Objectives: The objective of this study is to describe the relative frequency of use of continuous renal replacement therapy, intermittent hemodialysis, and peritoneal dialysis and to analyze characteristics and outcomes of critically ill children receiving renal replacement therapies admitted to PICUs that participate in the Virtual PICU (VPS LLC, Los Angeles, CA) registry. Design: Retrospective, database analysis. Setting: PICUs that participate in the Virtual PICU (VPS LLC) registry. Patients: Critically ill children admitted to PICUs that participate in the Virtual PICU (VPS LLC) registry and received renal replacement therapy from January 1, 2009, to December 31, 2015. Interventions: None. Measurements and Main Results: A total of 7,109 cases (53% males) received renal replacement therapy during the study period. The median age was 72.3 months (interquartile range, 8.4–170 mo) and median length of stay was 8.7 days (interquartile range, 3.3–21.2 d). Caucasians comprised 42% of the cohort and blacks and Hispanics were 16% each. Continuous renal replacement therapy was used in 46.5%, hemodialysis in 35.5% and peritoneal dialysis in 18%. Of the 7,109 cases, 1,852 (26%) were postoperative cases (68% cardiac surgical) and 981 (14%) had a diagnosis of cancer. Conventional mechanical ventilation was used in 64%, high-frequency oscillatory ventilation in 12%, noninvasive ventilation in 24%, and extracorporeal membrane oxygenation in 5.8%. The overall mortality was 22.3%. Patients who died were younger 40.8 months (interquartile range, 1.5–159.4 mo) versus 79.9 months (interquartile range, 12.6–171.7 mo), had a longer length of stay 15 days (interquartile range, 7–33 d) versus 7 days (interquartile range, 3–18 d) and higher Pediatric Index of Mortality 2 score –2.84 (interquartile range, –3.5 to –1.7) versus –4.2 (interquartile range, –4.7 to –3.0) (p < 0.05). On multivariate logistic regression analysis, higher mortality was associated with the presence of cancer (32.7%), previous ICU admission (32%), requiring mechanical ventilation (33.7%), receiving high-frequency oscillatory ventilation (67%), or extracorporeal membrane oxygenation (58.4%), admission following cardiac surgical procedure (29.4%), and receiving continuous renal replacement therapy (38.8%), and lower mortality was associated with hemodialysis (9.8%), and peritoneal dialysis (12.3%) (p < 0.0001). Conclusions: Continuous renal replacement therapy is an increasingly prevalent renal replacement therapy modality used in critically ill children admitted to an ICU. Higher mortality rate with the use of continuous renal replacement therapy should be interpreted with caution.
Children may visit the emergency department (ED) regularly in part because they and their caregivers may be experiencing barriers to appropriate and timely pediatric care. However, assessing the wide range of potential barriers to access to care that children and their caregivers may experience is often a challenge. The objective of this study was to assess the barriers to pediatric health care reported by caregivers and to examine the association between those reported barriers to care with the frequency of children's ED visits in the past 12 months. Assessment of ED utilization and access to care barriers was made through a telephone interview survey conducted as part of a broader Community Health Needs Assessment in 2015. A weighted community sample of adult caregivers (N = 1057) of children between the ages of 0-17 residing in Miami-Dade, Broward, and Palm Beach counties, Florida were contacted. This study found that multiple ED visits (≥2 vs. 0) in the past 12 months by a child were most strongly associated with access to care barriers attributed to language and culture (relative risk [RR] = 2.51), trouble finding a doctor (RR = 1.86), scheduling an appointment (RR = 1.68), and transportation access (RR = 1.73). These findings suggest that access to care barriers experienced by households may exacerbate the risk of a child experiencing repeated visits to the ED in a year. Findings are discussed further in the context of actionable population health management strategies to reduce risk of frequent ED utilization by children.
Accurately predicting and reducing risk of unplanned readmissions (URs) in pediatric care remains difficult. We sought to develop a set of accurate algorithms to predict URs within 3, 7, and 30 days of discharge from inpatient admission that can be used before the patient is discharged from a current hospital stay. METHODS:We used the Children's Hospital Association Pediatric Health Information System to identify a large retrospective cohort of 1 111 323 children with 1 321 376 admissions admitted to inpatient care at least once between January 1, 2016, and December 31, 2017. We used gradient boosting trees (XGBoost) to accommodate complex interactions between these predictors. RESULTS:In the full cohort, 1.6% of patients had at least 1 UR in 3 days, 2.4% had at least 1 UR in 7 days, and 4.4% had at least 1 UR within 30 days. Prediction model discrimination was strongest for URs within 30 days (area under the curve [AUC] 5 0.811; 95% confidence interval [CI]: 0.808-0.814) and was nearly identical for UR risk prediction within 3 days (AUC 5 0.771; 95% CI: 0.765-0.777) and 7 days (AUC 5 0.778; 95% CI: 0.773-0.782), respectively. Using these prediction models, we developed a publicly available pediatric readmission risk scores prediction tool that can be used before or during discharge planning.CONCLUSIONS: Risk of pediatric UR can be predicted with information known before the patient's discharge and that is easily extracted in many electronic medical record systems. This information can be used to predict risk of readmission to support hospital-discharge-planning resources.
