RESUMO
BACKGROUND: The utility of peripheral blood cultures in pediatric oncology patients presenting with fever is controversial. A recent systematic review showed that about one in 40 bloodstream infections (BSIs) would be missed if only central venous line (CVL) cultures are obtained. OBJECTIVE: To derive a clinical decision rule for obtaining peripheral blood cultures in pediatric oncology patients presenting to a pediatric emergency department (PED) with fever and a CVL. DESIGN/METHOD: A retrospective chart review was performed on pediatric oncology patients referred to the PED for fever while on therapy. Logistic regression with a random intercept was used to determine independent predictors of BSI and generate a prediction model for obtaining peripheral blood cultures. The decision rule was generated from the best performance as measured by a receiver operator curve. Bootstrapping analysis was performed for internal validation. RESULTS: Predictors that were significant and independently associated with positive peripheral blood cultures included vasopressor support (odds ratio [OR] 16.5, 95% confidence interval [CI]: 2.80-97.71), acute myeloid leukemia (AML) diagnosis (OR 6.9, 95% CI: 1.81-25.98), hypotension (OR 4.0, 95% CI: 1.05-15.17), mucositis (OR 8.2, 95% CI: 2.48-27.01), and maximum temperature in PED ≥39°C (OR 6.6, 95% CI: 2.36-18.20). The area under the curve (AUC) for this model was 0.90 (95% CI: 0.82-0.97) in the derivation cohort and 0.90 (95% CI: 0.81-0.98) after the internal validation. CONCLUSIONS: We derived a clinical prediction model for deciding when to obtain peripheral blood cultures in febrile oncology patients with CVLs on active therapy. Future studies should focus on prospective and external validation of this diagnostic prediction tool.

Acute promyelocytic leukemia (APL) is associated with a favorable long-term prognosis if appropriate treatment is initiated promptly. Outcomes in clinical trials and population-based registries vary; potential explanations include a delay in treatment and lower adherence to guideline-recommended therapy in real-world practice. We used the Vizient Clinical Data Base to describe demographic characteristics, baseline clinical characteristics, and treatment patterns in patients newly diagnosed with APL during the study period of April 2017 to March 2020. Baseline white blood cell count was used to assign risk status and assess treatment concordance with National Comprehensive Cancer Network guidelines. Logistic regression models examined adjusted associations between patient, hospital, disease characteristics, and adverse outcomes (in-hospital death or discharge to hospice). Among 1464 patients with APL, 205 (14.0%) experienced an adverse outcome. A substantial subset (20.6%) of patients did not receive guideline-concordant regimens. Odds of adverse outcomes increased with failure to receive guideline-concordant treatment (odds ratio [OR], 2.31; 95% confidence interval [CI], 1.43-3.75; P = .001), high-risk disease (OR, 2.48; 95% CI, 1.53-4.00; P < .001), and increasing age (≥60 years: OR, 11.13; 95% CI, 4.55-27.22; P < .001). Higher hospital acute myeloid leukemia (AML) patient volume was associated with lower odds of adverse outcome (OR, 0.44; 95% CI, 0.20-0.99 [for ≤50 vs >200 AML patients per year]; P = .046). In conclusion, in this large database analysis, 14.0% of patients newly diagnosed with APL died or were discharged to hospice. A substantial proportion of patients did not receive guideline-concordant therapy, potentially contributing to adverse outcomes.

OBJECTIVE: To describe medication utilization patterns by pediatric inpatients with cancer during their last week of life. METHODS: This retrospective study used data from the Vizient Clinical Database/Resource Manager, a national compilation of clinical and resource use data from over 100 academic medical centers and affiliates. Patients (0-21 years) with malignancy who died during hospitalization (2010-2017) were included (N = 1659). Medications were categorized as opioid, benzodiazepine, gastrointestinal related, chemotherapy, anti-infectives, or vasopressors. Exposure to each group was ascertained for all patients at 1 week and 1 day prior to death. Factors associated with exposure were examined using generalized estimating equations, and summarized using adjusted odds ratios (aORs). RESULTS: Over the last week of life, there was increased use of opioids (76% to 82%, aOR = 1.55, P < .001) and benzodiazepines (53% to 66%, aOR = 1.36, P = .02), while gastrointestinal-related medication use decreased (92% to 89%, aOR = 0.69, P = .001). Patients had decreased exposure to chemotherapy (10% to 5%, aOR = 0.46, P < .001) and anti-infectives (82% to 73%, aOR = 0.41, P = .002). Vasopressor use increased as death approached (15% to 28%, aOR = 1.67, P = .04). Factors significantly associated with exposure varied with medication category, and included age, race, length of stay, malignancy type, death in the intensive care unit, history of hematopoietic stem cell transplant, and do-not-resuscitate status. CONCLUSION: During the week preceding death, administration of symptom management medications increased for children with cancer, but use was not universal. Potentially life-sustaining medications were often continued. Variability in utilization suggests differences in provider/family decision making that warrant further study to develop an evidence-based approach to end-of-life care.

BACKGROUND: Hypersensitivity reactions to etoposide have been reported and patients have been safely transitioned to etoposide phosphate for continued therapy. However, the safety and efficacy of substituting etoposide phosphate for etoposide has not been well established in pediatric orthopedic malignancies. The aim of this study is to determine whether etoposide phosphate can be substituted for etoposide in pediatric orthopedic malignancies. METHODS: A chart review of pediatric patients who developed hypersensitivity reactions to etoposide while being treated for orthopedic malignancies was performed at a large academic medical center. Three patients were identified, two with Ewing sarcoma and one with an osteosarcoma. All three patients experienced hypersensitivity reactions to their first doses of etoposide and were switched to etoposide phosphate for further therapy. RESULTS: After premedication, all three patients tolerated full doses of etoposide phosphate without a graded dose challenge or desensitization. Two of the patients were premedicated with diphenhydramine alone, while the third received diphenhydramine and dexamethasone. CONCLUSIONS: Etoposide phosphate is a potentially safe alternative for pediatric patients with orthopedic malignancies who experience etoposide hypersensitivity. However, caution is needed as there are cases of etoposide phosphate hypersensitivity.

The objective was to decrease the time to antibiotic administration for patients arriving in the pediatric emergency department with fever and neutropenia. A multidisciplinary team was assembled and engaged in process analysis through interviews and data review. These findings were used to develop key drivers, and Pareto charts were utilized to prioritize interventions. Interventions were tested and implemented using rapid Plan-Do-Study-Act cycles. Progress was monitored using process control charts. Interventions included leveraging a secure text-based messaging platform, creating a new antibiotic pathway, and educating staff and family. Between September 2016 and September 2017, the average time to antibiotics was decreased from 116 to 55 minutes in this population. This also was associated with a decrease in variation (individual moving range mean decreased from 43 minutes to 18 minutes). Careful process analysis, coupled with the work of a multidisciplinary team, produced significant improvements in efficiency of care for these vulnerable patients.
