Intensive care unit (ICU)-related mortality for lung cancer is ranked highest among the solid tumors and little information exists on the role of intensivists on clinical outcomes. This study aimed to elucidate the intensivist's contribution toward clinical outcomes.


Data of advanced lung cancer patients, including stage IIIB or IV non-small cell lung cancer and extensive-stage small cell lung cancer, admitted to the ICU from 2005 to 2016 were analyzed. Multivariate logistic regression was performed to determine variables associated with ICU and in-hospital mortality. Autoregressive integrated moving average (ARIMA) for time-series was used to assess the intensivist's impact.


Of 264 patients, 85 (32.2%) were admitted to the ICU before and 179 (67.8%) after organized intensive care introduction in 2011. Before and after 2011, the changes observed were as follows: ICU mortality rate, 43.5% to 40.2%, respectively (p = 0.610); hospital mortality rate, 82.4% to 65. 9% (p = 0.006). The duration of ICU and hospital stay decreased after 2011 (14.5±16.5 vs. 8.3 ± 8.6, p < 0.001; 36.6 ± 37.2 vs. 22.0 ± 19.6, p < 0.001). On multivariate analysis, admission after 2011 was independently associated with decreased hospital mortality (Odds ratio 0.42, 95% confidence interval 0.21-0.77, p = 0.006). In ARIMA models, intensivist involvement was associated with significantly reduced hospital mortality. (Estimate -17.95, standard error 5.31, p = 0.001).


In patients with advanced lung cancer, organized intensive care could contribute to improved clinical outcomes.
