Objective:To evaluate a short educational intervention instructing primary care physicians in the recognition of glaucomatous changes of the optic disc.
Design:Comparison of performances on a pretest and a posttest consisting of fundus slides in color.
Setting:Educational conferences at two university-affiliated teaching hospitals and one staff-model bealth maintenance organization.
Subjects:Thirty-six internal medicine residents and ten practicing internists.
Intervention:A 20-minute slide/narration educational program, which covered diagnostic criteria for openangle glaucoma, normal and abnormal optic disc anatomy, and funduscopic signs of open-angle glaucoma.
Measurements and main results:Following the intervention, residents showed improved sensitivity (0.76 to 0.88, p=0.007), specificity (0.65 to 0.88, p<0.001), and accuracy (0.71 to 0.88, p<0.001). Internists showed similar increments in sensitivity, specificity, and accuracy: 0.67 to 0.86 (p=0.01), 0.59 to 0.84 (p=0.01), and 0.63 to 0.85 (p=0.002), respectively.
Conclusion:A brief educational intervention can result in meaningful improvement in physician diagnostic accuracy in recognizing ophthalmoscopic signs of open-angle glaucoma.
