Jason YostDr. Jason Yost currently splits his time between the new family medicine residency program in Eureka and a small community ER in Arcata without specialty coverage. Point of care ultrasound is an integral component of Dr. Yost’s daily practice and he uses it in approximately 20-30% of his outpatient encounters (same for ED). In the outpatient setting, he is able to provide ultrasound-guided joint injections not otherwise available in his community. In addition, Dr. Yost’s POCUS skills allow him to make bedside diagnosis of DVTs, urinary retentions/hydronephrosis, pneumonia, as well as estimate ejection fractions. Due to extremely limited resources, outpatient ultrasound takes a month to be performed, which significantly compromises patient care. Given that, POCUS offers evidence-based tools to significantly shorten diagnosis and treatment time, decrease ER visits, and improve patient satisfaction.
