- others, 2012), in order to restore preventive measurements to reduce its incidence, gravity and duration. The delirium have high frequency and with an impact bio-psico-economic in the patient and its environment , the prevention is the most effective and economic measure of tackling the delirium in its initial phase and nursing contributes to a great extent in this work . It is as well as in a titled previous study : validity of the model of prediction of the delirium in intensive care unit of Bucaramanga, realized by Torres and Páez in 2014 in the Comuneros universitarian Hospital of Bucaramanga brought up to the date an incidence of the delirium of 20.5%, with a mortality of 47.5% of the patients who do delirium during its stay in ICU , proving the efficacy od the model PREDELIRIC to predict the delirium in the first 24 hours of stay in ICU , in patients with high values its like say a PREDELIRIC result >50% Taking this study as a precedent there appears the target to determine the efficacy of the prevention program of delirium in the population of critical patients in Bucaramanga, (the Comuneros universitarian Hospital of Bucaramanga) across a randomized controlled clinical essay , in order to predict early in these patients the possibility of delirium development and to facilitate the application of preventive measurements not pharmacological in patients with high risk . these preventive measurements would be done across individualized interventions and they would be focused after the improved orientation , cognitive stimulation , early mobilization to listen to music with the intention of reduce the delirium incidence, of improving the cognition of the patients and avoiding its deterioration during the staying in the ICU , condition that can remain after its departure ( Inouye & others, 1999). Also, the results of this investigation will appear in a scientific article and scientific congresses in the área of health . Also, they will be announced to the universitarian community and the involved institution. Key words : Delirium, intensive care, prevention , nursing interventions. Like an important antecedent in Santander the group of research of the nursing program Everest execute a study to validate the prediction model PREDELIRIC to a spanish version , this study expose the need to identify and implement interventions of nursing to prevent the delirium in critical patients of Bucaramanga Our priority now is to apply the model of prediction PREDELIRIC validated in a spanish version to the population of critical patients to predict early in these patients the possibility of development of delirium , facilitating the specific application of not pharmacological preventive measurements in patient who is in high risk. These preventive measurements would be done across an individualized intervention and they would be focused to: to improve the orientation, cognitive stimulation , early mobilization, listen to music, in patients of high risk, Inouye & others (1999) All this , focused to improve the cognition of the patients and to avoid the cognitive deterioration presented during the stay in the ICU and that can remain after the departure of the patient in the ICU, Inouye
