Vascular Anomalies Care in the United States: A Cross-Sectional National Survey.

OBJECTIVE: To characterize the current distribution, composition, and practice patterns of multidisciplinary vascular anomalies (VAs) teams in the US. STUDY DESIGN: This is a cross-sectional survey of children's hospitals in the US offering VAs care. We approached 142 children's hospitals that provided care for VAs via email. The survey evaluated VA clinic location, medical staffing, research participation, and treatments offered. The survey was administered between October 2021 and July 2022. RESULTS: Participants from 95 eligible hospitals responded to the survey (response rate = 67%). Large areas of the Midwest and Northwest US had no available multidisciplinary VA teams or clinics. Most respondents worked at academic centers (89%), with 66% at a freestanding children's hospital, and 56% reported having a multidisciplinary clinic. Most common physician participants in clinic included hematology-oncology (91%), interventional radiology (87%), dermatology (85%), plastic surgery (81%), and otolaryngology (74%). Only 38% of programs included medical geneticists. Smaller hospitals had fewer medical and ancillary staff and offered fewer therapeutic options. Research was available at most larger institutions (69%) but less commonly at smaller hospitals (34%). CONCLUSIONS: Major portions of the US lack multidisciplinary VA care. Furthermore, VA programs vary in composition and geneticists are absent from the majority of programs. These findings should inform efforts to address disparate access and develop standards of care for multidisciplinary VA care in the US.

Early Post-Therapy Prescription Drug Usage among Childhood and Adolescent Cancer Survivors.

OBJECTIVE: To describe the patterns of prescription drug use among child and adolescent survivors of cancer in the early post-therapy period compared with matched peers without a cancer history. STUDY DESIGN: Using the MarketScan commercial insurance claims database, we performed a retrospective cohort study identifying survivors of pediatric (0-21 years of age at diagnosis) leukemia, lymphoma, central nervous system, bone, or gonadal cancers who completed therapy from 2000 to 2011 and remained insured for 3 years post-therapy. Prescription fills during the first 3 years post-therapy were examined, categorized by drug class, and compared with age-, sex-, and region-matched individuals without cancer. RESULTS: We identified 1414 survivors and 14 007 comparators. Compared with those without cancer, survivors had 1.5-4.5 times greater risk for filling opioids. Survivors of leukemia, lymphoma, central nervous system, and bone cancers had 2-5 times the risk for antidepressant and 3-7 times the risk for anxiolytic use. Survivors of leukemia, lymphoma, and bone tumors had 3-13 times the risk for angiotensin-converting enzyme inhibitors by the third year post-therapy. CONCLUSION: Compared with peers without cancer, survivors of childhood cancer have greater rates of prescription use across many drug classes, suggesting greater medical morbidity. Survivors were more likely to use opioid, psychoactive, hormone, and cardiovascular medications. All general pediatricians and subspecialists should be aware of potentially emerging morbidities during the early post-therapy period to guide risk-based surveillance and survivorship care.
