Nephrotoxin Induced Acute Kidney Injury (NAKI)
Exposure to nephrotoxic medications is common in hospitalized children. Nephrotoxin Induced Acute Kidney Injury (NAKI) is an injury to the kidney which develops within 2 days of exposure to nephrotoxic medications. We have a program to monitor for the development of NAKI.
What is Nephrotoxic Induced Acute Kidney Injury (NAKI)?
- NAKI is injury to the kidney which develops within 2 days of exposure to nephrotoxic medications.
Why is NAKI Important?
- AKI leads to increased hospital stay, increased cost, and chronic kidney disease.
NAKI Prevention for Healthcare Providers
How common is NAKI?
- Over 80% of hospitalized pediatric patients are exposed to at least one nephrotoxic medication (NTMx).
- NTMx exposure is one of the most common causes of Acute Kidney Injury (AKI) in non-critically ill hospitalized children.
- Children with high NTMx exposure (IV Aminoglycosides or vancomycin for >3 days OR >3 NTMx in a single day) develop Acute Kidney Injury (AKI) 25% of the time.
Which Patients Are at Risk?
Patients who are at risk for NAKI have received any of the following:
- ≥3 NTMx in a single day
- ≥3 days of an IV aminoglycoside or vancomycin
- 2 NTMx in a single day + exposure to iodinated contrast within the preceding 7 days

How is Golisano Children’s Hospital Preventing NAKI?
- GCH is participating in a national Quality Initiative Project to prevent NAKI by identifying patients at risk and monitoring daily creatinine in those patients.
How Do We Monitor for NAKI?
- For at risk patients, pharmacists will contact covering provider and recommend serum creatinine monitoring during the exposure period and for 48 hours after the exposure stops.
- If AKI is identified, serum creatinine should be monitored daily until back to baseline for 48 hours.
What Do YOU as Prescribers Have To Do?
- Consider ordering the daily serum creatinine when recommended by pharmacy.
- Consider withdrawing nephrotoxic medications based on recommendations of pharmacy.
- Discuss possible nephrotoxicity of medication regimen on daily rounds.
Do We Have Evidence That This Initiative Works?
- After 1 year, Cincinnati Children’s observed a 42% reduction in days with NAKI per 100 days of NTMx exposure.
- This most likely resulted from earlier AKI detection and withdrawal of NTMx.
