An Evaluation of the Accuracy of Point of Care Ultrasound by Family Physicians in Rural British Columbia, Canada: Methodological Insights

We found interpretation agreement among imaging experts for a minority of scans, resulting in inadequate power to assess the diagnostic accuracy of PoCUS by rural FPs. When using secondary image review to assess rural PoCUS quality, we recommend limiting the number of PoCUS working diagnoses being investigated, developing image sharing guidelines for FP participants, and using consensus agreement by multiple experts as the reference standard.
