In the Intensive Care Unit (ICU) the application of the Richmond Agitation Sedation Scale (RASS) and the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), are not systematically implemented in the clinical practice. At Pasteur Hospital´s ICU, they were not applied until 2013. In 2014-2015 the first prospective study on delirium in the ICU showed a low use and degree of compliance of the scales (RASS: 0.17 [DE 0.07], CAMICU: 0.20 [DE 0.11]). In 2016, educational workshops were implemented in the use of CAM-ICU to screen delirium. Evaluate the improvement in the application of RASS and CAM-ICU. Describe the incidence of delirium and related variables post educational interventions. Descriptive, prospective study of patients admitted to the Pasteur Hospital ICU between March 1 and May 31, 2017 Inclusion criteria: age ≥ 18, stay ≥ 24 hours. Training: dissemination of RASS and CAM-ICU, workshop and bedside mode. Use of the tool: ratio of patients evaluated by RASS and CAM-ICU. Delirium was diagnosed with CAM-ICU positive, evaluating its incidence and related variables. Training increased the use of the tools, being even lower than recommended. The incidence of delirium was 48%. We must continue educating.
