Impact of implementing a critical care team in an open general ICU


High-intensity ICU physician staffing is associated with reduced ICU mortality [1]. We formed a critical care team (CCT) that consisted of five teaching staff interested in critical care management. The CCT had been activated by each member of the team if needed and had provided rapid medical services including consultation. We evaluated the impact of implementing the CCT on open general ICU patient outcomes.


We performed a prospective observational study in an open general ICU between March 2009 and February 2010 according to CCT. We compared demographic data, ICU mortality rates, length of ICU stay, APACHE II scores, Sequential Organ Failure Assessment (SOFA) scores, patients who received mechanical ventilation, and success rates of weaning in CCT with those in non-CCT.


We analyzed 857 patients' data (161 cases in CCT vs. 696 cases in non-CCT), excluding readmission cases. Patients who received CCT management were more severe than those who received non-CCT management significantly (APACHE II 21.4 vs. 17.7; SOFA 5.8 vs. 4.9). Although there were more patients on applied mechanical ventilation (46% vs. 23.6%) in CCT than those in non-CCT and a higher success rate of weaning (60.8% vs. 43.9%) in CCT than those in non-CCT, there was no significant difference of unadjusted ICU mortality rates in both groups (14.3% in CCT vs. 12.2% in non-CCT). Using a multivariate logistic regression model, the ICU mortality rate was associated with non-CCT, APACHE II scores, SOFA scores, and applied mechanical ventilation (Table 1).

Although the CCT was not a full-time coverage team in the open general ICU, the CCT model was associated with reduced ICU mortality, especially in patients who received mechanical ventilation.
