MRC-ICU 2.0 boosts prediction accuracy for ICU outcomes.
Medication regimen complexity in the Intensive Care Unit (ICU) can impact patient outcomes and pharmacist workload, necessitating improved predictive models. The updated MRC-ICU 2.0 score demonstrated improved predictive ability over the original, with Area Under the Receiver Operating Characteristic (AUROC) increases of +0.03 to +0.08. MRC-ICU 2.0 offers complementary predictive value to severity-of-illness scores like Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA), enhancing decision-making in critical care. MRC-ICU 2.0 improves medication regimen complexity prediction and adds value when combined with other assessment tools in the ICU.
