Impact of proactive rounding by a rapid response team on patient outcomes at an academic medical center

Abstract

The impact of rapid response teams (RRT) on patient outcomes remains uncertain. To examine the effect of proactive rounding by an RRT on outcomes of hospitalized adults discharged from intensive care. Retrospective, observational study. Academic medical center. All adult patients discharged alive from the intensive care unit (ICU) at the University of California San Francisco Medical Center between January 2006 and June 2009. Introduction of proactive rounding by an RRT. Outcomes included the ICU readmission rate, ICU average length of stay (LOS), and in-hospital mortality of patients discharged from the ICU. Data were obtained from administrative billing databases and analyzed using an interrupted time series (ITS) model. We analyzed 17 months of preintervention data and 25 months of postintervention data. Introduction of proactive rounding by the RRT did not change the ICU readmission rate (6.7% before vs 7.3% after; P = 0.24), the ICU LOS (5.1 days vs 4.9 days; P = 0.24), or the in-hospital mortality of patients discharged from the ICU (6.0% vs 5.5%; P = 0.24). ITS models testing the impact of proactive rounding on secular trends found no improvement in any of the 3 clinical outcomes relative to their preintervention trends. Proactive rounding by an RRT did not improve patient outcomes, raising further questions about RRT benefits.
