Accuracy of Pediatric Emergency Medicine Providers in Diagnosing Hip Effusions Using Point of Care Ultrasound

Connecticut Children's Medical Center161 enrolled

Overview

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).

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.

Outcomes

Primary Outcomes

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).

Time frame: 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.

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.

Time frame: 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 Outcomes

The size of the effusion.

As measured by the pediatric emergency medicine provider in millimeters.

Time frame: 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

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.

Time frame: 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.
