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

Patient / Population Intervention / Exposure Comparison Outcome

In 60,055 patients admitted to 45 wards at five hospitals in Saudi Arabia, an electronic qSOFA-based sepsis alert in the medical record reduced 90-day in-hospital mortality compared with no screening (alert in silent mode).

Discussion & critique

The strongest randomised evidence that ward-level electronic sepsis screening saves lives, filling a gap in guidelines that recommended screening on limited evidence. A boundary case for this register: the alert is a rule-based qSOFA trigger, not a machine-learning model, so it tests the deployment pathway rather than AI. The stepped-wedge design cannot fully separate the intervention from secular trends, and the rise in code blue activation, kidney replacement therapy and C. difficile points to the cost of more aggressive treatment.
