Main Article Content
Abstract
INTRODUCTION: Delirium is a cognitive disorder typical of critical illness, it is linked to increased mortality, longer hospital stay, higher ICU requirements, greater functional impairment and the need for rehabilitation and chronic care units. OBJECTIVE: To identify and evaluate the evidence of the last 5 years regarding the definition and diagnosis of delirium in adults hospitalized in the ICU through a review of systematic reviews and meta-analyses. MATERIALS AND METHODS: An Umbrella review guided by JBI guidelines. Data were obtained from Science direct, Web of science, Scielo, CINAHL, PubMed, Virtual Health Library (VHL) and Cochrane Library. The last search was carried out on March 28, 2022. RESULTS: Fourteen reviews met the inclusion criteria, the definition of delirium from the perspective of patients and families, prevalence of risk factors and accuracy of the different scales such as CAM-ICU, ICDSC, PREDELIRIC and E-PREDILIRC have good predictive values. CONCLUSIONS: Hypoactive delirium has a higher prevalence and incidence in ICUs. It is necessary that the health personnel adopt certain attitudes with the patient with delirium.
