Background: Many recommendations regarding peritonitis prevention in international consensus guidelines are opinion-based rather than evidence-based. The aim of this study was to examine the impact of peritoneal dialysis (PD) catheter insertion technique, timing of gastrostomy placement, and use of prophylactic antibiotics prior to dental, gastrointestinal, and genitourinary procedures on the risk of peritonitis in pediatric patients on PD. Methods: We conducted a retrospective cohort study of pediatric patients on maintenance PD using data from the SCOPE collaborative from 2011 to 2022. Data pertaining to laparoscopic PD catheter insertion (vs. open), gastrostomy placement after PD catheter insertion (vs. before/concurrent), and no prophylactic antibiotics (vs. yes) were obtained. Multivariable generalized linear mixed modeling was used to assess the relationship between each exposure and occurrence of peritonitis. Results: There was no significant association between PD catheter insertion technique and development of peritonitis (aOR = 2.50, 95% CI 0.64–9.80, p = 0.19). Patients who had a gastrostomy placed after PD catheter insertion had higher rates of peritonitis, but the difference was not statistically significant (aOR = 3.19, 95% CI 0.90–11.28, p = 0.07). Most patients received prophylactic antibiotics prior to procedures, but there was no significant association between prophylactic antibiotic use and peritonitis (aOR = 1.74, 95% CI 0.23–13.11, p = 0.59). Conclusions: PD catheter insertion technique does not appear to have a significant impact on peritonitis risk. Timing of gastrostomy placement may have some impact on peritonitis risk. Further study must be done to clarify the effect of prophylactic antibiotics on peritonitis risk. [ABSTRACT FROM AUTHOR]

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: In its first 3 years, the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) Collaborative demonstrated a statistically significant increase in the likelihood of compliance with a standardized follow-up care bundle and a significant reduction in peritonitis. We sought to determine if compliance with care bundles and low peritonitis rates could be sustained in centers continuously participating for 84 months. Methods: Centers that participated from collaborative launch through the 84-month study period and provided pre-launch peritonitis rates were included. Children on maintenance peritoneal dialysis were eligible for enrollment. Changes in bundle compliance were assessed using a logistic regression model or a generalized linear mixed model (GLMM). Changes in average annualized peritonitis rates over time were modeled using GLMMs. Results: Nineteen centers contributed 1055 patients with 1268 catheters and 17,247 follow-up encounters. The likelihood of follow-up compliance increased significantly over the study period (OR 1.05 95% confidence interval (CI) 1.03, 1.07; p < 0.001). Centers achieved ≥ 80% follow-up bundle compliance by 28 months and maintained a mean compliance of 84% between 28 and 84 months post-launch. Average monthly peritonitis rates decreased from 0.53 (95% CI 0.37, 0.70) infections per patient-year pre-launch to 0.30 (95% CI 0.23, 0.43) at 84 months post-launch, p < 0.001. Conclusions: Centers participating in the SCOPE Collaborative for 84 months achieved and maintained a high level of compliance with a standardized follow-up care bundle and demonstrated a significant and continued reduction in average monthly peritonitis rates.
