Management of pediatric renal trauma: Results from the American Association for Surgery and Trauma Multi-Institutional Pediatric Acute Renal Trauma Study

BACKGROUND

Pediatric renal trauma is rare and lacks sufficient population-specific data to generate evidence-based management guidelines. A nonoperative approach is preferred and has been shown to be safe. However, bleeding risk assessment and management of collecting system injury are not well understood. We introduce the Multi-institutional Pediatric Acute Renal Trauma Study (Mi-PARTS), a retrospective cohort study designed to address these questions. This article describes the demographics and contemporary management of pediatric renal trauma at Level I trauma centers in the United States.

METHODS

Retrospective data were collected at 13 participating Level I trauma centers on pediatric patients presenting with renal trauma between 2010 and 2019. Data were gathered on demographics, injury characteristics, management, and short-term outcomes. Descriptive statistics were used to report on demographics, acute management, and outcomes.

RESULTS

In total, 1,216 cases were included in this study. Of all patients, 67.2% were male, and 93.8% had a blunt injury mechanism. In addition, 29.3% had isolated renal injuries, and 65.6% were high-grade (American Association for the Surgery of Trauma Grades III-V) injuries. The mean Injury Severity Score was 20.5. Most patients were managed nonoperatively (86.4%), and 3.9% had an open surgical intervention, including 2.7% having nephrectomy. Angioembolization was performed in 0.9%. Collecting system intervention was performed in 7.9%. Overall mortality was 3.3% and was only observed in patients with multiple injuries. The rate of avoidable transfer was 28.2%.

CONCLUSION

The management and outcomes of pediatric renal trauma lack data to inform evidence-based guidelines. Nonoperative management of bleeding following renal injury is a well-established practice. Intervention for renal trauma is rare. Our findings reinforce differences from the adult population and highlights opportunities for further investigation. With data made available through Mi-PARTS, we aimed to answer pediatric specific questions, including a pediatric-specific bleeding risk nomogram, and better understanding indications for interventions for collecting system injuries.

Effect of Medicaid expansion on inflammatory bowel disease and healthcare utilization

BACKGROUND

Kentucky was among the first to adopt Medicaid expansion, resulting in reducing uninsured rates from 14.3% to 6.4%. We hypothesize that Medicaid expansion resulted in increased elective healthcare utilization and reductions in emergency treatments by patients suffering Inflammatory Bowel Disease (IBD).

METHODS

The Hospital Inpatient Discharge and Outpatient Services Database (HIDOSD) identified all encounters related to IBD from 2009 to 2020 in Kentucky. Several demographic variables were compared in pre- and post-Medicaid expansion adoption.

RESULTS

Our study analyzed 3386 pre-expansion and 24,255 post-expansion encounters for IBD patients. Results showed that hospitalization rates dropped (47.7%-8.4%), outpatient visits increased (52.3%-91.6%) and Emergency visits decreased (36.7%-11.4%). Admission following a clinical referral similarly increased with a corresponding drop in emergency room admissions. Hospital costs and lengths of stay also dropped following Medicaid expansion.

CONCLUSION

In the IBD population, Medicaid expansion improved access to preventative care, reduced hospital costs by decreasing emergency care, and increased elective care pathways.

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

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.

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

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.

Artificial intelligence evaluation of focused assessment with sonography in trauma

BACKGROUND

The focused assessment with sonography in trauma (FAST) is a widely used imaging modality to identify the location of life-threatening hemorrhage in a hemodynamically unstable trauma patient. This study evaluates the role of artificial intelligence in interpretation of the FAST examination abdominal views, as it pertains to adequacy of the view and accuracy of fluid survey positivity.

METHODS

Focused assessment with sonography for trauma examination images from 2015 to 2022, from trauma activations, were acquired from a quaternary care level 1 trauma center with more than 3,500 adult trauma evaluations, annually. Images pertaining to the right upper quadrant and left upper quadrant views were obtained and read by a surgeon or radiologist. Positivity was defined as fluid present in the hepatorenal or splenorenal fossa, while adequacy was defined by the presence of both the liver and kidney or the spleen and kidney for the right upper quadrant or left upper quadrant views, respectively. Four convolutional neural network architecture models (DenseNet121, InceptionV3, ResNet50, Vgg11bn) were evaluated.

RESULTS

A total of 6,608 images, representing 109 cases were included for analysis within the "adequate" and "positive" data sets. The models relayed 88.7% accuracy, 83.3% sensitivity, and 93.6% specificity for the adequate test cohort, while the positive cohort conferred 98.0% accuracy, 89.6% sensitivity, and 100.0% specificity against similar models. Augmentation improved the accuracy and sensitivity of the positive models to 95.1% accurate and 94.0% sensitive. DenseNet121 demonstrated the best accuracy across tasks.

CONCLUSION

Artificial intelligence can detect positivity and adequacy of FAST examinations with 94% and 97% accuracy, aiding in the standardization of care delivery with minimal expert clinician input. Artificial intelligence is a feasible modality to improve patient care imaging interpretation accuracy and should be pursued as a point-of-care clinical decision-making tool.

Standardization and Visualization of the Surgical Time-Out

INTRODUCTION

The time-out (TO) can prevent adverse events but is subject to TO engagement. We hypothesize transforming the TO to an auditable, active process will improve compliance and engagement.

METHODS

The passive nature of the current TO was identified as a potential safety issue on staff patient safety culture surveys. Subsequently, the Time Out Engagement and Standardization quality improvement initiative was developed and included a whiteboard checklist to be used in the operating room. As a baseline, 11 TOs were audited concerning engagement and content. Key stakeholders were engaged to determine potential interventions. A TO consisting of 15 elements using a TO whiteboard checklist with role-specific objectives was developed. Plan, Do, Study, Act cycles commenced. After implementation, 17 TOs were audited based on engagement and content.

RESULTS

Before intervention, engagement varied with nurse participating in 100% compared with anesthesia provider or surgeon participating in 18%. No TO included all 15 elements and only 13% of elements included in all TOs. After implementation of Time Out Engagement and Standardization, anesthesia and surgeon who participated increased to 100% and 76.5%, respectively (P < 0.0001, P = 0.006). The 15 standardized elements of the TO were discussed in 90% of cases. Overall, preintervention 88 elements (57.1%) were completed across all TOs, while postintervention 243 elements (98.8%) were completed (P < 0.001).

CONCLUSIONS

We identified a need for increased engagement of the TO based on staff concerns, which were verified through auditing. Implementation of a team-driven intervention and 3 rapid Plan, Do, Study, Act cycles led to measurable improvement of the surgical TO.

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

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.

Improving physician documentation for malnutrition: A sustainable quality improvement initiative

This study compares documentation and reimbursement rates before and after provider education in nutritional status documentation. Our study aimed to evaluate accurate documentation of nutrition status between registered dietitian nutritionists and licensed independent practitioners before and after the implementation of a dietitian-led Nutrition-Focused Physical Exam intervention at an academic medical center in the southeastern US. ICD-10 codes identified patients from 10/1/2016-1/31/2018 with malnutrition. The percentage of patients with an appropriate diagnosis of malnutrition and reimbursement outcomes attributed to malnutrition documentation were calculated up to 24 months post-intervention. 528 patients were analyzed. Pre-intervention, 8.64% of patients had accurate documentation compared to 46.3% post-intervention. Post-intervention, 68 encounters coded for malnutrition resulted in an estimated $571,281 of additional reimbursement, sustained at 6, 12, 18, and 24 months. A multidisciplinary intervention improved physician documentation accuracy of malnutrition status and increased reimbursement rates.

Pediatric Rhabdomyosarcomas of the Genitourinary Tract

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.

Procedure-Based Telehealth Utilization in General Surgery

The authors hypothesize that standardized telehealth (TH) scheduling processes will improve TH utilization without increasing adverse events. Fifty visits preimplementation and 67 visits postimplementation were audited from June 2021 to January 2022. Both leadership and frontline stakeholders were engaged to identify current workflows and potential interventions targeting outpatient elective procedures. Process mapping outlined current TH scheduling workflows. Outcomes related to TH completion, cost, and TH scheduling were collected after implementation. Preimplementation TH scheduling rate was 32%. The intervention required TH postoperative appointments to be scheduled in clinic at the time of surgery scheduling with TH being the default postsurgical appointment for a standardized list of eligible procedures. Following implementation, 95% of patients undergoing eligible procedures had TH follow-up. This provided improved access to surgical follow-up care, by reducing travel needs to the Veterans Affairs facility. Secondarily, this intervention increased clinic appointment availability and resulted in possible increased revenue for billable visits. Standardizing TH scheduling based on the procedure improves the utilization of TH resulting in improved clinic efficiency and increased revenue, without increasing adverse events.

Evaluation of the learning curve for laparoscopic pyloromyotomy

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.

Surgical Site Infections in Colorectal Resections: What is the Cost?

INTRODUCTION

Although surgical site infections (SSIs) associated with colectomy are tracked by the National Healthcare Safety Network/Center for Disease Control, untracked codes, mainly related to patients undergoing proctectomy, are not. These untracked codes are performed less often yet they may be at a greater risk of SSI due to their greater complexity. Determining the impact and predictors of SSI are critical in the development of quality improvement initiatives.

METHODS

Following an institutional review board approval, National Surgery Quality Improvement Program, institutional National Surgery Quality Improvement Program, and financial databases were queried for tracked colorectal resections and untracked colorectal resections (UCR). National data were obtained for January 2019-December 2019, and local procedures were identified between January 2013 and December 2019. Data were analyzed for preoperative SSI predictors, operative characteristics, outcomes, and 30-day postdischarge costs (30dPDC).

RESULTS

Nationally, 71,705 colorectal resections were identified, and institutionally, 2233 patients were identified. UCR accounted for 7.9% nationally and 11.8% of all colorectal resections institutionally. Tracked colorectal resection patients had a higher incidence of SSI predictors including sepsis, hypoalbuminemia, coagulopathy, hypertension, and American Society of Anesthesiologists class. UCR patients had a higher rate of SSIs [12.9% (P < 0.001), 15.2% (P = 0.064)], readmission, and unplanned return to the operating room. Index hospitalization and 30dPDC were significantly higher in patients experiencing an SSI.

CONCLUSIONS

SSI was associated with nearly a two-fold increase in index hospitalization costs and six-fold in 30dPDC. These data suggest opportunities to improve hospitalization costs and outcomes for patients undergoing UCR through protocols for SSI reduction and preventing readmissions.

Opioid Use After Colorectal Resection: Identifying Preoperative Risk Factors for Postoperative Use

INTRODUCTION

Appropriate prescribing practices are imperative to ensure adequate pain control, without excess opioid dispensing across colorectal patients.

METHODS

National Surgical Quality Improvement Program, Kentucky All Scheduled Prescription Electronic Reporting, and patient charts were queried to complete a retrospective study of elective colorectal resections, performed by a fellowship-trained colorectal surgeon, from January 2013 to December 2020. Opioid use at 14 d and 30 d posthospital discharge converted into morphine milligram equivalents (MMEs) were analyzed and compared across preadmission and inpatient factors.

RESULTS

One thousand four hundred twenty seven colorectal surgeries including 56.1% (N = 800) partial colectomy, 24.1% (N = 344) low anterior resection, 8.3% (N = 119) abdominoperineal resection, 8.4% (N = 121) sub/total colectomy, and 3.0% (N = 43) total proctocolectomy. Abdominoperineal resection and sub/total colectomy patients had higher 30-day postdischarge MMEs (P < 0.001, P = 0.041). An operative approach did not affect postdischarge MMEs (P = 0.440). Trans abdominal plane blocks do not predict postdischarge MMEs (0.616). Epidural usage provides a 15% increase in postdischarge MMEs (P = 0.020). Age (P < 0.001), smoking (P < 0.001), chronic obstructive pulmonary disease (P = 0.006, < 0.001), dyspnea (P = 0.001, < 0.001), albumin < 3.5 (P = 0.085, 0.010), disseminated cancer (P = 0.018, 0.001), and preadmission MMEs (P < 0.001) predict elevated 14-day and 30-day postdischarge MMEs.

CONCLUSIONS

We conclude that perioperative analgesic procedures, as enhanced recovery pathway suggests, are neither predictive nor protective of postoperative discharge MMEs in colorectal surgery. Provider should account for preoperative risk factors when prescribing discharge opioid medications. Furthermore, providers should identify appropriate adjunct procedures to improve discharge opioid prescription stewardship.

Completion Lymph Node Dissection for Melanoma Before and After the Multicenter Selective Lymphadenectomy Trial-II in the United States

BACKGROUND

The Multicenter Selective Lymphadenectomy Trial-II (MSLT-II) revealed completion lymph node dissection (CLND) after positive sentinel lymph node biopsy (SLNB) did not improve melanoma-specific survival compared with surveillance. Given these findings and the morbidity associated with CLND, this study investigated trends in rates and predictors of CLND after MSLT-II.

METHODS

Analysis of the National Cancer Database was performed for all patients aged ≥18 years with melanoma and a positive SLNB for 2012-2019. Rates of CLND before and after publication of MSLT-II were identified and logistic regression used to identify factors associated with CLND.

RESULTS

Patients undergoing CLND declined from 55.9% pre-MSLT-II (n = 9725) to 19.5% post-MSLT-II (n = 9419) (odds ratio [OR] 0.32, 95% confidence interval [CI] 0.29-0.35). CLND was less likely in females (OR 0.83; 95% CI 0.78-0.89), older patients (vs. 18-39 yr; 40-64 yr OR 0.80, 95% CI 0.65-0.98; 65-79 yr OR 0.67, 95% CI 0.53-0.84; >80 yr OR 0.38, 95% CI 0.30-0.49), sicker patients (Deyo category ≥2 OR 0.85, 95% CI 0.73-0.99), thinner primary lesions (vs. 0.01-0.79 mm; 1.01-4.00 mm OR 1.16, 95% CI 1.01-1.33; ≥4.01 mm OR 1.31, 95% CI 1.08-1.59), patients from metro areas (Rural OR 1.31, 95% CI 1.00-1.70; Urban OR 1.15, 95% CI 1.03-1.29), and those treated at lower-volume centers (vs. lowest-volume; highest-volume OR 1.31, 95% CI 1.14-1.50; high-volume OR 1.40, 95% CI 1.24-1.57).

CONCLUSIONS

MSLT-II has impacted clinical care; however, male gender, thicker lesions, rural/urban residence, younger age, fewer comorbidities, and treatment at higher-volume centers confer a greater likelihood of undergoing CLND. Further investigations should focus on whether these populations benefit from more aggressive surgical care.

Pediatric Neuroendocrine Neoplasms: Rare Malignancies with Incredible Variability

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.

Management of Double Carotid Blow Out with Definitive Repair After Temporizing Stent Graft Placement

Carotid blowout syndrome is a life-threatening complication for patients with head and neck cancer. Temporizing stent graft procedures improve short-term survival and can be the definitive treatment for various reasons, including a poor oncologic prognosis, unsuitability for definitive reconstruction, or a lack of operative options. A second carotid blowout will often be fatal. Preventing such events requires multidisciplinary strategic planning because of a hostile reoperative field. We have described a case of a 44-year-old man with a history of laryngeal cancer who had experienced a carotid blowout. Treated with a stent graft, the patient had experienced a second event 6 weeks later. Treatment involved excision and suture ligation with rotational muscle flap coverage.

Cat-scratch disease simulating malignant lymphoma

A six-year-old girl with induration, swelling and discoloration of the lower eyelid, a temporal mass, preauricular adenopathy and enlarged parotid gland, underwent biopsy, She was initially diagnosed as having a malignant disorder of histiocytic origin. All lesions resolved without therapy. Further evaluation revealed that the child had oculoglandular cat-scratch disease. Cat-scratch disease should be added to the list of nonmalignant disorders which may simulate a malignant neoplasm in its clinical and histologic appearance. Recognition of this fact is important in order to avoid erroneous diagnosis, unnecessary procedures and hazardous therapy.

67Ga scintigraphy in granulocytic sarcoma

Several granulocytic sarcomas (chloromas) developed in a patient with acute myelogenous leukemia while in hematologic remission. A positive diagnosis of the symptomatic lesion was made by means of open biopsy examination. The other lesions, which were unsuspected, were detected with a 67Ga-citrate scan. Subsequent 67Ga-citrate scans indicated a favorable response to treatment. The incidence and significance of silent granulocytic sarcomas in patients in hematologic remission is not known. Documentation of such lesions might prove valuable for diagnosing extramedullary relapse or for delivering intensive local therapy.
