External Intensivists Versus In-House Intensivists: Analysis of Outcomes of Nighttime Coverage of ICUs by External On-Call and In-House On-Call Intensivists.

A 24/7 intensivist model may improve important outcomes such as mortality, length of stay, and number of ventilator days. In this retrospective, single-center study at Saint Luke's Hospital in Kansas City, Missouri, we examined patient outcomes before and after adopting a 24/7 model from 2014 to 2016. The addition of a nighttime intensivist did not lead to a statistically significant improvement in mortality (hospital and ICU) and LOS (hospital and ICU).
