The effect of Delirium on short term outcomes in patients admitted to Intensive Care Unit

Delirium is one of the most commonly occurring disorders in the intensive care unit. Various studies have been done in this regard. In this study, we investigate the frequency and effect of Delirium on the short-term outcome of patients admitted to Imam Hospital in Urmia province. This cross-sectional study was conducted to determine the frequency and effect of delirium on short-term outcomes (duration of mechanical ventilation, duration of hospitalization in ICU, duration of hospitalization, mortality) in patients admitted to the General Intensive Care Unit (GICU) of Imam Hospital in Urmia province during 2015. Demographic characteristics, underlying illness, duration of mechanical ventilation, length of hospitalization in intensive care unit, duration of hospitalization, mortality and delirium of patients entered the check Listed. Independent T test and Fisher exact test was used to analyze data. This study was included 322 patients. There was no significant difference between patients in term of age, sex and mortality (P> 0.05). Although, there were significant difference between two groups of patients in term of underlying disease, duration of mechanical ventilation and the length of hospitalization and duration of hospitalization in intensive care unit(P<0.5). Moreover, 18.94% of the patients suffered from delirium and the rest did not have delirium. The present study showed that delirium is a relatively common disorder in ICU. Moreover, its prevalence is different in compared to other studies. Furthermore, delirium can affect duration of mechanical ventilation, duration of hospitalization in intensive care unit and length of hospitalization.
