To update, clarify, and extend IDEAL concepts recommendations.New surgical procedures, devices, other complex interventions need robust evaluation for safety, efficacy, effectiveness. Unlike new medicines, there is no internationally agreed pathway generating analyzing data throughout the life cycle of innovations. The Framework Recommendations were designed to provide this they have been used increasingly since their introduction in 2009. Based on a Delphi survey, expert workshop major...

Abstract Background Evaluation of new surgical procedures is a complex process challenged by evolution technique, operator learning curves, the possibility variable procedural quality, and strong treatment preferences among patients clinicians. Preliminary studies that address these issues are needed to prepare for successful randomized trial. The IDEAL (Idea, Development, Exploration, Assessment Long-term follow-up) Framework Recommendations provide an integrated step-by-step evaluation...

BACKGROUND Computed tomography is the criterion standard for diagnosing intra-abdominal injury (IAI) but expensive and risks radiation exposure. The Pediatric Emergency Care Applied Research Network (PECARN) model identifies children at low risk of IAI requiring intervention (IAI-I) in whom computed may be omitted does not provide an individualized assessment to positively predict IAI-I. We sought apply machine learning algorithms PECARN blunt abdominal trauma (BAT) data set experimentally...

Background: Cervical spine injuries (CSI) have the potential to cause severe morbidity in children. Multiple imaging studies are used during evaluation of CSIs but come at a cost, both financially and radiation exposure. To reduce resource utilization exposure, we implemented Pediatric Spine Clearance Working Group (PCSCWG) standardized protocol (SP) for evaluating Methods: Children below 18 years old presenting with concern CSI level 1 pediatric trauma center were reviewed before (July 2015...

Appendicitis is the most common condition requiring emergency surgery in children. We implemented a standardized protocol (SP) for treating children with appendicitis to provide more uniform care and reduce resource utilization.All patients younger than 21 years were managed SP beginning January 2017. compared data from 22 months before after implementation. The primary outcomes included length of stay (LOS), antibiotic days, discharge on intravenous antibiotics, utilization peripherally...

A 2 month old, full term, previously healthy male, with known COVID-19 infection 3 weeks prior to arrival presented the Emergency Department (ED) complaints of 5–6 episodes non-bilious and non-bloody emesis. According child's parents, emesis was mostly associated feeding. His parents endorsed that patient had one episode diarrhea maroon in color appeared different than typical stools. Abdominal exam at time non distended no tenderness other significant findings. The observed while feeding ED...

Abstract Introduction Necrotizing enterocolitis (NEC) causes significant neonatal morbidity. A subset of infants experience precipitous decline and death from fulminant-NEC (F-NEC). We sought to determine the effect feeding practices on development this more virulent form NEC. Materials Methods Premature neonates developing Bell's stage II or III NEC between May 2011 June 2017 were reviewed. Infants stratified as having F-NEC, defined NEC-totalis causing rapid within 72 hours. Risk factors...

Objective Screening for blunt intra-abdominal injury in children often includes directed laboratory evaluation that guides need computed tomography. We sought to evaluate the use of urinalysis identifying patients with clinically important intraabdominal ( ci -IAI). Methods A retrospective chart review was performed all less than 18 years who presented mechanisms at a level I trauma center between 2016 and 2019. Exclusion criteria included transfer from an outside facility, physical abuse,...

The importance of implementation strategy in systems improvement is increasingly recognized and both 'bottom-up' 'top-down' approaches have significant barriers. A trial a combined approach involving frontline managerial staff therefore seems merited. We attempted to improve handover using Human Factors-based integrated with 'top bottom' strategy.A before-after study was conducted across 9 months.The set 236 bed district general hospital.Participants included any member involved Out Hours...

Abstract Introduction To standardize care and reduce resource utilization, we implemented a standardized protocol (SP) for the nonoperative treatment of complicated appendicitis. Materials Methods We conducted prospective, historically controlled, study patients <21 years with appendicitis managed nonoperatively using an SP from January 2017 to November 2018. The primary outcomes included length stay (LOS), antibiotic days, peripheral inserted central catheter (PICC) discharge on...

Abstract The most common congenital lung malformations are pulmonary airway and sequestrations. Many surgeons advocate resection to prevent complications of infection, malignancy, pneumothorax. standard care is lobectomy, but segmentectomy embolization alone have been reported. These methods avoid the lobectomy not widely practiced due concerns about incomplete or involution lesion. We present a novel approach treatment sequestration in 7-month-old male using preoperative followed by...

We present a case of actinomycosis which resulted in symptomatic diaphragmatic hernia requiring operative repair, an unusual complication not found the literature. Actinomycosis is chronic, slowly progressive infection caused by bacterial genus Actinomyces characteristically causes necrosis and abscess formation myriad organ systems. A 5 year old male presented with nonspecific symptoms were, after short delay, identified as treated appropriate antibiosis. His was complicated development...
