Purpose: An intensivist is a key factor in the mortality of patients admitted to the intensive care unit (ICU). The aim of this study was to evaluate the effect of an intensivist on clinical outcomes of patients admitted to a surgical ICU.
Methods: During the study period, the surgical ICU was converted from an open ICU to an intensivist-directed ICU managed by an intensivist who was board certified in both general surgery and critical care medicine. We compared consecutive patients admitted to the surgical ICU before and after implementing the intensivist-directed care. The primary outcome was ICU mortality, and secondary outcomes were hospital mortality, 90-day mortality, length of hospital stay, ICU-free days, ventilator-free days, and ICU readmission rate.
Results: A total of 441 patients were included in this study: 188 before implementation of the intensivist and 253 after implementation. Clinical characteristics were not different between the two groups. ICU mortality decreased from 11.7% to 6.3% (P = 0.047) after implementation, and 90-day mortality also decreased significantly (P = 0.008). The adjusted hazard ratio of the intensivist for ICU mortality was 0.43 (95% confidence interval, 0.22-0.87; P = 0.020). ICU-free days (P = 0.013) and the hospital length of stay (P = 0.032) were significantly improved after implementing the intensivist-directed care. Before implementation period, 16.0% of patients were readmitted, compared with only 9.9% after implementation (P = 0.05).
Conclusion: Implementing intensivist-directed care in the surgical ICU was associated with significant improvements in ICU mortality and significant clinical outcomes.
