[People in need of care at home: the relevance of incontinence and falls]. / Inkontinenz und Stürze erschweren die Pflege zu Hause.

The geriatric syndromes of incontinence and falls not only affect patients living in care homes, but increasingly also patients in their own homes. This particularly affects patients with cognitive impairments. A high nursing home admission age in an ageing population means that these geriatric syndromes are part of everyday care in the home. It is recommended to educate patients in particular about ways to prevent falls and incontinence - promoting mobility and exercise play a key role here.

Reduction and prevention of agitation in persons with neurocognitive disorders: an international psychogeriatric association consensus algorithm.

OBJECTIVES: To develop an agitation reduction and prevention algorithm is intended to guide implementation of the definition of agitation developed by the International Psychogeriatric Association (IPA). DESIGN: Review of literature on treatment guidelines and recommended algorithms; algorithm development through reiterative integration of research information and expert opinion. SETTING: IPA Agitation Workgroup. PARTICIPANTS: IPA panel of international experts on agitation. INTERVENTION: Integration of available information into a comprehensive algorithm. MEASUREMENTS: None. RESULTS: The IPA Agitation Work Group recommends the Investigate, Plan, and Act (IPA) approach to agitation reduction and prevention. A thorough investigation of the behavior is followed by planning and acting with an emphasis on shared decision-making; the success of the plan is evaluated and adjusted as needed. The process is repeated until agitation is reduced to an acceptable level and prevention of recurrence is optimized. Psychosocial interventions are part of every plan and are continued throughout the process. Pharmacologic interventions are organized into panels of choices for nocturnal/circadian agitation; mild-moderate agitation or agitation with prominent mood features; moderate-severe agitation; and severe agitation with threatened harm to the patient or others. Therapeutic alternatives are presented for each panel. The occurrence of agitation in a variety of venues-home, nursing home, emergency department, hospice-and adjustments to the therapeutic approach are presented. CONCLUSIONS: The IPA definition of agitation is operationalized into an agitation management algorithm that emphasizes the integration of psychosocial and pharmacologic interventions, reiterative assessment of response to treatment, adjustment of therapeutic approaches to reflect the clinical situation, and shared decision-making.

Agitation in cognitive disorders: Progress in the International Psychogeriatric Association consensus clinical and research definition.

BACKGROUND: The International Psychogeriatric Association (IPA) published a provisional consensus definition of agitation in cognitive disorders in 2015. As proposed by the original work group, we summarize the use and validation of criteria in order to remove "provisional" from the definition. METHODS: This report summarizes information from the academic literature, research resources, clinical guidelines, expert surveys, and patient and family advocates on the experience of use of the IPA definition. The information was reviewed by a working group of topic experts to create a finalized definition. RESULTS: We present a final definition which closely resembles the provisional definition with modifications to address special circumstances. We also summarize the development of tools for diagnosis and assessment of agitation and propose strategies for dissemination and integration into precision diagnosis and agitation interventions. CONCLUSION: The IPA definition of agitation captures a common and important entity that is recognized by many stakeholders. Dissemination of the definition will permit broader detection and can advance research and best practices for care of patients with agitation.

Typology of Dementia-Specific Care Units: A Nationwide Survey Study in Germany.

Background and Objectives: Dementia-specific care units vary in their organizational characteristics and are difficult to compare in empirical studies. Based on a representative sample of care units in German nursing homes, we present a typology of organizational characteristics focusing on dementia-specific care structures. We also examine the relationships between organizational types and the provision of nonpharmacological interventions for people with dementia. Research Design and Methods: Data were collected in a Germany-wide survey of a stratified randomized sample of 134 care units using a standardized questionnaire administered during telephone interviews with nursing home administrators or their representatives. The typology was developed based on a factor analysis of mixed data and a hierarchical cluster analysis. Results: We identified 4 types of care units: Dementia Care Units (DCUs; n = 40), Dementia Special Care Units (DSCUs; n = 17), Usual Separated Care Units (n = 58), and Usual Incorporated Care Units (n = 19). All care unit types clearly differed in their organizational characteristics. The specialization of DSCUs was agreed upon with cost bearers and included admission criteria, higher costs, and better staff conditions. Dementia Care Units without specialization did not have these characteristics. Three of seven nonpharmacological interventions were associated with the DSCUs and two with DCUs, but not with the other care unit types. Discussion and Implications: Researchers can use the typology to define and describe care units in empirical studies and improve the understanding and comparability of the context. A clear definition of care units also improves international comparisons.

How and why educational interventions work to increase knowledge of delirium among healthcare professionals in nursing homes: a protocol for a realist review.

BACKGROUND: Delirium is a neuropathological condition that impairs cognitive performance, attention and consciousness and can be potentially life-threatening. Nursing home residents are particularly vulnerable to developing delirium, but research thus far tends to focus on the acute hospital setting. Healthcare professionals (HCPs) working in nursing homes seem to be little aware of delirium. To improve healthcare for affected or at-risk individuals, increasing knowledge among HCPs is highly relevant. Using the realist review method helps to understand how and why an educational intervention for HCPs on delirium in nursing homes works. METHODS AND ANALYSIS: In accordance with the Realist And Meta-narrative Evidence Syntheses: Evolving Standards publication standards for realist syntheses, the review process will include the following five steps: (1) search strategy and literature review; (2) study selection and assessment; (3) data extraction; (4) data synthesis and (5) development of an initial programme theory. The literature search will be conducted in the databases Medline (PubMed), CINAHL (Ebsco), Scopus, Web of Science, GeroLit and Carelit. Additional focuses are on snowballing techniques, hand research and grey literature. Studies of any design will be included to develop the initial programme theory. The literature will be selected by two researchers independently. In addition, the experiences of HCPs from nursing homes will be reflected in group discussions. To this end, Context-Mechanism-Outcome configurations (CMOcs) will be established to develop an initial programme theory. ETHICS AND DISSEMINATION: The results will be disseminated within the scientific community. For this purpose, presentations at scientific conferences as well as publications in peer-reviewed journals are scheduled. In the next step, the CMOcs could serve for the development of a complex educational intervention to increase the knowledge of HCPs on delirium in nursing homes. REGISTRATION DETAILS: This protocol has been registered at Open Science Framework (https://doi.org/10.17605/OSF.IO/HTFU4).

Measurement instruments to evaluate diaper dermatitis in children: Systematic review of measurement properties.

AIM: The aim of this study was to summarize and evaluate the empirical evidence on the measurement properties of diaper dermatitis (DD) measurement instruments in children. DESIGN: Systematic review. METHODS: MEDLINE, CINAHL and EMBASE were systematically searched until 14 June 2021. Citation searching was conducted in Scopus. The risk of bias, the reported measurement properties and the quality of evidence were evaluated using the COSMIN framework. The reporting follows the PRISMA 2020 statement. RESULTS: We identified 1200 records in the databases and 108 records during citation searching and included four studies describing three measurement instruments for DD in children and their measurement properties. We considered the content validity inconsistent for all three instruments. The study authors reported internal consistency, reliability and construct validity for one instrument. We rated the quality of evidence from very low to moderate.

Age-specific incidence of need for long-term care for men and women in Germany 2015: Cross-sectional study comprising 82 million people.

Background: With the growing number of older people, the number of people in need of long-term care is increasing, too. Official statistics only report on the age-specific prevalence of long-term care. Therefore, there is no data on the age- and sex-specific incidence of the need for care at the population level for Germany available. Methods: Analytical relationships between age-specific prevalence, incidence rate, remission rate, all-cause mortality, and mortality rate ratio are used to estimate the age-specific incidence of long-term care among men and women in 2015. The data is based on the official prevalence data from the nursing care statistics for the years 2011 to 2019 and official mortality rates from the Federal Statistical Office. For Germany, there is no data on the mortality rate ratio of people with and without a need for care, which is why we use two extreme scenarios that were obtained in a systematic literature search to estimate the incidence. Results: The age-specific incidence is about 1 per 1000 person-years (PY) in men and women at the age of 50 and increases exponentially up to the age of 90. Up to about the age of 60, men have a higher incidence rate than women. Thereafter, women have a higher incidence. At the age of 90, women and men have an incidence rate of 145 to 200 and 94 to 153 per 1000 PY, respectively, depending on the scenario. Conclusion: We estimated the age-specific incidence of the need for long-term care for women and men in Germany for the first time. We observed a strong increase, leading to a huge number of people in need of long-term care in higher age groups. It is to be expected that this will result in an increased economic burden and a further increased need for nursing and medical staff.

Theory-based evaluation and programme theories in nursing: A discussion on the occasion of the updated Medical Research Council (MRC) Framework.

Developing and evaluating health interventions for the benefit of patients is notoriously difficult. This also applies to the discipline of nursing, owing to the complexity of nursing interventions. Following significant revision, the updated guidance of the Medical Research Council (MRC) adopts a pluralistic view to intervention development and evaluation, including a theory-based perspective. This perspective promotes the use of program theory, aiming to understand how and under what circumstances interventions lead to change. In this discussion paper, we reflect the recommended use of program theory in the context of evaluation studies addressing complex nursing interventions. First, we review the literature by investigating the question whether and how evaluation studies targeting complex interventions used theory and to what extent program theories may contribute to enhance the theoretical foundations of intervention studies in nursing. Second, we illustrate the nature of theory-based evaluation and program theories. Third, we argue how this may impact theory building in nursing in general. We finish by discussing which resources, skills and competencies are necessary to fulfill the demanding task of undertaking theory-based evaluations. We caution against an oversimplified interpretation of the updated MRC guidance regarding the theory-based perspective, e.g. by using simple linear logic models, rather than articulating program theories. Instead, we encourage researchers to embrace the corresponding methodology, i.e. theory-based evaluation. With the prevailing perspective of knowledge production in crisis, we might be on the verge of a paradigm shift in health intervention research. Viewed through this lens, the updated MRC guidance could lead to a renewed understanding of what constitutes useful knowledge in nursing. This may facilitate knowledge production and, thereby, contribute to improve nursing practice for the benefit of the patient. TWEETABLE ABSTRACT: The latest iteration of the MRC Framework for developing and evaluating complex healthcare interventions could lead to a renewed understanding of what constitutes useful knowledge for nursing.

[The contribution of advanced practice nurses in Swiss family practices: Multiple case study design]. / Der Beitrag von Advanced Practice Nurses in Schweizer Hausarztpraxen.

The contribution of advanced practice nurses in Swiss family practices: Multiple case study design Abstract. Background: The increase in chronic diseases, multimorbidity and shortage of health professionals make it essential to adapt primary health care. New models of care are needed which are oriented towards patient needs and thus ensure comprehensive care for chronically ill people. In this context, there is great potential for the use of advanced practice nurses in Swiss family practices. Aims: In this study we investigated the contribution of advanced practice nurses in the interprofessional context in two family practices. Methods: We conducted a multiple case study design. We investigated two advanced practice nurses, located in family practices in rural and in mountainous regions. We used qualitative and quantitative methods. As an intermediate step, within-case analyses were performed and we summarized data inductively to create case vignettes. Results: The cases showed that advanced practice nurses contribute to self-management, prevention and health promotion in complex, stable and unstable patients. These areas have not been covered adequately by other health professionals in family practices. They strengthened interface management through hybrid employment and flexible, addressee-appropriate communication. Conclusions: Similarities and differences between family practices with and without new professional roles should be elicited to specifically identify gaps in care for the chronically ill.

Adapting the Australian Environmental Assessment Tool-High Care (EAT-HC): Experiences and Practical Implications From Germany, Japan, and Singapore.

BACKGROUND: Assessing the built environment in nursing homes is part of several established instruments. Measurements are primarily published in English, so there is a need for cross-cultural adaptation to be able to use them in other countries. This procedure should be carried out alongside translation guidelines to ensure successful adaptation not only for assessments that capture complex constructs, such as the built environment, but also for assessments to be applied in healthcare in general. OBJECTIVE: This article presents different approaches to adopt the Australian Environmental Assessment Tool-High Care (EAT-HC) based on the World Health Organization (WHO) guidelines for instrument translation. The comparison of these processes should provide implications for further adaptations of the instrument. METHODS: The adaptation processes carried out in Germany, Japan, and Singapore were compared using thematic analysis. Steps taken to achieve linguistic validation and to adopt the tool were analyzed qualitatively in the context of overarching needs for adjustment. RESULTS: Every perspective adapted the WHO guidelines for their respective purposes of applying the EAT-HC. The order of steps varied, but elements to validate the results with the instruments' creators and to ensure validity were included in all three countries. For items that might be challenging, we detected possible reasons that might help future adaptors manage this process more efficiently. CONCLUSION: The EAT-HC benefits from adaptation alongside the WHO guidelines in terms of enhancing the quality of translation and feasibility of application. Individual supplementary adaptation steps allow the identification of culture-specific needs for application in other countries.

Core elements and potential of nurse-led care models in residential long-term care: A scoping review.

AIMS AND OBJECTIVE: To identify and summarise core elements, resident-, staff- and process-related outcomes and challenges of nurse-led care models in residential long-term care. BACKGROUND: Due to demographic trends, the complexity of residential long-term care has increased. To address this complexity, the implementation of nurse-led care models has been recommended. DESIGN: Scoping review. METHODS: A systematic search was conducted of English and German articles in CINAHL via EBSCO, MEDLINE via PubMed, Cochrane Library and Scopus. Forward and backward citation tracking via reference lists and Google Scholar supplemented the search. The final update was made on 19 January 2021. To draw conclusions about the potential of nurse-led care models, evaluation studies of the described models for residents in nursing homes were included. Full texts were independently screened and assessed for methodological quality. Data were extracted and summarised in tables and synthesised for analysis. The core elements of the models were described using the Sustainable intEgrated chronic care modeLs for multimorbidity: delivery, FInancing and performancE (SELFIE) framework. The review followed the PRISMA-ScR guideline. RESULTS: We included 13 studies of 12 nurse-led care models. The different models comprised many of the core elements suggested in the SELFIE framework, particularly in the components service delivery, workforce, and leadership and governance. The studies reported a broad range of resident-, staff- and process-related outcomes and challenges considered relevant to the success of the models. CONCLUSIONS: Studies evaluating nurse-led care models in nursing homes are limited and of moderate quality. This review demonstrates that nurse-led care models include many elements for care coordination and could improve resident-, staff- and process-related outcomes. RELEVANCE TO CLINICAL PRACTICE: This review highlights that nurse-led care models share common core elements despite their heterogeneity. It also shows that highly qualified nurses in nurse-led care models can advance nursing practice in nursing homes.

Competencies of nurse practitioners in family practices: A scoping review.

AIMS AND OBJECTIVE: To explore the existing literature related to nurse practitioner (NP) competencies in family practices and to examine the evidence and develop a list of competencies. BACKGROUND: The integration of NPs into the healthcare system is at different stages of progress around the world. Therefore, an overview and clarification of competencies are important to ensure successful implementation of new roles in existing healthcare systems. However, detailed knowledge is lacking about the competencies of NPs in adult care in family practices. DESIGN AND METHODS: We conducted a scoping review in accordance with the JBI methodology for scoping reviews and the PRISMA-ScR guidelines. We considered studies published in English, German or French from 1965 to the present. Databases searched included MEDLINE, CINAHL, Web of Science and PsycINFO. Sources of grey literature that were searched included ProQuest Dissertations and Theses, OpenGrey and websites of national NP organisations. Two reviewers retrieved full-text studies and extracted data independently. We described the competencies using Hamric's model of advanced practice nursing. RESULTS: We included 23 publications. Competencies in direct clinical practice were described most often particularly pertaining to nursing or medical tasks. Indirect care activities were frequently mentioned. Less information was found regarding competencies in leadership, ethical decision-making and evidence-based practice. We found elementary and extended competencies required to perform the role in family practices. Depending on the country, the role was either emerging or already well-established. CONCLUSIONS AND RELEVANCE TO CLINICAL PRACTICE: This review provides insight into current knowledge about competencies of NP in family practices. The identified competencies can be used to develop job descriptions or to conceptualise professional development programmes in countries where such roles are just recently emerging. A list of competencies will promote a common understanding of the NP role and to help clarify interprofessional collaboration in clinical practice.

Measuring person-centred care in german nursing homes - exploring the construct validity of the Dementia Policy Questionnaire: a cross-sectional study of a secondary data set.

BACKGROUND: To ensure the sustainable implementation of dementia-specific person-centred care (PCC) in nursing homes, internal policies are crucial. The preliminary German Dementia Policy Questionnaire, which features 19 dichotomous items, assesses the existence of and evaluates these policies. This article reports the results of an exploration of the construct validity of the preliminary Dementia Policy Questionnaire. METHODS: This study is a cross-sectional study that references a secondary data set drawn from a national survey study of a randomized, stratified sample of 134 nursing homes in Germany. To explore the construct validity of the preliminary Dementia Policy Questionnaire, we conducted an adjusted multiple correspondence analysis of the pretested 19-item assessment. We included data assessed using the preliminary Dementia Policy Questionnaire from 134 care units associated with 134 nursing homes; these data were collected via telephone interviews with nursing home administrators or their representatives. RESULTS: Two items assessing visitor regulations and regulations regarding the inclusion of residents in staff selection were less frequent and were therefore excluded from the adjusted multiple correspondence analysis. In total, nine items were assigned to two dimensions. The items assigned to the first dimension assess existing regulations for PCC as well as existing regulations regarding the involvement of the resident, relatives and the multiprofessional team in the collection of information concerning preferences, case conferences or decision making. The items assigned to the second dimension assess existing regulations regarding the systematic assessment of resident preferences and their requirements. CONCLUSION: The study produces exploratory evidence concerning the preliminary Dementia Policy Questionnaire. Since the dimensions of the items included in this questionnaire cannot be conceptualized clearly, the instrument in its current state requires further development.

Feasibility, Interrater Reliability and Internal Consistency of the German Environmental Audit Tool (G-EAT).

Dementia-specific environmental design has the potential to positively influence capabilities for daily living and quality of life in people with dementia living in nursing homes. To date, no reliable instrument exists for systematically assessing the adequacy of these built environments in Germany. This study aimed to test the adapted version of the Environmental Audit Tool-High Care (EAT-HC)-the German Environmental Audit Tool (G-EAT)-with regard to its feasibility, interrater reliability and internal consistency. The G-EAT was applied as a paper-pencil version in the German setting; intraclass correlation coefficients at the subscale level ranged from 0.662 (III) to 0.869 (IV), and 42% of the items showed at least substantial agreement (Cohen's kappa ≥ 0.60). The results indicate the need to develop supplementary material in a manual that illustrates the meaning of the items and practical implications regarding dementia-specific environmental design. Furthermore, the intersectionality of built and physical environments must be considered when interpreting G-EAT results in future research and applications to residential long-term care practice.

German Translation, Linguistic Validation, and Cultural Adaptation of the Environmental Audit Tool-High Care.

BACKGROUND: In dementia-specific care, the design of the environment is regarded as an influential element in the support and maintenance of skills and can improve the quality of life of residents. To date, there is no valid instrument in the German-speaking countries with which the quality of the physical environment in residential long-term care facilities can be systematically assessed. OBJECTIVE: To report the translation, linguistic validation, cultural adaptation, and content validity evaluation of the Australian Environmental Audit Tool-High Care in preparation for use in German nursing homes. METHOD: The procedure was guided by an adapted multistep process of the World Health Organization (1998) and included focus groups involving potential users of the new tool such as scientific experts and healthcare professionals (n = 40). Content validity indices were calculated following a two-step expert survey. RESULTS: The final draft versions of the German Environmental Audit Tool (G-EAT) included 74 and 77 items, for non-secured units and secure units, respectively, divided into 10 key design principles according to the Australian original. The evaluation of content validity showed that cultural differences existed in several items. CONCLUSIONS: The G-EAT provides the means for conducting a valid assessment of the environmental quality of people with dementia in German nursing homes. However, its usability in healthcare research must be preceded by testing its interrater reliability.

Context, mechanisms and outcomes of dementia special care units: An initial programme theory based on realist methodology.

BACKGROUND: Dementia special care units represent a widely implemented care model in nursing homes. Their benefits must be thoroughly evaluated given the risk of exclusion and stigma. The aim of this study is to present an initial programme theory that follows the principles of realist methodology. The theory development was guided by the question of the mechanisms at play in the context of dementia special care units to produce or influence outcomes of interest in people with dementia. METHODS: The initial programme theory is based on qualitative interviews with dementia special care stakeholders in Germany and a realist review of complex interventions in dementia special care units. The interviews were analysed using content analysis techniques. For the realist review, a systematic literature search was conducted in four scientific databases; studies were appraised for quality and relevance. All data were analysed independently by two researchers. A realist informed logic model was developed, and context-mechanism-outcome (CMO) configurations were described. RESULTS: We reviewed 16 empirical studies and interviewed 16 stakeholders. In the interviews, contextual factors at the system, organisation and individual levels that influence the provision of care in dementia special care units were discussed. The interviewees described the following four interventions typical of dementia special care units: adaptation to the environment, family and public involvement, provision of activities and behaviour management. With exception of family and public involvement, these interventions were the focus of the reviewed studies. The outcomes of interest of stakeholders include responsive behaviour and quality of life, which were also investigated in the empirical studies. By combining data from interviews and a realist review, we framed three CMO configurations relevant to environment, activity, and behaviour management. DISCUSSION: As important contextual factors of dementia special care units, we discuss the transparency of policies to regulate dementia care, segregation and admission policies, purposeful recruitment and education of staff and a good fit between residents and their environment.

Dementia specific care structures in nursing homes-Study protocol of a telephone-based survey study in a nationwide random sample.

AIM: To describe a study protocol for a survey study in German nursing homes that (1) plans to enhance a typology of care units (2) and investigates the association between different care unit types and the provision of dementia-specific interventions based on a stratified randomized sample. BACKGROUND: Many nursing homes in Germany provide Dementia Special Care Units. Existing definitions often do no justice to the complexity of their context. In this study, we define context as structural and organizational variables. It is necessary to define an empirical based set of indicators to characterize care units with respect to dementia care. DESIGN: Observational survey study with a cross-sectional design. METHODS: We will use a stratified random nationwide sample of 160 German nursing homes. Stratification variables are federal state and the existence of a Dementia Special Care Unit. The sampling frame from which the participating nursing homes are selected is a list with the total population of German nursing homes (n = 11.658). Data will be gathered on the level of the nursing homes and one of their care units via computer-assisted telephone interviews with a standardized questionnaire. The distribution of the assessed variables (contextual characteristics) will be described in absolute and relative frequencies for the whole sample in the first step in order to describe dementia-specific care structures. In the second step, factor analysis of mixed data (FAMD) with hierarchical clustering (HC) will be applied to analyze relationships between variables. The study was ethically approved in October 2018. DISCUSSION: The typology can be used in future studies to define the context of care units in nursing homes. This may improve the interpretation of findings from future studies that investigated interventions in nursing homes. IMPACT: The typology will visualize and describe the complexity of contextual characteristics of several care units.

[Preferences for everyday living written in the nursing record - An explorative document analysis in various nursing settings]. / Präferenzen des alltäglichen Lebens in der Pflegedokumentation.

Preferences for everyday living written in the nursing record - An explorative document analysis in various nursing settings Abstract. Background: In Germany, there was previously no instrument for the systematic recording of preferences for the everyday living of older and people in need of care. Subsequently, in a pilot study, an instrument was translated in a culturally sensitive way (PELI-D), piloted and tested psychometrically. In terms of documentation quality, it is important that the preferences recorded by nursing staff are written down in the nursing record using PELI-D, plausibly based on the nursing process. AIM: To find out which preferences, assessed by the nursing staff in the pilot study with the PELI-D, were written down in the nursing record. METHODS: An exploratory document analysis was carried out. Included were 13 nursing records and five discussion participants from five institutions in three nursing settings. The data were evaluated descriptively and by a structuring content analysis. RESULTS: A total of 2% of the preferences, which were assessed with the PELI-D, were found in the nursing records and may be due to the use of PELI-D. Preferences mainly from the categories "interventions" and "biography" were found in the nursing record. CONCLUSIONS: 98% of the preferences assessed with the PELI-D were not written down. This can probably be attributed to the fact that the PELI-D was an "innovation" for the nursing staff. Therefore, the execution of an implementation study seems to be reasonable to improve the plausibility of the captured PELI-D data in the nursing documentation. In the context of this, it is also recommended to analyze how the PELI-D influences nursing processes and contents of the nursing record.

Relationship between the severity of agitation and quality of life in residents with dementia living in German nursing homes - a secondary data analysis.

BACKGROUND: Severe agitation and its relation to single dimensions of quality of life are not well understood. The aim of this study was to gain more knowledge about severe agitation and to examine the relationships between the severity of agitation and single dimensions of quality of life among residents with dementia living in German nursing homes. METHODS: This exploratory secondary analysis included data from 1947 residents of 66 German nursing homes from the DemenzMonitor study. The construct of agitation was defined as a composite score of the items agitation/aggression, irritability/lability and disinhibition from the Neuropsychiatric Inventory Questionnaire (NPI-Q); the resident was classified as severely agitated if at least one of these symptoms was rated as 'severe'. The single dimensions of quality of life were measured with the short version of the QUALIDEM instrument. To avoid selection bias, two controls with mild or no agitation were selected for each resident with severe agitation using propensity score matching. Mixed linear regression models were then generated to determine the differences in the dimensions of quality of life for the severity of agitation and the defining items. RESULTS: For four out of five dimensions of quality of life of the short version of QUALIDEM, residents with severe agitation had significantly lower values than residents without severe agitation. Converted to scale size, the greatest difference between both groups was found in the dimension social isolation with 23.0% (-2.07 (95% CI: -2.57, -1.57)). Further differences were found in the dimensions restless tense behaviour with 16.9% (-1.52 (95% CI: -2.04, -1.00)), positive affect with 14.0% (-1.68 (95% CI: -2.28, -1.09)) and social relations with 12.4% (-1.12 (95% CI: -1.54, -0.71)). CONCLUSIONS: Severe agitation is a relevant phenomenon among nursing home residents with dementia and is associated with lower values of quality of life in the dimensions social isolation, restless tense behaviour, positive affect and social relations from the QUALIDEM instrument. Therefore, more attention should be paid to severe agitation in nursing practice and research. Moreover, care strategies used to reduce severe agitation should be considered in terms of their impact on the dimensions of quality of life.
