    Compliance With Skeletal Surveys for Child Abuse in General Hospitals: A Statewide Quality Improvement Process
    (ARRS, 2019-05) Wanner, Matthew R.; Marine, Megan B.; Hibbard, Roberta A.; Ouyang, Fangqian; Jennings, S. Gregory; Shea, Lindsey; Karmazyn, Boaz; Radiology and Imaging Sciences, School of Medicine
    OBJECTIVE. The purpose of this study is to perform a statewide quality improvement process to improve compliance with the American College of Radiology (ACR) guidelines in performing skeletal surveys for suspected child abuse. SUBJECTS AND METHODS. We prospectively identified all outside hospital skeletal surveys for suspected child abuse in children younger than 3 years referred to our tertiary children's hospital in 2016–2017. We included a 3-month baseline and 21-month intervention period. The quality improvement process was based on sending educational material to all ACR member radiologists in the state and making telephone calls to radiology technologist team leaders whenever the surveys were not compliant, followed by e-mails with guidance on performing skeletal surveys. We documented the views obtained and compared them with the ACR guidelines. The percentage of compliance with each individual view was assessed with the chi-square test. The total number of compliant views per survey was evaluated with ANOVA. RESULTS. Two hundred twenty-seven patients (105 female) with a mean age of 0.8 year (SD, 0.67 year; range, 0.01–3 years) were evaluated. These 227 surveys (baseline, n = 27; postintervention, n = 200) were performed at 69 different outside hospitals. Compliance significantly (p = 0.006) improved from 25.9% (7/27) during baseline to 54.0% (108/200) after intervention. There was a nonsignificant trend of improved compliance between the first (51.9%; 41/79) and last 7-month (62.3%; 33/53) periods of intervention. Among individual views, only rib oblique views showed significantly (p = 0.02) improved compliance after the intervention, from 51.9% (14/27) to 73.5% (147/200). CONCLUSION. The compliance rate with ACR guidelines for skeletal surveys in suspected child abuse at outside general hospitals significantly increased after implementation of a quality improvement process.

    Just in Time Radiology Decision Support Using Real-time Data Feeds
    (SpringerLink, 2020-02) Burns, John L.; Hasting, Dan; Gichoya, Judy W.; McKibben, Ben, III.; Shea, Lindsey; Frank, Mark; Radiology and Imaging Sciences, School of Medicine
    Ready access to relevant real-time information in medical imaging offers several potential benefits. Knowing both when important information will be available and that important information is available can facilitate optimization of workflow and management of time. Unexpected findings, as well as deficiencies in reporting and documentation, can be immediately managed. Herein, we present our experience developing and implementing a real-time web-centric dashboard system for radiologists, clinicians, and support staff. The dashboards are driven by multi-sourced HL7 message streams that are monitored, analyzed, aggregated, and transformed into multiple real-time displays to improve operations within our department. We call this framework Pipeline. Ruby on Rails, JavaScript, HTML, and SQL serve as the foundations of the Pipeline application. HL7 messages are processed in real-time by a Mirth interface engine which posts exam data into SQL. Users utilize web browsers to visit the Ruby on Rails-based dashboards on any device connected to our hospital network. The dashboards will automatically refresh every 30 seconds using JavaScript. The Pipeline application has been well received by clinicians and radiologists.

    Superior vena cava syndrome in a patient with locally advanced lung cancer with good response to definitive chemoradiation: a case report
    (Biomed Central, 2018-10-20) Hinton, Jason; Cerra-Franco, Alberto; Shiue, Kevin; Shea, Lindsey; Aaron, Vasantha; Billows, Geoffrey; Al-Hader, Ahmad; Lautenschlaeger, Tim; Radiation Oncology, School of Medicine
    BACKGROUND: The incidence of superior vena cava syndrome within the United States is roughly 15,000 cases per year. Superior vena cava syndrome is a potentially life-threatening medical condition; however, superior vena cava syndrome is not fatal in the majority of cases. Superior vena cava syndrome encompasses a collection of signs and symptoms resulting from obstruction of the superior vena cava, including swelling of the upper body of the head, neck, arms, and/or breast. It is also associated with cyanosis, plethora, and distended subcutaneous vessels. Lung cancer, including both non-small cell lung cancer and small cell lung cancer, is the most common extrinsic cause of superior vena cava syndrome. Intrinsic disruption of superior vena cava flow can also precipitate superior vena cava syndrome. This case report describes an unusual presentation and potential etiology of superior vena cava syndrome. CASE PRESENTATION: Our patient was a 51-year-old black woman with locally advanced, stage IIIB non-small cell lung cancer who had no clinical symptoms of superior vena cava syndrome at the time of diagnosis. However, she did have radiographic evidence of superior vena cava stenosis caused by extrinsic compression from her large right hilar primary tumor. She was treated with definitive chemoradiation, receiving 60 Gy of external beam radiation therapy given concurrently with chemotherapy. Three months after completion of radiotherapy, she developed signs of superior vena cava syndrome, including breast and supraclavicular swelling. She had a chest computed tomography scan showing over 50% reduction in the size of a right hilar mass; however, she had continued radiographic stenosis of the superior vena cava. The distribution of stenosis appeared to be inferior to the caudal extent of pretreatment tumor volume. She had no other radiographic indications for superior vena cava syndrome. CONCLUSIONS: Generally, superior vena cava syndrome is the result of extrinsic compression of the superior vena cava by tumor. Our patient's case represents the development of superior vena cava syndrome after an excellent response of tumor with near-complete tumor response. We suspect chemoradiation therapy as a potential etiology for the precipitation of the superior vena cava syndrome, which is currently not well reported in the medical literature.
