We Support POCUS Scholarship

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.

Primer%20for%20Clinical%20POCUS%20Leadership

A primer for clinical POCUS leadership in your emergency department
CJEM 2023

This is a resource document published in CJEM providing advice about best practices for clinical POCUS program management. We specifically highlight the role of the POCUS director, training and granting of POCUS privileges, elements of a quality assurance and improvement program, and ultrasound machine purchase and maintenance. The supplement includes an example business case for financial support of a POCUS program.

PTA%20Systematic%20Review

Test characteristics of ultrasound for the diagnosis of peritonsillar abscess: a systematic review and meta-analysis
Acad Emerg Med 2023

This was a systematic review and meta-analysis to determine the test characteristics of ultrasound for diagnosing peritonsillar abscess. We included 17 studies with 812 patients, 541 of whom had peritonsillar abscess. The pooled sensitivity of ultrasound was 86% and specificity was 76%, so highly sensitive but only moderately specific for peritonsillar abscess.
PMID: 36625850

EFSUMB%20Heart%20and%20Pulmonary

EFSUMB clinical practice guidelines for point-of-care ultrasound: Part one (common heart and pulmonary applications)
Ultraschall Med 2022

This was an international effort led by Bob Jarman, Anna Colclough, and Cian McDermott and endorsed by the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) to provide recommendations on commonly used heart and lung POCUS applications, including the assignment of levels of evidence (LoE) and grading of the recommendations (using the GRADE framework).

POCUS%20Lit%20FAST%20and%20E FAST

Point of care ultrasound literature primer: Key papers on FAST and E-FAST
Cureus 2022

We used a modified Delphi process with an expert panel recruited from the CAEP Emergency Ultrasound Committee and the Canadian Ultrasound Fellowship Collaborative. After completing 3 rounds of sequential surveys, we ultimately identified the top 5 most influential papers on FAST and on E-FAST.

Ultrasound%20PTX%20Letter

Ultrasound is superior to supine chest x-ray for the diagnosis of clinically relevant traumatic pneumothorax
Trauma Acute Care Surg 2022

A letter to the editor in the Journal of Trauma and Acute Care Surgery addressing a highly flawed study on the use of ultrasound in traumatic pneumothorax. The study in question retrospectively found a sensitivity of ultrasound for traumatic pneumothorax far lower than the current published literature. We highlight many methodologic issues with the study design that limit the applicability of their conclusions.
PMID: 35293371

POCUS%20in%20Canadian%20EM%20Residency%20Programs%202022

Point of care ultrasound training in Canadian emergency medicine residency programs
CJEM 2022

Study providing the most complete and current description of POCUS training in Canadian emergency medicine residency programs. POCUS training in Canadian emergency medicine programs is prevalent, but there is variability in support for POCUS leads, delivery of training, determination of proficiency, and presence of quality assurance.
PMID: 35239169

Compartment%20Syndrome%20POCUS

Adjunctive use of point of care ultrasound to diagnose compartment syndrome of the thigh
POCUS J 2021

A case report describing the identification of a large anterior thigh hematoma on POCUS in a patient with delayed compartment syndrome of the thigh. The POCUS Journal is a completely open access publication with no publication or access fees.
https://doi.org/10.24908/pocus.v6i2.15185

POCUS%20Picture

A picture is worth a thousand words, but only if you can see it
CJEM 2021

A letter to the editor calling for Canadian healthcare systems to invest more resources in digital archiving systems for POCUS. “There needs to be advocacy for hospitals to provide appropriate IT funding and resources to implement digital archiving systems, and alternate avenues such as the crowdsourcing of low-cost workflow solutions needs to be explored."
PMID: 34797557
