A critical appraisal of the quality of adult dual-energy X-ray absorptiometry guidelines in osteoporosis using the AGREE II tool: An EuroAIM initiative

Abstract

Objectives

Dual energy X-ray absorptiometry (DXA) is the most widely used technique to measure bone mineral density (BMD). Appropriate and accurate use of DXA is of great importance, and several guidelines have been developed in the last years. Our aim was to evaluate the quality of published guidelines on DXA for adults.

Methods

Between June and July 2016 we conducted an online search for DXA guidelines, which were evaluated by four independent readers blinded to each other using the AGREE II instrument. A fifth independent reviewer calculated scores per each domain and agreement between reviewers' scores.

Results

Four out of 59 guidelines met inclusion criteria and were included. They were published between 2005 and 2014. Three out of four guidelines reached a high level of quality, having at least five domain scores higher than 60%. Domain 1 (Scope and Purpose) achieved the highest result (total score = 86.8 ± 3.7%). Domain 6 (Editorial Independence) had the lowest score (total score = 54.7 ± 12.5%). Interobserver agreement ranged from fair (0.230) to good (0.702).

Conclusions

Overall, the quality of DXA guidelines is satisfactory when evaluated using the AGREE II instrument. The Editorial Independence domain was the most critical, thus deserving more attention when developing future guidelines.

Main messages

• Three of four guidelines on DXA had a high quality level (>60%).

• Scope/purpose had the highest score (86.8 ± 3.7%).

• Editorial Independence had the lowest score (54.7 ± 12.5%).

• Interobserver agreement ranged from fair (0.230) to good (0.702).
