An alternative theoretical approach to develop a new conception about pain in people with dementia.

The theoretical approach presented in this paper describes a novel experimental-theoretical methodology to conceptualise pain in people with dementia. Existing procedures for assessment of pain rely on subjective self-report using pain questionnaires and rating scales that have proven to be highly problematic where a person has dementia. Consequently, pain in people with dementia can be undetected and/or undertreated. To address that, we have developed an alternative experimental approach that builds on theoretical and methodological precedents from the arts, humanities and social sciences, for instance, visual thinking strategies, creative thinking or two-step flow of communication. Based on this approach, we designed an experimental workshop setting to ingrate these methodologies to explore pain and its expression in people with dementia. This had led to a new definition of pain as an interruption of the socially mediated process of bodily meaning-making. Furthermore, our experimental methodology could equally well be applied as a training method, where professional staff can intervene into existing implicit meanings and understandings of medical issues. These results emphasise that the future of pain research needs to consider the relational aspects of pain more seriously.

New horizons in hearing conditions.

Hearing conditions such as hearing loss, tinnitus and hyperacusis are highly prevalent in the population and can severely impact communication and quality of life. Hearing is affected by multiple factors, including heredity, noise exposure, age, sex, ear disorders and lifestyle factors. Globally, hearing loss affects over 80% of adults aged 80 years and older, is often experienced in combination with other long-term health conditions and is a mid-life risk factor for dementia. To form a themed collection, we searched Age and Ageing for articles on hearing conditions published from 2000 onwards. This resulted in 22 articles included within the collection. They examined a range of important topics related to hearing healthcare and research, including noise-induced hearing loss, health service quality and safety, psychological and psychosocial consequences of hearing loss and co-morbidities of hearing loss. All articles reported on hearing loss; there were no published articles with a primary focus on other hearing conditions such as tinnitus or hyperacusis, on the health of older people from the Deaf community or on users of Cochlear implants, suggesting key gaps in knowledge and targets for future research. This New Horizons article highlights novel directions in research and practice and takes a forward look at how research into hearing conditions may develop in years to come. It highlights opportunities for the growth of patient-centred research and hearing healthcare supported by the better integration of health and care services as well as cross-speciality working to include common co-morbid health conditions.

Advance care plans in UK care home residents: a service evaluation using a stepped wedge design.

INTRODUCTION: advance care planning (ACP) in care homes has high acceptance, increases the proportion of residents dying in place and reduces hospital admissions in research. We investigated whether ACP had similar outcomes when introduced during real-world service implementation. METHODS: a service undertaking ACP in Lincoln, UK care homes was evaluated using routine data. Outcomes were proportion of care homes and residents participating in ACP; characteristics of residents choosing/declining ACP and place of death for those with/without ACP. Hospital admissions were analysed using mixed-effects Poisson regression for number of admissions, and a mixed-effects negative binomial model for number of occupied hospital bed days. RESULTS: About 15/24 (63%) eligible homes supported the service, in which 404/508 (79.5%) participants chose ACP. Residents choosing ACP were older, frailer, more cognitively impaired and malnourished; 384/404 (95%) residents choosing ACP recorded their care home as their preferred place of death: 380/404 (94%) declined cardiopulmonary resuscitation. Among deceased residents, 219/248 (88%) and 33/49 (67%) with and without advance care plan respectively died in their care home (relative risk 1.35, 95% confidence interval [CI] 1.1-1.6, P < 0.001). Hospital admission rates and bed occupancy did not differ after implementation. DISCUSSION: About 79.5% participants chose ACP. Those doing so were more likely to die at home. Many homes were unwilling or unable to support the service. Hospital admissions were not reduced. Further research should consider how to enlist the support of all homes and to explore why hospital admissions were not reduced.

Are dementia services and support organisations meeting the needs of Lesbian, Gay, Bisexual and Transgender (LGBT) caregivers of LGBT people living with dementia? A scoping review of the literature.

OBJECTIVES: More than 60% of people with dementia live at home, where assistance is usually provided by informal caregivers. Research on the experiences of the Lesbian, Gay, Bisexual and Transgender (LGBT) caregivers is limited. This scoping review of the literature synthesizes international evidence on support provision for the population of LGBT caregivers. METHODS: Eight electronic databases and Google Scholar were searched using terms including 'Dementia', 'LGBT' and 'Caregiver' for all types of articles, including empirical studies, grey literature and sources from charity/third sector/lobbying organisations. Article selection was performed by two raters. Data were analysed through deductive thematic analysis, and three themes were established a priori: Distinct experiences of LGBT caregivers; current barriers to support; strategies to overcome the current challenges. RESULTS: Twenty articles were included. Distinct experiences of LGBT caregivers included a loss of LGBT identity, the impact of historical events, families of choice, and disclosing LGBT identities. Current barriers to support included poor representation of LGBT caregivers in support services, negative attitudes of staff and reluctance of caregivers to seek support. Strategies to overcome the current challenges included staff awareness training and kite-marking inclusion. CONCLUSION: Limited cultural competency of staff and a subsequent reluctance to seek help have an impact on use of support services among LGBT caregivers. Implications for practice include the development of cost-effective, feasible, and acceptable inclusiveness training for services. Implications for policy include implementation in organisations of top-down agendas supporting staff to understand sexuality and non-heteronormative relationships in older age.

How quality improvement collaboratives work to improve healthcare in care homes: a realist evaluation.

BACKGROUND: Quality improvement collaboratives (QICs) bring together multidisciplinary teams in a structured process to improve care quality. How QICs can be used to support healthcare improvement in care homes is not fully understood. METHODS: A realist evaluation to develop and test a programme theory of how QICs work to improve healthcare in care homes. A multiple case study design considered implementation across 4 sites and 29 care homes. Observations, interviews and focus groups captured contexts and mechanisms operating within QICs. Data analysis classified emerging themes using context-mechanism-outcome configurations to explain how NHS and care home staff work together to design and implement improvement. RESULTS: QICs will be able to implement and iterate improvements in care homes where they have a broad and easily understandable remit; recruit staff with established partnership working between the NHS and care homes; use strategies to build relationships and minimise hierarchy; protect and pay for staff time; enable staff to implement improvements aligned with existing work; help members develop plans in manageable chunks through QI coaching; encourage QIC members to recruit multidisciplinary support through existing networks; facilitate meetings in care homes and use shared learning events to build multidisciplinary interventions stepwise. Teams did not use measurement for change, citing difficulties integrating this into pre-existing and QI-related workload. CONCLUSIONS: These findings outline what needs to be in place for health and social care staff to work together to effect change. Further research needs to consider ways to work alongside staff to incorporate measurement for change into QI.

Mild cognitive impairment: the Manchester consensus.

Given considerable variation in diagnostic and therapeutic practice, there is a need for national guidance on the use of neuroimaging, fluid biomarkers, cognitive testing, follow-up and diagnostic terminology in mild cognitive impairment (MCI). MCI is a heterogenous clinical syndrome reflecting a change in cognitive function and deficits on neuropsychological testing but relatively intact activities of daily living. MCI is a risk state for further cognitive and functional decline with 5-15% of people developing dementia per year. However, ~50% remain stable at 5 years and in a minority, symptoms resolve over time. There is considerable debate about whether MCI is a useful clinical diagnosis, or whether the use of the term prevents proper inquiry (by history, examination and investigations) into underlying causes of cognitive symptoms, which can include prodromal neurodegenerative disease, other physical or psychiatric illness, or combinations thereof. Cognitive testing, neuroimaging and fluid biomarkers can improve the sensitivity and specificity of aetiological diagnosis, with growing evidence that these may also help guide prognosis. Diagnostic criteria allow for a diagnosis of Alzheimer's disease to be made where MCI is accompanied by appropriate biomarker changes, but in practice, such biomarkers are not available in routine clinical practice in the UK. This would change if disease-modifying therapies became available and required a definitive diagnosis but would present major challenges to the National Health Service and similar health systems. Significantly increased investment would be required in training, infrastructure and provision of fluid biomarkers and neuroimaging. Statistical techniques combining markers may provide greater sensitivity and specificity than any single disease marker but their practical usefulness will depend on large-scale studies to ensure ecological validity and that multiple measures, e.g. both cognitive tests and biomarkers, are widely available for clinical use. To perform such large studies, we must increase research participation amongst those with MCI.

Social connectedness in adults with mental disorders: ecological validation of a conceptual framework for novel complex interventions.

BACKGROUND: Social connectedness interventions may improve the clinical outcomes and personal recovery of adults with mental disorders but many interventions lack a clear theory-base and show limited effectiveness. AIM: To evaluate the validity of a newly developed conceptual framework (the CIVIC framework: Closeness, Identity, Valued relationships, Involvement and Cared for and accepted) to function as the theory-base for novel social connectedness-based mental health interventions. METHOD: Semi-structured interviews with adults with diagnostically heterogeneous mental disorders (n = 13) and mental health professionals (n = 9). Participants reported their social connectedness experiences, their views on the CIVIC framework and potential targets for new interventions. Sequential inductive and deductive thematic analyses were used. Data quality was assessed through respondent validation. RESULTS: Both inductive and deductive analyses provided validation of the CIVIC framework. Additional themes of Stigma and Connectedness beyond social relationships were identified in the inductive analysis. Candidate interventions to target each CIVIC domain were identified. CONCLUSIONS: The CIVIC framework demonstrates ecological validity and can therefore serve as the theory-base for the development of novel social connectedness-based interventions. This study indicates that interventions would be most effective when they incorporate evidence-based approaches which target each of the categories described by the CIVIC framework.

Changing prevalence and treatment of depression among older people over two decades.

BACKGROUND: Depression is a leading cause of disability, with older people particularly susceptible to poor outcomes. AIMS: To investigate whether the prevalence of depression and antidepressant use have changed across two decades in older people. METHOD: The Cognitive Function and Ageing Studies (CFAS I and CFAS II) are two English population-based cohort studies of older people aged ≥65 years, with baseline measurements for each cohort conducted two decades apart (between 1990 and 1993 and between 2008 and 2011). Depression was assessed by the Geriatric Mental State examination and diagnosed with the Automated Geriatric Examination for Computer-Assisted Taxonomy algorithm. RESULTS: In CFAS I, 7635 people aged ≥65 years were interviewed, of whom 1457 were diagnostically assessed. In CFAS II, 7762 people were interviewed and diagnostically assessed. Age-standardised depression prevalence in CFAS II was 6.8% (95% CI 6.3-7.5%), representing a non-significant decline from CFAS I (risk ratio 0.82, 95% CI 0.64-1.07, P = 0.14). At the time of CFAS II, 10.7% of the population (95% CI 10.0-11.5%) were taking antidepressant medication, more than twice that of CFAS I (risk ratio 2.79, 95% CI 1.96-3.97, P < 0.0001). Among care home residents, depression prevalence was unchanged, but the use of antidepressants increased from 7.4% (95% CI 3.8-13.8%) to 29.2% (95% CI 22.6-36.7%). CONCLUSIONS: A substantial increase in the proportion of the population reporting taking antidepressant medication is seen across two decades for people aged ≥65 years. However there was no evidence for a change in age-specific prevalence of depression.

Developing a model of best practice for teams managing crisis in people with dementia: a consensus approach.

BACKGROUND: Teams delivering crisis resolution services for people with dementia and their carers provide short-term interventions to prevent admission to acute care settings. There is great variation in these services across the UK. This article reports on a consensus process undertaken to devise a Best Practice Model and evaluation Tool for use with teams managing crisis in dementia. METHODS: The Best Practice Model and Tool were developed over a three stage process: (i) Evidence gathering and generation of candidate standards (systematic review and scoping survey, interviews and focus groups); (ii) Prioritisation and selection of standards (consultation groups, a consensus conference and modified Delphi process); (iii) Refining and operationalising standards (consultation group and field-testing). RESULTS: One hundred sixty-five candidate standards arose from the evidence gathering stage; were refined and reduced to 90 through a consultation group exercise; and then reduced to 50 during the consensus conference and weighted using a modified Delphi process. Standards were then operationalised through a clinical consultation group and field-tested with 11 crisis teams and 5 non-crisis teams. Scores ranged from 48 to 92/100. The median score for the crisis teams was 74.5 (range 67-92), and the median score for non-crisis teams was 60 (range 48-72). CONCLUSIONS: With further psychometric testing, this Best Practice Model and Tool will be ideal for the planning, improvement and national benchmarking of teams managing dementia crises in the future.

Giving permission to care for people with dementia in residential homes: learning from a realist synthesis of hearing-related communication.

BACKGROUND: Managing hearing communication for residents living with hearing loss and dementia in long-term care settings is challenging. This paper explores how care can be effective in optimising hearing communication for residents living with dementia. We argue that the underlying notion of permission or authorisation allows care staff to do what they know will be effective in providing person-centred care that enhances hearing communication. The paper also indicates that this notion of permission can usefully be applied to other areas of care home practice. METHODS: To address hearing-related communication in care homes, we conducted a realist synthesis (RS). As a theory-driven approach to reviewing literature, it also uses expert opinion to understand complex health situations. Using RS, we developed a theory surrounding the management of hearing-related communication in care homes. Applying formal processes to the literature search and data extraction, the analysis uncovered relevant mechanisms and contexts to help confirm, refute or refine our understanding of how hearing communication could be improved. RESULTS: Forty-three papers were selected for the realist synthesis. The documents were analysed to construct five context-mechanism-outcome configurations (CMOCs). The CMOCs represent possible care interventions to optimise hearing-related communication in care homes for person living with dementia and hearing loss (PLWDHL). They include leadership promoting positive regard and empathy through person-centred care, communication training for staff, 'knowing the person' and relationship building for responsive awareness of residents' hearing needs, maintaining and monitoring hearing communication through care planning, and managing noise in the care home environment. CONCLUSIONS: Leadership that provides appropriate training and resources is likely to enhance knowledge and skills, leading to staff feeling able and equipped to respond to the hearing-related communication needs of PLWDHL. Collaboration with local hearing services is likely to raise awareness of hearing loss among care home staff. Importantly, care staff require a sense of permission from leadership, to work with knowledge and autonomy in the interest of residents living with dementia and hearing loss.

Measuring health-related quality of life of care home residents: comparison of self-report with staff proxy responses.

INTRODUCTION: care home residents are often unable to complete health-related quality of life questionnaires for themselves because of prevalent cognitive impairment. This study compared care home resident and staff proxy responses for two measures, the EQ-5D-5L and HowRU. METHODS: a prospective cohort study recruited residents ≥60 years across 24 care homes who were not receiving short stay, respite or terminal care. Resident and staff proxy EQ-5D-5L and HowRu responses were collected monthly for 3 months. Weighted kappa statistics and intra-class correlation coefficients (ICCs) adjusted for clustering at the care home level were used to measure agreement between resident and proxies for each time point. The effect of staff and resident baseline variables on agreement was considered using a multilevel mixed effect regression model. RESULTS: 117, 109 and 104 matched pairs completed the questionnaires at 1, 2 and 3 months, respectively. When clustering was controlled for, agreement between resident and staff proxy EQ-5D-5L responses was fair for mobility (ICC: 0.29) and slight for all other domains (ICC ≤ 0.20). EQ-5D Index and Quality-Adjusted Life Year scores (proxy scores higher than residents) showed better agreement than EQ-5D-VAS (residents scores higher than proxy). HowRU showed only slight agreement (ICC ≤ 0.20) between residents and proxies. Staff and resident characteristics did not influence level of agreement for either index. DISCUSSION: the levels of agreement for EQ-5D-5L and HowRU raise questions about their validity in this population.

The individual experience of ageing prisoners: systematic review and meta-synthesis through a Good Lives Model framework.

OBJECTIVE: The existing literature on ageing prisoners tends to focus on such aspects as diagnosis and physical ill-health. In contrast, the experience of imprisonment from the perspective of ageing prisoners has received less attention. Grounded in a Good Lives Model theoretical framework, we reviewed and meta-synthesised literature around their experience of life in prison, its impact on their wellbeing and how prison services are currently addressing their complex needs. We further identify potential areas of improvement. METHODS: 1. Systematic search on Assia, PsycInfo, MedLine, Embase, Web of Science, Google and Gov.uk. 2. Extraction and categorisation of data on NVivo. 3. Development of themes through thematic analysis and meta-synthesis. 4. Identification of potential areas of improvement. RESULTS: We selected 25 studies for our review, of which 13 were from the USA, seven from the UK, two from Australia and one each from Ireland, Switzerland and Israel. We identified three themes: The hardship of imprisonment, addressing health and social care needs, and the route out of prison. CONCLUSIONS: Ageing prisoners have unique and complex health and social care needs which, to varying degree across different countries, are mostly unmet. Promising initiatives to address their needs are emerging, but, at present time, the overall experience of incarceration for the ageing prisoner is quite poor, given the inconsistent physical, emotional and social care support offered from prison intake to release and beyond.

Ageing patients in forensic psychiatric settings: A review of the literature.

OBJECTIVES: The prevalence of ageing patients in forensic psychiatric settings is increasing. However, limited research has reported around this population. The aim of this scoping review is to synthesise the current evidence around ageing forensic psychiatric patients. METHODS: The literature was searched through four databases and Google searches. The identified outputs were screened for suitability and assessed for quality. Quantitative data were extracted and analysed on SPSS; qualitative data were extracted and analysed onto NVivo. RESULTS: Seven studies were included in the review. Quantitative results reported around demographics, service contact, offending patterns, mental, and physical health of ageing patients. Qualitative findings focused on age-friendliness of services, staff-patient rapport, activities, security issues, and discharge planning. CONCLUSIONS: Ageing forensic psychiatric patients present with complex and unique needs in relation to treatment, activities, mental, physical, and support. Further research looking at individual patients' needs is paramount to inform policy development and good practice in this area.

Emotional distress with dementia: A systematic review using corpus-based analysis and meta-ethnography.

OBJECTIVE: More understanding is needed about the emotional experiences of dementia from the perspective of the individual. This understanding can then inform the provision of health care to meet individual needs. This systematic review aimed to present all available descriptions of emotional distress and explanations for emotional distress experienced by individuals with dementia, articulated personally and by others. METHODS: A systematic mixed-method review identified literature that was screened and quality appraised. Data were analysed quantitatively and qualitatively using corpus-based methods and meta-ethnography. RESULTS: The 121 included studies showed that individuals with dementia have expressed emotional distress comprehensibly. Family, professional caregivers, clinicians, and academic writers have also observed and described extreme emotional experiences. Feeling fearful and lonely were predominant and show the importance of anxiety in dementia. Explanations for emotional distress included threats to universal, human needs for identity, belonging, hope, and predictability. CONCLUSIONS: The variable and personal emotional experiences of individuals with dementia are well described and should not continue to be overlooked. Limitations, future research, and clinical implications are discussed.

Feasibility of a staff training and support programme to improve pain assessment and management in people with dementia living in care homes.

OBJECTIVES: The objective of this study was to establish the feasibility and initial effectiveness of training and support intervention for care staff to improve pain management in people with dementia living in care homes (PAIN-Dem). METHODS: PAIN-Dem training was delivered to care staff from three care homes in South London, followed by intervention support and resources to encourage improved pain management by staff over 4 weeks. Feasibility was assessed through fidelity to intervention materials and qualitative approaches. Focus group discussions with staff explored the use of the PAIN-Dem intervention, and interviews were held with six residents and family carers. Pain was assessed in all residents at baseline, 3 and 4 weeks, and goal attainment scaling was assessed at 4 weeks. RESULTS: Delivery of training was a key driver for success and feasibility of the PAIN-Dem intervention. Improvements in pain management behaviour and staff confidence were seen in homes where training was delivered in a care home setting across the care team with good manager buy-in. Family involvement in pain management was highlighted as an area for improvement. Goal attainment in residents was significantly improved across the cohort, although no significant change in pain was seen. CONCLUSIONS: This study shows good initial feasibility of the PAIN-Dem intervention and provides valuable insight into training and support paradigms that deliver successful learning and behaviour change. There is a need for a larger trial of PAIN-Dem to establish its impact on resident pain and quantifiable staff behaviour measures. Copyright © 2017 John Wiley & Sons, Ltd.

Optimal healthcare delivery to care homes in the UK: a realist evaluation of what supports effective working to improve healthcare outcomes.

INTRODUCTION: care home residents have high healthcare needs not fully met by prevailing healthcare models. This study explored how healthcare configuration influences resource use. METHODS: a realist evaluation using qualitative and quantitative data from case studies of three UK health and social care economies selected for differing patterns of healthcare delivery to care homes. Four homes per area (12 in total) were recruited. A total of 239 residents were followed for 12 months to record resource-use. Overall, 181 participants completed 116 interviews and 13 focus groups including residents, relatives, care home staff, community nurses, allied health professionals and General Practitioners. RESULTS: context-mechanism-outcome configurations were identified explaining what supported effective working between healthcare services and care home staff: (i) investment in care home-specific work that legitimises and values work with care homes; (ii) relational working which over time builds trust between practitioners; (iii) care which 'wraps around' care homes; and (iv) access to specialist care for older people with dementia. Resource use was similar between sites despite differing approaches to healthcare. There was greater utilisation of GP resource where this was specifically commissioned but no difference in costs between sites. CONCLUSION: activities generating opportunities and an interest in healthcare and care home staff working together are integral to optimal healthcare provision in care homes. Outcomes are likely to be better where: focus and activities legitimise ongoing contact between healthcare staff and care homes at an institutional level; link with a wider system of healthcare; and provide access to dementia-specific expertise.

Antidepressants for treating depression in dementia.

BACKGROUND: The use of antidepressants in dementia accompanied by depressive symptoms is widespread, but their clinical efficacy is uncertain. This review updates an earlier version, first published in 2002. OBJECTIVES: To determine the efficacy and safety of any type of antidepressant for patients who have been diagnosed as having dementia of any type and depression as defined by recognised criteria. SEARCH METHODS: We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's Specialised Register, on 16 August 2017. ALOIS contains information on trials retrieved from databases and from a number of trial registers and grey literature sources. SELECTION CRITERIA: We included all relevant double-blind, randomised trials comparing any antidepressant drug with placebo, for patients diagnosed as having dementia and depression. DATA COLLECTION AND ANALYSIS: Two review authors selected studies for inclusion and extracted data independently. We assessed risk of bias in the included studies using the Cochrane 'Risk of bias' tool. Where clinically appropriate, we pooled data for treatment periods up to three months and from three to nine months. We used GRADE methods to assess the overall quality of the evidence. MAIN RESULTS: We included ten studies with a total of 1592 patients. Eight included studies reported sufficiently detailed results to enter into analyses related to antidepressant efficacy. We split one study which included two different antidepressants and therefore had nine groups of patients treated with antidepressants compared with nine groups receiving placebo treatment. Information needed to make 'Risk of bias' judgements was often missing.We found high-quality evidence of little or no difference in scores on depression symptom rating scales between the antidepressant and placebo treated groups after 6 to 13 weeks (standardised mean difference (SMD) -0.10, 95% confidence interval (CI) -0.26 to 0.06; 614 participants; 8 studies). There was probably also little or no difference between groups after six to nine months (mean difference (MD) 0.59 point, 95% CI -1.12 to 2.3, 357 participants; 2 studies; moderate-quality evidence). The evidence on response rates at 12 weeks was of low quality, and imprecision in the result meant we were uncertain of any effect of antidepressants (antidepressant: 49.1%, placebo: 37.7%; odds ratio (OR) 1.71, 95% CI 0.80 to 3.67; 116 participants; 3 studies). However, the remission rate was probably higher in the antidepressant group than the placebo group (antidepressant: 40%, placebo: 21.7%; OR 2.57, 95% CI 1.44 to 4.59; 240 participants; 4 studies; moderate-quality evidence). The largest of these studies continued for another 12 weeks, but because of imprecision of the result we could not be sure of any effect of antidepressants on remission rates after 24 weeks. There was evidence of no effect of antidepressants on performance of activities of daily living at weeks 6 to 13 (SMD -0.05, 95% CI -0.36 to 0.25; 173 participants; 4 studies; high-quality evidence) and probably also little or no effect on cognition (MD 0.33 point on the Mini-Mental State Examination, 95% CI -1.31 to 1.96; 194 participants; 6 studies; moderate-quality evidence).Participants on antidepressants were probably more likely to drop out of treatment than those on placebo over 6 to 13 weeks (OR 1.51, 95% CI 1.07 to 2.14; 836 participants; 9 studies). The meta-analysis of the number of participants suffering at least one adverse event showed a significant difference in favour of placebo (antidepressant: 49.2%, placebo: 38.4%; OR 1.55, 95% CI 1.21 to 1.98, 1073 participants; 3 studies), as did the analyses for participants suffering one event of dry mouth (antidepressant: 19.6%, placebo: 13.3%; OR 1.80, 95% CI 1.23 to 2.63, 1044 participants; 5 studies), and one event of dizziness (antidepressant: 19.2%, placebo: 12.5%; OR 2.00, 95% CI 1.34 to 2.98, 1044 participants; 5 studies). Heterogeneity in the way adverse events were reported in studies presented a major difficulty for meta-analysis, but there was some evidence that antidepressant treatment causes more adverse effects than placebo treatment does. AUTHORS' CONCLUSIONS: The available evidence is of variable quality and does not provide strong support for the efficacy of antidepressants for treating depression in dementia, especially beyond 12 weeks. On the only measure of efficacy for which we had high-quality evidence (depression rating scale scores), antidepressants showed little or no effect. The evidence on remission rates favoured antidepressants but was of moderate quality, so future research may find a different result. There was insufficient evidence to draw conclusions about individual antidepressant drugs or about subtypes of dementia or depression. There is some evidence that antidepressant treatment may cause adverse events.

Cholinesterase inhibitors for the treatment of delirium in non-ICU settings.

BACKGROUND: Delirium is a common clinical syndrome defined as alterations in attention with an additional disturbance in cognition or perception, which develop over a short period of time and tend to fluctuate during the course of the episode. Delirium is commonly treated in hospitals or community settings and is often associated with multiple adverse outcomes such as increased cost, morbidity, and even mortality. The first-line intervention involves a multicomponent non-pharmacological approach that includes ensuring effective communication and reorientation in addition to providing reassurance or a suitable care environment. There are currently no drugs approved specifically for the treatment of delirium. Clinically, however, various medications are employed to provide symptomatic relief, such as antipsychotic medications and cholinesterase inhibitors, among others. OBJECTIVES: To evaluate the effectiveness and safety of cholinesterase inhibitors for treating people with established delirium in a non-intensive care unit (ICU) setting. SEARCH METHODS: We searched ALOIS, which is the Cochrane Dementia and Cognitive Improvement Group's Specialised Register, on 26 October 2017. We also cross-checked the reference lists of included studies to identify any potentially eligible trials. SELECTION CRITERIA: We included randomised controlled trials, published or unpublished, reported in English or Chinese, which compared cholinesterase inhibitors to placebo or other drugs intended to treat people with established delirium in a non-ICU setting. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. The primary outcomes were duration of delirium, severity of delirium, and adverse events. The secondary outcomes were use of rescue medications, persistent cognitive impairment, length of hospitalisation, institutionalisation, mortality, cost of intervention, leaving the study early, and quality of life. For dichotomous outcomes, we calculated the risk ratio (RR) with 95% confidence intervals (CIs); for continuous outcomes we calculated the mean difference (MD) with 95% CIs. We assessed the quality of evidence using GRADE to generate a 'Summary of findings' table. MAIN RESULTS: We included one study involving 15 participants from the UK. The included participants were diagnosed with delirium based on the Confusion Assessment Method (CAM) criteria. Eight males and seven females were included, with a mean age of 82.5 years. Seven of the 15 participants had comorbid dementia at baseline. The risk of bias was low in all domains.The study compared rivastigmine with placebo. We did not find any clear differences between the two groups in terms of duration of delirium (MD -3.6, 95% CI -15.6 to 8.4), adverse events (nausea, RR 0.30, 95% CI 0.01 to 6.29), use of rescue medications (RR 0.13, 95% CI 0.01 to 2.1), mortality (RR 0.10, 95% CI 0.01 to 1.56), and leaving the study early (RR 0.88, 95% CI 0.07 to 11.54). Evidence was not available regarding the severity of delirium, persistent cognitive impairment, length of hospitalisation, cost of intervention, or other predefined secondary outcomes.The quality of evidence is low due to the very small sample size. AUTHORS' CONCLUSIONS: There is insufficient evidence to support or refute the use of cholinesterase inhibitors for the treatment of delirium in non-ICU settings. No clear benefits or harms associated with cholinesterase inhibitors were observed when compared with placebo due to the lack of data. More trials are required.

Psychiatric disorders among older prisoners: a systematic review and comparison study against older people in the community.

OBJECTIVES: Despite emerging evidence that older prisoners experience poor mental health, literature in this area is still limited. In the present systematic review and meta-analysis, we report on the prevalence of psychiatric disorders among older prisoners and compare our findings against community studies on older people. METHODS: We searched on Assia, PsycInfo, MedLine, Embase, Web of Science, Google and Gov.uk. We carried out bias assessments, rated studies for quality and ran a heterogeneity test. We meta-analysed prevalence rates of psychiatric disorders through an aggregate weighted mean and calculated relative risk (RR) and statistical significance against community studies. Sensitivity analyses were further performed. RESULTS: We reviewed nine studies and obtained the following prevalence: 'Any psychiatric disorder' 38.4%, depression 28.3%, schizophrenia/psychoses 5.5%, bipolar disorder 4.5%, dementia 3.3%, cognitive impairment 11.8%, personality disorder 22.9%, alcohol abuse 15.9%, anxiety disorders 14.2%, PTSD 6.2%. Older prisoners were found to have higher RR for every single psychiatric disorder against older people in the community, with the sole exception of alcohol abuse (RR = 1) and dementia (RR = .75). The prevalence rates were statistically significantly higher (p < .05) among the prisoners for 'Any psychiatric disorder', depression and personality disorder. Overall, the sensitivity analyses confirmed our original results. CONCLUSION: Our findings point at a high prevalence of every single psychiatric disorder among older prisoners, who also experience rates of dementia and alcohol abuse comparable to those reported in the community. Our results have relevant implications for policy and practice in this area. Further research is crucial to confirm findings from this study.

Patterns and persistence of behavioural and psychological symptoms in those with cognitive impairment: the importance of apathy.

OBJECTIVE: To study the stability and emergence of a range of behavioural and psychological symptoms (BPS), their association with mortality and the effect of covariates on these transitions in a population-based study of cognitively impaired older people with a long follow-up period and large sample size, with a particular focus on apathy. METHODS: Data were from a population-based, longitudinal cohort study of ageing. Interviews were conducted at 0, 2, 6, 8 and 10 years with 3626 participants aged 65+. The persistence of 11 BPS and their association with mortality in those with cognitive impairment (MMSE 25 or below) was investigated using multi-state models, allowing us to take into account estimations of the probability of transitions that occurred in the time between interviews. RESULTS: Most BPS were persistent. Apathy was one of the most stable symptoms; in those with apathy, the probability of still having apathy after 1 year is 62%. Apathy, sleep problems, depression, irritability and wandering were most likely to develop. BPS are associated with mortality; in those with apathy, mortality is 3.1 times more likely than in those without apathy. Low cognitive function and dementia were associated with emergence of new symptoms. CONCLUSIONS: This population-based, multi-centre study with a follow-up period of 10 years showed that BPS are associated with mortality and most symptoms are persistent. Apathy was characterised by a high prevalence, a high persistence and a strong association with mortality, and has a negative impact on disability, management of other disease and caregiver burden.
