Objective:To estimate the prevalence of chronic conditions among children admitted to U.S. pediatric intensive care units and to assess whether patients with complex chronic conditions experience pediatric intensive care unit mortality and prolonged length of stay risk beyond that predicted by commonly used severity-of-illness risk-adjustment models. Design, Setting, and Patients:Retrospective cohort analysis of 52,791 pediatric admissions to 54 U.S. pediatric intensive care units that participated in the Virtual Pediatric Intensive Care Unit Systems database in 2008. Measurements:Hierarchical logistic regression models, clustered by pediatric intensive care unit site, for pediatric intensive care unit mortality and length of stay >15 days. Standardized mortality ratios adjusted for severity-of-illness score alone and with complex chronic conditions. Main Results:Fifty-three percent of pediatric intensive care unit admissions had complex chronic conditions, and 18.5% had noncomplex chronic conditions. The prevalence of these conditions and their organ system subcategories varied considerably across sites. The majority of complex chronic condition subcategories were associated with significantly greater odds of pediatric intensive care unit mortality (odds ratios 1.25–2.9, all p values < .02) compared to having a noncomplex chronic condition or no chronic condition, after controlling for age, gender, trauma, and severity-of-illness. Only respiratory, gastrointestinal, and rheumatologic/orthopedic/psychiatric complex chronic conditions were not associated with increased odds of pediatric intensive care unit mortality. All subcategories were significantly associated with prolonged length of stay. All noncomplex chronic condition subcategories were either not associated or were negatively associated with pediatric intensive care unit mortality, and most were not associated with prolonged length of stay, compared to having no chronic conditions. Among this group of pediatric intensive care units, adding complex chronic conditions to risk-adjustment models led to greater model accuracy but did not substantially change unit-level standardized mortality ratios. Conclusions:Children with complex chronic conditions were at greater risk for pediatric intensive care unit mortality and prolonged length of stay than those with no chronic conditions, but the magnitude of risk varied across subcategories. Inclusion of complex chronic conditions into models of pediatric intensive care unit mortality improved model accuracy but had little impact on standardized mortality ratios.

OBJECTIVE To describe outcomes and causes of death in children on chronic positive-pressure ventilation via tracheostomy. STUDY DESIGN We conducted a retrospective observational cohort analysis of 228 children enrolled in an university-affiliated home mechanical ventilation (HMV) program over 22 years (990 person-years). Cumulative incidences of survival and liberation from HMV are presented. Time-to-events were compared by reason for chronic respiratory failure (CRF) and age and date of HMV initiation with Kaplan-Meier and Cox regression analyses. Circumstances of death are described. RESULTS Of our cohort, 47 of 228 children died, and 41 children were liberated from HMV. The 5-year cumulative incidences of survival and liberation were 80% and 24%, respectively. Being placed on HMV for chronic pulmonary disease was independently associated with liberation from HMV (hazard ratio, 7.38; 95% CI, 3.0-18.2; P < .001). Neither age nor reasons for CRF were associated with shortened survival. Progression of underlying condition accounted for only 34% of deaths; 49% of deaths were unexpected. CONCLUSION Most children on HMV survive or were weaned off. However, a sizable number of children in our cohort died, and many deaths were unexpected and from causes not directly related to their primary reason for CRF.

OBJECTIVE: To assess variation among hospitals on pediatric readmission and revisit rates and to determine the number of high- and low-performing hospitals. METHODS: In a retrospective analysis using the State Inpatient and Emergency Department Databases from the Healthcare Cost and Utilization Project with revisit linkages available, we identified pediatric (ages 1–20 years) visits with 1 of 7 common inpatient pediatric conditions (asthma, dehydration, pneumonia, appendicitis, skin infections, mood disorders, and epilepsy). For each condition, we calculated rates of all-cause readmissions and rates of revisits (readmission or presentation to the emergency department) within 30 and 60 days of discharge. We used mixed logistic models to estimate hospital-level risk-standardized 30-day revisit rates and to identify hospitals that had performance statistically different from the group mean. RESULTS: Thirty-day readmission rates were low (<10.0%) for all conditions. Thirty-day rates of revisit to the inpatient or emergency department setting ranged from 6.2% (appendicitis) to 11.0% (mood disorders). Study hospitals (n = 958) had low condition-specific visit volumes (37.0%–82.8% of hospitals had <25 visits). The only condition with >1% of hospitals labeled as different from the mean on 30-day risk-standardized revisit rates was mood disorders (4.2% of hospitals [n = 15], range of hospital performance 6.3%–15.9%). CONCLUSIONS: We found that when comparing hospitals’ performances to the average, few hospitals that care for children are identified as high- or low-performers for revisits, even for common pediatric diagnoses, likely due to low hospital volumes. This limits the usefulness of condition-specific readmission or revisit measures in pediatric quality measurement.

Objectives:To determine the rate of unplanned PICU readmissions, examine the characteristics of index admissions associated with readmission, and compare outcomes of readmissions versus index admissions. Design:Retrospective cohort analysis. Setting:Ninety North American PICUs that participated in the Virtual Pediatric Intensive Care Unit Systems. Patients:One hundred five thousand four hundred thirty-seven admissions between July 2009 and March 2011. Interventions:None. Measurements and Main Results:Unplanned PICU readmission within 48 hours of index discharge was the primary outcome. Summary statistics, bivariate analyses, and mixed-effects logistic regression model with random effects for each hospital were performed.There were 1,161 readmissions (1.2%). The readmission rate varied among PICUs (0–3.3%), and acute respiratory (56%), infectious (35%), neurological (28%), and cardiovascular (20%) diagnoses were often present on readmission. Readmission risk increased in patients with two or more complex chronic conditions (adjusted odds ratio, 1.72; p < 0.001), unscheduled index admission (adjusted odds ratio, 1.37; p < 0.001), and transfer to an intermediate unit (adjusted odds ratio, 1.29; p = 0.004, compared with ward). Trauma patients had a decreased risk of readmission (adjusted odds ratio, 0.67; p = 0.003). Gender, race, insurance, age more than 6 months, perioperative status, and nighttime transfer were not associated with readmission. Compared with index admissions, readmissions had longer median PICU length of stay (3.1 vs 1.7 d, p < 0.001) and higher mortality (4% vs 2.5%, p = 0.002). Conclusions:Unplanned PICU readmissions were relatively uncommon, but were associated with worse outcomes. Several patient and admission characteristics were associated with readmission. These data help identify high-risk patient groups and inform risk-adjustment for standardized readmission rates.

Infants and children with surgically corrected or palliated congenital heart disease (CHD) are at risk for chronic respiratory failure, necessitating home mechanical ventilation (HMV) via tracheostomy. However, very little data exists on this population or their outcomes. We conducted a retrospective chart review of all children with CHD enrolled in the Childrens Hospital Los Angeles HMV program between 1994 and 2009. Data were collected on type of heart lesion, surgeries performed, number of failed extubations, timing of tracheostomy, mortality, length of time on HMV, weaning status, associated co‐morbidities, and Risk Adjusted classification for Congenital Heart Surgery (RACHS‐1) category. Thirty‐five children were identified; six with single ventricle anatomy, who received palliative procedures. Twenty‐three (66%) patients are alive; 8 (23%) living patients have been weaned off HMV. Twelve (34%) patients are deceased. The incidence of mortality for single ventricle patients was 50%, and only one of the surviving children has received final palliation and weaned off HMV. Eight of nine patients (89%) with a RACHS score ≥4 died, and none have been weaned off of HMV. The 5‐year survival for all CHD HMV patients was 68%; 90% for patients with RACHS ≤3; and 12% for patients with score ≥4. Children with more complex lesions, as demonstrated by single ventricle physiology or greater RACHS scores, had higher mortality rates and less success weaning off HMV. This case series suggests that caregivers should give serious consideration to the type of heart defect as they advise families considering HMV in children with CHD.

Hospitalizing clinically stable patients in critical care settings results in unnecessary healthcare costs and thwarts timely patient throughput. Some pediatric hospitals care for their stable ventilator‐dependent children outside of pediatric intensive care units (PICUs). To date, no analysis of the costs of these pediatric ventilator units compared to PICUs has been performed. We conducted a retrospective comparison of PICU and ventilator ward costs of hospitalizations for 103 admissions in which ventilator‐dependent children served as their own matched controls between 2004 and 2007. For included admissions, patients were hospitalized in both units during the same admission and spent more than 1 day in their initial unit. Comparisons of costs were made using the last full PICU day and first full ward day. For the study period, the mean PICU cost of hospitalization per day was

3,565 (standard deviation [SD] ± 716.50). The mean ward cost was

2,052 (SD ± 617). The mean PICU cost was significantly larger than the mean ward cost (paired t‐test, P < 0.0001). Ventilator ward total and variable costs were significantly less than those in the PICU, and such units represent a potential cost saving measure for hospitals that care for ventilator‐dependent children.

BACKGROUND Bundles and checklists have been shown to decrease the rates of central line-associated bloodstream infections (CLABSIs), but implementation of these practices and association with CLABSI rates have not been described nationally. We describe implementation and levels of compliance with preventive practices in a sample of US neonatal intensive care units (NICUs) and assess their association with CLABSI rates. METHODS An online survey assessing infection prevention practices was sent to hospitals participating in National Healthcare Safety Network CLABSI surveillance in October 2011. Participating hospitals permitted access to their NICU CLABSI rates. Multivariable regressions were used to test the association between compliance with NICU-specific CLABSI prevention practices and corresponding CLABSI rates. RESULTS Overall, 190 level II/III and level III NICUs participated. The majority of NICUs had written policies (84%-93%) and monitored compliance with bundles and checklists (88%-91%). Reporting ≥95% compliance for any of the practices ranged from 50%-63%. Reporting of ≥95% compliance with insertion checklist and assessment of daily line necessity were significantly associated with lower CLABSI rates (P < .05). CONCLUSIONS Most of the NICUs in this national sample have instituted CLABSI prevention policies and monitor compliance, although reporting compliance ≥95% was suboptimal. Reporting ≥95% compliance with select CLABSI prevention practices was associated with lower CLABSI rates. Future studies should focus on identifying and improving compliance with effective CLABSI prevention practices in neonates.
