Abstract

<p><strong>BACKGROUND: </strong>Systems for standardizing physician payment have been shown to undervalue cognitive clinical encounters. Because health care reform emphasizes value-based approaches, we need an understanding of the way pediatric cognitive specialties are used to contribute to the provision of high-value care. We sought to investigate how clinical and administrative stakeholders perceive the value of pediatric infectious disease (PID) specialists.</p>

<p><strong>METHODS: </strong>We conducted qualitative interviews with a purposive sample of physicians and administrators from 5 hospitals across the United States in which children are cared for. All interviews were transcribed and systematically analyzed for common themes.</p>

<p><strong>RESULTS: </strong>We interviewed 97 stakeholders. Analysis revealed the following 3 domains of value: clinical, organizational, and communicative. Clinically, PID specialists were perceived to be highly valuable in treating patients with unusual infections that respond poorly to therapy, in optimizing the use of antimicrobial agents and in serving as outpatient homes for complex patients. Respondents perceived that PID specialists facilitate communication with patients and their families, the health care team and the media. PID specialists were perceived to generate value by participating in systemwide activities, including antimicrobial stewardship and infection prevention. Despite this, much of the valuable work PID specialists perform is difficult to measure causing some administrative stakeholders to question how many PID specialists are necessary to achieve high-quality care.</p>

<p><strong>CONCLUSIONS: </strong>With our findings, we suggest that pediatric cognitive specialties contribute value in multiple ways to the health care delivery system. Many of these domains are difficult to capture by using current metrics, which may lead administrators to overlook valuable work and to under-allocate resources.</p>

Abstract

<p><strong>OBJECTIVES: </strong>Cutaneous lesions are often the first marker of invasive mold infection, which can cause substantial morbidity in immunocompromised children. The purpose of this study was to describe the evaluation and outcomes of immunocompromised children who presented with findings requiring skin biopsy because of concern about invasive infection. In children who were biopsied, we sought to determine the factors predictive of invasive mold infection.</p>

<p><strong>METHODS: </strong>A retrospective review was conducted at the Children's Hospital of Philadelphia. Patients included in the study were immunocompromised individuals younger than 26 years old who underwent skin biopsy by the inpatient dermatology consultation team between January 1, 2003, and March 15, 2015, because of development of new cutaneous lesions that were suspected of being invasive infection.</p>

<p><strong>RESULTS: </strong>One hundred five encounters met the inclusion criteria. Fifty (47.6%) biopsied individuals had an infectious pathogen identified on histopathology or culture. Mold was the most common (36%) pathogen, followed by bacteria (32%) and yeast (26%). The presence of a single lesion (P = .001) and prior occlusion at the site of the lesion (P &lt; .001) were associated with mold on biopsy. The combination of a single lesion, history of occlusion, and tissue necrosis on examination was highly predictive for invasive mold infection (86.3% [95% confidence interval 55.1-97.0%]). Of the 18 individuals with confirmed invasive mold infection, 13 (72%) underwent surgical resection, of whom 12 (92%) survived the 30-day follow-up period.</p>

<p><strong>CONCLUSION: </strong>Skin biopsy enabled the detection of a pathogen that informed directed therapeutic interventions in nearly half of participants. Institutions caring for immunocompromised children should ensure adequate staffing of clinical personnel approved to perform skin biopsies.</p>

Abstract

<p><strong>Background: </strong>Parental pressure is often cited as a reason for why pediatricians overuse antibiotics for children with acute respiratory tract infection (ARTI). We sought to capture parent perceptions of antibiotics at the time of their child's presentation with an ARTI.</p>

<p><strong>Methods: </strong>We conducted semistructured interviews with parents of children who presented with ARTI symptoms to 1 of 4 diverse practices in a large hospital-affiliated network of pediatric primary care practices. Parents were interviewed before their child was seen by the pediatrician and asked about their perceptions of antibiotics.</p>

<p><strong>Results: </strong>Interviews were conducted with 109 parents. None of the parents said they planned to ask the pediatrician for antibiotics but instead expected to gain reassurance and a plan to minimize symptoms. Three perceptions about antibiotics were identified: parents have a sense of wariness when their child is prescribed antibiotics, they have an understanding that antibiotic overuse is a problem but that it is driven by the demands of other parents, and they have a preference for alternative treatment. The majority of the parents were not concerned about antibiotic resistance. In response to closed-ended questions designed to assess their level of concern with adverse effects, parents were most concerned with their child developing an upset stomach, having an allergic reaction, and experiencing diarrhea. The parents were not concerned with antibiotic treatment failure.</p>

<p><strong>Conclusions: </strong>Parents in our study expressed a sense of caution about antibiotics and an awareness that they should be used judiciously. Our findings indicate that parents are aware of the downsides of antibiotics and might be willing to partner with healthcare providers to improve appropriate use.</p>

Abstract

<p><strong>Background: </strong>Solid organ transplant (SOT) recipients are at risk for invasive fungal disease (IFD). Data on IFD burden in pediatric patients are limited. We aimed to determine the incidence and outcome of IFD in a large cohort of pediatric patients who underwent SOT.</p>

<p><strong>Methods: </strong>A single-center cohort of pediatric patients who underwent SOT between 2000 and 2013 was assembled retrospectively. The patients were followed for 180 days after transplant or until death to determine the presence or absence of IFD. The 2008 European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group Consensus Group criteria were used to define IFD as proven or probable. The incidence of IFD, all-cause mortality rate, and case-fatality rate at 180 days were calculated.</p>

<p><strong>Results: </strong>Among 584 pediatric patients who underwent SOT, 13 patients sustained 14 episodes of IFD (candidiasis, aspergillosis, and mucormycosis). The overall incidence was 2.2% (14.3 IFD events per 100000 patient-days). The IFD rates according to transplant type were 12.5% (1 of 8) (heart/lung), 11.4% (4 of 35) (lung), 4.7% (8 of 172) (liver), 0% (0 of 234) (kidney), and 0% (0 of 135) (heart). Three patients with IFD (2 lung and 1 heart/lung) died, and all these deaths were deemed likely attributable to the IFD; the case-fatality rate was 21.4% (3 of 14).</p>

<p><strong>Conclusions: </strong>The overall incidence of IFD in these pediatric SOT recipients was low but varied across transplant type, with heart/lung and lung recipients having the highest IFD rate. Given the attributable case-fatality rate, the risk of death resulting from IFD is potentially high. More data on groups at higher risk, such as lung transplant recipients, are needed to guide targeted antifungal prophylaxis.</p>

Abstract

<p>Human adenovirus (HAdV) is one of the most feared infections among immunocompromised patients. In particular, in liver transplant patients, HAdV has been implicated in acute liver failure with resultant mortality. The development of current molecular techniques and surveillance testing protocols have provided tools for early detection of HAdV infection, prior to or at the early onset of HAdV disease. Although reduction in immune suppression is the mainstay of therapy, many researchers have also advocated for early administration of antiviral therapy. In multiple reports, cidofovir treatment has been associated with declines in HAdV viral loads or clinical improvement in solid organ and bone marrow transplant recipients. However, there have also been case reports that raise questions about the effectiveness of antiviral therapy in controlling systemic HAdV disease. We report a case of a 26-month-old male recipient of a liver transplantation for hepatoblastoma who developed adenoviremia with an associated hepatitis and gastroenteritis. He recovered with reduced immune suppression but without antiviral therapy, thus avoiding potential toxicities associated with cidofovir therapy. This case a contrast to previous reports, and it highlights the ambiguity regarding which patients should receive HAdV-specific antiviral therapy. Additional knowledge regarding specific pediatric host factors and HAdV factors that predict poor outcomes are needed. Such information would allow clinicians to better stratify patients by risk at the time of adenoviremia detection so that low-risk patients are not unnecessarily exposed to medications with potential toxicities.</p>

Abstract

<p><strong>BACKGROUND: </strong>Biomarkers that identify critically ill children with systemic inflammatory response syndrome (SIRS) at low risk for bacterial infection may help clinicians reduce unnecessary antibiotic use.</p>

<p><strong>METHODS: </strong>We conducted a prospective cohort study of children with SIRS and suspected infection admitted to a pediatric intensive care unit from January 5, 2012 to March 7, 2014. We enrolled patients upon initiation of new antibiotics (Time 0) and measured a panel of 8 serum biomarkers daily over 72 hours. Microbiology, imaging, and clinical data were reviewed to classify bacterial infections using Centers for Disease Control and Prevention definitions. We identified cut points of biomarker combinations to maximize the negative predictive value (NPV) and specificity for bacterial infection. Excess antibiotics were calculated as days of therapy beyond day 2 after SIRS onset in patients without bacterial infection.</p>

<p><strong>RESULTS: </strong>Infections were identified in 46 of 85 patients: bacterial (n = 22) and viral (24), whereas 39 patients had no infection identified. At Time 0, C-reactive protein (CRP) &lt;5 mg/dL plus serum amyloid A &lt;15.0 µg/mL had an NPV of 0.92 (95% confidence interval [CI], 0.79-1.0) and specificity of 0.54 (95% CI, 0.42-0.66) to identify patients without bacterial infection, whereas CRP &lt;4 mg/dL plus procalcitonin &lt;1.75 ng/mL had an NPV of 0.90 (95% CI, 0.79-1.0) and specificity of 0.43 (95% CI, 0.30-0.55). Patients without bacterial infection received a mean of 3.8 excess days of therapy.</p>

<p><strong>CONCLUSIONS: </strong>Early measurement of select biomarkers can identify children with SIRS in whom antibiotics might be safely discontinued when there is no other objective evidence of infection at 48 hours.</p>

Abstract

<p>Prolonged OR, re-transplantation, and high-volume intraoperative transfusion have been associated with increased risk for IC in adult LT recipients. Antifungal prophylaxis is recommended for adult patients with these risk factors. There are limited data on the incidence of and risk factors for IC in pediatric LT recipients. A retrospective cohort study of all pediatric LT patients at the CHOP between 2000 and 2012 and the CHP between 2004 and 2012 was performed to define the incidence of IC within 30 days of LT. A 3:1 matched case-control study with incidence density sampling was performed. Conditional logistic regression analyses were used to explore risk factors associated with IC. Among 397 recipients, the incidence of IC was 2.5%. Bivariate analyses showed that ICU admission prior to transplant, OR &gt; 10 h, intraoperative volume infusion of &gt;300 mL/kg, and broad-spectrum antibiotics were significantly associated with IC. In a multivariate model, only ICU admission remained significantly associated with IC. Antifungal prophylaxis was not significantly protective against IC. The low incidence of IC and lack of an identified protective effect from antifungal prophylaxis suggest that prophylaxis in pediatric LT recipients should not be routinely recommended to prevent IC events in the first 30 days post-transplant.</p>

Abstract

<p><strong>BACKGROUND: </strong>Human adenoviruses (HAdV) are known opportunistic pathogens in hematopoietic stem cell transplant (SCT) recipients. The detection of HAdV infection in children after SCT has been implicated as a determinant of poor outcome but specific associations between HAdV species or individual HAdV types and disease are poorly understood.</p>

<p><strong>OBJECTIVES: </strong>Characterization of a HAdV-D strain isolated from multiple clinical specimens of an 11-year-old female recipient of a matched unrelated donor peripheral SCT for T-cell lymphoma and case report.</p>

<p><strong>STUDY DESIGN: </strong>Archived HAdV PCR-positive plasma, urine, and stool specimens were processed for virus isolation and detailed molecular typing. Complete genomic sequencing was carried out on 2 isolates.</p>

<p><strong>RESULTS: </strong>The patient tested positive for HAdV DNA by real-time PCR of a stool specimen at 44 days after initiation of a SCT conditioning regimen. In the subsequent 3 months, HAdV was detected in plasma, urine and stool specimens in association with symptoms of gastroenteritis and hemorrhagic cystitis. A novel HAdV-D with a HAdV20-like hexon gene was isolated from both urine and stool specimens. All isolates yielded identical restriction profiles with endonucleases BamHI, BglII, BstEII, HindIII, PstI and SmaI. Analysis of 2 complete genomic sequences further identified the virus as a novel intertypic recombinant HAdV-D (P20/H20/F42) closely related to HAdV42.</p>

<p><strong>CONCLUSIONS: </strong>This case highlights the identification of a previously unknown HAdV-D from an immunocompromised host. In this patient, the course of adenovirus infection is compatible with reactivation of a latent virus or a primary opportunistic infection. Adenoviremia in this patient resolved without definitive adenovirus-directed antiviral therapy.</p>

Abstract

<p><strong>OBJECTIVE: </strong>To develop a candidate definition for central line-associated bloodstream infection (CLABSI) in neonates with presumed mucosal barrier injury due to gastrointestinal (MBI-GI) conditions and to evaluate epidemiology and microbiology of MBI-GI CLABSI in infants.</p>

<p><strong>DESIGN: </strong>Multicenter retrospective cohort study.</p>

<p><strong>SETTING: </strong>Neonatal intensive care units from 14 US children's hospitals and pediatric facilities.</p>

<p><strong>METHODS: </strong>A multidisciplinary focus group developed a candidate MBI-GI CLABSI definition based on presence of an MBI-GI condition, parenteral nutrition (PN) exposure, and an eligible enteric organism. CLABSI surveillance data from participating hospitals were supplemented by chart review to identify MBI-GI conditions and PN exposure.</p>

<p><strong>RESULTS: </strong>During 2009-2012, 410 CLABSIs occurred in 376 infants. MBI-GI conditions and PN exposure occurred in 149 (40%) and 324 (86%) of these 376 neonates, respectively. The distribution of pathogens was similar among neonates with versus without MBI-GI conditions and PN exposure. Fifty-nine (16%) of the 376 initial CLABSI episodes met the candidate MBI-GI CLABSI definition. Subsequent versus initial CLABSIs were more likely to be caused by an enteric organism (22 of 34 [65%] vs 151 of 376 [40%]; P = .009) and to meet the candidate MBI-GI CLABSI definition (19 of 34 [56%] vs 59 of 376 [16%]; P &lt; .01).</p>

<p><strong>CONCLUSIONS: </strong>While MBI-GI conditions and PN exposure were common, only 16% of initial CLABSIs met the candidate definition of MBI-GI CLABSI. The high proportion of MBI-GI CLABSIs among subsequent infections suggests that infants with MBI-GI CLABSI should be a population targeted for further surveillance and interventional research.</p>
