The main goal of this article is, applying the UTAUT 2 (the unified theory of acceptance and use of technology), to verify the factors determining the implementation of business intelligence tools in business processes, especially decision-making, and their subsequent optimal use in business practice. The researched scheme was modified according to the specifics of business intelligence tools and was supplemented by user behaviour in decision-making. The verification was performed using a questionnaire survey based on UTAUT 2 theory and 152 respondents were included in the analysis. According to the results, the most important variable of influence on both the behavioural intention and the users' behaviour itself in decision-making was the factor of habit. And surprisingly, some previously recognised links were not confirmed, especially the factors influencing the intention of behaviour (effort expectancy, social influence, facilitating conditions). So, there is room after almost 10 years and experience gained during the Covid-19 pandemic to modify the latest version of a model.</p>","PeriodicalId":9689,"journal":{"name":"Central European Journal of Operations Research","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9672574/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40702331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This makes it important to encourage and empower patients with chronic diseases to take care of themselves. An associated goal of such efforts is to significantly reduce the burden on healthcare systems and positively impact patients' health outcomes and quality of life. The paper presents a multi-criteria decision model for assessing the health and self-care of patients with chronic diseases in the home environment. The model is based on the DEX methodology and was tested on ten cases. The model assists with the timely recognition of relevant symptoms and signs in decision-making about health and self-care. It can be used to promote patients taking on an active role with respect to caring for their health and well-being. The model could be integrated into self-care processes. It might also serve as a basis for an interprofessional approach to supporting older patients with chronic diseases living as fully and independently as possible in the environment in which they feel most comfortable.</p>","PeriodicalId":9689,"journal":{"name":"Central European Journal of Operations Research","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9614758/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40675364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
