This phenomenon has been associated with higher mortality rates in patients that are not admitted despite their need and in patients that are admitted but are waiting for a bed. The purpose of this study is to evaluate if a delay in ICU admission affects mortality for critically ill patients. Methods A prospective cohort of adult patients admitted to the ICU of our institution between January and December 2005 were analyzed. Patients for whom a bed was available were immediately admitted when no bed was available patients waited for ICU admission. ICU admission was classified as either delayed or immediate. Confounding variables examined were age sex originating hospital ward ICU diagnosis co-morbidity Acute Physiology and Chronic Health Evaluation APACHE II score therapeutic intervention and Sequential Organ Failure Assessment SOFA score. All patients were followed until hospital discharge. Results A total of 401 patients were evaluated 125 31.2 patients were immediately admitted and 276 68.8 patients had delayed admission. There was a significant increase in ICU mortality rates with a delay in ICU admission P 0.002 . The fraction of mortality risk attributable to ICU delay was 30 95 confidence interval CI 11.2 to 44.8 . Each hour of waiting was independently associated with a 1.5 increased risk of ICU death hazard ratio HR 1.015 95 CI 1.006 to 1.023 P 0.001 . Conclusions There is a significant association between time to admission and survival rates. Early admission to the
