Meta-analysis of psychosocial interventions for caregivers of people with dementia

OBJECTIVES: To review published reports of interventions for caregivers (CGs) of persons with dementia, excluding respite care, and provide recommendations to clinicians. DESIGN: Meta-analytical review. Electronic databases and key articles were searched for controlled trials, preferably randomized, published in English from 1985 to 2001 inclusive. Thirty studies were located and scored according to set criteria, and the interventions' research quality and clinical significance were judged. SETTING: Home or noninstitutional environment. PARTICIPANTS: Informal CGs-persons providing unpaid care at home or in a noninstitutional setting. MEASUREMENTS: The primary measures were psychological morbidity and burden. Other varied outcome measures such as CG coping skills and social support were combined with measures of psychological distress and burden to form a main outcome measure. RESULTS: The quality of research increased over the 17 years. Results from 30 studies (34 interventions) indicated, at most-current follow-up, significant benefits in caregiver psychological distress (random effect size (ES) = 0.31; 95% confidence interval (CI) = 0.13-0.50), caregiver knowledge (ES = 0.51; CI = 0.05-0.98), any main caregiver outcome measure (ES = 0.32; CI = 0.15-0.48), and patient mood (ES = 0.68; CI = 0.30-1.06), but not caregiver burden (ES = 0.09; CI = -0.09-0.26). There was considerable variability in outcome, partly because of differences in methodology and intervention technique. Elements of successful interventions could be identified. Success was more likely if, in addition to CGs, patients were involved. Four of seven studies indicated delayed nursing home admission. CONCLUSION: Some CG interventions can reduce CG psychological morbidity and help people with dementia stay at home longer. Programs that involve the patients and their families and are more intensive and modified to CGs' needs may be more successful. Future research should try to improve clinicians' abilities to prescribe interventions.     

Preparing for pragmatic trials in dementia care: Health equity considerations for nonpharmacological interventions

Inequities with regard to brain health, economic costs, and the evidence base for dementia care continue. Achieving health equity in dementia care requires rigorous efforts that ensure disproportionately affected populations participate fully in—and benefit from—clinical research. Embedding-proven interventions under real-world conditions and within existing healthcare systems have the potential to examine the effectiveness of an intervention, improve dementia care, and leverage the use of existing resources. Developing embedded pragmatic controlled trials (ePCT) research designs for nonpharmacological dementia care interventions involves a plethora of a priori assumptions and decisions. Although frameworks exist to determine whether interventions are “ready” for ePCT, there is no heuristic to assess health equity-readiness. We discuss health equity considerations, case examples, and research strategies across ePCT study domains of evidence, risk, and alignment. Future discussions regarding health equity considerations across other domains are needed.     

The effect of nonpharmacological interventions on pain and sleep quality after percutaneous nephrolithotomy: A protocol for systematic review and network meta-analysis

Background:Various nonpharmacological interventions have been applied to alleviate pain and improve sleep quality after percutaneous nephrolithotomy. However, evidence to compare their efficacy is scant. This study aims to evaluate the efficacy of different nonpharmacological interventions on alleviating pain and improving sleep quality in patients after percutaneous nephrolithotomy through a network meta-analysis.Methods:Randomized controlled trials reporting the efficacy of nonpharmacological interventions on alleviating pain and improving sleep quality in patients after percutaneous nephrolithotomy will be searched in online databases, including the Chinese Scientific Journal Database, China National Knowledge Infrastructure Database, Wanfang, China Biomedical Literature Database, Pubmed, Web of Science, Embase, and Cochrane Library. After quality assessment and date extraction, network meta-analysis will be performed using Stata 14.0 and R software.Results:The results of this meta-analysis will be submitted to a peer-reviewed journal for publication.Conclusions:This study will provide systematic and comprehensive evidence-based support for the effects of nonpharmacological interventions on alleviating pain and improving sleep quality after percutaneous nephrolithotomy.Ethics and dissemination:Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms.REGISTRATION NUMBER:DOI 10.17605/OSF.IO/B4DHW.     

Effectiveness of Montessori-based activities on agitation among Asian patients with dementia: A systematic review and meta-analysis

Objectives:Montessori based activity are supposed to be an effective nonpharmacological intervention in the treatment of agitation in western countries. However, most studies conducted to evaluate the effectiveness of Montessori based activities on agitation in Asian patients were small sample size, as well as inconsistent outcomes, which may limit the reliability of the conclusions. The present pooled analysis, hence, was conducted to evaluate the effectiveness of the activity on agitation related with dementia in Asian patients with dementia.Design:Prospective randomized clinical studies were included, of which available data was extracted. Outcomes of physical aggressive behaviors, physical nonaggressive behaviors, and verbal aggressive behaviors were pooled for the analysis by weighted mean differences.Data sources:Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), WanFang, and China Science and Technology Journal Database (VIP)Eligibility criteria:Prospective, randomized, controlled clinical studies, conducted to evaluate the effectiveness of the activity on agitation related with dementia in Asian patients with dementia.Data extraction and synthesis:Available data including baseline characteristics and interested outcomes from the included literature were extracted independently by 2 investigators. Measuring scales including CMAI and NOSIE were adopted for the efficacy comparison between Montessori based activity and standard activity. Weighted mean difference was used for the pooled analysis.Results:A total of 460 participants were included in the present meta-analysis. The pooled mean difference agitation for Montessori based activity was –3.86 (95% CI: –7.38 to –0.34, P = 0.03) comparing to standard activity. The pooled mean differences for physical aggressive behaviors, physical nonaggressive behaviors, and verbal aggressive behaviors in Montessori based activity group were –0.82 (95% CI: –1.10 to –0.55; P < 0.00001), –0.81 (95% CI: –1.68 to 0.55; P = 0.07), and 0.38 (95% CI: –0.92 to 1.68; P = 0.57).Conclusions:Montessori based activities may reduce the frequency of agitation, especially in physical aggressive behaviors comparing to standard activities in Asian patients with dementia. However, the effectiveness of Montessori based activities on reduction of subcategorized agitated behaviors including physical nonaggressive behaviors, and verbal aggressive behaviors may not be reliable as physical aggressive behaviors.     

Effectiveness of nonpharmacological interventions for the management of neuropsychiatric symptoms in patients with dementia: a systematic review

BACKGROUND: Recent reports documenting limited evidence supporting the use of pharmacological interventions for neuropsychiatric symptoms (NPS) and increased risk of death, the black box warnings against the use of atypical antipsychotic drugs in older adults, and Omnibus Budget Reconciliation Act regulations suggest the need to evaluate the usefulness of nonpharmacological interventions in the management of NPS of dementia. METHODS: To determine the evidence base of nonpharmacological interventions for the management of NPS in patients with dementia, we reviewed MEDLINE, PsycINFO, the Cochrane library, and relevant bibliographies published from January 1966 to December 2005, using the American Psychological Association Guidelines. RESULTS: Three randomized controlled trials (RCTs) and 6 single-case designs (SCDs; N of 1 trials) met inclusion criteria. Under unmet needs interventions, 1 SCD found a moderate reduction in problem behaviors. Under behavioral interventions, based on observational data, all 4 SCDs reported a relative reduction of 50% to 100% in neuropsychiatric symptoms. Under caregiving interventions, there were 3 RCTs. At the 6-month follow-up, 1 RCT found a reduction in 4 neuropsychiatric symptom subscales: ideation disturbance score (0.3 vs 0.5; range, 0-8; P = .005); irritability score (18.8 vs 23.0; range, 8-38; P = .008); verbal agitation, as measured by mean frequency of 20-minute outbursts (0.5 vs 0.8; P = .005); and physical aggression score (11.4 vs 12.9; range, 6-42; P<.001). Another RCT found a significant improvement in frequency (2.3 vs 3.1; range, 0-4; P<.001) and severity (2.2 vs 2.8; range, 0-4; P<.001) of target behaviors associated with the intervention arm. The third RCT found no effect. Under bright light therapy, 1 SCD found short-term improvements on the Agitated Behavior Rating Scale (9.7 vs 19.9; P<.001). CONCLUSIONS: The cumulative research to date on the impact of nonpharmacologic interventions for NPS among patients with dementia indicates that interventions that address behavioral issues and unmet needs and that include caregivers or bright light therapy may be efficacious. More high-quality research is necessary to confirm these findings.     

Effects of magnesium valproate adjuvant therapy on patients with dementia: A systematic review and meta-analysis

Background:Current research has found contradictory results on the treatment of magnesium valproate (VPM) in patients with dementia (PwD).Objectives:Here, we conducted a meta-analysis to evaluate the efficacy and safety of VPM in the adjuvant treatment of PwD.Purpose:Current research has found contradictory results on the treatment of VPM in PwD. Here, we conducted a meta-analysis to evaluate the efficacy and safety of VPM in the adjuvant treatment of PwD.Methods:MEDLINE via PubMed, Cochrane Library, EBSCO, Embase, China National Knowledge (CNKI), and Wan Fang databases were researched to gather relevant data on magnesium valproate assistant therapy for patients with dementia (PwD) by using medical subject headings and term words.Results:After the final screening, 22 RCT studies (a total of 1899 participants) were included in this meta-analysis, which compared VPM adjuvant treatment with antidementia or psychotropic drug monotherapy. Significant differences were found in the scores on mini-mental state examination (P = .028), Alzheimer disease assessment scale cognitive subscale (P < .05), Bech-Rafaelsen Mania Rating Scale (P < .05), behavioral pathology in Alzheimer disease rating scale (P = .001), activities of daily living (P < .05), and Pittsburgh Sleep Quality Index (P < .05). Besides, the levels of inflammatory factors including IL-1β, IL-6, and TNF-α were significantly lower than those in the monotherapy group (P < .05). While there was no increase in the incidence of adverse events (P = .383), VPM as an assistant therapy is generally well tolerated in PwD.Conclusion:By meta-analysis, evidence was found to support VPM additional used for the treatment of cognitive function, psychiatric symptoms, or disease improvement in PwD. VPM may be a potential drug to aid in the treatment of dementia patients. However, there was lack of enough evidence to classification of dementia severity in our inclusion study. More research is still needed, including clinical trials evaluating VPM as a complementary therapy.     

Magnesium valproate adjuvant therapy on patients with dementia: A protocol for systematic review and meta-analysis

Background:With the aging population, the prevalence and incidence of dementia disease will continue to rise, and the associated economic burden is increasing as well. However, the available anti-dementia therapeutic arsenal is limited. Meanwhile, magnesium valproate (VPM) as an adjuvant therapy had a general positive effect on the cognitive function and psychiatric symptoms of patient with dementia (PwD). At present, there is lack of meta-analysis focusing on cognitive improvement and disease-modifying about VPM-assisted therapy in the present peer-reviewed literature. Thus, we aimed to likely analyze the efficacy and safety of VPM adjuvant therapy of PwD.Methods:We will research MEDLINE via PubMed, Cochrane Library, EBSCO, Embase, China National Knowledge (CNKI) and Wan fang databases to gather relevant data on VPM assistant therapy on the PwD. Meta-analysis will be performed using Stata16.0 software.Results:We aim to evaluate the efficacy and safety of VPM in the adjuvant treatment of PwD.Conclusion:VPM maybe plays an active role in the treatment of dementia patients and this research will provide reliable evidence for clinicians in therapy of PwD.INPLASY registration number:INPLASY2021110038 (DOI: 10.37766/inplasy2021.11.0038).     

Effectiveness of interventions on feeding difficulties among people with dementia: A systematic review and meta-analysis

Objectives

This systematic review and meta-analysis aimed to examine non-pharmacological interventions for helping people with dementia who experience feeding difficulties in order to improve their nutritional status.

Methods

The articles were searched using PsycINFO, Medline, PubMed, CINAHL and Cochrane. Two independent investigators critically appraised eligible studies. The PRISMA guidelines and checklist were used. The possibility of risk of bias was assessed using a tool to assess the quality of randomised control trials (RCT) and non-RCT studies. A narrative synthesis was conducted as a method of synthesis. The Cochrane Review Manager (RevMan 5.4) was used for meta-analysis.

Results

The systematic review and meta-analysis included seven publications. Six interventions were identified and categorised as: eating ability training for people with dementia, staff training and feeding assistance and support. The meta-analysis found evidence of the effect of eating ability training on feeding difficulty, quantified by the Edinburgh Feeding Evaluation in Dementia scale (EdFED) with a weighted mean difference of −1.36 (95% confidence interval: −1.84 to −0.89, p < 0.001) and on self-feeding time. A spaced retrieval intervention showed a positive effect on EdFED. The systematic review discovered that while feeding assistance had a positive effect on feeding difficulty, staff training had no effect. According to the meta-analysis, these interventions had no effect on improving the nutritional status of people with dementia.

Conclusions

None of the included RCTs met the Cochrane risk-of-bias criteria for randomised trials. This review found that direct training for people with dementia and indirect feeding support from care staff resulted in fewer mealtime difficulties. More RCT studies are needed to determine the efficacy of such interventions.     

Effectiveness of peer-led interventions to increase HIV testing among men who have sex with men: a systematic review and meta-analysis

HIV testing constitutes a key step along the continuum of HIV care. Men who have sex with men (MSM) have low HIV testing rates and delayed diagnosis, especially in low-resource settings. Peer-led interventions offer a strategy to increase testing rates in this population. This systematic review and meta-analysis summarizes evidence on the effectiveness of peer-led interventions to increase the uptake of HIV testing among MSM. Using a systematic review protocol that was developed a priori, we searched PubMed, PsycINFO and CINAHL for articles reporting original results of randomized or non-randomized controlled trials (RCTs), quasi-experimental interventions, and pre- and post-intervention studies. Studies were eligible if they targeted MSM and utilized peers to increase HIV testing. We included studies published in or after 1996 to focus on HIV testing during the era of combination antiretroviral therapy. Seven studies encompassing a total of 6205 participants met eligibility criteria, including two quasi-experimental studies, four non-randomized pre- and-post intervention studies, and one cluster randomized trial. Four studies were from high-income countries, two were from Asia and only one from sub-Saharan Africa. We assigned four studies a “moderate” methodological rigor rating and three a “strong” rating. Meta-analysis of the seven studies found HIV testing rates were statistically significantly higher in the peer-led intervention groups versus control groups (pooled OR 2.00, 95% CI 1.74–2.31). Among randomized trials, HIV testing rates were significantly higher in the peer-led intervention versus control groups (pooled OR: 2.48, 95% CI 1.99–3.08). Among the non-randomized pre- and post-intervention studies, the overall pooled OR for intervention versus control groups was 1.71 (95% CI 1.42–2.06), with substantial heterogeneity among studies (I^2?=?70%, p?相似文献   

Nonpharmacological interventions for cancer-related fatigue in lung cancer patients: A protocol for an evidence map of overview of a network meta-analysis of existing trials

Background:Lung cancer is one of the most common cancers, the symptoms and treatment of which can cause negative emotions like anxiety, depression, and cancer-related fatigue (CRF). Nonpharmacological interventions, serving as alternative therapies, can greatly alleviate CRF in lung cancer patients. Previous meta-analyses have reported nonpharmacological interventions of CRF in lung cancer patients, but the results may be conflicting, and the reporting and methodological qualities remain unknown. Moreover, there is limited evidence to identify efficient and safe non-pharmacological interventions of CRF in lung cancer patients. This study aims to assess the therapeutic efficacy of nonpharmacological interventions of CRF in lung cancer patients through a network meta-analysis.Methods:Relevant literatures reporting non-pharmacological interventions of CRF in lung cancer patients published before June 2021 will be searched in online databases, including Wanfang, VP Information Chinese Journal Service Platform, China National Knowledge Infrastructure, Chinese BioMedicine Literature Database, PubMed, Embase, Cochrane, and Web of science. Two reviewers will be independently responsible for study selection, quality appraisal, and data extraction. Data analysis will be performed using the STATA14.0 and GEMTC 0.14.3 software.Results:This meta-analysis will provide additional and stronger evidences for nonpharmacological interventions of CRF in lung cancer patients. Our findings will be conductive to make therapeutic decisions by clinicians.Conclusion:This study will provide a reliable evidence-based basis for non-pharmacological interventions of CRF in lung cancer patients.Ethics and dissemination:Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms. This review would be disseminated in a peer-reviewed journal or conference presentations.OSF REGISTRATION NUMBER:DOI 10.17605/OSF.IO/QRY42.

Patient and caregiver characteristics associated with depression in caregivers of patients with dementia

OBJECTIVE: Many patients with dementia who live at home would require nursing home care if they did not have the assistance of family caregivers. However, caregiving sometimes has adverse health consequences for caregivers, including very high rates of depression. The goal of this study was to determine the patient and caregiver characteristics associated with depression among caregivers of patients with dementia. DESIGN: Cross-sectional study. PARTICIPANTS AND SETTING: Five thousand six hundred and twenty-seven patients with moderate to advanced dementia and their primary caregivers upon enrollment in the Medicare Alzheimer's Disease Demonstration (MADDE) at 8 locations in the United States. MEASUREMENTS: Caregiver depression was defined as 6 or more symptoms on the 15-item Geriatric Depression Scale. Patient characteristics measured included ethnicity and other demographic characteristics, income, activities of daily living (ADL) function, Mini-Mental Status Exam (MMSE) score, and behavioral problems. Caregiver characteristics measured included demographic characteristics, relationship to the patient, hours spent caregiving, and ADL and Instrumental Activities of Daily Living (IADL) function. We used chi2 and t tests to measure the bivariate relationships between patient and caregiver predictors and caregiver depression. We used logistic regression to determine the independent predictors of caregiver depression. RESULTS: Thirty-two percent of caregivers reported 6 or more symptoms of depression and were classified as depressed. Independent patient predictors of caregiver depression included younger age (odds ratio [OR], 1.91; 95% confidence interval [CI], 1.33 to 2.76 in patients less than 65 years compared to patients over 85 years), white (OR, 1.53; 95% CI, 1.18 to 1.99) and Hispanic ethnicity (OR, 2.50; 95% CI, 1.69 to 3.70) compared to black ethnicity, education (OR, 1.16; 95% CI, 1.01 to 1.33 for those with less than a high school education), ADL dependence (OR, 1.55; 95% CI, 1.26 to 1.90 for patients dependent in 2 or more ADL compared to patients dependent in no ADL), and behavioral disturbance, particularly angry or aggressive behavior (OR, 1.47; 95% CI, 1.27 to 1.69 for patients with angry or aggressive behavior). Independent caregiver predictors of depression included low income (OR, 1.45; 95% CI, 1.18 to 1.77 for less than 10,000 dollars/per year, compared to >20,000 dollars per year), the relationship to the patient (OR, 2.73; 95% CI, 1.31 to 5.72 for wife, compared to son of male patient), hours spent caregiving (OR, 1.89; 95% CI, 1.51 to 2.38 for 40 to 79 hours/week compared to less than 40 hours/week), and functional dependence (OR, 2.53; 95% CI, 2.13 to 3.01 for ADL dependent compared to IADL independent). CONCLUSION: Caregiver depression is a complex process, influenced by ethnicity as well as diverse patient and caregiver characteristics. Efforts to identify and treat caregiver depression will need to be multidisciplinary and focus on multiple risk factors simultaneously.     

Training caregivers to change the sleep hygiene practices of patients with dementia: the NITE-AD project

OBJECTIVES: To examine the feasibility of training caregivers to implement sleep hygiene recommendations in dementia patients. DESIGN: A randomized, controlled trial. SETTING: Community. PARTICIPANTS: Twenty-two community-dwelling patients with Alzheimer's disease (AD) and their family caregivers. INTERVENTIONS: All participants received written materials describing age- and dementia-related changes in sleep and standard principles of good sleep hygiene. Caregivers in active treatment (n=10) also received specific recommendations about setting up and implementing a sleep hygiene program for the dementia patient. Control subjects (n=12) received general dementia education and caregiver support. MEASUREMENTS: Success implementing sleep hygiene recommendations was measured using daily log reports to calculate the percentage of days that caregivers reported that patients met individualized sleep scheduling, daytime-napping, and walking goals. RESULTS: Caregivers in active treatment were more successful in setting goals related to sleep scheduling and increasing daytime activity than control caregivers who received written materials only. Among patients who were candidates for sleep hygiene changes, active treatment subjects were also significantly (P<.01) more likely than controls to maintain a consistent bedtime (83% vs 38% of days attempted) and a consistent rising time (96% vs 59%), to nap less during the day (70% vs 28%), and to walk daily (86% vs 7%). CONCLUSION: This study provides evidence that sleep hygiene interventions are feasible with community-dwelling AD patients. Caregivers were able to help patients change sleep scheduling, napping, and walking routines, but clinicians who recommend sleep hygiene changes for their dementia patients should be aware that many caregivers need active assistance setting up and implementing a sleep hygiene program. Simply providing caregivers with education is often insufficient.
