UTI risk factors in older people living with dementia: A conceptual framework and a scoping review

Abstract

Background and Aims: UTIs greatly impact hospitalization rates for people living with dementia. This study aims to craft a framework through a scoping review, assessing UTI symptoms, risk factors, and non-pharmacological prevention strategies in older people living with dementia. Research Design and Methods: Our scoping review followed PRISMA-ScR guidelines, exploring databases (PubMed, CINAHL, Embase, Web of Science) for topics like geriatric care, urinary tract issues published from January 1977 to April 2023. Two reviewers assessed data, organizing it using the Social-Ecological Model to construct the UTI Prevention (UTIP) framework. Results: The literature review scrutinized 1394 articles, selecting 14 through rigorous evaluation. It detailed demographic characteristics, synthesized UTI symptoms, 14 risk factors, and seven outcomes for older people living with dementia. Moreover, it outlined ten preventive domains and proposed a comprehensive UTI Prevention (UTIP) framework spanning individual, relational, community, and societal levels. This framework aims to prevent UTIs among older people living with dementia, integrating risk factors and outcomes to bolster effective prevention strategies for this population. Discussion and Implications: The review introduced a UTIP framework, and non-pharmacological preventive measures tailored for elderly people living with dementia. However, some factors in the framework require further validation to strengthen their associations with outcomes. Preventive measures from studies had limitations like small sample sizes, bias risks, and inconsistent findings. Future research should prioritize robust randomized trials with strong statistical power, strict criteria, and consistent individual-level interventions to boost outcome reliability and validity. Such efforts will enhance the credibility of findings and contribute significantly to refining preventive strategies for this vulnerable population.
