A prospective multi-center quality improvement initiative (NINJA) indicates a reduction in nephrotoxic acute kidney injury in hospitalized children.

Nephrotoxic medication (NTMx) exposure is a common cause of acute kidney injury (AKI) in hospitalized children. The Nephrotoxic Injury Negated by Just-in time Action (NINJA) program decreased NTMx associated AKI (NTMx-AKI) by 62% at one center. To further test the program, we incorporated NINJA across nine centers with the goal of reducing NTMx exposure and, consequently, AKI rates across these centers. NINJA screens all non-critically ill hospitalized patients for high NTMx exposure (over three medications on the same day or an intravenous aminoglycoside over three consecutive days), and then recommends obtaining a daily serum creatinine level in exposed patients for the duration of, and two days after, exposure ending. Additionally, substitution of equally efficacious but less nephrotoxic medications for exposed patients starting the day of exposure was recommended when possible. The main outcome was AKI as defined by the Kidney Disease Improving Global Outcomes (KDIGO) serum creatinine criteria (increase of 50% or 0.3 mg/dl over baseline). The primary outcome measure was AKI episodes per 1000 patient-days. Improvement was defined by statistical process control methodology and confirmed by Autoregressive Integrated Moving Average (ARIMA) modeling. Eight consecutive bi-weekly measure rates in the same direction from the established baseline qualified as special cause change for special process control. We observed a significant and sustained 23.8% decrease in NTMx-AKI rates by statistical process control analysis and by ARIMA modeling; similar to those of the pilot single center. Thus, we have successfully applied the NINJA program to multiple pediatric institutions yielding decreased AKI rates.

Impact of standardized protocols for cytomegalovirus disease prevention in pediatric solid organ transplant recipients.

End-organ disease caused by CMV is a significant cause of morbidity and mortality in pediatric SOT recipients. Pediatric transplant centers have adopted various approaches for CMV disease prevention in this patient population. We observed significant practice variation in CMV testing, prophylaxis, and surveillance across SOT groups in our center. To address this, we implemented evidence-based standardized protocols and measured outcomes pre- and post-implementation of these protocols. We performed retrospective chart review for SOT recipients from 2009 to 2014 at Boston Children's Hospital. Using descriptive statistics, we measured practice improvement in provision of appropriate prophylaxis, occurrence of neutropenia and associated complications, and occurrence of CMV DNAemia and CMV disease pre- and post-intervention. The pre- and post-intervention periods included 141 and 109 patients, respectively. With the exception of kidney transplant recipients, provision of appropriate valganciclovir prophylaxis improved across SOT groups post-intervention (P < .01). Occurrence of >1 episode of neutropenia was greater in the preintervention period (30% vs 10%, P < .001). In both periods, neutropenia was associated with few episodes of invasive infections. The occurrence of CMV disease did not differ and was overall low. However, due to routine surveillance a significantly greater number of asymptomatic CMV DNAemia episodes were identified and treated in the post-intervention period. Implementation of standardized prevention protocols helped to improve the provision of appropriate prophylaxis to patients at risk for CMV acquisition, increased the diagnosis and treatment of asymptomatic CMV DNAemia, and decreased episodes of recurrent neutropenia in patients receiving prophylaxis.

Efficacy and economic evaluation of a volume-based cathflo activase protocol versus a fixed-dose alteplase protocol for catheter occlusions in pediatric patients.

OBJECTIVES: This prospective study evaluated the efficacy and economic benefit of Cathflo Activase and a volume-dependent protocol versus a previously utilized fixed-dose 2 mg/mL alteplase aliquot protocol for central venous catheter clearance in pediatric patients. METHODS: All pediatric patients with a medically diagnosed catheter occlusion were eligible for inclusion into this study. Retrospective data was analyzed from an approved data collection form, which had been implemented during the utilization of the alteplase protocol. Data collection indicators included catheter type, dose, dwell time, outcome of attempt (successful or unsuccessful), additional measures taken, and comments. A new protocol utilizing Cathflo Activase and manufacturer recommended volume-based dosing was prospectively implemented and data was collected and evaluated and compared to data from the alteplase protocol. RESULTS: Alteplase and Cathflo protocol data was evaluated for a total of 96 courses in 48 patients (0.09 - 22.8 years, 2.15 - 105.2 kg). Complete resolution was achieved in 69.6% of patients with the alteplase protocol, partial resolution was attained in 8.7%, and treatment failure occurred in 21.7% of patients. For the Cathflo Activase group, complete resolution was observed in 82% of occlusions, with 8% partial resolution and treatment failure of 10%. The average cost per dose utilized by our patients during this study was $49.68 and $30.56 for the alteplase and Cathflo Activase groups, respectively. CONCLUSIONS: Our data indicate that the Cathflo Activase protocol may be as efficacious as the previous alteplase protocol. Furthermore, there are added time and cost benefits.
