Reducing Sedation for Pediatric Thoracic CT Imaging Using Volumetric Target-mode EKG Gating.

Introduction: Many children require sedation for imaging. We aimed to reduce sedation for thoracic (chest and cardiac) computed tomography (CT) scans in children 0-4 years old from 65% to 20% by December 2018 and to sustain.

Methods: We counted baseline, intervention, and a follow-up period thoracic CT scans performed with sedation in children 0-4 years old.

Factors that Affect Patient Wait Times at a Free Clinic.

Free clinics may present long wait times. A retrospective chart review was conducted at a free clinic to understand contributing factors. Three wait times (total visit time, lobby wait time, and triage time) were analyzed across 349 patients.

COVID-19 Vaccination Rates and Vaccine Hesitancy Among Spanish-Speaking Free Clinic Patients.

We sought to assess COVID-19 vaccination rates, as well as attitudes and beliefs towards the vaccine, of patients in a Spanish-speaking student-run free clinic in Columbus, Ohio. A cross-sectional study was performed. Surveys were distributed to all individuals over 18 years who presented to La Clínica Latina between July, 2022 and September, 2022.

Workflow Interruptions and Effect on Study Interpretation Efficiency.

Background: Interruptions have been shown to adversely impact efficiency, accuracy, and patient safety.

Objective: To analyze the frequency and types of interruptions and effect on report interpretation efficiency.

Materials And Methods: A business process improvement team was consulted to make detailed recordings of the activities of the radiologists.

Mechanisms and management considerations of parent-chosen feeding approaches to infants with swallowing difficulties: an observational study.

Videofluoroscopy swallow studies (VFSS) and high-resolution manometry (HRM) methods complement to ascertain mechanisms of infant feeding difficulties. We hypothesized that: (a) an integrated approach (study: parent-preferred feeding therapy based on VFSS and HRM) is superior to the standard-of-care (control: provider-prescribed feeding therapy based on VFSS), and (b) motility characteristics are distinct in infants with penetration or aspiration defined as penetration-aspiration scale (PAS) score ≥ 2. Feeding therapies were nipple flow, fluid thickness, or no modification.

Advanced imaging use and payment trends in a large pediatric accountable care organization.

Background: Pediatric imaging use and payment trends in accountable care organizations (ACOs) are seldom studied but are important for health policy decisions and resource allocation.

Objective: To evaluate patterns of advanced imaging use and associated payments over a 7-year period at a large ACO in the USA serving a Medicaid population.

Materials And Methods: We reviewed paid claims data from 2011 through 2017 from an ACO, analyzing the MRI, CT and US use trends and payments from emergency department (ED) and outpatient encounters.

Somatic mosaicism correlates with clinical findings in epilepsy brain tissue.

Objective: Many genetic studies of intractable epilepsy in pediatric patients primarily focus on inherited, constitutional genetic deficiencies identified in patient blood. Recently, studies have revealed somatic mosaicism associated with epilepsy in which genetic variants are present only in a subset of brain cells. We hypothesize that tissue-specific, somatic mosaicism represents an important genetic etiology in epilepsy and aim to discover somatic alterations in epilepsy-affected brain tissue.

Implementation of an Innovative Tablet-based Curriculum for Radiology Resident Education.

Rationale And Objectives: The aim of this study was to prospectively examine the impact of a tablet-based curriculum on the radiology resident educational experience.

Materials And Methods: A comprehensive tablet-based curriculum was developed by creating subspecialty modules with appropriate content level for each required rotation at our diagnostic radiology residency program. Daily assignments included key learning points, readings, and reference presentation slides, covering all objectives published by the ABR Core Exam Study Guide.

Synchronous Central Nervous System Atypical Teratoid/Rhabdoid Tumor and Malignant Rhabdoid Tumor of the Kidney: Case Report of a Long-Term Survivor and Review of the Literature.

Background: Atypical teratoid/rhabdoid tumor (AT/RT) of the central nervous system (CNS) with synchronous or metachronous extra-CNS disease is a rare childhood malignancy with a dismal prognosis.

Case Description: We report a 7-week-old female with metastatic AT/RT and synchronous malignant rhabdoid tumor of the kidney who received an intensive multimodal approach combining surgical resection, intrathecal chemotherapy, and high-dose chemotherapy with autologous peripheral blood stem cell transplant (PBSCT). She is currently 24 months old without any evidence of disease.

Cost-benefit analysis of establishing an inferior vena cava filter clinic.

Purpose: Adverse events associated with retrievable inferior vena cava filters (IVCFs) have generated an increased interest in improving IVCF retrieval rates to improve patient safety and quality care. This study aims to demonstrate the cost-benefit of implementing an IVCF clinic to improve patient care in an institution in the United States.

Methods: An IVCF clinic was established at a single institution in September 2012 and for ten months referring physicians were contacted to facilitate retrieval when appropriate.

Design-of-Experiments Approach to Improving Inferior Vena Cava Filter Retrieval Rates.

Purpose: The association of retrievable inferior vena cava filters (IVCFs) with adverse events has led to increased interest in prompt retrieval, particularly in younger patients given the progressive nature of these complications over time. This study takes a design-of-experiments (DOE) approach to investigate methods to best improve filter retrieval rates, with a particular focus on younger (<60 years) patients.

Methods: A DOE approach was executed in which combinations of variables were tested to best improve retrieval rates.
