Dar A, Abram TB, Megged O. Impact of inadequate empirical antibiotic treatment on outcome of non-critically ill children with bacterial infections. BMC Pediatr 2024; 24:324. [PMID: 38734642 PMCID: PMC11088006 DOI: 10.1186/s12887-024-04793-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 04/26/2024] [Indexed: 05/13/2024] Open
Abstract
BACKGROUND The impact of inadequate empirical antibiotic treatment on patient outcomes and hospitalization duration for non-life-threatening infections in children remains poorly understood. We aimed to assess the effects of inadequate empirical antibiotic treatment on these factors in pediatric patients. METHODS The medical records of children admitted for infectious diseases with bacteria isolated from sterile sites between 2018 and 2020 were retrospectively reviewed. Patients who received adequate empirical treatment were compared with those who received inadequate treatment in terms of demographic, clinical, and laboratory variables. RESULTS Forty-eight patients who received inadequate empirical antimicrobial treatment were compared to 143 patients who received adequate empirical treatment. Inadequate empirical antimicrobial treatment did not significantly affect the length of hospital stay or the incidence of complications in non-critically ill children with bacterial infections. Younger age and underlying renal abnormalities were identified as risk factors for inadequate antimicrobial treatment, while associated bacteremia was more common in the adequate antimicrobial treatment group. CONCLUSIONS inadequate antibiotic treatment did not affect the outcomes of non-critically ill children with bacterial infectious diseases. Therefore, routine empirical broad-spectrum treatment may not be necessary for these cases, as it can lead to additional costs and contribute to antibiotic resistance. Larger prospective studies are needed to confirm these findings.

Abstract
OBJECTIVES Respiratory syncytial virus (RSV) in pediatric patients has been associated with low risk of concomitant bacterial infection. However, in children with severe disease, it occurs in 22% to 50% of patients. As viral testing becomes routine, bacterial codetections are increasingly identified in patients with non-RSV viruses. We hypothesized, among patients intubated for respiratory failure secondary to suspected infection, there are similar rates of codetection between RSV and non-RSV viral detections. METHODS This retrospective chart review, conducted over a 5-year period, included all patients younger than 2 years who required intubation secondary to respiratory failure from an infectious etiology in a single pediatric emergency department. Patients intubated for noninfectious causes were excluded. RESULTS We reviewed 274 patients, of which 181 had positive viral testing. Of these, 48% were RSV-positive and 52% were positive for viruses other than RSV. Codetection of bacteria was found in 76% (n = 65; 95% confidence interval [CI], 66%, 84%) of RSV-positive patients and 66% (n = 63, 95% CI: 57%, 76%) of patients positive with non-RSV viruses. Among patients with negative viral testing, 33% had bacterial growth on lower respiratory culture. Male sex was the only patient-related factor associated with increased odds of codetection (odds ratio [OR], 2.2; 95% CI, 1.08-4.38). The odds of codetection between RSV-positive patients and non-RSV viruses were not significantly different (OR, 1.3; 95% CI, 0.62-2.71). CONCLUSIONS Bacterial codetection is common and not associated with anticipated patient-related factors or with a specific virus. These results suggest consideration of empiric antibiotics in infants with respiratory illness requiring intubation.

The Pharmacokinetics of Beta-Lactam Antibiotics Using Scavenged Samples in Pediatric Intensive Care Patients: The EXPAT Kids Study Protocol. Front Pharmacol 2021; 12:750080. [PMID: 34955824 PMCID: PMC8703159 DOI: 10.3389/fphar.2021.750080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Accepted: 11/08/2021] [Indexed: 11/26/2022] Open
Abstract
Background: Emerging evidence supports the importance of optimized antibiotic exposure in pediatric intensive care unit (PICU) patients. Traditional antibiotic dosing is not designed for PICU patients, as the extreme pharmacokinetic (PK) behavior of drugs threatens the achievement of optimal antibiotic treatment outcomes. Scavenged sampling is a sampling strategy which may have positive implications for routine TDM and PK research, as well as monitoring other biomarkers. EXPAT Kids study was designed to analyze whether current empiric dosing regimens of frequently used beta-lactam antibiotics achieve defined therapeutic target concentrations in PICU patients. Methods: A mono-centre, exploratory pharmacokinetic and pharmacodynamic study was designed to assess target attainment of beta-lactam antibiotics. One hundred forty patients will be included within 24 months after start of inclusion. At various time points serum concentration of the study antibiotic (cefotaxime, ceftazidime, ceftriaxone, cefuroxime, flucloxacillin, and meropenem) are determined. In parallel with these sampling moments, residual material is collected to validate the use of blood of scavenged heparinized astrup syringes for the quantification of antibiotic exposure. The primary outcome is the time that the free (unbound) concentration of the study antibiotic remains above one to four the minimal inhibitory concentration during a dosing interval (100%ƒT > MIC and 100%ƒT>4xMIC). Other included outcomes are disease severity, safety, length of stay, and inflammatory biomarkers. Discussion: Potentially, scavenged sampling may enrich the EXPAT Kids dataset, and reduce additional blood sampling and workload for clinical personnel. The findings from the EXPAT Kids study will lead to new insights in the PK parameters of beta-lactams and consecutive effects on target attainment and clinical outcomes. Is there a need for more precision in dosing? Netherlands Trial Register Number: Trial NL9326.

Thompson RZ, Sargel CL, Moore-Clingenpeel M, Karsies TJ. Creation of a Combination Antibiogram for Pseudomonas aeruginosa in a Pediatric Intensive Care Unit. J Pediatr Pharmacol Ther 2021; 26:828-833. [PMID: 34790073 DOI: 10.5863/1551-6776-26.8.828] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Accepted: 04/26/2021] [Indexed: 11/11/2022]
Abstract
OBJECTIVE This study describes the creation of a combination antibiogram directed toward Pseudomonas aeruginosa to determine the most appropriate empiric antimicrobial regimen(s). METHODS P aeruginosa isolates were collected from all sites between January 2013 and December 2017 for patients admitted to the PICU. Patients with cystic fibrosis and isolates from the same site and susceptibility pattern obtained within 30 days were excluded. β-Lactam susceptibilities were determined and compared with the addition of an aminoglycoside or fluroquinolone and summarized in a combination antibiogram. RESULTS One hundred ninety-nine P aeruginosa isolates were included for analysis. The addition of a second agent to piperacillin-tazobactam was shown to have the most significant improvement among the β-lactams, with 70% susceptibility as monotherapy and increases to above 90% with the addition of an aminoglycoside or fluroquinolone. The addition of an aminoglycoside or fluroquinolone to cefepime and meropenem increased coverage to above 95%. The addition of a second agent was likely to increase susceptibility of a monotherapy backbone; however, as the susceptibility of the first-line agent decreased, the susceptibility of the second agent needed to be higher to achieve a 95% coverage threshold. CONCLUSIONS Our results support use of a second agent to significantly improve the likelihood of appropriate empiric coverage of P aeruginosa. Use of a combination antibiogram may be more beneficial than a simple antibiogram for units with increasing resistance rates, or for coverage of specific resistant organisms.

Delayed Administration of Antibiotics Beyond the First Hour of Recognition Is Associated with Increased Mortality Rates in Children with Sepsis/Severe Sepsis and Septic Shock. J Pediatr 2021; 233:183-190.e3. [PMID: 33359300 DOI: 10.1016/j.jpeds.2020.12.035] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 11/26/2020] [Accepted: 12/15/2020] [Indexed: 12/30/2022]
Abstract
OBJECTIVE To compare the risk of mortality and other clinical outcomes in children with sepsis, severe sepsis, or septic shock who received antibiotics within the first hour of recognition (early antibiotics group) with those who received antibiotics after the first hour (delayed antibiotics group). STUDY DESIGN In this prospective cohort study, we enrolled children <17 years of age presenting to the pediatric emergency and diagnosed with sepsis or septic shock without prior antibiotic therapy. Primary outcome was mortality and the secondary outcomes were day 1 Pediatric Logistic Organ Dysfunction score, ventilator-free days, and hospital-free days. These outcomes were compared between the early and the delayed antibiotic groups. The reference point for defining early and delayed antibiotic groups was time 0, which was measured from the time the patient was diagnosed to have sepsis, severe sepsis, or septic shock to the time of administration of the first dose of antibiotics. RESULTS About three-fourths (77%) of the 441 children enrolled had septic shock. A total of 241 (55%) and 200 (45%) children were in the delayed and early antibiotic groups, respectively. Children in the delayed group had significantly higher odds of mortality than those in the early group (29% vs 20%; aOR 1.83; 95% CI, 1.14-2.92; P = .01). The time to shock reversal was significantly shorter, and the ventilator-free days and hospital-free days were significantly greater, in the early antibiotic group. There was no difference between the groups with regard to any of the other clinical outcomes. CONCLUSIONS Delayed administration of antibiotics beyond 1 hour of recognition was associated with higher mortality rates in children with sepsis, severe sepsis, and septic shock. Antibiotics should be administered within the first hour, along with other resuscitative measures, in these children.

Abstract
Antibiotics are one of the most prescribed drug classes in the pediatric intensive care unit, yet the incidence of inappropriate antibiotic prescribing remains high in critically ill children. Optimizing the use of antibiotics in this population is imperative to guarantee adequate treatment, avoid toxicity and the occurrence of antibiotic resistance, both on a patient level and on a population level. Antibiotic stewardship encompasses all initiatives to promote responsible antibiotic usage and the PICU represents a major target environment for antibiotic stewardship programs. This narrative review provides a summary of the available knowledge on the optimal selection, duration, dosage, and route of administration of antibiotic treatment in critically ill children. Overall, more scientific evidence on how to optimize antibiotic treatment is warranted in this population. We also give our personal expert opinion on research priorities.

Abstract
OBJECTIVE To determine if time to antibiotic administration is associated with mortality and in-hospital outcomes in a neonatal intensive care unit (NICU) population. STUDY DESIGN We conducted a prospective evaluation of infants with suspected sepsis between September 2014 and February 2018; sepsis was defined as clinical concern prompting blood culture collection and antibiotic administration. Time to antibiotic administration was calculated from time of sepsis identification, defined as the order time of either blood culture or an antibiotic, to time of first antibiotic administration. We used linear models with generalized estimating equations to determine the association between time to antibiotic administration and mortality, ventilator-free and inotrope-free days, and NICU length of stay in patients with culture-proven sepsis. RESULTS Among 1946 sepsis evaluations, we identified 128 episodes of culture-proven sepsis in 113 infants. Among them, prolonged time to antibiotic administration was associated with significantly increased risk of mortality at 14 days (OR, 1.47; 95% CI, 1.15-1.87) and 30 days (OR, 1.47; 95% CI, 1.11-1.94) as well as fewer inotrope-free days (incidence rate ratio, 0.91; 95% CI, 0.84-0.98). No significant associations with ventilator-free days or NICU length of stay were demonstrated. CONCLUSIONS Among infants with sepsis, delayed time to antibiotic administration was an independent risk factor for death and prolonged cardiovascular dysfunction. Further study is needed to define optimal timing of antimicrobial administration in high-risk NICU populations.

Abstract
OBJECTIVES To define and measure complications across a broad set of acute pediatric conditions in emergency departments using administrative data, and to assess the validity of these definitions by comparing resource utilization between children with and without complications. STUDY DESIGN Using local consensus, we predefined complications for 16 acute conditions including appendicitis, diabetic ketoacidosis, ovarian torsion, stroke, testicular torsion, and 11 others. We studied patients under age 18 years using 3 data years from the Healthcare Cost and Utilization Project Statewide Databases of Maryland and New York. We measured complications by condition. Resource utilization was compared between patients with and without complications, including hospital length of stay, and charges. RESULTS We analyzed 27 087 emergency department visits for a serious condition. The most common was appendicitis (n = 16 794), with 24.3% of cases complicated by 1 or more of perforation (24.1%), abscess drainage (2.8%), bowel resection (0.3%), or sepsis (0.9%). Sepsis had the highest mortality (5.0%). Children with complications had higher resource utilization: condition-specific length of stay was longer when complications were present, except ovarian and testicular torsion. Hospital charges were higher among children with complications (P < .05) for 15 of 16 conditions, with a difference in medians from $3108 (testicular torsion) to $13 7694 (stroke). CONCLUSIONS Clinically meaningful complications were measurable and were associated with increased resource utilization. Complication rates determined using administrative data may be used to compare outcomes and improve healthcare delivery for children.

Abstract
Supplemental Digital Content is available in the text. Introduction: Children with severe infection have improved outcomes when they received antibiotics promptly. Positive cultures help guide physicians in antibiotic selection. In 2011, 30% of children intubated in the emergency department received antibiotics and had respiratory culture collected within 60 minutes of intubation. Knowing the risk of delaying appropriate antibiotics, we charted a quality improvement team to improve compliance with 80% of intubated patients receiving both. Methods: The team evaluated all children intubated with concern for infection in the emergency department. Using a multidisciplinary team and employing quality improvement methods, we implemented multiple plan-do-study-act cycles to improve time to antibiotics and respiratory cultures. The team continued to implement successful interventions and restarted interventions directly affecting improvement. Results: While multiple interventions had small effects on the baseline of 30% compliance, 2 interventions appeared more influential than others. Workflow changes and audit-and-feedback created the largest, persistent positive changes. The importance of audit-and-feedback became very obvious when the project entered sustain mode. An abrupt decrease in compliance occurred when audit-and-feedback stopped. Complete recovery in compliance to greater than 80% occurred with the resumption of the audit-and-feedback intervention. Conclusions: Workflow changes and audit-and-feedback interventions resulted in large improvements. Loss of compliance with cessation of the audit-and-feedback and resumption demonstrated the importance of this intervention. Recovery to >80% compliance with the renewal of the audit-and-feedback program indicates its strength as a positive intervention.

Abstract
Community-acquired pneumonia in children is associated with significant morbidity and mortality; however, data are limited in predicting which children will have negative outcomes, including clinical deterioration, severe disease, or development of complications. The Pediatric Infectious Diseases Society/Infectious Diseases Society of America (PIDS/IDSA) pediatric pneumonia guideline includes criteria that were modified from adult criteria and define pneumonia severity to assist with resource allocation and site-of-care decision-making. However, the PIDS/IDSA criteria have not been formally developed or validated in children. Definitions for mild, moderate, and severe pneumonia also vary across the literature, further complicating the development of standardized severity criteria. This systematic review summarizes (1) the current state of the evidence for defining and predicting pneumonia severity in children as well as (2) emerging evidence focused on risk stratification of children with pneumonia.

Abstract
Background Risk-based guidelines aid empiric antibiotic selection for critically ill adults with suspected infection with Gram-negative bacilli with high potential for antibiotic resistance (termed high-risk GNRs). Neither evidence-based guidelines for empiric antibiotic selection nor validated risk factors predicting high-risk GNR growth exist for critically ill children. We developed and validated a model for predicting high-risk GNR growth in critically ill children with suspected infection. Methods This is a retrospective cohort study involving 2 pediatric cohorts admitted to a pediatric intensive care unit (ICU) with suspected infection. We developed a risk model predicting growth of high-risk GNRs using multivariable regression analysis in 1 cohort and validated it in a separate cohort. Results In our derivation cohort (556 infectious episodes involving 489 patients), we identified the following independent predictors of high-risk GNR growth: hospitalization >48 hours before suspected infection, hospitalization within the past 4 weeks, recent systemic antibiotics, chronic lung disease, residence in a chronic care facility, and prior high-risk GNR growth. The model sensitivity was 96%, the specificity was 48%, performance using the Brier score was good, and the area under the receiver operator characteristic curve (AUROC) was 0.722, indicating good model performance. In our validation cohort (525 episodes in 447 patients), model performance was similar (AUROC, 0.733), indicating stable model performance. Conclusions Our model predicting high-risk GNR growth in critically ill children demonstrates the high sensitivity needed for ICU antibiotic decisions, good overall predictive capability, and stable performance in 2 separate cohorts. This model could be used to develop risk-based empiric antibiotic guidelines for the pediatric ICU.

Abstract
Aztreonam, a broad-spectrum monobactam, is typically reserved for multidrug resistant (MDR) infections. Pharmacokinetic (PK) data to guide dosing in children, however, are limited to healthy volunteers or nonintensive care unit (ICU) patients. Impaired antibiotic delivery into tissue remains a major concern and may explain the high morbidity and mortality associated with MDR infections. Therefore, evaluating the PK changes in pediatric ICU patients is necessary to elucidate the most appropriate antimicrobial regimen. We describe the PK of prolonged infusion aztreonam in a patient with MDR Pseudomonas aeruginosa empyema. The 16-year-old tetraplegic male with a cervical spinal cord injury, chronic respiratory failure, and tracheostomy was admitted with a 2-day history of fever and hypoxemia. Chest x-ray revealed a left lower lobe infiltrate. On hospital day 2, computed tomography scan noted a massive collapse of the left lung with bronchiectasis and hepatization with a pneumatocele. He underwent bronchoscopy on days 2, 6, and 10 and the cultures subsequently grew P aeruginosa only sensitive to aztreonam (minimum inhibitory concentration [MIC] of 2-6 mg/L). A regimen of aztreonam 2 grams intravenously (IV) every 6 hours (each dose infused over 4 hours) and polymyxin B 1,000,000 units IV every 12 hours (each dose infused over 30 minutes) was initiated on day 3. On day 8, the aztreonam serum plateau concentration was 71 mg/L. Repeat respiratory and bronchoscopy cultures from days 19 to 37 remained negative. Aztreonam clearance was 2.3 mL/kg/min, which was significantly increased when compared with the 1.3 mL/kg/min suggested in the prescribing information based on adult data. A prolonged infusion of 2 grams of aztreonam every 6 hours (each dose infused over 4 hours) successfully attained 100% of the target serum and lung concentrations above the MIC for at least 40% of the dosing interval, and was associated with successful treatment of MDR P aeruginosa empyema.

Development of indicators for assessing rational drug use to treat community-acquired pneumonia in children in hospitals and clinics: A modified Delphi study. Medicine (Baltimore) 2017; 96:e9308. [PMID: 29390500 PMCID: PMC5758202 DOI: 10.1097/md.0000000000009308] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2017] [Revised: 11/22/2017] [Accepted: 11/27/2017] [Indexed: 11/26/2022] Open
Abstract
Community-acquired pneumonia (CAP) is a common infectious disease in children. Rational drug use (RDU) is an important approach to reducing the disease burden and mortality rate of CAP in children. There are no monitoring indicators for assessing RDU in children. This study aimed to develop a set of indicators to assess RDU to treat CAP in children in hospitals and clinics using a modified Delphi method.Initial indicators were generated based on a systematic review of guidelines and studies investigating CAP in children. A 3-round modified Delphi process in the form of an email survey combined with round-table discussion was then carried out, and an analytic hierarchy process (AHP) was applied to determine the weight of each indicator.A total of 24 and 8 experts were invited to participate in the email survey and round-table discussion, respectively. A consensus was reached after 3 rounds of the Delphi survey. Three first-rank indicators and 23 second-rank indicators were developed, and each indicator was weighted. The first-rank indicators comprised drug choice (45.5%), drug usage and dosage (36.4%), and the duration of drug therapy (18.2%); the second-rank indicators were indicators related to antibiotics (63.6%), antiviral agents (18.2%), traditional Chinese medicines (4.5%), and adjuvant drugs (13.6%). The weight value of drug selection was the highest, followed by the values of drug usage and dosage and the duration of drug therapy.The developed indicator set constitutes the first set intended to assess RDU to treat CAP in children in hospitals (including community hospitals) and clinics. The indicators were based on drug selection, drug usage and dosage and duration of drug therapy, which are associated with most therapeutic drugs for CAP in children. Monitoring these indicators will guide people towards the promotion of RDU in the absence of drug monitoring indicators for CAP. Furthermore, the indicator set constitutes a methodological reference for the development of other indicator sets.

Abstract
OBJECTIVE This study aims to describe the population pharmacokinetics and pharmacodynamic target attainment of meropenem in critically ill children. METHODS The study involved a retrospective medical record review from a 189-bed, freestanding children's tertiary care teaching hospital of patients ages 1 to 9 years who received meropenem with concurrent therapeutic drug monitoring. RESULTS There were 9 patients ages 1 to 9 years (mean age, 3.1 ± 2.9 years) with a mean weight of 17.1 ± 11.9 kg who met the inclusion/exclusion criteria and were included in the pharmacokinetic analysis. Meropenem concentrations were best described by a 2-compartment model with first-order elimination, with an R2 and bias of 0.91 and 13.2 mg/L, respectively, for the observed versus population predicted concentrations, and an R2, bias, and imprecision of 1, 0.0675, and 1 mg/L, respectively, for the observed versus individual predicted concentrations. The mean total body drug clearance for the population was 6.99 ± 2.5 mL/min/kg, and Vc was 0.57 ± 0.47 L/kg. The calculated population estimate for the total volume of distribution was 0.78 ± 0.73 L/kg. Standard 0.5-hour meropenem infusions did not provide for appropriate pharmacodynamic exposures of 40% free time > minimum inhibitory concentration (40% fT > MIC) for Gram-negative organisms with susceptible MICs. Dosage regimens employing prolonged and continuous infusion regimens did provide appropriate pharmacodynamic exposures of 40% fT > MIC for Gram-negative organisms up to the break point for Pseudomonas aeruginosa of 4 mg/L. CONCLUSION These data suggest the reference dosage regimens for meropenem (20-40 mg/kg per dose every 8 hours) do not meet an appropriate pharmacodynamic target attainment in critically ill children ages 1 to 9 years. Based on these data, only the 3- to 4-hour prolonged infusion and 24-hour continuous infusion regimens were able to achieve an optimal probability of target attainment against all susceptible Gram-negative bacteria in critically ill children for 40% fT > MIC. Dosage regimens of 120 and 160 mg/kg/day as continuous infusion regimens may be necessary to achieve an optimal probability of target attainment against all susceptible Gram-negative bacteria in critically ill children for 80% fT > MIC. Based on these findings, confirmation with a larger, prospective investigation in critically ill children is warranted.

Abstract
An 11-year-old African American male with severe combined immunodeficiency variant, non-cystic fibrosis bronchiectasis, pancreatic insufficiency, chronic mycobacterium avium-intracellulare infection, chronic sinusitis, and malnutrition presented with a 1-week history of fevers. He subsequently developed respiratory decompensation and cefepime was discontinued and doripenem was initiated. Doripenem was the carbapenem used due to a national shortage of meropenem. By day 7 the patient (24.7 kg) had a positive fluid balance of 6925 mL (28% FO), and on days 7 into 8 developed acute kidney injury evidenced by an elevated serum creatinine of 0.68 mg/dL, an increase from the baseline of 0.28 mg/dL. On day 9, the patient was initiated on continuous renal replacement therapy (CRRT) and the doripenem dosing was changed to a continuous infusion of 2.5 mg/kg/hr (60 mg/kg/day). Approximately 12.5 hours after the start of the doripenem a serum concentration was obtained, which was 4.01 mg/L corresponding to a clearance of 10.5 mL/min/kg. The pediatric dosing and pharmacokinetic data available for doripenem suggest a clearance estimate of 4.4 to 4.8 mL/min/kg, and the adult clearance estimate is 2.4 to 3.78 mL/min/kg. The calculated clearance in our patient of 10.5 mL/min/kg is over double the highest clearance estimate in the pediatric literature. This case demonstrates that doripenem clearance is significantly increased with CRRT in comparison with the published pediatric and adult data. An appropriate pharmacodynamic outcome (time that free drug concentration > minimum inhibitory concentration) can be achieved by continuous infusion doripenem with concurrent therapeutic drug monitoring.

Abstract
BACKGROUND Quality of care is a major focus in the intensive care unit (ICU). AIM To describe a nurse-initiated quality improvement (QI) project that improved the care of critically ill patients in a New Zealand tertiary ICU. DESIGN A framework for QI was developed and implemented as part of a practice change initiative. METHODS Audit data were collected, analysed and reported across seven nurse-influenced patient care standards. The seven standards were enteral nutrition delivered within 24 h of admission, timely administration of antibiotics, sedation holds for eligible patients, early mobilization and three pressure ulcer prevention strategies. RESULTS Comparison of audit data collected in 2014 and 2015 demonstrated improvements in five of the seven standards. Those standards with the largest practice improvements were related to the following standards: all eligible patients have enteral nutrition commenced within the first 24 h of ICU admission (3% increase); all eligible patients receive antibiotics within 30 min of prescription time (6% increase); all eligible patients have a daily sedation interruption (DSI; 24% increase); and all eligible patients are mobilized daily in their ICU stay (11% increase in percentage of patients mobilized daily). CONCLUSIONS The nursing-initiated QI project demonstrated improved ICU patient care in relation to early enteral nutrition commencement, DSIs and early and daily mobilizing. RELEVANCE TO CLINICAL PRACTICE The use of a nursing QI framework incorporating audit and feedback is one method of evaluating and enhancing the quality of care and improving patient outcomes. This initiative demonstrated the improved quality of nursing care for ICU patients, particularly in relation to early enteral nutrition commencement, timely antibiotics, DSIs and daily mobilizing. It is thus highly relevant to critical care nursing teams, particularly those working to create a culture where change is safe, achievable and valued.

Abstract
PURPOSE With a decreasing supply of antibiotics that are effective against the pathogens that cause sepsis, it is critical that we learn to use currently available antibiotics optimally. Pharmacokinetic studies provide an evidence base from which we can optimize antibiotic dosing. However, these studies are challenging in critically ill neonate and pediatric patients due to the small blood volumes and associated risks and burden to the patient from taking blood. We investigate whether microsampling, that is, obtaining a biologic sample of low volume (<50 μL), can improve opportunities to conduct pharmacokinetic studies. METHODS We performed a literature search to find relevant articles using the following search terms: sepsis, critically ill, severe infection, intensive care AND antibiotic, pharmacokinetic, p(a)ediatric, neonate. For microsampling, we performed a search using antibiotics AND dried blood spots OR dried plasma spots OR volumetric absorptive microsampling OR solid-phase microextraction OR capillary microsampling OR microsampling. Databases searched include Web of Knowledge, PubMed, and EMbase. FINDINGS Of the 32 antibiotic pharmacokinetic studies performed on critically ill neonate or pediatric patients in this review, most of the authors identified changes to the pharmacokinetic properties in their patient group and recommended either further investigations into this patient population or therapeutic drug monitoring to ensure antibiotic doses are suitable. There remain considerable gaps in knowledge regarding the pharmacokinetic properties of antibiotics in critically ill pediatric patients. Implementing microsampling in an antibiotic pharmacokinetic study is contingent on the properties of the antibiotic, the pathophysiology of the patient (and how this can affect the microsample), and the location of the patient. A validation of the sampling technique is required before implementation. IMPLICATIONS Current antibiotic regimens for critically ill neonate and pediatric patients are frequently suboptimal due to a poor understanding of altered pharmacokinetic properties. An assessment of the suitability of microsampling for pharmacokinetic studies in neonate and pediatric patients is recommended before wider use. The method of sampling, as well as the method of bioanalysis, also requires validation to ensure the data obtained reflect the true result.

Abstract
INTRODUCTION Bronchopneumonia is the most common clinical manifestation of pneumonia in pediatric population and leading infectious cause of mortality in children under 5 years. Evaluation of treatment involves diagnostic procedures, assessment of disease severity and treatment for disease with an emphasis on vulnerability of the population. AIM To determine the most commonly used antibiotics at the Pediatric Clinic in Sarajevo and concomitant therapy in the treatment of bronchopneumonia. PATIENTS AND METHODS The study was retrospective and included a total of 104 patients, hospitalized in pulmonary department of the Pediatric Clinic in the period from July to December 2014. The treatment of bronchopneumonia at the Pediatric Clinic was empirical and it conformed to the guidelines and recommendations of British Thoracic Society. RESULTS AND DISCUSSION First and third generation of cephalosporins and penicillin antibiotics were the most widely used antimicrobials, with parenteral route of administration and average duration of treatment of 4.3 days. Concomitant therapy included antipyretics, corticosteroids, leukotriene antagonists, agonists of β2 adrenergic receptor. In addition to pharmacotherapy, hospitalized patients were subjected to a diet with controlled intake of sodium, which included probiotic-rich foods and adequate hydration. Recommendations for further antimicrobial treatment include oral administration of first-generation cephalosporins and penicillin antibiotics. CONCLUSION Results of the drug treatment of bronchopneumonia at the Pediatric Clinic of the University Clinical Center of Sarajevo are comparable to the guidelines of the British Thoracic Society. It is necessary to establish a system for rational use of antimicrobial agents in order to reduce bacterial resistance.

Abstract
OBJECTIVES To describe our experience with achieving therapeutic serum vancomycin concentrations in pediatric continuous renal replacement therapy by using continuous infusion vancomycin by mixing vancomycin into the continuous renal replacement therapy solution. DESIGN Retrospective chart review. SETTING A 189-bed, freestanding children's tertiary care teaching hospital in Philadelphia, PA. PATIENTS Pediatric patients receiving continuous renal replacement therapy from April 1, 2009, through December 31, 2014. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS There were a total of 21 patients who received continuous renal replacement therapy during the study period. Of these, 11 (52.3%) received vancomycin in the continuous renal replacement therapy solution. The median (range) concentration of vancomycin added to the continuous renal replacement therapy solution was 25 mg/L (18-35 mg/L). The mean vancomycin plateau level was 22.8 ± 3.3 mg/L. All patients achieved a serum vancomycin plateau level that was greater than 15 mg/L. There were no adverse events related to the addition of vancomycin to the continuous renal replacement therapy solution. CONCLUSIONS The addition of vancomycin to the continuous renal replacement therapy solution(s) is an effective modality that is used for delivering vancomycin continuous infusion and for ensuring therapeutic vancomycin serum plateau levels in the setting of pediatric continuous renal replacement therapy. Further studies are required to evaluate whether this delivery method can lead to improved patient outcomes.

Abstract
Pharmacokinetic parameters can be significantly altered for both extracorporeal life support (ECLS) and continuous renal replacement therapy (CRRT). This case report describes the pharmacokinetics of continuous-infusion meropenem in a patient on ECLS with concurrent CRRT. A 2.8-kg, 10-day-old, full-term neonate born via spontaneous vaginal delivery presented with hypothermia, lethargy, and a ~500-g weight loss from birth. She progressed to respiratory failure on hospital day 2 (HD 2) and developed sepsis, disseminated intravascular coagulation, and liver failure as a result of disseminated adenoviral infection. By HD 6, acute kidney injury was evident, with progressive fluid overload >1500 mL (+) for the admission. On HD 6 venoarterial ECLS was instituted for lung protection and fluid removal. On HD 7 she was initiated on CRRT. On HD 12, a blood culture returned positive and subsequently grew Pseudomonas aeruginosa with a minimum inhibitory concentration (MIC) for meropenem of 0.25 mg/L. She was started on vancomycin, meropenem, and amikacin. A meropenem bolus of 40 mg/kg was given, followed by a continuous infusion of 10 mg/kg/hr (240 mg/kg/day). On HD 15 (ECLS day 9) a meropenem serum concentration of 21 mcg/mL was obtained, corresponding to a clearance of 7.9 mL/kg/min. Repeat cultures from HDs 13 to 15 (ECLS days 7-9) were sterile. This meropenem regimen was successful in providing a target attainment of 100% for serum concentrations above the MIC for ≥40% of the dosing interval and was associated with a sterilization of blood in this complex patient on concurrent ECLS and CRRT circuits.

Abstract
We evaluated whether procalcitonin (PCT) might aid diagnosing serious bacterial infections in a general pediatric intensive care unit population. Two-hundred and one patients accounted for 332 PCT samples. A PCT ≥1.45 ng/mL had a positive predictive value of 30%, a negative predictive value of 93% and a sensitivity of 72% and a specificity of 75%. These data suggest PCT can assist in identifying patients without serious bacterial infections and limit antimicrobial use.

Abstract
INTRODUCTION Piperacillin/tazobactam is a frequently prescribed antibiotic in pediatric intensive care units, but pharmacokinetic data to justify the optimal piperacillin/tazobactam dosing regimen are sparse in critically ill children. METHODS Blood samples (2-4 per child) were collected from 13 children ages 9 months to 6 years admitted to the pediatric intensive care unit who were receiving standard piperacillin/tazobactam dosing regimens to treat infections. Piperacillin concentrations were measured by a bioassay, and the population pharmacokinetics of the piperacillin component was conducted using nonparametric adaptive grid (BigNPAG) with adaptive γ. Multiple models were tested to determine the best fit of the data. A 5000 patient Monte Carlo simulation was performed to determine the probability of target attainment (PTA) for piperacillin/tazobactam 50 mg/kg (of the piperacillin component) every 4 hours, 80 mg/kg every 8 hours and 100 mg/kg every 6 hours as 0.5-, 3- or 4-hour infusions in a population of 1- to 6-year-old male children. Centers for Disease Control and Prevention weight for age charts were used as weight distributions. The percent of the dosing interval of the free drug is above the minimum inhibitory concentration (MIC) (fT>MIC) was calculated over a range of MICs from 0.03 to 128 μg/mL. The bactericidal target attainment was defined as ≥50% fT>MIC for piperacillin/tazobactam. PTA ≥90% at each MIC was defined as optimal. RESULTS A 2 compartment model fitted piperacillin concentration data the best. Mean (standard deviation) population estimates for clearance, volume of the central compartment (Vc) and intercompartment transfer constants were 0.299 (0.128) L/hr/kg, 0.249 (0.211) L/kg, 6.663 (6.871) hours(-1) and 8.48 (7.74) hours(-1), respectively. This resulted in a mean (standard deviation) elimination half-life of 1.39 (0.62) hours. The bias, precision and r² for the individual predicted versus observed concentrations were -0.055, 0.96 μg/mL and 0.999, respectively. The only dosing regimens that achieved optimal PTA at the Clinical Laboratory Standards Institute susceptibility breakpoint of 16 μg/mL against Psuedomonas aeruginosa were 100 mg/kg every 6 hours administered as a 3-hour prolonged infusion and 400 mg/kg administered as a 24-hour continuous infusion. These dosing regimens also achieved 77.7% and 74.8% PTA, respectively, at a MIC of 32 μg/mL. CONCLUSION These are the first pharmacokinetic data of piperacillin/tazobactam (piperacillin component) in critically ill pediatric patients (1-6 years of age). Based on these data, 100 mg/kg q6h as a 3-hour infusion and 400 mg/kg continuous infusion were the only regimens to provide optimal PTA at the Clinical Laboratory Standards Institute breakpoint of 16 μg/mL.

Abstract
BACKGROUND Cystic fibrosis (CF) patients are often treated with aminoglycoside (AG) antibiotics during infective pulmonary exacerbations. Achieving pharmacokinetic and pharmacodynamic (PK/PD) targets to improve outcomes and counteract resistance is paramount. PURPOSE The primary objective was to compare the number of pediatric CF patients achieving AG PK/PD targets when a clinical pharmacist (CP) managed therapeutic drug monitoring (TDM) compared with usual care (UC). METHODS A retrospective cohort study was conducted on the records of 40 CF patients that received AGs and ≥2 serum samples between 1/2007 and 5/2009. Chi-square and Student's t-test were used to analyze nominal and continuous variables, respectively. RESULTS Twenty-nine patients with 52 courses of AGs were included the CP group, and 22 patients with 42 courses were included the UC group. Ninety-eight percent of patients in the CP group reached AG PK/PD targets compared with 71% in the UC group, P < 0.001. Patients in the CP group reached the AG PK/PD target in a mean of 1.9 ± 0.8 days compared with 4.8 ± 3.4 days in the UC group, P < 0.0001. The average LOS in the CP group was 9 ± 5 days compared with 12 ± 7.5 days in the UC group, P = 0.033. The mean number of levels per patient was 2.7 in the CP group compared with 5.2 (range of 2-20) in the UC group, P < 0.001. Resource utilization associated with drug levels, dosing adjustments and LOS were $26,549, $14,069, and $1,680,000 in the CP group as compared with $40,683, $27,812, and $1,940,000, respectively, in the UC group. CONCLUSION CP managed TDM resulted in a significantly higher percentage of pediatric CF patients achieving AG PK/PD targets 3 days sooner with an average LOS that was 3 days shorter. CP managed TDM resulted in significantly fewer dosage adjustments, drug levels, and cost associated with serum sampling, drug wastage, and LOS.

West J Emerg Med 2013; 14:518-24.

Abstract
Introduction: Early antibiotic administration is recommended in newborns presenting with febrile illness to emergency departments (ED) to avert the sequelae of serious bacterial infection. Although ED crowding has been associated with delays in antibiotic administration in a dedicated pediatric ED, the majority of children that receive emergency medical care in the United States present to EDs that treat both adult and pediatric emergencies. The purpose of this study was to examine the relationship between time to antibiotic administration in febrile newborns and crowding in a general ED serving both an adult and pediatric population. Methods: We conducted a retrospective chart review of 159 newborns presenting to a general ED between 2005 and 2011 and analyzed the association between time to antibiotic administration and ED occupancy rate at the time of, prior to, and following infant presentation to the ED. Results: We observed delayed and variable time to antibiotic administration and found no association between time to antibiotic administration and occupancy rate prior to, at the time of, or following infant presentation (p>0.05). ED time to antibiotic administration was not associated with hospital length of stay, and there was no inpatient mortality. Conclusion: Delayed and highly variable time to antibiotic treatment in febrile newborns was common but unrelated to ED crowding in the general ED study site. Guidelines for time to antibiotic administration in this population may reduce variability in ED practice patterns.

Abstract
The effect of delayed antifungal therapy in critically ill infants with invasive candidiasis has not been studied. Our objective was to evaluate the effect of time to initiation of antifungal therapy (TIA) on mortality, disseminated disease, and postinfection hospital stay. We conducted a cohort study of critically ill infants with cultures positive for Candida from 1990 to 2008. TIA was defined as the number of hours from the collection of the first positive culture until the start of antifungal therapy. Of 96 infants, 57% were male, the median gestational age was 27 weeks (range, 23 to 41 weeks), and the median birth weight was 956 g (range, 415 to 6,191 g). Most subjects received amphotericin B deoxycholate. TIA was ≤ 24 h for 35% of infants, between 25 and 48 h for 42%, and >48 h for 23%. Eleven subjects died during hospitalization, and 22% had disseminated candidiasis. The median duration of hospital stay postinfection was 53 days (range, 6 to 217 days). Both univariate and multivariate analyses demonstrated that TIA was not associated with mortality, disseminated disease, or hospital stay postinfection. However, ventilator use for >60 days significantly increased the risk of death (odds ratio [OR], 9.5; 95% confidence interval [CI], 2.2 to 66.7; P = 0.002). Prolonged candidemia increased the risk of disseminated disease by 10% per day of positive culture (OR, 1.1; 95% CI, 1.08 to 1.2; P = 0.007), and low gestational age was associated with increased neonatal intensive care unit (NICU) stay after the first positive Candida culture by 0.94 weeks (95% CI, 0.70 to 0.98; P < 0.001). The TIA was not associated with all-cause mortality, disseminated candidiasis, and postinfection length of hospital stay.

Abstract
Sepsis remains an important challenge in pediatric critical care medicine. This review provides an appraisal of adjunctive therapies for sepsis and highlights opportunities for meeting selected challenges in the field. Future clinical studies should address long-term and functional outcomes as well as acute outcomes. Potential adjunctive therapies such as corticosteroids, hemofiltration, hemoadsorption, and plasmapheresis may have important roles, but still require formal and more rigorous testing by way of clinical trials. Finally, the design of future clinical trials should consider novel approaches for stratifying outcome risks as a means of improving the risk-to-benefit ratio of experimental therapies.

Abstract
OBJECTIVE Duke University Health System (DUHS) generates annual antibiograms combining adult and pediatric data. We hypothesized significant susceptibility differences exist for pediatric isolates and that distributing these results would alter antibiotic choices. METHODS Susceptibility rates for Escherichia coli isolates from patients aged ≤12 years between July 2009 and September 2010 were compared with the 2009 DUHS antibiogram. Pediatric attending and resident physicians answered case-based vignettes about children aged 3 months and 12 years with urinary tract infections. Each vignette contained 3 identical scenarios with no antibiogram, the 2009 DUHS antibiogram, and a pediatric-specific antibiogram provided. Effective antibiotics exhibited >80% in vitro susceptibility. Frequency of antibiotic selection was analyzed by using descriptive statistics. RESULTS Three hundred seventy-five pediatric isolates were identified. Pediatric isolates were more resistant to ampicillin and trimethoprim-sulfamethoxazole (TMP-SMX) and less resistant to amoxicillin-clavulanate and ciprofloxacin (P < .0005 for all). Seventy-five resident and attending physicians completed surveys. In infant vignettes, physicians selected amoxicillin-clavulanate (P < .05) and nitrofurantoin (P < .01) more often and TMP-SMX (P < .01) less often with pediatric-specific data. Effective antibiotic choices increased from 68.6% to 82.2% (P = .06) to 92.5% (P < .01) across scenarios. In adolescent vignettes, providers reduced TMP-SMX use from 66.2% to 42.6% to 19.0% (P < .01 for both). Effective antibiotic choices increased from 32.4% to 57.4% to 79.4% (P < .01 and P = .01). CONCLUSIONS Pediatric E. coli isolates differ significantly in antimicrobial susceptibility at our institution, particularly to frequently administered oral antibiotics. Knowledge of pediatric-specific data altered empirical antibiotic choices in case vignettes. Care of pediatric patients could be improved with use of a pediatric-specific antibiogram.

Abstract
BACKGROUND Pneumonia is the leading cause of childhood mortality worldwide. The World Health Organization recommends presumptive treatment based on clinical syndromes. Recent studies raise concerns over the frequency of treatment failure in Africa. METHODS We applied a definition of treatment failure to data prospectively collected from children who were 2-59 months of age with severe, or very severe, pneumonia admitted to Kilifi District Hospital, Kenya, from May 2007 through May 2008 and treated using World Health Organization guidelines. The primary outcome was treatment failure at 48 hours. RESULTS Of 568 children, median age 11 months, 165 (29%) had very severe pneumonia, 30 (5.3%) a positive HIV test and 62 (11%) severe malnutrition. One hundred eleven (20%; 95% confidence interval: 17-23%) children failed treatment at 48 hours and 34 (6.0%) died; 22 (65%) deaths occurred before 48 hours. Of 353 children with severe pneumonia, without HIV or severe malnutrition, 42 (12%) failed to respond at 48 hours, 15 (4.3%) failed at 5 days and 1 child (0.3%) died. Among 215 children with either severe pneumonia complicated by HIV or severe malnutrition, or very severe pneumonia, 69 (32%) failed to treatment at 48 hours, 47 (22%) failed at 5 days and 33 (16%) died. Treatment failure at 48 hours was associated with shock, bacteremia, very severe pneumonia, oxygen saturation in hemoglobin <95%, severe malnutrition, HIV and age <1 year in multivariable models. CONCLUSIONS In this setting, few children with uncomplicated severe pneumonia fail treatment or die under current guidelines. Deaths mainly occurred early and may be reduced by improving prevention, prehospital care and treatment of sepsis.

Abstract
Infectious diseases, besides being a major cause of mortality in developing countries, are one of the main reasons for consultation in emergency medicine. In the last few years, there have been numerous published studies on the importance of starting antibiotic treatment at an early stage in the Emergency Department. However, this issue is of great controversy, owing to some contradictory studies as well as the implications this may have on the pressure of the patient care. This review is presents a summary of the scientific evidence published in this regard, and makes some recommendations based on this published evidence to improve the initial management of patients with an infection; a question of great importance as it can reduce mortality in some specific situations.

Abstract
Background Community-acquired pneumonia (CAP) is a common childhood infection. CAP complications, such as parapneumonic empyema (PPE), are increasing and are frequently caused by antibiotic-resistant organisms. No clinical guidelines currently exist for management of pediatric CAP and no published data exist about variations in antibiotic prescribing patterns. Our objectives were to describe variation in CAP clinical management for hospitalized children by pediatric infectious disease consultants and to examine associations between recommended antibiotic regimens and local antibiotic resistance levels. Methods We surveyed pediatric members of the Emerging Infections Network, which consists of 259 pediatric infectious disease physicians. Participants responded regarding their recommended empiric antibiotic regimens for hospitalized children with CAP with and without PPE and their recommendations for duration of therapy. Participants also provided information about the prevalence of penicillin non-susceptible S. pneumoniae and methicillin-resistant S. aureus (MRSA) in their community. Results We received 148 responses (57%). For uncomplicated CAP, respondents were divided between recommending beta-lactams alone (55%) versus beta-lactams in combination with another class (40%). For PPE, most recommended a combination of a beta-lactam plus an anti-MRSA agent, however, they were divided between clindamycin (44%) and vancomycin (57%). The relationship between reported antibiotic resistance and empiric regimen was mixed. We found no relationship between aminopenicillin use and prevalence of penicillin non-suscepetible S. pneumoniae or clindamycin use and clindamycin resistance, however, respondents were more likely to recommend an anti-MRSA agent when MRSA prevalence increased. Conclusions Substantial variability exists in recommendations for CAP management. Development of clinical guidelines via antimicrobial stewardship programs and dissemination of data about local antibiotic resistance patterns represent opportunities to improve care.
