Association of Antidementia Drugs and Mortality in Community-Dwelling Frail Older Patients With Dementia: The Role of Mortality Risk Assessment

Objective

To evaluate whether treatment with antidementia drugs is associated with reduced mortality in older patients with different mortality risk at baseline.

Use of Antipsychotic Drugs Among Residents With Dementia in European Long-Term Care Facilities: Results From the SHELTER Study

BackgroundBehavioral and psychological symptoms of dementia (BPSD) are common reasons for use of antipsychotic drugs among older individuals with dementia. These drugs are not approved for such use and both the Food and Drug Administration and European Medicines Agency have issued warnings to limit such use.ObjectivesThis study aimed to describe patterns of antipsychotic drug use in a sample of nursing home residents with dementia in 7 European countries and Israel.DesignThis cross-sectional, retrospective cohort study used data from the SHELTER study that collected comprehensive resident data using the interRAI Long-Term Care Facility instrument.MethodsFifty-seven long-term care facilities participated from 8 countries, and the sample included 4156 long-term care residents from these settings. Individuals with dementia, both Alzheimer and non-Alzheimer types, were identified. Potential correlates of any antipsychotic and atypical versus conventional antipsychotic drug use among residents with dementia were identified using generalized estimation equation modeling.ResultsA total of 2091 individuals with dementia were identified. Antipsychotic drug use among these individuals varied by country, with overall prevalence of use being 32.8% (n = 662). Among antipsychotic users, 7 in 10 were receiving atypical agents. Generalized estimation equation analysis revealed that the strongest correlate of any antipsychotic drug use was severe behavioral symptoms, which increased the likelihood by 2.84. Correlates of atypical versus conventional antipsychotic drug use included psychiatric services, more than 10 medications, moderate behavioral symptoms, and female gender.ConclusionDespite recommendations to avoid the use of antipsychotic drugs in patients with dementia, a large proportion of residents in European long-term care facilities continue to receive such agents. Future work should not only establish the appropriateness of such use through outcomes studies, but explore withdrawal strategies as well as alternative treatment modalities.     

Effectiveness of Mealtime Interventions on Behavior Symptoms of People With Dementia Living in Care Homes: A Systematic Review

ObjectiveElderly residents with dementia commonly exhibit increased agitation at mealtimes. This interferes with eating and can be distressing for both the individual and fellow residents. This review examines the effectiveness of mealtime interventions aimed at improving behavioral symptoms in elderly people living with dementia in residential care.DesignSystematic review.Data sourcesMedline, PsycINFO, Embase, HMIC, AMED (OvidSP); CDSR, CENTRAL, DARE (Cochrane Library, Wiley); CINAHL (EBSCOhost); British Nursing Index (NHS Evidence); ASSIA (ProQuest); Social Science Citation Index (Web of Knowledge); EThOS (British Library); Social Care Online and OpenGrey from inception to November 2012. Forward and backward citation chases, hand searches of other review articles identified in the search, and key journals.Types of studyAll comparative studies were included. Articles were screened for inclusion independently by 2 reviewers. Data extraction and quality appraisal were performed by one reviewer and checked by a second with discrepancies resolved by discussion with a third if necessary. Data were not suitable for meta-analysis so narrative synthesis was carried out.ResultsA total of 6118 articles were identified in the original search. Eleven articles were finally included. Mealtime interventions were categorized into 4 types: music, changes to food service, dining environment alteration, and group conversation. Study quality was poor, making it difficult to reach firm conclusions. Although all studies showed a trend in favor of the intervention, only 6 reported a statistically significant improvement in behavioral symptoms. Four studies suggest cumulative or lingering effects of music on agitated and aggressive behaviors.ConclusionThere is some evidence to suggest that mealtime interventions improve behavioral symptoms in elderly people with dementia living in residential care, although weak study designs limit the generalizability of the findings. Well designed, controlled trials are needed to further understand the utility of mealtime interventions in this setting.     

The Negative Impact of Psychotropic Drug Use on Quality of Life in Nursing Home Patients at Different Stages of Dementia: Cross-Sectional Analyses from the COSMOS Trial

ObjectivesThe quality of life (QoL) in nursing home (NH) patients with dementia is threatened by neuropsychiatric symptoms. This may trigger the use of psychotropic drugs, yet it is unknown if this practice improves the QoL. We investigated the association between the number of psychotropic drugs and QoL at different stages of dementia, adjusted for neuropsychiatric symptoms.DesignCross-sectional analysis of baseline data from the COSMOS study, a multicenter, cluster-randomized, single-blinded, controlled trial.Setting and ParticipationFour hundred thirty-one patients (aged ≥65 years) with and without dementia from 33 Norwegian NHs comprising 67 wards.MeasuresQoL assessed by Quality of Life in Late Stage Dementia (QUALID) and Quality of Life in Dementia (QUALIDEM), neuropsychiatric symptoms by Neuropsychiatric Inventory–Nursing Home version, and cognition by Mini-Mental State Examination.ResultsAt least 1 psychotropic drug was prescribed to 71% of the 431 participants included in the final sample. We estimated the trend in mean QoL scores over the number of psychotropic drugs in patients with clinical significant neuropsychiatric symptom load. QoL assessed by QUALID and QUALIDEM decreased by increasing number of psychotropic drugs (P < .001). No psychotropic drugs (mean QUALID score 20 ± 0.5, mean QUALIDEM score 40 ± 8.1) compared to ≥3 psychotropic drug (mean QUALID score 25 ± 7.8, mean QUALIDEM score 33 ± 8.0). This association was evident in mild, moderate, and severe dementia but absent in people without dementia. Use of antidepressant agents in mild and moderate dementia was associated with increased QoL compared with no use of antidepressant agents.Conclusions and ImplicationsOverall, our findings suggest that psychotropic drugs might pose a threat to QoL in NH patients at all stages of dementia, possibly with the exception of use of antidepressant agents in mild to moderate dementia. This underlines the need for updated knowledge on psychopharmacologic treatment and implementation of procedures for maintaining QoL in dementia care facilities.     

Costs of Care of Agitation Associated With Dementia in 8 European Countries: Results From the RightTimePlaceCare Study

Objective

Psychotropic Drugs in Patients With Alzheimer's Disease: A Longitudinal Study by the Registry of Dementias of Girona (ReDeGi) in Catalonia,Spain

ObjectivesPsychotropic drugs are usually prescribed to deal with behavioral and psychological symptoms of dementia, especially when nonpharmacologic approaches are not available or have limited efficacy. Poor outcomes and serious adverse events of the drugs used must be addressed, and risk-benefit ratios need to be considered. The aim of this longitudinal study was to describe the evolution of dispensation of psychotropic drugs in patients with Alzheimer's disease (AD) and to identify the associated demographic and clinical variables.MethodsLongitudinal study using 698 cases with AD included in the Registry of Dementias of Girona in 2007 and 2008 and followed up during 3 years. Drugs were categorized according to the Anatomical Therapeutic Chemical classification. Binary logistic regression analyses were used to detect the variables associated with the use of antipsychotics, selective serotonin reuptake inhibitors (SSRIs), anxiolytics, and hypnotics.ResultsOf the patients, 51.2% consumed antipsychotics at least once during the three years of the study, whereas 73.3% and 58.2% consumed SSRIs and anxiolytics, respectively; 32.8% used hypnotics. Antipsychotic use was associated with a diagnosis of AD with delusions) [odds ratio (OR) = 5.7] and with increased behavior disorders (OR = 1.2). Patients with AD with depressed mood were more likely to be treated with SSRIs (OR = 3.1), while being a woman was associated with increased dispensation of anxiolytics (OR = 1.9) and SSRIs (OR = 2.2).ConclusionsConsumption of psychotropic drugs by the patients with AD registered in the Registry of Dementias of Girona is very high. Despite all the described adverse effects and recommendations of caution in their use, antipsychotics still are extensively used.     

Dietary Patterns and the Risk of Inflammatory Bowel Disease: Findings from a Case-Control Study

Scientific evidence shows that dietary patterns are associated with the risk of IBD, particularly among unhealthy and Western dietary patterns. However, Western dietary patterns are not exclusive to Western countries, as Jordanians are steadily moving towards a Western lifestyle, which includes an increased consumption of processed foods. This study aims to investigate the association between dietary patterns and the risk factors for IBD cases among Jordanian adults. This case-control study was conducted between November 2018 and December 2019 in the largest three hospitals in Jordan. Three hundred and thirty-five Jordanian adults aged between 18–68 years were enrolled in this study: one hundred and eighty-five IBD patients who were recently diagnosed with IBD (n = 100 for ulcerative colitis (UC) and n = 85 for Crohn’s disease (CD)) and 150 IBD-free controls. Participants were matched based on age and marital status. In addition, dietary data was collected from all participants using a validated food frequency questionnaire. Factor analysis and principal component analysis were used to determine the dietary patterns. Odds ratios (OR) and their 95% confidence interval (CI) were calculated using a multinomial logistic regression model. Two dietary patterns were identified among the study participants: high-vegetable and high-protein dietary patterns. There was a significantly higher risk of IBD with high-protein intake at the third (OR, CI: 2.196 (1.046–4.610)) and fourth (OR, CI: 4.391 (2.67–8.506)) quartiles in the non-adjusted model as well as the other two adjusted models. In contrast, the high-vegetable dietary pattern shows a significant protective effect on IBD in the third and fourth quartiles in all the models. Thus, a high-vegetable dietary pattern may be protective against the risk of IBD, while a high-protein dietary pattern is associated with an increased risk of IBD among a group of the Jordanian population.     

Treatment of Hypertension in People With Dementia: A Multicenter Prospective Observational Cohort Study

ObjectivesTo describe the treatment of hypertension in people with dementia and collate evidence on adverse health events whilst on treatment.DesignA multicenter prospective observational cohort study.Setting and participantsPeople with documented diagnoses of hypertension and dementia were recruited through memory clinics and general practice from 8 sites in the United Kingdom.MethodsThe cohort was recruited between July 2013 and October 2014. Participants underwent face-to-face, standardized assessment of blood pressure (BP), activities of daily living, cognitive function, and medication use. Follow-up was by monthly telephone interview for 6 months to collate data on adverse health events.Results181 participants were recruited and 177 followed up; 126 (70%) were female, mean age was 82 [standard deviation (SD) 6.3] years, median Mini-Mental State Examination score was 23 [interquartile range (IQR) 18-26] and mean BP was 141/78 (SD 22/12) mmHg. Antihypertensive drugs were prescribed in 157 (87%). Participants were prescribed a median of 1 (IQR 1-2) antihypertensive medication. Angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers were the most frequently prescribed antihypertensives in 63% of participants. Target BP was achieved in 58% (95% confidence interval 49%-64%). Increasing number of antihypertensives was not associated with lower systolic or diastolic BP, or with a higher proportion of patients attaining target BP. Participants had 214 falls, 3 had a fracture, 3 developed symptomatic heart failure, 4 had cerebrovascular events, and 8 died.Conclusions/ImplicationsIn this population of people with mild dementia, participants were treated with standard antihypertensive medications in a similar proportion to the general population, with a similar proportion achieving target BP. The rate of adverse health events was higher than in randomized controlled trials of antihypertensives and raises reservations about the assumptions underpinning antihypertensive treatment in people with dementia. These findings may help inform clinical decision making.     

Body-Mass Index and Mortality in Incident Dementia: A Cohort Study on 11,398 Patients From SveDem,the Swedish Dementia Registry

BackgroundBody mass index (BMI) is used worldwide as an indirect measure of nutritional status and has been shown to be associated with mortality. Controversy exists over the cut points associated with lowest mortality, particularly in older populations. In patients suffering from dementia, information on BMI and mortality could improve decisions about patient care.ObjectivesThe objective was to explore the association between BMI and mortality risk in an incident dementia cohort.DesignCohort study based on SveDem, the Swedish Quality Dementia Registry; 2008–2011.SettingSpecialist memory clinics, Sweden.ParticipantsA total of 11,398 patients with incident dementia with data on BMI (28,190 person-years at risk for death).Main outcome measuresHazard ratios and 95% confidence intervals for mortality associated with BMI were calculated, controlling for age, sex, dementia type, results from Mini-Mental State Examination, and number of medications. BMI categories and linear splines were used.ResultsHigher BMI was associated with decreased mortality risk, with all higher BMI categories showing reduced risk relative to patients with BMI of 18.5 to 22.9 kg/m², whereas underweight patients (BMI <18.5 kg/m²) displayed excess risk. When explored as splines, increasing BMI was associated with decreased mortality risk up to BMI of 30.0 kg/m². Each point increase in BMI resulted in an 11% mortality risk reduction in patients with BMI less than 22.0 kg/m², 5% reduction when BMI was 22.0 to 24.9 kg/m², and 3% risk reduction among overweight patients. Results were not significant in the obese weight range. Separate examination by sex revealed a reduction in mortality with increased BMI up to BMI 29.9 kg/m² for men and 24.9 kg/m² for women.ConclusionHigher BMI at the time of dementia diagnosis was associated with a reduction in mortality risk up to and including the overweight category for the whole cohort and for men, and up to the normal weight category for women.     

Depression in People With Dementia and Caregiver Outcomes: Results From the European Right Time Place Care Study

ObjectiveTo investigate the cross-sectional associations between depression in people with dementia and both caregiver burden and quality of life in 8 European countries, and to test these associations compared with the presence of other neuropsychiatric symptoms.DesignCross-sectional study.Setting and ParticipantsIn total, 1223 dyads comprised of informal caregivers and people with dementia living in a community-dwelling setting, recruited from the Right Time Place Care study, a cohort survey from 8 European countries.MeasuresTo test the associations between depression (according to the Cornell Scale for Depression in Dementia) and informal caregiver burden (defined by the Zarit scale and hours of supervision in terms of Resource Utilization in Dementia), distress (defined by the Neuropsychiatric Inventory Questionnaire distress score), and quality of life (according to the visual analogue scale and 12-item General Health Questionnaire).ResultsLinear regressions showed an association between depression and main outcomes (Zarit scale: β 3.7; P = .001; hours of supervision: β 1.7; P = .004; Neuropsychiatric Inventory Questionnaire distress score: β 1.2; P = .002). A similar association was found concerning psychological and overall well-being (12-item General Health Questionnaire: β 1.8; P < .001; Euroqol Visual Analogue Scale: β −4.1; P = .003). Both associations remained significant despite the presence of other NPS and after adjusting for confounders.Conclusions and ImplicationsFurther studies are needed to assess whether providing tailored strategies for optimizing diagnosis and managing of depression in people with dementia might improve caregiver quality of life and reduce their burden in the community-dwelling setting.     

Integrating the Financing and Delivery of Medical and Supportive Services for People Living With Dementia

The number of people living with dementia (PLWD) is expected to grow considerably in the coming years. PLWD often have substantial medical and supportive service needs and face fragmentation of services across payers and across health and social service systems; recently, efforts have been made to achieve greater integration of care and financing. This article considers issues related to integrating long-term services and supports (LTSS), medical care, and financing for PLWD; reviews the policy context and key clinical and delivery system challenges to these efforts; and describes key lessons regarding integration learned from examples in the field. Recommendations are provided and include the following: (1) assess carefully whether integration of medical and LTSS is required to achieve the intended outcomes of an intervention or program targeted at PLWD; if integration is needed, select carefully the types of medical and LTSS to integrate and the mode of integration; (2) use measures that evaluate quality across LTSS settings in which PLWD receive care; (3) assess whether and how eligibility and payment policies pose barriers to PLWD from receiving services they need, and evaluate ways in which policies might be reformed to meet beneficiaries’ needs; and (4) conduct research examining the potential of value-based payment efforts to improve the quality and efficiency of care received by PLWD, including their potential impact on out-of-pocket expenses and caregiving burden for PLWD and their families.     

Quality of Life and Quality of Care for People With Dementia Receiving Long Term Institutional Care or Professional Home Care: The European RightTimePlaceCare Study

ObjectivesTo explore how quality of life (QoL) and quality of care (QoC) for people with dementia (PwD) vary across 8 European countries; to explore how QoL and QoC for PwD vary across living arrangements; and to assess the association between QoL and QoC.DesignCross-sectional survey.SettingInstitutional long term care and home care in 8 European countries (England, Estonia, Finland, France, Germany, the Netherlands, Spain, and Sweden).ParticipantsPwD receiving formal home care but at risk for admission to an institutional setting, and PwD who were recently admitted.MeasurementsQoL was assessed by the PwD and by their best informed proxies using the Quality of Life-Alzheimer's Disease scale (QoL-AD) (range 13–52). QoC was measured using quality of care indicators (eg, the presence of depressive symptoms, the presence of pressure ulcers).ResultsA total of 1123 PwD living at home (mean age 82.2, 63%women) and 791 PwD living in institutional care (mean age 84.1, 74% women) participated. QoL of PwD was most often rated highest in Sweden and England and lowest in Estonia and Spain. No differences in QoL were detected among the settings. For the QoC indicators, no consistent patterns were visible in such a way that certain countries or settings scored “higher” or “lower.” The presence of depressive symptoms was most consistently associated with lower QoL (P ≤ .001).ConclusionThere is great variation in QoL and QoC scores among European countries and settings. To gain insight into the underlying causes of these differences, more knowledge is needed about the effect of different national health care systems and dementia strategies on QoL and QoC indicators. Depressive symptoms were associated with QoL, and executing longitudinal studies investigating which factors are associated with change in QoL is highly recommended.     

Systematic Review of Factors Associated With Hearing Aid Use in People Living in the Community With Dementia and Age-Related Hearing Loss

ObjectivesTo investigate factors that influence hearing aid use according to the Theoretical Domains Framework (TDF). The TDF is a behavioral science framework that aids understanding of factors that influence behavior.DesignSystematic review.Setting and ParticipantsPeople living in the community with dementia and age-related hearing loss who have air conduction hearing aids.MethodsSystematic literature review following PRISMA guidelines. We searched for studies in 9 databases, including Ovid MEDLINE, Scopus, and OpenGrey. We undertook an interpretive data synthesis by mapping findings onto the TDF. We assessed confidence in the findings according to the GRADE-CERQual approach.ResultsTwelve studies (6 quantitative, 3 qualitative, and 3 mixed methods) were included in the review. The majority of these were rated low-moderate quality. We identified 27 component constructs (facilitators, barriers, or noncorrelates of hearing aid use) nested within the 14 domains of the TDF framework. Our GRADE-CERQual confidence rating was high for 5 findings. These suggest that hearing aid use for people living in the community with dementia and hearing loss is influenced by (1) degree of hearing aid handling proficiency, (2) positive experiential consequences, (3) degree of hearing aid comfort or fit, (4) person-environment interactions, and (5) social reinforcement.Conclusions and ImplicationsHearing aid interventions should adopt a multifaceted approach that optimizes the capabilities of people with dementia to handle and use hearing aids; addresses or capitalizes on their motivation; and ensures their primary support network is supportive and encouraging of hearing aid use. The findings also emphasize the need for further high-quality research that investigates optimal hearing aid use, influencing factors, and interventions that support hearing aid use.
