Early intervention on the outcomes in critically ill cancer patients admitted to intensive care units

Purpose

To determine whether earlier intervention was associated with decreased mortality in critically ill cancer patients admitted to an intensive care unit (ICU).

Methods

A retrospective observational study was performed of 199 critically ill cancer patients admitted to the ICU from the general ward between January 2010 and December 2010. A logistic regression model was used to adjust for potential confounding factors in the association between time to intervention and in-hospital mortality.

Results

In-hospital mortality was 52?%, with a median Simplified Acute Physiology Score 3 (SAPS 3) of 80 [interquartile range (IQR) 67–93], and a median Sequential Organ Failure Assessment (SOFA) score of 8 (IQR 5–11). Median time from physiological derangement to intervention (time to intervention) prior to ICU admission was 1.5 (IQR 0.6–4.3)?h. Median time to intervention was significantly shorter in survivors than in non-survivors (0.9 vs. 3.0?h; p?p?2/FiO₂ ratio. Even after adjusting for potential confounding factors, time to intervention was still significantly associated with hospital mortality (adjusted odds ratio 1.445, 95?% confidence interval 1.217–1.717).

Conclusions

Early intervention before ICU admission was independently associated with decreased in-hospital mortality in critically ill cancer patients admitted to the ICU.
