Do behavioral disturbances predict falls among nursing home residents?

Incidence and Risk Factors of Falls Among Older People in Nursing Homes: Systematic Review and Meta-Analysis

OBJECTIVES

Falls are common among older people in nursing homes, and the assessment of fall risk factors is critical for the success of fall prevention interventions. This study aimed to systematically assess the incidence and risk factors of falls in older people living in nursing homes.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Older people living in nursing homes.

METHODS

Literature searches were conducted independently by 2 researchers in 8 databases. Qualities of included studies were assessed using the Newcastle-Ottawa Scale. The prevalence and risk factors of falls were analyzed with a random effects model. All analyses were performed by R software, x64 4.2.2.

RESULTS

In 18 prospective studies addressing older adults living in nursing homes, the pooled incidence of falls was 43% (95% CI 38%-49%), and the meta-regression analysis indicated that the incidence generally decreased from 1998 to 2021. The following risk factors had a strong association with all falls: fall history, impaired ADL performance, insomnia, and depression. Risk factors with low to moderate correlation were vertigo, walking aids, poor balance, use of antidepressants, use of benzodiazepines, use of antipsychotics, use of anxiolytics, polypharmacy, dementia, unsteady gait, hearing problems, and gender (being male). Having bed rails was identified as a protective environmental factor.

CONCLUSIONS AND IMPLICATIONS

The results from our meta-analysis suggest that the incidence of falls of older adults living in nursing homes is high, and the risk factors for falls are various. Assessments of balance and mobility, medical condition, and use of medications should be included as key elements in the fall risk assessments of older people in nursing homes. Environmental risk factors still need to be explored in future studies. Tailored fall prevention strategies should be implemented by addressing the modifiable risk factors.

Neuropsychiatric Symptoms as Indicators of Fall Risk in Geriatric Inpatients

Background and Objectives: It is well established that patients with cognitive impairment are at a higher risk of falls. However, the impact of coexisting neuropsychiatric symptoms on the overall risk of falls in hospitalized geriatric individuals with and without dementia has not been extensively studied. This cross-sectional study will assess the association between neuropsychiatric symptoms and fall risk in geriatric individuals analyzed by sex. Materials and Methods: A total of 234 patients, both with and without dementia, admitted to the geriatric ward at Leszek Giec Upper-Silesian Medical Centre of the Silesian Medical University in Katowice, Poland, between January 2019 and January 2020 were included in this study. The Neuropsychiatric Inventory-Questionnaire was used to assess the presence of neuropsychiatric symptoms. Increased fall risk was defined by Berg scores of ≤40. Results: The mean age of the study group was 80.7 ± 6.6, and women accounted for 62.8% of the study population. Apathy was the most common neuropsychiatric symptom, affecting 58.1% of patients, and it was the most common symptom among people with dementia, affecting 67.80% of patients. The receiver operating characteristics curve analysis revealed that a high fall risk was significantly associated with the total number of neuropsychiatric symptoms (≥4) and the total intensity of these symptoms (≥6). For women, high fall risk was associated with three or more neuropsychiatric symptoms and a total neuropsychiatric symptom intensity score of at least 6. For men, the association of high fall risk with the total number of NPS was not significant; a total NPS intensity score of 10 or more was associated with high fall risk. Multivariate logistic regression analysis identified associations with fall risk for hallucinations. Conclusions: Our results suggest that the presence of neuropsychiatric symptoms, particularly hallucinations is associated with an increased risk of falls in geriatric inpatients. In addition, the cumulative total of NPS and their cumulative intensity are both independently associated with an increased risk of falls. These results suggest that fall prevention strategies should include the management of neuropsychiatric symptoms in hospitalized geriatric individuals.

Preventing falls: the use of machine learning for the prediction of future falls in individuals without history of fall

Nowadays, it becomes of paramount societal importance to support many frail-prone groups in our society (elderly, patients with neurodegenerative diseases, etc.) to remain socially and physically active, maintain their quality of life, and avoid their loss of autonomy. Once older people enter the prefrail stage, they are already likely to experience falls whose consequences may accelerate the deterioration of their quality of life (injuries, fear of falling, reduction of physical activity). In that context, detecting frailty and high risk of fall at an early stage is the first line of defense against the detrimental consequences of fall. The second line of defense would be to develop original protocols to detect future fallers before any fall occur. This paper briefly summarizes the current advancements and perspectives that may arise from the combination of affordable and easy-to-use non-wearable systems (force platforms, 3D tracking motion systems), wearable systems (accelerometers, gyroscopes, inertial measurement units-IMUs) with appropriate machine learning analytics, as well as the efforts to address these challenges.

Usability Evaluation of an Offline Electronic Data Capture App in a Prospective Multicenter Dementia Registry (digiDEM Bayern): Mixed Method Study

BACKGROUND

Digital registries have been shown to provide an efficient way of gaining a better understanding of the clinical complexity and long-term progression of diseases. The paperless method of electronic data capture (EDC) during a patient interview saves both time and resources. In the prospective multicenter project "Digital Dementia Registry Bavaria (digiDEM Bayern)," interviews are also performed on site in rural areas with unreliable internet connectivity. It must be ensured that EDC can still be performed in such a context and that there is no need to fall back on paper-based questionnaires. In addition to a web-based data collection solution, the EDC system REDCap (Research Electronic Data Capture) offers the option to collect data offline via an app and to synchronize it afterward.

OBJECTIVE

The aim of this study was to evaluate the usability of the REDCap app as an offline EDC option for a lay user group and to examine the necessary technology acceptance of using mobile devices for data collection. The feasibility of the app-based offline data collection in the digiDEM Bayern dementia registry project was then evaluated before going live.

METHODS

An exploratory mixed method design was employed in the form of an on-site usability test with the "Thinking Aloud" method combined with an online questionnaire including the System Usability Scale (SUS). The acceptance of mobile devices for data collection was surveyed based on five categories of the technology acceptance model.

RESULTS

Using the "Thinking Aloud" method, usability issues were identified and solutions were accordingly derived. Evaluation of the REDCap app resulted in a SUS score of 74, which represents "good" usability. After evaluating the technology acceptance questionnaire, it can be concluded that the lay user group is open to mobile devices as interview tools.

CONCLUSIONS

The usability evaluation results show that a lay user group generally agree that data collecting partners in the digiDEM project can handle the REDCap app well. The usability evaluation provided statements about positive aspects and could also identify usability issues relating to the REDCap app. In addition, the current technology acceptance in the sample showed that heterogeneous groups of different ages with diverse experiences in handling mobile devices are also ready for the use of app-based EDC systems. Based on these results, it can be assumed that the offline use of an app-based EDC system on mobile devices is a viable solution for collecting data in a decentralized registry-based research project.

Clinical impact of antipsychotic and benzodiazepine reduction: findings from a multicomponent psychotropic reduction program within long-term aged care

OBJECTIVES

To explore the relationships between dose changes to antipsychotic and/or benzodiazepine medications and resident outcomes, including variations in neuropsychiatric symptoms, quality of life (QoL), and social withdrawal, within a multicomponent, interdisciplinary antipsychotic and benzodiazepine dose reduction program.

DESIGN

Prospective, observational, longitudinal study.

INTERVENTION

The Reducing Use of Sedatives (RedUSe) project involved 150 Australian Long-Term Care Facilities (LTCFs) incorporating auditing and benchmarking of prescribing, education, and multidisciplinary sedative reviews.

SETTING

A convenience sample of LTCFs (n = 28) involved in RedUSe between January 2015 and March 2016.

PARTICIPANTS

Permanent residents (n = 206) of LTCFs involved in RedUSe taking an antipsychotic and/or benzodiazepine daily. Residents were excluded if they had a severe psychiatric condition where antipsychotic therapy should generally be maintained long-term (e.g., bipolar disorder, schizophrenia) or were considered end-stage palliative.

MEASUREMENTS

Neuropsychiatric symptoms (Neuropsychiatric Inventory, Cohen-Mansfield Agitation Inventory (CMAI)), QoL (Assessment of Quality of Life-4D), and social withdrawal (Multidimensional Observation Scale for Elderly Subjects-withdrawal subscale) were measured at baseline and 4 months where nursing staff completed psychometric tests as proxy raters.

RESULTS

There was no evidence that psychometric measures were worsened following dose reductions. In fact, dose reduction was associated with small, albeit non-statistically significant, improvements in behavior, particularly less physically non-aggressive behavior with both drug groups (-0.36 points per 10% reduction in antipsychotic dose, -0.17 per 10% reduction in benzodiazepine dose) and verbally agitated behavior with benzodiazepine reduction (-0.16 per 10% dose reduction), as measured with the CMAI. Furthermore, antipsychotic reduction was associated with non-statistically significant improvements in QoL and social withdrawal.

CONCLUSIONS

Antipsychotic and benzodiazepine dose reduction in LTCFs was not associated with deterioration in neuropsychiatric symptoms, QoL, or social withdrawal. Trends toward improved agitation with antipsychotic and benzodiazepine dose reduction require further evaluation in larger, prospective, controlled studies.

Course of activities of daily living in nursing home residents with dementia from admission to 36-month follow-up

Background

Dementia is affecting both the person with the disease and the family members. It is associated with nursing home admission, and a reduced ability to perform personal activities of daily living (P-ADL). The aim of this study was to examine the association between the severity of dementia and P-ADL function, and to study if additional factors such as neuropsychiatric symptoms, type of nursing home unit, and use of medication were associated with P-ADL function.

Methods

A total of 582 nursing home residents with dementia, included at admission to the nursing home, were followed with biannual assessments for 36 months. P-ADL was assessed using the Physical Self-Maintenance scale, and severity of dementia was measured with the Clinical Dementia Rating scale. In addition, neuropsychiatric symptoms, general physical health, and use of medications were assessed at the same time points. Demographic information was collected at baseline. Linear mixed models were estimated.

Results

There was a significant (p < 0.05) non-linear decline in P-ADL function over time in analysis not adjusting for any characteristics. More severe dementia at baseline and at the follow-up assessments was associated with lower P-ADL function (p < 0.001), with the association being stable over time. A higher level of neuropsychiatric symptoms, not using anti-dementia medication, being in a regular care unit as compared to a special care unit and having poor/fair general physical health as compared to good/excellent, were associated with a lower P-ADL function.

Conclusion

The association between more severe dementia and lower P-ADL function was stable over a 36-month follow-up period of nursing home residents with dementia. Health care planners and clinicians should be aware of this when planning for and treating nursing home residents.

Neuropsychiatric Symptoms as Predictors of Falls in Long-Term Care Residents With Cognitive Impairment

OBJECTIVES

Falls and neuropsychiatric symptoms (NPS) are common among long-term care residents with cognitive impairment. Despite the high prevalence of falls and NPS, little is known about their association. The aim of our study was to explore how NPS, particularly the severity of NPS and specific NPS subgroups, are associated with falls and how psychotropics modify this association.

DESIGN

Longitudinal cohort study.

SETTING AND PARTICIPANTS

In total, 532 long-term care residents aged 65 years or older in Helsinki, Finland.

METHODS

NPS were measured with Neuropsychiatric Inventory (NPI) at baseline. Participants were grouped into 3 groups: no significant NPS (NPI points 0‒3), low NPS burden (NPI 4‒12), and high NPS burden (NPI >12). The number of falls, injuries, fractures, and hospitalizations were collected from medical records over 12 months following baseline assessment.

RESULTS

Altogether, 606 falls occurred during the follow-up year. The falls led to 121 injuries, 42 hospitalizations, and 20 fractures. Falls and injuries increased significantly with NPS burden (P < .001): 330 falls in the high NPS group (n = 184), 188 falls in the low NPS group (n = 181), and 88 falls in the no significant NPS group (n = 167). The risk of falling showed a curvilinear association with NPI total score. Of NPS subgroups, psychosis and hyperactivity were associated with a higher incidence rate ratio of falls, whereas apathy had a protective association even after adjustment for age, sex, and mobility. Affective symptoms were not associated with falls. Psychotropics did not modify the association between NPS burden and falls.

CONCLUSIONS AND IMPLICATIONS

The results of this study show that NPS, especially NPS severity, may predict falls and fall-related negative consequences. Severity of NPS should be taken into account when assessing fall risk in long-term care residents with cognitive impairment.

Evaluating Mobility in Advanced Dementia: A Scoping Review and Feasibility Analysis

BACKGROUND AND OBJECTIVES

Mobility decline is a symptom of advanced dementia that affects function, safety, caregiving, and quality of life. Monitoring mobility status is essential for initiating timely and targeted interventions aimed at preventing excess disability in people with dementia (PWD). The physical, cognitive, and behavioral symptoms of dementia however, present unique challenges for mobility assessment. The goals of this review were to (a) identify and describe measures of mobility used for PWD and (b) assess measures' feasibility for use in people with advanced dementia; a group whose degree of cognitive impairment results in severe functional deficits.

RESEARCH DESIGN AND METHODS

Electronic searches of Medline, Embase, CINAHL, and PsychInfo databases were conducted using keywords related to dementia, mobility, measurement, and validation. Descriptive characteristics were extracted and measures coded for mobility components. Tools were also evaluated for feasibility of use in advanced dementia and those deemed feasible, screened for psychometric strength.

RESULTS

Thirty-eight measures were included and 68% of these tools were performance-based. Elements of mobility evaluated were walking (53% of measures), postural transitions (42%), standing (40%), mobility-related behavioral/psychological symptoms (24%), transfers (10%), bed mobility (5%), and wheeled mobility (3%). 36% of studies included people with advanced dementia. Only 18% of tools received high scores for feasibility.

DISCUSSION AND IMPLICATIONS

Existing measures provide only partial information regarding mobility and few target elements that become relevant as dementia progresses. Most measures are not feasible for people with advanced dementia, and the psychometric evaluation of these measures is limited. Further research is needed to develop a comprehensive, dementia-specific, mobility assessment tool.

Key factors for the assessment of mobility in advanced dementia: A consensus approach

Introduction

Loss of mobility is common in advanced dementia and has important negative consequences related to fall risk, loss of independence, and lack of participation in meaningful activities. The causes of decline are multifactorial, including disease-specific changes in motor function, behavior, and cognition. To optimize clinical management of mobility, there is a need to better characterize capacity for safe and independent mobility. This study aimed to identify key factors that impact on mobility in dementia.

Methods

Expert input was gathered using a modified Delphi consensus approach. The primary criterion for participation was specialist knowledge in mobility or dementia, either as a clinician or a researcher. Participants rated elements of mobility for importance and feasibility of assessment in advanced dementia and prioritized items for inclusion in a mobility staging tool. Descriptive statistics and qualitative content analysis were used to summarize responses.

Results

Thirty-six experts completed the first survey with an 80% retention rate over three rounds. One-third of 61 items reached consensus for being both important and feasible to assess, representing five categories of elements. Items reaching agreement for a staging tool included walking, parkinsonism, gait, impulsivity, fall history, agitation, transfers, and posture control.

Discussion

This study highlights the need for a multidimensional, dementia-specific approach to mobility assessment. Results have implications for development of assessment methods and management guidelines to support the clinical care of mobility impairment in people with dementia.

Physical diagnoses in nursing home residents - is dementia or severity of dementia of importance?

Background

Dementia and physical morbidity are primary reasons for nursing home admission globally. However, data on physical morbidity in nursing home residents with and without dementia are scarce. The first aim of the present study was to explore whether presence and severity of dementia were related to the number of physical diagnoses in nursing home residents. The second aim was to explore if the severity of dementia was associated with having registered the most frequent complexes of physical diagnoses when controlling for physical health and demographic factors.

Methods

A total of 2983 Norwegian nursing home residents from two cross-sectional samples from 2004/2005 and 2010/2011 were included in the analysis. By the use of assessment scales, the severity of dementia (Clinical Dementia Rating), physical health (General Medical Health Rating), activities of daily living (Physical Self-Maintenance Scale) and neuropsychiatric symptoms (Neuropsychiatric Inventory Nursing Home) were determined. Physical diagnoses and medications were assembled from the medical records. The physical diagnoses were categorized into complexes, using the ICD-10 chapters. Linear mixed models and generalized linear mixed models were estimated.

Results

Residents with dementia were registered with fewer physical diagnoses than residents without dementia. The frequency of physical diagnoses decreased with increasing severity of dementia. Cardiovascular, musculoskeletal and endocrine, nutritional and metabolic diagnoses were the most common complexes of physical diagnoses in individuals with and without dementia. The odds of having cardiovascular and musculoskeletal diagnoses increased for males and decreased for females with increasing severity of dementia, in contrast to endocrine diagnoses where the odds increased for both genders.

Conclusion

Increasing severity of dementia in nursing home residents may complicate the diagnostics of physical disease. This might reflect a need for more attention to the registration of physical diagnoses in nursing home residents with dementia.

The course of neuropsychiatric symptoms in nursing home residents from admission to 30-month follow-up

Aim

The aim of this study was to describe the prevalence and persistence of clinically significant neuropsychiatric symptoms (NPS) in nursing home residents with dementia, and to study the association between severity of dementia and specific neuropsychiatric sub-syndromes over time.

Methods

In total, 583 residents with dementia were included at admission to a nursing home and followed with biannual assessments until death, or to 30-month follow-up. At the end of the 30-month follow-up, 305 participants had died and 57 had left the study for other reasons, leaving 221 residents in the study. We collected data on demographics, cognition, severity of dementia, NPS, personal activities of daily living (P-ADL), physical health, medication and type of nursing home unit. NPS was assessed using the Neuropsychiatric Inventory (NPI), the Nursing Home version.

Results

The prevalence and persistence at two consecutive time-points of clinically significant NPS was high during the study period. The mean NPI agitation sub-syndrome score increased during the study period, while the NPI affective and psychosis sub-syndrome scores remained unchanged. More severe dementia was associated with higher NPI agitation, psychosis and affective sub-syndrome scores. The association remained unchanged over time for agitation and psychosis. For the NPI affective sub-syndrome, the association was stronger at the beginning, and declined towards the end of the study period.

Conclusion

The findings of high prevalence and persistence at two consecutive time points of clinically significant NPS over time, and the associations between severity of dementia and NPI sub-syndromes shed light on the burden and care needs of nursing home residents with dementia after admission to nursing home care. This information is of interest to health care planners and providers to enable them to increase the quality of care for nursing home residents.

Relationship of Neuropsychiatric Symptoms with Falls in Alzheimer's Disease - Does Exercise Modify the Risk?

OBJECTIVES

To explore how neuropsychiatric symptoms (NPS) are associated with number of falls and how exercise modifies the risk of falling in community-dwelling people with Alzheimer's disease (AD) and NPS.

DESIGN

Secondary analysis of a randomized controlled trial.

SETTING

Community.

PARTICIPANTS

Community-dwelling individuals with AD (N=210) who completed the Neuropsychiatric Inventory (NPI) (N = 179).

INTERVENTION

Participants were randomized into 3 groups: group-based exercise (4-hour sessions with approximately 1 hour of training) and tailored home-based exercise (1 hour of training) twice a week for 1 year and a control group receiving usual community care. In this secondary analysis, we merged the home-based and group-based exercise groups and compared this group with the control group.

MEASUREMENTS

NPS were measured using the NPI at baseline, and spousal caregivers recorded falls in daily fall diaries during 1 year of follow-up.

RESULTS

The number of falls increased linearly with NPI score in the control group. Fall rates were 1.48 (95% confidence interval (CI)=1.26-1.73) per person-year in the intervention group and 2.87 (95% CI=2.43-3.35) in the control group. Adjusted for age, sex, Mini-Mental State Examination (MMSE) score, and Short Physical Performance Battery (SPPB) score, incidence rate ratio (IRR) was 0.48 (95% Cl=0.39-0.60, p < .001). Main effects for fall rate were significant for group (p < .001) and NPI total (p < .02); the interaction effect was also significant (p = .009) (adjusted for sex, age, MMSE score, SPPB score, and psychotropic medication use).

CONCLUSION

Exercise may decrease the risk of falling in community-dwelling individuals with AD and NPS. Future exercise trials should confirm this finding in participants with significant NPS.

Predictors of Falls and Fractures Leading to Hospitalization in People With Dementia: A Representative Cohort Study

OBJECTIVES

Investigate predictors of falls and fractures leading to hospitalization in a large cohort of people with dementia.

DESIGN

A retrospective cohort study.

SETTING AND PARTICIPANTS

People with diagnosed dementia between January 2007 and March 2013, aged >65 years, were assembled using data from the Maudsley Biomedical Research Centre Case Register, from 4 boroughs in London serving a population of 1.3 million people.

MEASURES

Falls and/or fractures leading to hospitalization were ascertained from linked national records. Demographic data, cognitive test scores, medications, and symptom and functioning scores from Health of the Nation Outcome Scales (HoNOS65+) were modeled in multivariate survival analyses to identify predictors of falls and fractures.

RESULTS

Of 8036 people with dementia (63.9% female), 2500 (31.1%, incidence rate 125.5 per 1000 person-years) had a fall during a mean follow-up of 2.5 years and 1437 (17.7%, incidence rate 65.5 per 1000 person-years) had a fracture. In multivariable models, significant predictors of falls were increased age, female gender, physical health problems, previous fall or fracture, vascular dementia vs Alzheimer's disease, higher neighborhood deprivation, noncohabiting status, and problems with living conditions. Ethnic minority status was protective of falls (eg, Caribbean/Asian ethnicity). Medications (including psychotropic and antipsychotics), neuropsychiatric symptoms, cognitive (Mini-Mental State Examination scores), or functional problems did not predict hospitalized falls. Predictors of fractures were similar to those predicting falls.

IMPLICATIONS

Over an average of 2.5 years, a third of people with dementia had a fall leading to hospitalization, necessitating action in clinical practice. Clinicians should consider that besides established demographic and physical health-related factors, the risk of hospitalization due to a fall or fractures in dementia is largely determined by environmental and socioeconomic factors. Interestingly, our data suggest that neuropsychiatric symptoms, cognitive status, functioning, or pharmacotherapy were not associated with falls/fractures.

A Palliative Approach to Falls in Advanced Dementia

Falls are viewed as a preventable cause of injury, functional loss, and death in older adults with dementia, and have been used as a marker of quality of care in long-term care facilities. Despite intensive intervention around fall prevention in these settings, falls and injury remain frequent, particularly among residents in the advanced stages of dementia. In this clinical review, we consider the common challenges and pitfalls in both the management of falls and the provision of palliative care in advanced dementia. We then describe a palliative approach to falls in advanced dementia that involves identifying individuals who would benefit from this care approach, framing falls and loss of mobility as a quality of life issue, and devising an individualized symptom assessment and management plan. A palliative approach can lead to recognition and acceptance that recurrent falls are often symptomatic of advanced dementia, and that not all falls are preventable. We conclude that falls in the advanced stage of dementia can be sentinel events indicating the need for a palliative approach to care. Rather than replace falls prevention activities, a palliative approach to falls prompts us to select dementia stage-appropriate interventions with a focus on symptom management, comfort, and dignity.

Can depression in psychogeriatric inpatients at one year follow-up be explained by locus of control and coping strategies?

OBJECTIVES

Treatment of depression (in late life) is good. The short-term, but not long-term prognosis after treatment of depression in late life is good. To identify modifiable factors, we wanted to examine whether coping in terms of locus of control and coping strategies in depressed patients were associated with the prognosis of depression at follow-up, adjusted for sociodemographic information and health variables.

METHOD

In total, 122 patients (mean age 75.4 years; SD = 6.6) were followed up (median 13.7 months, Q1-Q3 386-441) with a diagnostic evaluation(ICD-10) for depression and assessment of depressive symptoms (MADRS). Coping was assessed using Locus of Control of behavior (LoC-scale) and Ways of Coping questionnaire (WoC-scale).

RESULTS

At follow-up, 37.7% were diagnosed with a depressive episode. A stronger external LoC and lower MMSE-NR score at baseline were in adjusted linear regression analysis significantly more associated to higher depressive symptom scores (MADRS). More use of problem-focused coping, a lower I-ADL functioning, but not emotion-focused coping at baseline were significantly associated with being depressed (ICD-10), at follow-up in adjusted logistic regression analysis.

CONCLUSION

LoC and coping strategies at baseline were associated with the prognosis of depression at follow-up, and may further be studied as indicators for choice of baseline intervention strategies.

Persistent use of psychotropic drugs in nursing home residents in Norway

Background

The prevalence of psychotropic drug (PTD) use in NH residents is high, but few have explored prevalence and persistency in PTD in NH residents and factors associated with persistency. This at the same time as we know that risk of side events may be higher with long- term use in older adults. Thus, the aim of this study was to describe the prevalence and persistence in use of PTD and to explore factors associated with persistence in use of PTD at two consecutive time points in nursing home (NH) residents.

Methods

We included 1163 NH residents in a 72-month longitudinal study with five assessments. Use of PTD, neuropsychiatric symptoms (NPS), severity of dementia and physical health were assessed each time.

Results

The prevalence over time and persistent use of antipsychotic drugs, antidepressants, anxiolytics and sedatives at two consecutive time points were high in residents with and without dementia. There was an association between greater NPS at the first time point, and persistent use of these drugs, but changes in NPS between time points, did not explain such use. A longer NH stay increased the odds for persistent use of antipsychotics.

Conclusion

Psychotropic drugs are frequently used as a long-term treatment among NH residents and are associated with severity of neuropsychiatric symptoms, but not with severity of dementia. Closer attention should be paid to follow-up of psychotropic drug treatment, and especially for long –term use of antipsychotics, since the duration of such treatment should be as short as possible.

Influence of cognitive impairment on fall risk among elderly nursing home residents

BACKGROUND

Information relating the severity of cognitive decline to the fall risk in institutionalized older adults is still scarce. This study aims to identify potential fall risk factors (medications, behavior, motor function, and neuropsychological disturbances) depending on the severity of cognitive impairment in nursing home residents.

METHODS

A total of 1,167 nursing home residents (mean age 81.44 ± 8.26 years; 66.4% women) participated in the study. According to the MEC, (the Spanish version of the Mini-Mental State Examination) three levels of cognitive impairment were established: mild (20-24) "MCI", moderate (14-19) "MOCI", and severe (≤14) "SCI". Scores above 24 points indicated the absence cognitive impairment (NCI). Information regarding fall history and fall risk during the previous year was collected using standardized questionnaires and tests.

RESULTS

Sixty falls (34%) were registered among NCI participants and 417 (43%) among people with cognitive impairment (MCI: 35%; MOCI: 40%; SCI: 50%). A different fall risk model was observed for MCI, MOCI, SCI, and NCI patients. The results imply that the higher the level of cognitive impairment, the greater the number of falls (F1,481 = 113.852; Sig = 0.015), although the level of significance was not maintained when MOCI and SCI participants were compared. Depression, neuropsychiatric disturbances, autonomy constraints in daily life activity performance, and low functional mobility were factors closely associated with fall risk.

CONCLUSION

This study provides evidence indicating that fall risk factors do not hold a direct correlation with the level of cognitive impairment among elderly nursing home care residents.

Locus of control and coping strategies in older persons with and without depression

OBJECTIVES

To compare locus of control and coping strategies in older persons with and without depression.

METHOD

This cross-sectional study included 144 depressed in-patients from seven psychogeriatric hospital units, and 106 community-dwelling older persons without depression. All participants were 60 years and older. Locus of control was assessed by a 17-items self-report questionnaire with six response categories. Coping strategies were assessed by a 26-items self-report questionnaire with five response categories. For analytical purposes, age (<75 years vs. ≥75 years), level of education (<10 years vs. ≥10 years) and general medical health (poor vs. not poor) were categorized.

RESULTS

In linear regression analysis, controlling for demographics, health, and social variables, the depressed in-patients showed a higher external locus of control orientation and a less frequent use of problem-focused coping strategies compared with the non-depressed group. No differences in use of emotion-focused strategies were found between the two groups.

CONCLUSION

Compared with the non-depressed old persons, the depressed hospitalized older persons were characterized by perceptions of less personal control, and less use of problem-focused strategies, what also might have brought positive alterations into their situation.

Health-related quality of life in older depressed psychogeriatric patients: one year follow-up

Background

Knowledge about long-term change in health related quality of life (HQoL) among older adults after hospitalization for treatment of depression has clinical relevance. The aim was firstly to describe the change of HQoL one year after admission for treatment of depression, secondly to explore if improved HQoL was associated with remission of depression at follow-up and lastly to study how HQoL in patients with remission from depression were compared to a reference group of older persons without depression.

Method

This study had the one year follow-up information of 108 older patients (≥60 years), all hospitalized for depression at baseline, and a reference sample of 106 community-living older adults (≥60 years) without depression. HQoL was measured using the EuroQol Group’s EQ-5D Index and a visual analog scale (EQ-VAS). Depression and remission were diagnosed according to ICD-10. Socio-demographic variables (age, gender, and education), depressive symptom score (Montgomery-Aasberg Depression Rating Scale), cognitive functioning (Mini Mental State Examination scale), instrumental activities of daily living (the Lawton and Brody’s Instrumental Activities of Daily Living Scale), and poor general physical health (General Medical Health Rating) were included as covariates.

Results

HQoL had improved at follow-up for the total group of depressed patients, as indicated by better scores on the EQ-5D Index and EQ-VAS. In the multivariate linear regression model, improved EQ-5D Index and EQ-VAS was significantly better in those with remission of depression and those with better baseline physical health. In adjusted analyses, the HQoL in patients with remission from depression at follow-up did not differ from the HQoL in a reference group without depression.

Conclusion

Older hospital patients with depression who experienced remission one year after admission gained HQoL and their HQoL was comparable with the HQoL in a reference group of older adults without depression when adjusting for differences in socio-demographics and health conditions.

Anticholinergic drugs and negative outcomes in the older population: from biological plausibility to clinical evidence

The use of medication with anticholinergic properties is widespread among older subjects. Many drugs of common use such as antispasmodics, bronchodilators, antiarrhythmics, antihistamines, anti-hypertensive drugs, antiparkinson agents, skeletal muscle relaxants, and psychotropic drugs have been demonstrated to have an anticholinergic activity. The most frequent adverse effects are dry mouth, nausea, vomiting, constipation, abdominal pain, urinary retention, blurred vision, tachycardia and neurologic impairment such as confusion, agitation and coma. A growing evidence from experimental studies and clinical observations suggests that drugs with anticholinergic properties can cause physical and mental impairment in the elderly population. However, the morbidity and management issues associated with unwanted anticholinergic activity are underestimated and frequently overlooked. Moreover, their possible relation with specific negative outcome in the elderly population is still not firmly established. The aim of the present review was to evaluate the relationship between the use of drugs with anticholinergic activity and negative outcomes in older persons. We searched PubMed and Cochrane combining the search terms "anticholinergic", "delirium", "cognitive impairment", "falls", "mortality" and "discontinuation". Medicines with anticholinergic properties may increase the risks of functional and cognitive decline, morbidity, institutionalization and mortality in older people. However, such evidences are still not conclusive probably due to possible confounding factors. In particular, more studies are needed to investigate the effects of discontinuation of drug with anticholinergic properties. Overall, minimizing anticholinergic burden should always be encouraged in clinical practice to improve short-term memory, confusion and delirium, quality of life and daily functioning.

Severity of Neuropsychiatric Symptoms in Nursing Home Residents

We aimed at assessing time shift in the severity of neuropsychiatric symptoms (NPS) in nursing home residents between 2004/2005 and 2010/2011 and associations between NPS and socio-demographic variables, physical health status, dementia severity, and the use of psychotropic drugs. The Neuropsychiatric Inventory Nursing Home Version was used in 2004/2005 (n = 1,163) and 2010/2011 (n = 1,858). Linear mixed model analysis was applied. There was no time shift in the severity of apathy, psychosis, and affective symptoms, but agitation did exhibit a time shift. Agitation was less severe in 2010/2011 than in 2004/2005 in residents with a Clinical Dementia Rating (CDR) sum of boxes score ≤4, and more severe in residents with a CDR sum of boxes score >16. Higher CDR sum of boxes scores and use of psychotropic medication were associated with more severe apathy, agitation, psychosis, and affective symptoms. Poor physical health was associated with more severe apathy, psychosis, and affective symptoms. Women had more severe agitation and less severe affective symptoms than men. A longer stay in a nursing home was associated with more severe agitation and less severe affective symptoms. In conclusion, agitation was less severe in 2010/2011 than in 2004/2005 among nursing home residents with a milder degree of dementia, and more severe in residents with severe dementia.

Long-term effects of a 12 weeks high-intensity functional exercise program on physical function and mental health in nursing home residents with dementia: a single blinded randomized controlled trial

Background

Research indicates that exercise can have a positive effect on both physical and mental health in nursing home patients with dementia, however the lasting effect is rarely studied. In a previously published article we investigated the immediate effect of a 12 weeks functional exercise program on physical function and mental health in nursing home residents with dementia. In this paper we studied the long-term effect of this exercise program. We explored the differences between the exercise and control group from baseline to 6 months follow-up and during the detraining period from month 3 to 6.

Methods

A single blind, randomized controlled trial was conducted and a total of 170 nursing home residents with dementia were included. The participants were randomly allocated to an intervention (n = 87) or a control group (n = 83). The intervention consisted of intensive strengthening and balance exercises in small groups twice a week for 12 weeks. The control condition was leisure activities. Thirty participants were lost between baseline and six-month follow-up. Linear mixed model analyses for repeated measurements were used to investigate the effect of exercise after detraining period.

Results

The exercise group improved their scores on Berg Balance Scale from baseline to 6 months follow-up by 2.7 points in average. The control group deteriorated in the same period and the difference between groups was statistically significant (p = 0.031). The exercise group also scored better on NPI agitation sub-score after 6 months (p = 0.045).

Conclusion

The results demonstrate long-time positive effects of a high intensity functional exercise program on balance and indicate a positive effect on agitation, after an intervention period of 12 weeks followed by a detraining period of 12 weeks.

Initiation of Antidepressant Medication After Hip Fracture in Community-Dwelling Older Adults

OBJECTIVE

To evaluate the incidence, characteristics, and correlates of antidepressant drug therapy initiation among community-dwelling older adults following hip fracture.

DESIGN

Retrospective cohort study using linked, population-based administrative data.

SETTING

Province of Ontario, Canada.

PARTICIPANTS

Older adults, aged 65 years or older, with a hip fracture and hip fracture surgery between April 1, 2003, and February 28, 2011. The study sample was restricted to individuals who returned home following surgery and who had not been dispensed an antidepressant in the year prior to their fracture (N=25,436).

MEASUREMENTS

We determined the incidence of new antidepressant use defined by the dispensing of antidepressant drug therapy within 90 days of discharge home. We identified independent correlates of antidepressant initiation using multivariate regression.

RESULTS

Overall, antidepressants were newly initiated in 8.8% of older adults with hip fracture in the 90 days following hospital discharge. There was a statistically significant, 1.3-fold increase in incidence of antidepressant prescribing from 2003 to 2010. Trazodone, frequently prescribed at a low dose, accounted for 39.0% of newly dispensed antidepressants, followed by selective serotonin reuptake inhibitors (36.9%). Rehabilitation admission, psychiatric evaluation, a diagnosis of dementia, and baseline benzodiazepine use were the strongest independent correlates of antidepressant initiation.

CONCLUSION

The period after a hip fracture is associated with a high rate of initiation of antidepressant therapy. The data raise the possibility that antidepressants are frequently prescribed off-label in these patients. Further research is needed to investigate the safety and efficacy of antidepressant use in this vulnerable population.

Cause or Effect? Selective Serotonin Reuptake Inhibitors and Falls in Older Adults: A Systematic Review

A 2012 update of the Beers criteria categorizes selective serotonin reuptake inhibitors (SSRIs) as potentially inappropriate medications in all older adults based on fall risk. The application of these recommendations, not only to frail nursing home residents, but to all older adults, may lead to changes in health policy or clinical practice with harmful consequences. A systematic review of studies on the association between SSRIs and falls in older adults was conducted to examine the evidence for causation. Twenty-six studies met the inclusion criteria. The majority of studies were observational and suggest an association between SSRIs and falls. The direction of the relationship--causation or effect--cannot be discerned from this type of study. Standardized techniques for determining likely causation were then used to see if there was support for the hypothesis that SSRIs lead to falls. This analysis did not suggest causation was likely. There is no Level 1 evidence that SSRIs cause falls. Therefore, changes in the current treatment guidelines or policies on the use of SSRIs in older adults based on fall risk may not be justified at this time given the lack of an established evidence base. Given its significance to public health, well-designed experimental studies are required to address this question definitively.

Medications associated with falls in older people: systematic review of publications from a recent 5-year period

PURPOSE

Falls are an important public health problem in older people. Medication use is considered a risk factor for falls. This study systematically reviewed recent studies to determine the medications that might be associated with the risk of falling in older people.

METHODS

We conducted a systematic review of prospective and retrospective studies identified through the MEDLINE and CINAHL databases that quantitatively assessed the contribution of medications to falls risk in participants ≥60 years old published in English between May 2008 and April 2013.

RESULTS

The search identified 1,895 articles; 36 articles met the inclusion criteria. Of the 19 studies that investigated the effect of polypharmacy on the risk of falling, six studies reported that the risk of falling increased with polypharmacy. Data on the use of antihypertensive medications including calcium channel blockers, beta-blockers, and angiotensin system blocking medications were collected in 14 studies, with mixed results. Twenty-nine studies reported an association between the risk of falls and psychotropic medications including sedatives and hypnotics, antidepressants, and benzodiazepines.

CONCLUSIONS

The use of sedatives and hypnotics and antidepressants including tricyclic antidepressants, selective serotonin reuptake inhibitors, and serotonin norepinephrine reuptake inhibitors appears to be related with an increased risk of falls. It is not clear if the use of antihypertensive medications is associated with the risk of falls in older people.

Effect of a high-intensity exercise program on physical function and mental health in nursing home residents with dementia: an assessor blinded randomized controlled trial

BACKGROUND

Dementia is among the leading causes of functional loss and disability in older adults. Research has demonstrated that nursing home patients without dementia can improve their function in activities of daily living, strength, balance and mental well being by physical exercise. The evidence on effect of physical exercise among nursing home patients with dementia is scarce and ambiguous. Thus, the primary objective of this study was to investigate the effect of a high intensity functional exercise program on the performance of balance in nursing home residents with dementia. The secondary objective was to examine the effect of this exercise on muscle strength, mobility, activities of daily living, quality of life and neuropsychiatric symptoms.

DESIGN AND METHODS

This single blinded randomized controlled trial was conducted among 170 persons with dementia living in nursing homes. Mean age was 86.7 years (SD = 7.4) and 74% were women. The participants were randomly allocated to an intervention (n = 87) or a control group (n = 83). The intervention consisted of intensive strengthening and balance exercises in small groups twice a week for 12 weeks. The control condition was leisure activities.

RESULTS

The intervention group improved the score on Bergs Balance Scale by 2.9 points, which was significantly more than the control group who improved by 1.2 points (p = 0.02). Having exercised 12 times or more was significantly associated with improved strength after intervention (p<0.05). The level of apathy was lower in the exercise group after the intervention, compared to the control group (p = 0.048).

CONCLUSION

The results from our study indicate that a high intensity functional exercise program improved balance and muscle strength as well as reduced apathy in nursing home patients with dementia.

A 52 month follow-up of functional decline in nursing home residents - degree of dementia contributes

Background

Few have studied how personal activities of daily living (P-ADL) develop over time in nursing home residents with dementia. Thus, the aim was to study variables associated with the development of P-ADL functioning over a 52-month follow-up period, with a particular focus on the importance of the degree of dementia.

Method

In all, 932 nursing home residents with dementia (Clinical Dementia Rating–CDR- Scale ≥1) were included in a longitudinal study with four assessments of P-ADL functioning during 52 months. P-ADL was measured using the Lawton and Brody’s Physical Self-Maintenance Scale. Degree of dementia (CDR), neuropsychiatric symptoms and use of psychotropic medication were assessed at the same four time points. Demographic information and information about physical health was included at baseline. Linear regression models for longitudinal data were estimated.

Results

Follow-up time was positively associated with a decline in P-ADL functioning. Degree of dementia at baseline was associated with a decline in P-ADL functioning over time. The association between degree of dementia and P-ADL functioning was strongest at baseline, and then flattened over time. A higher level of neuropsychiatric symptoms such as agitation and apathy and no use of anxiolytics and antidementia medication were associated with a decline in P-ADL functioning at four time points. Higher physical co-morbidity at baseline was associated with a decline in P-ADL functioning.

Conclusion

P-ADL functioning in nursing home patients with dementia worsened over time. The worsening was associated with more severe dementia, higher physical comorbidity, agitation, apathy and no use of anxiolytics and antidementia medication. Clinicians should pay attention to these variables (associates) in order to help the nursing home residents with dementia to maintain their level of functioning for as long as possible.
