Rapid brain MRI protocols reduce head computerized tomography use in the pediatric emergency department.

ABSTRACT:

Background

Rapid magnetic resonance imaging (MRI) protocols may be effective in the emergency department (ED) to evaluate nontraumatic neurologic complaints. We evaluate neuroimaging (rapid MRI [rMRI]), head computerized tomography [HCT], and full MRI) use following widespread implementation of rMRI protocols in a pediatric emergency department (ED).

Methods

We conducted a retrospective study in a tertiary care pediatric ED of encounters with neuroimaging during two 9-month periods: one prior to (control period) and one after generalized availability of 4 rMRI protocols (rMRI period). The primary outcome was differences in neuroimaging rates between the two periods. Secondary outcomes included ED process measures, unsuccessful imaging, and undetected pathology, with full MRI within 14?days as the reference standard.

Results

There were 1052 encounters with neuroimaging during the control and 1308 during the rMRI periods. Differences in neuroimaging between periods were 27.7% for rMRI (95% CI, 24.4, 31.0), -?21.5% for HCT (95% CI, -?25.5, -?17.5), and?-?6.2% for full MRI (95% CI, -?9.3, -?3.1%.) Time to imaging (182 [IQR 138-255] versus 86 [IQR 52-137] minutes) as well as ED length of stay (396 [IQR 304-484] versus 257 [IQR 196-334] minutes) was longer for rMRI versus HCT (p?ConclusionsAfter routine ED use of 4 rMRI protocols, there was a more than 20% decrease in HCT use without missed diagnoses. Time to neuroimaging and length of stay were longer for rMRI than HCT, with higher rates of unsuccessful imaging. Despite these limitations, rMRI may be an alternative to HCT for nontraumatic complaints in the ED.

Project description:PurposeMore than 1 million patients annually seek care in an emergency department for kidney stones but a minority require hospital admission or a urological procedure. We describe predictors of hospital admission or urological intervention.Materials and methodsThis secondary analysis of prospective data included patients with an obstructing ureteral stone that was confirmed by computerized tomography in an emergency department. All patients also underwent point of care limited renal ultrasound. The need for urological intervention at 90 days was assessed by a followup interview. Logistic regression was used to identify predictors of admission and urological intervention, which were further stratified by disposition. Separate regression models with and without computerized tomography findings (point of care limited renal ultrasound only) were compared using c-statistics.ResultsAmong a cohort of 475 patients with a symptomatic stone on computerized tomography 95 (20%) were admitted and 68 (72%) received an intervention. Of 380 discharged patients 66 (17%) required urological intervention. Admitted patients were more likely to have undergone a prior procedure, have evidence of kidney injury or infection, need opiate analgesia or have larger stones or hydronephrosis on point of care limited renal ultrasound. Predictors of intervention varied by disposition. However, regression models with and without computerized tomography findings demonstrated similar c-statistics. Discharged patients with larger stones, a longer pain duration at presentation and prior procedures were more likely to undergo intervention.ConclusionsIntervention was common among admitted patients but it occurred in a minority of those discharged. Predictors of intervention varied by disposition. Models incorporating computerized tomography findings were similar to those that did not incorporate such findings. These data support ultrasound first or delayed computerized tomography diagnostic pathways for patients deemed clinically suitable for discharge home.

Project description:This study aims to evaluate the efficacy of the PECARN Rule (PR) in reducing radiological investigations in children with mild traumatic head injury in comparison with current clinical practice. A retrospective study was performed in our hospital between July 2015 and June 2020. Data of all children < 18 years of age admitted to the emergency department (ED), within 24 h after a head trauma with GCS ≥ 14, were analyzed. PECARN Rule was retrospectively applied to all patients. In total, 3832 patients were enrolled, 2613 patients ≥ 2 years and 1219 < 2 years. In the group of children ≥ 2 years, 10 presented clinically important traumatic brain injury (ciTBI) and were hospitalized, 7/10 underwent neurosurgery, and 3/10 clinical observation in the pediatric ward for more than 48 h. In children < 2 years, only 3 patients presented ciTBI, 2 underwent neurosurgery and 1 hospitalized. Applying the PR, no patient with ciTBI would have been discharged without an accurate diagnosis and we would have avoided 139 CT scans in patients ≥ 2 years, and 23 in those < 2 years of age (29% less).ConclusionWe demonstrated the safety and validity of the PR in our setting with 100% sensitivity in both age groups in identifying patients with ciTBI and theoretically in reducing performed CT scans by 29%. Therefore, in patients classified in the low-risk category, it is a duty not to expose the child to ionizing radiation.What is known• CT is the gold standard to identify intracranial pathology in children with head injury but CT imaging of head-injured children expose them to higher carcinogenic risk. • PECARN Rules support doctors in identifying children with ciTBI in order to reduce exposure to ionizing radiation.What is new• We demonstrate the safety and validity of the PR with 100% sensitivity in both age groups in identifying patients with ciTBI. • In our setting, the application of PECARN Rule would theoretically have allowed us to reduce the CT scan by 29%.
