  • Language Barriers in Appendicitis: What is the Cost?

    by Brittany E. Levy, Jennifer T. Castle, Lekha P. Devara, Elena C. Manauis, Hannah G. McDonald, Wesley A. Stephens, Daniel L. Davenport, Eric J. Rellinger, David J. Worhunsky

    Background: In clinical scenarios, pediatricians prefer patient history over imaging to diagnose pediatric appendicitis because they wish to limit their patients’ exposure to radiation. Language barriers between providers and patients with limited English proficiency may increase adverse outcomes, require more imaging studies, and lead to higher costs in cases of pediatric appendicitis. Methods: We queried the pediatric-National Surgical Quality Improvement Project database for patients under age 16 who received appendectomies from 2011-2021 at a single institution. Patients were propensity matched based on age, gender, Hispanic ethnicity, and insurance status. Medical records and hospital billing were merged to obtain primary language, initial hospitalization cost, diagnostic work up modalities, and operative findings. Patients identifying English as their primary language were termed English proficient (EP). Those selecting an alternate primary language made up the limited English proficiency (LEP) cohort. Health care utilization outcomes including cost, length of stay (LOS), and imaging usage were compared across cohorts. Results: 400 patients were matched for analysis: 92 were EP and 109 LEP. When compared with the EP cohort, patients with LEP had higher rates of diagnostic imaging, longer median LOS, and higher median hospital costs. Imaging costs were also higher in patients with LEP. We also observed higher rates of negative appendectomy in the EP patients, compared to the LEP cohort. Discussion: In patients with LEP, language diversity creates communication barriers resulting in higher health care utilization. Significant variations in the cost of care, efficiency of care, and clinical outcomes related to language diversity should be reduced to ensure equitable health care delivery to all pediatric surgical patients.

  • Impact of the Affordable Care Act on Providing Equitable Healthcare Access for IBD in the Kentucky Appalachian Region

    by Jennifer T. Castle, Brittany E. Levy, Anthony A. Mangino, Hannah G. McDonald, Erin D.O. McAtee, Jitesh A. Patel, B. Mark Evers, Avinash S. Bhakta

    BACKGROUND: Medicaid expansion improved insurance coverage for patients with chronic conditions and low income. The effect of Medicaid expansion on patients with IBD from high-poverty communities is unknown. OBJECTIVE: This study aimed to evaluate the impact of Medicaid expansion in Kentucky on care for patients with IBD from the Eastern Kentucky Appalachian community, a historically impoverished area. DESIGN: This study was a retrospective, descriptive, and ecological study. SETTINGS: This study was conducted in Kentucky using the Hospital Inpatient Discharge and Outpatient Services Database. PATIENTS: All encounters for IBD care for 2009–2020 for patients from the Eastern Kentucky Appalachian region were included. MAIN OUTCOME MEASURES: The primary outcomes measured were proportions of inpatient and emergency encounters, total hospital charge, and hospital length of stay. RESULTS: Eight hundred twenty-five preexpansion and 5726 postexpansion encounters were identified. Postexpansion demonstrated decreases in the uninsured (9.2%–1.0%; p < 0.001), inpatient encounters (42.7%–8.1%; p < 0.001), emergency admissions (36.7%–12.3%; p < 0.001), admissions from the emergency department (8.0%–0.2%; p < 0.001), median total hospital charge ($7080–$3260; p < 0.001), and median total hospital length of stay (4–3 days; p < 0.001). Similarly, postexpansion demonstrated increases in Medicaid coverage (18.8%–27.7%; p < 0.001), outpatient encounters (57.3%–91.9%; p < 0.001), elective admissions (46.9%–76.2%; p < 0.001), admissions from the clinic (78.4%–90.2%; p < 0.001), and discharges to home (43.8%–88.2%; p < 0.001). LIMITATIONS: This study is subject to the limitations inherent in being retrospective and using a partially de-identified database. CONCLUSION: This study is the first to demonstrate the changes in trends in care after Medicaid expansion for patients with IBD in the Commonwealth of Kentucky, especially Appalachian Kentucky, showing significantly increased outpatient care utilization, reduced emergency department encounters, and decreased length of stays.

    Pediatric Rhabdomyosarcomas of the Genitourinary Tract

    by Jennifer T. Castle, Brittany E. Levy, Derek B. Allison, David A. Rodeberg, Eric J. Rellinger

    Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in the pediatric and adolescent population, with 350 new cases diagnosed each year. While they can develop anywhere in the body, the genitourinary tract is the second most common primary location for an RMS to develop. Overall survival has improved through the increased use of protocols and multidisciplinary approaches. However, the guidelines for management continue to change as systemic and radiation therapeutics advance. Given the relative rarity of this disease compared to other non-solid childhood malignancies, healthcare providers not directly managing RMS may not be familiar with their presentation and updated management. This review aims to provide foundational knowledge of the management of RMSs with an emphasis on specific management paradigms for those arising from the genitourinary tract. The genitourinary tract is the second most common location for an RMS to develop but varies greatly in symptomology and survival depending on the organ of origin. As the clinical understanding of these tumors advances, treatment paradigms have evolved. Herein, we describe the breadth of presentations for genitourinary RMSs with diagnostic and treatment management considerations, incorporating the most recently available guidelines and societal consensus recommendations.


  • Injury Pattern and Outcomes Following All-Terrain Vehicle Accidents in Kentucky Children: A Retrospective Study

    by Brittany E. Levy, McKell Quattrone, Jennifer T Castle, Andrea N. Doud, John M. Draus, David J. Worhunsky

    Purpose: All-terrain vehicles (ATVs) pose a significant risk for morbidity and mortality amongst children. We hypothesize that current vague legislation regarding helmet use impacts injury patterns and outcomes in pediatric ATV accidents. Methods: The institutional trauma registry was queried for pediatric patients involved in ATV accidents from 2006 to 2019. Patient demographics and helmet wearing status were identified in addition to patient outcomes, such as injury pattern, injury severity score, mortality, length of stay, and discharge disposition. These elements were analyzed for statistical significance. Results: 720 patients presented during the study period, which were predominantly male (71%, n = 511) and less than 16 years old (76%, n = 543). Most patients were not wearing a helmet (82%, n = 589) at time of injury. Notably, there were 7 fatalities. A lack of helmet use is positively associated with head injury (42% vs 23%, P < .01), intracranial hemorrhage (15% vs 7%, P = .03), and associated with lower Glasgow Coma Scale (13.9 vs 14.4, P < .01). Children 16 years and older were least likely to wear a helmet and most likely to incur injuries. Patients over 16 years had longer lengths of stay, higher mortality, and higher need for rehabilitation. Conclusion: Not wearing a helmet is directly correlated with injury severity and concerning rates of head injury. Children 16 years and older are at greatest risk for injury, but younger children are still at risk. Stricter state laws regarding helmet use are necessary to reduce pediatric ATV-related injury burden. Level of Evidence: level III retrospective comparative study


  • Evaluation of the learning curve for laparoscopic pyloromyotomy

    by Brittany E. Levy, Mia MacDonald, Nicholas Bontrager, Jennifer T. Castle, John M. Draus, David J. Worhunsky

    Background Laparoscopic pyloromyotomy is the preferred surgical management of hypertrophic pyloric stenosis at most centers. We aimed to analyze the learning curve for laparoscopic pyloromyotomy using the experience of five fellowship-trained pediatric surgeons. Methods A retrospective review of consecutive patients undergoing laparoscopic pyloromyotomy was performed. All cases were performed with general surgery residents. Cumulative sum (CUSUM) analysis for operating time was performed for up to the first 150 consecutive cases for individual surgeons. Outcomes were compared to identify different phases of the learning curve for operative competency. Results A total of 414 patients were included in the analysis as not all surgeons had reached 150 cases at time of analysis. The mean operating time was 29.2 min for all cases across the 5 surgeons. CUSUM analysis for mean operating time revealed three phases of learning: Learning Phase (cases 1-16), Plateau Phase (cases 17-87), and a Proficiency Phase (cases 88-150). The mean operating time during the three phases was 34.1, 29.0, and 28.3 min, respectively (P = 0.005). There were no differences in complications, reoperations, length of stay, or readmissions across the three phases. Conclusion Three distinct phases of learning for laparoscopic pyloromyotomy were identified with no differences in outcomes across the phases. The operating time differed only for the Learning Phase, suggesting that some degree of proficiency occurs after 16 cases. Graphical abstract

    Pediatric Neuroendocrine Neoplasms: Rare Malignancies with Incredible Variability

    by Jennifer T. Castle, Brittany E. Levy, Aman Chauhan

    Neuroendocrine neoplasms (NENs) encompass a variety of neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs) which can arise anywhere in the body. While relatively rare in the pediatric population, the incidence of NENs has increased in the past few decades. These neoplasms can be devastating if not diagnosed and treated early, however, symptoms are variable and can be indolent for many years. There is a reported median of 10 years from the appearance of the first symptoms to time of diagnosis. Considering some of these neoplasms have a mortality rate as high as 90%, it is crucial healthcare providers are aware of NENs and remain vigilant. With better provider education and easily accessible resources for information about these neoplasms, awareness can be improved leading to earlier disease recognition and diagnosis. This manuscript aims to provide an overview of both the most common NENs as well as the rarer NENs with high lethality in the pediatric population. This review provides up to date evidence and recommendations, encompassing recent changes in classification and advances in treatment modalities, including recently completed and ongoing clinical trials.


  • Reducing Emergency Department Length of Stay in Critically Injured Pediatric Trauma Patients: A Quality Improvement Initiative

    by Jennifer T. Castle, Brittany E. Levy, Wesley S. Wilt, John M. Draus

    Background: Efficient transfer of adult trauma patients to the intensive care unit (ICU) is associated with decreased emergency department (ED) length of stay (ED LOS) and improved patient outcomes. While well studied in adults, quality improvement (QI) initiatives focused on the rapid transfer of pediatric trauma patients are lacking. We report the effect of institutional system changes directed at expediting the transfer of pediatric trauma patients to the pediatric ICU (PICU). Methods: This initiative commenced in 2013. Preliminary data regarding ED LOS for pediatric trauma patients were collected from January through December 2012 as the pre-implementation cohort. Using the plan-do-study-act (PDSA) framework of QI, the first PDSA cycle was implemented in January 2013. In subsequent PDSA cycles, we implemented the mandatory attendance of the PICU charge nurse and the PICU attending physician to all highest-level pediatric trauma activations. Throughout, ED LOS was collected and mapped on a run chart. ED LOS and variance were compared between all cycles of implementation. Results: One hundred and fifty-one pediatric patients arrived or were upgraded to the highest-level pediatric trauma activation and admitted to the PICU from 2012 through 2019. We observed a decrease in median ED LOS of 105 minutes between the pre- and post-implementation groups. With each PDSA cycle, we observed a decrease in median ED LOS and variation. Conclusion: The inclusion of the PICU charge nurse and attending physician at highest-level pediatric trauma activations facilitated more rapid access to the PICU with decreased ED LOS.
