Objective: to identify risk factors associated with development of delirium in aged people hospitalized for clinical treatment. Method: an integrative literature review. The search was conducted in February 2022 by applying the search strategy in electronic portals and databases, such as Biblioteca Virtual em Saúde, PubMed/MEDLINE and Web of Science. Results: the search yielded 965 articles. After removing duplicates, 583 had their titles and abstracts read. After applying the eligibility criteria, 127 studies were submitted to full reading, with exclusion of 110 and analysis of 17, totaling a sample comprised by 6,170 patients The studies included were those conducted with patients ≥ 60 years of age, clinical treatment, assessment of risk factors for delirium; and the excluded studies were those that used non-validated instruments, case reports, theses, monographs, review articles or that did not answer the research question. The most frequently found risk factors were presence of cognitive deficit and dementia. Other factors also found were as follows: advanced age, presence of fever/infection, dehydration, functional deficit, use of psychotropic drugs before hospitalization, severity of underlying diseases, polypharmacy, visual impairment, pain at rest, presence of diabetes mellitus, frailty and hospitalization time in the emergency sector. Conclusions: the studies point to various risk factors associated with delirium and highlight the relevance of the care team recognizing this condition. Fast and effective actions to prevent delirium in aged people depends on its identification. The health team should be alert during the care provided to vulnerable populations so that the screening of sings, which are often fluctuating, is facilitated.
