Abstract
Prevalence of neuropsychiatric symptoms of people with dementia in long-term care units: A secondary analysis Abstract: Background: In a progress of dementia, most people develop neuropsychiatric symptoms. However, there is little knowledge about the prevalence of these symptoms and their specific characteristics in long-term care. Aims: A differentiated investigation of the prevalence and characteristics of neuropsychiatric symptoms in people with dementia in a long-term care setting. Methods: The prevalence of neuropsychiatric symptoms of people with dementia in a long-term care setting was examined using a secondary analysis of cross-sectional data from the research projects LebenQD I and II and FallDem. The data were collected using the neuropsychiatric inventory - nursing home version. The analysis included data from 699 people with dementia from a total of 21 long-term care facilities in North Rhine-Westphalia. Results: The symptoms agitation/aggression (36%), depression/dysphoria (33%), apathy/indifference (33%), irritability/lability (30%) and aberrant motor behaviour show the highest prevalence. The symptoms hallucinations (9%) and euphoria/elation (6%) have the lowest prevalence. Conclusions: The high prevalence of specific neuropsychiatric symptoms and their characteristics in people with dementia illustrates the need for care-related or psychosocial interventions to counteract the reasons for the occurrence of the symptoms.

Abstract
BACKGROUND AND OBJECTIVES Person-centered care is the gold standard of care for people living with dementia, yet few systematic reviews have detailed how it is delivered in practice. This mixed-methods review aimed to examine the delivery of person-centered care, and its effectiveness, for people living with dementia in residential aged care. RESEARCH DESIGN AND METHODS A systematic review and meta-analysis. Eligible studies were identified across 4 databases. Quantitative and qualitative studies containing data on person-centered care delivered to people with dementia living in residential aged care were included. Meta-analysis using a random-effects model was conducted where more than 3 studies measured the same outcome. A narrative meta-synthesis approach was undertaken to categorize verbatim participant quotes into representative themes. Risk of bias was undertaken using quality appraisal tools from the Joanna Briggs Institute. RESULTS 41 studies were identified for inclusion. There were 34 person-centered care initiatives delivered, targeting 14 person-centered care outcomes. 3 outcomes could be pooled. Meta-analyses demonstrated no reduction in agitation (standardized mean difference -0.27, 95% confidence interval [CI], -0.58, 0.03), improvement in quality of life (standardized mean difference -0.63, 95% CI: -1.95, 0.70), or reduced neuropsychiatric symptoms (mean difference -1.06, 95% CI: -2.16, 0.05). Narrative meta-synthesis revealed barriers (e.g., time constraints) and enablers (e.g., staff collaboration) to providing person-centered care from a staff perspective. DISCUSSION AND IMPLICATIONS The effectiveness of person-centered care initiatives delivered to people with dementia in residential aged care is conflicting. Further high-quality research over an extended time is required to identify how person-centered care can be best implemented to improve resident outcomes.

Abstract
Background The COVID-19 pandemic has underscored the daily challenges nursing home (NH) staff face caring for the residents living with Alzheimer's Disease and Related Dementias (ADRD). Non-pharmacological approaches are prioritized over off-label medication to manage the behavioral and psychological symptoms of ADRD. Yet, it is not clear how to best equip NH staff and families with the knowledge and strategies needed to provide non-pharmacological approaches to these residents. Methods This clustered randomized trial will compare team- and problem-based approaches to non-pharmacological ADRD care. The team-based approach includes core training for all NH staff using a common language and strategies to support continuity and sustainability. The problem-based approach capitalizes on the expertise of the professional healthcare providers to target issues that arise. A convergent mixed methods design will be used to examine (a) comparative effectiveness of the two approaches on long-term NH resident outcomes and (b) whether either approach is protective against the negative consequences of COVID-19. The primary outcome is the percentage of ADRD residents with off-label antipsychotic medication use, which will be evaluated with an intent-to-treat approach. Staff and family caregiver perspectives will be explored using a multiple case study approach. Conclusion This trial will be the first-ever evaluation of team- and problem-based approaches to ADRD care across multiple NHs and geographic regions. Results can provide health system leaders and policymakers with evidence on how to optimize ADRD training for staff in an effort to enhance ADRD care delivery.

Abstract
BACKGROUND The Dementia Care Mapping (DCM) method is an internationally recognized complex intervention in dementia research and care for implementing person-centered care. The Leben-QD II trial aimed to evaluate the effectiveness of DCM with regard to caregivers. METHODS The nine participating nursing home units were allocated to three groups: (1) DCM method experienced ≥ 1 year, (2) DCM newly introduced during this trial, and (3) regular rating of residents' quality of life (control group). Linear mixed models were fit to cluster-aggregated data after 0, 6, and 18 months, adjusting for repeated measurements and confounders. The primary outcome was the Approaches to Dementia Questionnaire (ADQ) score; the secondary outcomes were the Copenhagen Psychosocial Questionnaire (COPSOQ) and the Copenhagen Burnout Inventory (CBI). RESULTS The analysis included 201 caregivers with 290 completed questionnaires (all three data collection time points). The ADQ showed a significant time and time*intervention effect. At baseline, the estimated least-square means for the ADQ were 71.98 (group A), 72.46 (group B), and 71.15 (group C). The non-linear follow-up of group A indicated an estimated-least square means of 69.71 (T 1) and 68.97 (T 2); for group B, 72.80 (T 1) and 72.29 (T 2); and for group C, 66.43 (T 1) and 70.62 (T 2). CONCLUSIONS The DCM method showed a tendency toward negatively affecting the primary and secondary outcomes; this finding could be explained by the substantial deviation in adherence to the intervention protocol.

Abstract
Dementia Care Mapping is an internationally applied method for enhancing person-centred care for people with dementia in nursing homes. Recent studies indicate that leadership is crucial for the successful implementation of Dementia Care Mapping; however, research on this topic is rare. This case study aimed to explore the influence of leadership on Dementia Care Mapping implementation in four nursing homes. Twenty-eight interviews with project coordinators, head nurses and staff nurses were analysed using qualitative content analysis. Nursing homes that failed to implement Dementia Care Mapping were characterised by a lack of leadership. The leaders of successful nursing homes promoted person-centred care and were actively involved in implementation. While overall leadership performance was positive in one of the successful nursing homes, conflicts related to leadership style occurred in the other successful nursing homes. Thus, it is important that leaders promote person-centred care in general and Dementia Care Mapping in particular. Furthermore, different types of leadership can promote successful implementation. Trial registration of the primary study: Current Controlled Trials ISRCTN43916381.

Abstract
Background There are various definitions and diagnostic criteria for dementia, leading to discrepancies in case ascertainment in both clinical practice and research. We reviewed the different definitions, approaches and measurements used to operationalize dementia in health care studies in German nursing homes with the aim of discussing the implications of different approaches. Methods We conducted a systematic search of the MEDLINE and CINAHL databases to identify pre-2016 studies conducted in German nursing homes that focused on residents with dementia or cognitive impairment. In- or exclusion of studies were consented by all authors; data extraction was independently carried out by 2 authors (RP, SJ). The studies’ sampling methods were compared with respect to their inclusion criteria, assessment tools and methods used to identify the study population. Results We summarized case ascertainment methods from 64 studies. Study participants were identified based on a diagnosis that was evaluated during the study, or a recorded medical dementia diagnosis, or a recorded medical diagnosis either with additional cognitive screenings or using screening tests exclusively. The descriptions of the diagnostics that were applied to assess a diagnosis of dementia were not fully transparent in most of the studies with respect to either a clear reference definition of dementia or applied diagnostic criteria. If reported, various neuropsychological tests were used, mostly without a clear rationale for their selection. Conclusion Pragmatic considerations often determine the sampling strategy; they also may explain the variances we detected in the different studies. Variations in sampling methods impede the comparability of study results. There is a need to consent case ascertainment strategies in dementia studies in health service research in nursing homes. These strategies should consider resource constraints and ethical issues that are related to the vulnerable population of nursing home residents. Additionally, reporting about dementia studies in nursing homes need to be improved. If a diagnosis cannot be evaluated based on either ICD or DSM criteria, the study population may not be reported as having dementia. If a diagnosis is evaluated based on ICD or DSM criteria within the study, there is a need for more transparency of the diagnostic process.

Abstract
BACKGROUND Person-centered care (PCC) is a widely recognized concept in dementia research and care. Dementia Care Mapping (DCM) is a method for implementing PCC. Prior studies have yielded heterogeneous results regarding the effectiveness of DCM for people with dementia (PwD). We aimed to investigate the effectiveness of DCM with regard to quality of life (QoL) and challenging behavior in PwD in nursing homes (NHs). METHODS Leben-QD II is an 18-month, three-armed, pragmatic quasi-experimental trial. The sample of PwD was divided into three groups with three living units per group: (A) DCM applied since 2009, (B) DCM newly introduced during the study, and (C) a control intervention based on a regular and standardized QoL rating. The primary outcome was QoL measured with the Quality of Life-Alzheimer's Disease (QoL-AD) proxy, and the secondary outcomes were QoL (measured with QUALIDEM) and challenging behavior (measured with the Neuropsychiatric Inventory Nursing Home version, NPI-NH). RESULTS There were no significant differences either between the DCM intervention groups and the control group or between the two DCM intervention groups regarding changes in the primary or secondary outcomes. At baseline, the estimated least square means of the QoL-AD proxy for groups A, B, and C were 32.54 (confidence interval, hereafter CI: 29.36-35.72), 33.62 (CI: 30.55-36.68), and 30.50 (CI: 27.47-33.52), respectively. The DCM groups A (31.32; CI: 28.15-34.48) and B (27.60; CI: 24.51-30.69) exhibited a reduction in QoL values, whereas group C exhibited an increase (32.54; CI: 29.44-35.64) after T2. CONCLUSIONS DCM exhibited no statistically significant effect in terms of QoL and challenging behavior of PwD in NHs. To increase the likelihood of a positive effect for PwD, it is necessary to ensure successful implementation of the intervention.

Abstract
Background Challenging behaviors exhibited by individuals with dementia might result from an unmet need that they cannot communicate directly due to cognitive restrictions. A dementia-specific case conference represents a promising means of analyzing and exploring these unmet needs. The ongoing FallDem study is a stepped-wedged, cluster-randomized trial evaluating the effects of two different types of dementia-specific case conferences on the challenging behaviors of nursing home residents. This study protocol describes the process evaluation that is conducted, along with the FallDem study. The goal of the process evaluation is to explain potential discrepancies between expected and observed outcomes, and to provide insights into implementation processes and recruitment strategies, as well as the contexts and contextual factors that promote or inhibit the implementation of dementia-specific case conferences. Methods/Design The process evaluation will use a mixed-method design comprising longitudinal elements, in which quantitative and qualitative data will be gathered. Qualitative data will be analyzed using content analysis, documentary analysis and a documentary method. Quantitative data (standardized questionnaires) will be analyzed using descriptive statistics. Both types of data will complement one another and provide a more comprehensive picture of the different objects under investigation. Discussion The process evaluation will allow for a comprehensive understanding of the changing processes and mechanisms underlying the ‘black box’ of the complex intervention of the FallDem study. These findings will provide practical knowledge regarding issues related to the implementation of dementia-specific case conferences in nursing homes.

Abstract
Background Case conferences for people with dementia and challenging behaviors (e.g., apathy) are recommended as useful tools that enable staff in nursing homes to understand the behavior of people with this type of disease. Understanding peoples’ behaviors is the basis for the initiation of targeted interventions to improve the quality of care for people with dementia. Furthermore, case conferences demonstrate positive effects on burnout, dementia-specific burden, and vocational action competence of the staff. The two likely approaches for conducting case conferences include the following: A) using a structured assessment instrument, which guides the staff in understanding the residents’ behaviors and B) using a narrative approach in which the staff must identify the reasons for the residents’ behaviors in an unstructured manner. Case conferences are a complex intervention, and evaluating their multiple effects is challenging. The aim of this study protocol was to describe a likely solution for evaluating this type of complex intervention using a special cluster randomized trial. Methods In this stepped-wedged cluster randomized trial, the two interventions will be sequentially implemented every three months in a group of 12 nursing homes (clusters) with a minimum of 360 residents over 19 months (7 months of intervention for each cluster and follow-up). The primary outcome is the reduction of challenging behavior (measured with the neuropsychiatric inventory-nursing home version [NPI-NH]). Secondary outcomes are residents’ quality of life, prescription of psychotropic medications, staff burnout, dementia-related stress, and vocational action competence. The effectiveness of the study will be accompanied by a process evaluation. The primary data will be analyzed using a Bayesian mixed effect model; the secondary data will be analyzed using descriptive statistics and mixed effects models. Discussion The implementation and effect measurement of complex interventions such as case conferences within a cluster randomized trial are challenging (e.g., complex and intensive training, delayed treatment effect). In this study protocol, the methodological advantages and disadvantages of using the stepped wedge design to answer the research questions are discussed.

Measuring the quality of life in mild to very severe dementia: testing the inter-rater and intra-rater reliability of the German version of the QUALIDEM. Int Psychogeriatr 2014; 26:825-36.

Abstract
BACKGROUND Quality of life (Qol) is an increasingly used outcome measure in dementia research. The QUALIDEM is a dementia-specific and proxy-rated Qol instrument. We aimed to determine the inter-rater and intra-rater reliability in residents with dementia in German nursing homes. METHODS The QUALIDEM consists of nine subscales that were applied to a sample of 108 people with mild to severe dementia and six consecutive subscales that were applied to a sample of 53 people with very severe dementia. The proxy raters were 49 registered nurses and nursing assistants. Inter-rater and intra-rater reliability scores were calculated on the subscale and item level. RESULTS None of the QUALIDEM subscales showed strong inter-rater reliability based on the single-measure Intra-Class Correlation Coefficient (ICC) for absolute agreement ≥ 0.70. Based on the average-measure ICC for four raters, eight subscales for people with mild to severe dementia (care relationship, positive affect, negative affect, restless tense behavior, social relations, social isolation, feeling at home and having something to do) and five subscales for very severe dementia (care relationship, negative affect, restless tense behavior, social relations and social isolation) yielded a strong inter-rater agreement (ICC: 0.72-0.86). All of the QUALIDEM subscales, regardless of dementia severity, showed strong intra-rater agreement. The ICC values ranged between 0.70 and 0.79 for people with mild to severe dementia and between 0.75 and 0.87 for people with very severe dementia. CONCLUSIONS This study demonstrated insufficient inter-rater reliability and sufficient intra-rater reliability for all subscales of both versions of the German QUALIDEM. The degree of inter-rater reliability can be improved by collaborative Qol rating by more than one nurse. The development of a measurement manual with accurate item definitions and a standardized education program for proxy raters is recommended.

Abstract
Background: QUALIDEM is a standardized dementia-specific quality of life (Qol) measurement, which was developed and validated in the Netherlands. A German version has been available since 2008. This study protocol describes the design and methodology for the quality of life of people with dementia (Qol-Dem) project. Objective: This project aims to evaluate the reliability and validity of the German version of the QUALIDEM. Method: Due to the lack of both a universal definition of Qol and of standards to verify the validity of Qol measurements, this study is divided into three phases. The aim of the first theoretical phase is the development of a dementia-specific Qol model as a result of a meta-synthesis of qualitative studies. The second empirical phase consists of the three following steps: (a) an investigation of the scalability and internal consistency of the measure, (b) an evaluation of the interrater and intrarater reliability, and (c) an extensive evaluation of the validity of the QUALIDEM. The resulting Qol model (phase 1) will be used for the selection of appropriate comparators for validity testing. In the third phase, the QUALIDEM will be adapted, if necessary, based on the knowledge generated in the first two phases. Conclusion: The findings of the Qol-Dem project should deliver an accurate assessment of the psychometric properties of the German version of the QUALIDEM. The results will contribute to the further development of the instrument. Furthermore, the results will contribute to the theoretical development of the concept of Qol among people with dementia.
