DESIGN: We conducted a secondary analysis of the Sepsis PRevalence, OUtcomes, and Therapies study. Data about PICU characteristics, patient demographics, therapies, and outcomes were compared. Multivariable regression models were used to determine adjusted differences in morbidity and mortality.
SETTING: European and U.S. PICUs.
PATIENTS: Children with severe sepsis managed in European and U.S. PICUs enrolled in the Sepsis PRevalence, OUtcomes, and Therapies study.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: European PICUs had fewer beds (median, 11 vs 24; p < 0.001). European patients were younger (median, 1 vs 6 yr; p < 0.001), had higher severity of illness (median Pediatric Index of Mortality-3, 5.0 vs 3.8; p = 0.02), and were more often admitted from the ward (37% vs 24%). Invasive mechanical ventilation, central venous access, and vasoactive infusions were used more frequently in European patients (85% vs 68%, p = 0.002; 91% vs 82%, p = 0.05; and 71% vs 50%; p < 0.001, respectively). Raw morbidity and mortality outcomes were worse for European compared with U.S. patients, but after adjusting for patient characteristics, there were no significant differences in mortality, multiple organ dysfunction, disability at discharge, length of stay, or ventilator/vasoactive-free days.
CONCLUSIONS: Children with severe sepsis admitted to European PICUs have higher severity of illness, are more likely to be admitted from hospital wards, and receive more intensive care therapies than in the United States. The lack of significant differences in morbidity and mortality after adjusting for patient characteristics suggests that the approach to care between regions, perhaps related to PICU bed availability, needs to be considered in the design of future international clinical trials in pediatric severe sepsis.
DESIGN: A single-center retrospective cross-sectional study.
SETTING: Tertiary referral PICU in Johor, Malaysia.
PATIENTS: All children admitted to the PICU over 8 years were included. Patients readmitted into PICU after the first PICU discharge during the hospitalization period were categorized into "early" (within 48 hr) and "late" (after 48 hr), and factors linked to the readmissions were identified. The mortality rate was determined and compared between no, early, and late readmission.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: There were 2,834 patients in the study with 70 early and 113 late readmissions. Therefore, the rate of early and late PICU readmission was 2.5% (95% CI, 1.9-3.0%) and 3.9% (95% CI, 3.2-4.7%), respectively. The median length of stay of the second PICU admission for early and late readmissions was 2.7 days (interquartile range, 1.1-7.0 d) and 3.2 days (interquartile range, 1.2-7.5 d), respectively. The majority of early and late readmissions had a similar diagnosis with their first PICU admission. Multivariable multinomial logistic regression revealed a Pediatric Index Mortality 2 score of greater than or equal to 15, chronic cardiovascular condition, and oxygen supplement upon discharge as independent risk factors for early PICU readmission. Meanwhile, an infant of less than 1 year old, having cardiovascular, other congenital and genetic chronic conditions and being discharged between 8 AM and 5 PM was an independent risk factor for late readmission. There was no significant difference in the mortality rate of early (12.9%), late (13.3%), and no readmission (10.7%).
CONCLUSIONS: Despite the lack of resources and expertise in lower- and middle-income countries, the rate and factors for PICU readmission are similar to those in high-income countries. However, PICU readmission has no statistically significant association with mortality.
DESIGN: Single-center retrospective observational study.
SETTING: Thirty-six-bed surgical/medical tertiary PICU.
PATIENTS: Children from birth to less than or equal to 16 years old admitted between 2015 and 2018.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Clinical data were extracted from the PICU clinical information system. Patients with baseline creatinine at admission greater than 20 micromol/L above the calculated normal creatinine level were classified as "high risk of acute kidney injury." Models were created to predict acute kidney injury at admission and on day 1. Out of the 7,505 children admitted during the study period, 738 patients (9.8%) were classified as high risk of acute kidney injury at admission and 690 (9.2%) developed acute kidney injury during PICU admission. Compared to Kidney Disease: Improving Global Outcomes criteria as the reference standard, high risk of acute kidney injury had a lower sensitivity and higher specificity compared with renal angina index greater than or equal to 8 on day 1. For the admission model, the adjusted odds ratio of developing acute kidney injury for high risk of acute kidney injury was 4.2 (95% CI, 3.3-5.2). The adjusted odds ratio in the noncardiac cohort for high risk of acute kidney injury was 7.3 (95% CI, 5.5-9.7). For the day 1 model, odds ratios for high risk of acute kidney injury and renal angina index greater than or equal to 8 were 3.3 (95% CI, 2.6-4.2) and 3.1 (95% CI, 2.4-3.8), respectively.
CONCLUSIONS: The relationship between high risk of acute kidney injury and acute kidney injury needs further evaluation. High risk of acute kidney injury performed better in the noncardiac cohort.
DESIGN: This pilot study over April 2016 to September 2019 adopts a before-and-after comparison design of a lung-protective mechanical ventilation protocol. All admissions to the PICU were screened daily for fulfillment of the Pediatric Acute Lung Injury Consensus Conference criteria and included.
SETTING: Multidisciplinary PICU.
PATIENTS: Patients with pediatric acute respiratory distress syndrome.
INTERVENTIONS: Lung-protective mechanical ventilation protocol with elements on peak pressures, tidal volumes, end-expiratory pressure to FIO2 combinations, permissive hypercapnia, and permissive hypoxemia.
MEASUREMENTS AND MAIN RESULTS: Ventilator and blood gas data were collected for the first 7 days of pediatric acute respiratory distress syndrome and compared between the protocol (n = 63) and nonprotocol groups (n = 69). After implementation of the protocol, median tidal volume (6.4 mL/kg [5.4-7.8 mL/kg] vs 6.0 mL/kg [4.8-7.3 mL/kg]; p = 0.005), PaO2 (78.1 mm Hg [67.0-94.6 mm Hg] vs 74.5 mm Hg [59.2-91.1 mm Hg]; p = 0.001), and oxygen saturation (97% [95-99%] vs 96% [94-98%]; p = 0.007) were lower, and end-expiratory pressure (8 cm H2O [7-9 cm H2O] vs 8 cm H2O [8-10 cm H2O]; p = 0.002] and PaCO2 (44.9 mm Hg [38.8-53.1 mm Hg] vs 46.4 mm Hg [39.4-56.7 mm Hg]; p = 0.033) were higher, in keeping with lung protective measures. There was no difference in mortality (10/63 [15.9%] vs 18/69 [26.1%]; p = 0.152), ventilator-free days (16.0 [2.0-23.0] vs 19.0 [0.0-23.0]; p = 0.697), and PICU-free days (13.0 [0.0-21.0] vs 16.0 [0.0-22.0]; p = 0.233) between the protocol and nonprotocol groups. After adjusting for severity of illness, organ dysfunction and oxygenation index, the lung-protective mechanical ventilation protocol was associated with decreased mortality (adjusted hazard ratio, 0.37; 95% CI, 0.16-0.88).
CONCLUSIONS: In pediatric acute respiratory distress syndrome, a lung-protective mechanical ventilation protocol improved adherence to lung-protective mechanical ventilation strategies and potentially mortality.
DESIGN: A multicenter retrospective study with longitudinal clinical data over 1, 6, 24, 48, and 72 hours of PICU admission. The primary outcome was PICU mortality. Multivariable logistic regression analysis was used to identify factors at PICU admission that were associated with mortality.
SETTING: Nine multidisciplinary PICUs in three Asian countries.
PATIENTS: Children with severe sepsis or septic shock admitted to the PICU from January to December 2017.
INTERVENTION: None.
MEASUREMENT AND MAIN RESULTS: A total of 271 children were included in this study. Median (interquartile range) age was 4.2 years (1.3-10.8 yr). Pneumonia (77/271 [28.4%]) was the most common source of infection. Majority of patients (243/271 [90%]) were resuscitated within the first hour, with fluid bolus (199/271 [73.4%]) or vasopressors (162/271 [59.8%]). Fluid resuscitation commonly took the form of normal saline (147/199 [74.2%]) (20 mL/kg [10-20 mL/kg] over 20 min [15-30 min]). The most common inotrope used was norepinephrine 81 of 162 (50.0%). Overall PICU mortality was 52 of 271 (19.2%). Improved hemodynamic variables (e.g., heart rate, blood pressure, and arterial lactate) were seen in survivors within 6 hours of admission as compared to nonsurvivors. In the multivariable model, admission severity score was associated with PICU mortality.
CONCLUSIONS: Mortality from pediatric severe sepsis and septic shock remains high in Asia. Consistent with current guidelines, most of the children admitted to these PICUs received fluid therapy and inotropic support as recommended.
DESIGN: Retrospective cohort analysis of children who underwent a systemic-to-pulmonary shunt after excluding those who had it for Norwood or Damus-Kaye-Stansel procedure.
SETTING: The Royal Children's Hospital, Melbourne, VIC, Australia.
PATIENTS: From 2008 to 2015, 201 children who had a systemic-to-pulmonary shunt were included.
INTERVENTIONS: Major adverse event is defined as one or more of cardiac arrest, chest reopening, or requirement for extracorporeal membrane oxygenation. Study outcome is a "composite poor outcome," defined as one or more of acute kidney injury, necrotizing enterocolitis, brain injury, or in-hospital mortality.
MEASUREMENTS AND MAIN RESULTS: Median (interquartile range) age was 12 days (6-38 d) and median (interquartile range) time to major adverse event was 5.5 hours (2-17 hr) after admission. Overall, 36 (18%) experienced a major adverse event, and reasons were over-shunting (n = 17), blocked shunt (n = 13), or other (n = 6). Fifteen (88%) in over-shunting group suffered a cardiac arrest compared with two (15%) in the blocked shunt group (p < 0.001). The composite poor outcome was seen in 15 (88%) in over-shunting group, four (31%) in the blocked shunt group, and 56 (34%) in those who did not experience a major adverse event (p < 0.001). By multivariable analysis, predictors for composite poor outcome were major adverse event due to over-shunting (no major adverse event-reference; over-shunting odds ratio, 18.60; 95% CI, 3.87-89.4 and shunt-block odds ratio, 1.57; 95% CI, 0.46-5.35), single ventricle physiology (odds ratio, 4.70; 95% CI, 2.34-9.45), and gestation (odds ratio, 0.84/wk increase; 95% CI, 0.74-0.96).
CONCLUSIONS: Infants who suffer major adverse event due to over-shunting experience considerably poorer outcomes than those who experience events due to shunt block. A mainly hypoxic event with maintenance of systemic perfusion (as often seen in a blocked shunt) is less likely to result in poorer outcomes than those after a hypoxic-ischemic event (commonly seen in over-shunting).
DESIGN: This is a secondary analysis of a multicenter, retrospective, cohort study. Data on epidemiology, ventilation, therapies, and outcomes were collected and analyzed. Patients were classified into two mutually exclusive groups (extrapulmonary pediatric acute respiratory distress syndrome and pulmonary pediatric acute respiratory distress syndrome) based on etiologies. Primary outcome was PICU mortality. Cox proportional hazard regression was used to identify risk factors for mortality.
SETTING: Ten multidisciplinary PICUs in Asia.
PATIENTS: Mechanically ventilated children meeting the Pediatric Acute Lung Injury Consensus Conference criteria for pediatric acute respiratory distress syndrome between 2009 and 2015.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Forty-one of 307 patients (13.4%) and 266 of 307 patients (86.6%) were classified into extrapulmonary pediatric acute respiratory distress syndrome and pulmonary pediatric acute respiratory distress syndrome groups, respectively. The most common causes for extrapulmonary pediatric acute respiratory distress syndrome and pulmonary pediatric acute respiratory distress syndrome were sepsis (82.9%) and pneumonia (91.7%), respectively. Children with extrapulmonary pediatric acute respiratory distress syndrome were older, had higher admission severity scores, and had a greater proportion of organ dysfunction compared with pulmonary pediatric acute respiratory distress syndrome group. Patients in the extrapulmonary pediatric acute respiratory distress syndrome group had higher mortality (48.8% vs 24.8%; p = 0.002) and reduced ventilator-free days (median 2.0 d [interquartile range 0.0-18.0 d] vs 19.0 d [0.5-24.0 d]; p = 0.001) compared with the pulmonary pediatric acute respiratory distress syndrome group. After adjusting for site, severity of illness, comorbidities, multiple organ dysfunction, and severity of acute respiratory distress syndrome, extrapulmonary pediatric acute respiratory distress syndrome etiology was not associated with mortality (adjusted hazard ratio, 1.56 [95% CI, 0.90-2.71]).
CONCLUSIONS: Patients with extrapulmonary pediatric acute respiratory distress syndrome were sicker and had poorer clinical outcomes. However, after adjusting for confounders, it was not an independent risk factor for mortality.
DESIGN: Prospective observational study.
SETTING: PICU in a tertiary care pediatric hospital.
PATIENTS: All English-literate parents whose child was admitted to our PICU between February 2014 and February 2015 were eligible after informed consent was obtained. Parents included in this study in previous admission(s) were excluded.
INTERVENTION: Nil.
MEASUREMENTS AND MAIN RESULTS: We adapted Empowerment of Parent in the Intensive Care Questionnaire, a validated questionnaire survey specific for measuring parental satisfaction in PICUs. This adapted survey consisted of 31 questions (based on a scale of 1-6) examining five domains as follows: information giving, care and cure, parental participation, organization, and professional attitude. Reliability of Empowerment of Parent in the Intensive Care Questionnaire in our population was analyzed using Cronbach's alpha. We used ordinal logistic regression, controlling for socioeconomic status and educational level, to examine differences in parental perceptions of various ethnicities. We obtained a total of 206 responses (36.5%) from 543 admissions. There were 116 (56%) emergency and 90 (44%) elective admissions. The proportion of respondents were Chinese (126 [61%]), Malay (32 [16%]), Indian (23 [11%]), and "Others" (25 [12%]). Cronbach's alpha for domains of information giving (α = 0.80), care and cure (α = 0.93), parental participation (α = 0.84), organization (α = 0.79), and professional attitude (α = 0.88) were good. In all five domains, our median PICU scores were 6 (interquartile range, 5-6). Compared to other ethnic groups, Malay parents did perceive that domains of "care and cure," "parental participation," and "professional attitude" were less satisfactory.
CONCLUSIONS: Significant differences were found in satisfaction ratings between parents of different ethnicities. Further studies are needed to explore and determine reasons for these differences.
DESIGN: We conducted a modified three-round eDelphi survey with pediatric critical care nurses in Asia. The eDelphi technique has been extensively used within health research to achieve a common viewpoint from experts using questionnaires to gather research priorities. In round 1, participants were asked to list three to five research topics that they deemed important. These topics were thematically analyzed and categorized into a questionnaire. Participants rated the research topics in round 2 on a 6-point scale (1 = not important to 6 = extremely important). In round 3, the same questionnaire was used with addition of the calculated mean scores from round 2 for each topic. Research topics ranked among the top 10 were considered extremely important.
SETTINGS: Twenty-two PICUs in eight Asian countries.
SUBJECTS: Clinical nurses, managers, educators, and researchers.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: In round 1, 146 PICU nurses across eight countries provided 520 research topics. Topics from round 1 were categorized into seven domains with 52 research topics. Prioritized research topics included early recognition of patient deterioration (mean 5.58 ± 0.61), prevention of healthcare-associated infections (mean 5.47 ± 0.70), and interventions to reduce compassion fatigue (mean 5.45 ± 0.80). The top three research domains were end-of-life care (mean 5.34 ± 0.68), professionalism (mean 5.34 ± 0.69), and management of pain, sedation, and delirium (5.32 ± 0.72).
CONCLUSIONS: This first PICU nursing research prioritization exercise within Asia identified key nursing research themes that should be prioritized and provide a framework for future collaborative studies.
DESIGN, SETTING, AND PATIENTS: Retrospective cohort study of children with dengue 1 month to 16 years old with admission ferritin greater than or equal to 500 ng/mL requiring PICU admission. Demographics, clinical, and laboratory parameters, presence of the 2009 WHO sd criteria and outcomes were analyzed. Immunomodulatory therapy was used when there was persistent hyperinflammation beyond the critical phase of plasma leakage.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Fifty-five patients were admitted in the critical phase of dengue with median (interquartile range) ferritin levels of 8,105 ng/mL (2,350-15,765 ng/mL). Patients with at least one WHO sd category had higher ferritin levels compared to those without any sd criteria, with the highest levels in eight patients with all three sd categories. In our cohort of 55, 52 patients (94%) recovered with standard supportive therapy. Recovery was associated with decreased ferritin levels that occurred in parallel with improved circulation and platelet counts; this included 22 of 24 patients with admission ferritin levels greater than or equal to 10,000 ng/mL and two with ferritin greater than 1,00,000 ng/mL. Immunomodulation was used in three patients with unremitting fever, persistent hyperferritinemia, and progressive multiple organ dysfunction beyond the critical phase, of whom two died.
CONCLUSIONS: Hyperferritinemia in the critical phase of sd is associated with the number of 2009 WHO sd criteria present. Our data also indicate that many patients with sd recover well with supportive care.
DESIGN: Secondary analysis of a cross-sectional point prevalence study.
SETTING: A total of 128 PICUs in 26 countries.
PATIENTS: Less than 18 years with severe sepsis on 5 separate days (2013-2014).
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Patients were categorized as having either no neurologic dysfunction or neurologic dysfunction (i.e., present at or after sepsis recognition), which was defined as Glasgow Coma Scale score less than 5 and/or fixed dilated pupils. Our primary outcome was death or new moderate disability (i.e., Pediatric Overall [or Cerebral] Performance Category score ≥3 and change ≥1 from baseline) at hospital discharge, and 87 of 567 severe sepsis patients (15%) had neurologic dysfunction within 7 days of sepsis recognition (61 at sepsis recognition and 26 after sepsis recognition). Primary site of infection varied based on presence of neurologic dysfunction. Death or new moderate disability occurred in 161 of 480 (34%) without neurologic dysfunction, 45 of 61 (74%) with neurologic dysfunction at sepsis recognition, and 21 of 26 (81%) with neurologic dysfunction after sepsis recognition (p < 0.001 across all groups). On multivariable analysis, in comparison with those without neurologic dysfunction, neurologic dysfunction whether at sepsis recognition or after was associated with increased odds of death or new moderate disability (adjusted odds ratio, 4.9 [95% CI, 2.3-10.1] and 10.7 [95% CI, 3.8-30.5], respectively). We failed to identify a difference between these adjusted odds ratios of death or new moderate disability that would indicate a differential risk of outcome based on timing of neurologic dysfunction (p = 0.20).
CONCLUSIONS: In this severe sepsis international cohort, the presence of neurologic dysfunction during sepsis is associated with worse outcomes at hospital discharge. The impact of early versus late onset of neurologic dysfunction in sepsis on outcome remains unknown, and further work is needed to better understand timing of neurologic dysfunction onset in pediatric sepsis.
DESIGN: A retrospective study of the Pediatric Acute and Critical Care Medicine Asian Network moderate to severe traumatic brain injury dataset collected between 2014 and 2017.
SETTING: Patients were from the participating PICUs of Pediatric Acute and Critical Care Medicine Asian Network.
PATIENTS: We included children less than 16 years old with a Glasgow Coma Scale less than or equal to 13.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: We obtained data on patient demographics, injury circumstances, and PICU management. We performed a multivariate logistic regression predicting for mortality and poor functional outcomes. We analyzed 380 children with moderate to severe traumatic brain injury. Most injuries were a result of road traffic injuries (174 [45.8%]) and falls (160 [42.1%]). There were important differences in temperature control, use of antiepileptic drugs, and hyperosmolar agents between the sites. Fifty-six children died (14.7%), and 104 of 324 survivors (32.1%) had poor functional outcomes. Poor functional outcomes were associated with non-high-income sites (adjusted odds ratio, 1.90; 95% CI, 1.11-3.29), Glasgow Coma Scale less than 8 (adjusted odds ratio, 4.24; 95% CI, 2.44-7.63), involvement in a road traffic collision (adjusted odds ratio, 1.83; 95% CI, 1.04-3.26), and presence of child abuse (adjusted odds ratio, 2.75; 95% CI, 1.01-7.46).
CONCLUSIONS: Poor functional outcomes are prevalent after pediatric traumatic brain injury in Asia. There is an urgent need for further research in these high-risk groups.
