Background Initiation of continuous kidney replacement therapy (CKRT) greater than 20% fluid overload is associated with increased morbidity and mortality. We aimed to reduce the number of patients initiated on CKRT greater than 20% fluid overload by 50% in one year by implementation of a quality improvement initiative. Methods This is a prospective quality improvement study set in a pediatric ICU of an urban children's hospital of patients initiated on CKRT over 2 years. The intervention included creation of an electronic health record order for daily calculation of net percent fluid overload, incorporation into daily rounds, and education programs tailored to physicians and bedside nursing. We measured adherence with the new order set, percent fluid overload at CKRT initiation, days on CKRT, timing of first nephrology consultation, and death prior to discharge. Results A total of 32% of patients were initiated on CKRT greater than 20% fluid overload pre-initiative and 9% post-initiative, a 72% reduction over 13 months. Patients initiated on CKRT greater than 20% fluid overload had median CKRT course of 8 (IQR 4-14) vs. 22 days (IQR 13.5-62). Conclusion Creating a system using EHR with education may reduce initiation of CKRT after development of severe fluid overload.

Background Continuous kidney replacement therapy (CKRT) is a mainstay of therapy for management of severe acute kidney injury (AKI) in critically ill pediatric patients. There is limited data on the risk of chronic kidney disease (CKD) after discharge in this population. Methods This is a single-center, retrospective cohort study of all pediatric patients ages 0-17 years who received CKRT from 2013 to 2017. The study excluded patients with pre-existing CKD, those who died prior to discharge, and those who had insufficient follow-up data. Patients were followed after hospital discharge and electronic health record data was collected and analyzed to assess for incidence of and risk factors for kidney sequelae. Results A total of 42 patients were followed at a median time of 27 months (IQR 17.2, 39.8). Of these, 26.2% had evidence of CKD and 19% were at risk for CKD. Lower eGFR at hospital discharge was associated with increased odds of kidney sequelae (aOR 0.985; 95% CI 0.972, 0.996). Ages 0- < 1 and 12-17 were not significantly different (aOR 0.235, 95% CI 0.024, 1.718) and had the highest incidence of kidney sequelae (50% and 77%, respectively). Ages 1-5 and 6-11 had a decreased odds of kidney sequelae compared to the 12-17 year age group (aOR 0.098; 95% CI 0.009, 0.703 and aOR 0.035; 95% CI 0.001, 0.39, respectively). Only 54.8% of patients (n = 23) were seen in the nephrology clinic after discharge. Conclusions Patients who receive CKRT for AKI have a significant risk of CKD, while follow-up with a pediatric nephrologist in these high-risk patients is sub-optimal.

Background Immunosuppressed kidney transplant patients may have suboptimal response to vaccinations. The aim of this study was to determine antibody response to a quadrivalent meningococcal conjugate vaccine (MenACWY-D) in adolescents with a kidney transplant. Methods This was a prospective, single-center, cohort study. Adolescent patients (11-22 years old) with a functioning kidney transplant for at least 3 months and no previous meningococcal vaccination were eligible for enrollment. Antibody levels to all serogroups were measured before vaccination (baseline) and at 4 weeks and 1, 2 and 3 years after vaccination. Seropositivity was defined as a titer [greater than or equal to] 1:8 at baseline, and seroconversion as a fourfold or greater increase in antibody titer from baseline at 4 weeks post-vaccination. Geometric mean titers (GMTs) were calculated at each time point and compared to published GMTs from vaccinated healthy adolescents. Results Nineteen patients were enrolled. No patient had seroprotective titers against all four serogroups at baseline. At 4 weeks post-vaccination 41% of patients seroconverted to all four serogroups, with seroconversion rates of 88, 53, 71 and 94% for serogroups A, C, W and Y, respectively. GMTs were significantly lower in adolescents with a kidney transplant than in healthy adolescents at 1 month (p = 0.02) and 3 years (p = 0.04) post-vaccination. There were no significant adverse events, episodes of rejection or death in any patient. Conclusions Adolescents with a kidney transplant may not respond adequately to MenACWY-D and may experience more rapid declines in antibody titers than healthy adolescents. Further study is needed to determine if alternative dosing schedules can improve antibody response in this population., Author(s): Delphine R.
