Evaluation of the effectiveness of an automated sepsis predictive tool on patient outcomes.

Abstract

To evaluate the effectiveness of a multidisciplinary, hospital-wide program as part of an electronic sepsis alert tool. We used data from 15 hospitals about adult patients with severe sepsis or septic shock. Nine intervention hospitals implemented an Epic sepsis prediction tool, education, and standardized order sets (six control hospitals did not). A difference-in-difference approach evaluated their effectiveness: 1) pre-implementation period (January 1, 2016-November 15, 2018) and 2) implementation period (November 16, 2018-June 30, 2019). Outcomes included mortality, receipt of the SEP-1 bundle of care, broad spectrum antibiotic use, ICU stay, and length of stay of 6926 patients. The difference of 6.7 percentage points between the intervention and control groups in SEP-1 bundle completion was not statistically significant (p = 0.105). The increase over time for antibiotic administration ≤1 h of time zero was not larger for hospitals in the intervention group (11.7%) compared to the control-group (7.6%, p = 0.084). Differences among hospitals in both groups were not statistically different for mortality (p = 0.174), ICU stays (p = 0.174), and length of stay (p = 0.652) from pre- to implementation period. The intervention to facilitate timely sepsis care did not improve patient outcomes among those with severe sepsis or septic shock.
