BACKGROUNDDementia is regularly associated with behavioral and psychological symptoms of dementia (BPSD, also referred to as challenging behavior). Structured dementia-specific case conferences (DSCCs) enable nursing staff in nursing homes (NHs) to analyze and handle the BPSD of residents with dementia. The FallDem trial estimated the effectiveness of the structured DSCC intervention WELCOME-IdA (Wittener model of case conferences for people with dementia - the Innovative dementia-oriented Assessment tool) in NHs in Germany. No significant change in the overall prevalence of challenging behavior was found. A multipart process evaluation was conducted to explain this result. METHODSThis qualitative process evaluation of the response of individuals, perceived maintenance, effectiveness, and unintended consequences was part of the multipart process evaluation that followed the framework by Grant et al. (Trials 14: 15, 2013). It used the data from semi-structured telephone interviews and focus group interviews with nurses and managers as secondary data. Selected domains of the Consolidated Framework for Implementation Research (CFIR) were used as deductive categories for a directed content analysis. RESULTSThe interviewees in all NHs appraised WELCOME-IdA as generating positive change, although it proved important that some adjustments were made to the intervention and the organization. Thirteen CFIR constructs out of the domains intervention characteristics, inner setting, and process proved to be essential for understanding the different course that the implementation of WELCOME-IdA took in each of the four NHs. This is reflected in three types of WELCOME-IdA implementation: (1) priority on adjusting the intervention to fit the organization, (2) priority on adjusting the organization to fit the intervention, and (3) no setting of priorities in adjusting either the organization or the intervention. CONCLUSIONThe unsatisfying results of the FallDem effectiveness trial can in part be explained with regard to the interplay between the intervention and the implementation which was revealed in the processes that occurred in the organizations during the implementation of the WELCOME-IdA intervention. Future implementation of WELCOME-IdA should be tailored based on an analysis of the organization's readiness, resources, and capacities and should also define custom-made intervention and implementation outcomes to measure success. Furthermore, our results confirm that
