Electronic Sepsis Screening Among Patients Admitted to Hospital Wards: A Stepped-Wedge Cluster Randomized Trial

Design, Setting, And Participants: In a stepped-wedge, cluster randomized trial at 5 hospitals in Saudi Arabia, 45 wards (clusters) were randomized into 9 sequences, 5 wards each, to have sepsis screening implemented at 2-month periods. The study was conducted between October 1, 2019, and July 31, 2021, with follow-up through October 29, 2021.

Intervention: An electronic alert, based on the quick Sequential Organ Failure Assessment score, was implemented in the electronic medical record in a silent mode that was activated to a revealed mode for sepsis screening.

Main Outcomes And Measures: The primary outcome was 90-day in-hospital mortality. There were 11 secondary outcomes, including code blue activation, vasopressor therapy, incident kidney replacement therapy, multidrug-resistant organisms, and Clostridioides difficile.

Results: Among 60 055 patients, 29 442 were in the screening group and 30 613 in the no screening group. They had a median age of 59 years (IQR, 39-68), and 30 596 were male (51.0%). Alerts occurred in 4299 of 29 442 patients (14.6%) in the screening group and 5394 of 30 613 (17.6%) in the no screening group. Within 12 hours of the alert, patients in the screening group were more likely to have serum lactate tested (adjusted relative risk [aRR], 1.30; 95% CI, 1.16-1.45) and intravenous fluid ordered (aRR, 2.17; 95% CI, 1.92-2.46) compared with those in the no screening group. In the primary outcome analysis, electronic screening resulted in lower 90-day in-hospital mortality (aRR, 0.85; 95% CI, 0.77-0.93; P < .001). Screening reduced vasopressor therapy and multidrug-resistant organisms but increased code blue activation, incident kidney replacement therapy, and C difficile.

Conclusions And Relevance: Among hospitalized ward patients, electronic sepsis screening compared with no screening resulted in significantly lower in-hospital 90-day mortality.
