NarxCare vs PrecisePK

A hospital pharmacist adjusting vancomycin doses in PrecisePK and a prescriber reading NarxCare's PDMP history are not weighing one tool against the other. PrecisePK works from a patient's measured vancomycin level, while NarxCare works from controlled-substance monitoring data. PrecisePK names Sharp and Dignity Health among its customers.

In an Oman study of 90 inpatients, PrecisePK's Rodvold posterior model had a relative bias of 0.47% and a relative RMSE of 13.18%, which the authors called clinically acceptable, against 20.17% bias for the DoseMeRx model they compared. NarxCare's Narx Scores and Overdose Risk Score come from a proprietary algorithm, and an NPJ Digital Medicine rebuild from its published specification reached precision of 0.01 to 0.32 against the reported 0.75, with F1 of 0.02 to 0.39 against 0.65.
