Characteristics Associated With Depression in Long-Term Care Residents With Dementia

Concordance of self- and informant-rated depressive symptoms in nursing home residents with Dementia: cross-sectional findings

BACKGROUND

Depression is highly prevalent in nursing home residents living with moderate to severe dementia. However, assessing depressive symptoms in residents with dementia can be challenging and may vary by rater perspective. We aimed to investigate the concordance of, and factors associated with self- and informant-rated depressive symptoms in nursing home residents with dementia.

METHODS

Cross-sectional data was collected from N = 162 nursing home residents with dementia (age: 53-100; 74% women). Self-ratings were assessed with the Geriatric Depression Scale, while the depression and anxiety items of the Neuropsychiatric Inventory were used for informant-ratings. Cohen's Kappa was calculated to determine the concordance of both measures and of each with antidepressant medication. Multivariate associations with sociodemographic variables, self- and informant-rated quality of life, dementia stage, neuropsychiatric symptoms, functional status and antidepressant medication were analysed with linear mixed models and generalized estimating equations.

RESULTS

Concordance between self- and single item informant-rated depressive symptoms was minimal (Cohen's Kappa = .22, p = .02). No concordance was found for self-reported depressive symptoms and the combined informant-rated depression-anxiety score. Self-reported depression was negatively associated with self-rated quality of life (β = -.32; 95%CI: -.45 to -.19, p < .001), informant-rated quality of life (β = -.25; 95%CI: -.43 to -.07, p = .005) and functional status (β = -.16; 95%CI: -.32 to -.01, p = .04), whilst single item informant-rated depression revealed negative associations with informant-rated quality of life (β = -.32; 95%CI: -.52 to -.13, p = .001) and dementia stage (β = -.31; 95%CI: -.52 to -.10, p = .004). The combined informant-rated depression-anxiety score showed negative associations with self-rated quality of life (β = -.12; 95%CI: -.22 to -.03, p = .01) and dementia stage (β = -.37; 95%CI: -.67 to -.07, p = .02) and a positive association with neuropsychiatric symptoms (β = .30; 95%CI: .10 to .51, p = .004). No concordance was found with antidepressant medication.

CONCLUSIONS

In line with our expectations, low agreement and unique association patterns were found for both measures. These findings indicate that both instruments address different aspects of depression und underline the need for comprehensive approaches when it comes to detecting signs of clinically relevant depressive symptoms in dementia.

TRIAL REGISTRATION

The trial was registered with the ISRCTN registry (Trial registration number: ISRCTN98947160 ).

Primary Palliative Care in Dementia

Primary palliative care is a fundamental aspect of high-quality care for patients with a serious illness such as dementia. The clinician caring for a patient and family suffering with dementia can provide primary palliative care in numerous ways. Perhaps the most important aspects are high quality communication while sharing a diagnosis, counseling the patient through progression of illness and prognostication, and referral to hospice when appropriate. COVID-19 presents additional risks of intensive care requirement and mortality which we must help patients and families navigate. Throughout all of these discussions, the astute clinician must monitor the patient's decision making capacity and balance respect for autonomy with protection against uninformed consent. Excellent primary palliative care also involves discussion of deprescribing medications of uncertain benefit such as long term use of cholinesterase inhibitors and memantine and being vigilant in the monitoring of pain with its relationship to behavioral disturbance in patients with dementia. Clinicians should follow a standardized approach to pain management in this vulnerable population. Caregiver burden is high for patients with dementia and comprehensive care should also address this burden and implement reduction strategies. When these aspects of care are particularly complex or initial managements strategies fall short, palliative care specialists can be an important additional resource not only for the patient and family, but for the care team struggling to guide the way through a disease with innumerable challenges.

Dyadic interactions and physical and social environment in dementia mealtime care: a systematic review of instruments

Using valid instruments to measure dyadic interactions and physical and social environment during mealtime care of persons with dementia is critical to evaluate the process, fidelity, and impact of mealtime interventions. However, the characteristics and quality of existing instruments remain unexplored. This systematic review described the characteristics and synthesized the psychometric quality of instruments originally developed or later modified to measure mealtime dyadic interactions and physical and/or social dining environment for people with dementia, on the basis of published reports between January 1, 1980 and December 31, 2020. We identified 26 instruments: 17 assessed dyadic interactions, one assessed physical environment, and eight assessed physical and social environment. All instruments were used in research and none in clinical practice. All instruments were observational tools and scored as having low psychometric quality, except for the refined Cue Utilization and Engagement in Dementia (CUED) mealtime video-coding scheme rated as having moderate quality. Reasons for low quality are the use of small samples compared with the number of items, limited psychometric testing, and inadequate estimates. All existing tools warrant further testing in larger diverse samples in varied settings and validation for use in clinical practice. The refined CUED is a potential tool for use and requires testing in direct on-site observations.

Care home residents’ quality of life and its association with CQC ratings and workforce issues: the MiCareHQ mixed-methods study

Background

Care home staff have a critical bearing on quality. The staff employed, the training they receive and how well they identify and manage residents’ needs are likely to influence outcomes. The Care Act 2014 (Great Britain. The Care Act 2014. London: The Stationery Office; 2014) requires services to improve ‘well-being’, but many residents cannot self-report and are at risk of exclusion from giving their views. The Adult Social Care Outcomes Toolkit enables social care-related quality of life to be measured using a mixed-methods approach. There is currently no equivalent way of measuring aspects of residents’ health-related quality of life. We developed new tools for measuring pain, anxiety and depression using a mixed-methods approach. We also explored the relationship between care home quality, residents’ outcomes, and the skill mix and employment conditions of the workforce who support them.

Objectives

The objectives were to develop and test measures of pain, anxiety and depression for residents unable to self-report; to assess the extent to which regulator quality ratings reflect residents’ care-related quality of life; and to assess the relationship between aspects of the staffing of care homes and the quality of care homes.

Design

This was a mixed-methods study.

Setting

The setting was care homes for older adults in England.

Participants

Care home residents participated.

Results

Three measures of pain, anxiety and low mood were developed and tested, using a mixed-methods approach, with 182 care home residents in 20 care homes (nursing and residential). Psychometric testing found that the measures had good construct validity. The mixed-methods approach was both feasible and necessary with this population, as the majority of residents could not self-report. Using a combined data set (n = 475 residents in 54 homes) from this study and the Measuring Outcomes in Care Homes study (Towers AM, Palmer S, Smith N, Collins G, Allan S. A cross-sectional study exploring the relationship between regulator quality ratings and care home residents’ quality of life in England. Health Qual Life Outcomes 2019;17:22) we found a significant positive association between residents’ social care-related quality of life and regulator (i.e. Care Quality Commission) quality ratings. Multivariate regression revealed that homes rated ‘good/outstanding’ are associated with a 12% improvement in mean current social care-related quality of life among residents who have higher levels of dependency. Secondary data analysis of a large, national sample of care homes over time assessed the impact of staffing and employment conditions on Care Quality Commission quality ratings. Higher wages and a higher prevalence of training in both dementia and dignity-/person-centred care were positively associated with care quality, whereas high staff turnover and job vacancy rates had a significant negative association. A 10% increase in the average care worker wage increased the likelihood of a ‘good/outstanding’ rating by 7%.

Limitations

No care homes rated as inadequate were recruited to the study.

Conclusions

The most dependent residents gain the most from homes rated ‘good/outstanding’. However, measuring the needs and outcomes of these residents is challenging, as many cannot self-report. A mixed-methods approach can reduce methodological exclusion and an over-reliance on proxies. Improving working conditions and reducing staff turnover may be associated with better outcomes for residents.

Future work

Further work is required to explore the relationship between pain, anxiety and low mood and other indicators of care homes quality and to examine the relationship between wages, training and social care outcomes.

Vocally disruptive behaviour in nursing home residents in Ireland: a descriptive study

BACKGROUND

Vocally disruptive behaviour (VDB) is relatively common in nursing home residents but difficult to treat. There is limited study on prevalence and treatment of VDB. We hypothesise that VDB is a result of complex interaction between patient factors and environmental contributors.

METHODS

Residents of nursing homes in south Dublin were the target population for this study. Inclusion criteria were that the residents were 65 years or over and exhibited VDB significant enough for consideration in the resident's care plan. Information on typology and frequency of VDB, Interventions employed and their efficacy, diagnoses, Cohen-Mansfield Agitation Inventory scores, Mini-Mental State Examination scores, and Barthel Index scores were obtained.

RESULTS

Eight percent of nursing home residents were reported to display VDB, most commonly screaming (in 39.4% of vocally disruptive residents). VDB was associated with physical agitation and dementia; together, these two factors accounted for almost two-thirds of the variation in VDB between residents. One-to-one attention, engaging in conversation, redirecting behaviour, and use of psychotropic medication were reported by nurses as the most useful interventions. Analgesics were the medications most commonly used (65.7%) followed by quetiapine (62.9%), and these were reportedly effective in 82.6% and 77.2% of residents respectively.

CONCLUSIONS

VDB is common, challenging, and difficult to manage. The study of VDB is limited by a variety of factors that both contribute to this behaviour and make its treatment challenging. Issues relating to capacity and ethics make it difficult to conduct randomised controlled trials of treatments for VDB in the population affected.

Hungry for more: Low resident social engagement is indirectly associated with poor energy intake and mealtime experience in long-term care homes

Mealtimes in long-term care (LTC) homes provide social engagement and nutritional intake to residents. Psychosocial challenges may detract from the mealtime experience, resulting in low food intake and increased risk of malnutrition. This study explores the independent effects of psychosocial factors on energy intake among LTC residents. Secondary data (Making the Most of Mealtimes [M3]) from residents in 32 Canadian LTC homes were analyzed. Data included 3-day weighed food intake, mealtime care actions taken by staff, loss of appetite, eating challenges, and other resident characteristics. Psychosocial factors (i.e., social engagement, depression, and aggressive behaviours) were measured using standardized scales. The independent effects of psychosocial factors on energy intake were tested using bivariate and linear regression analyses adjusted for loss of appetite, eating challenges, and demographic characteristics. The final sample included 604 residents (mean age = 86.8 ± 7.8 years; 31.8% male). Of the three psychosocial factors, only social engagement was associated with energy intake. Low social engagement was associated with cognitive and functional challenges, malnutrition risk, more task-focused mealtime actions by staff, and lower energy intake. Simple regression analysis revealed that individuals with low social engagement ate 59.6 kcal less per day (95% CI = -111.2, -8.0). This significant association remained when adjusting for loss of appetite, but was no longer significant when adjusting for eating challenges. Low social engagement occurs concurrently with physical and functional challenges among LTC residents, affecting both the nutritional and social aspects of mealtimes. Emphasis on socializing during mealtimes, especially for those with eating challenges (e.g., requiring assistance), may contribute to improved resident appetite and quality of life.

Patient and caregiver outcomes at the integrated memory care clinic

The purpose of this longitudinal cohort study was to explore the outcomes of persons living with dementia (PLWD) and their caregivers during their first 9 months at the Integrated Memory Care Clinic (IMCC). IMCC advanced practice registered nurses provide dementia care and primary care simultaneously and continuously to PLWD until institutionalization. Changes were examined in caregivers' psychological well-being (perceived stress, depressive symptoms, caregiver burden, and anxiety) and health status and in PLWDs' quality of life and neuropsychiatric symptoms. Data were collected at baseline, then 3 and 6 months post-baseline. Forty-two caregivers completed all 3 assessments. Most variables remained unchanged. Statistically significant improvements in 5 sub-scales of the Neuropsychiatric Inventory were observed: caregivers' distress regarding their PLWDs' delusions and anxiety, and PLWDs' severity of delusions, depression, and total symptom severity. Further testing of the IMCC is required, including in quasi-experimental studies, to determine its efficacy.

The prevalence, reporting, and treatment of anxiety among older adults in nursing homes and other residential aged care facilities

BACKGROUND

Little is known about anxiety in aged care populations, despite its increase in this frail population. This study investigated the prevalence, recording, and treatment rate of anxiety disorders among aged care residents.

METHODS

A cross-sectional, observational design was used to assess 180 elderly residents from 12 aged care facilities in Melbourne, Australia. Participants were assessed for threshold and subthreshold anxiety disorders and comorbid depression using the MINI for DSM-5. Medical files were also reviewed to determine whether there was any indication that anxiety had previously been detected, and what treatment those with a threshold/subthreshold diagnosis were receiving.

RESULTS

Overall prevalence of threshold and subthreshold anxiety disorders was 19.4% and 11.7%, respectively. Generalized anxiety disorder was the most common threshold disorder and agoraphobia was the most prevalent subthreshold anxiety disorder. While less than half of those with a threshold or subthreshold anxiety disorder had an indication of anxiety in their file, the majority received psychotropic medication. Cognitive impairment was not significantly associated with the prevalence or treatment of anxiety.

CONCLUSIONS

The prevalence of threshold and subthreshold anxiety in aged care settings is high, but remains under-reported by staff and GPs. Facility staff and GPs should ensure they are aware of how anxiety presents in elderly residents and routinely screen for this common mental health issue. This cohort had poor access to psychological treatments for their condition.

Dysphoric symptoms in relation to other behavioral and psychological symptoms of dementia, among elderly in nursing homes

Background

Behavioral and psychological symptoms of dementia (BPSD) are common and varied in the elderly. The aim of the current study was to explore associations between BPSD and dysphoric symptoms at different levels of cognitive impairment.

Methods

Assessments of 4397 elderly individuals living in nursing homes in Sweden were performed. Data on cognitive function and BPSD were collected using the Multi-Dimensional Dementia Assessment Scale (MDDAS). The relationships between dysphoria and eight BPSD factors were plotted against cognitive function to investigate how dysphoria affects BPSD throughout the dementia disease.

Results

Overall, dysphoric symptoms were most prevalent in persons with moderate cognitive impairment. However, moderate to severe dysphoric symptoms showed no clear variation with cognitive impairment. Furthermore, aggressive behavior, verbally disruptive/attention-seeking behavior, hallucinatory symptoms and wandering behavior were more common with concurrent dysphoria regardless of cognitive function. In contrast, passiveness was more common with concurrent dysphoria in mild cognitive impairment but not in moderate to severe cognitive impairment.

Conclusions

BPSD, including aggressive behavior and hallucinations, were more common with concurrent dysphoric symptoms, providing insight into behavioral and psychological symptoms among individuals with cognitive impairment. Apathy was more commonly associated with concurrent dysphoria at early stages of cognitive decline but not at later stages, indicating that apathy and dysphoria represent separate syndromes among elderly patients with moderate to severe cognitive impairment.

Associations between pain and depression in nursing home patients at different stages of dementia

BACKGROUND

Pain is associated with depression in nursing home patients with dementia. It is, however, unclear whether pain increases depression. Therefore we evaluated the prospective associations between pain and depressive symptoms in nursing home patients at different stages of cognitive impairment.

METHODS

Two longitudinal studies were combined, including 931 patients (≥65 years) from 65 nursing homes. One study assessed patients at admission, with 6-month follow-up (2012-2014). The other study assessed residents with varying lengths of stay, with 4-month follow-up (2014-2015). Patients were assessed with the Mini-Mental State Examination, the Mobilisation-Observation-Behaviour-Intensity-Dementia-2 Pain Scale, and the Cornell Scale for Depression in Dementia.

RESULTS

At baseline, 343 patients (40% of 858 assessed) had moderate to severe pain, and 347 (38% of 924) had depression. Pain increased the risk of depression (OR 2.35, 95% CI 1.76-3.12). Using mixed model analyses, we found that a 1-point increase in pain was associated with a .48 increase in depression (p<.001). This association persisted in mild, moderate, and severe cognitive impairment. In those recently admitted, depressive symptoms decreased over time, and having less pain at follow-up was associated with a decrease in depressive symptoms (within-subject effect; p=.042).

LIMITATIONS

The two cohorts had different inclusion criteria, which may reduce generalisability. The study design does not allow conclusions on causality.

CONCLUSIONS

Pain and depressive symptoms are associated in patients with dementia. Because reduced pain is associated with less depressive symptoms, these patients should be assessed regularly for untreated pain. The benefit of analgesic treatment should be weighed carefully against the potential for adverse effects.

Huntington's Disease: Prevalence and Psychological Indicators of Pain

Background

Huntington's disease (HD) is a genetic neurodegenerative condition that involves impairments in movement, cognition, and mood. Research is lacking in HD with regard to the prevalence of pain and the relationships between psychological factors and pain. The aim of this research was to investigate the prevalence of pain and identify the psychological factors associated with pain severity in people with HD.

Methods

This data-mining study used data from 1474 people who participated in the European Huntington's Disease Network (EHDN) REGISTRY study. Pain severity was measured using the Medical Outcome Study 36-item short-form health survey. Separate ordinal regression analyses were conducted with participant-rated and interviewer-rated psychological measures (the Hospital Anxiety and Depression Scale-Snaith Irritability Scale and the Unified Huntington's Disease Rating Scale). The psychological factors considered were anxiety, depression, irritability, aggression, low self-esteem, and apathy.

Results

The prevalence of pain in the total sample was 41% (stage I, 42%; stage II, 44%; stage III, 39%; stages IV and V, 50%). After controlling for confounding variables, pain severity was significantly associated with participant-rated anxiety and depression. Interviewer-rated anxiety, depression, and irritability also were significantly associated with severity of pain after controlling for confounding variables.

Conclusions

This research confirmed that pain is indeed an issue for people with HD, particularly during the later stages of the disease. Caregivers and health professionals should consider the possibility that people with HD might be experiencing pain, particularly if they are showing signs of anxiety, depression, or irritability.

Depressive symptomatology and associated factors in dementia in Europe: home care versus long-term care

BACKGROUND

This study forms part of a larger European programme investigating the transition from home care to long-term care (LTC) facility in people with dementia (PwD) at the margins of LTC. The aim of this study was to explore the factors associated with depressive symptomatology in PwD in different settings.

METHODS

A total of 1,538 PwD, of which 957 received home care and 581 lived in a LTC facility, and their carers were interviewed. The Cornell Scale for Depression in Dementia (CSDD) measured depressive symptomatology. PwD completed measures of cognition and quality of life (QoL), and informal or formal carers completed measures on the PwD' QoL, neuropsychiatric behavior, activities of daily living, comorbidities, pain, and falls. Logistic regression was used to assess which factors contributed to depressive symptomatology in the two settings.

RESULTS

Those receiving home care, living in Germany, and with severe dementia, showed the highest prevalence of depressive symptomatology. In the home care group, high levels of pain, neuropsychiatric behavior, and comorbidity, as well as low self- and proxy-rated QoL were factors associated with depressive symptomatology. In the LTC group, low proxy-rated QoL, more severe neuropsychiatric behavior, being a male informal carer and living in Germany were associated with depressive symptomatology.

CONCLUSIONS

Evidence highlights the need for targeting different aspects in the management of depression in dementia, including offering improved pain management for those living in the community. Further research needs to explore cultural variations and carer gender factors associated with higher levels of depressive symptomatology.

Correlates of pain intensity in community-dwelling individuals with mild to moderate dementia

OBJECTIVES

To identify correlates of participant-reported pain in community-dwelling individuals with mild to moderate dementia.

METHODOLOGY

Associations among participant-reported pain intensity and depressive symptoms, mental health diagnoses, pain diagnoses, pain medications, level of functional ability, and cognitive impairment were assessed in 136 community-dwelling veterans with mild to moderate dementia and pain. Univariate and multiple regressions were used to assess relationships among the independent variables and participant-reported pain.

RESULTS

Pain diagnoses (β = .23, t 132 = 2.65, P < .01) and pain medications (β = .21, t 132 = 2.48, P < .05) were correlated with participant-reported pain intensity in univariate regression models. Only pain diagnoses (β = .20, t 132 = 2.17, P < .05) remained a significant predictor in adjusted models.

CONCLUSION

Participant-reported pain in individuals with dementia appears to be a unique construct for which other psychosocial indicators cannot be substituted. Therefore, directly asking community-dwelling individuals with mild to moderate dementia about their pain is a critical component of assessment.

Evaluation of a pet-assisted living intervention for improving functional status in assisted living residents with mild to moderate cognitive impairment: a pilot study

BACKGROUND

In older adults with cognitive impairment (CI), decreased functional status and increased behavioral symptoms require relocation from assisted living (AL) to nursing homes. Studies support positive effects of pets on health/function.

PURPOSE

Evaluate the effectiveness of the Pet AL (PAL) intervention to support physical, behavioral, and emotional function in AL residents with CI.

METHODS

Cognitively impaired AL residents randomized to 60-90 minute sessions [PAL (n = 22) or reminiscing (n = 18)] twice/week for 12 weeks. PAL interventionist encourages residents to perform skills with the visiting dog; reminiscing interventionist encourages residents to reminisce. Monthly assessment of physical (energy expenditure, activities of daily living), emotional (depression, apathy), and behavioral (agitation) function.

RESULTS

In linear mixed models, physical activity depressive symptoms improved more with PAL.

CONCLUSION

Evidence supports that the PAL program helps preserve/enhance function of AL residents with CI. Additional study is required to evaluate the duration and predictors of effectiveness of the PAL intervention.

Stress and Spirituality on the Depressive Symptoms of Older Adults in Assisted Living: Gender Differences

In this study the authors explore the effects of stress and spirituality on the depressive symptoms of 92 older adult men and 224 older adult women who reside in assisted living facilities. Hierarchical regression reveals that stress was related to increases in depressive symptoms. The stress of women was more strongly associated with depressive symptoms than found among men. In contrast, spiritual coping was associated with a decrease in depressive symptoms among all older adults in assisted living. The spiritual coping of older adult women was not a significant predictor of decreased depressive symptoms. Through this study the authors support the use of spiritual interventions to alleviate depressive symptoms experienced by older adults in assisted living.

Association between pain, neuropsychiatric symptoms, and physical function in dementia: a systematic review and meta-analysis

Background

Pain, neuropsychiatric symptoms (NPS) and functional impairment are prevalent in patients with dementia and pain is hypothesized to be causal in both neuropsychiatric symptoms (NPS) and functional impairment. As the exact nature of the associations is unknown, this review examines the strength of associations between pain and NPS, and pain and physical function in patients with dementia. Special attention is paid to the description of measurement instruments and the methods used to detect pain, NPS and physical function.

Methods

A systematic search was made in the databases of PubMed (Medline), Embase, Cochrane, Cinahl, PsychINFO, and Web of Science. Studies were included that described associations between pain and NPS and/or physical function in patients with moderate to severe dementia.

Results

The search yielded 22 articles describing 18 studies, including two longitudinal studies. Most evidence was found for the association between pain and depression, followed by the association between pain and agitation/aggression. The longitudinal studies reported no direct effects between pain and NPS but some indirect effects, e.g. pain through depression. Although some association was established between pain and NPS, and pain and physical function, the strength of associations was relatively weak. Interestingly, only three studies used an observer rating scale for pain-related behaviour.

Conclusions

Available evidence does not support strong associations between pain, NPS and physical function. This might be due to inadequate use or lack of rating scales to detect pain-related behaviour. These results show that the relationship between pain and NPS, as well as with physical function, is complicated and warrants additional longitudinal evaluation.

The course of depressive symptoms as measured by the Cornell scale for depression in dementia over 74 months in 1158 nursing home residents

BACKGROUND

Depressive symptoms and depression are common in nursing home residents. However, longitudinal studies of depression in nursing home residents are scarce and the sample sizes are small. This study aimed to investigate the course of depressive symptoms as measured by the Cornell Scale for Depression in Dementia (CSDD) and associated explanatory demographic and clinical variables.

METHODS

A longitudinal study over 74 months of 1158 nursing home residents aged 50 years and older from twenty six nursing homes in Norway where data was collected at five time points.

RESULTS

"Irritability" was the most prevalent, incident and persistent CSDD symptom. Compared with the baseline assessment, the likelihood of the mood symptoms "suicidal ideation," "pessimism" and "delusions" being present was lower at all subsequent assessments. This persisted after adjusting for the severity of dementia. The severity of depression as measured by CSDD decreased over 74 months when adjusting for relevant resident variables. Poorer physical health, higher number of medications, more severe dementia and use of antidepressants were associated with higher depression score.

LIMITATIONS

Depression and dementia were not diagnosed according to standardized diagnostic criteria. The use of CSDD did not include a clinician׳s interview with the patient. This could have implications for the generalization of the results.

CONCLUSION

This study adds important knowledge about the long-term course of depressive symptoms and depression for residents in nursing homes, and underlines the importance to pay close attention to the overlap between depression and dementia symptoms when evaluating depression in this setting.

Depressive symptoms are associated with analgesic use in people with Alzheimer's disease: Kuopio ALSOVA study

Neuropsychiatric symptoms of Alzheimer's disease (AD) such as depression may be associated with pain, which according to the literature may be inadequately recognized and managed in this population. This study aimed to identify the factors associated with analgesic use in persons with AD; in particular, how AD severity, functional status, neuropsychiatric symptoms of AD, co-morbidities and somatic symptoms are associated with analgesic use. 236 community-dwelling persons with very mild or mild AD at baseline, and their caregivers, were interviewed over five years as part of the prospective ALSOVA study. Generalized Estimating Equations (GEEs) were used to estimate unadjusted and adjusted odds ratios (ORs) for the factors associated with analgesic use over a five year follow-up. The proportion of persons with AD using any analgesic was low (13.6%) at baseline and remained relatively constant during the follow-up (15.3% at Year 5). Over time, the most prevalent analgesic changed from non-steroidal anti-inflammatories (8.1% of persons with AD at Year 1) to acetaminophen (11.1% at Year 5). Depressive symptoms (measured by the Beck Depression Inventory, BDI) were independently associated with analgesic use, after effects of age, gender, education, AD severity, comorbidities and somatic symptoms were taken into account. For every one unit increase in BDI, the odds of analgesic use increased by 4% (OR = 1.04, 95% confidence interval CI = 1.02-1.07). Caregiver depressive symptoms were not statistically significantly associated with analgesic use of the person with AD. Depressive symptoms were significantly associated with analgesic use during the five year follow-up period. Possible explanations warranting investigation are that persons with AD may express depressive symptoms as painful somatic complaints, or untreated pain may cause depressive symptoms. Greater awareness of the association between depressive symptoms and analgesic use may lead to safer and more effective prescribing for these conditions.

Cognitive and affective assessment in day care versus institutionalized elderly patients: a 1-year longitudinal study

Purpose

Cognitive decline and depression are two common mental health problems that may create a need for long-term care among the elderly. In the last decade, the percentage of older adults who receive health care in nursing homes, day care centers, or home support services has increased in Europe. The objectives of this descriptive and nonrandomized longitudinal study were to evaluate and to compare the cognitive and affective evolution of day care versus institutionalized older patients through a 1-year period, and to assess the presence of cognitive and affective impairment as a function of the care setting.

Patients and methods

Ninety-four patients were assessed at baseline, and 63 (67.0%) were reassessed 1 year later. Neuropsychological assessment included measures of cognitive performance (general cognitive status, visuospatial, and language abilities) and affective status (depressive symptoms).

Results

Our findings indicated that the majority of the participants (day care and institutionalized patients) had mild–moderate cognitive impairment at baseline, which significantly increased in both groups after 1-year follow-up. However, the rate of change in global cognitive function did not significantly differ between groups over time. Regarding language abilities, naming function maintained among day care patients in comparison with institutionalized patients, who showed worse performance at follow-up. As regards to affective status, results revealed that institutionalized patients had a significant reduction in depressive symptoms at follow-up, when compared to day care patients. Results also highlight the high frequency of cognitive impairment and depressive symptoms regardless of the care setting.

Conclusion

Our findings revealed a similar global cognitive decline rate between patients receiving day care services and those residing in a nursing home at the 1-year follow-up, and slightly different trajectories in other outcomes such as naming function and depressive symptoms.

Validation of a causal model of agitation among institutionalized residents with dementia in Taiwan

The aim of this study was to test a causal model of the predictors of agitation among 405 nursing home residents in Taiwan with varying degrees of cognitive impairment. Chart review and behavioral observations were used to assess residents' physical and psychosocial condition. The final version of the model had a good fit. Cognitive function and depression had direct effects on agitation, and pain and functional ability had indirect effects on agitation via depression. Additionally, cognitive function and pain influenced functional ability directly, which in turn influenced depression and ultimately influenced agitation. The results suggest that effective management of agitation in demented residents requires identifying the needs underlying the behavior rather than directly treating the behavior itself.

Cornell scale for depression in dementia: study of residents in a northern thai long-term care home

OBJECTIVE

This study aimed to analyse the validity of the Thai version of the Cornell Scale for Depression in Dementia (CSDD) when using DSM-IV criteria.

METHODS

A cross-sectional study was carried out of 84 elderly residents in a residential care home setting in Thailand. The participants went through a comprehensive geriatric assessment which included a Mini-Mental State Examination, a Mini-International Neuropsychiatric Interview (MINI) and use of the CSDD tool. A ROC analysis was performed in order to test the validity of the CSDD as against the DSM-IV when used by the MINI.

RESULTS

ROC analysis revealed a better score for those areas found under the curve for the CSDD-as against the DSM-IV criteria (0.96). With a cut-off score of >6, the CSDD yielded the highest sensitivity score (100%), plus produced a specificity of 81% and a negative predictive value of 100%. It also had a positive predictive value of 69%. The validity of the CSDD was found to be better for the group experiencing cognitive impairment than with the non-cognitive impairment group in terms of the agreement of CSDD items between patients and caregivers. The CSDD yielded a high internal consistency (Cronbach's alpha=0.87).

CONCLUSION

CSDD is a valid tool to use for identifying depressive disorders among Thai LTC home residents - those experiencing and those not experiencing cognitive impairment.

Pain management in patients with dementia

There are an estimated 35 million people with dementia across the world, of whom 50% experience regular pain. Despite this, current assessment and treatment of pain in this patient group are inadequate. In addition to the discomfort and distress caused by pain, it is frequently the underlying cause of behavioral symptoms, which can lead to inappropriate treatment with antipsychotic medications. Pain also contributes to further complications in treatment and care. This review explores four key perspectives of pain management in dementia and makes recommendations for practice and research. The first perspective discussed is the considerable uncertainty within the literature on the impact of dementia neuropathology on pain perception and processing in Alzheimer's disease and other dementias, where white matter lesions and brain atrophy appear to influence the neurobiology of pain. The second perspective considers the assessment of pain in dementia. This is challenging, particularly because of the limited capacity of self-report by these individuals, which means that assessment relies in large part on observational methods. A number of tools are available but the psychometric quality and clinical utility of these are uncertain. The evidence for efficient treatment (the third perspective) with analgesics is also limited, with few statistically well-powered trials. The most promising evidence supports the use of stepped treatment approaches, and indicates the benefit of pain and behavioral interventions on both these important symptoms. The fourth perspective debates further difficulties in pain management due to the lack of sufficient training and education for health care professionals at all levels, where evidence-based guidance is urgently needed. To address the current inadequate management of pain in dementia, a comprehensive approach is needed. This would include an accurate, validated assessment tool that is sensitive to different types of pain and therapeutic effects, supported by better training and support for care staff across all settings.

Comparing families and staff in nursing homes and assisted living: implications for social work practice

Nursing homes and residential care/assisted living settings provide care to 2.4 million individuals. Few studies compare the experience of, and relationships between, family and staff in these settings, despite ongoing family involvement and evidence that relationships are problematic. Data from 488 families and 397 staff members in 24 settings examined family involvement and family and staff burden, depressive symptoms, and perceptions; and staff absenteeism and turnover. There were few differences across setting types. Although conflict rarely occurred, there was room for improvement in family-staff relations; this area, and preparing family for their caregiving roles, are appropriate targets for social work intervention.

Correlates of agitation and depression in nursing home residents with dementia

BACKGROUND

The purpose of this study was to investigate the relationship between dementia severity, age, gender, and prescription of psychotropics, and syndromes of agitation and depression in a sample of nursing home residents with dementia.

METHODS

The Cohen-Mansfield Agitation Inventory (CMAI) was administered to residents with dementia (N = 304) of 18 nursing homes. Agitation symptoms were clustered using factorial analysis. Depression was estimated using the Dementia Mood Assessment Scale (DMAS). Dementia severity was assessed categorically using predefined cut-off scores derived from the Mini-Mental State Examination (MMSE). The relationship between agitation and its sub-syndromes, depression, and dementia severity was calculated using χ 2-statistics. Linear regression analyses were used to calculate the effect of dementia severity and psychotropic prescriptions on agitation and depression, controlling for age and gender.

RESULTS

Increasing stages of dementia severity were associated with higher risk for physically aggressive (p < 0.001) and non-aggressive (p < 0.01) behaviors, verbally agitated behavior (p < 0.05), and depression (p < 0.001). Depressive symptoms were associated with physically aggressive (p < 0.001) and verbally agitated (p < 0.05) behaviors, beyond the effects of dementia severity. Prescription of antipsychotics was correlated with depression and all agitation sub-syndromes except hiding and hoarding.

CONCLUSIONS

Dementia severity is a predictor for agitation and depression. Beyond that, depression increased with dementia severity, and the severity of depression was associated with both physically and verbally aggressive behaviors, indicating that, in advanced stages of dementia, depression in some patients might underlie aggressive behavior.

Comparative validation of proxy-based Montgomery-Åsberg depression rating scale and cornell scale for depression in dementia in nursing home residents with dementia

OBJECTIVE

To 1) compare the accuracy of the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Cornell Scale for Depression in Dementia (CSDD) in nursing home residents with dementia when professional caregivers are the only available source of information and 2) explore different methods to account for missing items.

DESIGN

Cross-sectional design.

SETTING

Nursing home (NH).

PARTICIPANTS

One hundred one residents with dementia.

MEASUREMENTS

NH residents with dementia were assessed on the presence of clinical depression using Provisional Diagnostic Criteria for Depression of Alzheimer's Disease. The MADRS and CSDD were administered in a structured interview with professional primary caregivers.

RESULTS

Receiver operating characteristic analyses revealed no significant differences between areas under the empirical curve for MADRS and CSDD. Imputation of a lowest possible item score for missing items revealed larger areas than three other methods (significant result only for CSDD). A MADRS cutoff score of ">13" yielded the highest sum of sensitivity (78%) and specificity (66%). A CSDD cutoff score of ">6" yielded the highest sum of sensitivity (94%) and specificity (49%). Both scales showed high negative predictive values up to 100% and low positive predictive values not exceeding 50%.

CONCLUSION

The proxy-based MADRS and CSDD did not differ in distinguishing depressed from nondepressed NH residents and may be used for screening purposes. For missing items, imputation of a lowest possib le item score may be applied. The MADRS and CSDD may be better used for ruling out rather than for ruling in depression.

Depression as a predictor of falls amongst institutionalized elders

OBJECTIVE

In this study, we set out to examine the combined effects of medical condition and depression status on fall incidents amongst institutionalized elderly people.

METHODS

A cross-sectional study was carried out to investigate the fall history of institutionalized elders involving 286 subjects. Experiences of falls over the previous year were recorded, with at least two falls during the prior one-year period, or one injurious fall defined as 'fallers'. The Geriatric Depression Scale-15 was used as a screening instrument for depression status.

RESULTS

Based on a multivariate logistic regression and stratification analysis, depression was found to have enhanced effects with various medical conditions on fall risk. As compared with the non-depressive reference group, a five-fold fall risk was discernible amongst depressed elders with multiple medications, whilst a six-fold risk was found amongst depressive elders using ancillary devices, along with a 11-fold amongst depressive elders with neural system diseases.

CONCLUSIONS

This study provides the evidence of enhancing effects between depression and medical conditions on the risk of falls amongst institutionalized elderly people. Thus, depressed elders with neural system diseases, using ancillary devices or multiple medications, should be specifically listed as very high risk of falling amongst institutionalized elderly, and strictly prevent them from falls. Screening and treatment of depression could also be a useful strategy in the prevention of falls amongst institutionalized elderly with poor medical condition.

Nijmegen observer-rated depression scale for detection of depression in nursing home residents

OBJECTIVE

This study aims to test the accuracy of the Nijmegen observer-rated depression (NORD) scale, a new short scale for screening of depression in nursing home (NH) residents with and without dementia.

METHODS

This cross-sectional study with 103 residents with dementia (N = 19 depressed) and 72 residents without dementia (N = 10 depressed) was undertaken in 13 Dutch NH units. An elderly care physician and a psychologist of each unit assessed residents for the presence of clinical depression. Primary professional caregivers administered the NORD scale.

RESULTS

Five of the six proposed items showed acceptable performance in screening for depression. Receiver operating characteristic analyses revealed significant areas under the empirical curve (AUC) for the 5-item NORD scale in the total sample (AUC = 0.83, p < 0.001), as well as in residents with dementia (AUC = 0.84, p < 0.001) and without dementia (AUC = 0.84, p < 0.001). The cutoff score of >1 showed the highest sum of sensitivity (100) and specificity (69) in non-dementia and >2 the highest sum of sensitivity (79) and specificity (77) in dementia. The cutoff score of >1 showed the lowest negative likelihood ratio of 0.0 in non-dementia and of 0.2 in dementia. The highest positive likelihood ratios were found for the cutoff of >2 in non-dementia (3.4) and for >4 in dementia (26.5).

CONCLUSION

The 5-item NORD scale showed acceptable accuracy comparable with those of more extensive scales in other studies. It is easy and quick to administer and can be used for screening of depression in NH residents with or without dementia.

Interactive effect between depression and chronic medical conditions on fall risk in community-dwelling elders

BACKGROUND

It is well documented that fall risk among elderly people is associated with poor health and depression. In this study, we set out to examine the combined effects of medical condition and depression status on fall incidents among community-dwelling elderly people.

METHODS

A cross-sectional study was carried out to investigate the fall history of community-dwelling elders involving 360 participants. Those who had experienced at least two falls over the previous year, or one injurious fall, were defined as "fallers." The Geriatric Depression Scale-15 was used as a screening instrument for depression status.

RESULTS

Based on a multivariate logistic regression and stratification analysis, depression was found to interact with various medical conditions on fall risk. In comparison with the non-depressive reference group, a six-fold fall risk was discernible among depressed elders with polypharmacy, while a five-fold risk was found among depressive elders using ancillary devices, along with a four-fold risk among depressive elders with diabetes or cardiovascular disease. Finally, arthritis was found to produce a nine-fold risk of falls among such populations.

CONCLUSIONS

These findings suggest that greater emphasis should be placed on the integration of depression screening as an element of fall risk assessment in elderly people.

Behavioral disturbance in dementia

Behavioral disturbances are frequently the most challenging manifestations of dementia and are exhibited in almost all people with dementia. Common behavioral disturbances can be grouped into four categories: mood disorders (e.g., depression, apathy, euphoria); sleep disorders (insomnia, hypersomnia, night-day reversal); psychotic symptoms (delusions and hallucinations); and agitation (e.g., pacing, wandering, sexual disinhibition, aggression). They are often persistent, greatly diminish quality of life of patients and their family caregivers, cause premature institutionalization, and pose a high economic burden on the patient, family, and society. Behavioral disturbances can be prevented and treated with a multifaceted approach that supports dignity and promotes comfort and quality of life of persons with dementia and their family members. Management involves prompt treatment of reversible factors and management of symptoms using primarily individualized nonpharmacological interventions. Pharmacological interventions need to be restricted to behavioral emergencies and for short-term treatment of behavioral disturbances that pose imminent danger to self or others.

Measuring symptoms of depression: comparing the Cornell Scale for Depression in Dementia and the Patient Health Questionnaire-9-Observation Version

The purpose of this study was to extend available psychometric data on the Patient Health Questionnaire-9-Observation Version (PHQ-9-OV) by comparing it with the Cornell Scale for Depression in Dementia (CSDD) in a new sample of long-term care residents. Data were collected post intervention in a quasi-experimental storytelling study across six communities. The sample (N = 54) was 87% women with mean age of 84.5, mean CSDD score of 3.96, and mean PHQ-9-OV score of 4.22. Prevalence of depressive symptoms by CSDD criteria was 20.4% and by PHQ-9-OV criteria was 40.7%. The CSDD and PHQ-9-OV were well correlated (r(s) = 0.78, p < 0.0001). Neither scale was significantly correlated with depression diagnosis nor antidepressant agent use. Both measures demonstrated adequate reliability. The PHQ-9-OV item scoring and established cut-off points designate a lower threshold than the CSDD to detect clinically significant depressive symptoms. Further study is needed to determine the sensitivity of the PHQ-9-OV in identifying treatment effects.

Evaluating the Cornell Scale for Depression in Dementia as a proxy measure in nursing home residents with and without dementia

OBJECTIVES

We evaluated the use of the Cornell Scale for Depression in Dementia (CSDD) as a proxy measure. Study questions were: How do residents' self-reports on the CSDD compare with the nurse proxy CSDD ratings of the resident? How do characteristics of depression as rated by the resident CSDD and the nurse CSDD compare? To what extent are demographic and clinical variables associated with resident CSDD, nurse CSDD, and the discrepancy between resident and nurse CSDD scores?

METHODS

Residents and nurse proxy pairs (n=395 pairs) from 28 nursing homes (NHs) participated. We calculated discrepancy scores for total and subscale CSDD scores, examined correlations between resident and nurse CSDD scores, and described rates of clinical depression using each of the scores. We conducted multivariate analyses to examine factors associated with resident and nurse CSDD and discrepancy scores.

RESULTS

On average, participants had mild cognitive impairment, were White, and female. Associations between resident and nurse CSDD were low (r=0.16). The mean discrepancy score was -2.03 (SD=5.28, p<0.001), indicating that nurses evaluated residents as less depressed than residents evaluated themselves. Discrepancy scores were not associated with residents' cognitive status, but were associated with a measure of self-report reliability. Regression analyses indicated that depression diagnosis accounted for a small but significant association with resident CSDD, but was not significantly associated with nurse CSDD.

CONCLUSION

These findings underscore the importance of obtaining resident input when assessing depression in NH residents with dementia, and educating NH nurses in the most effective ways to assess depression.

The effects of a nursing guideline on depression in psychogeriatric nursing home residents with dementia

OBJECTIVE

To study the effects of introducing a nursing guideline on depression in residents with dementia of psychogeriatric nursing home wards.

METHODS

A multi-center controlled clinical trial with randomization at ward level was used to study the effects of the guideline introduction. Nursing teams were trained in applying the guideline to their own residents diagnosed with depression in dementia. Key elements of the nursing guideline are increasing individualized pleasant activities and decreasing unpleasant events. Participating residents were 97 residents diagnosed with dementia and comorbid depression, from 18 psychogeriatric nursing home wards, in 9 Dutch nursing homes. Measurements took place at pre-test, post-test and follow-up. Primary outcome was severity of depression measured with the MDS/RAI-Depression Rating Scale (DRS) and the Cornell Scale for Depression in Dementia. Secondary outcome is mood as measured by the FACE-observation scale.

RESULTS

Compliance with the nursing guideline was moderate. Despite this, residents on the experimental wards showed a significant reduction in depression on the DRS. With the Cornell scale a reduction of depression was found as well, although not significantly different from that in the control group. No effects on observed mood were found.

CONCLUSION

This study shows significant reductions in depression severity by introducing a nursing guideline on psychogeriatric nursing home wards. Better compliance with the guideline could probably enlarge the effects. Some ways to achieve enhanced compliance are: (1) additionally train non-certified nurse assistants, and (2) emphasize necessary conditions for successful introduction of the guideline to nursing team managers.

Depression in older people living in residential homes

There is a large body of published research relating to depression in residential homes for older people (also called long-term-care homes, and including both nursing homes and hostels) (Ames 1990; 1993; Seitzet al., 2010; Snowdon and Purandare, 2010; Snowdon, 2010). However, despite increased detection and more frequent treatment in recent years, depression remains a significant problem for many older people living in such settings. This guest editorial summarizes current knowledge about prevalence, etiology, detection and screening, treatment and outcomes of depression in residential homes and concludes with a summary of key issues requiring urgent future action.

Act In case of Depression: the evaluation of a care program to improve the detection and treatment of depression in nursing homes. Study Protocol

BACKGROUND

The aim of this study is evaluating the (cost-) effectiveness of a multidisciplinary, evidence based care program to improve the management of depression in nursing home residents of somatic and dementia special care units. The care program is an evidence based standardization of the management of depression, including standardized use of measurement instruments and diagnostical methods, and protocolized psychosocial, psychological and pharmacological treatment.

METHODS/DESIGN

In a 19-month longitudinal controlled study using a stepped wedge design, 14 somatic and 14 dementia special care units will implement the care program. All residents who give informed consent on the participating units will be included. Primary outcomes are the frequency of depression on the units and quality of life of residents on the units. The effect of the care program will be estimated using multilevel regression analysis. Secondary outcomes include accuracy of depression-detection in usual care, prevalence of depression-diagnosis in the intervention group, and response to treatment of depressed residents. An economic evaluation from a health care perspective will also be carried out.

DISCUSSION

The care program is expected to be effective in reducing the frequency of depression and in increasing the quality of life of residents. The study will further provide insight in the cost-effectiveness of the care program.

Social engagement and depressive symptoms of elderly residents with dementia: a cross-sectional study of 37 long-term care units

BACKGROUND

Social engagement and depression are important outcomes for residents with dementia in long-term care. However, it is still largely unclear which differences in social engagement and depression exist in residents of various long-term care settings and how these differences may be explained. This study investigated the relationship between social engagement and depressive symptoms in long-term care dementia units, and studied whether differences in social engagement and depressive symptoms between units can be ascribed to the composition of the resident population or to differences in type of care setting.

METHODS

Thirty-seven long-term care units for residents with dementia in nursing- and residential homes in the Netherlands participated in the study. Social engagement and depressive symptoms were measured for 502 residents with the Minimum Data Set of the Resident Assessment Instrument. Results were analyzed using multilevel analysis.

RESULTS

Residents of psychogeriatric units in nursing homes experienced low social engagement. Depressive symptoms were most often found in residents of psychogeriatric units in residential homes. Multilevel analyses showed that social engagement and depressive symptoms correlated moderately on the level of the units. This correlation disappeared when the characteristics of residents were taken into account.

CONCLUSIONS

Social engagement and depressive symptoms are influenced not only by individual characteristics but also by the type of care setting in which residents live. However, in this study social engagement and depressive symptoms were not strongly related to each other, implying that separate interventions are needed to improve both outcomes.

Nursing home care for people with dementia and residents' quality of life, quality of care and staff well-being: design of the Living Arrangements for people with Dementia (LAD)-study

BACKGROUND

There is limited information available on how characteristics of the organization of nursing home care and especially group living home care and staff ratio contribute to care staff well being, quality of care and residents' quality of life. Furthermore, it is unknown what the consequences of the increasingly small scale organization of care are for the amount of care staff required in 2030 when there will be much more older people with dementia.

METHODS/DESIGN

This manuscript describes the design of the 'Living Arrangements for people with Dementia study' (LAD-study). The aim of this study is to include living arrangements from every part of this spectrum, ranging from large scale nursing homes to small group living homes. The LAD-study exists of quantitative and qualitative research. Primary outcomes of the quantitative study are wellbeing of care staff, quality of care and quality of life of residents. Furthermore, data concerning staff ratio and characteristics of the living arrangements such as group living home care characteristics are assessed. To get more in-depth insight into the barriers and facilitators in living arrangements for people with dementia to provide good care, focus groups and Dementia Care Mapping are carried out.

DISCUSSION

Results of this study are important for policymakers, directors and staff of living arrangements providing nursing home care to people with dementia and essential for the development of methods to improve quality of care, residents' and staff well-being. Data collection will be repeated every two years, to generate knowledge on the results of changing policies in this field.

No longer undertreated? Depression diagnosis and antidepressant therapy in elderly long-stay nursing home residents, 1999 to 2007

OBJECTIVES

To examine the evolution of depression identification and use of antidepressants in elderly long-stay nursing home residents from 1999 through 2007 and the associated sociodemographic and facility characteristics.

DESIGN

Annual cross-sectional analysis of merged resident assessment data from the Minimum Data Set (MDS) and facility characteristics from the Online Survey Certification and Reporting data.

SETTING

Nursing homes in eight states (5,445 facilities).

PARTICIPANTS

Long-stay nursing home residents aged 65 and older (2,564,687 assessments).

MEASUREMENTS

Physician-documented depression diagnoses recorded in the MDS were used to identify residents with depression; antidepressant use was measured using MDS information about residents' receipt of an antidepressant in the 7 days before assessment.

RESULTS

Diagnosis of depression and antidepressant therapy in residents diagnosed increased at a rapid rate. By 2007, 51.8% of residents were diagnosed with depression, 82.8% of whom received an antidepressant. Adjusted odds of treatment were higher for younger residents, whites, and those with moderate impairment of cognitive function.

CONCLUSION

This study demonstrates striking increases in depression diagnosis and treatment with antidepressant medications, but disparities persist without clear evidence about underlying mechanisms. More research is needed to assess effectiveness of antidepressant prescribing.
