A cluster-randomized crossover trial of Montessori activities delivered by family carers to nursing home residents with behavioral and psychological symptoms of dementia.

OBJECTIVES: One-on-one structured Montessori-based activities conducted with people with dementia can improve agitation and enhance engagement. These activities may however not always be implemented by nursing home staff. Family members may present an untapped resource for enabling these activities. This study aimed to evaluate the impact of the Montessori activities implemented by family members on visitation experiences with people who have dementia. DESIGN: Cluster-randomized crossover design. SETTING: General and psychogeriatric nursing homes in the state of Victoria, Australia. PARTICIPANTS: Forty participants (20 residents and 20 carers) were recruited. INTERVENTION: During visits, family members interacted with their relative either through engaging in Montessori-based activities or reading a newspaper (the control condition) for four 30-minute sessions over 2 weeks. MEASUREMENTS: Residents' predominant affect and engagement were rated for each 30-second interval using the Philadelphia Geriatric Center Affect Rating Scale and the Menorah Park Engagement Scale. The Pearlin Mastery Scale was used to rate carers satisfaction with visits. The 15-item Mutuality Scale measured the carers quality of their relationship with the resident. Carers' mood and overall quality of life were measured using the Center for Epidemiological Studies Depression Scale and Carer-QoL questionnaires, respectively. RESULTS: Linear regressions within the generalized estimating equations approach assessed residents' and carers' outcomes. Relative to the control condition, the Montessori condition resulted in more positive engagement (b = 13.0, 95%CI 6.3-19.7, p < 0.001) and affect (b = 0.4, 95%CI 0.2-0.6, p < 0.001) for the residents and higher satisfaction with visits for carers (b = 1.7, 95%CI 0.45-3.00, p = 0.008). No correction was applied to p-values for multiple comparisons. CONCLUSION: This study strengthens the evidence base for the use of the Montessori programs in increasing well-being in nursing home residents. The findings also provide evidence that family members are an additional valuable resource in implementing structured activities such as the Montessori program with residents.

A cluster randomised trial of the program to enhance adjustment to residential living (PEARL): a novel psychological intervention to reduce depression in newly admitted aged care residents.

BACKGROUND: Depression rates are high in residential aged care (RAC) facilities, with newly admitted residents at particular risk. New approaches to address depression in this population are urgently required, particularly psychological interventions suitable for widespread use across the RAC sector. The Program to Enhance Adjustment to Residential Living (PEARL) is a brief intervention, designed to provide individually tailored care approaches to meet the psychological needs of newly admitted residents, delivered in collaboration with facility staff. METHODS: PEARL will be evaluated using a cluster randomised controlled design, comparing outcomes for residents who participate in the intervention with those residing in care as usual control facilities. Participants are RAC residents aged 60 years or above, with normal cognition or mild-moderate cognitive impairment, who relocated to the facility within the previous 4 weeks. The primary outcomes are depressive symptoms and disorders, with secondary outcomes including anxiety, stress, quality of life, adjustment to RAC, and functional dependence, analysed on an intention to treat basis using multilevel modelling. DISCUSSION: PEARL is an intervention based on self-determination theory, designed to reduce depression in newly admitted residents by tailoring day to day care to meet their psychological needs. This simple psychological approach offers an alternative care model to the current over-reliance of antidepressant medications.

Quality indicators of psychotropic prescribing to people with dementia in aged psychiatry inpatient units.

OBJECTIVES: To develop indicators of safe psychotropic prescribing practices for people with dementia and to test them in a convenience sample of six aged mental health services in Victoria, Australia. METHOD: The clinical records of 115 acute inpatients were checked by four trained auditors against indicators derived from three Australian health care quality and safety standards or guidelines. Indicators addressed psychotropic medication history taking; the prescribing of regular and 'as needed' psychotropics; the documentation of psychotropic adverse reactions, and discharge medication plans. RESULTS: The most problematic areas concerned the gathering of information about patients' psychotropic prescribing histories at the point of entry to the ward and, later, the handing over on discharge of information concerning newly prescribed treatments and the reasons for ceasing medications, including adverse reactions. There were wide variations between services. CONCLUSION: The indicators, while drawn from current Australian guidelines, were entirely consistent with current prescribing frameworks and provide useful measures of prescribing practice for use in benchmarking and other quality improvement activities.

A pilot trial of acceptance and commitment therapy for symptoms of depression and anxiety in older adults residing in long-term care facilities.

OBJECTIVES: The aim of this study was to evaluate the efficacy and acceptability of a psychological intervention based on acceptance and commitment therapy (ACT) to improve symptoms of depression and anxiety among older adults living in long-term care. METHOD: Forty one residents aged between 63 and 97 years (M = 85.3 years) participated in this study. Residents were allocated to receive either a 12 session ACT intervention implemented by trainee psychology therapists or a wait-list control group. Measures of depression and anxiety were collected at baseline and 8 week post-intervention, and residents who received the intervention were tracked for three months. A treatment satisfaction questionnaire was administered to residents who received the intervention and a sample of 10 facility staff members. RESULTS: Using an intention to treat approach and controlling for baseline scores, scores on depression measures were significantly lower after the ACT intervention than after the wait-list control. These outcomes were maintained at three-month follow-up. Treatment satisfaction was rated highly by both residents and their care staff. CONCLUSION: This preliminary trial suggests that ACT shows promise as a therapeutic approach to address symptoms of depression in long-term care.

Behavioral Symptoms of Dementia that Present Management Difficulties in Nursing Homes: Staff Perceptions and Their Concordance With Informant Scales.

The current study aimed to profile behaviors associated with dementia that pose management difficulties for staff and determine whether existing rating scales capture these reported behaviors. Staff in 17 nursing homes described the behavioral symptoms of 229 residents with predominantly moderate-severe dementia associated with management difficulties. Behaviors were categorized by an expert clinical panel and compared to items in four dementia behavior rating scales. Staff reported 59 discrete behavioral symptoms, with physically agitated, aggressive verbal, non-aggressive verbal, and aggressive physical behaviors most common, followed by resistance to care and inappropriate social and sexual behaviors. Results suggested that some scales omit important behaviors reported by staff for residents with particularly challenging behaviors. The current study highlights the clinical complexity faced by nursing home staff in managing residents with behavioral symptoms of dementia. [Journal of Gerontological Nursing, 43(1), 34-43.].

Alfentanil anesthetic augmentation lengthens seizure duration in electroconvulsive therapy with older people.

Electroconvulsive therapy (ECT) prescription rates rise with age, making it important that treatments be made as effective and safe as possible (Plakiotis et al., 2012). Older people are vulnerable to post-treatment confusion and to subsequent deficits in attention, new learning, and autobiographical memory (Gardner and O'Connor, 2008). Strategies to minimize cognitive side-effects include unilateral electrode placement and stimulus dose titration whereby electrical charge is individually calibrated to seizure threshold (Sackeim et al., 2000). It remains the case, however, that threshold levels typically rise over the treatment course, leading to an increase both in delivered charge and the risk of adverse sequelae.

The Clinical and Service Outcomes of Unilateral and Bilateral ECT Electrode Placements in Australian Aged Psychiatry Services.

OBJECTIVE: The aim of the study was to determine whether depressed aged inpatients treated with brief pulse unilateral electroconvulsive therapy (ECT) differed from those treated with bilateral (bitemporal or bifrontal) ECT with respect to numbers of treatments, length of hospital admission, changes in scores on depression and cognitive scales, and serious adverse effects. METHODS: An audit of routinely collected data regarding 221 acute ECT courses in 7 public aged psychiatry services in Victoria, Australia. RESULTS: Patients given unilateral, bifrontal, and bitemporal treatments were similar with respect to personal, clinical, and treatment characteristics. Most treatments were administered in line with local clinical guidelines and were rated as effective. Psychiatrists preferred unilateral ECT in the first instance with stimulus dosing based on patients' seizure thresholds. Approximately a quarter of unilateral courses were switched later to bitemporal placement, most probably because of insufficient progress. Bilateral treatments were associated with a larger number of treatments, less improvement in scores on mood and cognitive scales, and more refusals to continue treatment than unilateral-only ECT. DISCUSSION: Brief pulse unilateral ECT proved more effective than bitemporal and bifrontal ECT for most aged patients, especially when coupled with stimulus dosing based on seizure threshold.

A personalized multimedia device to treat agitated behavior and improve mood in people with dementia: A pilot study.

Agitated behaviors and dysphoric moods in nursing home residents with dementia may be a response to a lack of personalized, meaningful activity and stimulation. To address this deficiency, a personal computer was adapted to play favorite music and display photographs, movies and messages that were selected or made by family members. The system (called Memory Box) is accompanied by a simplified interface to help people with dementia access material independently. The system's ability to reduce agitation, and improve symptoms of depression and anxiety, was tested by means of an eight-week randomized, single-blinded, cross-over trial comparing Memory Box with a control condition that offered equivalent contact with research staff. Eleven nursing home residents with mild to severe dementia and persistent, daily agitated behaviors completed the study. Outcome measures included ratings of anxiety, depression and agitated behavior made by knowledgeable staff members in collaboration with researchers. Memory Box was well utilized and highly rated by residents, families and staff members. There were significant reductions in depressive and anxiety symptoms during the course of the intervention. The system shows promise as a tool to assist families and nursing home staff to improve the wellbeing of cognitively impaired older people with agitated behaviors.

Validity of the geriatric depression scale and the collateral source version of the geriatric depression scale in nursing homes.

BACKGROUND: Depression is a common psychiatric disorder in older people. The study aimed to examine the screening accuracy of the Geriatric Depression Scale (GDS) and the Collateral Source version of the Geriatric Depression Scale (CS-GDS) in the nursing home setting. METHODS: Eighty-eight residents from 14 nursing homes were assessed for depression using the GDS and the CS-GDS, and validated against clinician diagnosed depression using the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR Axis I Disorders (SCID) for residents without dementia and the Provisional Diagnostic Criteria for Depression in Alzheimer Disease (PDCdAD) for those with dementia. The screening performances of five versions of the GDS (30-, 15-, 10-, 8-, and 4-item) and two versions of the CS-GDS (30- and 15-item) were analyzed using receiver operating characteristic (ROC) curves. RESULTS: Among residents without dementia, both the self-rated (AUC = 0.75-0.79) and proxy-rated (AUC = 0.67) GDS variations performed significantly better than chance in screening for depression. However, neither instrument adequately identified depression among residents with dementia (AUC between 0.57 and 0.70). Among the GDS variations, the 4- and 8-item scales had the highest AUC and the optimal cut-offs were >0 and >3, respectively. CONCLUSIONS: The validity of the GDS in detecting depression requires a certain level of cognitive functioning. While the CS-GDS is designed to remedy this issue by using an informant, it did not have adequate validity in detecting depression among residents with dementia. Further research is needed on informant selection and other factors that can potentially influence the validity of proxy-based measures in the nursing home setting.

Deprescribing psychotropic medications in aged care facilities: the potential role of family members.

There is widespread concern in Australia and internationally at the high prevalence of psychotropic medication use in residential aged care facilities. It is difficult for nurses and general practitioners in aged care facilities to cease new residents' psychotropic medications when they often have no information about why residents were started on the treatment, when and by whom and with what result. Most existing interventions have had a limited and temporary effect and there is a need to test different strategies to overcome the structural and practical barriers to psychotropic medication cessation or deprescribing. In this chapter, we review the literature regarding psychotropic medication deprescribing in aged care facilities and present the protocol of a novel study that will examine the potential role of family members in facilitating deprescribing. This project will help determine if family members can contribute information that will prove useful to clinicians and thereby overcome one of the barriers to deprescribing medications whose harmful effects often outweigh their benefits. We wish to understand the knowledge and attitudes of family members regarding the prescribing and deprescribing of psychotropic medications to newly admitted residents of aged care facilities with a view to developing and testing a range of clinical interventions that will result in better, safer prescribing practices.

Personalized one-to-one intervention in agitated individuals with dementia: responders versus non-responders.

The aim of the current study was to explore why some individuals with dementia and agitated behavior showed limited response to a personalized intervention. Ten consistently agitated individuals (i.e., non-responders) were compared with 34 individuals who were more settled during the intervention (i.e., responders). Most participants had severe cognitive deficits; however, non-responders were more impaired. Where responders showed large improvements across conditions, agitated behavior remained equally high in non-responders. Responders and non-responders showed increased interest and engagement during the intervention. Increased agitated behavior was associated with severe cognitive impairment. Although studies have shown that psychosocial interventions can reduce agitated behavior, there does seem to be a point where it becomes more difficult to reduce this behavior. However, non-responders still displayed interest, and the authors believe further personalization of the intervention is possible. Therefore, severe dementia and agitated behavior should not exclude individuals from psychosocial interventions; however, a more detailed and timely implementation plan of such treatments may be warranted.

Methodological challenges in studies of bright light therapy to treat sleep disorders in nursing home residents with dementia.

AIM: Numerous studies have explored the effectiveness of bright light therapy as a treatment of sleep disorders in nursing home and long-stay geriatric hospital residents, most of whom have dementia. A recent Cochrane Collaboration meta-analysis of 10 selected studies concluded that there was insufficient evidence to assess its therapeutic efficacy as most available studies had methodological problems. We sought to remedy this situation by developing proposals to guide research methods in future studies. METHODS: Based on the literature and our own clinical and research experience, we developed a series of proposals relating to study design, participant selection, light delivery modalities and outcome measures that we believe will maximize the chances of identifying a bright light treatment effect. We then checked adherence to these proposals in all relevant published experimental studies. RESULTS: Of the 18 studies published in the last two decades that met our selection criteria, only half the studies had selected participants with a sleep disorder. Eleven studies excluded people with severe vision loss; seven included a clinical rating of sleep, and five measured baseline lighting levels. Most checked psychoactive medication prescriptions but few reported changes in prescriptions over the course of the study. Most also checked treatment adherence and included some control for differences in amount of social contact. CONCLUSIONS: Evidence for the effectiveness of bright white light treatment in people residing in nursing homes is equivocal. We anticipate that the quality of this evidence will be improved if researchers refine their study methods and adopt a more uniform approach.

Are reports of cognitive testing among older electroconvulsive therapy recipients clinically valid?

OBJECTIVES: Electroconvulsive therapy (ECT) administration rises in frequency with age, with older depressed adults often showing clinical features predictive of good response. Recent reviews suggest that older people experience few if any long-term cognitive adverse effects after contemporary ECT, despite their increased vulnerability to these. However, the broader clinical validity of research findings is not assured as most studies of ECT-related cognitive effects do not discuss cognitive test nonparticipants. This study examines whether cognitive test participants and nonparticipants are comparable. METHODS: We recently completed a study of cognition in depressed patients 65 years and older treated with ECT. Only 35% of eligible patients completed neuropsychological testing at 2 time points, the remainder either refusing or unable to consent. To examine whether exclusion of most eligible patients from cognitive testing might have affected the clinical applicability of findings, we compared demographic and clinical characteristics of patients who participated with those who did not based on a subset of patients from our original study. RESULTS: The 2 patient groups differed in several respects. Most notably, nonparticipants were significantly more likely to be involuntary patients; to refuse food and fluids; and to require treatment with a bitemporal or mixed electrode placement. CONCLUSIONS: Our findings suggest cognitive test nonparticipants to be more severely psychiatrically unwell than test participants. As their exclusion might bias results and confound understanding of this important ECT-related topic, special mention of participation rates and comparison of participants and nonparticipants is recommended to establish the clinical relevance of future study findings.

Comparison of family satisfaction in Australian ethno-specific and mainstream aged care facilities.

The aim in this study was to identify specific aspects of care that increased satisfaction of family members of Greek and Italian residents with dementia in mainstream or ethno-specific aged care facilities in Australia. Relatives of 83 aged care residents with Greek or Italian backgrounds who were also cognitively impaired were interviewed. They rated their satisfaction with the facility and suggested improvements regarding the care provided. Family members with relatives in ethno-specific care were more satisfied, in terms of the facility's ability to meet the resident's language and cultural needs, social/leisure activities, and the food provided. The presence of a bilingual staff member and greater perceived reduction in family caregiver stress upon admission were associated with higher satisfaction. Results implicate the role of activities programs, catering, resident interaction, supporting caregivers upon admission, and bilingual staff members to increase family satisfaction, with the potential to improve the care provided to residents in mainstream care.

The feasibility of volunteers facilitating personalized activities for nursing home residents with dementia and agitation.

BACKGROUND: Nursing home residents' behavioral and psychological symptoms of dementia are often exacerbated by a lack of social contact and meaningful activity. Volunteers might assist in addressing this deficiency but they are often discouraged by staff from engaging with residents with challenging behaviors. As a result, some of the neediest residents receive the least social and psychological support. AIM: This project explored the implementation of personalized, one-to-one activities by nursing home volunteers to determine if volunteers were able and willing to complete a training program and undertake activities with residents with dementia and challenging behaviors. METHODS: 19 nursing home volunteers in Melbourne, Australia, were trained to apply Montessori-type personalized activities with a selected resident whose dementia was complicated by a frequent, non-aggressive agitated behavior. The volunteers were asked to attend a workshop and pay six 30-min visits to the resident over a three week period. They completed knowledge and attitude rating scales before and after the intervention and were interviewed afterward regarding their experiences and perceptions. RESULTS: 16 volunteers completed the program and eight met or exceeded every study requirement. Most of them derived satisfaction from engaging residents' interest and were pleased to learn new skills. The scores on the dementia knowledge and attitude rating scale of those who completed the visits were higher at the study's outset than the scores of those who failed to make any visits. CONCLUSIONS: It is certainly feasible to train volunteers to work with residents who might otherwise be isolated. It is important to demonstrate activities to volunteers at the outset and to provide them with careful, ongoing supervision and support. Notwithstanding some difficulties and challenges, volunteers represent a growing and hitherto untapped pool of support for people with dementia and complex needs.

A literature review of spaced-retrieval interventions: a direct memory intervention for people with dementia.

BACKGROUND: With the increasing prevalence of dementia, there is a pressing need to identify effective interventions that prolong independent functioning. As pharmacological interventions aimed at slowing cognitive decline have been found to have a number of limitations, research has now moved toward studying complementary non-pharmacological cognitive training interventions. This review describes the use of spaced-retrieval as a method to teach new information and reduce behavioral problems in people with dementia. METHODS: We searched the databases PsychINFO, MEDLINE, and Scopus as well as reference lists of relevant papers to identify articles describing the use of spaced-retrieval with people with dementia. Only primary, peer-reviewed research published in English was included in this review. RESULTS: In total, 34 studies were identified, three of which were randomized controlled trials. We found that across studies, there was wide variability with regard to design, methodology, and outcome measures used. Nonetheless, the existing research demonstrates that spaced-retrieval training can be successfully used to teach people with dementia new and previously known face- and object-name associations, as well as cue-behavior associations aimed at alleviating problem behaviors and improving functional skills. The method can also assist with the recollection of past events. CONCLUSIONS: Current evidence indicates that spaced-retrieval training is effective in enabling people with dementia to learn new information and behavioral strategies. Future research should attempt to address the limitations outlined in this review and focus on utilizing this technique to achieve more functional and clinically relevant outcomes. Recommendations are also made with regard to investigating potential secondary benefits of spaced-retrieval and strengthening study design.

A randomized crossover trial to study the effect of personalized, one-to-one interaction using Montessori-based activities on agitation, affect, and engagement in nursing home residents with Dementia.

BACKGROUND: Increasingly more attention has been paid to non-pharmacological interventions as treatment of agitated behaviors that accompany dementia. The aim of the current study is to test if personalized one-to-one interaction activities based on Montessori principles will improve agitation, affect, and engagement more than a relevant control condition. METHODS: We conducted a randomized crossover trial in nine residential facilities in metropolitan Melbourne, Australia (n = 44). Personalized one-to-one activities that were delivered using Montessori principles were compared with a non-personalized activity to control for the non-specific benefits of one-to-one interaction. Participants were observed 30 minutes before, during, and after the sessions. The presence or absence of a selected physically non-aggressive behavior was noted in every minute, together with the predominant type of affect and engagement. RESULTS: Behavior counts fell considerably during both the Montessori and control sessions relative to beforehand. During Montessori activities, the amount of time spend actively engaged was double compared to during the control condition and participants displayed more positive affect and interest as well. Participants with no fluency in English (all from non-English speaking backgrounds) showed a significantly larger reduction in agitation during the Montessori than control sessions. CONCLUSION: Our results show that even non-personalized social contact can assist in settling agitated residents. Tailoring activities to residents' needs and capabilities elicit more positive interactions and are especially suitable for people who have lost fluency in the language spoken predominantly in their residential facility. Future studies could explore implementation by family members and volunteers to avoid demands on facilities' resources.

A study protocol to investigate the management of depression and challenging behaviors associated with dementia in aged care settings.

BACKGROUND: The high occurrence and under-treatment of clinical depression and behavioral and psychological symptoms of dementia (BPSD) within aged care settings is concerning, yet training programs aimed at improving the detection and management of these problems have generally been ineffective. This article presents a study protocol to evaluate a training intervention for facility managers/registered nurses working in aged care facilities that focuses on organisational processes and culture as well as knowledge, skills and self-efficacy. METHODS: A Randomised Control Trial (RCT) will be implemented across 18 aged care facilities (divided into three conditions). Participants will be senior registered nurses and personal care attendants employed in the aged care facility. The first condition will receive the training program (Staff as Change Agents - Enhancing and Sustaining Mental Health in Aged Care), the second condition will receive the training program and clinical support, and the third condition will receive no intervention. RESULTS: Pre-, post-, 6-month and 12-month follow-up measures of staff and residents will be used to demonstrate how upskilling clinical leaders using our transformational training approach, as well as the use of a structured screening, referral and monitoring protocol, can address the mental health needs of older people in residential care. CONCLUSIONS: The expected outcome of this study is the validation of an evidence-based training program to improve the management of depression and BPSD among older people in residential care settings by establishing routine practices related to mental health. This relatively brief but highly focussed training package will be readily rolled out to a larger number of residential care facilities at a relatively low cost.

A randomized, controlled cross-over trial of dermally-applied lavender (Lavandula angustifolia) oil as a treatment of agitated behaviour in dementia.

BACKGROUND: Lavender essential oil shows evidence of sedative properties in neurophysiological and animal studies but clinical trials of its effectiveness as a treatment of agitation in people with dementia have shown mixed results. Study methods have varied widely, however, making comparisons hazardous. To help remedy previous methodological shortcomings, we delivered high grade lavender oil in specified amounts to nursing home residents whose agitated behaviours were recorded objectively. METHODS: 64 nursing home residents with frequent physically agitated behaviours were entered into a randomized, single-blind cross-over trial of dermally-applied, neurophysiologically active, high purity 30% lavender oil versus an inactive control oil. A blinded observer counted the presence or absence of target behaviours and rated participants' predominant affect during each minute for 30 minutes prior to exposure and for 60 minutes afterwards. RESULTS: Lavender oil did not prove superior to the control oil in reducing the frequency of physically agitated behaviours or in improving participants' affect. CONCLUSIONS: Studies of essential oils are constrained by their variable formulations and uncertain pharmacokinetics and so optimal dosing and delivery regimens remain speculative. Notwithstanding this, topically delivered, high strength, pure lavender oil had no discernible effect on affect and behaviour in a well-defined clinical sample.

Responding to the death of a resident in aged care facilities: perspectives of staff and residents.

A qualitative study using individual semistructured interviews was undertaken to explore the perceptions and experiences of 23 aged care residents with mild dementia concerning the deaths of coresidents. The views of 25 facility staff members were also explored. The study was based in 3 aged residential facilities in Victoria, Australia. Interview data indicated that residents and staff had differing views. Residents reported that the impact of the death of a coresident was much less than staff members thought. Residents generally wanted to be told about the death of someone they knew and considered attempts to hide the death and the removal of the body both unnecessary and disrespectful. Both groups agreed that the celebration of the life of a resident was important, although they differed in their preferences for the way this is done. These findings have implications for staff education and practice.
