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., (© 2022. The Author(s).)

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., (© 2021 The Authors.

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. [ABSTRACT FROM AUTHOR]
