Clinical decision support to enhance venous thromboembolism pharmacoprophylaxis prescribing for pediatric inpatients with COVID-19.

OBJECTIVE: To design and evaluate a clinical decision support (CDS) module to improve guideline concordant venous thromboembolism (VTE) pharmacoprophylaxis prescribing for pediatric inpatients with COVID-19. MATERIALS AND METHODS: The proportion of patients who met our institutional clinical practice guideline's (CPG) criteria for VTE prophylaxis was compared to those who triggered a CDS alert, indicating the patient needed VTE prophylaxis, and to those who were prescribed prophylaxis pre and post the launch of a new VTE CDS module to support VTE pharmacoprophylaxis prescribing. The sensitivity, specificity, positive predictive value (PPV), negative predictive value, F1-score and accuracy of the tool were calculated for the pre- and post-intervention periods using the CPG recommendation as the gold standard. Accuracy was defined as the sum of the true positives and true negatives over the sum of the true positives, false positives, true negatives, and false negatives. Logistic regression was used to identify variables associated with correct thromboprophylaxis prescribing. RESULTS: A significant increase in the proportion of patients triggering a CDS alert occurred in the post-intervention period (44.3% vs. 6.9%, p < .001); however, no reciprocal increase in VTE prophylaxis prescribing was achieved (36.6% vs. 40.9%, p = .53). The updated CDS module had an improved sensitivity (55.0% vs. 13.3%), NPV (44.9% vs. 36.3%), F1-score (66.7% vs. 23.5%), and accuracy (62.5% vs. 42.0%), but an inferior specificity (78.6% vs. 100%) and PPV (84.6% vs. 100%). DISCUSSION: The updated CDS model had an improved accuracy and overall performance in correctly identifying patients requiring VTE prophylaxis. Despite an increase in correct patient identification by the CDS module, the proportion of patients receiving appropriate pharmacologic prophylaxis did not change. CONCLUSION: CDS tools to support correct VTE prophylaxis prescribing need ongoing refinement and validation to maximize clinical utility.

Brentuximab vedotin after autologous transplantation in pediatric patients with relapsed/refractory Hodgkin lymphoma.

Outcomes for children and adolescents with relapsed and refractory Hodgkin lymphoma (HL) are poor, with ∼50% of patients experiencing a subsequent relapse. The anti-CD30 antibody-drug conjugate brentuximab vedotin improved progression-free survival (PFS) when used as consolidation after autologous stem cell transplantation (ASCT) in adults with high-risk relapsed/refractory HL. Data on brentuximab vedotin as consolidative therapy after ASCT in pediatric patients with HL are extremely limited, with data of only 11 patients reported in the literature. We performed a retrospective analysis of 67 pediatric patients who received brentuximab vedotin as consolidation therapy after ASCT for the treatment of relapsed/refractory HL to describe the experience of this regimen in the pediatric population. This is the largest cohort reported to date. We found that brentuximab vedotin was well tolerated with a safety profile similar to that of adult patients. With a median follow-up of 37 months, the 3-year PFS was 85%. These data suggest a potential role for the use of brentuximab vedotin as consolidation therapy after ASCT for children with relapsed/refractory HL.

Glucose 6 Phosphate Isomerase Deficiency, a Rare Hemolytic Anemia Misdiagnosed as Hereditary Spherocytosis.

Hereditary hemolytic anemias are a heterogenous group of disorders that include membranopathies, enzymopathies, and hemoglobinopathies. Genetic testing is helpful in the diagnostic workup when the clinical and laboratory workup is not conclusive. Here, we present a case of a 21-month-old female who was initially diagnosed with hereditary spherocytosis based on the presence of a variant of unknown significance in the SPTB gene. Further genetic workup revealed a homozygous glucose 6 phosphate isomerase mutation and the patient was ultimately diagnosed with glucose 6 phosphate isomerase deficiency.

How I approach: The workup and management of patients with progressive transformation of the germinal center.

Progressive transformation of the germinal center (PTGC) is a common and underrecognized cause of pediatric lymphadenopathy. PTGC may be associated with numerous systemic medical conditions that require further workup and management, including malignancy, autoimmune conditions, lymphoproliferative conditions, immunodeficiency, and infection. Given the breadth and rarity of the associated conditions, workup should be tailored to the individual patient and occur in a tiered approach. Patients with PTGC require ongoing follow-up, given their long-term risk of malignancy and recurrent PTGC.

Impact of a Residential Summer Camp Experience on Children With Sickle Cell Disease.

Background: Sickle cell disease (SCD) has a significant psychosocial impact on affected children. Summer camp has been shown to improve psychological and physical states for children with diabetes and cancer. However, opportunities to attend camp for children with SCD are limited, as many are from low-income families, and many camps are not equipped to care for children with medical complexities. To our knowledge, no literature evaluates how camp can positively affect emotional functioning, social functioning, self-esteem, and physical activity levels in children with SCD. Methods: Children with SCD attending a residential summer camp during 2019 were identified. Participants completed a modified version of the Pediatric Camp Outcome Measure, a validated 29-item questionnaire that evaluates self-esteem, emotional function, social function, and physical activity. Four additional questions related to SCD were included. Results: Nine campers enrolled in the study. Questionnaire results showed a total score of 113.7 (maximum score135, range 84-129), with a self-esteem subscale score of 22.1 (maximum score 25, range 20-25), an emotional subscale score of 32.1 (maximum score 40, range 25-39), a social subscale score of 38.9 (maximum score 45, range 24-45), and a physical activity subscale score of 20.6 (maximum score 25, range 19-25). All campers indicated that they would return to camp. Conclusion: Attending summer camp has a beneficial impact on emotional function, social function, self-esteem, and physical activity. Mean questionnaire scores from children with cardiac disease and cancer are similar to those of children with SCD. Increased funding should be awarded to sickle cell camps to allow for more children to have this beneficial experience.
