Clinical Trial Summary

Bleeding from intra-abdominal injuries is a leading cause of traumatic deaths in children. Abdominal CT is the reference standard test for diagnosing intra-abdominal injuries. Compelling reasons exist, however, to both aggressively evaluate injured children for intra-abdominal injuries with CT and to limit abdominal CT evaluation to solely those at non-negligible risk. The focused assessment sonography for trauma (FAST) examination can help focus patient evaluation in just this manner by potentially safely decreasing abdominal CT use in low risk children. This research study is a multicenter, randomized, controlled trial to determine whether use of the FAST examination, a bedside abdominal ultrasound, impacts care in 3,194 hemodynamically stable children with blunt abdominal trauma. The overall objectives of this proposal are 1) to determine the efficacy of using the FAST examination during the initial evaluation of children with blunt abdominal trauma, and 2) to identify factors associated with abdominal CT use in children considered very low risk for IAI after a negative FAST examination. The long-term objective of the research is to determine appropriate evaluation strategies to optimize the care of injured children, leading to improved quality of care and a reduction in morbidity and mortality.


Description:

Trauma is a leading cause of death in children in the US. Abdominal trauma accounts for 30% of all pediatric traumatic deaths, second only to traumatic brain injury. Although CT is the reference standard for diagnosing intra-abdominal injury, it is associated with ionizing radiation, inducing malignancies at an estimated rate of 1 per 500 abdominal CT scans in children <5 years and 1 per 600 scans in adolescents. Thus, CT use should be limited to those at non-negligible risk of intra-abdominal injury. The Focused Assessment with Sonography for Trauma (FAST) examination has also evolved as a diagnostic test for the evaluation for intra-abdominal injury; however, it is used primarily in adults. The FAST examination uses abdominal ultrasonography to detect the presence of intraperitoneal fluid in injured patients. If intraperitoneal fluid is identified following a traumatic injury, this fluid is presumed to be blood (hemoperitoneum). The FAST examination for detection of hemoperitoneum in trauma consists of several images. These include a right hepatorenal interface (Morison's pouch), perisplenic view, and longitudinal and transverse views of the pelvis. Potential advantages of initial ED evaluation of the injured child using the FAST examination include: 1) bedside evaluation during initial patient ED evaluation and resuscitation; 2) rapid completion of the diagnostic test (within 3-5 minutes); 3) performance of the test and interpretation of results by ED physicians or trauma surgeons caring for the child; 4) no radiation exposure; and 5) reduced patient-care costs compared to routine use of abdominal CT. In adults, a positive FAST examination is the best predictor of intra-abdominal injury. In two adult randomized controlled trials, the use of FAST demonstrated improved patient care by decreasing abdominal CT use, complications and costs. Although the sensitivity of the FAST exam for intra-abdominal injury is lower than CT, as a screening test, it may decrease the need for abdominal CT in both low risk injured adults and children. The long-term objective of this research study is to determine appropriate evaluation strategies to optimize the care of injured children, leading to improved quality of care and a reduction in morbidity and mortality. The specific aims of this proposal are to: 1) perform a randomized, controlled trial of the FAST examination in injured children and compare the frequency of abdominal CT scanning between children who are randomized to the FAST and non-FAST arms; 2) identify if an evaluation strategy including the FAST examination results in a similar frequency of missed or delayed diagnoses of intra-abdominal injuries than a strategy without the FAST examination; and 3) identify patient, physician, and system factors associated with obtaining abdominal CT scans in patients considered low risk for intra-abdominal injuries by the clinician after a negative FAST examination. Such a study has the potential for significant impact in improving the lives of injured children, if found to be successful. This randomized controlled trial will follow the methods of the one prior randomized controlled trial of FAST in injured children which enrolled 925 injured children at a single center. This study incorporate a total of six centers to increase the sample size and generalizability of the results.

Age group N/A to 17 Years
Eligibility Children younger than 18 years of age (0 to 17.9999 years) with blunt abdominal trauma presenting to the participating EDs within 24 hours of the traumatic event will be eligible if the do not meet any exclusion criteria and meet any one of the following inclusion criteria. Inclusion Criteria: 1. Blunt torso trauma resulting from a significant mechanism of injury: - Motor vehicle collision: greater than 60 mph, ejection, or rollover - Automobile versus pedestrian/bicycle: automobile speed > 25 mph - Falls greater than 20 feet in height - Crush injury to the torso - Physical assault involving the abdomen 2. Decreased level of consciousness (Glasgow Coma Scale (GCS) score 9-14 or below age-appropriate behavior) in association with blunt torso trauma 3. Blunt traumatic event with any of the following (regardless of the mechanism): - Extremity paralysis - Multiple long bone fractures (e.g., tibia and humerus fracture) 4. History and physical examination suggestive of blunt torso trauma of any mechanism (including mechanisms of injury of less severity than mentioned above) Exclusion Criteria: The following patients will be excluded from the study: 1. Age-adjusted low blood pressure (Hemodynamic instability) - Patients will be excluded for prehospital or initial age-adjusted ED low blood pressure. This is because the standard evaluation of these patients involves immediate FAST based on prior work by our group. Low blood pressure is determined based upon the patient's age, and will be defined as a systolic blood pressure less than 70 mm Hg for patients younger than 1 month, less than 80 mm Hg for ages 1 month to 5 years, and less than 90 mm Hg for ages over 5 years. 2. Penetrating trauma: Patients who are victims of stab or gunshot wounds 3. Traumatic injury occurring > 24 hours prior to the time of presentation to the ED 4. Transfer of the patient to the ED from an outside facility with abdominal CT scan, diagnostic peritoneal lavage, or laparotomy previously performed 5. Transferred with FAST exam already performed at outside hospital 6. Patients with known disease processes resulting in intraperitoneal fluid including liver failure and the presence of ventriculoperitoneal shunts 7. Initial GCS score = 8 as it is standard for children with GCS scores = 8 to undergo abdominal CT if blunt abdominal trauma is suspected 8. Known pregnancy 9. Known prisoner 10. Known intra-abdominal injury diagnosed within 30 days prior of this ED visit

Study Design


Intervention

Diagnostic Test:
Focused Assessment with Sonography for Trauma (FAST) Examination
A bedside Focused Assessment with Sonography for Trauma (FAST) Examination will be conducted on those participants who are randomized to the FAST arm.
Other:
No Intervention: Standard of Care - Without the FAST Examination
Participants randomized to usual care will be evaluated per the standard operating procedures of the institution/site for the condition under study without the FAST exam.

Outcome

Type Measure Description Time frame Safety issue
Primary Rate of abdominal CT scanning The primary outcome is the rate of abdominal CT scanning in each study arm, measured for each patient categorically (yes/no) during the Emergency Department stay and initial hospitalization (up to 24 hours). For the duration of the subject's Emergency Department stay and initial hospitalization (up to 24 hours)
Primary Rate of delayed or missed or delayed intra-abdominal injuries The rate of missed or delayed intra-abdominal injuries (IAI) will be identified and reported for any cases with a delay in diagnosis (i.e., patients diagnosed with IAI in the hospital after ED disposition) or missed IAI (IAI diagnosed after discharge from the ED/hospital). In hospitalized participants, IAI collection will be captured from the time of assignment until discharge (up to 30 days). For participants discharged from the ED IAI collection will be captured from the time of assignment until 7 days after ED discharge
Primary Identifying variables associated with obtaining abdominal CT scans in very low risk patients with normal FAST examinations This primary outcome will be a binary indicator (yes/no) for whether the patient with a normal FAST examination who is thought by the clinician to have less than a 1% risk of intra-abdominal injury nonetheless undergoes abdominal CT (outcome of interest). The binary indicator assessment of yes/no will occur upon discharge from the Emergency Department or admission to the hospital, an average of 6.5 hours
Secondary Emergency Department (ED) length of stay ED length of stay is a continuous variable measured in minutes. The investigators will compare the ED length of stay between study arms using nonparametric methods (time from ED arrival to hospital admission or time from ED arrival until ED discharge). ED length of stay will be calculated in minutes from the time of ED arrival until the time of ED discharge or the time from ED arrival until the time of hospital admission assessed up to 7 days.
Secondary Rate of Hospitalization Rate of hospitalization is a categorical variable (yes/no) on whether the patient is hospitalized on initial, enrolling ED visit. The investigators will compare the rate of hospitalization between study arms using categorical statistical methods. The assessment of the categorical variable yes/no will occur upon the participants discharge from the Emergency Department or admission to the hospital, an average of 6.5 hours
Secondary Physician suspicion of intra-abdominal injury Physician suspicion of intra-abdominal injury is collected after initial physician evaluation for all patients. For those patients who are randomized to the FAST examination this information is collected again after completing the FAST examination. Physician suspicion is collected as follows: Less than 1%, 1-5%, 6-10%, 11-50%, greater than 50%. All physician suspicion assessments will occur up to 24 hours after a participants ED presentation
Secondary Rate of abdominal CT scanning in children 0 to 3 years of age. In this prespecified age group, the outcome is the rate of abdominal CT scanning in each study arm, measured for each patient categorically (yes/no) during the Emergency Department stay and initial hospitalization (up to 24 hours). For the duration of the subject's Emergency Department stay and initial hospitalization (up to 24 hours).
Secondary Laparotomy (surgery to the abdomen) rate Laparotomy rate is a binary indicator (yes/no) for whether the patient underwent a laparotomy (surgery to the abdomen) to identify/repair an intra-abdominal injury. For the first seven days after the time of injury.
