AIMS: To compute the financial and mortality impact of InSight, an algorithm-driven biomarker, which forecasts the onset of sepsis with minimal use of electronic health record data.
METHODS: We compare InSight with existing sepsis screening tools and compute the differential life and cost savings associated with its use in the inpatient setting. To do so, we obtain mortality reduction from an increase in the number of sepsis cases correctly identified by InSight. Early sepsis detection by InSight is also associated with a reduction in length-of-stay, from which we directly compute cost savings.
RESULTS: InSight identifies more true positive cases of severe sepsis, with fewer false alarms, than comparable methods. For an individual ICU with 50 beds, for example, we determine that InSight annually saves 75 additional lives and reduces sepsis related costs by $560,000.
LIMITATIONS: InSight performance results are derived from analysis of a single-center cohort. Mortality reduction results rely on a simplified use case, which fixes prediction times at 0, 1, and 2 hours before sepsis onset, likely leading to underestimates of lives saved. The corresponding cost reduction numbers are based on national averages for daily patient length-of-stay cost.
CONCLUSIONS: InSight has the potential to reduce sepsis-related deaths and to lead to substantial cost savings for healthcare facilities.
