Conditions
Brief summary
This is a retrospective study drawing on data from the Brigham and Women's Hospital Home Hospital Program's Database. Sociodemographic and clinical data from a training cohort were used to train a machine learning algorithm to predict blood potassium throughout a patient's admission. This algorithm was then validated in a validation cohort.
Interventions
OTHERPotassium estimation algorithm
Apply a machine learning algorithm to estimate a patient's potassium.
