Clinical Trial Summary

The purpose of this study is to determine if pediatric emergency medicine providers can accurately diagnose a hip effusion using point-of-care ultrasound (POCUS) compared to radiology ultrasound (RADUS).

Description:

The purpose of this study is to determine that the accuracy of trained pediatric emergency medicine providers to diagnose hip effusion using point-of-care ultrasound (POCUS) is non-inferior to the reference standard of radiology ultrasound (RADUS). Additionally, the investigators seek to compare how POCUS performs against other clinical tests or investigations for the diagnosis of septic arthritis. The investigators hypothesize that trained EM providers will be able to diagnose hip effusions with high (>90%) accuracy compared to studies conducted by the Department of Radiology.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Number of point-of-care ultrasound studies performed by PEM providers that have a different final diagnosis when compared to radiology ultrasound.	Investigators will compare the final diagnosis (hip effusion or no hip effusion) between point-of-care-ultrasound and radiology ultrasound to determine the number of discrepancies between the groups.	Upon chart review: between the time the measurement was obtained in the emergency department up to six weeks later when the chart is reviewed by primary investigator.
Other	Association between negative point-of-care ultrasound and low to moderate Kocher score.	Investigators will determine whether the use of ultrasonography in patients with low or moderate Kocher score improves the ability to rule out septic arthritis.	Upon chart review: between the time the measurement was obtained in the emergency department up to six weeks later when the chart is reviewed by primary investigator.
Primary	The presence or absence of a hip effusion.	The presence or absence of an effusion as determined by the pediatric emergency medicine physician performing the point-of-care-ultrasound study on both the affected and unaffected sides (i.e. right hip and left hip).	From the time the point-of-care ultrasound is performed by the physician during the emergency department visit through study completion, average of 2 years.
Primary	The presence of absence of a hip effusion.	The presence or absence of an effusion as determined by the Radiologist on both the affected and unaffected sides.	From the time the radiologist reviews the ultrasound as performed by the radiology technician during the emergency department visit, through study completion, average of 2 years.
Secondary	The size of the effusion.	As measured by the pediatric emergency medicine provider in millimeters.	From the time the point-of-care ultrasound is performed by the physician during the emergency department visit to study completion, average of 2 years
Secondary	The location of the measurement of the effusion.	Pediatric emergency medicine physicians will measure an effusion at two designated locations. One location is based off of current published literature whereas the second is to provide a comparison to determine if the exact location alters the final diagnosis (effusion or no effusion). Investigators will determine whether the location along the angle of the neck affects the measurement obtained when compared with the current standard practice of measuring fluid along the widest part of the femoral neck.	Upon chart review: between the time the measurement was obtained in the emergency department up to six weeks later when the chart is reviewed by primary investigator.
