Is underdiagnosis of vertebral fractures a worldwide problem : the IMPACT study?
Underdiagnosis of vertebral fractures was observed in all geographic regions (false-negative rates: North America, 45.2%; Latin America, 46.5%; Europe/South Africa/Australia, 29.5%). The false-positive rate was 5% globally. Underdiagnosis of vertebral fracture is a worldwide problem attributable in part to a lack of radiographic detection, use of ambiguous terminology in the radiology report, or both. Efforts to improve accuracy and reduce variability in terminology and interpretation may increase the effectiveness of spinal radiography for detecting vertebral fractures in patients with osteoporosis.
The results of this preliminary study demonstrate a significant correlation between academic output and mortality rates. The correlation coefficients are small, but the findings of this study encourage further debate.
