous year. MEASUREMENTS: Mortality, infection, fever, pressure ulcers, fractures, and discharge home. RESULTS: Residents with dementia had significantly lower overall rates of infection (relative risk (RR)=0.77, 95% confidence interval (CI)=0.70-0.85) and mortality (RR=0.61, 95% CI=0.53-0.71) than those without dementia, whereas rates of fever, pressure ulcers, and fractures were similar for the two groups. These results persisted when rates were adjusted for demographic characteristics, comorbid conditions, and functional status. During the first 90 days of the nursing home stay, residents with dementia had significantly lower rates of mortality if not admitted for rehabilitative care under a Medicare qualifying stay (RR=0.25, 95% CI=0.14-0.45), were less often discharged home (RR=0.33, 95% CI=0.28-0.38), and tended to have lower fever rates (RR=0.78, 95% CI=0.63-0.96) than residents without dementia. CONCLUSION: Newly admitted nursing home residents with dementia have a profile of health events that is distinct from that of residents without dementia, indicating that the two groups have different long-term care needs. Results suggest that further investigation of whether residents with dementia can be well managed in alternative residential settings would be valuable.
BACKGROUND: Residential care/assisted living (RC/AL) is a rapidly growing, long-term care setting, where medication use has not been carefully examined. We sought to determine the prevalence and predictors of nonprescribing of selected medications whose value in decreasing morbidity has been established in clinical trials. METHODS: As part of a survey of a stratified random sample of 193 RC/AL facilities in Florida, Maryland, New Jersey, and North Carolina, data were gathered on 2014 residents 65 years and older. Patient characteristics and diagnoses were recorded based on medical record reviews and in-person patient assessments; all medications administered at least 4 of the previous 7 days were recorded. Data on facility characteristics were obtained by interviewing facility administrators. Bivariate and multivariate logistic regression was performed to identify associations between medication nonprescribing and facility characteristics, physician visitation, and patient age, sex, race, comorbidity, functional dependency, and cognition. RESULTS: Of 328 subjects with congestive heart failure, 204 (62.2%) were not receiving an angiotensin-converting enzyme inhibitor; of 172 subjects with prior myocardial infarction, 60.5% were not receiving aspirin and 76.2% were not receiving beta-blockers; of 435 patients with history of stroke, 37.5% were not receiving an anticoagulant or antiplatelet agent; and of 315 patients with osteoporosis, 61.0% were not receiving calcium supplementation and 51.1% were not receiving any treatment for the condition. Resident age, race, sex, comorbidity, cognitive status, and dependency in activities of daily living were rarely associated with nonprescribing; in contrast, facility factors-particularly facility type and the frequency of physician visits-were somewhat more frequently associated with nonprescribing. CONCLUSIONS: Undertreatment appears to be prevalent in RC/AL facilities. Since preserving independence is often a primary goal of care in these settings, more attention may need to be paid to the use of treatments that have been shown to reduce long-term morbidity.
OBJECTIVES: To compare proxy perceptions about change over 6 months in physical, instrumental, affective, and cognitive functioning of older persons with computed change in patient self-report and performance and patient's own perceptions about change. DESIGN: Prospective study. SETTING: Recovery from hip fracture that occurred in community-dwelling persons in Baltimore, Maryland, in 1990-91. The recovery from the sixth to the 12th month postfracture was observed. PARTICIPANTS: One hundred forty-one hip fracture patients aged 65 and older and a self-designated proxy for each. MEASUREMENTS: For specific tasks of physical and instrumental functioning, proxy perception of change over the previous 6 months asked in the 12th month postfracture was compared with change in criterion measures (subject self-report and observed performance) from the sixth to the 12th month postfracture. For global change over the previous 6 months in each area of functioning, proxy perception was compared with the subject's own perception in the 12th month postfracture. RESULTS: Agreement between proxy perceptions of change and change in criterion measures was poor. There was a general pattern for proxies to overstate improvement and understate deterioration in comparison with change observed in criterion measures for specific tasks of physical and instrumental functioning. Proxies' global perceptions reported subjects improving less and deteriorating more than patients' own perceptions. CONCLUSION: Proxy perceptions about task-specific and global changes in subjects' functional health over a short period of time are systematically different from patient report and observed performance.
OBJECTIVES: To compare black and white nursing home residents with respect to the incidence of nursing home (NH)-acquired pressure ulcers (PUs) and to examine the role of resident characteristics and facility characteristics in explaining differences between the racial groups. DESIGN: Prospective cohort study conducted between 1992 and 1995. SETTING: Fifty-nine Maryland NHs. PARTICIPANTS: A total of 1,938 residents (301 black, 1,637 white) aged 65 and older newly admitted to participating NHs. MEASUREMENTS: The outcome variable was the first occurrence of a Stage 2, 3, or 4 PU as determined based on medical record review. The predictor variable was race (black, white). Eight resident characteristics (age, sex, number of activity of daily living dependencies, bedfast, PU on admission to facility, incontinence, dementia, and whether the resident was on Medicaid) and three facility characteristics (number of beds, for-profit ownership status, and urban/nonurban location) were considered as possible confounding variables. RESULTS: The incidence of PUs was 0.38 per person-year in the NH. The rate for blacks was significantly higher than for whites (0.56 vs 0.35 per person-year) (P<.001). In multivariate analysis, controlling for eight resident characteristics and three facility characteristics, race was significantly associated with PU incidence (hazard ratio comparing blacks with whites=1.31, 95% confidence interval=1.02-1.66). CONCLUSION: Blacks have a higher incidence of NH-acquired PUs than whites; resident characteristics appear to mediate the higher risk. Future research should aim to identify modifiable factors that explain differences between racial groups in PU risk and to develop solutions to prevent the suffering and cost associated with PUs.
OBJECTIVES: To examine the prevalence, correlates, and medication management of behavioral symptoms in elderly people living in residential care/assisted living (RC/AL) facilities. DESIGN: Cross-sectional study. SETTINGS: A stratified random sample of 193 RC/AL facilities in four states (Florida, Maryland, New Jersey, North Carolina). PARTICIPANTS: A total of 2,078 RC/AL residents aged 65 and older. MEASUREMENT: Behavioral symptoms were classified using a modified version of the Cohen-Mansfield Agitation Inventory. Additional items on resistance to care were also examined. RESULTS: Approximately one-third (34%) of RC/AL residents exhibited one or more behavioral symptoms at least once a week. Thirteen percent exhibited aggressive behavioral symptoms, 20% demonstrated physically nonaggressive behavioral symptoms, 22% expressed verbal behavioral symptoms, and 13% resisted taking medications or activities of daily living care. Behavioral symptoms were associated with the presence of depression, psychosis, dementia, cognitive impairment, and functional dependency, and these relationships persisted across subtypes of behavioral symptoms. Overall, behavioral symptoms were more prevalent in smaller facilities. More than 50% of RC/AL residents were taking a psychotropic medication, and two-thirds had some mental health problem indicator (dementia, depression, psychosis, or other psychiatric illness). CONCLUSION: Integrating mental health services within the process of care in RC/AL is needed to manage and accommodate the high prevalence of behavioral symptoms in this evolving long-term setting.
Dramatic growth in Assisted Living (AL) has resulted in increasing research and policy interest. This analysis compares smaller and larger AL facilities in four states to determine whether extant measures of four key concepts, used to distinguish the AL sector, give advantage to larger facilities. Quantitative comparisons predominantly show differences favorable to larger facilities; qualitative information raises the prospect that current measures overlook beneficial aspects of smaller facilities. If small facilities are included under the AL banner. both policy provisions and quality assessment must be carefully crafted to avoid placing small homes in funding and oversight jeopardy as AL develops.
BACKGROUND: The contribution of hip fracture to the risk of subsequent fractures is unclear. METHODS: Data from the Baltimore Hip Studies and the Established Populations for Epidemiologic Studies of the Elderly (EPESE) were used. Baltimore subjects enrolled at the time of hip fracture ( n=549) and EPESE subjects without previous fractures at baseline ( n=10,680) were followed for 2-10 years. Self-reported nonhip skeletal fracture was the outcome, and hip fracture was a time-varying covariate in a survival analysis stratified by study site. The model was adjusted for race, sex, age, BMI, stroke, cancer, difficulty walking across a room, dependence in grooming, dependence in transferring, and cognitive impairment. RESULTS: The rate of all subsequent self-reported fractures after hip fracture was 10.4 fractures/100 person-years. The unadjusted hazard of nonhip skeletal fracture was 2.52 (95% confidence interval 2.05 to 3.12) for subjects with hip fracture compared with subjects without; when adjusted for other known fracture risk factors the hazard ratio was 1.62 (1.30 to 2.02). Men and women had a similar relative risk increase. The increased risk of secondary fracture after hip fracture persisted over time. CONCLUSIONS: A hip fracture is associated with a 2.5-fold increased risk of subsequent fracture, which is not entirely explained by prefracture risk factors. Careful attention to secondary prevention is warranted in these patients.
Disability attributable to hip fracture regarding activities of daily living was evaluated by comparing 594 hip fracture patients entering eight hospitals in Baltimore, Maryland, in 1990-1991 with community-dwelling aged from the Established Populations for Epidemiologic Studies of the Elderly (EPESE) cohort matched on age, sex, and walking ability. Subjects were assessed at baseline (prefracture report for patients), 12 months, and 24 months. At baseline, 26% of both groups had walking disability, 12-14% had transferring disability, and 6-8% evidenced grooming disability. At 12 and 24 months, about 50% of hip fracture patients were walking disabled compared with 21-29% of EPESE respondents after the authors controlled for age, sex, comorbidities, and functional status (excess disability attributable to hip fracture, i.e., attributable disability, of 26 additional cases of disability per 100 persons in the hip fracture cohort during follow-up). Likewise, hip fracture patients experienced more disability regarding transferring (38-39% vs. 10-18%; attributable disability, approximately 22 cases per 100 persons) and grooming (17-19% vs. 7-15%; attributable disability, approximately six cases per 100 persons). Thus, results showed that hip fracture patients had substantially more activities of daily living disability than that explained by aging over 24 months.
OBJECTIVES: To compare rates of falling between nursing home residents with and without dementia and to examine dementia as an independent risk factor for falls and fall injuries. DESIGN: Prospective cohort study with 2 years of follow-up. SETTING: Fifty-nine randomly selected nursing homes in Maryland, stratified by geographic region and facility size. PARTICIPANTS: Two thousand fifteen newly admitted residents aged 65 and older. MEASUREMENTS: During 2 years after nursing home admission, fall data were collected from nursing home charts and hospital discharge summaries. RESULTS: The unadjusted fall rate for residents in the nursing home with dementia was 4.05 per year, compared with 2.33 falls per year for residents without dementia (P<.0001). The effect of dementia on the rate of falling persisted when known risk factors were taken into account. Among fall events, those occurring to residents with dementia were no more likely to result in injury than falls of residents without dementia, but, given the markedly higher rates of falling by residents with dementia, their rate of injurious falls was higher than for residents without dementia. CONCLUSION: Dementia is an independent risk factor for falling. Although most falls do not result in injury, the fact that residents with dementia fall more often than their counterparts without dementia leaves them with a higher overall risk of sustaining injurious falls over time. Nursing home residents with dementia should be considered important candidates for fall-prevention and fall-injury-prevention strategies.
