Journal ArticleDOI
Prediction of Sepsis in the Intensive Care Unit With Minimal Electronic Health Record Data: A Machine Learning Approach.
Thomas Desautels,Jacob Calvert,Jana Hoffman,Melissa Jay,Yaniv Kerem,Lisa Shieh,David Shimabukuro,Uli K. Chettipally,Feldman,Christopher Barton,David J. Wales,Ritankar Das +11 more
TL;DR: InSight, a machine learning classification system that uses multivariable combinations of easily obtained patient data, is an effective tool for predicting sepsis onset and performs well even with randomly missing data.
Journal ArticleDOI
Multicentre validation of a sepsis prediction algorithm using only vital sign data in the emergency department, general ward and ICU
Qingqing Mao,Melissa Jay,Jana Hoffman,Jacob Calvert,Christopher Barton,David Shimabukuro,Lisa Shieh,Uli K. Chettipally,Grant S. Fletcher,Yaniv Kerem,Yifan Zhou,Ritankar Das +11 more
TL;DR: InSight is robust to missing data, can be customised to novel hospital data using a small fraction of site data and retains strong discrimination across all institutions.
Journal ArticleDOI
A computational approach to early sepsis detection
Jacob Calvert,Daniel Alan Price,Uli K. Chettipally,Christopher Barton,Mitchell D. Feldman,Jana Hoffman,Melissa Jay,Ritankar Das +7 more
TL;DR: Sepsis can be predicted at least three hours in advance of onset of the first five hour SIRS episode, using only nine commonly available vital signs, with better performance than methods in standard practice today.
Journal ArticleDOI
Immediate and Delayed Traumatic Intracranial Hemorrhage in Patients With Head Trauma and Preinjury Warfarin or Clopidogrel Use
Daniel K. Nishijima,Steven R. Offerman,Dustin W. Ballard,David R. Vinson,Uli K. Chettipally,Adina S. Rauchwerger,Mary E. Reed,James F. Holmes +7 more
TL;DR: Although there may be unmeasured confounders that limit intergroup comparison, patients receiving clopidogrel have a significantly higher prevalence of immediate traumatic intracranial hemorrhage compared with patients receiving warfarin.
Journal ArticleDOI
Prediction of Acute Kidney Injury With a Machine Learning Algorithm Using Electronic Health Record Data.
Hamid Mohamadlou,Anna Lynn-Palevsky,Christopher Barton,Uli K. Chettipally,Lisa Shieh,Jacob Calvert,Nicholas Saber,Ritankar Das +7 more
TL;DR: The results of these experiments suggest that a machine learning–based AKI prediction tool may offer important prognostic capabilities for determining which patients are likely to suffer AKI, potentially allowing clinicians to intervene before kidney damage manifests.
