Dr. Arufe completed medical school at Universidad del Salvador, Buenos Aires, Argentina, in 2005 and residency in internal medicine at the Instituto de Investigaciones Médicas ¨Alfredo Lanari¨ in 2010 and then did a hepatology and liver transplant fellowship at Hospital Universitario Austral until 2013. During his fellowship and through 2018, he worked as an intensive care unit physician at Sanatorio Mater Dei, Buenos Aires. Currently, he is hepatologist at Sanatorio Sagrado Corazon and Hospital Universitario Austral, Buenos Aires, Argentina and runs the hepatology fellowship program there. His interest in ultrasound started in 2009. He did the post graduate course on ultrasound and doppler at ¨Sociedad Argentina de Ultrasonografia en Medicina y Biologia (SAUMB)¨ 2009-2010. He started to apply the concept of POCUS in hepatology 9 years ago and has been using POCUS ever since. And coined the term HEPOCUS (also his twitter handle) which to him means strategically using ultrasound to answer liver-related clinical questions and improve patient care. He has coordinated the HEPOCUS course at the Sociedad Argentina de Hepatologia (SAHE). He is also a specialist in liver elastography. He believes that POCUS has changed the face of medicine, and specifically believes in the power of HEPOCUS to improve the speed and accuracy of diagnosis, and improve patient care.

Jason Yost

Dr. 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.
