Nomogram Predicts Suboptimal CRRT Downtime in Critically Ill Patients
This retrospective model-building study identifies five bedside-modifiable factors driving continuous renal replacement therapy interruptions, relevant to pharmacists managing drug dosing and anticoagulation across dialysis circuits.
CRRT downtime risks can now be predicted and mitigated in the ICU.
Downtime during continuous renal replacement therapy (CRRT) can worsen patient outcomes, increasing the risk of mortality. The study identified five risk factors for downtime: filter replacements, agitation, plasma exchange, catheter dysfunction, and out-of-unit transport, with a nomogram showing good predictive accuracy (AUCs 0.789 to 0.835). ICU nurses can use this predictive model to pinpoint high-risk CRRT days, improving patient management and reducing adverse events related to excessive downtime. Identifying and managing risks for CRRT downtime can enhance treatment efficacy and patient care in the ICU.
