Point-of-Care Ultrasonography for the Diagnosis of Skin and Soft Tissue Abscesses: A Systematic Review and Meta-analysis.
Skin and soft tissue infections are a common chief complaint in the emergency department. Research has shown that clinical examination alone can be unreliable in distinguishing between cellulitis and abscesses, a distinction that is important because they each require different treatments. Point-of-care ultrasonography has been increasingly studied as a tool to improve the diagnostic accuracy for these skin and soft tissue infections. The primary objective of this systematic review is to evaluate the diagnostic accuracy of point-of-care ultrasonography for abscesses. Subgroup analyses are performed for adult versus pediatric patients and high suspicion versus clinically unclear cases. Secondary objectives include the percentage of correct versus incorrect changes in management and reduction in treatment failures because of point-of-care ultrasonography. ⋯ According to the current data, point-of-care ultrasonography has good diagnostic accuracy for differentiating abscesses from cellulitis and led to a correct change in management in 10% of cases. Future studies should determine the ideal training and image acquisition protocols.
