Research and scholarship advance the field and establish the evidence for our use of POCUS across all specialties of medicine. Take a look at our regularly updated Zotero library of POCUS literature. We are also dedicated to delivering high quality and innovative research in POCUS, so check out our featured publications.
Just the Facts publication about the role of POCUS for skin and soft tissue infections, specifically cellulitis, abscess, and necrotizing fasciitis. It provides guidance about how to perform the scan, as well as how POCUS can be used to assist with incision and drainage of abscesses.
A meta-research study of systematic reviews assessing the diagnostic accuracy of POCUS applications. This study attempted to characterize the completeness of reporting using the PRISMA-DTA checklist. Overall, systematic reviews of POCUS diagnostic accuracy were moderately reported, but the main areas of deficiency were systematic review registration and the identification of a minimally acceptable test accuracy threshold.
Observational study of 110 patients to assess the change in the position of the cricothyroid landmark from 0° head of bed elevation to 30° and 90°. Elevating the head of bed to 30° results in a cephalad change of 2.7 mm in the landmark, and elevating to 90° results in a cephalad change of 4.2 mm. This may be clinically important when attempting cricothyrotomy using a percutaneous (blind) technique.
Consensus recommendations from the CAEP Emergency Ultrasound Comittee on POCUS use in patients with known or suspected COVID-19, with an emphasis on machine infection control measures.
Editorial about a study describing an impressive system-wide POCUS credentialing effort, involving 91 emergency physicians and 11 hospitals in one and a half years. Key prinicples for success included system leadership support, robust POCUS workflow, standardized machines, and privileging by POCUS skill level (instead of by application).
Multispecialty response letter to address the misconceptions and misinformation in CAR's POCUS position statement that was published in August 2019. This response is endorsed by CAEP, ACEP, CAS, CPOCUS, CCCUC, SCUF, CIMUG & P2Network.
CAEP’s new POCUS position statement with expansive recommendations about scope of practice, training and competency, program management, pediatric POCUS, and research.
A prospective diagnostic test assessment of POCUS for retinal detachment. We enrolled 115 patients; sensitivity and specificity of POCUS for detecting retinal detachment were 75% and 94%, respectively.
