Retrospective evaluation of a vancomycin dosing bundle in paediatric intensive care.

Background: Unplanned extubations (UE) are directly associated with morbidity, mortality, and increased health care costs amongst critically-ill children. Multi-center implementation of the Solutions for Patient Safety Network prevention bundle has been successful, but UE rates remain a common cause of preventable health care harm. Methods: This was a longitudinal (2020-2025), multi-intervention quality improvement (QI) project in a single quaternary care pediatric intensive care unit (PICU) driven largely by a new QI respiratory therapist. Interventions built upon the initial implementation of the UE prevention bundle. The smart aim of this project was to sustainably decrease UE/100 invasive ventilationdays in the PICU at Children's of Alabama by 50% through multiple Plan-Study-Do-Act (PDSA) cycles. Results: The baseline event rate was 0.58 UE/100 invasive ventilation days. Criteria for a center line shift to 0.16 UE/100 invasive mechanical ventilation days (72.5% decrease) were met in the first quarter of 2023 following four PDSA cycles and sustained through the end of the project. There was no change in invasive ventilation days/patient/quarter, but the percentage of PICU patients exposed to invasive ventilation by quarter starting dropped from 42% to 33% beginning in the first quarter of 2021. There were no center line shifts in post-UE outcomes over the project period including re-intubation within 1 h, re-intubation with cardiopulmonary resuscitation, or no re-intubation. Conclusions: Through multiple interventions, UE/100 invasive ventilation days decreased by 72.5% and has been sustained from the first quarter of 2023 through the second quarter of 2025 without impacting balancing measures such as invasive ventilation duration. These results support the importance of building upon the Solutions for Patient Safety Network UE prevention bundle and havinga dedicated champion to drive improvement and sustainability.

Objective To summarize the clinical features, treatment status and prognosis of severe community-acquired pneumonia (CAP) caused by adenovirus in a single pediatric intensive care unit (PICU), and to explore the appropriate diagnosis and treatment strategies. Methods From August 2016 to January 2019, the clinical data of children with adenovirus pneumonia, including symptoms, organ function, laboratory features, rescue measures and results were analyzed retrospectively. Results A total of 531 cases with severe CAP were admitted in PICU, Shanghai Children′s Hospital, Shanghai Jiaotong University.Among them, 32 cases with adenovirus pneumonia accounted for 6.03%.The high incidence age was from 3 months to 2 years old (68.8%), and the average age was 18(12, 37) months.High fever, respiratory distress and mental infirmity were the main symptoms.In acute stage, the pulmonary asymmetrical exudation lesion, partial exudation fusion and interstitial emphysema were observed by chest X rays.The main complications of extrapulmonary organ were cardiovascular disorder (63.1%), gastrointestinal disorder (50%), liver dysfunction (46.9%), coagulation dysfunction (31.3%) and nervous system dysfunction (26.1%). Respiratory support included high flow nasal oxygen therapy in 2 cases, mechanical ventilation in 30 cases, prone position ventilation in 12 cases, and continuous renal replacement therapy (CRRT) in 9 cases, extracorporeal membrane oxygenation (ECMO) therapy in 6 cases.There were 5 cases of death, and the hospital mortality was 15.6%.There were 4 cases survived by ECMO, and the discharge rate was 66.7%. Conclusion Adenovirus infection remains an important cause of CAP in PICU, and the mortality is high.Prone position ventilation, CRRT and ECMO may improve the survival rate of severe adenovirus pneumonia in children.

Acute kidney injury (AKI) occurs commonly in critically ill children and has been associated with increased mortality of up to 50 %. The Kidney Disease: Improving Global Outcomes (KDIGO) AKI working group has proposed a standardized definition of AKI. Utilizing routinely available clinical data, we evaluated the KDIGO AKI criteria and the relationship of AKI with relevant outcomes in a single center tertiary pediatric intensive care (PICU) and cardiac intensive care unit (CICU) population. The University of Michigan Pediatric Critical Care Database was probed for all discharges from the pediatric intensive care and cardiac intensive care units between July 2011 and October 2013 (N = 4,645). The KDIGO serum creatinine (SCr)-based criteria staged AKI with the modification that a minimum SCr of greater than 0.5 mg/dL was required to be classified as AKI. Exclusion: end-stage renal disease, new renal transplant, missing PRISM III data, or no measured Cr during intensive care unit (ICU) admission (N = 1,636). AKI occurred in 737 (24.5 %, stage 1 = 193, stage 2 = 189, and stage 3 = 355) of 3,009 discharges (PICU N = 1,870, CICU N = 1,139) that included 2,415 patients. In multivariate analysis AKI was associated with increased ICU length of stay (LOS) in hours (stage I β = 42.2, p = 0.024, II β = 74.1, p = 0.003, III β = 215.8, p < 0.001). Multivariate analysis showed that AKI was associated with increased odds of ICU mortality (OR 3.4, 95 % CI 2.0-6.0) and increased length of mechanical ventilation among those requiring mechanical ventilation (β = 2.3 days, p < 0.001). Using the KDIGO criteria to define AKI, we observed a high prevalence of AKI among critically ill children. Worsening stages of AKI were associated with increased ICU LOS, and AKI was independently associated with prolonged mechanical ventilation and increased mortality. The KDIGO criteria describe clinically relevant AKI in a broad pediatric critical care population.

We compared acute patients admitted to a single paediatric intensive care unit (PICU) following an emergency transfer by a specialist paediatric transport team and by other routes. This was a retrospective descriptive register-based study of consecutive admissions to a tertiary PICU in Sweden from 1 January 2008 to 31 December 2013. We compared the general characteristics of the cohorts, together with predicted death rates (PDR), PICU mortality, 30-day mortality, PICU length of stay (PICU LOS) and resource use. Of the 3665 nonelective admissions, 221 patients received emergency transport from referring hospitals to the PICU by the specialist paediatric transport team. Their median age was lower (146 versus 482 days), PDR was higher (5.58% versus 1.39%), PICU LOS was longer (4.24 days versus 1.06 days), and they received more PICU-specific therapies. The standardised mortality ratio did not differ between the cohorts, and the PICU mortality was lower than predicted in both groups. The transport distance and mode of transport did not influence survival. Children admitted to the PICU following emergency transfers by the specialist paediatric transport team were younger, sicker, received more PICU-specific therapies and had longer PICU LOS than other acutely admitted critically ill patients. This indicates that these transfers were appropriate.

Vancomycin is a glycopeptide antibiotic used for the treatment of severe gram-positive infections. Despite decades of clinical experience, optimized dosing for vancomycin in pediatric populations still warrants further investigation. Patients admitted to the pediatric intensive care unit (PICU) after cardiac surgery are often treated with vancomycin in case of (suspected) infection. However, vancomycin dosing in this population is often challenging due to fluctuations in volume status, (temporarily) compromised renal function or the use of diuretics or extracorporeal membrane oxygenation (ECMO). The main objective of this study was to describe vancomycin pharmacokinetics (PK) in pediatric cardiac surgery patients. Secondary objectives were to potentially optimize vancomycin dosing and to assess the suitability of the model to be used for model informed precision dosing (MIPD). A retrospective cohort study was performed with patients admitted to the PICU of the Leiden University Medical Center. Clinical data from post-cardiac surgery PICU patients receiving intravenous vancomycin between January 2020 and December 2023 were included in the analysis. Patients received vancomycin 10 mg/kg 4 times daily (qid), after which a trough concentration was generally sampled just before the fourth dose. Pharmacokinetic data were used to develop a population PK model by using a non-linear mixed effects modeling approach (NONMEM). In addition, potential covariates such as renal function, body weight (BW) and post-menstrual age were tested. The final model was used for vancomycin dose optimization using Monte Carlo simulations. In total, 193 pediatric post-cardiac surgery patients, contributing a total of 706 vancomycin blood samples were included. The 2-compartmental population PK model best described the data. Renal function and BW were identified as significant and clinically relevant covariates on vancomycin PK. Model parameters were: elimination clearance: 4.01 L/min at 70 kg; intercompartmental clearance: 0.425 L/min at 70 kg; central volume of distribution: 56.1 L/70 kg; and peripheral volume of distribution: 21.7 L/70 kg (fixed). Dose simulations suggested a non-linear dosing algorithm, with relatively lower per kg dose for increasing BW to be optimal for our population. Furthermore, the model was considered to be suitable for the (a posteriori) prediction of future vancomycin serum concentrations. We successfully developed a population PK model for vancomycin in post-cardiac surgery children. Vancomycin PK were shown to be significantly influenced by serum creatinine and BW. Furthermore, we suggest a new vancomycin dosing regimen based on allometric scaling. The developed PK model can be used for model informed precision dosing of vancomycin in pediatric post-cardiac surgery patients.

Healthcare can cause harm. The goal of this study is to evaluate the association between the occurrence of adverse events (AEs) and morbidity-mortality in critically ill children. A prospective cohort study was designed. All children admitted to the Pediatric Intensive Care Unit (PICU) between August 2016 and July 2017 were followed. An AE was considered any harm associated with a healthcare-related incident. AEs were identified in two steps: first, adverse clinical incidents (ACI) were recognized through direct observation and active surveillance by PICU physicians, and then the patient safety committee evaluated every ACI to define which would be considered an AE. The outcome was hospital morbidity-mortality. There were 467 ACI registered, 249 (53.31%) were considered AEs and the rate was 4.27/100 patient days. From the 842 children included, 142 (16.86%) suffered AEs, 39 (4.63%) experienced morbidity-mortality: 33 (3.92%) died, and 6 (0.71%) had morbidity. Multivariate analysis revealed that the occurrence of AEs was significantly associated with morbidity-mortality, OR 5.70 (CI95% 2.58-12.58, p = 0.001). This association was independent of age and severity of illness score.Conclusion: Experiencing AEs significantly increased the risk of morbidity-mortality in this cohort of PICU children.What is Known:• Many children suffer healthcare-associated harm during pediatric intensive care hospitalization.What is New:• This prospective cohort study shows that experiencing adverse events during pediatric intensive care hospitalization significantly increases the risk of morbidity and mortality independent of age and severity of illness at admission.

In Latvia, there is a single eight-bed paediatric intensive care unit (PICU) where all critically ill children are admitted. A recent retrospective audit of the outcomes of paediatric critical care in this unit revealed a high number of unplanned extubations and excess crude mortality. In 2017, our centre joined the UK and Ireland based Paediatric Intensive Care Audit Network (PICANet) as a pilot project to investigate the feasibility of developing a paediatric critical care registry in Latvia and in the Baltic states. Riga Stradins University Ethics Committee approved the study. Anonymized data on all patients admitted to our unit from 1 June, 2017 to 31 May 2018 were prospectively entered onto the PICANet database. A total of 774 PICU admissions were analysed; 45% of admissions were elective. The median age was 59 months (IQR: 14-149). The highest admission rate was on Wednesdays representing the flow of elective surgical patients. The median length of stay was 0.95 days (IQR: 0.79-1.98). Twenty-five percent required respiratory support. The expected number of deaths estimated using the Paediatric Index of Mortality 3 (PIM 3) 15.16; 15 patients (1.94%) died resulting in Standartized Mortality Ratio (SMR) of 0.99 (95% CI 0.57-1.60). The emergency readmission rate within 48 hours after PICU discharge was 0.9%. There were 1.8 unplanned extubations per 100 invasive ventilation days. Other paediatric intensive care audit networks reported similar adjusted mortality rates but lower rates of unplanned extubations. Thirty days after PICU discharge, 653 (84.36%) patients were alive and outside hospital, 98 (12.66%) were inpatients, six (0.78%) had died, two (0.26%) were lost to the follow-up. We observed a marked peak of infant emergency respiratory admissions in February. This project explored the possibility of prospective paediatric critical care audit in Latvia by joining an established international network. This allowed direct comparison of outcomes between the countries. Excess mortality was not observed during one-year data collection period, however a high rate of unplanned extubations was revealed. The results allowed a better planning of elective patient flow by spreading elective cases over the week to avoid "rush hours".

To describe the health care service provided in pediatric intensive care units in the city of São Paulo, by identifying and describing the units and analyzing their geographic distribution.A descriptive cross-sectional study was carried out during a two-year period (August 2000 to July 2002). Data were collected through questionnaires answered by medical directors of each pediatric and neonatal intensive care unit.São Paulo is served by 107 pediatric and neonatal intensive care units, of which 85 (79.4%) completed and returned the questionnaire. We found a very unequal distribution of units as there were more units in places with the least pediatric population. Regarding to pediatric intensive care units specialization, 7% were pediatric, 41.2% were neonatal and 51.7% were mixed (pediatric and neonatal). Regarding hospital funds, 15.3% were associated with philanthropic institutions, 37.6% were private and 47% were public. A total of 1,067 beds were identified, of which 969 were active. The ratio bed/patient aged 0-14 was 1/2,728, varying from 1/604 at health districts-I to 1/6,812 at health districts-III. The units reported an average of 11.7 beds (2 to 60). The neonatal intensive care unit had a median of 16.9 beds per unit and pediatric intensive care units a median of 8.5 beds/unit.In São Paulo, we found an uneven distribution of pediatric and neonatal intensive care units among the health districts. There was also an uneven distribution between public and private units, and neonatal and pediatric ones. The current report is the first step in the effort to improve the quality of medical assistance in pediatric and neonatal intensive care units in São Paulo.

A recent systematic review concluded that critically ill pediatric patients have higher odds of vancomycin-related nephrotoxicity [odds ratio (OR): 3.61, 95% CI: 1.21-10.74]. We aimed to assess the incidence and risk factors for vancomycin-associated nephrotoxicity in critically ill children without preexisting renal injury. A cohort of children admitted to a pediatric intensive care unit, from 2011 to 2016 treated with vancomycin without preexisting renal injury. The main diagnosis, therapeutic interventions and medications administered in this period were evaluated. Generalized estimating equation models were used to assess the association between clinical covariates and the dependent variable pediatric risk, injury, failure, loss, end-stage renal disease (pRIFLE). Hundred ten patients, representing 1177 vancomycin days, were analyzed. Vancomycin-associated nephrotoxicity was seen in 11.8%. In a multivariate model, higher vancomycin doses were not associated with poorer renal function (P = 0.08). Higher serum vancomycin levels were weakly associated with pRIFLE classification (OR: 1.05, 95% CI: 1.02-1.07). Furosemide or amphotericin B in addition to the vancomycin treatment was associated with impaired renal function (OR: 2.56, 95% CI: 1.38-4.8 and OR: 7.7 95% CI: 2.55-23, respectively). Vancomycin-associated nephrotoxicity in acute ill children without preexisting renal injury, measured with pRIFLE, is close to 11.8%. Furosemide and amphotericin B in addition to the vancomycin treatment are strong predictors of worse pRIFLE scores. The influence of acute kidney injury status at pediatric intensive care unit admission and the method used for renal function assessment might influence the incidence of vancomycin-associated nephrotoxicity and its associated risk factors.

ObjectiveTo identify the neonatal, pediatric and mixed (neonatal and pediatric) intensive care units in Brazil that use cuffed tracheal tubes in clinical practice and to describe the characteristics related to the use of protocols and monitoring.MethodsTo identify the intensive care units in Brazil, the Ministry of Health’s National Registry of Health Facilities was accessed, and information was collected on 693 registered intensive care units. This was an analytical cross-sectional survey conducted through electronic questionnaires sent to 298 neonatal, pediatric and mixed intensive care units in Brazil.ResultsThis study analyzed 146 questionnaires (49.3% from neonatal intensive care units, 35.6% from pediatric intensive care units and 15.1% from mixed pediatric intensive care units). Most of the participating units (78/146) used cuffed tracheal tubes, with a predominance of use in pediatric intensive care units (52/78). Most of the units that used cuffed tracheal tubes applied a cuff pressure monitoring protocol (45/78). The use of cuff monitoring protocols was observed in intensive care units with a physical therapy service exclusive to the unit (38/61) and in those with a physical therapist present 24 hours/day (25/45). The most frequent cause of extubation failure related to the use of cuffed tracheal tubes in pediatric intensive care units was upper airway obstruction.ConclusionIn this survey, the use of cuffed tracheal tubes and the application of a cuff pressure monitoring protocol was predominant in pediatric intensive care units. The use of a monitoring protocol was more common in intensive care units that had a physical therapist who was exclusive to the unit and was present 24 hours/day.

Objective: Identifying antibiotic use in pediatric and neonatal intensive care units with a point prevalence study in Adana, Turkey’s sixth largest city. Material and Methods: In this point prevalence study, demographic information and antibiotic treatment data were taken on the same day from patients in pediatric and neonatal intensive care units of 6 hospitals located in Adana’s city center. Results: Four pediatric intensive care units (two university, one research and training hospital, and one public hospital) and six neonatal intensive care units (two university, one research and training hospital, one public hospital, and two private hospital) were included in the study; 220 patients were at the intensive care units at the time of the study, 44 (20%) of the patients were in the pediatric intensive care units, and 176 (80%) of them were at the neonatal intensive care units. Also, 146 (66.4%) of the patients were using antibiotics. The frequency of antibiotic use was 72.7% in the pediatric intensive care units and 64.8% in neonatal intensive care units. There was a pediatric infectious disease physician at the university and research and training hospital. Antibiotic usage was lower (p=0.002) in clinics where pediatric infectious disease physician consultations could be done. Double antibiotic combination was applied most frequently. Mostly, ampicillin was preferred at neonatal intensive care units. Clarithromycin was used as a second choice because of seasonal lower respiratory tract infections. Vancomycin was the most preferred antibiotic in pediatric intensive care units, and meropenem and linezolid were the second and third choices. At both intensive care units, use of empiric antibiotic treatment was more frequent. Empiric treatment was applied in 22 (68.7%) patients in the pediatric intensive care units and 95 (83.3%) in neonatal intensive care units. Antibiotics were given to 14.3% of the patients in line with the resulting cultures. Conclusion: Intensive care units are services where antibiotics are used most frequently both in Turkey and in the world. In our opinion, protocols need to be established in clinics, national and international guides should be followed; and pediatric infectious disease physician consultations should be increased in order to reduce the frequency of antibiotic use, inappropriate indications, and inappropriate doses.

To estimate the prevalence of the most frequent infections related to device utilization and their antimicrobial sensitivity panel, and to investigate the overall incidence of device associated infection rates per 1000 device days, at the pediatric intensive care unit of the Jordan University of Science and Technology.This is a retrospective study from a single pediatric intensive care unit. Data were collected in relation to bloodstream infections associated with central venous catheters, pneumonia associated with ventilator endotracheal tubes, and urinary tract infections associated with Foley catheters, between January 2013 and December 2018, according to the center of disease control and prevention protocols.During the 5-year study, 3195 patients were admitted to the pediatric intensive care unit for a total of 16,487 days. Forty-six patients (1.4%) developed 55 infections, with a median incidence rate of 7.4, 3.7, and 0.7 per 1000 days for central line associated infections, ventilator associated pneumonia, and catheter associated infections, respectively. The commonest isolated microorganisms were gram-negative bacteria in 89.1% of cases, and fungi in 10.9% of cases. Among the resistant bacterial isolates, 59.2% were multidrug resistant, and 32.6% were extended spectrum beta lactamase producers Klebsiella pneumoniae and Eschericia coli. High infection rates were related to Acinetobacter baumannii and K pneumoniae, associated with high resistance to cephalosporins. Susceptibility was highest to tigecycline and imipenem at 42.9% and 32.7% respectively.Microbial isolates are commonly associated with healthcare device insertions in pediatric intensive care unit, invasive bacterial infections associated with critical morbidity and mortality. Further studies on device associated infections are recommended for regional profiling purposes.
