Summary of NINJA Studies

Citation Population Intervention Comparator Outcome Adaptations to NINJA
Goldstein 201335 Non-critically ill pediatric patients Pharmacists manually screened Monday to Friday to assess for patients with high NTM (initial screening was manual until an automated EHR-generated screening report was developed)
Daily SCr with substitution or therapeutic drug monitoring when possible
Evaluated project for 1 yr
Phase 1 (6 mo manual screening), phase 2 (6 mo automated)
N = 21,807 patients included with n = 729 NTM patients (945 total events)
AKI prevalence rate 25%
Rate of patient with high NTM exposure 31%
AKI intensity rate decreased by 42% with intervention
When automated screening implemented, captured more compared with manual screening (11.6 vs 7.6 rate of exposure per 1000 patient-days)
Original definition (aminoglycosides ≥ 3 days or ≥ 3 NTMs within 24 hr)
pRIFLE criteria used
Goldstein 201636 Non-critically ill pediatric patients Additional 3-yr follow-up to assess if improvement was sustained Compared with a priori standard of 8 consecutive weekly metric rates below the baseline rate (investigators assumed that initial baseline exposure rates would have persisted without project implementation) N = 1749 patients with 3243 episodes of NTM
exposure and N = 575 AKI occurrences
Exposure rate decreased by 38% and the AKI rate decreased by 64%
N = 633 exposures and 398 AKI episodes were avoided
KDIGO criteria used
Goldstein 202037 Non-critically ill pediatric patients at 9 centers Automated screening report to identify patients’ NTM exposure
Daily SCr during high NTM exposure and for 2 days post exposure or post-AKI resolution, whichever occurred last
N = 638,695 patients with 4513 episodes of NTM exposure and N= 746 AKI occurrences
Observed a significant and sustained 23.8% decrease in AKI in patients with high NTM exposure
KDIGO criteria used
Stoops 201911 Level IV NICU (neonates and infants) Automated screening report to identify patients with ≥3 NTMs within 24 hr or ≥4 calendar days of an IV aminoglycoside
Daily SCr during high NTM exposure and for 2 days post exposure or post-AKI resolution, whichever occurred last
Pre-implementation (6 mo) vs sustainability (18 mo) with 1-mo washout period N = 476 individual NTM exposure events with incidence of AKI 19.7% (n = 94/476)
Systematic identification and daily SCr screening in high risk patients prevented 100 AKI episodes in 18-mo period
Reduction in NTM exposures from 16.4 to 9.6 per 1000 patient-days(p = 0.03), reduction in percentage of NTM-AKI from 30.9% to 11% (p < .001), and reduction in AKI intensity from 9.1 to 2.9 per 100 susceptible patient-days (p < .001) while maintaining a high SCr surveillance rate.
Extension of IV aminoglycoside from 3 days to 4 or more days
Definition of baseline SCr (first 14 days of life follow trends, after 14 days of life compare with lowest previous value)
Semi-automated reporting system
KDIGO criteria used
Newton 202132 Cystic fibrosis patients (0 to 21 yr) Automated screening report to identify patients with ≥3 NTMs within 24 hr or ≥4 calendar days of an IV aminoglycoside or vancomycin SCr screening 3 days a week in patients at high risk Pre-implementation (4 mo) vs sustainability (4 mo) with no washout period N = 19 patients with 25 NTM exposure events
Increased SCr monitoring uncovered more episodes of AKI in the post-implementation phase
Used the pRIFLE criteria SCr screening 3 times weekly (Monday, Wednesday, Friday)
