Effect of a Sepsis Prediction Algorithm on Patient Mortality, Length of Stay, and Readmission

Abstract: KEY POINTSQuestion: Is a machine learning algorithm capable of accurate severe sepsis prediction, and does its clinical implementation improve patient mortality rates, hospital length of stay, and 30-day readmission rates?Findings: In a retrospective analysis that included datasets containing a total of 585,644 patient encounters from 461 hospitals, the machine learning algorithm demonstrated an AUROC of 0.93 at time of severe sepsis onset, which exceeded those of MEWS (0.71), SOFA (0.74), and SIRS (0.62); and… Show more

“…Alert volumes varied as site-specific customisation was performed through PDSA (plan-do-study-act) cycles for thresholding and rules-based suppression to optimise the algorithm for the best fit into a given care setting. 51 In particular, for any patient for whom an alert had already been produced, additional alerts were uniformly suppressed. At four of the nine hospitals, we collected data prior to the implementation of the MLA for measurement of baseline outcomes and for training of the MLA once deployed.…”
