Performance of Pediatric Emergency Medicine Faculty After Point-of-Care Ultrasound Credentialing Implementation

Abstract

Objective: As point-of-care ultrasound (POCUS) continues to evolve, a national standardized curriculum for training and credentialing pediatric emergency medicine (PEM) physicians is still lacking. The goal of this study was to assess PEM faculty in performing and interpreting POCUS during implementation of a training curriculum.

Methods: Sixteen full-time PEM faculty with either limited or no prior POCUS experience were trained to perform 4 ultrasound studies. Twelve of the 16 completed the training with a goal of credentialing within 12 months of implementation. For each faculty, we assessed competency by comparing precurriculum and postcurriculum test assessments and by evaluating quality of POCUS acquisition and accuracy of interpretation. We also monitored the amount of continuing medical education (CME) hours completed to ensure a minimum didactic component.

Results: We found a significant improvement in POCUS competency comparing precurriculum to postcurriculum test assessments (55.4% vs 75.6%, P < 0.0002). One thousand two hundred seventy images were submitted over the course of the curriculum. Accuracy, sensitivity, and specificity were 98.23% (confidence interval [CI] = 97.18-98.97), 97.01% (CI = 92.53-99.81), and 98.43% (CI = 97.33-99.81), respectively. Faculty self-rating of image quality was significantly higher than expert reviewer rating of image quality (3.4 ± 0.86 vs 3.2 ± 0.56, P < 0.0001). We found no change in expert reviewer rating of image quality over time. Faculty completed a combined 232.5 CME hours (average, 17.4 ± 10.8), with the majority of hours coming from an institutional POCUS CME workshop.

Conclusions: These results show that a structured curriculum can improve PEM faculty POCUS competency.
