Inter-rater Reliability of Sonographic Optic Nerve Sheath Diameter Measurements by Emergency Medicine Physicians.
To compare the degree of agreement of sonographic optic nerve sheath diameter (ONSD) measurements by ultrasound fellowship-trained and resident emergency medicine (EM) physicians. ⋯ Although both resident and ultrasound fellowship-trained EM physicians showed good inter-rater reliability of ONSD measurements, variation in agreement among ultrasound fellowship-trained EM physicians may be as wide as 0.44, suggesting that even in skilled hands, ultrasound measurement of the ONSD may not be as dependable a screening tool for elevated intracranial pressure as previously suggested in the literature.
